In law, a trust refers to a relationship in which the owner of property gives it to a designated entity, usually described as a trustee. The trustee has a duty to safeguard and use the assets of the trust solely for the benefit of another person or group of persons until distribution, pursuant to the provisions of the trust. 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 an irrevocable trust that is established and funded pursuant to the terms of a deceased person's will. An inter vivos trust is a trust created during the settlor's lifetime.
