Notary Bulletin Hotline Tip: How To Notarize A Signature By Mark By NNA Staff on April 04, 2011 in Hotline Tips Occasionally you may encounter an individual who is physically unable to write a signature. In these instances, it still may be possible to perform a notarization as long as the signer can make an ‘X’ or similar mark. This procedure is called signature by mark. With two witnesses present, have the signer make the ‘X’ or similar mark on the document in place of a signature. The witnesses should not be relatives, or have any connection to the transaction. The witnesses then sign their names on the document, and one witness writes the signer’s name next to the mark. Normal certificate wording is still used for the notarization. Only the signer’s name should be included in the certificate. The witnesses’ names and signatures should be included in your journal entry. You also should check your state law for any additional requirements.
