A Forensic Document Examiner FDE is a forensic scientist who scientifically studies various physical details and elements of documents in order to identify their source or to determine their authenticity or integrity. Document examiners help lawyers by examining and offering written opinions on a variety of disputed document problems.

This knowledge will assist lawyers in preparing meaningful direct examination questions for their own expert witness and cross-examination questions for opposing experts.
