Forensic Document Examination is a scientific discipline dedicated to the analysis of documents to verify their authenticity, detect forgery or tampering, and identify the authorship of handwriting or signatures. This specialized field involves the detailed scrutiny of handwriting, signatures, typewriting, printed materials, alterations, erasures, paper, ink, and other document characteristics using specialized equipment and methodologies. It plays a crucial role in civil, criminal, and commercial investigations.
A Forensic Document Examiner (FDE) is a trained expert who applies scientific techniques to examine questioned documents. The examiner provides independent and unbiased opinions on matters such as signature authenticity, handwriting authorship, document alteration, counterfeit detection, and other issues involving written or printed materials. These expert findings are often used in court as admissible evidence to assist judges, lawyers, and investigators in reaching just conclusions.

Our goal is to assist clients in uncovering the truth behind questionable documentation and provide expert opinions that stand up to scrutiny in both civil and criminal proceedings.
