We're a GC looking to submit a payment app for a stipulated sum project. Our client's LL is letting us provide unconditional lien waivers for progress payments in lieu of copies of invoices paid. Wondering if we could list % complete and/or show that $0 is owed at the time of waiver signature to subcontractors. We want to avoid detailing dollar amounts paid to date. If we get subcontractors to sign a waiver detailing a $0 balance or a % complete, does this remove the LL's mechanic's lien risk for progress payments? Or do waivers need to show the amount paid to date?
