It’s 11 PM the night before a deposition. You’re surrounded by banker’s boxes, sticky notes, and three different highlight colors. You’ve been at this for six hours and you’re still not confident you’ve covered everything.

Sound familiar? Deposition prep is one of the most time-intensive tasks in litigation — and one of the highest-stakes. Miss a key document, forget to ask about a critical timeline, and the whole case can shift. AI won’t take the deposition for you, but it can cut your prep time dramatically while making sure you don’t miss anything.

AI won’t take the deposition for you, but it can cut your prep time in half.

Generating Deposition Questions

Start with the basics. Give AI the context and let it generate a first draft of questions:

“Generate 20 deposition questions for [deponent role] in a [case type] case. The key issues are [list issues]. Include a mix of: background questions, questions about specific events, questions about documents, and questions designed to lock in testimony. Organize by topic.”

This gives you a framework. You’ll add, remove, and reorder — but starting from 20 questions is faster than starting from zero.

Topic-Specific Question Sets

For more targeted prep, generate questions by topic:

“Generate 10 deposition questions about [specific topic — e.g., the defendant’s knowledge of the defect, the timeline of contract negotiations, the plaintiff’s medical treatment]. Focus on establishing facts that support [your theory of the case]. Include follow-up questions for likely evasive answers.”

Anticipating Testimony

This is where AI gets interesting. Ask it to role-play the deponent:

“You are [deponent role] in a [case type] case. The key facts are [brief summary]. I’m going to ask you deposition questions. Answer as this person would — including evasive or self-serving answers. Then, after each answer, suggest a follow-up question that pins down the testimony.”

This exercise helps you prepare for the actual deposition by anticipating how the witness will respond.

Document-Based Questions

If you have key documents, summarize them for AI and generate questions:

“I have an email from [person] to [person] dated [date] that says [summary]. Generate 5 deposition questions that use this email to establish [what you want to prove]. Include questions about who else saw the email, what actions were taken after it, and whether the statements in it are accurate.”

Creating the Deposition Outline

Once you have your questions, organize them:

“Organize these deposition questions into a logical outline. Group by topic. Start with background, then move to [chronological events / specific issues]. End with summary questions that lock in key testimony. Add time estimates for each section assuming a 7-hour deposition.”

Preparing the Deposition Notice

For the administrative side:

“Draft a Rule 30(b)(6) deposition notice for [entity] in [case name]. Topics of examination: [list topics]. Include standard document requests related to each topic. Follow [jurisdiction] rules for notice requirements.”

What AI Gets Wrong in Depo Prep

• Case-specific strategy — AI doesn’t know your judge, opposing counsel’s style, or the dynamics of your case
• Evidentiary rules — AI may suggest questions that are objectionable
• Witness psychology — reading a witness and adjusting in real-time is a human skill
• Privileged information — be careful what case details you share with AI tools

The Workflow

1. Day 1: Feed AI the case summary and key documents. Generate initial question sets by topic. (1 hour with AI vs 3-4 hours manual)
2. Day 2: Review and refine questions. Add case-specific follow-ups. Organize the outline. (2 hours)
3. Day 3: Practice with AI role-playing the deponent. Identify weak spots. (1 hour)

Total: 4 hours of prep. Without AI: 8-12 hours for a complex deposition.
