Administering oaths and affirmations is a core notarial power, not an incidental one, and it extends to oaths of office for public officials. The power exists because an oath's validity depends on it being administered by someone authorised to do so, and the state confers that authority on notaries precisely so that oaths can be taken without requiring a judicial officer. A newly elected school board member therefore may take the oath of office before a notary, and the notary administers it in the same manner as any other oath — with the person present, aware of what they are undertaking, and giving an affirmative response. There is often a written oath of office to be signed and filed, in which case the notary completes the appropriate certificate and records the act in the journal. What the notary must not do is advise on whether the oath is required, when it must be taken, or what its wording should be, since those are questions of law for the office concerned.
