Notaries verify your identity and witness your signature on important documents

A notary's job is to watch you sign a document and confirm that you are who you say you are. They do not read the document, judge whether it is fair, or decide if you should sign it. They straightforward verify three things: your identity (usually by checking a government ID), that you are signing of your own free will, and that you understand you are signing. Then they stamp and sign the document themselves, adding their official seal.

The notary's signature and seal tell whoever receives the document later that a trained, licensed person witnessed the signing. This matters because it makes the document harder to forge and creates a record that you actually signed it on a specific date. Many legal and financial transactions require notarization because the other party needs proof that the signature is real.

Key Takeaways

  • Notaries watch you sign documents and verify your identity using a government-issued ID before they stamp and sign the page.
  • Real estate transactions, power of attorney documents, and loan paperwork commonly require notarization to prove the signature is genuine.
  • You must appear in person in front of the notary; they cannot notarize a document you sign elsewhere or mail to them.
  • Notaries are trained and licensed by the state where they work, and they keep a record of every document they notarize.
  • The cost is usually between five and twenty dollars per signature, depending on your state and the notary's location.

Common documents that need notarization

Real estate deeds, mortgages, and property transfers almost always require notarization because the stakes are high and the documents are recorded in public records. Banks and title companies will not close a sale without a notarized deed.

Power of attorney documents—where you give someone legal authority to act on your behalf—need notarization in most states. Loan documents, including personal loans and car loans, often require it. Affidavits (sworn statements you make under oath) must be notarized. Adoption papers, guardianship documents, and some healthcare directives also commonly require a notary's signature.

Less obvious uses include notarizing copies of your passport or driver's license for visa applications, certifying that a photocopy matches the original document, and witnessing the signing of wills in some states. If you are unsure whether a document needs notarization, check the document itself—it usually says "notary public" somewhere on the page, or ask the person or organization requesting it.

Why notarization matters for legal protection

Notarization creates a paper trail. The notary keeps a journal that records the date, the document type, the signer's name, and the ID they used. If someone later claims you never signed something, or that you signed under duress, that journal entry is evidence. It is not absolute proof, but it is strong evidence that you were present and willing.

For real estate and financial institutions, notarization reduces fraud risk. A forged deed or power of attorney can cost thousands of dollars to undo. The notary's seal makes forgery harder because it requires access to official stamps and journals that are tracked by the state. Banks and title companies trust notarized documents more than unsigned ones because they know a third party verified the signature.

Notarization also protects you. If you sign a document in front of a notary, you have a witness to the fact that you understood what you were signing and that you did it willingly. This is especially important for power of attorney documents, where someone might later claim you were confused or pressured.

How to find a notary and what to bring

Notaries work in banks, law offices, real estate agencies, UPS stores, and some pharmacies. Many work independently and advertise online or through local directories. Search "notary public near me" to find options in your area. Some notaries travel to you for an extra fee, which can be useful if you are elderly or have mobility issues.

Bring the unsigned document and a government-issued photo ID—a driver's license, passport, or state ID card. The notary will not accept expired IDs in most states. If you have already signed the document, the notary cannot notarize it; they must watch you sign. Bring a pen (though many notaries provide one). If the document has multiple pages, bring all of them, even if only one page needs the notary's signature.

Call ahead to confirm the notary is available and ask about their fee. Some notaries charge per signature rather than per document, so if a document has three places to sign, you may pay three times. Ask whether they need an appointment or accept walk-ins. Bring cash or ask what payment methods they take.

What notaries cannot do

A notary cannot give legal information or tell you whether a document is fair or whether you should sign it. They cannot notarize a document they wrote or have a financial interest in. They cannot notarize a blank document or one with blank spaces you plan to fill in later. They cannot notarize a document you signed before you arrived—they must watch you sign in front of them.

Notaries cannot notarize documents for themselves or their when ready family members in most states. They cannot notarize a document if they cannot verify your identity with an acceptable ID. They cannot notarize a document written in a language they do not understand, unless an interpreter is present and they notarize the interpreter's certification as well.

If a notary asks you to sign something you do not understand, or pressures you to sign, you can refuse and find another notary. A notary's job is to verify identity and witness, not to persuade.

Notarization versus other types of document verification

Notarization is different from certification, which is when a notary compares a photocopy to an original document and certifies that the copy is accurate. You bring the original and the copy, and the notary stamps the copy to confirm it matches. This is common for passport copies, birth certificates, and diplomas.

Apostille is a special type of notarization used for documents that will be used in another country. An apostille is a certificate added to a notarized document that confirms the notary's signature and seal are valid under international law. You cannot get an apostille from any notary—you usually need to go through your state's Secretary of State office or a notary who specializes in apostilles.

Acknowledgment and jurat are two different types of notarization. An acknowledgment means the notary watched you sign and confirmed your identity. A jurat means you swore under oath that the contents of the document are true. Most documents require an acknowledgment; affidavits and some legal statements require a jurat. The document itself will specify which one is needed.

Notary requirements by state

Every state licenses and regulates notaries, but the rules vary. Some states require notaries to pass an exam and take a training course; others have minimal requirements. Notary commissions last between two and ten years depending on the state, and notaries must renew them periodically.

Fees vary by state. Some states set a maximum fee (often around ten to fifteen dollars per signature), while others allow notaries to charge whatever they want. Urban areas and notaries in busy locations often charge more than rural notaries.

If you are moving to another state or need a notary in a different state, check that state's Secretary of State website for rules about who can notarize and what documents require it. Some documents notarized in one state are accepted in another, but not always. When in doubt, ask the organization requesting the notarization whether they will accept a notarization from out of state.

Frequently Asked Questions

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

No. The notary must watch you sign the document in front of them. If you have already signed it, they cannot notarize it. You will need to get a blank copy and sign it in the notary's presence.

What if I do not have a government ID?

Most notaries will not notarize without a government-issued photo ID. If you do not have a driver's license or passport, you may be able to use a state ID card or passport card. If you have none of these, ask the notary whether they accept alternative forms of ID, though most will not.

Can I notarize a document online or by video?

Some states allow remote notarization by video, but it is not available everywhere. The notary must use special software to verify your identity and watch you sign electronically. Ask your notary whether they offer this service, or check your state's Secretary of State website to see if remote notarization is legal in your state.

How long does a notarized document stay valid?

A notarized document does not expire. Once notarized, it remains notarized. However, the organization using the document may have its own rules—for example, a bank might require a power of attorney to be notarized within the last six months. Check with the organization requesting the notarization.

What is the difference between a notary and a lawyer?

A notary verifies your identity and witnesses your signature. A lawyer gives legal information and can represent you in court. Some people are both, but notaries are not required to have a law degree, and most do not. Do not ask a notary for legal information.
