Expert witness vetting

Vet the expert
before you put them on the stand.

An expert witness with an undisclosed conflict of interest, contested credentials, or a pattern of partisan testimony can sink your case. Tracelight runs the same diligence on opposing experts you'd want done on your own — sanctions, prior testimony record, corporate ties, social-media history, breach exposure — in under 5 minutes per expert.

What this fixes.

PAIN 1

Credentials disputes surface in deposition, not before.

The 'expert' whose CV claims a board certification they don't actually hold is a known phenomenon. Verifying credentials manually means calling registries one at a time. OSINT scans the public side of the same data instantly.

PAIN 2

Conflict-of-interest searches don't scale across multi-defendant cases.

Vetting one expert per side is fine. Vetting a witness pool of 8 across a multi-defendant litigation is a week of paralegal time. Tracelight runs the cohort in parallel.

PAIN 3

Prior-testimony patterns matter for impeachment.

If the expert has testified 47 times for the same insurance carrier, that's a Daubert challenge waiting to happen. The data is in PACER + state court systems — but only if you actually pull it.

What gets checked

8+ data sources running in parallel.

PACER + state court records (US)

Companies House + OpenCorporates for board / advisory roles

Sanctions + politically-exposed-persons lists

Adverse media + retraction database scan

Social-media activity (declarations, op-eds, advocacy)

Patent + publication record (Google Scholar / USPTO cross-check)

Professional registry verification (state bar, medical board, IEEE, etc.)

Breach exposure — credential-theft signals on the expert's email

What you get

The report that lands on your desk.

1
Expert profile with credential-verification status per claimed certification
2
Prior-testimony record (cases, parties retained by, outcomes where public)
3
Conflict-of-interest section with corporate + advisory roles
4
Reputation timeline including any retractions, disputes, or controversies
5
Cross-case intelligence: has this expert been associated with any of your other open matters

Common questions.

Can I use this for opposing experts as well as my own?+

Yes — that's the higher-value use case. Vetting the opposing expert before deposition gives you impeachment ammunition (prior inconsistent testimony, undisclosed financial relationships, credential gaps). Vet your own to know what's coming back at you in cross-examination.

Does this cover non-US experts?+

Partially. US-source data (PACER, USPTO, state registries) is the most complete. UK + EU data via Companies House and OpenCorporates is reasonable. Non-Western jurisdictions are spotty — we add sources as customer demand justifies.

Is the report admissible to support an impeachment motion?+

The underlying evidence is admissible insofar as it's sourced from public records. The Tracelight report itself is a workproduct summary; you'll typically introduce the underlying source documents (court filings, registry records) directly. The audit trail makes that re-introduction easy.
