I receive several California Conditional Waiver and Release on Progress Payment forms and they all seem to be filled out differently. For example, we are currently receiving waivers for May progress payments. The waiver lists the "Through Date" as May 31, 2019. The sub-contractor's invoices for May 2019 total $20,000. There are also previous invoices that have not been paid that total $10,000. Should the "Amount of Check" be $20,000 (for May only) or $30,000 (to include all outstanding invoices) even if the previous unpaid invoices are listed under EXCEPTIONS?
