To prepare for a deposition as a plaintiff, review your complaint, interrogatory answers, and medical records for accuracy, dress business casual, and follow two rules above all else: never guess and never lie. A deposition is sworn testimony given under oath, months before trial, so calm, honest, listen-then-answer habits protect your case far more than a rehearsed speech.
What Is a Deposition, and What Is the Defense Trying to Get From It?
A deposition is a set of questions a defense attorney asks you under oath, months before trial, with a court reporter typing every word and no judge in the room, usually at a law office rather than a courthouse. Either side can take a party’s deposition without a judge’s advance permission in the ordinary case, and the questions only need to be relevant and “reasonably calculated to lead to the discovery of admissible evidence,” not necessarily admissible themselves.
The defense already has your medical records, the accident report, and your interrogatory answers before you sit down. They still want your deposition because live testimony does three things paperwork cannot: it locks in your account before trial, lets them size you up as a witness, and makes an inconvenient detail far harder to gloss over than it would be on paper. Expect questions to range beyond the crash itself: why a seemingly off-topic question can still be fair game comes up often, and how something in your past becomes part of your case depends on whether it’s genuinely relevant, not just embarrassing to admit.
The usual setup is a conference table, you seated next to your own attorney, the defense attorney across from you. The person or company you’re suing can legally attend, though most skip it, and a friendly rapport between the two lawyers doesn’t mean anything’s being given away. Whether you can sit in on someone else’s deposition works a little differently, so don’t read anything into who does or doesn’t show up at yours.
Two Ground Rules Before You Ever Answer a Question
First: your attorney cannot answer for you, even a harmless-feeling question. If you think a question touches attorney-client privilege, you can pause and talk with your attorney about that issue itself, but the deposition tests your own knowledge and memory, not your lawyer’s.
Second: this is not your chance to tell your side of the story. Most plaintiffs assume a deposition is where they get to explain everything, but it’s really the defense’s chance to gather information, not yours to give a speech. Answer only what’s asked; if the defense never raises something you think matters, save it for your own attorney’s questions at trial instead.
What to Wear and What to Review Beforehand
Dress business casual and comfortable. A suit isn’t necessary; look professional enough that a jury would take you seriously if the transcript were ever read aloud in court.
Before the day itself, review, don’t memorize, your complaint, interrogatory answers, and the accident report if one exists. You’re checking for errors that need correcting, not cramming for a test. Flag anything wrong to your attorney right away, and expect your attorney to meet with you beforehand about anything specific to your case, such as a prior injury to the same body part.
The Defense Attorney’s Attitude Doesn’t Change Your Strategy
Expect friendliness more often than hostility, since a pleasant defense attorney is using the most effective tactic there is: people volunteer more when a conversation feels comfortable. Keep two things in mind once the questions start: this person is not your friend, and this is not a conversation. The second point matters most, since a chat that starts feeling relaxed is exactly when people start offering details nobody asked for.
An attorney who instead seems to be needling you calls for the opposite response: patience. Avoid sarcasm, and don’t let frustration show; jurors respond to a sympathetic witness, not an irritated one. If you think you’re being deliberately provoked, ask for a break and talk to your attorney first.
How Long a Deposition Actually Takes
Plan on at least an hour, with two to four hours typical; a complicated medical history tends to push it longer. Oklahoma law caps most depositions at six hours in a single day absent a court order or agreement otherwise (12 O.S. Section 3230), though few plaintiff depositions come near that limit. How long yours runs often depends more on the defense attorney’s own style than on your case itself.
The Two Mistakes That Cost You the Most: Lying and Guessing
Lying under oath is the single worst thing you can do in a deposition. Lawsuits often run for years, and it’s extraordinarily difficult to fake a limp, a lifting restriction, or constant pain without a surveillance camera, a neighbor, or your own social media eventually catching the inconsistency. Getting caught can mean dismissal and owing the other side’s costs. There’s a real difference between lying and simply being wrong: saying the crash happened on a Saturday when it was actually a Sunday is an honest, correctable mistake, not testimony given falsely under oath.
Guessing is the second-worst thing you can do. When a question puts you on the spot, “I don’t know” or “I don’t remember” is a complete, honest answer, and it protects your credibility better than a confident-sounding guess that turns out wrong. Saying the other driver’s car was black when it was actually yellow calls your whole account into question. If you’re genuinely estimating, say so out loud, such as “I’m not certain, but I’d estimate five seconds,” rather than stating a guess as fact.
Handling Mistakes in Your Own Records
Medical records and accident reports contain errors more often than people expect, anything from a wrong date to a note claiming you weren’t wearing a seatbelt when you were. Don’t let an inaccurate record intimidate you. When a defense attorney holds one up and asks you to explain someone else’s mistake, restate what you actually said or did rather than guessing why a doctor or officer wrote what they wrote. Errors also tend to repeat, since later providers often copy facts forward from an earlier visit.
Videotaped Depositions and the “Silence” Trick
Being told your deposition will be recorded on video isn’t a red flag by itself. Some firms record every plaintiff’s deposition as standard practice, and a camera tends to keep a difficult defense attorney more polite, not less.
Watch for the “silence” trick: after you answer, an attorney may pause ten or fifteen seconds hoping the quiet pressures you into adding more. Let it sit; it’s a tactic, not a slip on your part, and a transcript won’t show that any pause happened at all. A deposition also isn’t an endurance test: reasonable breaks, roughly one an hour, are normal, whether you need one for discomfort from an injury or just a minute to reset.
Always Read and Sign Your Deposition Transcript
At the end of the session, you’ll be asked whether you want to read and sign the finished transcript or waive that right. Always choose to read and sign. Oklahoma procedure gives you thirty days after the transcript becomes available to note any changes in form or substance on a separate errata sheet (12 O.S. Section 3230), and this isn’t limited to the court reporter’s typos; you can correct any answer you later realize was wrong or incomplete. Catching a mistake now beats surfacing it at trial, though a major change, like adding a never-mentioned injury, may prompt a second, narrower deposition on that topic alone.
A car accident case follows its own discovery-to-settlement timeline once a lawsuit is filed, and the condensed five-point version of this advice is worth a second look the morning of your deposition. Clayton Hasbrook has practiced Oklahoma injury law since 2008, and the attorney who sits beside you at that table, not across from it, can walk you through what your own case’s deposition will involve. Talk with our office before your deposition is scheduled, or call 405-605-2426.
