Documentary fraud. This occurs when a commercial party negotiates with a person who turns out to be dishonest and a cheat. A documentary credit may pay for the commercial transaction, for example, where an honest buyer opens a letter of credit based on negotiations between himself and a cheat. The cheat presents forged documents to the advising bank and is paid. The bill of lading features very prominently in documentary fraud because of its very great importance as a document of title. Because of this potential, alternative systems are being developed, such as the use of “sea waybills” and “EDI” or “Electronic Data Interchange” where data about the goods and the mode of their transport are exchanged by electronic means.
