Okla. Stat. tit. 60, § 60-1604.11: Modification or termination because of unanticipated

circumstances or inability to administer trust effectively.

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

modification must be made 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 wasteful 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.
