Hostile opposing counsel, under oath. It locks you into specifics, impeaches imprecision against your own case file, asks the same question three ways when you dodge, and builds chains of harmless admissions into conclusions you didn't see coming.
A deposition is sworn testimony taken outside the courtroom, before trial. In a US civil case it is part of discovery: the opposing attorney questions you under oath, a court reporter takes down every word, and the session is often video-recorded. There is no judge in the room and no jury watching. That makes it feel informal. It isn’t.
Everything you say becomes a transcript, and that transcript follows you. It can be read back at trial, quoted in motions, and used to impeach you if your later testimony drifts. Most depositions are not won by the witness. They are lost by the witness — one volunteered sentence, one guess, one “always” at a time. Mock deposition practice exists to make those mistakes in a room where they cost nothing.
Below is what actually happens, the traps opposing counsel sets, and how to get ready. For the twelve rules of testifying well, read the witness’s ground rules — this page is the procedure and the practice.
You are sworn in by the court reporter. Your attorney sits beside you; opposing counsel sits across. Other parties or their lawyers may attend. Exhibits are marked and handed to you. In federal civil cases a deposition is limited to one day of seven hours of questioning unless the parties agree or the court orders otherwise, and state rules vary. Breaks are normal. Ask for them — but not while a question is pending.
Early questions feel like small talk — background, education, jobs, who you spoke to about the case. They are building a map. Later questions pin you to dates, names, amounts, and documents, then exhaust the subject: “Is there anything else?” “Anyone else?” The goal is a transcript with no room for you to add or change anything at trial.
Your attorney may object to the form of a question — compound, vague, assumes facts, calls for speculation. In most depositions the objection is noted for the record and you still answer, unless your attorney instructs you not to, typically to protect privileged communications. When your attorney starts speaking, stop. Then listen to the objection; it often tells you exactly what is wrong with the question.
“What did you do to prepare for today?” (careful: conversations with your lawyer are generally privileged; documents you reviewed may not be). “So it’s fair to say…” (a summary with one word changed). “You would agree that…” (a conclusion dressed as a fact). “Would it surprise you to learn…” (an invitation to speculate). “Walk me through that day.” (an open door for you to volunteer). Each one rewards a short, accurate answer and punishes a helpful one.
Skilled counsel rarely asks the damaging question directly. They collect small yeses — you received the email, you read your email daily, you were in the office that week — and let the conclusion assemble itself. You cannot prevent the chain, but you can refuse any link that isn’t precisely true: “I usually read my email. I don’t recall reading that one.”
You will be handed emails, contracts, reports, and your own prior statements. Take the time to read the entire document before answering, not just the paragraph counsel points to. If you don’t recognize it, say so. If you didn’t write it, don’t speculate about what the author meant.
Review the key documents with your attorney. Build a clean timeline of what you actually know versus what you have since learned or assumed. Then practice answering out loud, under pressure, until short answers feel natural and silence stops feeling like an emergency. A mock deposition with a real attorney is the gold standard; every extra rep you run on your own makes that session sharper.
Load your material — the complaint, your declaration, the emails, a scanned exhibit; OCR handles image-only PDFs. Tell the AI your role and context: “I am the defendant’s operations manager; question me about the March shipment.” Every room states both chairs before you start. Then press the mic. Opposing counsel opens, and the session runs entirely by voice.
It commits you to dates, names, and amounts pulled from your material, asks the same question three ways when you dodge, moves to strike non-responsive answers, and impeaches you the moment your answers start contradicting each other. Go silent and it prompts you once, firmly; stay silent and your composure scoring notices. Strong answers buy you harder questions.
Use the Pressure Intelligence box to name the question you are dreading — the examiner holds it in confidence and works toward it the way real counsel would. Every answer is scored on eight skills, with sentence-level deception-risk flags that show where your language reads as hedged or distanced. They are a training indicator, not a lie detector. And nothing is kept: no recordings, no transcripts, and the material you load is never written to our database. How to get the most out of a session · Trust & Security
Meet with your attorney, review the key documents, and build a timeline that separates what you personally know from what you assume or learned later. Then practice answering out loud: listen to the whole question, pause, answer only what was asked, never guess, and correct any summary of your testimony that is not accurate.
Expect background questions about your education, work history, and prior lawsuits, then detailed questions about the events in the case, the documents you wrote or received, the people you spoke with, and what you did to prepare. Opposing counsel will also ask catch-all questions such as whether there is anything else or anyone else, to close off the subject.
Yes. Knowing the rules is easy; keeping them for hours under a skilled questioner is not. A mock deposition shows you where you volunteer, guess, or lose composure before it lands in a sworn transcript. A session with your own attorney is the best version, and extra solo reps make that session more productive.
Yes. The 3rd Degree Deposition room is a live voice AI that plays hostile opposing counsel, questions you on the material you load, and scores your answers. It is a preparation tool only and does not provide legal advice, so use it alongside preparation with your attorney, not instead of it.
