What is a notary public — and what does one actually do?
A notary public is an impartial witness commissioned by a state to verify identity, witness signatures, and administer oaths. The stamp doesn't make a document "legal" — it certifies who signed it, and how.
The job in one paragraph
When you sign something important — a deed, a power of attorney, a loan package — the people relying on that document need confidence you really signed it, voluntarily, and knew what you were doing. A notary provides that confidence: they check your ID, watch for coercion or obvious incapacity, complete a notarial certificate, and stamp it with a seal registered with the state. That certificate is what courts and lenders trust.
The main notarial acts
- Acknowledgment — the signer declares they signed a document voluntarily. Used for deeds, mortgages, powers of attorney.
- Jurat / verification on oath — the signer signs in the notary's presence and swears the contents are true. Used for affidavits and sworn statements.
- Oaths and affirmations — administered verbally, with or without a document.
- Copy certification — certifying a copy matches an original; allowed only in some states and only for some documents.
- Signature witnessing — in states that authorize it, certifying the signer signed in front of the notary, without an oath.
What a notary cannot do
A notary is not a lawyer (unless they separately happen to be one). A notary cannot advise you which document you need, draft it, interpret it, or tell you whether to sign. They can't notarize their own signature, act when they benefit from the document, or notarize for a signer who isn't present (in-person or by approved remote technology). In Spanish-speaking communities this matters doubly: a US notary public is not a "notario público" in the Latin-American sense of a licensed legal professional, and most states restrict using that translation in advertising for exactly that reason.
Commission, not license
The credential is a commission — a time-limited state appointment, typically four years, though terms range up to ten (and Louisiana's is lifetime). People search for "notary license," and vendors happily sell against that phrase, but no state issues one. The full requirements — fees, bonds, exams, training — vary a lot by state: here's the national overview, or jump straight to your state's page.
Where notaries work
Most notaries are employees — in banks, law offices, title companies, shipping stores — whose employer covers the commission. Self-employed notaries build income through mobile work, and the busiest niche is the loan signing agent path: notarizing complete mortgage packages for title companies. A growing number also register for remote online notarization, meeting signers by webcam through state-approved platforms.
Notary public FAQ
What is the point of notarization?
Notarization deters fraud. An impartial, state-commissioned witness verifies who signed a document, that they signed willingly, and (for some acts) that they swore its contents are true. Courts, lenders, and agencies rely on the notarial certificate instead of having to track down the signer.
What can a notary NOT do?
A notary cannot give legal advice, prepare or choose documents for you, certify true copies in every state, notarize their own signature, or notarize when they have a financial interest in the document. Non-attorney notaries who drift into legal advice risk unauthorized-practice-of-law penalties — a real issue in immigrant communities where "notario" implies legal authority.
What is the difference between an acknowledgment and a jurat?
In an acknowledgment, the signer declares to the notary that they signed the document voluntarily — the signature can predate the appointment. In a jurat, the signer signs in front of the notary and swears or affirms the contents are true. The certificate wording, and what the notary must witness, differ.
Is a notarized document "legal" or valid everywhere?
Notarization does not make a document legal or enforceable — it evidences who signed it. A document properly notarized in one state is generally accepted in the others; for use abroad you may need an apostille from your state, which authenticates the notary's commission.
Who appoints notaries?
Each state's commissioning authority — the Secretary of State in most states, with exceptions like the Lieutenant Governor in Utah or courts in a few states. The commission is valid for a set term, most commonly four years.
