Deposition Witness Preparation
description
Guides attorneys through deposition witness preparation using a two-session model with document review, practice examination, and day-of logistics. Covers party witnesses, fact witnesses, 30(b)(6) corporate representatives, and experts. Produces preparation memos, document review lists, topic summaries, and day-of checklists. Enforces ABA Opinion 508 ethical boundaries. Use when preparing any witness for deposition, scheduling prep sessions, or building witness preparation materials.
Structured framework for ethical, effective witness prep before depositions. Adapts to party witnesses, fact witnesses, 30(b)(6) corporate reps, and experts.
Prerequisites
Witness identity and type — party, fact, 30(b)(6), or expert
Deposition notice — date, time, location, noticed topics
Key documents — authored by, received by, or mentioning witness; likely exhibits
Set expectations: purpose is truthful, clear testimony — not scripted answers. Explain deposition mechanics (oath, attendees, court reporter, transcript use).
Address common concerns:
"What if I don't know?" → Say "I don't know"
"What if I don't remember?" → Say "I don't recall"
"What if I make a mistake?" → Correct via errata
"Will you help me?" → Attorney can object, but witness must answer
Ground Rules (20-30 min)
Listen fully — wait for complete question before answering
Clarify — "I don't understand" is always acceptable
Answer only what's asked — don't volunteer, explain, or justify
Tell the truth — evasion always makes it worse
"I don't know" vs. "I don't recall" — never-knew vs. can't-remember-now
Pause before answering — take your time
Flag problem questions — compound, false premise, characterization, absolutes
Document Review (60-90 min)
Review order:
Documents witness authored
Documents witness received
Documents mentioning witness
Key exhibits likely to be used
Witness's prior statements
For each document, capture:
Document
Witness Role
Key Points
Potential Issues
Author / Recipient / Mentioned
Red-flag documents (contradictions, bad phrasing, memory gaps): ask what witness recalls — do NOT suggest answers. Let witness formulate their own honest explanation.
Substantive Topic Review (60-90 min)
Per anticipated topic:
Explain why it matters to the case
Ask what witness knows (capture genuine recollection)
Review relevant documents
Identify uncertainty or difficulty areas
Focus vulnerable areas on: distinguishing knowledge vs. assumption, preparing for probing, ensuring document comprehension.
Close Session 1
Homework: documents to re-review, topics to reflect on
Spend extra time on vulnerable topics with multiple phrasings.
Objection Guidance (15-20 min)
Instruct witness: keep listening through objections, wait for objection to finish, then answer unless specifically told not to.
Instruction not to answer is rare — limited to: attorney-client privilege, work product (jurisdiction-dependent), court order violation, genuine harassment.
Day-Of Logistics (15-20 min)
Before: sleep, breakfast, professional dress. Arrive 15-30 min early. Bring government ID only — NO documents, notes, or files (discoverable).
During: no chatting with opposing counsel, no jokes on the record, phone out of room, don't discuss case in hallways or restrooms.
Day-Of Protocol
Pre-deposition (30 min before): final check-in, rule reminder, confirm break signals.
During: object briefly to preserve record ("Objection, form"). No speaking objections that coach witness. Request breaks for fatigue only — not to interrupt pending questions. Track admissions and problem areas.
Post-deposition debrief: brief emotional support, no detailed discussion until transcript review, explain errata process, remind witness not to discuss testimony with others.

Ethical Guardrails
ABA Opinion 508 — may explain law, review documents, practice questions, suggest clearer phrasing. May NOT suggest facts, tell witness what to say, conform testimony to other evidence, or discourage truthful testimony
ABA Model Rule 3.4 — fairness to opposing party and counsel
FRCP 30(c)-(d) — examination conduct and duration limits
All coaching refines expression of genuine recollection, never substance
For 30(b)(6) witnesses, align topic prep to deposition notice topics
