Instructing an immigration expert witness requires a clear letter of instruction, complete document bundle, realistic timeline, and — for Legal Aid cases — prior authority from the Legal Aid Agency. The letter should set out the specific issues for expert analysis, identify assumed facts, state the tribunal deadline, and confirm funding arrangements.
Provide all relevant documents: witness statements, Home Office refusal letter, CPIN, previous determinations, country guidance decisions, and any prior expert evidence. The expert must distinguish between assumed facts and independent analysis — a requirement reinforced by the Adam Pipe October 2025 guidance.
Expert selection should match witness discipline to case issues: country condition for ground-level analysis, persecution for Convention nexus, human rights for Article 3, linguistic identity for nationality disputes. Use the network directory to route to jurisdiction-specific witnesses.
Instruct as early as possible. Expert reports require research time, and tribunal exchange deadlines under the Practice Direction 2024 are strict. Late instruction risks non-compliance, refusal of late evidence, or reduced weight at hearing.
