Okla. Stat. tit. 60, § 60-1607.8: Compensation of trustee

A. If the terms of a trust do not specify the trustee's

compensation, a trustee is entitled to compensation that is

reasonable under the circumstances.

B. If the terms of a trust specify the trustee's compensation,

the trustee is entitled to be compensated as specified, but the

court may allow more or less compensation if:

1. The duties of the trustee are substantially different from

those contemplated when the trust was created; or

2. The compensation specified by the terms of the trust would

be unreasonably low or high.
