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.
Many QD examinations 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.

The visual appearance of inks is only one clue to their composition. Sometimes two inks can look identical to the naked eye but further tests may be able to distinguish between them. Where possible non-destructive tests are used. For example inks can be examined using infra red or ultraviolet reflectance at various wavelengths or using visible light but examining emissions from the ink in the infra red area of the spectrum infra red luminescence. Our examiners use an instrument known as a VSC HR to carry out non-destructive specialised lighting examinations.
Inks may also be distinguished by other more complex chemical tests but these are likely to be destructive to some extent. Differentiating inks can be important in cases where a document is suspected of having been altered.
