Colorado Code
Article 5 - Letters of Credit
§ 4-5-104. Formal Requirements

A letter of credit, confirmation, advice, transfer, amendment, or cancellation may be issued in any form that is a record and is authenticated (i) by a signature or (ii) in accordance with the agreement of the parties or the standard practice referred to in section 4-5-108 (e).

Editor's note: This section is similar to former § 4-5-104 as it existed prior to 1996.



An authentication agreement may be by system rule, by standard practice, or by direct agreement between the parties. The reference to practice is intended to incorporate future developments in the UCP and other practice rules as well as those that may arise spontaneously in commercial practice.
To be a record sufficient to serve as a letter of credit or other undertaking under this section, data must have a durability consistent with that function. Because consideration is not required for a binding letter of credit or similar undertaking (Section 5-105) yet those undertakings are to be strictly construed (Section 5-108), parties to a letter of credit transaction are especially dependent on the continued availability of the terms and conditions of the letter of credit or other undertaking. By declining to specify any particular medium in which the letter of credit must be established or communicated, Section 5-104 leaves room for future developments.
