N.M. Stat. § 55-5-103
Scope.
(a) This article applies to letters of credit and to certain rights and obligations arising
out of transactions involving letters of credit.
(b) The statement of a rule in this article does not by itself require, imply or negate
application of the same or a different rule to a situation not provided for, or to a person
not specified, in this article.
(c) With the exception of this subsection, Subsections (a) and (d) of this section,
Paragraphs (9) and (10) of Subsection (a) of Section 55-5-102 NMSA 1978, Subsection
(d) of Section 55-5-106 NMSA 1978 and Subsection (d) of Section 55-5-114 NMSA
1978, and except to the extent prohibited in Section 55-1-302 NMSA 1978 and
Subsection (d) of Section 55-5-117 NMSA 1978, the effect of this article may be varied
by agreement or by a provision stated or incorporated by reference in an undertaking. A
term in an agreement or undertaking generally excusing liability or generally limiting
remedies for failure to perform obligations is not sufficient to vary obligations prescribed
by this article.
(d) Rights and obligations of an issuer to a beneficiary or a nominated person under
a letter of credit are independent of the existence, performance or nonperformance of a
contract or arrangement out of which the letter of credit arises or which underlies it,
including contracts or arrangements between the issuer and the applicant and between
the applicant and the beneficiary.
