CHAPTER I. SCOPE OF APPLICATION 
Article 1. Scope of application 
(1) This Convention applies to an international undertaking referred to in article 2: 
(a) If the place of business of the guarantor/issuer at which the undertaking is issued is in a Contracting State, or 
(b) If the rules of private international law lead to the application of the law of a Contracting State, unless the undertaking excludes the application of the Convention. 
(2) This Convention applies also to an international letter of credit not falling within article 2 if it expressly states that it is subject to this Convention. 
(3) The provisions of articles 21 and 22 apply to international undertakings referred to in article 2 independently of paragraph (1) of this article. 
Article 2. Undertaking 
(1) For the purposes of this Convention, an undertaking is an independent commitment, known in international practice as an independent guarantee or as a stand-by letter of credit, given by a bank or other institution or person ("guarantor/issuer") to pay to the beneficiary a certain or determinable amount upon simple demand or upon demand accompanied by other documents, in conformity with the terms and any documentary conditions of the undertaking, indicating, or from which it is to be inferred, that payment is due because of a default in the performance of an obligation, or because of another contingency, or for money borrowed or advanced, or on account of any mature indebtedness undertaken by the principal/applicant or another person. 
(2) The undertaking may be given: 
(a) At the request or on the instruction of the customer ("principal/applicant") of the guarantor/issuer; 
(b) On the instruction of another bank, institution or person ("instructing party") that acts at the request of the customer ("principal/applicant") of that instructing party; or 
(c) On behalf of the guarantor/issuer itself. 
(3) Payment may be stipulated in the undertaking to be made in any form, including: 
(a) Payment in a specified currency or unit of account; 
(b) Acceptance of a bill of exchange (draft); 
(c) Payment on a deferred basis; 
(d) Supply of a specified item of value. 
(4) The undertaking may stipulate that the guarantor/issuer itself is the beneficiary when acting in favour of another person. 
Article 3. Independence of undertaking 
For the purposes of this Convention, an undertaking is independent where the 
guarantor/issuer's obligation to the beneficiary is not: 
(a) Dependent upon the existence or validity of any underlying transaction, or 
upon any other undertaking (including stand-by letters of credit or 
independent guarantees to which confirmations or counter-guarantees relate); or 
(b) Subject to any term or condition not appearing in the undertaking, or to 
any future, uncertain act or event except presentation of documents or another 
such act or event within a guarantor/issuer's sphere of operations. 



Article 4. Internationality of undertaking 


(1) An undertaking is international if the places of business, as specified in 
the undertaking, of any two of the following persons are in different States: 
guarantor/issuer, beneficiary, principal/applicant, instructing party, 
confirmer. 


(2) For the purposes of the preceding paragraph: 


(a) If the undertaking lists more than one place of business for a given 
person, the relevant place of business is that which has the closest 
relationship to the undertaking; 

(b) If the undertaking does not specify a place of business for a given person 
but specifies its habitual residence, that residence is relevant for 
determining the international character of the undertaking. 




CHAPTER II. INTERPRETATION 


Article 5. Principles of interpretation 


In the interpretation of this Convention, regard is to be had to its 
international character and to the need to promote uniformity in its application 
and the observance of good faith in the international practice of independent 
guarantees and stand-by letters of credit. 


Article 6. Definitions 


For the purposes of this Convention and unless otherwise indicated in a 
provision of this Convention or required by the context: 


(a) "Undertaking" includes "counter-guarantee" and "confirmation of an 
undertaking"; 

(b) "Guarantor/issuer" includes "counter-guarantor" and "confirmer"; 

(c) "Counter-guarantee" means an undertaking given to the guarantor/issuer of 
another undertaking by its instructing party and providing for payment upon 
simple demand or upon demand accompanied by other documents, in conformity 
with the terms and any documentary conditions of the undertaking, indicating, 
or from which it is to be inferred, that payment under that other undertaking 
has been demanded from, or made by, the person issuing that other undertaking; 


(d) "Counter-guarantor" means the person issuing a counter-guarantee; 

(e) "Confirmation" of an undertaking means an undertaking added to that of the 
guarantor/issuer, and authorized by the guarantor/issuer, providing the 
beneficiary with the option of demanding payment from the confirmer instead of 
from the guarantor/issuer, upon simple demand or upon demand accompanied by 
other documents, in conformity with the terms and any documentary conditions 
of the confirmed undertaking, without prejudice to the beneficiary's right to 
demand payment from the guarantor/issuer; 

(f) "Confirmer" means the person adding a confirmation to an undertaking; 

(g) "Document" means a communication made in a form that provides a complete 
record thereof. 

CHAPTER III. FORM AND CONTENT OF UNDERTAKING 


Article 7. Issuance, form and irrevocability of undertaking 


(1) Issuance of an undertaking occurs when and where the undertaking leaves the 
sphere of control of the guarantor/issuer concerned. 


(2) An undertaking may be issued in any form which preserves a complete record 
of the text of the undertaking and provides authentication of its source by 
generally accepted means or by a procedure agreed upon by the guarantor/issuer 
and the beneficiary. 


(3) From the time of issuance of an undertaking, a demand for payment may be 
made in accordance with the terms and conditions of the undertaking, unless the 
undertaking stipulates a different time. 


(4) An undertaking is irrevocable upon issuance, unless it stipulates that it is 
revocable. 


Article 8. Amendment 


(1) An undertaking may not be amended except in the form stipulated in the 
undertaking or, failing such stipulation, in a form referred to in paragraph (2) 
of article 7. 


(2) Unless otherwise stipulated in the undertaking or elsewhere agreed by the 
guarantor/issuer and the beneficiary, an undertaking is amended upon issuance of 
the amendment if the amendment has previously been authorized by the 
beneficiary. 


