Mass. Gen. Laws ch. 236, § 24: Validity of levy as against subsequent attaching creditors and purchasers

Section 24. If the execution and return are not recorded in the registry of deeds within three months as aforesaid, the levy shall be void as against a creditor who has attached the same land or taken it on execution without notice of such levy, and also as against a purchaser in good faith for value and without such notice; but if such execution and return are recorded after the expiration of the three months, the levy shall be valid and effectual as against a conveyance, attachment or levy made after such recording.
