In law a settlor is a person who settles property on trust law for the benefit of beneficiaries. 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.
A trust is the legal relationship created when a person (the settlor) places assets under the control of a person (the trustee) for the benefit of some other person or people (the beneficiaries) or for a specified purpose.
