What does it mean for a notary to witness a signature? A: If a notary is asked to witness a signature, the notary simply observes an individual signing a specified document, according to the American Society of Notaries. Documents that can be witnessed by a notary do not require an oath or affirmation.
A certifying official may also attest to the legal correctness and authenticity of a document by signing his or her name to it. This is usually done when copies of documents that required witness signings must be made.
