(a) A provision in the second-trust instrument that is not permitted under this chapter is void to the extent necessary to comply with this chapter.
(b) A provision required by this chapter to be in the second-trust instrument that is not contained in the instrument is deemed to be included in the instrument to the extent necessary to comply with this chapter.
(2) If a trustee or other fiduciary of a second trust determines that subsection (1) applies to a prior exercise of the decanting power, the fiduciary shall take corrective action consistent with the fiduciary's duties.
