A notary is a person authorised to perform acts in legal affairs, in particular witnessing signatures on documents. The form that the notarial profession takes varies with local legal systems.

A notary, while a legal professional, is distinct from an advocate in that they do not represent the person who engages their services, or act in contentious matters.
