2.1 The Four Powers of an Ohio Notary

A Closed List of Powers

Ohio notaries do not have open-ended authority. Ohio Revised Code (ORC) Chapter 147 defines a precise set of acts, and House Bill (HB) 315, effective April 4, 2025, reorganized that authority under ORC 147.51. The 30-question proctored Ohio notary exam (passing score 80%, or 24 of 30) leans heavily on knowing exactly what falls inside and outside this list.

Materials commonly summarize the authority as four powers. Note the legal nuance: ORC 147.51 expressly names three acts (oaths/affirmations, acknowledgments, depositions), while the notarial protest power derives from the Uniform Commercial Code (UCC) at ORC 1303.65. The jurat is technically an application of the oath power, not a separate statute, but it is treated as a distinct act in practice.

Power 1: Oaths and Affirmations

An oath is a spoken promise that invokes a higher power — "Do you solemnly swear that the statements in this document are true, so help you God?" An affirmation is the same promise WITHOUT invoking a deity — "Do you affirm, under the penalties of perjury, that these statements are true?"

The two carry identical legal weight. The signer, not the notary, chooses which to use; a notary who refuses to offer an affirmation to a signer with religious or conscientious objections has performed the act improperly. Lying after either exposes the signer to perjury, a criminal offense.

Power 2: Acknowledgments (the workhorse)

In an acknowledgment the signer states they signed voluntarily and are the person named. There is no oath about the truth of the contents. Acknowledgments dominate real-estate work: deeds, mortgages, powers of attorney, and liens.

Powers 3 and 4: Depositions and Protests

A deposition is sworn testimony taken outside court; the notary administers the oath and certifies the record (court reporters who hold a commission usually do this). A notarial protest formally certifies that a negotiable instrument — a check, draft, or promissory note — was presented and dishonored. Both are rare for general notaries but appear on the exam.

What an Ohio Notary CANNOT Do

The exam loves "which is NOT a notary power" questions. Memorize these prohibitions:

• Cannot certify copies of vital records (birth, death, marriage certificates) — only the issuing agency does that
• Cannot give legal advice or draft documents unless also a licensed attorney
• Cannot perform marriages (Ohio notaries lack this authority, unlike some states)
• Cannot notarize their own signature or a document in which they have a financial interest

HB 315 Identification Change

A major 2025 trap: HB 315 eliminated reliance on "satisfactory evidence" (credible witnesses) for in-person notarizations. A notary must identify a signer from personal knowledge or a current government-issued photo ID (or one expired less than three years). Expect this on the exam.

Why the Closed List Matters

The practical reason the list is closed is liability. A notary who strays beyond these acts — for example, certifying that a photocopy is a "true copy" of a passport, or advising a signer that a contract is "legally sound" — is acting without statutory authority and exposes themselves to civil liability and commission revocation. The notary is a neutral, impartial witness to identity and signatures, not a verifier of facts, a lawyer, or a clerk of court.

Internalizing this neutrality answers a large share of scenario questions: when a task is not on the list, the correct response is almost always to decline and refer the person to the appropriate office or professional.

Oaths and Affirmations in Daily Practice

The oath power underlies far more than standalone oath-taking. Every jurat depends on it, every deposition begins with it, and Ohio public officials are sworn in under it. Three practical rules follow:

• The notary must speak the oath or affirmation aloud and the signer must verbally respond — a silent signature is not an oath.
• The notary must offer the affirmation alternative; forcing a religious oath on an objecting signer invalidates the act.
• An oath can be administered without any document at all (for example, swearing in a witness), which is why oaths are a distinct power rather than a subset of the certificate-based acts.

A frequent exam distractor pairs an oath with a document and asks you to label the act. Remember: oath plus a signature in your presence plus a sworn-statement document equals a jurat, while a bare verbal oath with no document is simply administering an oath.

On the Exam

• List the powers cold — and recognize impostor acts (copy certification, marriages)
• Most common act: acknowledgment; most-tested distinction: acknowledgment vs. jurat
• Oath vs. affirmation: equal effect, signer chooses
• HB 315 effective April 4, 2025 reorganized ORC 147.51 and tightened ID rules
