Ohio Rev. Code § 5804.12: Judicial action due to change of circumstances.

(A) The court may modify the administrative or dispositive terms of a trust or terminate the trust if because of circumstances not anticipated by the settlor modification or termination will further the purposes of the trust. To the extent practicable, the court shall make the modification in accordance with the settlor's probable intention.

(B) The court may modify the administrative terms of a trust if continuation of the trust on its existing terms would be impracticable or impair the trust's administration.

(C) Upon termination of a trust under this section, the trustee shall distribute the trust property in a manner consistent with the purposes of the trust.

(D) The court may modify or interpret the terms of a trust, including, but not limited to, a charitable trust or a trust having as a beneficiary an organization with one or more purposes that are described in division (A) of section 5804.05 of the Revised Code, that refer to the federal estate tax, federal generation-skipping transfer tax, or Ohio estate tax, or that contain a division of property based on the imposition or amount of one or more of those taxes, to give effect to the intent of the settlor.
