Which of the following is NOT a duty of a notary public?

Providing legal advice is not a duty of a notary public. The role of a notary is primarily to serve as an impartial witness to the signing of documents, ensuring that the signers are who they claim to be and that they are signing voluntarily and with a sound mind. Notaries are trained to verify identities, administer oaths, and maintain a record of notarial acts through a notarial journal.

While options such as witnessing signatures, requesting identification, and maintaining a notarial journal are all fundamental responsibilities of a notary, offering legal advice falls outside the scope of their duties. Doing so could potentially create conflicts of interest, as notaries must remain neutral and impartial in the transactions they witness.
