Download this Oklahoma Irrevocable Living Trust form if you want a flexible way to plan for the disbursement of your assets after your passing. A trust is flexible, because a grantor can draft the trust in such a way to reflect his or her circumstances and values. A trust is also a private document, so it provides privacy. A trust is continuous, becuase it is a separate entity that is managed during the life of the grantor and after the grantor’s death. The assets put in an irrevocable trust are not meant to be controlled anymore by the grantor other than as set forth in the trust document. Therefore, an irrevocable trust should not be modified or terminated during the life of the grantor.
