Massachusetts General Laws Part II. Real and Personal Property and Domestic Relations (Ch. 183-210) Ch. 198, § 10A

A person shall be deemed to have given a preference if, being insolvent, he has, within four months before his decease, procured or suffered a judgment to be entered against himself in favor of any person, or made a transfer of any of his property, and the effect of the enforcement of such judgment or transfer will be to enable any one of his creditors to obtain a greater percentage of his debt than any other of such creditors of the same class. Where the preference consists in a transfer, such period of four months shall not expire until four months after the date of the recording or registering of the transfer, if by law such recording or registering is required.
