A successor fiduciary shall have all the rights, powers, duties, and obligations of the predecessor corporate fiduciary. The successor fiduciary shall be deemed named as fiduciary in any writing, including a will, trust, court order, or similar document or instrument that names the predecessor corporate fiduciary as fiduciary, whether executed before or after the successor fiduciary is substituted, unless the writing expressly provides otherwise.
