What does a forensic document examiner do?
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.
Forensic document examiners are trained to identify alterations to documents. This includes changing text, finding erasures, determining whether a page in a set of documents was substituted and discovering that an electronic document such as a PDF file has been changed.
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.
