Like a Revocable Living Trust, an Irrevocable Living Trust helps avoid the costs and publicity of probate. However, an Irrevocable Living Trust cannot be revoked after its creation; except upon the consent of all the beneficiaries, the grantor, the trustee, and usually a judge. There are many different types of irrevocable trusts; two of the more common are the Life Insurance Trust (ILIT) and Charitable Trusts.
