Mass. Gen. Laws ch. 254 § 2B
If, prior to the filing or recording in the registry of deeds and delivery of the copies of the notice of substantial completion described in section two A, any contract subject to the provisions of section two shall have been terminated, the owner shall execute and file or record in the appropriate registry of deeds a notice of termination in substantially the following form:
Notice is hereby given that a written contract dated __________ between __________ as Owner and __________ as Contractor for the erection, alteration, repair or removal of a building, structure or other improvement of real property described below, has been terminated. The lot of land or other interest in real property which is the subject of such contract is described as follows:
The undersigned owner hereby states that he has served written notice of the recording or filing of this notice of termination upon the contractor and every person who has filed or recorded prior to this date a notice of contract under section four of chapter two hundred and fifty-four of the General Laws.
A copy of such notice, indicating the date of filing or recording, shall be mailed by certified mail return receipt requested by the owner to every person who has filed or recorded a notice of contract under section four and to the contractor. Upon receipt of such notice from the owner, the contractor shall deliver a copy of such notice to every person who has entered into a written contract directly with the contractor or who has given to the contractor written notice of identification in accordance with said section four.
The failure of the owner or contractor to give notice of the filing or recording of the notice of termination to those persons so entitled shall not prejudice the rights of third parties who rely upon said notice of termination in good faith and without actual knowledge of such failure of notice.
