The legal act or process of disaffirming something, such as a court decision or contract.
From disaffirm + -ance (a suffix forming nouns from verbs). Developed in English legal terminology, particularly in contract law and appellate procedure.
Disaffirmance is the noun form that lawyers use when they're formally rejecting a previous agreement or ruling—it's the official 'undo' button in the legal world, used especially when a minor wants to back out of a contract they signed.
