What must a notary ensure about the signer's identity?

A notary's primary responsibility is to verify the identity of the signer to ensure the integrity of the notarization process. Valid identification is crucial because it provides evidence of the signer's identity and helps prevent fraud. The notary must check that the ID presented is current, valid, and contains a photograph, signature, and other identifying information that matches the signer.

This requirement is essential in maintaining public trust in notarial acts, as it protects all parties involved by ensuring that the person signing the document is who they claim to be. Valid identification helps establish that the signer has the legal capacity to enter into the transaction or agreement being notarized. Without proper identification, the notarial act could be challenged, potentially leading to legal implications.
