Your Workers’ Comp Deposition: What to Expect and How to Prepare

A workers’ comp deposition is a formal, recorded interview in which the insurance company’s lawyer asks you questions under oath while a court reporter takes down every word. Your own attorney sits with you the entire time, most depositions last a few hours, and in California the insurer generally has to pay your reasonable lost wages, travel costs, interpreter and your attorney’s fee for attending.

The deposition matters more than most injured workers realize. Your transcript follows your case to the medical evaluator, to settlement talks and, if needed, to trial. A careless answer about a prior injury or your daily activities can be used to cut your permanent disability rating or to question your credibility, and that can cost you thousands of dollars at settlement.

This guide explains who will be in the room, who pays for what, the questions the insurer’s lawyer almost always asks, how to handle prior injuries honestly, and a step-by-step plan to prepare.

What a workers’ comp deposition is, and why the insurer takes one

California Labor Code section 5710 allows the parties in a workers’ comp case to take depositions in the same general manner as in civil lawsuits. In practice, the deposition the insurer cares about most is yours: the “applicant’s deposition.” It usually happens after you have hired a lawyer and filed an Application for Adjudication of Claim with the Workers’ Compensation Appeals Board (WCAB).

The insurer’s lawyer (often called defense counsel) has three goals:

• Lock in your story of how the injury happened, so any later change looks suspicious.
• Find other causes for your condition, such as prior injuries, car accidents, sports or a second job, that could reduce what the insurer owes through apportionment.
• Measure you as a witness: are you clear, consistent and believable if the case goes to trial?

A deposition is not a hearing. There is no judge in the room, nobody decides your case that day, and you are not on trial. But your answers are given under penalty of perjury, so they carry the same weight as testimony in court.

Key fact

Who will be in the room

Depositions usually take place at a law office or court reporting office reasonably close to where you live, and many are now held by video. Expect a small group:

Person	Role	Can they talk to you?
You (the applicant)	Answer questions under oath	Yes, through answers only
Your attorney	Protects you, objects to improper questions, may ask follow-up questions	Yes, and you can ask for a break to talk privately
Defense attorney	Represents the employer and its insurer; asks most of the questions	Yes, but only through questions on the record
Court reporter	Swears you in and records every word	Neutral, takes no side
Interpreter (if needed)	Translates every question and answer word for word	Neutral, does not give advice

Your employer usually does not attend. Your supervisor, the claims adjuster and any nurse case manager are not normally part of an applicant’s deposition. If someone unexpected appears, tell your attorney before the deposition starts. (If a nurse case manager has been assigned to your claim, read our guide on nurse case managers in workers’ comp.)

If English is not your first language, ask for an interpreter. You have the right to testify in the language you are most comfortable in, and the defense pays for a qualified interpreter. Do not try to “get by” in English to save time; a misunderstood question can become a damaging answer.

Watch: injured at work in California

Our attorneys explain what your employer must do after a work injury, and what to do in the first 24 hours to protect your claim.

Who pays: your costs and your attorney’s fee

Because the insurer chooses to take your deposition, Labor Code section 5710 requires the employer or its insurer to cover the costs it creates for you. These generally include:

• Lost wages for the time you miss from work to attend.
• Reasonable travel expenses, such as mileage, parking, and meals or lodging if the deposition is far from home.
• Interpreter fees, if you need one.
• A reasonable attorney’s fee for your lawyer’s time preparing you and attending the deposition, paid by the defense and approved by the judge.

That last point surprises many people. The deposition fee is paid separately by the insurer; it does not come out of your benefits or your settlement. Keep a record of your mileage, parking receipts and hours missed, and give them to your attorney so the reimbursement request is complete.

💡 Example: Maria earns $28 an hour and misses a full 8-hour shift to attend her deposition. Under Labor Code 5710, the insurer should reimburse her lost wages of $224 (8 x $28), plus her mileage and parking. Her attorney’s deposition fee is billed to the insurer, so none of it reduces what Maria receives.

What the insurer’s lawyer will ask

Every deposition is different, but the topics are predictable. Expect questions about:

• Your background: education, where you have lived, and every job you have held, often going back 10 years or more.
• Your job duties: what a normal shift looks like, how much you lift, how often you bend, kneel, type or drive.
• How the injury happened: the date, time, place, what you were doing, who saw it, and who you told.
• Reporting: when you reported the injury and to whom, and when you received a claim form.
• Prior injuries and conditions: earlier work injuries, car accidents, sports injuries and any treatment for the same body part.
• Medical treatment: every doctor you have seen, what they told you, and what medications or therapy you have received.
• Your current symptoms and limits: what you can and cannot do at work, at home and in your free time.
• Other activities: second jobs, hobbies, sports, social media and household chores.

Answer only what is asked. If the lawyer asks whether you lift weights, the answer is “yes” or “no,” followed by a short, accurate explanation if needed. You do not need to fill silences.