(3) Unless otherwise stipulated in the undertaking or elsewhere agreed by the 
guarantor/issuer and the beneficiary, where any amendment has not previously 
been authorized by the beneficiary, the undertaking is amended only when the 
guarantor/issuer receives a notice of acceptance of the amendment by the 
beneficiary in a form referred to in paragraph (2) of article 7. 


(4) An amendment of an undertaking has no effect on the rights and obligations 
of the principal/applicant (or an instructing party) or of a confirmer of the 
undertaking unless such person consents to the amendment. 


Article 9. Transfer of beneficiary's right to demand payment 


(1) The beneficiary's right to demand payment may be transferred only if 
authorized in the undertaking, and only to the extent and in the manner 
authorized in the undertaking. 


(2) If an undertaking is designated as transferable without specifying whether 
or not the consent of the guarantor/issuer or another authorized person is 
required for the actual transfer, neither the guarantor/issuer nor any other 
authorized person is obliged to effect the transfer except to the extent and in 
the manner expressly consented to by it. 


Article 10. Assignment of proceeds 


(1) Unless otherwise stipulated in the undertaking or elsewhere agreed by the 
guarantor/issuer and the beneficiary, the beneficiary may assign to another 
person any proceeds to which it may be, or may become, entitled under the 
undertaking. 


(2) If the guarantor/issuer or another person obliged to effect payment has 
received a notice originating from the beneficiary, in a form referred to in 
paragraph (2) of article 7, of the beneficiary's irrevocable assignment, payment 
to the assignee discharges the obligor, to the extent of its payment, from its 
liability under the undertaking. 


Article 11. Cessation of right to demand payment 


(1) The right of the beneficiary to demand payment under the undertaking ceases 
when: 


(a) The guarantor/issuer has received a statement by the beneficiary of 
release from liability in a form referred to in paragraph (2) of article 7; 

(b) The beneficiary and the guarantor/issuer have agreed on the termination of 
the undertaking in the form stipulated in the undertaking or, failing such 
stipulation, in a form referred to in paragraph (2) of article 7; 

(c) The amount available under the undertaking has been paid, unless the 
undertaking provides for the automatic renewal or for an automatic increase of 
the amount available or otherwise provides for continuation of the 
undertaking; 

(d) The validity period of the undertaking expires in accordance with the 
provisions of article 12. 

(2) The undertaking may stipulate, or the guarantor/issuer and the beneficiary 
may agree elsewhere, that return of the document embodying the undertaking to 
the guarantor/issuer, or a procedure functionally equivalent to the return of 
the document in the case of the issuance of the undertaking in non-paper form, 
is required for the cessation of the right to demand payment, either alone or in 
conjunction with one of the events referred to in subparagraphs (a) and (b) of 
paragraph (1) of this article. However, in no case shall retention of any such 
document by the beneficiary after the right to demand payment ceases in 
accordance with subparagraph (c) or (d) of paragraph (1) of this article 
preserve any rights of the beneficiary under the undertaking. 


Article 12. Expiry 


The validity period of the undertaking expires: 


(a) At the expiry date, which may be a specified calendar date or the last day 
of a fixed period of time stipulated in the undertaking, provided that, if the 
expiry date is not a business day at the place of business of the 
guarantor/issuer at which the undertaking is issued, or of another person or 
at another place stipulated in the undertaking for presentation of the demand 
for payment, expiry occurs on the first business day which follows; 

(b) If expiry depends according to the undertaking on the occurrence of an act 
or event not within the guarantor/issuer's sphere of operations, when the 
guarantor/issuer is advised that the act or event has occurred by presentation 
of the document specified for that purpose in the undertaking or, if no such 
document is specified, of a certification by the beneficiary of the occurrence 
of the act or event; 

(c) If the undertaking does not state an expiry date, or if the act or event 
on which expiry is stated to depend has not yet been established by 
presentation of the required document and an expiry date has not been stated 
in addition, when six years have elapsed from the date of issuance of the 
undertaking. 



CHAPTER IV. RIGHTS, OBLIGATIONS AND DEFENCES 


Article 13. Determination of rights and obligations 


(1) The rights and obligations of the guarantor/issuer and the beneficiary 
arising from the undertaking are determined by the terms and conditions set 
forth in the undertaking, including any rules, general conditions or usages 
specifically referred to therein, and by the provisions of this Convention. 


(2) In interpreting terms and conditions of the undertaking and in settling 
questions that are not addressed by the terms and conditions of the undertaking 
or by the provisions of this Convention, regard shall be had to generally 
accepted international rules and usages of independent guarantee or stand-by 
letter of credit practice. 


Article 14. Standard of conduct and liability of guarantor/issuer 


(1) In discharging its obligations under the undertaking and this Convention, 
the guarantor/issuer shall act in good faith and exercise reasonable care having 
due regard to generally accepted standards of international practice of 
independent guarantees or stand-by letters of credit. 


(2) A guarantor/issuer may not be exempted from liability for its failure to act 
in good faith or for any grossly negligent conduct. 


Article 15. Demand 


(1) Any demand for payment under the undertaking shall be made in a form 
referred to in paragraph (2) of article 7 and in conformity with the terms and 
conditions of the undertaking. 


(2) Unless otherwise stipulated in the undertaking, the demand and any 
certification or other document required by the undertaking shall be presented, 
within the time that a demand for payment may be made, to the guarantor/issuer 
at the place where the undertaking was issued. 


(3) The beneficiary, when demanding payment, is deemed to certify that the 
demand is not in bad faith and that none of the elements referred to in 
subparagraphs (a), (b) and (c) of paragraph (1) of article 19 are present. 


