Notary Bulletin How Many Witnesses Are Required To Verify A Signature? By Kelle Clarke on June 24, 2014 in Hotline Tips How many witnesses are required to verify a signer's signature? The question of how many witnesses are required on a document, if any, would be a legal question that is dependent upon the type of document and any applicable state law that sets forth a specific witnessing requirement. Examples would be durable powers of attorney for health care, last wills, mortgages and deeds. Since it is beyond the scope of notarial law, a Notary is not responsible for having such knowledge, and should not offer advice if asked. If this matter becomes a concern for the signer(s) involved, he or she would need to contact the issuing or receiving agency, or an attorney for further assistance. Hotline answers are based on the laws in the state where the question originated and may not reflect the laws of other states. If in doubt, always refer to your own state statutes. –The Editors Kelle Clarke is a Contributing Editor with the National Notary Association. Confronted with a tricky notarization?
