TL;DR
A deposition is a formal session where witnesses answer questions under oath outside of court. The testimony is recorded and can be used at trial. Depositions happen during discovery, after a lawsuit is filed, and typically before any settlement is reached.
This guide explains what a deposition is, why it happens, what to expect in the room, what questions get asked, common mistakes to avoid, what happens after, and how deposition testimony influences the settlement process in personal injury cases.
Most personal injury clients have never been through a deposition. The process is more structured than most people expect. Understanding what happens at each stage removes the uncertainty and helps clients give their best testimony when it matters.
A deposition is sworn, recorded testimony taken outside the courtroom during discovery. Both sides use it to lock in testimony and assess how witnesses will perform at trial. Per Nolo, most personal injury depositions last between one and four hours, though complex cases with extensive medical histories can run longer.
This guide is written for personal injury clients preparing for their deposition. It covers every stage of the process in plain language. Attorneys frequently share this type of guide with clients before their deposition date as a preparation resource.
What Is a Deposition?
A deposition is a formal proceeding where a witness answers questions under oath and a court reporter transcribes every word. In a personal injury case, depositions typically occur after a lawsuit is filed and before the case goes to trial or settles.
The testimony in a deposition personal injury case carries the same legal weight as court testimony. If your account contradicts what you say at trial, the opposing attorney will use that inconsistency to challenge your credibility before the jury.
Depositions are not held in a courtroom. They typically take place in a conference room at one of the attorneys’ offices or in a neutral location. The setting is less formal than a courtroom, but the oath and the legal consequences of your testimony are identical.
Why Depositions Happen in Personal Injury Cases
Both sides have the right to gather information before trial. Depositions serve several distinct purposes that benefit both the plaintiff and the defense.
- To lock in testimony: once you give sworn testimony in a deposition, that record exists. If your account changes later, the discrepancy can be used against you. That is why consistency between the deposition and any prior statements matters.
- To assess witness credibility: attorneys evaluate how confident, clear, and consistent a witness is. A deposition is often the first time the defense attorney sees the plaintiff in person and forms their assessment of how that person will perform at trial.
- To support settlement negotiations: strong, consistent testimony accelerates settlement. Weak or inconsistent testimony gives the insurer grounds to lower the offer.
- To preserve testimony for trial: if a witness is unavailable at trial due to health, relocation, or other reasons, their deposition transcript can be read into the record or the video played for the jury.
Before the Deposition: How to Prepare
Knowing how to prepare for a deposition is the most important factor in how well it goes. Most attorneys schedule at least one preparation session with their client before the deposition date.
- Meet with your attorney in advance. Go through the case facts, review any prior statements you have made, and understand the type of questions the defense attorney is likely to ask. Do not wait until the day before.
- Review your medical records and treatment history. Know the providers you have seen, the treatments you have received, and the current status of your injuries. Inconsistencies between your testimony and the medical record create unnecessary problems.
- Understand the ground rules. Your attorney will explain what you can and cannot do during the deposition: how to handle questions you do not understand, when it is appropriate to say you do not know, and how to handle objections.
What Happens During a Deposition
Who Is in the Room
The deposition process typically involves the following people in the room:
- The witness: the person being deposed, usually the plaintiff in a PI case. Expert witnesses, treating physicians, and fact witnesses from the scene may also be deposed separately.
- The court reporter: a certified professional who transcribes every word spoken in the room in real time. The transcript they produce is the official record of the proceeding.
- Your attorney: present throughout the deposition to protect your rights, raise objections when appropriate, and provide guidance during breaks.
- The opposing attorney: typically represents the defendant or the insurance company. They conduct the questioning during the plaintiff’s deposition.
- A videographer (sometimes): many depositions are now video recorded in addition to being transcribed, particularly for witnesses who may not be available at trial.
Types of Questions You Will Be Asked
Deposition questions in a personal injury case generally fall into several categories. Knowing what to expect helps you answer more clearly and confidently.
- Background questions: your name, address, employment history, education, and prior legal history. These establish your identity and credibility as a witness.
