(a) Without authorization by a court, a trustee may exercise the powers conferred by the terms of the trust and, except as limited by the terms of the trust, the powers conferred by this chapter.
(b) This chapter does not affect the power of a court to (1) relieve a trustee from provisions contained in the terms of the trust that restrict the exercise of powers;
(2) confer on a trustee additional powers, whether or not the powers are authorized by the terms of the trust; or
(3) restrict the exercise of a power otherwise given to the trustee by the terms of the trust or this chapter.
(c) The grant of a power to a trustee, whether under the terms of the trust, this chapter, or a court, does not alone govern the exercise of the power.
