Iowa Code § 633A.2105: Honorary trusts — trusts for pets.

2. A trust for the care of an animal living at the settlor’s death is valid. The trust terminates when no living animal is covered by its terms.

3. A portion of the property of a trust authorized by this section shall not be converted to any use other than its intended use unless the terms of the trust so provide or the court determines that the value of the trust property substantially exceeds the amount required.
