A notary public is a state-commissioned official who witnesses signatures on important documents, verifies that the signers are who they say they are, and confirms they’re signing willingly and knowingly. The role exists to deter fraud and give courts, banks, and government offices a reason to trust that a signed document is genuine. Every state writes its own rules, but the core job is the same across the country.
What a Notary Public Does
A notary acts as an impartial witness at the signing of a document. The work is strictly ministerial, which means the notary follows a procedure set by state law rather than exercising personal judgment about what the document says or what it will do. The notary checks who you are, confirms you’re acting voluntarily, applies an official seal, and moves on. They have no stake in the transaction and take no side in it.
In most states, the Secretary of State issues notary commissions. A few states hand that authority to the governor or another office. Commissions usually last four to five years and can be renewed. Every notary receives an official seal and files a signature specimen with the commissioning agency, and that seal on a document is what signals to a court or a bank that someone verified identities and followed the required steps.
Documents That Typically Require a Notary
Most everyday paperwork doesn’t need a notary. The documents that do tend to involve significant money, property, or legal authority.
Real estate transactions are the most common trigger. Deeds, mortgage documents, and deeds of trust almost always have to be notarized before a county office will record them. Powers of attorney are another frequent category, because courts and financial institutions want assurance that the person handing over legal or financial authority actually signed and understood the document. Affidavits and sworn statements need notarization because the signer takes an oath that the contents are truthful. Advance health care directives, certain business formation documents, and many contracts round out the usual list.
If you’re closing on a home loan, expect a notary at the signing table. Loan signing agents are notaries with extra training in mortgage paperwork. They witness your signatures and return the package to the lender or title company. They still can’t explain the legal terms to you or advise you on the deal.
What to Expect at a Notary Appointment
Every notarization follows the same basic sequence regardless of the document type.
Proving Who You Are
The notary has to confirm your identity before anything else. Usually that means handing over a current government-issued photo ID such as a driver’s license or passport. If you don’t have acceptable ID, many states allow a credible identifying witness to vouch for you. A credible witness personally knows you, has no financial interest in the transaction, and takes an oath before the notary confirming your identity. Some states require one credible witness who is personally known to the notary; others accept two witnesses who present their own valid IDs.
Showing You’re Signing Willingly
After checking ID, the notary looks at whether you’re acting voluntarily and have a basic grasp of what the document does. This isn’t a mental competency exam, but the notary is watching for red flags. If a signer appears confused, disoriented, or pressured by someone else in the room, the notary should stop.
The Seal, the Certificate, and the Journal
Once satisfied, the notary fills out the notarial certificate attached to the document, applies the official seal, and signs. They also record the transaction in an official journal: date and approximate time, type of notarial act, your name and address, and how your identity was verified. Many states require notaries to keep these journals for ten years.
The Different Notarial Acts
“Notarization” is a general term that covers several different acts. Which one you need depends on the document.
- Acknowledgment. You appear before the notary and declare that you signed the document voluntarily and for its intended purpose. You don’t have to sign in front of the notary; you just have to acknowledge having signed. This is the most common act and is used for deeds, powers of attorney, and many contracts.
- Jurat. You swear an oath or make a solemn affirmation that the statements in the document are true, and you sign in the notary’s presence. Jurats appear on affidavits and other sworn statements, where false contents can expose the signer to perjury charges.
- Oath or affirmation. The notary administers a verbal oath or affirmation without an attached written document. This is used for swearing in witnesses, public officials, and others pledging truthfulness or faithful performance.
- Copy certification. Where state law permits it, a notary can certify that a photocopy is a complete and accurate reproduction of an original. This does not cover vital records such as birth or death certificates, which only the issuing agency can certify. A few states don’t authorize copy certification at all.
What a Notary Cannot Do
Unless the notary is also a licensed attorney, they can’t draft legal documents, tell you which document you need, or explain what signing one will mean for you. Even telling a signer what a particular contract clause means can cross into the unauthorized practice of law. This is the single most common way notaries get into trouble.
There are a few other hard limits worth knowing. A notary cannot certify copies of vital records like birth, death, or marriage certificates — those come only from the government office that issued them. A notary’s commission is geographically limited to the state that granted it, so a notarial act performed outside that state is unauthorized, even if the document will be used back home. And a notary cannot notarize a document in which they’re named as a party, have a financial stake, or are serving a spouse, parent, or child.
Foreign-language documents are a gray area. Most states don’t flatly ban notarizing a document written in another language, but the notarial certificate itself has to be completed in English (or another language the notary reads and writes), and the notary needs to communicate directly with the signer in a shared language. Relying on a third-party interpreter is risky, and only Arizona expressly authorizes notaries to use one. The English word “notary” and the Spanish “notario” describe very different roles in different legal systems, and a U.S. notary who holds no law license cannot offer the broader legal services that a notario provides in some other countries.
When a Notary Will Refuse
Refusing is sometimes required. A notary should decline if you can’t be properly identified, appear to lack the capacity to understand the document, seem to be acting under coercion, or aren’t physically present when the state doesn’t permit remote notarization for that transaction. Blank spaces in the document that could be filled in later, or a missing notarial certificate when the signer can’t specify which act is needed, are also valid reasons. If the notary suspects the transaction is fraudulent, deceptive, or illegal, they must refuse regardless of pressure.
A notary cannot refuse service based on your race, religion, nationality, gender, age, or disability. Disagreeing with the content of the document is also not a legitimate reason to turn you away. The job is to verify identity and willingness, not to judge the deal.
Remote Online Notarization
Notaries and signers used to have to be in the same room. Virginia changed that in 2011 by authorizing remote online notarization, which lets the personal appearance happen through live audio-video technology. Nearly all states now permit it.1National Association of Secretaries of State. Remote Electronic Notarization
Remote sessions usually require tighter identity verification than in-person ones. Beyond showing an ID on camera, the signer typically has to pass knowledge-based authentication questions drawn from personal credit and public records, and the ID itself gets analyzed for signs of tampering.1National Association of Secretaries of State. Remote Electronic Notarization The session is recorded and stored. A federal bill, the SECURE Notarization Act, has been introduced in Congress to standardize interstate recognition of remote notarizations, but as of mid-2025 it remained pending.2Congress.gov.

Typical Fees
Most states cap what a notary can charge per act. For in-person acknowledgments and jurats, the maximum usually falls somewhere between $2 and $15 per signature. A handful of states set no statutory cap. Remote online notarizations tend to carry higher ceilings, often around $25 per signature, and some states allow a separate technology fee on top of the base charge. Notaries can always charge less than the cap or waive the fee, but they can’t charge more.
