Questions to Ask a Family Medicine Expert Witness at Deposition (2026 Guide)

By John Mahoney · Updated 2026-09-01 · 18 questions in 4 concession chains

You are about to cross-examine someone with two decades of training you don't have, on their home turf, about the thing they do every day. That asymmetry is the defining problem of medical-expert depositions — and it gets worse in multi-defendant malpractice cases, where two to four different specialties can be in play in a single case and you have to be conversant in all of them by deposition day.

Family-medicine experts testify in missed-cancer, delayed-referral, and failed-follow-up cases. The longitudinal record is the plaintiff’s asset — the same complaint appearing visit after visit — and the funnel is built to make the expert read that record as a pattern rather than as isolated encounters.

The answer to the asymmetry is not to learn family medicine — it is structure. A concession funnel asks the expert to agree, one fact at a time, to propositions so orthodox that refusing them costs more credibility than granting them. The questions below are a generic-case-safe starting bank, organized into the four chains that structure works through.

How to use these questions

Every question below follows three rules of expert cross-examination: it is leading (it states a fact and asks for agreement), it contains one fact (no compounds — a compound question lets the witness answer the easy half), and it belongs to a concession chain (each answer narrows the room the next answer can live in). Ask them in order. When you get the concession, stop — do not ask the "why" question that lets the expert explain it away.

Chain 1 — Qualifications, retention & scope

Goal: establish on the record that this is a paid, retained witness who never touched the patient, and fix the boundaries of what they actually practice.

Doctor, you were retained by opposing counsel in this case, correct?
You are being compensated for your time reviewing this case and for your testimony today, correct?
You never examined or treated the patient in this case, correct?
Everything you know about this case comes from the materials counsel selected and sent to you, correct?
Part of the family physician’s role is recognizing when a problem needs a specialist, correct?

Chain 2 — Bases-of-opinion lockdown

Goal: freeze the universe. After this chain, any new document, new basis, or new opinion at trial is impeachment material.

You have now told us every document and material you reviewed in forming your opinions, correct?
You are not relying on anything outside that file for the opinions you will give in this case, correct?
You have told us every opinion you intend to offer at trial, correct?
You agree that an opinion you cannot state to a reasonable degree of medical probability is speculation, correct?

Chain 3 — Substantive concessions: persistence, follow-up, and the longitudinal record

Family medicine’s defining feature — continuity over time — is also what its cases turn on. Each question below converts continuity from a talking point into an obligation.

A persistent symptom that is not improving warrants reassessment, correct?
Reassurance is not a substitute for reassessment, correct?
An abnormal screening result requires follow-up, correct?
A referral that is never completed protects no one — tracking referrals matters, correct?
The chart is the contemporaneous record of what was reported at each visit, correct?
A documented negative finding is different from no documentation at all, correct?

Chain 4 — Closing the doors

Goal: end with the record sealed. These questions convert silence into a commitment that nothing new is coming at trial.

You are not offering any opinions in this case beyond the ones we have discussed today, correct?
You have not held back any opinion or criticism that you intend to offer at trial, correct?
You are not offering any opinion about what the specialists did after the referral was finally made, correct?

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

Where lawyers get burned deposing family medicine experts

Letting "primary care can’t work up everything" answer a specific failure

It is true in general and irrelevant in the case at hand. Concede the generalization, then narrow: this symptom, reported this many times, over this period — and ask what the standard required for that pattern. Generalities cannot answer a pattern question.

Letting the expert fragment the visits

The defense reads each encounter in isolation, where each looks defensible. The case is the sequence. Walk the visits in order, lock what was reported at each, and only then ask the pattern question. An expert who has conceded each data point has conceded the pattern.

Missing the off-chart contacts

Family practices run on phone calls and portal messages that may never make the chart. Ask the expert whether their opinion assumes the chart captures every patient contact — and what happens to that opinion if it does not. It is a foundation crack the defense rarely patches.

FAQ

What questions should I ask a family medicine expert witness at deposition?

Work in four concession chains: (1) qualifications, retention, and scope — establish the expert was retained, is compensated, never treated the patient, and what they do and do not practice; (2) bases-of-opinion lockdown — pin every document reviewed and every opinion they intend to offer; (3) the family medicine-specific substantive chain — well-established propositions such as "A persistent symptom that is not improving warrants reassessment"; and (4) closing the doors — confirm on the record that no undisclosed opinions remain. Every question should be leading, contain one fact, and build on the prior answer.

How do I cross-examine a medical expert when I never went to medical school?

You don't out-doctor the doctor — you build concession chains from propositions so well-established that a credible family medicine expert cannot refuse them, then apply those concessions to the facts in the chart. The expert's medical training becomes your asset: the more orthodox the proposition, the more it costs them to fight it. The asymmetry problem is real — especially in multi-defendant cases with two to four specialties — which is why the questions are organized as funnels rather than as debates.

What are the biggest traps when deposing a family medicine expert witness?

The classic traps are letting "primary care can’t work up everything" answer a question about one persistent, repeatedly reported symptom, letting the expert defend each visit in isolation instead of confronting the documented pattern, and never probing whether phone and portal contacts are missing from the chart the expert relied on.
