A civil-law concept defining a rule, doctrine, or procedural mechanism used to resolve private disputes. It applies when its legally specified conditions are satisfied and produces defined consequences in adjudication or settlement. It does not apply where required elements or prerequisites are not met. It materially affects rights, obligations, or available remedies in civil controversies. The concept is generally stable, though statutory and doctrinal refinements may occur over time.

Principle

An accord binds the parties to a substituted obligation; satisfaction occurs when that substitute is performed, thereby extinguishing the original duty if acceptance is bona fide and executed as agreed.

Demonstration

A creditor accepts a lesser monetary payment from a debtor as full settlement of a disputed debt; when the creditor receives and accepts that payment, the prior claim is extinguished by accord and satisfaction.

Misapplication

Treating any agreement to vary performance as accord and satisfaction without clear acceptance risks leaving the original obligation intact, because mere negotiation or partial payment does not automatically satisfy a debt.

Consequence

When properly formed and performed, accord and satisfaction resolves disputes, prevents multiple claims on the same obligation, and replaces the original remedy framework with the agreed substitute performance.

Reversal

If the substitute performance is not accepted or is obtained by fraud, duress, or without consideration where required, the satisfaction fails and the original obligation remains enforceable.

Boundary

Requires a bona fide agreement to accept substituted performance and clear execution; does not apply to unilateral reductions in obligation without mutual assent, nor to statutory rights that cannot be contracted away.

Semantic Tension

Tension arises with doctrines of consideration, estoppel, and statutory consumer protections: some jurisdictions require new consideration for an accord or forbid settlement of certain claims, creating variance in when accord and satisfaction takes effect.

Synthesis

Accord and satisfaction is a two-step settlement device — a binding agreement to accept substituted performance followed by the actual performance that, once accepted, discharges the original contractual obligation.