Article 16. Examination of demand and accompanying documents 


(1) The guarantor/issuer shall examine the demand and any accompanying documents 
in accordance with the standard of conduct referred to in paragraph (1) of 
article 14. In determining whether documents are in facial conformity with the 
terms and conditions of the undertaking, and are consistent with one another, 
the guarantor/issuer shall have due regard to the applicable international 
standard of independent guarantee or stand-by letter of credit practice. 


(2) Unless otherwise stipulated in the undertaking or elsewhere agreed by the 
guarantor/issuer and the beneficiary, the guarantor/issuer shall have reasonable 
time, but not more than seven business days following the day of receipt of the 
demand and any accompanying documents, in which to: 


(a) Examine the demand and any accompanying documents; 

(b) Decide whether or not to pay; 

(c) If the decision is not to pay, issue notice thereof to the beneficiary. 

The notice referred to in subparagraph (c) above shall, unless otherwise 
stipulated in the undertaking or elsewhere agreed by the guarantor/issuer and 
the beneficiary, be made by teletransmission or, if that is not possible, by 
other expeditious means and indicate the reason for the decision not to pay. 


Article 17. Payment 


(1) Subject to article 19, the guarantor/issuer shall pay against a demand made 
in accordance with the provisions of article 15. Following a determination that 
a demand for payment so conforms, payment shall be made promptly, unless the 
undertaking stipulates payment on a deferred basis, in which case payment shall 
be made at the stipulated time. 


(2) Any payment against a demand that is not in accordance with the provisions 
of article 15 does not prejudice the rights of the principal/applicant. 


Article 18. Set-off 


Unless otherwise stipulated in the undertaking or elsewhere agreed by the 
guarantor/issuer and the beneficiary, the guarantor/issuer may discharge the 
payment obligation under the undertaking by availing itself of a right of 
set-off, except with any claim assigned to it by the principal/applicant or the 
instructing party. 


Article 19. Exception to payment obligation 


(1) If it is manifest and clear that: 

(a) Any document is not genuine or has been falsified; 

(b) No payment is due on the basis asserted in the demand and the supporting 
documents; or 

(c) Judging by the type and purpose of the undertaking, the demand has no 
conceivable basis, 

the guarantor/issuer, acting in good faith, has a right, as against the 
beneficiary, to withhold payment. 

(2) For the purposes of subparagraph (c) of paragraph (1) of this article, the 
following are types of situations in which a demand has no conceivable basis: 


(a) The contingency or risk against which the undertaking was designed to 
secure the beneficiary has undoubtedly not materialized; 

(b) The underlying obligation of the principal/applicant has been declared 
invalid by a court or arbitral tribunal, unless the undertaking indicates that 
such contingency falls within the risk to be covered by the undertaking; 

(c) The underlying obligation has undoubtedly been fulfilled to the 
satisfaction of the beneficiary; 

(d) Fulfilment of the underlying obligation has clearly been prevented by 
wilful misconduct of the beneficiary; 

(e) In the case of a demand under a counter-guarantee, the beneficiary of the 
counter-guarantee has made payment in bad faith as guarantor/issuer of the 
undertaking to which the counter-guarantee relates. 

(3) In the circumstances set out in subparagraphs (a), (b) and (c) of paragraph 
(1) of this article, the principal/applicant is entitled to provisional court 
measures in accordance with article 20. 


CHAPTER V. PROVISIONAL COURT MEASURES 


Article 20. Provisional court measures 


(1) Where, on an application by the principal/applicant or the instructing 
party, it is shown that there is a high probability that, with regard to a 
demand made, or expected to be made, by the beneficiary, one of the 
circumstances referred to in subparagraphs (a), (b) and (c) of paragraph (1) of 
article 19 is present, the court, on the basis of immediately available strong 
evidence, may: 


(a) Issue a provisional order to the effect that the beneficiary does not 
receive payment, including an order that the guarantor/issuer hold the amount 
of the undertaking, or 

(b) Issue a provisional order to the effect that the proceeds of the 
undertaking paid to the beneficiary are blocked, taking into account whether 
in the absence of such an order the principal/applicant would be likely to 
suffer serious harm. 




(2) The court, when issuing a provisional order referred to in paragraph (1) of 
this article, may require the person applying therefor to furnish such form of 
security as the court deems appropriate. 


(3) The court may not issue a provisional order of the kind referred to in 
paragraph (1) of this article based on any objection to payment other than those 
referred to in subparagraphs (a), (b) and (c) of paragraph (1) of article 19, or 
use of the undertaking for a criminal purpose. 




CHAPTER VI. CONFLICT OF LAWS 


Article 21. Choice of applicable law 
The undertaking is governed by the law the choice of which is: 
(a) Stipulated in the undertaking or demonstrated by the terms and conditions 
of the undertaking; or 

(b) Agreed elsewhere by the guarantor/issuer and the beneficiary. 



Article 22. Determination of applicable law 


Failing a choice of law in accordance with article 21, the undertaking is 
governed by the law of the State where the guarantor/issuer has that place of 
business at which the undertaking was issued.

Explanatory note by the UNCITRAL secretariat on the 
United Nations Convention on Independent Guarantees and Stand-by Letters of 
Credit*
Introduction 
1. The United Nations Convention on Independent Guarantees and Stand-by Letters 
of Credit was adopted and opened for signature by the General Assembly by its 
resolution 50/48 of 11 December 1995.1 The Convention was prepared by the United 
Nations Commission on International Trade Law (UNCITRAL).2



* This note has been prepared by the secretariat of the United Nations 
Commission on International Trade Law (UNCITRAL) for informational purposes. It 
is not an official commentary on the Convention. 


