A notary public is a state-commissioned official who acts as an impartial witness when you sign important documents, verifying your identity, confirming you’re signing willingly, and completing a certificate that courts, agencies, and financial institutions can rely on as proof the signing was genuine. The role is narrow on purpose. A notary is not a lawyer, does not read your document for you, and does not vouch for whether its contents are a good idea. What a notary does is add a layer of independent verification that deters fraud and makes a document legally reliable.
What a Notary Does at the Appointment
The job comes down to a short, specific sequence, and each step has to happen for the notarization to hold up.
You appear before the notary in person. A notary cannot notarize a document unless the signer is physically present, either in the same room or, where allowed, on a live audio-video connection. Bring the document unsigned, unless you’re getting an acknowledgment, in which case you may have already signed it.
The notary verifies your identity. You’ll need a current, government-issued photo ID. A state driver’s license, state identification card, or U.S. passport are accepted virtually everywhere. Some states also accept military IDs, permanent resident cards, and foreign passports. Most states do not allow expired identification, though a handful make exceptions for IDs that expired within the past five years. If you lack acceptable ID, some states allow the notary to identify you through one or two “credible witnesses” who know both you and the notary and who swear under oath that you are who you claim to be. This is a last resort, not a shortcut.
You then sign the document (for a jurat) or acknowledge your existing signature (for an acknowledgment), and the notary confirms you’re acting willingly. The notary completes the notarial certificate attached to your document, recording what act was performed, the date, and their commission details, then affixes their official seal or stamp. Finally, the notary logs the transaction in a journal, typically recording the date, type of act, your identification, and a description of the document. Most states require this journal, and in some states it has to be a bound physical book with sequentially numbered pages. The record exists to protect both you and the notary if questions arise later about whether the notarization actually occurred or whether the right person signed.
Types of Notarial Acts
Not every notarization works the same way. The act a notary performs depends on what the document is and what it’s for.
Acknowledgments
An acknowledgment is the most common notarial act. You appear before the notary and confirm that the signature on the document is yours and that you signed willingly. The notary verifies your identity but does not require you to sign in their presence. Real estate deeds and powers of attorney typically call for acknowledgments.
Jurats
A jurat goes further. You must sign the document in front of the notary, and the notary administers an oath or affirmation requiring you to swear that the contents are truthful. Lying in a document notarized with a jurat exposes you to perjury charges. Affidavits and sworn statements almost always require a jurat.
Oaths and Affirmations
Oaths and affirmations are verbal pledges of truthfulness that a notary administers without necessarily attaching them to a written document. An oath invokes a higher power; an affirmation carries the same legal weight without religious language. Depositions and certain government proceedings use this act.
Copy Certifications
Some states authorize notaries to certify that a photocopy of an original document is a true and accurate reproduction. This is commonly used for passports, diplomas, or similar records where the original cannot be surrendered. Not all states permit copy certifications, and certain documents like birth certificates can only be certified by the issuing agency regardless of state law.
What a Notary Cannot Do
This is where expectations most often collide with reality. The limits of a notary’s role are strict, and knowing them before you walk in saves confusion.
A notary cannot explain what a document means, advise you on whether to sign, suggest changes to legal language, or prepare legal documents for you. Doing so constitutes the unauthorized practice of law, which can result in criminal charges, fines, and revocation of the notary’s commission. If you need help understanding a document, consult an attorney before your notary appointment. The notary’s job is limited to verifying identity and witnessing signatures.
This distinction matters especially in immigrant communities, where the Spanish word “notario” implies a legal professional with far more authority than a U.S. notary public possesses. A U.S. notary who advertises legal services to non-English-speaking clients faces additional penalties in many states.
A notary also must remain a disinterested party. They cannot notarize their own signature, and they generally cannot notarize a document in which they have a direct financial interest or are named as a party. Many states extend this prohibition to close family members. The specific rules vary: some states prohibit notarizing for any relative by blood or marriage, while others allow employees to notarize for their employers as long as the only compensation is their regular salary and the standard notary fee.
When a Notary Must Refuse
A notary has a legal obligation to refuse notarization when something isn’t right. Knowing the common grounds can save you a wasted trip.
- You can’t produce a valid, government-issued photo ID and no credible witness is available.
