In the small claims court you can ask for an order removing the lien and an adjudication
that you do not owe the plumber anything, but that the plumber owes you.
2) Attempt to negotiate with the plumber. 3) See if the plumber would engage in a process like mediation in which an independent person will attempt to resolve the case.
4) Hire an attorney and sue the plumber in district court
. In district court, if you prevail, you can get an order removing the plumber's lien. Good luck.
