definite or definitely ascertainable beneficiary or for a

noncharitable but otherwise valid purpose to be selected by the

2. A trust authorized by this section may be enforced by a

person appointed in the terms of the trust or, if no person is so

appointed, by a person appointed by the court; and

be distributed to the settlor, if then living, otherwise to the

settlor's successors in interest.
