A Deed of Trust (also known as a Trust Deed or Trust Agreement) is a legal document used in property law to create a trust by transferring legal title of property from a granter (the owner) to a trustee for the benefit of a beneficiary. The trust is created when the granter conveys the property to the trustee, who then holds legal title to the property for the benefit of the beneficiary. The granter retains the equitable title to the property. There are three types of Deeds of Trust: revocable, irrevocable, and testamentary. A revocable Deed of Trust can be modified or revoked at any time by the granter. An irrevocable Deed of Trust is a permanent arrangement that cannot be modified or revoked by the granter. A testamentary Deed of Trust is created through a will and becomes effective upon the death of the granter.
