What Is a Deposition? A Personal Injury Plaintiff’s Guide to What to Expect

You filed a personal injury claim. You’re working with an attorney. And now the other side’s lawyer wants to take your deposition. For most people, this is the most intimidating part of the litigation process — and also the least understood.

A deposition doesn’t have to be something you dread. When you know what it is, how it works, and what the other side is actually trying to accomplish, you can walk in prepared. Here’s everything a personal injury plaintiff needs to know.

What Is a Deposition?

A deposition is sworn, out-of-court testimony taken during the discovery phase of a lawsuit. You testify verbally in response to questions from the opposing attorney, under oath, and a court reporter transcribes everything you say. The transcript can be used as evidence at trial — either to support your case or to challenge your credibility if your trial testimony differs from what you said in the deposition.

Depositions typically happen after a lawsuit has been filed, once both sides have exchanged initial documents and discovery materials. They’re a fact-finding tool — the other side’s attorney is trying to understand your version of events, identify inconsistencies, and evaluate the strength of your case before trial.

Who Is at a Deposition?

A typical deposition in a California personal injury case includes:

• You — the witness being deposed
• Your attorney — present to make objections and protect your interests
• The opposing attorney — asking the questions
• A court reporter — transcribing every word spoken
• Sometimes a videographer, if the deposition is being recorded on video
• Sometimes the insurance company representative or other parties to the lawsuit, depending on the case

The setting is usually a conference room — at a law office, a court reporter’s office, or sometimes by video. It’s formal in that you’re under oath and the record matters, but it’s not a courtroom.

What Will They Ask You?

The opposing attorney’s questions will cover several areas. Understanding these in advance helps you prepare:

Your Personal Background

Expect questions about your name, address, employment history, education, and prior injuries or medical conditions. They’re establishing baseline information and looking for prior medical history that might be relevant to your current injuries.

The Accident Itself

A detailed walkthrough of exactly what happened: where you were going, what you were doing, what you saw before the crash, what you remember about impact, and what happened immediately afterward. They’ll ask about your physical condition at the time (any alcohol or medication, how much sleep you’d had, whether you were using your phone).

Your Injuries

Every injury you’ve reported, every doctor you’ve seen, every treatment you’ve received. They’ll ask about your current symptoms, your limitations, and how your injuries have affected your daily life, work, and relationships. They’re looking for inconsistencies between what’s in your medical records, what you’ve told your doctors, and what you say now.

Your Prior Medical History

Any prior accidents, injuries, surgeries, or medical conditions — especially anything involving the same body parts you injured in this accident. Prior medical history is often the most important area for the opposing side. If you had a prior back injury and now claim a new back injury from the accident, they’ll dig into this extensively.

Your Damages

Lost wages, out-of-pocket expenses, your ability to work, activities you can no longer do, the impact on your relationships. They’re evaluating the credibility of your damages claims.

Your Rights During a Deposition

You are under oath to tell the truth, but you also have important rights:

• You can ask for clarification. If you don’t understand a question, say so. “I don’t understand what you’re asking” is a complete answer. Answer only once you understand.
• You can take time to think. You don’t have to answer immediately. A pause before responding is normal.
• You can say you don’t know or don’t remember. These are accurate and appropriate answers when true. Don’t guess — guessing creates a record of a specific answer you’re not sure about.
• Your attorney can object. Your attorney will interject with objections when appropriate. If your attorney objects, wait — they’ll tell you whether to answer or hold off.
• You can ask for a break. Depositions aren’t marathons. If you need a moment, ask for one.

The Most Important Deposition Rules

Your attorney will go over these with you before the deposition. But here are the core principles:

Tell the truth — completely and consistently

Your deposition testimony is sworn and recorded. Any inconsistency between what you say now and what you say at trial will be used against you. The opposing attorney will have the transcript in front of them during trial. Tell the same true story you’ll tell at trial — because it’s the same story.

Answer only the question asked

This is where most people get into trouble. They answer the question and then keep talking, adding context, clarifying, explaining. Don’t. Answer the question. Stop. Wait for the next question. Volunteering information gives the other side material they weren’t going to get — and your attorney can present the full context on your behalf at the right moment.

Don’t guess

“I don’t know” and “I don’t remember” are valid answers. If you’re not certain about a speed, a distance, a time, or a specific detail — say so. “I’m not certain, but it seemed like about…” opens a door to attacking your estimate. “I don’t know exactly” does not.

Correct mistakes immediately

If you realize mid-deposition that something you said earlier was wrong, correct it immediately. “Actually, I need to go back — I said X but I meant Y.” Corrections made during the deposition are cleaner than inconsistencies discovered at trial.

Preparing for Your Deposition

Your attorney should meet with you before the deposition to review your case and go through the likely questions. Here’s how to prepare on your end:

• Review your medical records. Know your treatment timeline, your doctors’ names, and the progression of your recovery. The other side will have these records and may ask detailed questions.
• Review your accident description. Know the facts of what happened and have a consistent, clear narrative. You shouldn’t memorize a script — you should know your own story.
• Think about your prior medical history. Be ready to discuss any prior injuries, especially to the same body parts. Consistency between your medical history and your deposition testimony matters.
• Dress professionally. If the deposition is being videotaped, it may be used at trial. First impressions count even in a conference room.
• Get a good night’s sleep. Fatigue makes you less precise and more likely to volunteer extra information.

What Happens After the Deposition?

The court reporter produces a written transcript. You typically have the right to review and correct the transcript for factual errors (not to change substantive answers — corrections are for transcription mistakes). After review, you sign the transcript under penalty of perjury.

The deposition transcript becomes part of the case record. It can be used at trial to question you if your answers differ from your deposition testimony. It’s also used by both sides to evaluate the strength of the case and inform settlement discussions.

In many cases, the deposition is followed by intensified settlement negotiations — once both sides have a complete picture of the evidence, cases often resolve.

Frequently Asked Questions About Depositions

What is a deposition in a personal injury case?

A deposition is sworn out-of-court testimony taken during the discovery phase of a lawsuit. A court reporter transcribes everything. The opposing attorney asks questions about the accident, your injuries, your medical history, and your damages. The transcript is admissible at trial.

How long does a deposition last?

Most personal injury depositions last between one and four hours, depending on the complexity of the case. California limits most depositions to seven hours of testimony in a single day without a court order for extension. Your attorney can ask for breaks at any time.

Do I have to answer every question at a deposition?

You must answer lawful questions asked in good faith. Your attorney can object to questions that are improper — irrelevant, privileged, harassing, or calling for speculation. If your attorney instructs you not to answer, follow that instruction. Otherwise, you’re required to respond to questions truthfully.

Can a deposition hurt my case?

A poorly handled deposition can. Inconsistencies between deposition testimony and other evidence, over-explaining, or guessing on details you’re not sure about can all create problems. Proper preparation with your attorney minimizes these risks significantly.

What should I wear to a deposition?

Business casual or professional attire. If the deposition is being recorded on video, that recording may be shown to a jury. Dress as you would for a job interview or a court appearance. Avoid casual clothes, hats, or anything that might create a negative impression.

What happens if I say something wrong in my deposition?

Correct it immediately — say “I need to go back and correct something I said earlier.” You also have the right to review the written transcript after the deposition and correct any transcription errors before signing. Substantive changes to your testimony after the fact are more difficult but can sometimes be addressed through supplemental declarations or at trial with explanation.
