Mass. Gen. Laws ch. 156C, § 42

Unless otherwise provided in the operating agreement, if a member who is an individual dies or a court of competent jurisdiction adjudges him to be incompetent to manage his person or his property, the member's executor, administrator, guardian, conservator or other legal representative may exercise all of the member's rights for the purpose of settling his estate or administering his property, including any power under the operating agreement of an assignee to become a member. Unless otherwise provided in an operating agreement, if a member is a corporation, trust or other entity and is dissolved or terminated, the powers of that member may be exercised by its legal representative or successor.
