Questions to Ask a Medical Expert Witness at Deposition

By John Mahoney · Updated 2026-09-01 · 23 specialties

Here is the problem nobody says out loud: you are going to cross-examine a physician about medicine, and you never went to medical school. In a multi-defendant malpractice case it is worse — a single case routinely involves two, three, or four different specialties, each with its own expert, its own literature, and its own vocabulary. You cannot become a cardiologist and a radiologist and an intensivist by deposition day.

What you can do is bring structure. Every guide below is built around concession funnels: chains of leading, one-fact questions that start from propositions no credible expert can refuse and narrow, answer by answer, toward the commitments your case needs. Each guide covers qualifications and scope, the bases-of-opinion lockdown, the specialty's substantive concession chain, closing-the-doors questions — and the classic traps lawyers fall into with that specialty.

Pick the specialty you're deposing

These are the generic questions. Your case isn't generic.

The MedLegal AI Examination Builder generates a complete, case-specific concession-funnel roadmap for deposing any medical expert — built from your theory of the case, aware of which side you're on and what kind of witness you're facing, with stop markers, if-they-resist branches, and the doors you should not open. Three free cases, no credit card.
