Questioned document examination
examination of documents potentially disputed in a court of law

In forensic science, questioned document examination (QDE) is the examination of documents potentially disputed in a court of law. Its primary purpose is to provide evidence about a suspicious or questionable document using scientific processes and methods. Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court.
Overview
Many QDE involve a comparison of the questioned document, or components of the document, to a set of known standards. The most common type of examination involves handwriting wherein the examiner tries to address concerns about potential authorship.
A document examiner is often asked to determine if a questioned item originated from the same source as the known item(s), then present their opinion on the matter in court as an expert witness. Other common tasks include determining what has happened to a document, determining when a document was produced, or deciphering information on the document that has been obscured, obliterated, or erased.
The discipline is known by many names including "forensic document examination", "document examination", "diplomatics", "handwriting examination", or sometimes "handwriting analysis", although the latter term is not often used as it may be confused with graphology. Likewise a forensic document examiner (FDE) is not to be confused with a graphologist, and vice versa.
Many FDEs receive extensive training in all of the aspects of the discipline.

Why this record matters
The subject matters to the history & society register because the source frames it as examination of documents potentially disputed in a court of law. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q11602707. None of the 0 selected statements returned an explicit reference.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
