In the United States, discovery is a critical component of procedural law that allows parties to exchange information before a trial. By compelling adversaries to disclose evidence, the process helps parties prepare more thoroughly and reduces the element of surprise in civil litigation.1
Discovery facilitates trial preparation through several key mechanisms:
- Information Gathering: Parties can use interrogatories (written questions) and depositions (sworn oral testimony) to secure important facts and witness accounts.2
- Evidence Inspection: Parties may demand the production of relevant documents or tangible objects for inspection, and request medical examinations when a party’s physical or mental condition is at issue.21
- Strategic Evaluation: By revealing the strengths and weaknesses of a case early, discovery encourages settlement by helping parties understand the true value of their claims.1
- Efficiency: It allows for the early exposure of insubstantial claims, preventing them from proceeding to trial.1
While broad, this process is subject to limitations, such as attorney-client privilege and protections for materials prepared in anticipation of litigation.1