- Incident questions: a detailed account of how the accident or incident occurred, what you observed before and immediately after, and who was present. Expect to walk through the timeline multiple times.
- Injury questions: the nature and location of your injuries, how they were first treated, whether you had any pre-existing conditions in the same area, and how your symptoms have changed over time.
- Medical treatment questions: every provider you have seen since the incident, the frequency of treatment, what each provider told you, and whether you followed all recommended care.
- Impact questions: how the injuries have affected your work, daily activities, relationships, sleep, and overall quality of life. These questions support or undermine the non-economic damages claim.
- Prior history questions: prior accidents, prior injuries to the same body areas, prior lawsuits, and prior insurance claims. The defense uses these to argue pre-existing conditions reduce the current case value.
How Long Depositions Typically Last
Most personal injury depositions last one to four hours. Simple cases often finish under two hours; complex ones with extensive medical history run longer. Understanding where depositions fit in the overall PI case timelines helps set realistic expectations.
You can request breaks during the deposition. Most attorneys agree to a short break roughly every hour. During breaks, avoid discussing the substance of your testimony with anyone, including your own attorney, while a question is technically still pending.
Common Deposition Mistakes That Hurt a Case
- Volunteering information: the most common and costly mistake. Answer only what was asked. Every additional sentence you provide is additional material for the opposing attorney to work with.
- Guessing: if you do not know or do not remember, say so directly. “I don’t recall” is a complete, truthful, and legally appropriate answer. A wrong guess that contradicts a document is far more damaging than an honest admission of uncertainty.
- Answering before the question is finished: wait for the full question before responding. Interrupting or anticipating the question leads to answers that do not actually address what was asked.
- Getting emotional or combative: remain calm throughout. Emotional outbursts damage credibility with the opposing attorney, who is assessing how the plaintiff will perform at trial.
- Nodding or gesturing: the court reporter can only transcribe words. All answers must be verbal and clear. “Mm-hmm” does not produce a clear record.
- Failing to ask for clarification: if a question is confusing, compound, or contains incorrect assumptions, say so and ask for it to be rephrased. You are not required to answer a question you genuinely do not understand.
What Happens After a Deposition
Reviewing the Transcript
After the deposition, the court reporter produces a transcript. In most states, the witness can review it and submit corrections via an errata sheet. For attorneys managing case documentation and review workflows, having a structured system for tracking deposition transcripts and corrections is an important part of organized case management.
How Depositions Influence Settlement Negotiations
Deposition testimony directly affects the insurer’s settlement position. A plaintiff who testifies clearly, consistently, and with composure is a more credible witness for trial. That credibility increases the insurer’s perceived risk of going to trial and makes a higher settlement offer more likely.
Conversely, inconsistent or damaging testimony gives the defense ammunition to challenge the plaintiff’s credibility at trial. That reduces the insurer’s perceived risk and gives them grounds to lower the offer or hold firm at a lower number.
When a Second Deposition Might Be Needed
A second deposition is uncommon and requires court permission and good cause, such as new evidence or a significant change in the plaintiff’s medical condition. Courts generally limit second depositions to avoid unnecessary burden on witnesses.
Deposition to Settlement: What the Timeline Looks Like
The path from deposition to settlement varies by case complexity and jurisdiction, but the general sequence is consistent across most personal injury matters. Understanding the full accident lawsuit timeline helps set realistic expectations for how long each phase takes.
- Discovery phase: depositions are conducted alongside other discovery activities including document requests, interrogatories, and expert designations. This phase typically lasts three to twelve months depending on case complexity.
- Post-discovery assessment: after all depositions are complete, each side evaluates the strength of their position. Settlement discussions often intensify at this point because the evidence picture is now complete.
- Mediation: many personal injury cases go through mediation before trial. A neutral mediator facilitates negotiation between the parties. Deposition testimony forms a significant part of each side’s assessment going into mediation.
- Settlement or trial: the majority of personal injury cases settle before reaching trial. Cases that settle typically do so within weeks to a few months after depositions conclude. Cases that cannot settle proceed to trial, where deposition transcripts become a tool for impeaching inconsistent witnesses.
