broadest sense is a natural person or other legal entity who receives money or other benefits from a benefactor. Note that under the scheme of letters of credit, banks are neither benefactors of sellers nor benefactors of buyers and the seller receives no money in gratuity mode. Thus is possible that a “letter of credit” was one of those contracts that needed to be masked to disguise the “consideration or privity requirement”. As a result, this kind of arrangement would make letter of credit to be enforceable under the action assumpsit because of its promissory connotation. A few countries have created statutes in relation to letters of credit. For example, most jurisdictions in the United States (U.S.) have adopted Article 5 of the Uniform Commercial Code (UCC). These statutes are designed to work with the rules of market practice including UCP and ISP98. These rules of practice are incorporated into the transaction by agreement of the parties. The latest version of the UCP is the UCP600 effective July 1, 2007. Since the UCP are not laws, parties have to include them into their arrangements as normal contractual provisions. However, they still form a substantial part of market practice and underpin Financial law crucially. National laws Germany Bürgerliches Gesetzbuch, the German civil code, does not directly address letters of credit. German case law indicates that the relationship between the issuing bank and customer is a contract for execution of a transaction, while the relationship between the issuing bank and the beneficiary is a promise of a debt. Switzerland The Swiss Civil Code of 1911 did not directly address letters of credit, which were still rare in the country at the time. Courts eventually dealt with the device by treating it as a hybrid of a mandate (Auftrag) and authorization-to-pay contract (Anweisung). United States Letters of credit came into general domestic use in the United States during World War I, although they had been used in American foreign trade for some time prior. The state of New York has historically had the most substantial and consistent body of case law in the United States with regard to letters of credit, due to the prominence of New York banks in international trade. The New York Bankers Commercial Credit Conference of 1920 provided the first set of voluntary L/C regulations for major banks in the United States, but these banks transitioned to the international
