What does evidence of questioned documents typically involve?

Evidence of questioned documents typically involves transactions and personal information records because these types of documents can be analyzed to determine authenticity or to identify alterations and forgeries. Analyzing questioned documents often includes examining features such as handwriting, printing, ink types, and paper quality. Documents that record transactions, such as contracts, receipts, and identification papers, provide vital context for investigations involving fraud or identity theft. When examining these records, forensic document examiners seek to establish the legitimacy and integrity of the documents in relation to the claims being made, which is the cornerstone of questioned document analysis.

The other options, while they may play roles in different contexts, do not center on the primary elements involved in questioned document analysis. Monitoring environmental changes may relate to circumstances affecting the creation of documents but is not directly part of analyzing the documents themselves. Measurements of physical items pertain more to forensic evidence rather than document examination. Witness statements are essential in many types of cases but do not constitute the direct evidence that questioned document analysis focuses on.
