O.C.G.A. § 13-4-101: Elements and requirements of accord and satisfaction generally.

Accord and satisfaction occurs where the parties to an agreement, by a subsequent agreement, have satisfied the former agreement, and the latter agreement has been executed. The execution of a new agreement may itself amount to a satisfaction of the former agreement, where it is so expressly agreed by the parties; and, without such agreement, if the new promise is founded on a new consideration, the taking of it is a satisfaction of the former agreement.
