HONORARY TRUSTS FOR PETS

S 7-6.1 Honorary trusts for pets
(a) A trust for the care of a designated domestic or pet animal is valid. The intended use of the principal or income may be enforced by an individual designated for that purpose in the trust instrument or, if none, by an individual appointed by a court upon application to it by an individual, or by a trustee. Such trust shall terminate when no living animal is covered by the trust, or at the end of twenty-one years, whichever occurs earlier.
(b) Except as expressly provided otherwise in the trust instrument, no portion of the principal or income may be converted to the use of the trustee or to any use other than for the benefit of a covered animal.
(c) Upon termination, the trustee shall transfer the unexpended trust property as directed in the trust instrument or, if there are no such directions in the trust instrument, the property shall pass to the estate of the grantor.
(d) A court may reduce the amount of the property transferred if it determines that amount substantially exceeds the amount required for the intended use. The amount of the reduction, if any, passes as unexpended trust property pursuant to paragraph (c) of this section.
(e) If no trustee is designated or no designated trustee is willing or able to serve, a court shall appoint a trustee and may make such other orders and determinations as are advisable to carry out the intent of the transferor and the purpose of this section.
