Dating: documents

From its beginning, the field of questioned documents has been concerned with dating. Proposed methods usually lean upon complex processes, and controversy among the scientific community is still high. Every document dating method whose objective is to be applied in forensic caseworks must fulfill validation requirements. Moreover, source inference must also be taken into account in the interpretation of the dating evidence. To date, most methods still fail to be adequately validated, and should be applied with extreme caution. The limitations of the methods used must be adequately disclosed and documented.
