Uniform Trust Code § 408 (citation from Westlaw) is the model statutory trust provision that validates and renders pet trusts enforceable, if it is adopted by a particular jurisdiction. Section (a) allows for the creation of a pet trust and its termination upon the death of the animal or animals in question. Section (b) allows the court to appoint a person to the trust if no person is appointed in the trust itself. Section (c) regards the amount of money allocated to the purpose of caring for the animal, and allows the court to reduce the amount if excessive and the remainder to be disbursed to the settlor or the settlors successors in interest.
