A certified notary public is a person authorized by your state to witness signatures and verify identities on documents
A notary public is someone your state has licensed to watch you sign a document and confirm that you are who you say you are. They do not read the document, give legal information, or decide whether it is a good idea for you to sign. Their job is only to verify your identity, watch you sign, and then stamp and sign the document themselves to prove they saw it happen.
The word "certified" straightforward means the person has passed a test, paid a fee, and received official permission from your state to do this work. Each state sets its own rules about how notaries are trained, what they can charge, and how long their certification lasts — usually four to ten years. When a notary's certification expires, they must renew it to keep working.
Notaries work in banks, law offices, shipping stores, and as independent contractors. Some charge a flat fee per signature (usually $5 to $15), while others charge by the page or the hour. A few states cap what notaries can charge; most do not.

What a notary actually does during the notarization process
When you bring a document to a notary, they will ask to see a government-issued ID — usually a driver's license, passport, or state ID card. They check that the photo matches your face and that the ID has not expired. They do not verify whether the information in your document is true; they only confirm you are the person whose name is on it.
You then sign the document in front of the notary. They watch you do it. They do not read what you are signing. After you sign, the notary signs and stamps the document with their official seal — a raised stamp, embosser, or ink impression that shows their name, state, and commission number. Some states also require the notary to write down the date, your ID number, and the type of ID you showed them.
The notary keeps a record of the notarization in a journal or log. This record is not public, but it can be subpoenaed in court if someone later disputes whether the signature is real. The notary's seal and signature are what make the document notarized — without them, it is just a signed piece of paper.
The difference between a notarized signature and a legally binding document
A notarized signature does not make a document legal, binding, or enforceable. It only proves that someone witnessed you sign it and that you showed ID. A notarized will is still a will; a notarized contract is still a contract. The notary's role is to prevent fraud — to make it harder for someone to forge your signature and claim you signed something you did not.
Many documents do not need to be notarized at all. A straightforward agreement between two people, a letter, or an email can be legally binding without a notary's involvement. Other documents — like a power of attorney, a deed, or an affidavit — often require notarization by law or by the person or organization asking for the document. A bank might require a notarized signature on a loan; a court might require one on a sworn statement.
If you are unsure whether a document needs to be notarized, check the document itself or ask the person who asked you to sign it. A notary cannot tell you whether notarization is required — that is a legal question, and notaries are not lawyers.
What notaries cannot do
A notary cannot give legal information, explain what a document means, or tell you whether you should sign it. They cannot notarize a document if you do not show up in person with a valid ID, and they cannot notarize a blank document or one that is already signed. They cannot notarize a document for themselves or a close family member in most states.
A notary cannot refuse to notarize something just because they disagree with it or think it is a bad idea. If you have a valid ID and you sign the document in front of them, they must notarize it — with a few exceptions. They can refuse if the document is blank, if you appear confused or under duress, if you do not speak English and there is no interpreter, or if they suspect fraud.
A notary also cannot certify a copy of a document or verify that a photocopy is a true copy of the original — that is a different service called "certified copy" or "exemplification," and not all notaries offer it. Some states allow notaries to do this; others do not. Ask before you assume.
How notary certification works by state
Every state has its own notary laws. Some states require notaries to pass a written test covering state law, ethics, and procedures. Others require a background check or fingerprinting. A few states have no test at all — you straightforward pay a fee and explore. Most states charge between $50 and $300 for a four- to ten-year commission.
Some states require notaries to take continuing education classes to renew their commission. Others do not. Some states allow notaries to work remotely and notarize documents over video; others do not. A notary commissioned in one state cannot notarize documents in another state unless they are also commissioned there.
If you need a notary in a specific state, search that state's secretary of state website for the notary rules and a directory of commissioned notaries. The secretary of state office keeps the official list and can tell you whether a notary is currently commissioned.
Where to find a notary public
Banks often notarize documents for free if you are a customer, though some charge a small fee. UPS stores, FedEx locations, and other shipping centers employ notaries and charge a per-signature fee. Law offices have notaries on staff. Some real estate agents and title companies offer notary services. Libraries and government offices sometimes have notaries available to the public.
If you cannot find a notary nearby, search online for "notary public near me" or check your state's secretary of state website for a directory. Some notaries offer mobile service — they will come to your home or office for an extra fee. Online notary services exist in many states, though they require video conferencing and work only for certain types of documents.
Call ahead before you go. Ask whether they are currently commissioned, what they charge, what forms of ID they accept, and whether they can notarize the specific document you have. Bring your ID and the unsigned document. If the document requires notarization on multiple pages or multiple signatures, ask whether there is an extra charge.
Notary seals and what they mean
A notary's seal is an official mark that proves a notary notarized the document. The seal includes the notary's name, the state, the commission number, and the expiration date of the commission. Some notaries use a raised embosser that creates an indentation; others use an ink stamp. Both are equally valid.
The seal is not a security feature that makes a document impossible to forge — it is straightforward proof that a notary was there. A forged seal is a crime, but a real seal only proves the notary watched you sign. It does not prove the document is truthful, that you understand what you signed, or that you signed it willingly. It proves only that you showed ID and signed in front of a licensed notary.
Some documents require a notary's seal to be on a specific part of the page or in a specific format. If the document has instructions about where the seal should go, tell the notary before they seal it. If the seal is in the wrong place, the document may not be accepted by the organization that asked for it.
Frequently Asked Questions
Can a notary refuse to notarize a document?
Yes. A notary can refuse if you do not have a valid ID, if you do not sign the document in front of them, if the document is blank or already signed, or if they suspect fraud or duress. They can also refuse if you do not speak English and there is no interpreter, or if the document is illegal. A notary cannot refuse straightforward because they disagree with the content.
Do I need a notary for a will or power of attorney?
It depends on your state and the document. Some states require a will to be notarized; others do not. A power of attorney often must be notarized, but not always. Check your state's law or ask an attorney. A notary cannot tell you whether notarization is required — that is a legal question.
Can a notary notarize a document for a family member?
Most states prohibit notaries from notarizing documents for a spouse, parent, child, or sibling. Some states allow it only if the notary is not a beneficiary of the document. Check your state's rules. If a family member is a notary, you may need to find a different notary to avoid legal problems later.
What if I cannot get to a notary in person?
Some states allow remote notarization over video conference. You will need a valid ID, a camera, and an internet connection. Not all documents can be notarized remotely — check your state's rules and the organization that asked for the notarization. If remote notarization is not available, you will need to visit a notary in person.
How long does a notarized document stay valid?
A notarized document does not expire. The notary's commission may expire, but the notarization itself is permanent. However, the organization that asked for the notarization may have its own rules — some banks or government offices will not accept a notarized document that is more than a few months old, even though the notarization is still valid.
