If a notary makes an error in a completed notarial certificate, what is the appropriate way to handle it?

When a notary discovers an error in a certificate, it must be corrected openly and properly, never hidden. Acceptable practice generally involves drawing a single line through the incorrect information so it remains legible, writing the correct information, and initialing and dating the change — or, when appropriate, completing a fresh notarial certificate. Using correction fluid or otherwise concealing an alteration is improper because it can make the document look tampered with and undermines its integrity. Some corrections may require the signer to appear again. Handling errors transparently protects the validity of the notarization and the notary against accusations of fraud or improper alteration.
