Which of the following functions does not fall under the duties of a notary public?

The role of a notary public is primarily focused on providing impartial services to individuals involved in legal documents. Administering oaths, witnessing signatures, and certifying copies of documents are all established responsibilities of notaries.

Administering oaths is a critical duty, as notaries can legally affirm the truth of statements made by individuals in various legal contexts. Witnessing signatures is essential to ensure that the signatories are doing so voluntarily and with an understanding of the document they are signing. Certifying copies of documents offers an assurance that a copy is indeed a true representation of the original, a task that notaries are specifically authorized to perform.

On the other hand, offering legal advice falls outside the scope of a notary's duties. Notaries are meant to serve as impartial witnesses rather than legal advisors. It is important for them to refrain from providing legal opinions or advice, as this could lead to conflicts of interest or the unauthorized practice of law.
