Forensic Document Examination is a scientific process used to analyze documents to determine their authenticity and origin. This field involves examining handwriting, ink, paper, and printing techniques to identify alterations, forgeries, or other irregularities. Forensic document examiners often work with law enforcement agencies to provide expert testimony in legal cases. The examination process may include comparing known samples of handwriting with questioned documents, analyzing the physical properties of materials, and using specialized tools like microscopes and ultraviolet light. This discipline plays a crucial role in criminal investigations, fraud cases, and disputes involving contracts or wills.
