Discovery
The structured exchange of records, written answers, and sworn testimony between the two sides of a civil case, after a lawsuit is filed and before any trial.
Collision Bureau is not a law firm and this is not legal or medical advice. It is general information about what happens after a crash. For advice on your situation, talk to an attorney licensed in your state or a treating clinician.
What it means
Discovery is the pre-trial phase of a lawsuit where each side gets to see the records and testimony the other side will rely on. The purpose is to end surprise. Both sides enter trial, or settlement, knowing what the file actually contains, which is a feature of civil procedure and not a courtesy anyone extends.
In a crash case, discovery is where the police report, the medical records, the repair file, the policy documents, and the sworn accounts of the drivers all end up in both sides' hands at the same time. The file that gets argued about later is the file that gets assembled here.
How it works
Discovery uses a handful of named tools, each with its own rules. Interrogatories are written questions one side sends the other, answered under oath. Requests for production are written demands for documents, like medical records or the full insurance file. Requests for admission ask the other side to admit or deny specific factual statements. Depositions are live sworn questioning of witnesses. Subpoenas go to third parties, like hospitals and employers, to pull records that neither side holds directly.
A court-issued scheduling order sets deadlines for each piece and for the close of the phase as a whole. The parties can object to specific requests, and the court resolves the objections when they cannot. By the end of the phase, both sides have the same body of material to work from.
Why it comes up
Most crash claims never reach discovery because most crash claims resolve before anyone files a lawsuit. For the files that do become suits, discovery is the long middle. It is where injury claims are tested against medical records, where fault is tested against witness statements, and where the insurer's defense gets its first full look at the file the claimant's attorney has been building. If the case later enters mediation, both sides walk in with the same transcripts and the same documents on the table.
What it is not
Discovery is not a trial. No witness testifies in front of a jury during this phase, and no judge decides who wins. It is also not the demand package that often precedes a lawsuit, which is a one-sided presentation of the claimant's case. Discovery is two-sided, rule-bound, and run on the court's calendar.
Questions people actually ask
01Do I have to turn over all my records?
The scope of what you have to produce is set by rules of civil procedure, by the specific requests the other side serves, and by any objections your attorney raises. The general principle is that information relevant to the claim or defense is discoverable, which is broader than what later becomes evidence at trial. The exact lines in your file are drawn by your attorney and, when the sides disagree, by the court. There is no universal list that answers the question in advance.
02How long does discovery take?
Months, sometimes a year or more, depending on how complex the case is and on the court's own schedule. Civil cases run on a scheduling order that sets deadlines for each piece of discovery, and the parties often negotiate extensions. A simple two-car crash with modest injuries can close discovery relatively quickly. A case with multiple vehicles, disputed liability, or significant medical specials takes longer. The timeline on your file is a question for your attorney.
03Does discovery mean the case is going to trial?
No. Most civil cases that enter discovery settle before trial. Discovery is the phase that makes a serious settlement possible, because both sides finally see the records and sworn testimony each will rely on, and the real value of the case comes into focus. Trial happens on the files that do not settle after that. What a specific file is likely to do is a question for the attorneys handling it, not something any page can predict from the outside.
