Mass. Gen. Laws ch. 190B § 3-608
Termination of appointment of a personal representative occurs as indicated in sections 3-609 to 3-612, inclusive. Termination ends the right and power pertaining to the office of personal representative as conferred by this code or any will, except that a personal representative, at any time prior to distribution or until restrained or enjoined by court order, may perform acts necessary to protect the estate and may deliver the assets to a successor representative. Termination shall not discharge a personal representative from liability for transactions or omissions occurring before termination, or relieve the personal representative of the duty to preserve assets subject to the personal representative's control, to account therefor and to deliver the assets. Termination shall not affect the jurisdiction of the court over the personal representative, but shall terminate the authority to represent the estate in any pending or future proceeding.
