What Is a Notary Public? Duties & Expectations

What Is a Notary Public? Definition, Duties, and What to Expect (2026)

Jessica's first apartment in Houston came with a lease longer than her college thesis. She signed every page, initialed the pet addendum, and emailed it back to the property manager. The reply came an hour later:

"Thanks, Jessica. Please have the lease notarized and return the original."

Jessica stared at the word. Notarized. She had seen it on TV — usually in scenes with stern men in suits and leather-bound books — but she had no idea what it actually meant, where to find one, or why her lease suddenly needed it. She was too embarrassed to ask her landlord what felt like a basic question, so she texted her older brother, a real estate agent in Dallas.

"A notary is just a person who watches you sign stuff and stamps it," he replied. "Go to a UPS Store. Costs like ten bucks."

That answer was technically true and practically useless. Jessica's visit to the notary raised a dozen questions her brother's text didn't answer. This guide is everything Jessica wishes she had known before walking into that UPS Store — and everything you need to know if you're staring at the word notarized for the first time.

What Is a Notary Public? (The Actual Definition)

A notary public is a state-commissioned official who acts as an impartial witness to the signing of important documents. Their primary purpose is to deter fraud by verifying that signers are who they claim to be, that they are signing voluntarily, and that they understand what they are signing.

Here is the critical part: a notary does not verify that the content of your document is true or legal. They verify the act of signing — your identity, your awareness, and your willingness.

Think of a notary as a fraud-prevention checkpoint, not a legal advisor. They are appointed by the state government (in Texas, by the Secretary of State) and are legally empowered to:

• Witness signatures on documents
• Administer oaths and affirmations
• Take acknowledgments (confirming you signed a document willingly)
• Certify copies of certain documents
• Record each notarization in an official journal

What Does a Notary Actually Do? Jessica's Appointment Explained

Jessica walked into a shipping store with her unsigned lease and her driver's license. Twenty minutes later, she walked out with a notarized document and a much clearer understanding of the process. Here is what happened step by step:

Step 1: Identity verification. The notary asked for Jessica's government-issued photo ID — her Texas driver's license. She compared the photo to Jessica's face, checked that the license was not expired, and recorded the ID number in her journal.

Step 2: Confirming willingness and awareness. The notary asked Jessica two questions: "Are you signing this document of your own free will?" and "Do you understand what this document says?" Jessica said yes to both. The notary was not checking whether Jessica had read every clause — only that Jessica was not being forced to sign and was not obviously confused about what she was doing.

Step 3: Witnessing the signature. Jessica signed the lease in the notary's physical presence. If Jessica had signed beforehand, the notary would have made her sign again — the notary must see the signature happen.

Step 4: Completing the notarial certificate. The notary filled out a section at the end of the lease — called a notary certificate or notary block — with the date, her name, her commission number, and the location. She signed it and stamped it with her official seal.

Total time: 12 minutes. Total cost: $15.

What a Notary Is NOT (Jessica Almost Learned This the Hard Way)

While waiting, Jessica asked the notary a question that made her wince in retrospect: "This lease says I can't have guests after 10 PM. That seems illegal, right? Can you just take that part out?"

The notary smiled and said, "I can't give legal advice or change your document. I can only witness your signature. If you have concerns about the lease terms, you should talk to a lawyer before signing."

Here is what notaries cannot do, no matter how helpful they seem:

• Give legal advice or interpret documents for you
• Prepare documents or fill them out on your behalf
• Notarize incomplete documents or documents with blank spaces
• Notarize if you are not present (in person or on video for remote online notarization)
• Certify copies of vital records like birth certificates, death certificates, or marriage licenses — only the issuing agency can do that
• Notarize their own signature or notarize for immediate family members (in most states, including Texas)

If a notary offers to "help you understand" your contract, that is a red flag. A professional notary will refer you to an attorney.

Types of Notaries: Not All Stamps Are the Same

Jessica's brother mentioned UPS Stores because they are the most visible type of notary — the traditional, in-person notary who works from a fixed location. But notaries come in several forms, and the right one depends on your situation.

Traditional Notary

Works from a bank, shipping store, law office, or government building. You travel to them during business hours. Best for simple, non-urgent documents. Cost: $5–$15 per signature in Texas.

Mobile Notary

Travels to your home, office, hospital, or coffee shop. Ideal for urgent needs, after-hours appointments, or signers who cannot travel. Cost: $50–$150 including travel fees. See the Texas mobile notary pricing guide for details.

Remote Online Notary (RON)

Notarizes documents via secure video conference. You upload your document, verify your identity through knowledge-based questions and ID scanning, and sign electronically while the notary watches on video. Legal in Texas since 2018. Cost: $25–$50. See our Texas RON guide.

Notary Signing Agent

A notary with additional training in real estate and loan documents. Handles mortgage closings, refinances, and property transfers. Fees are higher ($75–$250) because the document packages are complex and the stakes are high. Learn more about real estate notaries.

Why Do Documents Need to Be Notarized?

Jessica's lease needed notarization because it was a high-value contract — a one-year commitment with significant financial and legal obligations. Notarization serves three purposes:

Fraud prevention. By verifying identity and witnessing the signature, a notary makes it extremely difficult for someone to forge your signature or impersonate you in a legal transaction.

Evidence of validity. A notarized document carries a presumption of authenticity in court. If there is ever a dispute about whether you signed something, the notary's journal and certificate provide independent evidence.

Legal requirement. Some documents are simply not valid without notarization. Powers of attorney, deeds, mortgage documents, and articles of incorporation are typically rejected by courts and government agencies unless properly notarized.

Not every document needs notarization. Your grocery receipt does not need a stamp. But any document that creates a legal obligation, transfers property, or makes a sworn statement probably does. See our complete guide to which documents need notarization.

What to Bring to a Notary Appointment

Jessica was prepared, but many first-timers are not. Here is what you need:

• Valid government-issued photo ID. Driver's license, passport, or state ID. The name must match the document exactly. Expired IDs are not accepted.
• The document, unsigned. Do not sign it beforehand. The notary must witness the signature.
• Payment. Cash, check, or card — confirm accepted methods before you arrive.
• Witnesses, if required. Some documents (like wills in Texas) require witnesses in addition to a notary. The notary cannot serve as a witness.
• Completed blanks. Fill in every blank space on the document or cross out unused lines. Notaries cannot notarize documents with blank spaces.

How to Find a Notary Near You

If you are in Texas, you have several options:

1. Banks and credit unions. Many offer free notarization for account holders.
2. Shipping stores. UPS Stores, FedEx locations, and similar chains often have a notary on staff.
3. Online search. Search "notary near me" or browse by city on NotaryHub to submit a Texas notary request.
4. Remote online. For qualifying documents, RON platforms may connect you with a Texas-commissioned notary without leaving your home.

What Does It Cost to Get Something Notarized?

Texas caps the fee for a standard acknowledgment or jurat at $10 for the first signature and $1 for each additional signature on the same document. That is the state maximum for the notarial act itself.

However, most notaries charge for their time and convenience:

Jessica's Final Takeaway

By the time Jessica returned her notarized lease, she understood something her brother's text had missed: a notary is not just "a person who stamps stuff." A notary is a fraud-prevention professional appointed by the state to protect the integrity of important transactions.

The notary did not read Jessica's lease. She did not advise Jessica on whether the guest policy was fair. But she did confirm that Jessica was who she said she was, that she signed willingly, and that her signature was witnessed by a neutral third party. That $15 stamp made Jessica's lease legally defensible — and gave her landlord the confidence to hand over the keys.
