Black's Law Dictionary
The conventional mortgage is a contract by which a person binds the whole of his property, or a portion of it only, in favor of another, to secure the execution of some engagement, but without divesting himself of possession. Civ. Code La. art.
3290; Succession of Benjamin, 39 La. Ann. 612, 2 South. 187.
It is distinguished from the "legal" mortgage, which is a privilege which the law alone in certain cases gives to a creditor over the property of his debtor, without stipulation of the parties. This last is very much like a general lien at common law, created by the law rather than by the act of the parties, such as a judgment lien.
