We were a subcontractor on a job. The contractor paid us $7,000 of the $16,000 they owe us. We have been trying to collect the remaining $9,000 for months now. The contractor tells us that the owner hasnt paid him so we have contacted the owner and she claims she has already paid the contractor in full. They both tell us "do what we gotta do to collect"! We have already filed a mechanics lien, so what is our next step?
