The Massachusetts Supreme Judicial Court on Friday affirmed a lower court decision in favor of mortgage giant Fannie Mae that removes a legal challenge for borrowers fighting foreclosure.

The state’s top court ruled that a so-called “affidavit of sale” is enough for a lender to prove it has the right to seize a home. The affidavit is used by a lender during the auction process to prove it has complied with foreclosure laws.
