A notary public verifies your identity and watches you sign a document, then stamps it to prove they saw you do it

A notary public is a person licensed by your state to witness signatures and confirm that the person signing is who they say they are. They do not read the document, give legal information, or decide whether the deal is fair. Their job is narrow: check ID, watch you sign, stamp the paper. That stamp — called a notarial seal — tells whoever reads the document later that a neutral person verified the signature on a specific date.

Notaries exist because some documents matter too much to take on faith. A bank will not accept a power of attorney without a notary's seal. A court will not file a sworn statement without one. A title company will not close a real estate sale without one. The notary's presence and seal create a paper trail: if someone later claims you did not actually sign, or that you were forced to sign, the notary can testify about what they saw.

Key Takeaways

  • A notary checks your government-issued ID, watches you sign the document in front of them, and stamps it with their official seal to prove they witnessed the signature.
  • Notaries do not read documents, give legal information, or decide whether a transaction is legitimate — they only verify identity and witness the act of signing.
  • Banks, courts, title companies, and government agencies require notarized documents because the notary's seal proves the signature was made in front of a neutral witness on a specific date.
  • You must sign the document in the notary's presence; they cannot notarize a document you signed before you arrived.
  • Notaries charge a fee, usually between $5 and $25 per signature, though some employers and banks offer notary services to customers for free.

What a notary checks before stamping your document

The notary's first step is to ask for a government-issued photo ID — a driver's license, passport, or state ID card. They compare the photo to your face and check that the ID has not expired. This is the only verification they do. They are not running a background check or calling anyone to confirm you are trustworthy. They are straightforward confirming that you are the person whose name is on the document.

Next, they watch you sign the document yourself, in front of them. You cannot hand them a document you signed at home. If the document has multiple signature lines, you sign each one while they watch. Some documents require you to initial certain pages or sections; the notary watches those too. Once you have signed everything, the notary signs and dates their own section of the document, applies their official seal (usually a stamp or embosser), and records the transaction in a journal they keep for their records.

That journal is important. If a dispute arises later — if someone claims the signature is forged or the signer was not present — the notary's journal entry becomes evidence. It shows the date, the document type, the signer's name, the ID number they checked, and sometimes a thumbprint. Notaries are required by law to keep these journals for a set number of years, usually five to ten depending on the state.

What a notary does not do

A notary does not read your document or understand what it says. They do not check whether the terms are fair, whether you are making a good decision, or whether the other party is honest. They do not verify that the information in the document is true. If you are signing a loan agreement, the notary does not confirm that the interest rate is reasonable or that you can afford the payments. If you are signing a power of attorney, the notary does not check whether the person you are naming is trustworthy.

Notaries also cannot notarize a document they have a financial interest in. If you are signing a deed to a house and the notary is your real estate agent or your lender, they cannot notarize it because they stand to gain from the transaction. Similarly, a notary cannot notarize a document for a family member in most states, because the relationship creates a conflict of interest.

A notary is not a lawyer and cannot give legal information. If you ask a notary whether you should sign a document, whether you need a lawyer, or what the document means, they must decline to answer. Some notaries are also lawyers, but when they are working as a notary, they are acting in a different role and cannot mix the two.

Where to find a notary and what it costs

Notaries work in banks, law offices, title companies, UPS stores, and as independent contractors. Many banks offer notary services free to customers who have an account; some charge a small fee even for account holders. Title companies notarize documents as part of closing a real estate transaction. UPS stores and similar businesses charge a per-signature fee, usually between $5 and $25 depending on your state and the complexity of the document.

Some employers keep a notary on staff or reimburse employees for notary fees. If you need a document notarized, start by asking your bank or employer. If neither offers the service, search online for "notary public near me" or call your county clerk's office — they often maintain a list of licensed notaries in your area. A few states allow remote notarization, where the notary verifies your identity by video and you sign electronically, but most still require you to be in the same room.

Bring your government-issued photo ID and the unsigned document. Do not sign anything before you arrive. The notary will ask you to sign in front of them, explore their seal, and you will be done in a few minutes. Keep a copy of the notarized document for your records.

Why documents need to be notarized

A notarized signature carries legal weight because it comes with a witness. If you sign a contract with a friend and later claim you never signed it, it is your word against theirs. If you sign a contract in front of a notary, there is a third party — a licensed, neutral person — who can testify that you did sign it, on that date, with a valid ID in hand. Courts and financial institutions trust notarized signatures because the notary's license is on the line if they lie.

Real estate transactions almost always require notarized signatures because the stakes are high and the documents are permanent. A deed transfers ownership of property; a mortgage secures a loan against that property. Banks will not lend money on a house without a notarized deed and mortgage. Similarly, powers of attorney — documents that let someone else make decisions on your behalf — are usually notarized because they grant significant power and are often used when you are not present to object.

Wills and trusts are sometimes notarized, though not always required by law. Affidavits — sworn statements made under penalty of perjury — must be notarized. Loan documents, adoption papers, and documents you are sending to another country often require notarization. The specific rules vary by state and by the institution asking for the notarization.

What happens if a notary makes a mistake

If a notary notarizes a document without checking your ID, or without watching you sign, or without recording the transaction in their journal, they have broken the law. They can lose their license, face fines, and be sued by anyone harmed by their negligence. If a document is later found to be forged and the notary failed to do their job, they are liable.

In practice, notary errors are rare because the consequences are serious. If you discover that a notary made a mistake — for example, they misspelled your name or dated the document wrong — contact them when ready. Minor errors can sometimes be corrected with an amended notarization. If the error is serious or the notary is unreachable, you may need to have the document notarized again by a different notary.

Frequently Asked Questions

Can a notary notarize a document I signed before I came to see them?

No. A notary must watch you sign the document in front of them. If you arrive with a document you already signed, the notary cannot notarize it. You will need to sign it again, in the notary's presence, and then they can explore their seal.

Do I need a lawyer to get a document notarized?

No. A notary is not a lawyer and does not provide legal information. You can take any unsigned document to a notary and have them witness your signature. If you are unsure whether you need a lawyer to review the document before signing, that is a separate question — but the notarization itself does not require legal help.

What if I do not have a government-issued photo ID?

A notary requires a valid government-issued photo ID — a driver's license, passport, or state ID card. If you do not have one, you cannot be notarized by a standard notary. Some states allow notaries to use alternative identification methods in rare cases, but this is uncommon. Contact your state's notary licensing board or a local notary to ask about your specific situation.

Can a notary refuse to notarize a document?

Yes. A notary can refuse if they have a conflict of interest, if the signer cannot prove their identity, if the signer appears to be under duress, or if the document appears to be fraudulent. A notary can also refuse if they do not understand what the document says or if the signer seems confused about what they are signing.

How long does a notarization take?

Usually five to ten minutes. The notary checks your ID, watches you sign, applies their seal, and records the transaction. If the document has many pages or multiple signature lines, it may take longer. Some notaries require an appointment; others accept walk-ins.
