Since the documentary credits were the most widely used in the
field of international commerce, as to ensure the execution of
international sales contracts, the question, of the legal nature of the

important.

and documentary collection, and between the transferable
documentary credit and the other similar operations as assignment
of right, back to back credit and other specific credits.
