Rule 11 agreements are terms that a party can agree on and have the same affect as a court order. So long as the agreement satisfies the requirements of Texas Civil Procedure 11, these agreements are enforceable.
Can I get out of a Rule 11 agreement that I entered into by mistake?
There are certain situations where these agreements can be considered void; one way to make the agreement void is by showing the agreement was made by mistake. In the Dallas 5th District Court of Appeals case, In the Interest of A.B. & D.Y, a mother wanted to void a Rule 11 agreement that she had made because she claimed the agreement was made by mistake. In this case, the court explained, “mutual mistake is an affirmative defense, that states when the parties to an agreement have contracted under a misconception or ignorance of a material fact, the agreement will be avoided.” When someone wants to void a Rule 11 agreement based on a mistake, it is up to that person to prove to the court that the agreement should be voided.
