What Documents Need to Be Notarized? A Complete NYC Guide

Not every piece of paper needs a notary, but a surprising number of important ones do. In short, a document needs to be notarized whenever a law, institution, or other party requires proof that a signature is genuine and signed willingly. Below are the documents that most commonly need notarization in New York, and how to get it done wherever you are in the city.

Rule of thumb: if a document is legally significant, involves property or money, or will be submitted to a court, bank, or government office, it probably needs to be notarized.

1 What notarization does

A notary public is a state-commissioned official who verifies the identity of the signer, confirms they are signing willingly, and witnesses the signature. That extra layer of trust is why so many institutions require it. The notary does not read or judge the content of your document, only the signing.

No. Only the signatures a law or institution requires to be notarized. When in doubt, ask the party requesting the document.

What do I need to bring?

A valid, unexpired government photo ID, and the unsigned document. Do not sign it beforehand if notarization is required, you sign in front of the notary.
