Antichresis
Antichresis, under civil law and Roman law, is a contract whereby a debtor pledges (i.e., conveys possession of but not title to) real property to a creditor, allowing the use and occupation of the pledged property, in lieu of interest on the loan. Historically, antichresis was used in Ancient Mesopotamia (Akkad, Assyria, Babylonia) and by the Greeks and the Romans and it is still widely used in Bolivia.
