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.
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.
