Legal practitioners in the UK increasingly face risks from AI-generated fabrications, plausible synthetic text, and hallucinated citations within court submissions and disclosed evidence. Because text-based AI detectors are inherently unreliable, establishing authenticity requires a rigorous return to document provenance analysis rather than relying on linguistic scanning alone. Prepared by the e-Discovery team at Computer Forensics Lab, this work provides UK lawyers with practical forensic strategies to evaluate metadata, inspect native files, and trace corroborating digital footprints across author systems, email servers, cloud environments, and application databases. The text covers the deployment of AI-assisted material, common technical limitations, and professional duties surrounding fabricated evidence. It equips practitioners with worked examples, red flag checklists, and draft questions to put to clients, opponents, and forensic service providers. By detailing clear instruction wording for document provenance examinations aligned with ISO 17025 procedures, it establishes how legal teams can effectively verify genuine documents, expose invented authorities, and determine precisely when to instruct a specialist digital forensics laboratory for expert examination.

§ 01 · ORIENTATION Executive summary The headline point: AI can now fabricate a plausible document in seconds, but detecting AI from the text alone is unreliable, so the forensic answer is not a detector but provenance: where the document actually came support its claimed origin.

§ 13 · COMMON QUESTIONS Frequently asked questions Can you tell if a document was written by AI? How do you prove a document is fabricated? Why do we need the native file and not a printout? Our opponent's submissions cite cases we cannot find. What does that mean? Can metadata itself be faked? Is using AI to draft documents a problem in itself?
