There are several types of notaries in the United States, and they mostly differ in two ways: how they meet with you and what they specialize in. The common categories are the standard notary public, the mobile notary who travels to you, the electronic notary who works with digital documents in person, the remote online notary who handles everything over video, and the notary signing agent who focuses on loan closings. A separate term, civil law notary, means something very different outside the U.S. and is a frequent source of confusion.
The Standard Notary Public
Every other type on this list is built on this one. A standard notary public is a state-commissioned officer authorized to perform a short list of acts: taking acknowledgments, administering oaths and affirmations, witnessing signatures, and certifying copies of certain documents.
The role is ministerial, which means the notary follows a set procedure instead of exercising judgment about what the document says. Their job is to confirm the signer is who they claim to be, is signing voluntarily, and has at least a basic awareness of the document. Identity is typically verified with a government-issued photo ID. Fees for a single notarial act are capped by state law and generally run from a few dollars up to $25 or more in some states.
When people picture “getting something notarized” at a bank, shipping store, or law office, this is the type they’re picturing. If your document doesn’t involve a loan closing, special technology, or an unusual location, this is almost always the notary you need.
Mobile Notaries
A mobile notary holds the same standard commission as any other notary public. The difference is logistical: they travel to you instead of working from a fixed office. You can arrange one to meet at your home, a hospital room, a business office, or wherever is convenient.
This matters most for elderly or homebound people, hospital patients, and anyone facing a deadline who can’t reach a notary during business hours. Expect a travel fee on top of the standard notarization charge. Travel fees are not always capped by state law the way per-act notarization fees are, so ask for the total cost before booking.
Electronic Notaries
Electronic notarization, or e-notarization, works like a traditional notarization except the document and the notary’s seal are digital rather than paper. The signer still appears in person. Both parties apply electronic signatures, and the notary attaches a tamper-evident electronic seal that flags any unauthorized changes made to the document after signing.1National Association of Secretaries of State. Remote Electronic Notarization
The practical advantage is speed and record-keeping. Digital documents are easier to store, search, and transmit, and the tamper-evident seal creates a built-in audit trail. Think of e-notarization as the same meeting you’d have with a traditional notary, just conducted on a screen instead of on paper.
Remote Online Notaries
Remote online notarization, usually called RON, removes the in-person requirement entirely. The signer and the notary connect through a live audio-video call from different locations. Virginia pioneered this in 2011, and roughly 38 states have since enacted RON laws.1National Association of Secretaries of State. Remote Electronic Notarization
Because there’s no face-to-face meeting, RON uses layered identity verification. You typically present a government-issued ID on camera for credential analysis, then answer a timed quiz of five personal questions pulled from public and credit records. Most states require at least four correct answers within two minutes and allow only two attempts in a 24-hour period before a waiting period kicks in. The session itself is recorded, and states generally require those recordings to be stored securely for five to ten years.
RON is especially useful for real estate closings where the parties live in different states, for overseas military personnel, and for anyone who can’t easily travel. One caution: interstate recognition isn’t uniform. A RON performed under one state’s law isn’t automatically accepted everywhere. The SECURE Notarization Act, which would require nationwide recognition, passed the U.S. House in 2023 but stalled in the Senate.2Congress.gov. H.R.1059 – 118th Congress (2023-2024): SECURE Notarization Act Until something like it becomes law, check that both states involved in your transaction will accept the notarization.
Notary Signing Agents
A notary signing agent is a commissioned notary public who specializes in loan document signings, most often for real estate transactions. The title company or lender hires the agent to meet with the borrower, walk them through the loan package, witness signatures, and make sure every page is properly executed and returned.
The legal authority is the same as any other notary’s, but the role takes extra training because a mortgage loan package can run 100 pages or more. Most title companies and signing services require certification and an annual background screening covering criminal records, motor vehicle records, and watch list databases.3National Notary Association. Notary Signing Agent Background Screenings
Here’s the limit that trips borrowers up at the closing table: a signing agent cannot explain the legal or financial terms of the loan. If you ask what an adjustable rate means or whether a prepayment penalty applies, the agent has to send you back to the lender or your attorney. Answering those questions would be the unauthorized practice of law. The agent is there to handle the notarization and the paperwork logistics, not to advise you.
Civil Law Notaries and the “Notario” Warning
Outside the U.S., the word “notary” often means something very different. In civil law countries across continental Europe, Latin America, and parts of Asia, a civil law notary is a highly trained legal professional who typically holds a law degree and has passed additional qualifying exams. Their authority goes well beyond witnessing signatures: they draft contracts, authenticate wills, handle real estate transfers, and advise parties on legal implications. The documents they authenticate carry the weight of public records.
The closest U.S. equivalent exists in only a few states. Florida and Louisiana, for example, recognize a form of civil law notary with expanded authority rooted in those states’ historical ties to continental legal traditions. Everywhere else in the country, a notary public cannot draft legal documents or offer legal opinions.
That gap has created a specific consumer fraud problem the Federal Trade Commission has repeatedly warned about. In many Latin American countries, a “notario público” is the highly trained legal professional described above. Some people in the United States exploit that understanding by advertising themselves as “notarios” to Spanish-speaking immigrants, implying they can help with immigration cases or represent clients before government agencies. They can’t. A notario in the U.S. is at most a standard notary public with no authority to provide legal services. The FTC reports that victims lose money and time to these scams, and botched immigration filings can actually damage a person’s ability to obtain lawful status.4Federal Trade Commission. Notarios Are No Help With Immigration Only licensed attorneys and Department of Justice-accredited representatives can legally provide immigration help.
What No Notary Can Do
Whichever type you choose, the limits are the same. A notary who isn’t also a licensed attorney cannot give legal advice, explain the meaning of a document, or help you fill in blanks on a legal form. That falls under the unauthorized practice of law, and the penalties can include criminal prosecution, civil liability, and loss of the commission.
A few other rules apply across the board:
- A notary cannot notarize a document unless the signer appears before them in person or, for RON, on a live video connection. Stamping a document without the signer present is fraud.
- A notary must refuse a document with blank spaces or missing pages that should have been completed before signing.5American Society of Notaries. Prohibited Notarial Acts
- The notarial certificate must show the actual date of the notarization. Backdating or post-dating is prohibited.5American Society of Notaries. Prohibited Notarial Acts
- A notary generally cannot notarize a document in which they are a named party to the transaction.
Pick the type based on your situation. For a routine signature, a standard notary at a bank or shipping store is fine. For someone who can’t travel, call a mobile notary. For a fully digital workflow with the signer present, look for an electronic notary; for a signing across distance, look for a RON provider licensed in a state your transaction will accept. For a mortgage or real estate closing, the title company will typically arrange a signing agent. And if someone offering immigration help calls themselves a notario rather than an attorney, that alone is reason to walk away.
