Plea in Discharge Law and Legal Definition

Plea in discharge is a form of plea in confession and avoidance in which the defendant admits the existence at one time of a cause of action but alleges that, before the action, the defendant satisfied and discharged plaintiff's claim by payment.

A plea in discharge is one, which admits that a plaintiff had a cause of action, and tends to show that it was discharged by some subsequent or collateral matter. [Nichols v. Cecil, 106 Tenn. 455 (Tenn. 1901)].
