What is discovery in a lawsuit?
Discovery is the stage of a lawsuit when each side gets the facts, documents and testimony the other side has before trial. Its usual tools are depositions, interrogatories, requests for admissions and requests for documents. In an injury case, it is when the defense digs into your medical history and you dig into theirs.

What happens in discovery in an injury case? An example
EXAMPLE ONLY. Marcus sues over a crash that he says injured his lower back. Here is what each side might ask for in discovery:
| The defense asks Marcus for | Marcus asks the defense for |
|---|---|
| Medical records for his back for the past several years | The other driver's phone records for the minutes before the crash |
| Pay stubs and tax returns to check his lost wages | Dash camera or company video |
| Photos, texts and posts about the crash and his activities | The driver's training and work schedule, if he was on the job |
| A deposition, where he answers questions under oath | The driver's deposition |
The records show Marcus saw a chiropractor three years earlier. That does not end his case, but he must explain it. A gap he hid would hurt far more than one he admits.
Why does discovery matter if you were hurt?
Discovery is where claims get tested. The scope is broad: any nonprivileged matter relevant to a claim or defense and proportional to the case. It does not even have to be something a jury would hear. Expect questions about prior injuries, other accidents and how your life has changed.
It also works for you. Discovery can turn up video, maintenance records or a phone log that an insurer never shared during the claim. Many cases settle once both sides see the same evidence.
Is discovery different in state court?
Each state sets its own rules, often modeled on the federal ones. Texas ties the amount of discovery to the size of the case. Suits where claimants seek only money of $250,000 or less go through an expedited process, and those suits follow a Level 1 discovery plan with tighter limits.
Discovery vs. the discovery rule
They sound alike but are unrelated. Discovery is evidence gathering inside a lawsuit. The discovery rule is a deadline idea used in some cases, such as some medical claims, where the time to sue starts when the injury was or should have been found. Check your state's deadline page for when it applies.
Questions
How long does discovery take in a personal injury case?
Often several months to a year or more, depending on the court's schedule and how many witnesses and doctors are involved.
Can they look at my social media?
Posts about the crash or your activities can be requested if they are relevant to your injuries. Do not delete anything once a claim starts. Ask before changing privacy settings.
Do I have to hand over all my medical records?
Usually only records relevant to the injuries in the case, though that can include earlier treatment of the same body part.
