(a) On petition by a trustee, settlor, or beneficiary, a court may modify the administrative or dispositive terms of an irrevocable trust or terminate an irrevocable trust if, because of circumstances not anticipated by the settlor, modification or termination would substantially further the settlor's purposes in creating the trust. (b) Upon termination of a trust under this section, the trust property shall be distributed in accordance with the settlor's probable intention.
