Forensic Document Examination * is a forensic science discipline in which expert examiners evaluate disputed documents in the legal system. The forensic document examiner may establish that a document is genuine, can identify or exclude persons who wrote the documents, may identify the source of machine-produced documents, and can restore the legibility of documents. Documents such as fraudulent checks, counterfeit currency, ransom notes, bank robbery notes, suicide notes, contested wills, forged contracts, and fake passports are all examples of different types of evidence that may be collected at a crime scene and submitted to the forensic document examiner.
