The opposing expert's CV arrives with the FRE 26(a)(2)(B) disclosure. Most plaintiff attorneys glance at it, note the credentials, and move on. The well-prepared attorney spends 30 minutes vetting it — and finds the vulnerabilities that drive Daubert motions, motions in limine, and devastating cross-examination.

Here's the 30-minute CV vetting checklist, with the 7 red flags that consistently appear on weak experts.

The 30-minute framework

Allocate the time as follows:

StepTimeWhat you're looking for
Board certification verification5 minSubspecialty mismatch, expired certification, recertification gap
Hospital privileges audit5 minPrivileges that don't match claimed expertise, gaps, restrictions
State medical-board record5 minDisciplinary action, license restrictions, malpractice history
Publication record review10 minProductivity, content, contradictions to anticipated case opinions
Prior testimony cross-check5 minExpert work volume, plaintiff/defense ratio, repeat clients

1. Board certification verification (5 min)

Use the American Board of Medical Specialties certification verification tool at certificationmatters.org. Enter the witness's name; you'll see every active and expired certification.

What to look for:

Red flag #1: Witness offers opinions in a specialty different from their board certification. Example: a board-certified internist offering opinions on neurosurgical technique. This is a Daubert qualifications challenge.
Red flag #2: Witness's primary board certification has expired. ABMS recertification cycles vary by board (typically 7-10 years). An expired certification is not necessarily disqualifying but signals diminished engagement with current practice — and is a foundational deposition question.

Cross-check against the witness's CV. CV claims of certification not appearing on the ABMS database are a major credibility problem.

2. Hospital privileges audit (5 min)

Hospital privileges are state-licensable and publicly verifiable through individual hospital websites. They establish that the witness is currently practicing — and at what level.

What to verify:

Red flag #3: Witness has no active hospital privileges in the specialty they're testifying about. This often indicates a transition to pure expert-witness work, which is foundational to a Daubert challenge on currency.

Cross-reference against the National Practitioner Data Bank (querulously available; may require subpoena) and state medical-board licensing records.

3. State medical-board record (5 min)

Every state board publishes licensing records and disciplinary actions. The Federation of State Medical Boards directory at fsmb.org aggregates the lookups.

What to find:

Red flag #4: Witness has any disciplinary action in the relevant time period. Even minor disciplinary findings (failure to maintain CME, billing irregularities) damage credibility and create cross-exam material.

Many states include public detail on the basis of any complaint that resulted in formal action. Pull the underlying records when available.

4. Publication record review (10 min)

This is where 30-minute vetting separates from cursory review. Search the witness's name in PubMed (pubmed.ncbi.nlm.nih.gov) using all common variations: full first name, first initial, middle initial.

What to assess:

Red flag #5: No publications in the witness's claimed specialty within the last 10 years. Combined with no current hospital privileges, this is a textbook Daubert qualifications challenge.
Red flag #6: Witness's own published work contradicts their anticipated case opinions. This is the single highest-leverage finding any 30-minute vetting can produce.

5. Prior testimony cross-check (5 min)

The FRE 26(a)(2)(B)(v) disclosure lists prior cases. Beyond that, search the witness's name in:

For deeper guidance: how to find prior testimony of a medical expert witness.

Red flag #7: Witness testifies overwhelmingly for one side (>80%). Bias is generally a credibility issue, not Daubert — but extreme one-sidedness combined with high testimony volume can support an argument that the methodology is "results-driven" rather than principled.

The vetting output

End the 30-minute vetting session by writing a one-page memo answering 5 questions:

  1. Is the witness qualified, period? (Disqualifying findings: no relevant certification, no current practice, expired license, disciplinary revocation.)
  2. Are there limited-scope qualifications gaps? (Witness qualified generally but not for specific opinions.)
  3. Are there contradictory prior positions? (Publications, prior testimony, board statements.)
  4. Are there bias indicators? (Testimony volume, plaintiff/defense ratio, repeat clients.)
  5. Are there motion-quality findings? (Daubert? Motion in limine? Cross-exam ammunition?)

The memo becomes the foundation for: deposition outline, Daubert motion (if warranted), motion-in-limine drafting, and cross-examination strategy at trial.

The pre-deposition extension

30-minute CV vetting is the floor, not the ceiling. Cases with high stakes deserve extended vetting: depositions of the witness's prior cases, conference-talk video review, social media analysis (yes, really — many doctors post clinical opinions on Twitter/X that contradict their case testimony), and grand-rounds talk recordings.

The economic test: vetting time should scale with case value. A $50K case warrants the 30-minute floor. A $5M case warrants 5+ hours of vetting per opposing expert.