1 The draft Convention was prepared by the Working Group on 
International Contract Practices at its thirteenth to twenty-third sessions. 
(For the reports of those sessions, see the following volumes of the UNCITRAL 
Yearbook: Yearbook, Volume XXI: 1990 (United Nations publication, Sales No. 
E.91.V.6), document A/CN.9/330; Yearbook, Volume XXII: 1991 (United Nations 
publication, Sales No. E.93.V.2), documents A/CN.9/342 and A/CN.9/345; Yearbook, 
Volume XXIII: 1992 (United Nations publication, Sales No. E.94.V.7), documents

subsequently as a United Nations sales publication), documents A/CN.9/405 and 
A/CN.9/408.) The deliberations of UNCITRAL on the draft Convention are reflected 
in the report on the work of its twenty-eighth session (1995) (Official Records 
of the General Assembly, Fiftieth Session, Supplement No. 17 (A/50/17), paras. 
11-201), annex I of which contains the draft Convention as submitted by the 
Commission to the General Assembly. 


2 UNCITRAL is an intergovernmental body of the General Assembly that 
prepares international commercial law instruments designed to assist the 
international community in modernizing and harmonizing laws dealing with 
international trade. Other legal instruments prepared by UNCITRAL include the 
following: United Nations Convention on Contracts for the International Sale of 
Goods (Official Records of the United Nations Conference on Contracts for the 
International Sale of Goods, Vienna, 10 March-11 April 1980 (United Nations 
publication, Sales No. E.82.V.5), part I); Convention on the Limitation Period 
in the International Sale of Goods, 1974 (New York) (Official Records of the 
United Nations Conference on Prescription (Limitation) in the International Sale 
of Goods, New York, 20 May-14 June 1974 (United Nations publication, Sales No. 
E.74.V.8), part I); United Nations Convention on the Carriage of Goods by Sea, 
1978 (Hamburg) (Official Records of the United Nations Conference on the 
Carriage of Goods by Sea, Hamburg, 6-31 March 1978 (United Nations publication,

Convention on the Liability of Operators of Transport Terminals in International 
Trade (A/CONF.152/13, annex); UNCITRAL Arbitration Rules (Official Records of

57); UNCITRAL Notes on Organizing Arbitral Proceedings ("Yearbook, volume 
XXVIII: 1996" (to be issued subsequently as a United Nations sales publication), 
document A/CN.9/423); UNCITRAL Conciliation Rules (Official Records of the 
General Assembly, Thirty-fifth Session, Supplement No. 17(A/35/17), para. 106);

the General Assembly, Fortieth Session, Supplement No. 17 (A/40/17, annex I); 
United Nations Convention on International Bills of Exchange and International 
Promissory Notes (General Assembly resolution 43/165, annex, of 9 December 
1988); Model Law on International Credit Transfers (1992) (Official Records of 
the General Assembly, Forty-seventh Session, Supplement No. 17(A/47/17); annex 
I); UNCITRAL Model Law on Procurement of Goods, Construction and Services (1994) 
(Official Records of the General Assembly, Forty-ninth Session, Supplement No. 
17 and corrigendum (A/49/17 and Corr.1), annex I); and UNCITRAL Model Law on 
Electronic Commerce (Official Records of the General Assembly, Fifty-first 
Session, Supplement No. 17 (A/51/17), annex I). 



2. The Convention is particularly designed to facilitate the use of independent 
guarantees and stand-by letters of credit where only one or the other of those 
instruments is traditionally in use. The Convention also solidifies recognition 
of common basic principles and characteristics shared by the independent 
guarantee and the stand-by letter of credit. In order to emphasize the common 
umbrella of rules provided for both independent guarantees and stand-by letters 
of credit and to overcome divergences that may exist in terminology, the 
Convention uses the neutral term "undertaking" to refer to both types of 
instruments. 


3. Independent undertakings covered by the Convention are basic tools of 
international commerce. They are used in a variety of situations. For example, 
they are used to secure performance of contractual obligations including 
construction, supply and commercial payment obligations; to secure repayment of 
an advance payment in the event that such repayment is required; to secure a 
winning bidder's obligation to enter into a procurement contract; to ensure 
reimbursement of payment under another undertaking; to support issuance of 
commercial letters of credit and insurance coverage; and to enhance 
creditworthiness of public and private borrowers. Yet familiarity with one or 
the other instrument covered by the Convention is not universal; there is an 
absence of legislative provisions dealing with them, practices concerning the 
two types of instruments have differed in certain respects, and important 
questions confronting users, practitioners and courts in the daily life of these 
instruments are beyond the power of the parties to settle contractually. 


4. By establishing a harmonized set of rules for the two types of instruments 
covered, the Convention will provide greater legal certainty in their use for 
day-to-day commercial transactions, as well as marshal credit for public 
borrowers. Also, by making a single legal regime available to both independent 
guarantees and stand-by letters of credit, the Convention will facilitate the 
issuance of both instruments in combination with each other, for example, the 
issuance of a stand-by letter of credit to support the issuance of a guarantee, 
or the reverse case. The Convention will further facilitate "syndications" of 
lenders, by allowing them to combine more easily both types of instruments. 
Lenders participating in a syndication can spread credit risk among themselves, 
which enables them to extend larger volumes of credit. 


5. The Convention gives legislative support to the autonomy of the parties to 
apply agreed rules of practice such as the Uniform Customs and Practice for 
Documentary Credits (UCP), formulated by the International Chamber of Commerce 
(ICC), or other rules that may evolve to deal specifically with stand-by letters 
of credit, and the Uniform Rules for Demand Guarantees (URDG, also formulated by 
ICC). In addition to being essentially consistent with the solutions found in 
rules of practice, the Convention supplements their operation by dealing with 
issues beyond the scope of such rules. It does so in particular regarding the 
question of fraudulent or abusive demands for payment and judicial remedies in 
such instances. Furthermore, the deference of the Convention to the specific 
terms of independent guarantees and stand-by letters of credit, including any 
rules of practice incorporated therein, enables the Convention to work in tandem 
with rules of practice such as UCP and URDG. 


