What is the term for the termination of a contract as if it never existed?

The term for the termination of a contract as if it never existed is rescission. This legal concept allows a party to void the agreement, returning both sides to their pre-contractual positions. Rescission can occur due to various reasons, including misrepresentation, fraud, undue influence, or a mutual mistake. When a contract is rescinded, it is treated as though it never happened, nullifying any obligations or rights that arose under the agreement.

While cancellation and annulment may seem similar, they have different implications in legal contexts. Cancellation typically refers to ending a contract that is still deemed to have existed but is no longer in effect, while annulment can refer to declaring a contract invalid, but may not fully encompass the idea of treating it as if it never existed. Modification, on the other hand, involves changing the terms of an existing contract rather than terminating it.
