A forensic document examiner (also called questioned document examiner) determines the authenticity of a questioned document. A forensic document examiner can state that questioned documents were either written by or not written by the person who wrote the known writing.

A forensic document examiner will not determine that questioned documents are a forgery. Forgery implies another person wrote or signed a document using another person's name or writing with the intent to harm the other person. A document examiner does not determine state of mind nor intent of a writer.
