10. Rights of Mortgagee.—
These depend principally upon the stipulation in the mortgage. He is entitled to have his security made available to the satisfaction of his debt, but, until foreclosure, the ship is subject to many claims which may impair or destroy its value. If seized by admiralty process, the mortgagee may appear and protect his interest, as by taking possession under the usual claim and bond. Seizures or levies under local law are subject to the rights of the owner of a valid mortgage. Generally, the terms of the instrument will provide that, upon any default by the mortgagor or impairment of the security by acts of third parties, the mortgagee may take possession, declare the entire debt due, and foreclose. Where maritime liens affect the security, the mortgagee is entitled to pay them and be subrogated thereto, that is to say, after discharging the liens, he stands in the shoes of the lienors. Where the ship has been arrested and sold by a court of admiralty, and its proceeds are in the registry, he may appear and file an intervening petition for the protection of his interest therein. Where the admiralty disclaims jurisdiction over vessel mortgages, it will pay over surplus proceeds to the mortgagee in preference to the owner or the owner's general creditors. So the mortgagee may answer and contest the claims of the lienors in their proceedings against the ship.
