What should a notary verify before performing notarization?

A notary should verify the signer's understanding of the document before performing notarization because it is essential to ensure that the signer is fully aware of what they are signing and the implications of the document. This verification process helps protect the integrity of the notarization and ensures that the signer is acting voluntarily and without coercion. The notary's role includes confirming that the signer comprehends the content of the document, which is a crucial aspect of safeguarding against fraud and protecting the interests of all parties involved.

While other factors, such as the signer's age, may be relevant in specific contexts (like verifying that they meet legal age requirements), confirming understanding is a fundamental responsibility of the notary in the notarization process. The other options do not pertain directly to the core duties of the notary, which focus on verifying identity and understanding rather than the specifics of document formatting or branding.
