Non est factum – latin for "it is not my deed" – is a doctrine in contract law that allows a signing party to escape performance of the agreement. A claim of non est factum means that the signature on the contract was signed by mistake, without knowledge of its meaning, but was not done so negligently. A successful plea would void the contract.
