In Levelset, there is a deadline to send an Affidavit of Nonpayment in Goergia if you have provided a lien waiver but still aren't paid. It looks like this document is required 60 days from signing the lien waiver. Do I have to send this document every time I have a progress billing that I'm not paid on but provided a waiver for already? Would I send this document throughout the job, for each unpaid progress billing?