6. It should be noted that, strictly speaking, an independent guarantee or 
stand-by letter of credit is an undertaking given to a beneficiary. Accordingly, 
the focus of the Convention is on the relationship between the guarantor (in the 
case of an independent guarantee) or the issuer (in the case of a stand-by 
letter of credit) (hereinafter referred to as "guarantor/issuer") and the 
beneficiary. The relationship between the guarantor/issuer and its customer (the 
principal, in the case of an independent guarantee, or the applicant, in the 
case of a stand-by letter of credit, hereinafter referred to as 
"principal/applicant") largely falls outside the scope of the Convention. The 
same may be said of the relationship between a guarantor/issuer and its 
instructing party (the instructing party being, for example, a bank, requesting, 
on behalf of its customer, the guarantor/issuer to issue an independent 
guarantee). 


7. Provided below is a summary of the main features and provisions of the 
Convention. 


I. SCOPE OF APPLICATION 


A. Types of instruments covered 
8. The scope of application of the Convention is confined to instruments of the 
type understood in practice as independent guarantees (referred to as, e.g. 
"demand", "first demand", "simple demand" or "bank" guarantees) or stand-by 
letters of credit (article 2(1)). Those instruments can be covered by the 
umbrella of the Convention because they share a wide area of common use. Both 
types of instruments, which are payable upon presentation of any stipulated 
documents, are used to secure against the possibility that some contingency may 
occur (e.g. a breach of a contract). It may be noted that another major use in 
particular of stand-by letters of credit is as an instrument to effectuate 
payment of mature indebtedness ("financial" or "direct pay" stand-by letters of 
credit). 


9. In the undertakings covered by the Convention the guarantor/issuer promises 
to pay the beneficiary upon a demand for payment. The demand may, depending upon 
the terms of the undertaking, be either a "simple" demand or one having to be 
accompanied by the other documents called for in the guarantee or stand-by 
letter of credit. The guarantor/issuer's obligation to pay is triggered by the 
presentation of a demand for payment in the form, and with any supporting 
documents, as may be required by the independent guarantee or stand-by letter of 
credit. The guarantor/issuer is not called on to investigate the underlying 
transaction, but is merely to determine whether the documentary demand for 
payment conforms on its face to the terms of the guarantee or stand-by letter of 
credit. Because of this characteristic the instruments covered by the Convention 
are referred to commonly as being "independent" and "documentary" in nature. 


10. Reflecting practice, various types of scenarios are envisaged in which an 
undertaking may be given, including at the request of the customer 
("principal/applicant"), on the instruction of another entity or person 
("instructing party") acting at the request of the customer of the instructing 
party, or on behalf of the guarantor/issuer itself (article 2(2)). 


11. Full freedom is given to the parties to exclude completely the coverage of 
the Convention (article 1), with the result that another law becomes applicable. 
Since the Convention, if it is applicable, is to a large extent suppletive 
rather than mandatory, wide breadth is given to exclude or alter the rules of 
the Convention in any given case. 


B. Coverage of counter-guarantees and confirmations 


12. The Convention is designed to include coverage of the "counter-guarantee". A 
counter-guarantee is defined in the Convention (article 6(c)) in the same 
essential terms as the basic notion of "undertaking", namely, as an undertaking 
given to the guarantor/issuer of another undertaking by its instructing party 
and providing for payment upon simple demand or upon demand accompanied by other 
documents, in conformity with the terms and any documentary conditions of the 
undertaking (counter-guarantee). 


13. Apart from this general treatment of counter-guarantees as "undertakings", 
the Convention provides a specific provision on counter-guarantees in the 
context of fraudulent or abusive demands for payment; in that context 
counter-guarantees may raise questions distinct from those raised by other 
undertakings covered by the Convention (see paragraph 48, below). 


14. The Convention also includes in its scope confirmations of undertakings, 
i.e. an undertaking added to that of, and authorized by, the guarantor/issuer. A 
confirmation gives the beneficiary an option of demanding payment from the 
confirmer as an alternative to demanding payment from the guarantor/issuer. By 
requiring authorization of the guarantor/issuer, the Convention does not 
recognize as confirmations "silent" confirmations, i.e. confirmations added 
without the assent of the guarantor/issuer. 


C. Instruments outside scope of Convention 


15. The Convention does not apply to "accessory" or "conditional" guarantees, 
i.e. guarantees in which the payment obligation of the guarantor involves more 
than the mere examination of a documentary demand for payment. Thus, the 
Convention does not annul or affect such other instruments in any way, nor does 
it regulate or discourage their use in any way. Whether it would be preferable 
to use in any given case an independent undertaking of the type covered by the 
Convention, or another type of instrument, would depend on the commercial 
circumstances at play and the particular interests of the parties involved. 


16. Letters of credit other than stand-by letters of credit are not covered by 
the Convention. However, the Convention does recognize a right of parties to 
international letters of credit other than stand-by letters of credit to "opt 
into" the Convention (article 1(2)). That provision has been included in 
particular because the Convention provides a set of rules that parties to 
commercial letters of credit may wish in their own judgement to take advantage 
of, in view of the broad common ground between commercial and stand-by letters 
of credit, and in view of the occasional difficulties in determining whether a 
letter of credit is of a stand-by or commercial variety. 


