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.
