We provided services that we were unpaid for. The work was done in NYC for 2 residences. Our business partner who is the licensed Master Plumber in NYC did the work on our behalf. We have in our possession signed contracts which are payable to our company and paid our business partner from our monies for the work that was done. We have not received payment from the firm which hired us and also have outstanding balances on work that was billed directly to homeowner. If we are not a licensed GC in NYC but the plumber who performed the work is licensed in NYC are we still able to place a mechanics lien on the two residences the work was performed in order to attempt to collect the unpaid balances?
