§ 1313. Permissible defendants. Any person who is liable to the

plaintiff for payment of the debt secured by the mortgage may be made a

defendant in the action. The state may be made a party defendant to an

an interest in or a lien on the property subsequent to the lien of the

mortgage sought to be foreclosed in said action, in the same manner as a

private person.
