Discovery
Discovery: The pretrial process in which parties obtain information and evidence from each other and from nonparties.

What discovery means
In practice, you will see discovery in pleadings, motions, orders and court rules. The definition above explains the general meaning. Even so, the meaning can shift with context. Therefore, always read it alongside the rule or document where it appears.
Where discovery comes up
For example, the term appears in these procedures:
- Initial Disclosures (Fed. R. Civ. P. 26(a)(1)): information each party must share without being asked, such as people likely to have discoverable information and documents it may use.
- Interrogatories (Fed. R. Civ. P. 33): written questions one party serves on another party, answered in writing under oath.
- Requests for Production of Documents (Fed. R. Civ. P. 34): requests that another party produce documents, electronically stored information or tangible things, or permit inspection.
- Depositions (Fed. R. Civ. P. 30): questioning of a witness under oath, outside court, with a record made of the testimony.
How to research the term
To research discovery, begin with the rule, statute or contract where the word is used. Each one can give it a slightly different meaning. Then compare that text with how courts in your area have applied it. Also check the local rules of your court, since they can add requirements. If your case is in state court, the state rules control. So start with our state procedures guide to find them. In the end, always confirm that the source you rely on is current.
