10 M.R.S. §3858: Entry of action; who may defend; bond

The actions must be entered on the docket as follows: the person claiming the lien, as plaintiff, the person alleged to be personally liable, as defendant, and the name or other description of the vessel attached. The owners or mortgagees of the vessel, or any plaintiff in an action in which it is attached for a lien, may appear and defend any action so far as relates to the validity and amount of the lien claim, but the plaintiff may not so defend until the plaintiff gives bond, to the satisfaction of the court, to pay the costs awarded against the plaintiff.