- The signer isn’t physically present. No exceptions for “my spouse signed it at home.”
- The signer appears disoriented, heavily medicated, or unable to communicate clearly. The notary must be satisfied that you understand what you’re signing.
- Someone else in the room appears to be pressuring you, or you seem reluctant or fearful.
- The document shows visible alterations, missing pages, or blank spaces that could be filled in after notarization.
These refusals protect you. A notary who waves through a questionable transaction exposes both the signer and themselves to serious legal consequences, which can escalate from fines and suspension of the notary’s commission up to felony charges for things like notarizing without the signer present or knowingly facilitating fraud.
Documents That Commonly Require a Notary
Certain transactions carry enough legal or financial weight that the law or the receiving party demands independent verification of who signed. The usual categories include:
- Real estate transfers. Deeds, mortgage documents, and deeds of trust almost always require notarization before a county recorder will accept them for filing.
- Powers of attorney. Financial, healthcare, and durable powers of attorney generally require notarization to be enforceable.
- Affidavits and sworn statements. Court filings, immigration support affidavits, and identity affidavits typically need a notary to administer the oath that makes the statement legally binding.
- Estate planning documents. Living trusts generally require notarization. Wills vary by state, though a notarized self-proving affidavit attached to a will can prevent the need for witnesses to testify later in probate.
- Travel and guardianship consents. A child traveling internationally with only one parent often needs a notarized consent letter from the other parent. Temporary guardianship agreements typically require notarization as well.
- Business formation documents. Articles of incorporation, commercial leases, and certain high-value contracts may require notarized signatures depending on the jurisdiction.
If you’re unsure whether your document needs notarization, check with the agency, lender, or court that will receive it. Submitting an unnotarized document when one is required means it gets sent back, and the delay can hold up a closing, a court deadline, or an immigration filing. A defective notarization has the same effect: there’s no way to retroactively cure a bad notarization, so you start over with a clean document.
Remote Online Notarization
You no longer need to be in the same room as the notary in most states. As of 2025, 47 states and the District of Columbia have enacted laws permitting remote online notarization, where the signer and notary connect through a live audio-video session rather than meeting face to face. 1NASS.org. Remote Electronic Notarization
Remote online notarization requires identity verification that goes beyond what traditional notarization demands. The signer typically undergoes two or more forms of identity proofing: credential analysis, which checks an uploaded photo of a government ID against databases, and knowledge-based authentication, which draws questions from public records that only the real person should know. The entire session is recorded on audio and video, and the recording must be retained for a set period, often ten years. The notary applies a digital seal and electronic signature rather than a physical stamp.
Remote online notarization is distinct from electronic notarization, which uses electronic signatures and digital seals but still requires everyone to be physically present in the same room. If a service advertises “e-notarization,” confirm whether it’s truly remote or just a paperless version of an in-person appointment.
Finding a Notary and What It Costs
Banks and credit unions often provide notary services free of charge to account holders. UPS stores, FedEx Office locations, and other shipping and print shops typically have a notary on staff during business hours. Public libraries, AAA offices, and some employers also offer the service. For after-hours or on-location needs, mobile notaries travel to you, whether at home, a hospital, or a law office.
State law caps the maximum fee a notary can charge per act. For in-person notarizations, those caps range from as low as $2 in a handful of states to $25 in others, with most falling between $5 and $15 per signature or per act. Remote online notarization fees run higher, with most states capping them at $25 per act, sometimes with an additional technology surcharge. Mobile notaries typically charge a separate travel fee on top of the per-act charge, often anywhere from $25 to $75 or more depending on distance, time of day, and local market rates.
When you arrive, bring the document (unsigned, unless an acknowledgment), a current government-issued photo ID, and any additional signers who need to be present. If the document also requires witnesses, arrange for them to attend as well. The notary and the witnesses serve different functions and usually cannot be the same person.
One boundary worth flagging if you plan to use the document abroad: a U.S. notarization doesn’t automatically carry weight in another country. Most receiving countries require an apostille from the secretary of state where the notary is commissioned, or from the U.S. Department of State for documents signed by federal officials. 2U.S. Department of State. Preparing a Document for an Apostille Certificate Confirm the requirements with the receiving country before your appointment, because for federal documents, adding a notarization can actually invalidate the document for apostille purposes.
