Mass. Gen. Laws ch. 152 § 39
The compensation payable in case of the death of the injured employee shall be paid to his legal representative; or, if he has no legal representative, to his dependents; or, if he leaves no dependents, to the persons to whom payment of the expenses for the last sickness and burial is due. If payment is made to the legal representative of the deceased employee, it shall be paid by him to the dependents or other persons entitled thereto under this chapter. When the appointment of a legal representative of a deceased employee or dependent, or the appointment of a guardian or conservator of an employee or dependent who is a minor or is otherwise legally incapacitated, is required to comply with this chapter, the insurer shall furnish or pay for legal services rendered in connection with the appointment of such legal representative, guardian or conservator or in connection with his duties, and shall pay the necessary disbursements for such appointment, the necessary expenses of such legal representative, guardian or conservator, and reasonable compensation to him for time necessarily spent in complying therewith. Said payments shall be in addition to sums paid for compensation.
