When one side in a civil case wants information from the other side, they can use a process called discovery. This means they can ask written questions (called interrogatories), request documents, or ask to inspect property. The other side must respond honestly and on time.
The parties are expected to work together and share information without the court having to get involved. If someone refuses to cooperate or ignores discovery requests, the other side can ask the judge to step in and order them to comply. A judge can also punish a party who refuses to follow discovery rules.
There are deadlines for completing discovery, and the court can set a schedule to keep things moving. If you are involved in a civil case, pay close attention to any discovery requests you receive, because ignoring them can seriously hurt your case.
