In trust law, a settlor is a person who settles their property for the benefit of the beneficiary. In some legal systems, a settlor is also referred to as a trustor, or occasionally, a grantor or donor. Where the trust is a testamentary trust, the settlor is usually referred to as the testator. The settlor may also be the trustee of the trust or a third party may be the trustee. In the common law of England and Wales, it has been held, controversially, that where a trustee declares an intention to transfer trust property to a trust of which he is one of several trustees, that is a valid settlement notwithstanding the property is not vested in the other trustees.
