In what situation is a notary required to refuse notarization?

A notary is required to refuse notarization if the signer appears to be under duress or incapacity. This is crucial because the role of a notary is to ensure that the act of signing is done voluntarily and with full understanding by the signer. If a signer shows signs of pressure or is unable to comprehend the nature and implications of the document they are signing, the notary cannot confirm that the signatures are made willingly and knowingly. This protects the integrity of the notarization process and helps prevent potential fraud or coercion. The notary's responsibility is to not only witness the signature but also to ensure that the signer is acting of their own free will and has the mental capacity to understand the transaction they are undertaking.
