Is it sufficient for a notary to require only one form of identification?

No, it is generally not sufficient for a notary to require only one form of identification. Most jurisdictions recommend or require at least two forms of ID to ensure the identity of the signer is verified accurately. Additionally, the identification should include a photo ID and a document that includes the signer's signature, enhancing the reliability of the identification process. Always check local laws and regulations, as requirements can vary.
