Notary Bulletin Hotline Tip: Can I Backdate A Mortgage Document? By NNA Staff on December 07, 2011 in Hotline Tips I recently notarized a mortgage signing in which one of the documents sent to the lender was misplaced. The signing agency has asked me to contact the signers, re-execute the document and notarize it for a past date, or, in other words, post-date the notarization. Can I do this? – P.D., Denver, Colorado Since you are performing a new notarization, you can only input the date that you are actually notarizing the new document, not a date that came before. You should never back-date or post-date a notarial certificate; doing so is a deceptive practice and is not allowed in any state. Confronted with a tricky notarization? Unsure how to proceed?
