Utah Code § 75B-3-112

The terms of a trust may relieve a cotrustee from duty and liability with respect to another cotrustee's exercise or nonexercise of a power of the other cotrustee to the same extent that, in a directed trust, a directed trustee is relieved from duty and liability with respect to a trust director's power of direction under Sections 75B-3-109 through 75B-3-111.
