What does interrogatories mean in law?

Interrogatories are a formal set of written questions submitted by one party in a lawsuit to another party, typically during the discovery phase of litigation. The receiving party is required to answer these questions in writing and under oath, providing relevant information that can help clarify the issues in the case. Interrogatories are used to gather facts, identify witnesses, and obtain details about the opposing party’s claims or defenses. They are an essential tool for building a case and preparing for trial.
