When a mortgage constituted to secure a loan has been divided among several properties and part of the loan with which one of them was encumbered is paid, partial cancellation of the mortgage on it may be demanded by the interested party.\nIf a portion of the loan paid could be applied to the release of one or more of the encumbered properties because it is not less than the amount of the special liability of each one, the debtor shall select the one that is to be released.\nHistory —Mortgage Law, 1979, § 175.
