This is an unofficial version of a Massachusetts General Law.
Section 5-419
(a) The appointment of a conservator vests in the conservator title as fiduciary to all property, or to the part thereof specified in the order, of the protected person, held at the time of appointment or thereafter acquired. An order vesting title to only a part of the property of the protected person creates a conservatorship limited to assets specified in the order.
(b) Except as otherwise provided herein, the interest of the protected person in property vested in a conservator by this section is not transferable or assignable by the protected person. An attempted transfer or assignment by the protected person, though ineffective to affect property rights, may generate a claim for restitution or damage.
