A notary public is a state-appointed, impartial official who verifies identity and witnesses the signing of important documents to help prevent fraud. When a notary stamps your document, they are confirming that you are who you say you are, that you signed willingly, and that the signing really happened. That simple act gives documents legal weight and trust. Here is what a notary actually does, what they cannot do, and how to use one in New York.
1 What a notary does
A notary’s core job is to be a neutral witness who protects against fraud. In practice, they:
- Verify identity. They check your valid, unexpired government photo ID.
- Witness the signature. You sign in front of them, not before.
- Confirm willingness. They make sure you are signing freely and appear to understand.
- Apply the stamp and record it. The seal and their journal make it official.
Common documents that need a notary include affidavits, powers of attorney, deeds and real estate papers, consent forms, and many legal and financial documents.
2 What a notary cannot do
Just as important is what a notary is not. A notary is not a lawyer and cannot give legal advice, cannot tell you what to write, and cannot decide whether your document is valid or wise. They also cannot notarize a document if you are not present, if your ID is missing or expired, or if you seem confused or pressured. Their role is to witness, not to judge the content.
3 Types of notary service
You can reach a notary three ways: go to one in person (a bank, shipping store, or office), have a mobile notary come to you, or use a remote online notary who handles it over secure video. The right choice depends on whether you can travel and how fast you need it.
4 What it costs in NY
New York caps the notarial act at $2 per signature in person, or up to $25 per act for remote online notarization. A mobile notary adds a travel fee for coming to you, which is agreed in advance. For a full breakdown, read how much a notary costs in NY.
5 How to use one
Bring your unsigned document and a valid photo ID, meet the notary in person or online, sign in front of them, and they verify, witness, and stamp. That’s it. If you need a notary in NYC, in person, mobile, or online, we cover all three.

What a notary is not
The confusion is widespread and, in some communities, actively exploited.
A notary public in the United States is not a lawyer. In many Latin American countries a notario público is a licensed attorney with far broader authority, and people who arrive expecting that are vulnerable to anybody willing to blur the difference.
A New York notary may not give legal advice, select a document for you, draft one, explain what a document does, or represent anyone before an agency. Anybody offering those services under the notary label is practising law without a license.
What a notary actually certifies
That a person appeared, was identified in the manner the law requires, and signed or swore to the document. Nothing more.
Not that the contents are true. Not that the document is lawful or enforceable. Not that the signer owns what they claim to own or has authority to act for anyone. Any recipient reading a notarized document should evaluate it on its own merits rather than treating the seal as verification of what it says.
The two certificates, and why it matters which
An acknowledgment confirms you signed voluntarily. A jurat confirms you swore the contents are true, and it is what affidavits require.
Choosing between them is a legal decision, so a notary cannot choose for you. Ask the party receiving the document which they need. Using the wrong one is a substantive defect rather than a formatting preference, and it is a common reason filings are rejected.
What New York notaries may charge
The fees are set by statute and they are low. $2 per signature for a traditional in person notarization, and up to $25 per notarial act for electronic notarization, a figure the statute specifies is inclusive of all costs incurred by the notary.
That is why almost nobody makes a living from notarial fees alone. What people pay for is the travel, the availability at nine in the evening, and the willingness to handle a document a bank branch would decline. A mobile fee is not a notary fee, it is a fee for coming to you.
When a notary must refuse
A notary is required to decline in several situations, and understanding them prevents an argument at the table.
If the signer cannot be identified with acceptable unexpired identification. If the signer does not appear to understand what they are signing. If the signer seems to be acting under pressure rather than freely. If the signer is not present, in person or by approved video. If the document is incomplete, with blanks that could be filled in afterwards. Or if the notary has a personal interest in the transaction.
None of those are the notary being difficult. Each one is the reason the document still stands when a bank or a court examines it later.
The journal, and why it matters to you
New York notaries keep a record of notarial acts, and for electronic notarizations the session itself is recorded and retained.
That record protects the signer as much as the notary. If somebody later questions whether you signed, or claims a signature was forged, the journal entry and, for online sessions, the recording are what answer it. It is also why a notarization can be produced under subpoena, which is worth knowing before rather than after.
