Expert Witness Deposition
Builds a motion-ready expert deposition record or defense-prep plan targeting Daubert/Frye admissibility. Covers qualification limits, methodology attacks, bias/compensation exposure, and opinion lock-in.
Prerequisites
- Venue admissibility standard (Daubert, Frye, or state hybrid) and local expert disclosure rules
- Rule 26(a)(2) expert report(s) and disclosure materials
- Expert CV, publications, and prior testimony list
- Case facts and key documents (reviewed and not reviewed by expert)
- Alternative theories, critiques, or rebuttal materials
Quick Start
Begin every expert deposition task with an intake snapshot:
| Field | Detail |
|---|
| Jurisdiction | Federal/State, Daubert/Frye, local rules |
| Expert | Name, field, retention side, role |
| Opinions | Enumerated list from report |
| Methodology | Methods, standards, tools, testing |
| Materials | Documents reviewed, gaps, assumed facts |
| Bias | Compensation, retention history, firm ties |
Then choose the appropriate workflow: Taking (Deliverable A) or Defending (Deliverable B).