D. Definition of "independence" 


17. While it is widely recognized that undertakings of the type covered by the 
Convention are "independent", there has been a lack of uniformity 
internationally in the understanding and recognition of that essential 
characteristic. The Convention will promote such uniformity by providing a 
definition of "independence" (article 3). That definition is phrased in terms of 
the undertaking not being dependent upon the existence or validity of the 
underlying transaction, or upon any other undertaking. The latter reference, to 
other undertakings, clarifies the independent nature of a counter-guarantee from 
the guarantee that it relates to and of a confirmation from the stand-by letter 
of credit or independent guarantee that it confirms. 


18. In addition, to fall within the scope of the Convention, an undertaking must 
not be subject to any terms or conditions not appearing in the undertaking. It 
is specified that, to fall within the Convention, an undertaking should not be 
subject to any future, uncertain act or event, with the exception of 
presentation of a demand and other documents by the beneficiary or of any other 
such act or event that falls within the "sphere of operations" of the 
guarantor/issuer. That is in line with the notion that the role of the 
guarantor/issuer in the case of independent undertakings is one of paymaster 
rather than investigator. 


E. "Documentary" character of undertakings covered 


19. As an adjunct to being "independent" from the underlying transaction, the 
undertakings covered by the Convention possess a "documentary" character. This 
means that the duties of the guarantor/issuer when faced with a demand for 
payment are limited to examining the demand for payment and any supporting 
documents to ascertain whether the demand and other documents submitted conform 
"facially" with what is called for under the terms of the independent guarantee 
or stand-by letter of credit. The effect of this rule is that undertakings 
possessing "non-documentary conditions" are outside the scope of the Convention. 
The only conditions which would not have to be documentary in nature would 
relate to acts or events within the sphere of operations of the 
guarantor/issuer. A simple example of the latter would be a determination by the 
guarantor/issuer as to whether a required monetary deposit had been made in a 
designated account maintained with that guarantor/issuer. 


F. Definition of internationality 


20. The Convention limits its application to undertakings that are 
international. Internationality is determined on the basis of the places of 
business, as specified in the undertaking, of any two of the following being in 
different States: guarantor/issuer, beneficiary, principal/applicant, 
instructing party, confirmer (article 4(1)). Special rules are provided for the 
case of an undertaking listing more than one place of business for a party, as 
well as for the case of a party not having a "place of business" as such, but 
only a habitual residence (article 4(2)). 


G. Connecting factors for application of the Convention 


21. The Convention applies to international undertakings in either one of two 
ways. The first way is linked to the location of the guarantor/issuer in a State 
party to the Convention ("Contracting State") (article 1(1)(a)). The second way 
in which the Convention applies is if the rules of private international law 
lead to the application of the law of a Contracting State (article 1(1)(b)). 


22. The Convention provides an additional layer of harmonization of law in this 
field, in that its chapter VI (Conflict of laws, articles 21 and 22) supplies 
the rules to be followed by courts of Contracting States in identifying in any 
given case the law applicable to an independent guarantee or a stand-by letter 
of credit. Those rules apply whether or not in a particular case it turns out 
that the Convention is the applicable substantive law for the independent 
guarantee or stand-by letter of credit in question (see paragraphs 52 and 53, 
below). 


II. INTERPRETATION 


23. The Convention contains a general rule that interpretation of the Convention 
should be with a view to its international character and the need to promote 
uniformity in its application (article 5). In addition, interpretation is to 
have regard for the observance of good faith in international practice. 
Abstracts of any court decisions or arbitral awards applying and interpreting a 
provision of the Convention will be included in the case collection system 
called case law on UNCITRAL texts (CLOUT). 


III. FORM AND CONTENT OF UNDERTAKING 
24. The Convention provides rules on several aspects of the form and content of 
undertakings, as summarized below. 


A. Issuance 


25. On the question of the point of time and place of issuance (i.e. when and 
where the obligations of the guarantor/issuer to the beneficiary become 
operative), the Convention promotes certainty in an area traditionally of some 
uncertainty owing to the existence of differing notions. The Convention rule is 
that issuance occurs when and where the undertaking leaves the sphere of control 
of the guarantor/issuer (e.g. when it is sent to the beneficiary)(article 7(1)). 
In addition, the Convention defines issuance in terms of its practical effect. 
Once issued, the undertaking is available for payment in accordance with its 
terms and is irrevocable. 


26. As is customary in legal texts of UNCITRAL, the Convention establishes a 
flexible and forward-looking form requirement for issuance. By requiring a form 
that preserves a complete record of the text of the undertaking, rather than 
referring to "written" form, the Convention accommodates issuance in a 
non-paper-based medium (e.g. by means of electronic data interchange). It does 
so by referring to issuance in any form that preserves a complete record of the 
text of the undertaking and provides a generally acceptable or specifically 
agreed means of authentication (article 7(2)). 


27. The Convention does not deal with the question of capacity to issue 
undertakings (i.e. who is permitted to be a guarantor/issuer). That question, 
which raises regulatory or other legal implications that differ from country to 
country, is left to national law. 


B. Amendment 
28. Legislative recognition is given by the Convention to the rule of practice 
that amendment of an undertaking requires acceptance by the beneficiary in order 
to take effect, unless it is otherwise stipulated (article 8(3)). The Convention 
takes cognizance of the possibility that an amendment might be authorized in 
advance by the beneficiary. In such cases, the amendment takes effect upon 
issuance (article 8(2)). 


29. In one of the few provisions of the Convention that directly addresses the 
relationship between the principal/applicant and the guarantor/issuer, it is 
made clear that an amendment has no effect on the rights and obligations of the 
principal/applicant, or for that matter of an instructing party or of a 
confirmer, unless such other person consents to the amendment (article 8(4)). 


