In law, a trust is a relationship in which the holder of property (or any other transferable right) gives it to another person or entity who must keep and use it solely for the benefit of another person or group of persons who are termed as 'beneficiary'. In the English common law tradition, the party who entrusts the property is known as the "settlor", the party to whom the property is entrusted is known as the "trustee", the party for whose benefit the property is entrusted is known as the "beneficiary", and the entrusted property itself is known as the "corpus" or "trust property". A testamentary trust is created by a will and arises after the death of the settlor. An inter vivos trust is created during the settlor's lifetime by a trust instrument. A trust may be revocable or irrevocable; an irrevocable trust can be "broken" (revoked) by a judicial proceeding or by consent of the settlor and the beneficiaries.
The trustee is the legal owner of the property in trust, as fiduciary for the beneficiary or beneficiaries who are the equitable owners of the trust property.
