Novation is the substitution of a new debt or obligation for an existing one. Novation is a contract, consisting of two stipulations, one to extinguish an existing obligation; the other to substitute a new one in its place. Civ. Code La. art. 2185. The term was originally a technical term Of the civil law, but is now in very general use in English and American jurisprudence. In the civil law, there are three kinds of novation: (1) Where the debtor and creditor remain the same, but a new debt takes the place of the old one; (2) where the debt remains the same, but a new debtor is substituted; (3) where the debt and debtor remain, but a new creditor is substituted. Adams v. Power, 48 Miss. 451.
