(2) In a directed trust, the terms of the trust grant a person other than a trustee a power over some aspect of the trust's administration.

(3) Under this chapter, this power is called a power of direction, the person that holds the power is called a trust director, a trustee that is subject to the power is called a directed trustee, and the trust is a directed trust.

(4) A directed trustee is required to take reasonable action to comply with a trust director's exercise or nonexercise of a power of direction.
