A Letter Notice of Rescission is a formal written document that provides a legal notice of the rescission of a contract or agreement. It is used when one or both of the parties to the contract want to terminate their agreement without having to go through a lengthy legal process. It typically includes the names of the parties, the date the rescission is effective, and the reasons for the rescission. There are two types of Letter Notice of Rescission: unilateral and mutual. A unilateral rescission is when one party to the contract terminates the agreement without the consent of the other party. A mutual rescission is when both parties to the contract mutually agree to terminate the agreement. Both types of rescission must be in writing and signed by both parties in order to be legally binding.
