We are a vendor/supplier and are presented with lien waivers very often. Occasionally we are presented with a blank waiver, asking us to complete the dollar amounts, dates etc. then confirm and notarize. As the notary, I refuse to sign if the customer has not completed the amounts/dates/invoice numbers they are requesting the waiver for. I feel we as the vendor are not responsible for completing the information on the waiver, only confirming and agreeing it is correct. Am I correct in this?