C. Transfer and assignment 


30. The Convention reflects the distinction drawn in practice between, on the 
one hand, transfer to another person of the original beneficiary's right to 
demand payment and, on the other hand, assignment of the proceeds of the 
undertaking, if payment is made. In the case of assignment of proceeds, as 
contrasted with transfer, the right to demand payment remains with the original 
beneficiary, the assignee being given only the right to receive the proceeds of 
payment if such payment occurs. 


31. Regarding transfer, the Convention endorses the dual requirement, found in 
UCP, that the undertaking itself must state that it is transferable, and that, 
in addition, any actual transfer must be consented to by the guarantor/issuer 
(article 9). The rationale is that a change in the person who is to present the 
demand for payment and any accompanying documents may increase the risk assumed 
by the guarantor/issuer (e.g. if the guarantor/issuer would feel that the 
proposed transferee was less reliable or familiar than the originally designated 
beneficiary). For that reason guarantor/issuers are given the opportunity to 
consent to any given transfer. 


32. Regarding assignment of proceeds, the beneficiary of the undertaking may, 
unless otherwise stipulated in the undertaking or elsewhere agreed, assign the 
proceeds (article 10(1)). If the beneficiary assigns the proceeds and if the 
guarantor/issuer or another person obliged to effect payment has received a 
notice originating from the beneficiary, payment to the assignee discharges the 
obligor, to the extent of its payment, from liability under the undertaking 
(article 10(2)). 


D. Cessation of right to demand payment 


33. The Convention gives legislative effect to notions of cessation of the right 
to demand payment that are widely followed in practice, though not yet 
universally recognized in national laws or judicial precedents. Under the 
Convention (article 11), the events that trigger cessation include: a statement 
by the beneficiary releasing the guarantor/issuer; a termination of the 
undertaking agreed by the guarantor/issuer; full payment of the amount 
stipulated in the undertaking, unless the undertaking provided for automatic 
renewal or increase of the amount available; expiry of the validity period of 
the undertaking. By affirming that the presentation of the demand for payment 
has to occur prior to the expiry of the undertaking, the Convention will help to 
overcome any remaining uncertainty as to that question. 


34. A degree of uncertainty still surrounds, in some jurisdictions, the question 
of the effect of retention of the instrument embodying the undertaking as 
regards definitive cessation of the right to demand payment. The Convention, in 
line with what is regarded widely as the best practice, provides that in no case 
does retention of the instrument prolong the right to demand payment if the 
amount available has already been paid or if the undertaking has expired 
(article 11(2)). Apart from those two contexts, the parties remain free to 
stipulate a requirement of return of the undertaking in order to terminate the 
right to demand payment. 


E. Expiry 


35. The Convention provides (article 12) that the validity period of an 
undertaking expires in the following ways: at the expiry date, which may be a 
fixed date or the last day of a fixed period stipulated in the undertaking; if 
expiry is linked to the occurrence of an act or event, upon presentation of the 
document called for in the undertaking to indicate the occurrence of the act or 
event, or, if no such document is called for, by presentation by the beneficiary 
of certification for that purpose; or after six years from issuance, if no 
expiry date has been stipulated or if a stipulated expiry act or event has not 
occurred. 


IV. RIGHTS, OBLIGATIONS AND DEFENCES 


A. Determination of rights and obligations 


36. The rights and obligations of the guarantor/issuer and the beneficiary are 
determined by the terms and conditions of the undertaking (article 13(1)). 
Express reference is made in the Convention to rules of practice, general 
conditions or usages (e.g. UCP, URDG) to which the undertaking is specifically 
made subject. This is in line with a main purpose of the Convention, to give 
legislative support to the right of commercial parties to incorporate such rules 
of practice, conditions or usages. That approach ensures that the Convention 
will remain a living instrument, sensitive to developments in practice, 
including future revisions of rules of practice such as UCP and URDG and the 
development of other international rules of practice. 


37. The flexible linking of the Convention to the needs and evolving usages and 
standards of commercial practice is also referred to elsewhere in the 
Convention. For example, in the interpretation of the terms and conditions of an 
undertaking and in settling questions not addressed by the Convention, regard is 
to be had to generally accepted international rules and usages of independent 
guarantee or stand-by letter of credit practice (article 13(2)). 


38. Similarly, the standard of conduct of the guarantor/issuer, based on good 
faith and the exercise of reasonable care, is to be defined by reference to 
generally accepted standards of international practice of independent guarantees 
and stand-by letters of credit (article 14(1)). While the Convention leaves open 
the possibility of stipulating a standard somewhat lower than the generally 
applicable standard of care, it clearly prohibits any exemption of the guarantor 
from liability for lack of good faith or gross negligence. 

B. Demand by beneficiary 
39. As regards the beneficiary, the process of demanding and obtaining payment 
involves presenting a demand for payment and any accompanying documents in 
accordance with the terms of the undertaking. In view of the documentary 
character of the demand, the form requirements of the Convention applicable to 
the undertaking itself (see paragraph 27, above) apply to the demand (article 
15(1)). The place of presentation is at the counters of the guarantor/issuer at 
the place of issuance, unless some other place or person is stipulated for 
payment purposes (article 15(2)). 


40. In addition, the Convention provides (article 15(3)) that by virtue of 
making a demand the beneficiary implicitly certifies that the demand is not made 
in bad faith and that none of the circumstances exist that would justify 
non-payment in accordance with the provisions of the Convention on fraudulent or 
abusive demands for payment (see paragraphs 47 and 48, below). 


C. Examination of demand and payment 


41. The duty of the guarantor/issuer is to examine the demand and any 
accompanying documents to determine whether they are in facial conformity with 
the terms and conditions of the undertaking and consistent with one another 
(article 16(1)). That determination is to have due regard to the applicable 
standard of international practice, a formulation that ensures that the 
Convention takes account of developments in practice as regards the notion of 
facial conformity. 


