Prepare an authenticity challenge or an expert-instruction letter

Key facts

Human involvement: RedLawyer-led
How AI is used: Index the exhibit, the foundation the proponent offers, and the gaps. Write no sentence of the motion, the brief, the expert letter, or any other paper that will be filed or sent.
What the lawyer must review: You write the challenge. Rule 11(b) is your certification of the legal and factual contentions. An expert on fabrication or a process must meet Rule 702: the opinion must be more likely than not based on sufficient facts, reliable principles and methods, and a reliable application. Rule 3.3 requires you to correct a false statement of fact or law, including one that came from a tool. Formal Opinion 512: review citations and analysis before they go to a court.

Who does what

Role	What they do
Assistance	Supporting preparation only. Potential support includes extracting and organising information. Confirm the tool’s capability and permitted scope. The tool writes nothing into the document. Substantive advice, judgement and any restricted content remain with the responsible human.
Lawyer	Perform the substantive analysis and decisions. Independently check any permitted supporting work and approve the exact output for its intended use.

Open each relied-on authority independently. Confirm its existence, current status, proposition and any quotation or pinpoint reference.
Check the specialist’s assumptions, qualifications and limits. Obtain the relevant expert or specialist review before relying on a technical conclusion.
Preserve original files and relevant metadata. Document provenance and handling, and seek forensic review where authenticity needs to be resolved.
Confirm the output against the client’s instructions and the complete relevant source material, including omissions or contradictions.
Resolve exceptions and record the responsible lawyer’s approval of the exact output and intended use.
