Mass. Gen. Laws ch. 60 § 54
The instrument of taking shall be under the hand and seal of the collector and shall contain a statement of the cause of taking, a substantially accurate description of each parcel of land taken, the name of the person to whom the same was assessed, the amount of the tax thereon, and the incidental expenses and cost to the date of taking. Such an instrument of taking shall not be valid unless recorded within sixty days of the date of taking. If so recorded it shall be prima facie evidence of all facts essential to the validity of the title so taken, whether the taking was made on or before as well as since July first, nineteen hundred and fifteen. Title to the land so taken shall thereupon vest in the town, subject to the right of redemption. Such title shall, until redemption or until the right of redemption is foreclosed as hereinafter provided, be held as security for the repayment of said taxes with all intervening costs, terms imposed for redemption and charges, with interest thereon, and the premises so taken, both before and after either redemption or foreclosure, shall also be subject to and have the benefit of all easements and restrictions lawfully existing in, upon or over said land or appurtenant thereto, and, except as provided in section seventy-seven, all covenants and agreements running with said premises either at law or in equity, when so taken.
