As a GC in Florida, we have been paying our subcontractors monthly on a commercial project and receiving lien waivers from them and their suppliers who filed notice to owner. One particular subcontractor has been providing us the lien waivers as well, however we got a call the other day from one of his suppliers who stated they haven't been paid for about 4-5 months. We told them that we have their waivers for each month, but apparently these were forged. We believe we have done all the right things and don't feel we should have to pay this again. Big $$$$$$ We feel the supplier should have notified us after one or at the most two months of non-payment. Surely there is some sort of remedy for us. Thanks for any support or ideas on how to proceed.
