Accord and Satisfaction

Definition

An agreement (accord) between two contracting parties to accept alternate performance to discharge a preexisting duty between them and the subsequent performance (satisfaction) of that agreement. An accord and satisfaction differs from a modification in that a modification immediately discharges a preexisting duty, whereas an accord and satisfaction does not discharge a preexisting duty until the agreed upon, alternate performance occurs.
