Notarizing means an official witness confirms your identity and watches you sign

When you notarize a document, a notary public — a person licensed by your state — watches you sign it in person, checks your ID, and then adds their official stamp and signature to the page. That stamp and signature are proof that you actually signed the document yourself, on that date, in front of someone who verified who you are. The notary does not read the document, does not judge whether it is fair, and does not check whether you understand what you are signing. Their job is only to confirm that you are the person whose name is on the document and that you signed it willingly.

The reason documents get notarized is straightforward: it makes forgery much harder. If someone forges your signature on a contract or a deed, they would also have to forge the notary's stamp and signature — which is a separate crime and much more difficult. Banks, courts, and government agencies ask for notarized documents because the notary's seal proves the signature is real.

Key Takeaways

  • A notary watches you sign a document in person, checks your ID, and stamps the page to confirm the signature is genuine.
  • The notary does not read or judge the document — they only verify your identity and that you signed willingly.
  • Common documents that need notarizing include powers of attorney, affidavits, property deeds, and loan documents.
  • You must appear in person with a valid ID; the notary cannot notarize a document you sign at home or mail in.
  • Notarization costs between $5 and $25 per signature, depending on your state and the notary's location.

What the notary actually does during the process

When you arrive at a notary with your unsigned document and ID, the notary will ask you to confirm your name and address. They will examine your ID — usually a driver's license, passport, or state ID card — to make sure the photo matches your face and the name matches the document. They will ask you to sign the document in front of them while they watch. Some notaries will ask you to initial each page or to state that you understand what you are signing, though this varies by state.

Once you have signed, the notary writes the date, your name, and the type of ID you showed them into a notary journal — a record book they keep for their own protection. Then they stamp the document with their official seal (usually a raised stamp or an inked stamp) and sign it themselves. The seal includes the notary's name, the state they are licensed in, and an expiration date. That seal is what makes the document notarized.

The whole process usually takes five to ten minutes. You cannot mail a document to a notary to sign, and the notary cannot come to your house in most states — you have to be there in person. The notary's job ends when they stamp the page; they do not file it anywhere or send it to anyone.

Which documents commonly need notarizing

Documents that transfer money, property, or legal rights often require notarization because the stakes are high and forgery would be costly. A power of attorney — a document that lets someone else make decisions on your behalf — almost always needs notarizing. So do affidavits (sworn statements you make under penalty of perjury), property deeds, mortgage documents, and loan applications. Wills sometimes need notarizing, though not in every state.

Some documents need notarizing by law; others need it because a bank or court is asking for it. If you are unsure whether your document needs notarizing, check the document itself — it will usually say "notary public" somewhere, or ask the person who gave you the document. A notary can also tell you whether a document needs notarizing when you arrive.

Where to find a notary public

Notaries work in many places. Banks often have notaries on staff, and they will notarize documents for customers for free or a small fee. Law offices, title companies, and real estate offices have notaries. Many UPS stores, FedEx locations, and shipping centers employ notaries. Some libraries and county clerk offices offer notary services. You can search online for "notary public near me" or call ahead to confirm hours and fees.

If you need a notary urgently, banks are usually the fastest option because they have long hours and multiple locations. If you need the document notarized outside normal business hours, some notaries work evenings or weekends — search for "mobile notary" or "24-hour notary" in your area, though these services cost more.

What you need to bring to a notary

Bring your unsigned document and a valid government-issued ID. The ID must have your photo, your current name, and an expiration date that has not passed. A driver's license, passport, state ID card, or military ID all work. Expired IDs are usually not accepted, even if the photo is clearly you. Some notaries will accept a second form of ID if your first one is expired, but this varies — call ahead if you are unsure.

Do not sign the document before you arrive at the notary. The notary must watch you sign it. If you have already signed it, the notary cannot notarize it, and you will have to get a new copy and start over. Bring the original document, not a photocopy, unless the document itself is a photocopy that you are swearing is true.

How much notarization costs

Notary fees vary by state and by location. In most states, a notary can charge between $5 and $25 per signature. Banks often notarize for free if you are a customer. Law offices and title companies may charge $10 to $15. Mobile notaries who come to you usually charge $25 to $50 or more, depending on distance. Some notaries charge a flat fee per document rather than per signature, so if a document has three places to sign, you might pay once or three times depending on the notary's policy.

Call ahead to ask the fee before you go. Some notaries accept cash only; others take cards. If you need multiple documents notarized, ask whether there is a discount for multiple signatures.

Common mistakes to avoid

The biggest mistake is signing the document before you see the notary. Once you sign, the notary cannot notarize it — you will need a fresh copy. Another common mistake is bringing an expired ID. Even if you have other forms of ID, many notaries will refuse to notarize without a current government-issued photo ID.

Do not assume the notary will read your document or tell you whether it is correct. If you have questions about what the document says or whether you should sign it, ask a lawyer before you go to the notary. The notary is there only to verify your identity and watch you sign — not to give legal information.

Finally, do not lose the notarized document. Once it is stamped, you cannot get another copy with the same notary's seal. If you need a copy later, you will have to go back to the notary and ask them to make a certified copy from their journal, which may cost extra.

Frequently Asked Questions

Can a notary notarize a document I signed at home?

No. The notary must watch you sign the document in person. If you have already signed it, you will need a new unsigned copy. The notary's job is to confirm that you signed it yourself, in front of them, on that date.

What if I do not have a current ID?

Most notaries will not notarize without a current government-issued photo ID. If your ID is expired, you can renew it at your state's DMV or passport office. Some notaries may accept a second form of ID in addition to an expired one, but this varies — call ahead to ask.

Can a notary tell me if my document is legal or correct?

No. A notary only confirms your identity and watches you sign. They do not read the document, check whether it is fair, or give legal information. If you have questions about what the document says, talk to a lawyer before you sign.

Do I need to notarize every document I sign?

No. Most everyday documents — contracts, letters, emails — do not need notarizing. Only documents that involve money, property, legal rights, or sworn statements usually require it. The document itself or the person asking for it will tell you if notarization is needed.

What happens if someone forges a notary's seal?

Forging a notary's seal is a separate crime from forging a signature, and it is taken seriously. That is why notarization makes fraud harder — a forger would have to fake both your signature and the notary's official seal, which requires more skill and carries more legal risk.
