# Expert Witness Designation

Drafts a procedurally compliant expert designation that positions the expert's qualifications and opinions strategically while satisfying all disclosure requirements.

## Prerequisites

Gather before drafting:

- **Case info** — caption, case number, court, judge, designation deadline
- **Operative pleadings** — to map disputed issues the expert addresses
- **Expert details** — full name, address, phone, email, title, current CV, engagement letter, preliminary reports/findings
- **Prior testimony** — cases testified in during previous 4 years (FRCP 26(a)(2)(B)(v))
- **Prior designations** — from other matters for consistency
- **Compensation** — hourly rates by activity type, total paid to date

## Quick Start

1. Confirm governing rule (FRCP 26(a)(2) vs. state equivalent, e.g., CA CCP § 2034.260)
2. Identify each discrete opinion the expert will offer
3. Map every qualification to a specific case issue — no generic CV dumps
4. Draft opinion summaries with Daubert/Frye compliance built in
5. Attach or reference expert report per FRCP 26(a)(2)(B)

## Document Structure

### Front Matter

- Case caption matching court records
- Title: "[Party]'s Expert Witness Designation Pursuant to [Rule]"
- Governing rule citation
- Procedural context: timely designation, sequential/simultaneous exchange, rebuttal status

### Expert Identification

- Full name, address, phone, email
- Precise subspecialty tied to case issues
  - Good: "Board-certified forensic pathologist specializing in biomechanics of traumatic injury"
  - Bad: "Medical expert"
- Current professional role

### Qualifications Narrative

Present under FRE 702 framework:

- **Education** — degrees, institutions, honors, relevant fellowships/certifications
- **Experience** — positions relevant to disputed issues; quantify where possible ("performed over 500 of the procedure at issue")
- **Credentials** — licenses (jurisdiction, number, status), board certifications, professional memberships
- **Publications** — peer-reviewed articles on case-relevant topics, textbooks, treatises, editorial positions
- **Prior testimony (4-year)** — case name, court, jurisdiction, issues, depo/trial; note plaintiff vs. defendant balance; address prior Daubert exclusions proactively

### Opinion Summary

For each opinion:

1. **Conclusion** — definitive statement addressing a claim element or disputed fact
2. **Methodology** — analytical framework, testing protocols, standards applied
3. **Data reviewed** — specific documents, exhibits, depositions, test results (cite by exhibit number)
4. **Reasoning** — logical chain from data + methodology to conclusion
5. **Reliability** — Daubert/Frye factors: peer review, error rate, general acceptance
6. **Limitations** — assumptions, rejected alternatives, qualifications

Use technically accurate but jury-accessible language.

### Expert Report Checklist

- [ ] All data/information considered
- [ ] Supporting exhibits

- [ ] Prior testimony (4-year list)
- [ ] Compensation statement

### Compensation Disclosure

- Rates by activity (consultation, document review, report writing, deposition, trial)
- Total paid to date and estimated total through trial
- Non-standard arrangements (flat fees, retainers, expenses)

## Pitfalls

- **Generic qualifications** — every credential must connect to a specific case issue
- **Untraceable opinions** — each opinion must cite specific case evidence, not generalities
- **Daubert vulnerability** — build methodology defense into the designation itself; don't wait for the challenge
- **Bias exposure** — address repeat retention and publication positions proactively
- **Jurisdiction mismatch** — verify procedural requirements for the specific court and judge
- **Non-retained experts** — flag exceptions under FRCP 26(a)(2)(C) separately; different disclosure obligations apply
