Unless directed otherwise by the court or by the trust instrument, a successor trustee appointed by the court or by the trust instrument succeeds to all the powers, duties, and discretionary authority given to the predecessor trustee. Upon reasonable request, a successor trustee is entitled to a statement of the accounts of the trust from a predecessor trustee. A successor trustee may accept the account rendered and shall be under no duty to examine the acts or omissions of the predecessor trustee and shall not be liable for failure to seek redress for any act or omission of the predecessor trustee. The trustee of a testamentary trust may accept the account rendered by a personal representative and shall be under no duty to examine the acts or omissions of the predecessor personal representative and shall not be liable for failure to seek redress for any act or omission of the predecessor personal representative.
