Mass. Gen. Laws ch. 60 § 53
If a tax on land is not paid within fourteen days after demand therefor and remains unpaid at the date of taking, the collector may take such land for the town, first giving fourteen days' notice of his intention to exercise such power of taking, which notice may be served in the manner required by law for the service of subpoenas on witnesses in civil cases or may be published, and shall conform to the requirements of section forty. He shall also, fourteen days before the taking, post a notice so conforming in two or more convenient and public places.
Whenever the collector of taxes of a city or town shall have taken land therein he may, in the name and on behalf of said city or town, take immediate possession of such land and, until the tax title so acquired is redeemed, collect the rent and other income from such land, which rent and income, after the payment therefrom of all necessary expenses in the care, repair and management of such land, shall be applied on account of the taxes, assessments, rates, charges, interest and costs due said city or town on said land, with any balance remaining being paid to the person otherwise entitled thereto. Upon petition of any person having a right to redeem such tax title, the superior court for the county within which the land lies, if it adjudges justice and the circumstances so warrant, may, upon such terms as it shall deem equitable, enjoin a taking of possession under this section or command the surrender of a possession taken.
Neither said city or town nor any of its officers, agents or employees shall be liable or accountable to the owner or to any other person having an interest in such land for failure to collect rent or other income therefrom; and neither said city or town nor any of its officers, agents or employees shall be liable for injury or damage caused by the possession of land under this section to such land or to the person or property of any person.
