Massachusetts General Laws Part I. Administration of the Government (Ch. 1-182) Ch. 175, § 162

Solicitation or negotiation of policies of insurance that takes place off the premises of an insurance broker, agent or company shall be by a duly licensed broker or agent. Solicitation or negotiation of policies of insurance performed on the premises of an insurance broker, agent or company, may be done by an employee insofar as such solicitation or negotiation is under the immediate direction and general supervision of a duly licensed broker or agent. All binders of insurance and insurance policies shall be signed by a licensed individual or by such person acting under a power of attorney; provided, however, that the provisions of this paragraph shall apply only to the solicitation or negotiation of property or casualty policies of insurance.

Whoever, for compensation, not being an attorney at law acting in the usual course of his profession, directly or indirectly solicits from an insured or the representative of the insured, or performs services pursuant to an agreement, engagement or undertaking to represent the insured in connection with the assessment of damages, negotiation, settlement, appraisal or reference of a loss under a fire insurance policy, homeowners insurance policy, commercial multi-peril insurance policy, business interruption insurance policy, fidelity bond or crime insurance policy, inland or ocean marine insurance policy, or other property damage insurance coverage of any sort, shall be a public insurance adjuster.
