Interrogatories

Interrogatories Explainer

Interrogatories are written questions that one party in a civil lawsuit directs to another party as part of discovery. They can ask for factual information, identify people with relevant knowledge, or seek explanations of a party's position. In United States federal civil litigation, Federal Rule of Civil Procedure 33 governs this tool. The questions are answered through a formal written process rather than a live interview. That makes interrogatories useful for gathering organized information that may later guide document requests, depositions, or other preparation.

The distinction between parties and outside witnesses is important. Interrogatories under this rule are directed to a party in the case, not simply to anyone who might possess useful information. An organization responds through an appropriate representative using information available to it. Answers are provided under oath, and objections are handled according to the rule. Attorneys have a role in formulating responses and objections, but the process should not be confused with a lawyer's informal description of what a client might say if questioned later.

Consider a dispute over a government contract. A party could ask the other side to identify employees involved in a decision or describe the basis for a claimed loss. The written response may point toward records or witnesses that need closer examination. Because there is no live follow-up, wording matters: an unclear question can produce an answer whose scope is uncertain. Interrogatories are consequently one tool among several, rather than a complete substitute for examining documents or testing a witness's account through deposition testimony.

Limits apply to the number and scope of interrogatories, and parties can object when a request exceeds the governing rules or protections. Federal defaults can be altered through authorized agreements or court orders, so a single number should not be treated as the rule for every lawsuit. Readers should distinguish an unanswered request, an objection, and a completed sworn response. A discovery dispute over written questions does not itself decide the underlying claims. Its significance lies in what information was sought, what was supplied, and how that information relates to the issues the court must eventually resolve.
