What Is a Notary? What They Do and How Notarization Works in 2026

A notary public is an official authorized by a state government to serve as an impartial witness to the signing of important documents. The notary verifies the identity of the people signing, confirms they're signing willingly and knowingly, witnesses the signature, and then applies an official seal or stamp, making the document "notarized." The purpose is to deter fraud and add a layer of legal credibility, so that anyone relying on the document can trust the signatures are genuine. And as of 2026, notarization no longer always requires meeting in person, most states now allow it to happen over a live video call.

That's the core of it. Notaries show up across estate planning and ordinary life, on powers of attorney, deeds, affidavits, and countless other documents, so understanding what they actually do and how the process works (including the online option) is genuinely useful. Here's the full picture.

What a notary actually does

The notary's role is narrower and more specific than people often assume. A notary doesn't give legal advice, doesn't vouch for the content of a document, and doesn't confirm that a document is true or fair. What a notary does is authenticate the signing, and that authentication has a few specific components.

First, the notary verifies the signer's identity, typically by checking a government-issued photo ID, to confirm the person signing is who they claim to be. This is the heart of the notary's anti-fraud function: making sure someone can't sign a document in another person's name. Second, the notary confirms the signer is acting willingly and appears to understand what they're signing, that they're not being coerced and aren't obviously incapacitated. Third, the notary witnesses the actual signing, observing the person sign the document (or acknowledge a signature already made). Fourth, the notary completes a notarial certificate and applies their official seal or stamp and signature, which is what makes the document notarized.

What the notary is not doing is just as important. The notary doesn't read or evaluate the document's contents, doesn't confirm it's legally sound, and doesn't provide any legal opinion. A notarized signature means "this person, whose identity was verified, signed this willingly in front of a notary," not "this document is valid or true." Understanding that boundary clears up a common misconception: notarization authenticates the act of signing, not the substance of what was signed.

What "notarized" means

When a document is "notarized," it means a notary public has performed this verification and witnessing process and applied their seal. The notarization is evidence that the signature is authentic, that the named person actually signed, with their identity confirmed, on the date indicated, in the notary's presence.

This added credibility matters because many important documents are required by law or by the parties relying on them to be notarized before they're accepted. Notarization makes a document harder to challenge on the grounds that the signature was forged or that the signer didn't really sign, because there's an official, impartial witness attesting to the signing. It's why notarization is required or recommended for documents where authenticity is critical: real estate deeds, powers of attorney, certain affidavits, and many estate-planning documents.

There are a couple of distinct notarial acts worth knowing. An "acknowledgment" is where the signer appears before the notary and acknowledges that they signed the document, used for things like deeds and powers of attorney. A "jurat" is where the signer swears or affirms that the contents of a document are true and signs in the notary's presence, used for affidavits and sworn statements. The notary administers the oath in a jurat. The difference matters for legal purposes, but for most people the practical experience, show ID, sign in front of the notary, get the stamp, is similar.

How notarization works, step by step

Getting something notarized traditionally follows a simple process. You bring the unsigned document and your valid government-issued photo ID to a notary, you might find one at a bank, a shipping store, a law office, or through a mobile notary who travels to you. The notary verifies your identity against your ID. You sign the document in the notary's presence (or acknowledge your signature, depending on the act). The notary completes the notarial certificate, applies their seal and signature, and records the act in their journal. That's it, the document is now notarized.

A key rule: you generally should not sign the document before you get to the notary, because for many notarial acts the notary needs to witness the signing itself. Bring it unsigned and sign in front of them. Notaries also charge a fee for their service, often a modest amount set or capped by state law, though mobile and specialized notaries may charge more for convenience or travel.

Remote online notarization: notarizing over video

The biggest change in notarization in recent years is that you can now get many documents notarized entirely online, without leaving home. This is called remote online notarization (RON), and it's gone from a novelty to the norm.

With remote online notarization, you and the notary meet over a live, secure audio-video connection. The notary verifies your identity remotely, often through a combination of ID verification technology and knowledge-based authentication questions, watches you sign electronically, and applies an electronic notarial seal. The entire process happens over video, and the notary and signer don't need to be in the same room or even the same state.

As of 2026, remote online notarization is permanently authorized in 49 states plus the District of Columbia, with California the lone holdout for full permanent RON, where it's set to take effect in 2030 and a limited pilot operates in the meantime. Virginia was the first state to permanently authorize it back in 2012, and adoption accelerated dramatically after 2020. For most people in most states, RON is now a genuine option, letting you handle a notarization from your couch in minutes instead of hunting for a "notary near me."

There are important limits, though, and they matter especially for estate planning. Permanent RON authorization doesn't mean every document type can be notarized online. Many states specifically exclude certain documents from remote notarization, and wills, trusts, and codicils are often on the excluded list. So even where RON is broadly legal, your last will or living trust may still need to be notarized (and witnessed) in person under your state's rules. Real estate documents also have varying rules. And rules differ on whether a notary in one state can notarize for a signer located in another. The bottom line: remote notarization is widely available and convenient for many documents, but for estate-planning documents specifically, check whether your state allows them to be notarized online before assuming you can skip the in-person appointment. The National Association of Secretaries of State tracks notarization and RON developments across the states.

When you need a notary

Notarization comes up more than people expect, particularly in estate planning and major transactions. Documents that commonly require or benefit from notarization include real estate deeds and property transfers, powers of attorney, which usually must be notarized to be accepted by banks and other institutions, certain affidavits and sworn statements, some living wills and advance directives depending on the state, and various financial and legal documents.

For estate-planning documents in particular, notarization (and proper witnessing) is often what makes the difference between a document that's honored and one that's challenged or rejected. Many states have specific signing requirements for wills, trusts, and powers of attorney, including notarization, witnesses, or both, and meeting those requirements exactly is what makes the documents valid and enforceable. Because the rules vary by state and by document, confirming the specific notarization and witnessing requirements for your state is a worthwhile step when finalizing any important document.

Frequently asked questions

What does notarized mean?

A document is notarized when a notary public has verified the signer's identity, witnessed them sign it willingly, and applied an official seal or stamp. Notarization is evidence that the signature is genuine, that the named person actually signed, with their identity confirmed, in the notary's presence. It doesn't certify that the document's contents are true or legally valid; it authenticates the act of signing, adding credibility and making the signature harder to challenge as a forgery.

Can you get a document notarized online?

Yes, in most states. Remote online notarization (RON) lets you get many documents notarized over a live video call, with the notary verifying your identity and witnessing your electronic signature remotely. As of 2026, RON is permanently authorized in 49 states plus DC, with California the remaining holdout until 2030. However, some document types, often including wills, trusts, and codicils, are excluded from remote notarization in many states, so check whether your specific document qualifies before relying on the online option.

What's the difference between a notary and a lawyer?

A notary public verifies identities and witnesses signatures to authenticate documents, but does not give legal advice, draft documents, or evaluate whether a document is legally sound. A lawyer provides legal advice, drafts and reviews documents, and represents clients. A notary's role is narrow, confirming who signed and that they signed willingly, while a lawyer's role involves the substance of legal matters. Some lawyers are also notaries, but the two functions are distinct.

A notary public plays a small but important role in making documents trustworthy, and with remote online notarization now widely available, getting something notarized is easier than ever, as long as you check that your particular document, especially estate-planning documents, qualifies for the method you want to use.
