United States agencies mortgagees of record; no cancellation or subordination without notice

Mortgages and the recordation in which any agency or instrumentality of the United States, lending on mortgages secured by real estate is the mortgagee of record, cannot be cancelled, removed from the public records, or in any manner affected, by any sale in any succession, liquidation, insolvency, receivership, or partition proceeding, in any court, unless previous to the application or petition for sale, written notice thereof is given to the agency or instrumentality of the United States, the mortgagee of record. The notice unless waived in writing by the agency or instrumentality of the United States, the mortgagee of record, before or after the sale, must be filed in the proceeding, and a certified copy thereof served on the agency or instrumentality, the mortgagee of record, not less than ten days previous to the filing of the petition or application for the sale. In no event shall the mortgage held by the agency or instrumentality be made secondary to, or ranked or primed by any costs or fees in the proceedings, with the exception of the costs immediately and directly incident to the advertising and selling of the property.
