Which contract concept involves an agreement to substitute performance and its completion to settle a dispute?

• A. Gratuitous promise
• B. Exculpatory clause
• C. Valuable consideration
• D. Accord and satisfaction

Answer: (D)

Accord and satisfaction involves a dispute over what is owed, and the parties agree to substitute a different performance for the original obligation to settle that dispute. The accord is the agreement to accept this substitute, and the satisfaction is the actual completion of that substituted performance. Once the substituted performance is completed, the original obligation is discharged.

This concept is used when the claim is unliquidated or disputed, such as agreeing to accept a lesser amount or a different form of payment as full settlement. If the substituted performance isn’t carried out, the original obligation can still remain enforceable.

The other choices don’t fit because: a gratuitous promise lacks the consideration needed to form a binding contract; an exculpatory clause shifts liability rather than substituting one performance for another to settle a dispute; valuable consideration refers to what is exchanged to form a contract, not the mechanism of settling a dispute by substituting performance.
