Oral evidence allows cross-examination and concurrent evidence (hot-tubbing) where directed. Attendance fees are separate from report preparation and require LAA prior authority in legally aided cases.
Experts must know their report thoroughly, maintain independence under challenge, and distinguish assumed facts from expert opinion per the Adam Pipe October 2025 guide.
