A public notary is a person authorized by the state to witness signatures and verify identities on important documents

A public notary (also called a notary public) is someone officially appointed by your state 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 purely to witness the signature and verify the signer's identity, then stamp and sign the document themselves to prove they did this.

The notary's stamp and signature tell other people — banks, courts, government offices, or title companies — that someone official saw the real person sign the real document on a real date. This matters because many important transactions require proof that a signature is genuine, not forged or coerced. Without a notary, a signature is just ink on paper.

Key Takeaways

  • A public notary witnesses your signature and checks your photo ID to confirm you are the person signing the document.
  • The notary does not read, explain, or judge the document — they only verify identity and witness the act of signing.
  • Banks, courts, and government offices often require notarized documents because the notary's seal proves the signature is genuine.
  • You can find notaries at banks, UPS stores, law offices, and some libraries; fees typically range from five to fifteen dollars per signature.

What a notary actually does during the signing

When you bring a document to a notary, they will ask to see a photo ID — a driver's license, passport, or state ID card. They check that the name on the ID matches the name on the document and that the photo looks like you. This step prevents someone from forging your signature by pretending to be you.

Next, the notary watches you sign the document in front of them. You cannot sign it beforehand and bring it already signed — the notary must see the actual signing happen. After you sign, the notary signs and stamps the document with an official seal that includes their name, the state they are commissioned in, and the date. Some states also require the notary to write down information about your ID in a journal they keep.

The entire process usually takes five to ten minutes. The notary does not care what the document says or whether you understand it. If you ask them to explain the legal meaning of something in the document, they cannot do that — it would cross into legal information, which only a lawyer can give.

Why documents need to be notarized

Notarization is required for documents where a false or forged signature could cause serious harm or fraud. Real estate deeds, powers of attorney, affidavits, and loan documents almost always need notarization. A bank will not lend you money on a mortgage without a notarized deed. A court will not accept a power of attorney unless a notary has verified the signature.

Some documents are notarized even though the law does not strictly require it, straightforward because the other party — a bank, employer, or government office — will not accept it without the notary's seal. For example, a notarized letter from your employer confirming your income may not be legally required, but a mortgage lender might ask for one anyway to reduce their risk.

Where to find a public notary

Most banks offer notary services to customers for free or a small fee. Call ahead to confirm they have a notary on staff and ask about their hours, since notaries are not always available at every branch location. UPS stores, FedEx offices, and some CVS and Walgreens locations also have notaries; fees are usually five to fifteen dollars per signature.

Law offices, title companies, and real estate offices employ notaries and will notarize documents for you, though they may charge more than retail locations. Some public libraries offer notary services free or for a small fee. If you need a notary outside normal business hours, search online for "24-hour notary near me" — mobile notaries will come to your home or office for a higher fee, usually twenty to fifty dollars.

What you need to bring to a notary

Bring the unsigned document and a valid photo ID. The ID must be current (not expired) and issued by a government agency — a driver's license, passport, state ID card, or military ID all work. Some notaries will accept an expired ID if it is recent, but do not count on it.

If the document has multiple pages, bring all of them. Some notaries will only notarize the signature page, while others notarize the entire document. Ask beforehand if you are unsure. Do not sign the document before you arrive — you must sign it in front of the notary. If you have already signed it, the notary cannot notarize it.

Common mistakes that delay notarization

The most common mistake is arriving with an already-signed document. The notary must watch you sign, so if you signed it at home, you will have to cross out your signature, initial the change, and sign again in front of the notary. This looks messy and some notaries will refuse to notarize it.

Another mistake is bringing an expired ID. Some notaries will work with you if the ID is only slightly expired, but many will not. Bring a current photo ID to avoid this problem. Also, make sure the name on your ID exactly matches the name on the document. If you recently changed your name and the document uses your old name, or if there is a spelling difference, tell the notary before they notarize — they may need to note the discrepancy on the document.

Notarization versus other types of document verification

Notarization is different from having a document witnessed by a regular person. A witness just signs to say they saw you sign, but they have no official authority and no one trusts their signature the way they trust a notary's. Notarization is also different from certification, where someone (usually a government office) makes a copy of an original document and stamps it to say the copy is accurate.

Some documents require both notarization and certification. For example, a certified copy of your birth certificate is a copy that the vital records office has stamped to confirm it matches the original. If you then need that certified copy notarized, a notary would watch you sign a statement saying the certified copy is yours, and stamp that statement.

Frequently Asked Questions

Can a notary refuse to notarize a document?

Yes. A notary can refuse if they believe the signer is being coerced, if the signer appears unable to understand what they are signing, if the ID does not match the person, or if the document appears to be for an illegal purpose. A notary can also refuse if they have a personal interest in the document — for example, they cannot notarize a document they are also signing as a party to the agreement.

Do I need a notary if the document is digital or electronic?

Some electronic documents can be notarized digitally through a process called remote online notarization, where you sign on video while the notary watches. However, not all states allow this yet, and not all documents can be notarized remotely. Ask the person requesting the notarized document whether they will accept a digital notarization or need a paper one.

What if I cannot get to a notary in person?

Some states allow remote online notarization, where you sign the document on a video call with a notary. Search for "remote notary" or "online notary" in your state. If your state does not offer this, you can hire a mobile notary to come to your home or office, though this costs more than visiting a notary in person.

How long does a notarized document stay valid?

A notarized document does not expire just because time has passed. However, the organization asking for the notarization may have its own rules — for example, a bank might require a notarized document to be no more than six months old. Check with the person requesting the document to see if they have a time limit.

Can a notary notarize a document in a language I do not speak?

A notary can notarize a document in any language, since they are only verifying the signature and identity, not reading the content. However, if the notary cannot read the language, they cannot confirm that you understand what you are signing. Some notaries will require an interpreter to be present, or they may refuse the job. Ask the notary before you arrive.
