If the lien waiver states all materials supplied as of release date of 4/30/18 must have been paid in full but the subcontractor only supplied the amount paid as of 4/30/18 but all invoices up to 4/30/18 were not paid, does that (if signed) waive lien rights for the material not paid up to the release date? The bottom of the form shows the correct amount paid through the 4/30/18 release date. Does it go by payment through release date or material supplied through release date?
