(Civ. Law) The act or contract by which property is hypothecated; a right which a creditor has in or to the property of his debtor, in virtue of which he may cause it to be sold and the price appropriated in payment of his debt. This is a right in the thing, or jus in re. "There are but few cases, if any, in our law, where an hypothecation, in the strict sense of the Roman law, exists; that is a pledge without possession by the pledgee." Note: In the modern civil law, this contract has no application to movable property, not even to ships, to which and their cargoes it is most frequently applied in England and America. See Hypothecate.