Prior injuries: why honesty protects your case

This is where most damage happens in depositions, and it is almost always avoidable. Insurers usually have access to claims databases, prior medical records and earlier workers’ comp files before your deposition starts. The defense attorney often already knows the answer to the question.

Under California’s apportionment rules (Labor Code sections 4663 and 4664), a doctor may decide that part of your permanent disability is caused by something other than your work injury, which can reduce the award. That is a real issue, but it is one your attorney can address with medical evidence. What your attorney cannot fix is a denial that later turns out to be false. A hidden prior back injury turns a fair apportionment fight into a credibility problem, and making a knowingly false or fraudulent material statement to obtain benefits is a crime under Labor Code section 1871.4.

So disclose prior injuries, accidents and treatment to your own attorney before the deposition, then answer honestly when asked. “I hurt my back in 2019, had six weeks of physical therapy, and was fine until this injury” is a strong, believable answer. If you truly don’t remember a detail, say so; “I don’t remember” is an acceptable answer, while a guess is not.

How to prepare, step by step

1. Meet with your attorney before the deposition, in person or by video. Go over the injury, your work history and your medical history in detail.
2. Review your own timeline. Write down your hire date, the injury date, when you reported it, and the doctors you have seen. Bring nothing into the deposition unless your attorney tells you to.
3. List prior injuries and claims, including car accidents and old workers’ comp cases, and share the list with your attorney.
4. Think about your daily limits. Be ready to describe your good days and bad days with concrete examples, such as how long you can stand or what you can no longer lift.
5. Check your social media. Do not delete posts (that can look like hiding evidence), but stop posting about physical activities, and ask your attorney about privacy settings.
6. Request an interpreter early if you need one, so it is arranged before the date.
7. Plan the day. Get sleep, eat beforehand, bring any medication you need, and leave time for traffic or login problems.
8. Track your costs: mileage, parking and missed hours, for reimbursement under Labor Code 5710.

Rules for answering questions

• ✅ Tell the truth. Inconsistencies hurt more than unfavorable facts.
• ✅ Listen to the whole question and pause before answering, so your attorney has time to object.
• ✅ Answer only what was asked. Don’t volunteer extra stories or explanations.
• ✅ Don’t guess or estimate unless asked to, and say when you are estimating.
• ✅ Don’t minimize or exaggerate. Describe your pain and limits accurately.
• ✅ Ask for clarification if a question is confusing, compound or uses words you don’t understand.
• ✅ Take breaks when you need them, just not while a question is waiting for an answer.

Stay calm if the defense attorney is friendly, or if they are not. Their tone is a technique either way. Your job is the same: clear, short, truthful answers.

After the deposition: the transcript and how it is used

The court reporter prepares a written transcript. In most cases you and your attorney receive a copy and get a set period to read it and correct transcription errors before signing. Read it carefully; a wrong date or a “can” that should be “can’t” matters. Changes to the substance of your answers can be commented on later, so accuracy on the day is what counts.

The transcript is then used throughout the case. It is commonly sent to the Qualified Medical Evaluator (QME) or Agreed Medical Evaluator (AME), whose report drives your permanent disability rating. It shapes how the insurer values your case at settlement and can be used at a mandatory settlement conference or trial before the WCAB.

Be aware that insurers sometimes hire investigators to film injured workers in public around the time of a deposition or medical evaluation. If what you say matches what you do, surveillance cannot hurt you.

Your deposition is one part of a bigger claim

A deposition is often the first time an injured worker sees how hard the insurer intends to fight. It is also a good moment to check the rest of your claim. Are your temporary disability payments correct and on time? Has treatment been delayed or denied? Is the insurer questioning whether the injury happened at work at all? Each of these problems has its own remedy, and an experienced attorney will raise them as the case moves toward a QME evaluation and settlement.

If you were fired, demoted or treated differently after reporting your injury, you may also have separate claims under Labor Code section 132a or California’s Fair Employment and Housing Act. Those claims are handled differently from the workers’ comp case and have their own deadlines.

Frequently asked questions

Do I have to attend my workers’ comp deposition?

Generally, yes. If you are properly noticed and refuse to attend without a good reason, the insurer can ask the judge to order you to appear and may seek to suspend or delay benefits. If the date doesn’t work, tell your attorney right away so it can be rescheduled.

How long does a workers’ comp deposition last?

Most applicant depositions take two to four hours, though complex cases with many prior injuries or body parts can take longer. Interpreted depositions take more time because every question and answer is translated.

Can I bring a family member?

Usually a family member can wait outside but should not be in the room while you testify, unless your attorney arranges otherwise. Ask your attorney beforehand.

Will I be paid for missing work to attend?

Yes. Labor Code section 5710 requires the defense to reimburse reasonable lost wages and travel expenses for attending your deposition, and to pay your attorney’s deposition fee.

Can I settle my case without a deposition?

Yes. Some cases settle before a deposition is ever taken. Whether settling early makes sense depends on your medical evidence and the offer; see should you accept a workers’ comp settlement offer.
