This is an unofficial version of a Massachusetts General Law.
Section 5-428
(a) Unless otherwise provided in the contract, a conservator is not personally liable on a contract properly entered into in fiduciary capacity in the course of administration of the estate unless the conservator fails to reveal the representative capacity and identify the estate in the contract.
(b) The conservator is not personally liable unless the conservator is personally at fault for either (i) obligations arising from ownership or control of property of the estate, or (ii) torts committed in the course of administration of the estate.
(c) Claims based on (i) contracts entered into by a conservator in fiduciary capacity, (ii) obligations arising from ownership or control of the estate, or (iii) torts committed in the course of administration of the estate, may be asserted against the estate by proceeding against the conservator in fiduciary capacity, whether or not the conservator is personally liable therefor.
(d) Any question of liability between the estate and the conservator personally may be determined in a proceeding for accounting, surcharge, or indemnification, or other appropriate proceeding or action.
