Notary public: what it means

In the United States, a notary public is a person authorized by law to administer oaths and witness signatures on legal documents; the notary verifies who is signing and certifies the signature. The rules for becoming a notary vary by state.

In Spanish it is

Notario público (notary public)

Also written as: notary

The full explanation

It is not the same as a "notario público" in many Latin American countries, where the title means someone with the equivalent of a law license. Here, a notary who is not a lawyer cannot give you legal advice or help you with immigration paperwork. Some states, such as Oregon, forbid them from advertising as a "notario" or "notario público".

An example

At closing, Pedro signs his deed of trust in front of a notary, who verifies his identity and signature. When a neighbor recommends a "notario" for his immigration case, Pedro remembers that in the United States a notary is not a lawyer and looks for authorized help instead.

You will see it in…

  • Documents you sign at closing, such as the deed of trust
  • “Notario” ads that offer help with immigration paperwork
  • A notary's signature and stamp on legal documents

Words that go with it

You will rarely see this word alone. These are the ones that show up with it on the same papers.
