studying about legal nature of forfaiting comparing with other financial methods

In international trade, there are several financing methods which help exporters and ‎importers for buying and selling goods. Forfaiting is one of these methods. It is a ‎financing method in which forfaiter purchases exporters' deferred receivables based on ‎discounting rate and without recourse payment. Type of document, as an evidence of the payment, has an essential role in this commercial ‎contract, since the nature and performance of forfaiting depend on type of document of ‎receivables. While exporter and forfaiter are parties to the financing contract, it isalso  applicable against the debtor, and forfaiter can pursuit importer on due date for the payment claim‏. ‏ Moreover, although forfaiting may be trilateral between forfaiter, exporter and importer ‎in which debtor transfers his debt to financial institutions, in the traditional type of forfaiting, ‎exporter assigns his receivables to the forfaiter. This contract is similar to discounting, ‎negotiation, novation, assignment, selling of debt or the payment claim. It seems that the sale of debt is ‎the most appropriate for this new financing method‏. If commercial papers are used as evidence of the payment, rules of negotiation ‎will be governed in this contract. ‏
