I'm supplier. Material on 12/19/19. And it's installed on driveway The homeowner is State Trooper so we can not search who owns the house. He said he already pay the contractor, so it's not his problem. The contractor disappear and don't pay us either In this case, can we file mechanic lien? We come to State Trooper's house on 02/14, he said he never sign owner name when he received the mail so we can't file lien, he said he aked the lawyer already. I sound like homeowner and contractor try to not paid. What should we do?
