Irrevocable trust
Irrevocable trust: A trust that the settlor cannot cancel or change on their own after it is created. However, it can sometimes be changed or ended with the consent of the settlor and all beneficiaries, or by a court (Uniform Trust Code § 411).

They show how judges apply the term today. Also, remember that state law can differ from federal law. For that reason, use our state procedures guide to find your state’s rules.
