In forensic document examination, experts analyze documents to determine whether they are genuine or forged. Such documents are called
questioned documents.
These documents may include:
- Handwritten notes
- Signatures
- Contracts
- Printed documents
- Cheques and legal papers
Step 1: Understanding the meaning of a questioned document.
A
questioned document refers to any document whose origin, authorship, or genuineness is disputed or uncertain during an investigation.

In forensic science, the main reason a document becomes questioned is because its
authenticity is doubtful. Experts analyze handwriting, ink, paper, printing methods, and alterations to determine whether the document is genuine.
