A notary verifies your identity and watches you sign documents so that later, nobody can claim you didn't sign them or didn't know what you were signing

A notary is a person licensed by your state to witness signatures and confirm that the person signing is who they say they are. That's the whole job. They don't read the document, don't check if it's legal, don't give you information about whether you should sign it. They watch you sign, check your ID, and stamp the paper to say "I saw this happen on this date."

The point is proof. If you sign a will, a power of attorney, a deed to property, or a loan document without a notary, someone could later say you never signed it, or that you were forced to sign it, or that you didn't understand what you were signing. A notary's stamp and signature say: I checked this person's driver's license, I watched them sign with their own hand, and they told me they understood what they were signing. That makes the document much harder to challenge in court.

Key Takeaways

  • A notary watches you sign a document, checks your ID, and stamps the paper to prove the signature is genuine and witnessed.
  • Notarized documents are harder to dispute in court because a third party has confirmed the signer's identity and willingness.
  • Many legal documents—wills, powers of attorney, deeds, loan papers—require notarization by law in most states.
  • You can find notaries at banks, UPS stores, law offices, and some government offices; fees are usually $5 to $15 per signature.
  • A notary cannot give legal information, explain what a document means, or tell you whether you should sign it.

When notarization is required by law

Your state law decides which documents must be notarized. The most common ones are wills, trusts, powers of attorney, real estate deeds, and mortgage documents. If you're signing a will and your state requires notarization, a will without a notary's stamp may not be accepted by probate court, even if witnesses signed it.

Some documents don't require notarization by law but are notarized anyway because it makes them stronger evidence. A contract between two businesses, for example, isn't usually required to be notarized, but one party might ask for it to reduce the chance of a dispute later. Always check your state's rules or ask the person requesting the document whether notarization is required or just recommended.

What a notary actually checks

A notary's job has three parts: check your ID, watch you sign, and record what happened. They will ask to see 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 hasn't expired. If you don't have one, most notaries cannot proceed, though a few states allow notaries to use other methods like having a credible witness vouch for you.

Then they watch you sign the document yourself, in front of them. You cannot sign it beforehand and bring it to them. They need to see your hand move across the paper. After you sign, the notary signs and stamps the document, writes the date, and often records your name, ID number, and the type of ID in a journal. That journal is a record they keep in case someone later questions whether the notarization actually happened.

What a notary will not do

A notary is not a lawyer and cannot give legal information. They cannot tell you whether a document is fair, whether you should sign it, or what it means. If you're confused about what you're signing, a notary will not explain it to you. They can only confirm that you are who you say you are and that you're signing of your own will.

A notary also cannot notarize a blank document, a document with blanks you plan to fill in later, or a document where the signature line is already signed. They must see the actual document you intend to sign, with all the words in place, and watch you sign it in that moment.

Where to find a notary and what it costs

Banks often have notaries on staff, and many will notarize documents for free if you're a customer. UPS stores, FedEx Office locations, and some pharmacy chains offer notary services for a fee, usually $5 to $15 per signature. Law offices, title companies, and real estate offices have notaries. Some county clerk offices and public libraries offer notary services, sometimes free and sometimes for a small fee.

Call ahead to confirm the notary is available and ask about the fee. Bring your government-issued photo ID and the document you need notarized. If you're signing multiple documents or multiple copies of the same document, each signature may be charged separately, so ask about the total cost before you sit down.

Remote notarization: signing from a distance

Some states now allow remote notarization, where you sign a document over a video call with a notary. The notary watches you on camera, confirms your ID (usually by scanning it into the video), and you sign the document in front of your camera. The notary then sends you the stamped document electronically or by mail.

Remote notarization is faster and more convenient, but not all states allow it, and not all documents can be notarized remotely. Real estate deeds, for example, often cannot be notarized remotely in most states because the law requires the notary to be physically present. Check your state's rules or ask the person requesting the notarization whether remote is acceptable for that particular document.

What happens if you sign without a notary when one is required

If your state law requires notarization and you sign without it, the document may not be valid. A will without required notarization might be rejected by probate court. A deed without notarization might not be recorded with the county, which means the property transfer isn't official. A power of attorney without notarization might be refused by a bank or hospital.

The consequences depend on what the document is and what your state requires. Some documents can be fixed later by having them notarized retroactively, though that's more complicated and may require the other party to agree. The safest approach is to ask before you sign: "Does this document need to be notarized?" If the answer is yes or maybe, get it notarized the first time.

Frequently Asked Questions

Can a notary notarize a document for a family member?

Most states allow it, but some prohibit a notary from notarizing for a spouse or close relative. A few states require the notary to disclose the relationship in the journal. Call the notary before you go, or ask your state's notary office whether there are restrictions. When in doubt, use a different notary to avoid any question later.

What if I can't get to a notary in person?

If your state allows remote notarization, you can sign over video. If not, some notaries will travel to you for a higher fee, usually $25 to $50 or more depending on distance. Ask the notary whether they offer mobile services. Otherwise, you'll need to go to them or find someone else who can travel.

Do I need a notary if the document is already witnessed by two people?

Not necessarily. Some documents—like wills in some states—can be valid with witnesses instead of a notary. But if the law requires notarization, witnesses don't replace it. Always check your state's rules for the specific document type, or ask the person requesting it whether witnesses are enough.

Can a notary refuse to notarize a document?

Yes. A notary can refuse if you don't have proper ID, if they don't believe you understand what you're signing, if the document appears to be blank or altered, or if they suspect fraud. A notary can also refuse on personal or religious grounds in some states. If one notary refuses, you can ask another.

How long does a notarization last?

A notarized document doesn't expire. The notary's stamp and signature prove that the notarization happened on that date, and that proof remains valid forever. However, the ID you used to get notarized may expire, and some organizations might ask for a fresh notarization if your ID is very old.