42. In a provision expressly subject to variation by the terms of the 
undertaking, the guarantor/issuer is given a "reasonable time", up to a maximum 
of seven days, to examine the demand and to decide whether to pay (article 
16(2)). Thus, what is deemed a "reasonable time" may well be less than seven 
days, but in no case more than seven days, unless some different period is 
stipulated. This takes into account that the time needed for examination of the 
demand would depend upon the nature of each case (e.g. volume and complexity of 
documents to be examined). 


43. If a decision is taken not to pay, the guarantor/issuer is required to 
promptly so notify the beneficiary, indicating the grounds therefor (article 
16(2)). If the demand is determined to be conforming, payment is to be made 
promptly, or at any later time stipulated in the undertaking. 


44. The Convention recognizes that the guarantor/issuer may, unless the 
undertaking provides otherwise, discharge the payment obligation by exercising a 
right of set-off that is generally available under the applicable law (article 
18). However, the Convention does not recognize any such right of set-off with 
respect to claims assigned by the principal/applicant or instructing party, as 
such a possibility would risk undermining the purpose of the undertaking. 


D. Fraudulent or abusive demands for payment 


45. A main purpose of the Convention is to establish greater uniformity 
internationally in the manner in which guarantor/issuers and courts respond to 
allegations of fraud or abuse in demands for payment under independent 
guarantees and stand-by letters of credit. That has been a particularly 
troublesome and disruptive area in practice because allegations of fraud have a 
tendency to arise when there is a dispute as to the performance of an underlying 
contractual obligation. That difficulty and the resulting uncertainty have been 
compounded further because of the divergent notions and ways with which such 
allegations have been treated both by guarantor/issuers and by courts approached 
for provisional measures to block payment. 

46. The Convention helps to ameliorate the problem by providing an 
internationally agreed general definition of the types of situations in which an 
exception to the obligation to pay against a facially compliant demand would be 
justified (article 19(1)). The definition encompasses fact patterns covered in 
different legal systems by notions such as "fraud" or "abuse of right". The 
definition refers to situations in which it is manifest and clear that any 
document is not genuine or has been falsified, that no payment is due on the 
basis asserted in the demand or that the demand has no conceivable basis. 


47. For additional precision, the Convention provides illustrative examples of 
cases in which a demand would be deemed to have no conceivable basis (article 
19(2); e.g. the underlying obligation has been undoubtedly fulfilled to the 
satisfaction of beneficiary; the fulfilment of the underlying obligation clearly 
has been prevented by wilful misconduct of beneficiary; in the case of a demand 
under a counter-guarantee, the beneficiary of the counter-guarantee has made 
payment in bad faith as guarantor/issuer of the undertaking to which the 
counter-guarantee relates). 


48. The Convention, by entitling but not imposing a duty on the 
guarantor/issuer, as against the beneficiary, to refuse payment when confronted 
with fraud or abuse (article 19(1)), strikes a balance between different 
interests and considerations at play. By allowing discretion to the 
guarantor/issuer acting in good faith, the Convention is sensitive to the 
concern of guarantor/issuers over preserving the commercial reliability of 
undertakings as promises that are independent from underlying transactions. 


49. At the same time, the Convention affirms that the principal/applicant, in the situations referred to, is entitled to provisional court measures to block payment (article 19(3)). This recognizes that it is the proper role of courts, 
and not of guarantors/issuers, to investigate the facts of underlying transactions. Furthermore, the Convention does not annul any rights that the principal/applicant may have in accordance with its contractual relationship with the guarantor/issuer to avoid reimbursement of payment made in contravention of the terms of that contractual relationship. 


V. PROVISIONAL COURT MEASURES 


50. Apart from entitling a principal/applicant or an instructing party to provisional court measures blocking payment or freezing proceeds of an undertaking in the types of cases referred to above, the Convention establishes a standard of proof to be met in order to obtain such provisional measures (article 20(1)). That standard refers to ordering of provisional measures on the basis of immediately available strong evidence of a high probability that the fraudulent or abusive circumstances are present. Reference is also made to 
consideration of whether the principal/applicant would be likely to suffer serious harm in the absence of the provisional measures and to the possibility of the court requiring security to be posted. 


51. While authorizing provisional court measures in the cases concerned, the Convention minimizes the use of judicial procedures to interfere in undertakings by limiting the granting of provisional court measures to those types of cases, 
with one additional type of case. Provisional court orders blocking payment or freezing proceeds are also authorized in the case of use of an undertaking for a criminal purpose (article 20(3)). 


VI. CONFLICT OF LAWS 


52. As noted above (paragraph 22), the Convention contains in chapter VI conflict of law rules to be applied by the courts of Contracting States in order to identify the law applicable to international undertakings as defined in article 2, regardless of whether in any given case the Convention itself would prove to be the applicable law. Those conflict of laws rules recognize a choice of law stipulated in the undertaking or demonstrated by its terms or conditions, 
or agreed elsewhere by the guarantor/issuer and the beneficiary (article 21). 


53. In the absence of a choice of law as described above, the Convention provides for application to the undertaking of the law of the State where the guarantor/issuer has that place of business at which the undertaking was issued 
(article 22). 


VII. FINAL CLAUSES 
54. The final clauses (articles 23-29) contain the usual provisions relating to the Secretary-General of the United Nations as depositary and providing that the Convention is subject to ratification, acceptance or approval by those States that have signed it by 11 December 1997, that it is open to accession by all States that are not signatory States and that the text is equally authentic in Arabic, Chinese, English, French, Russian and Spanish. 
55. In view of its largely suppletive character, as well as of the right of parties to exclude the Convention in its entirety, no reservations are permitted. The Convention enters into force one year from the date of deposit of the fifth instrument of ratification, acceptance, approval or accession.
