Key Facts

Federal level: Civil discovery generally covers nonprivileged information relevant to a party’s claim or defense when the request is proportional to the needs of the case.
Federal level: Common discovery tools include document requests, interrogatories, requests for admission, and depositions.
Federal level: Courts can limit burdensome discovery, protect privileged material, compel proper responses, and impose sanctions for some discovery failures.

How discovery fits into a federal civil case

Discovery is the structured exchange of information before trial. In a federal civil case, it helps the parties identify the evidence, test factual positions, narrow disputes, and prepare issues for resolution. The Federal Rules of Civil Procedure provide the national framework, while each district court’s local rules and the judge’s scheduling orders can add case-specific requirements.

What information can federal civil discovery reach?

Federal Rule of Civil Procedure 26(b)(1) defines the basic scope. A party may obtain nonprivileged material that is relevant to a claim or defense and proportional to the needs of the case. Proportionality accounts for such considerations as the importance of the issues, the amount in controversy, access to relevant information, the parties’ resources, the value of the discovery in resolving the issues, and whether its burden or expense outweighs its likely benefit.

Discoverable information does not have to be admissible at trial. That distinction matters because discovery is designed to uncover and organize information, while the rules of evidence determine what a factfinder may hear. Privilege remains a separate boundary: attorney-client communications and protected trial-preparation material may be withheld when the governing requirements are met, and the withholding party generally must describe the claim of protection without revealing the protected information itself.

Rule 26 also requires reasonable steps to preserve electronically stored information when litigation makes preservation duties applicable. If relevant electronic information is lost because reasonable preservation steps were not taken, Rule 37(e) supplies the federal framework for deciding whether curative measures or more serious sanctions are warranted.

The main discovery tools

Depositions are sworn examinations recorded outside the courtroom. Rule 30 generally allows oral depositions of parties and nonparties, subject to limits and court control. Unless the parties stipulate or the court orders otherwise, a deposition is limited to one day of seven hours. A nonparty’s attendance ordinarily is compelled through a federal subpoena.

Interrogatories are written questions served on another party. Rule 33 ordinarily limits a party to 25 interrogatories, including discrete subparts, unless the court permits more or the parties stipulate otherwise. Answers and objections generally are due within 30 days, and answers must be made separately, fully, in writing, and under oath to the extent no objection applies. A dedicated explanation of interrogatories can help distinguish these questions from depositions and document requests.

Requests for production seek documents, electronically stored information, tangible items, or permission to inspect designated property. Rule 34 requires requests to describe the requested items or categories with reasonable particularity. The written response generally is due within 30 days, although a different period may result from a stipulation, court order, or the early-discovery timing rule.

Requests for admission ask another party to admit the truth of facts, the application of law to fact, opinions about either, or the genuineness of documents. Under Rule 36, a matter ordinarily is admitted unless a written answer or objection is served within 30 days. An admission under this rule is conclusively established for the pending action unless the court permits withdrawal or amendment.

Timing, disclosures, and the discovery plan

Discovery usually operates within a schedule rather than as an open-ended exchange. Rule 26(a) requires specified initial disclosures without awaiting a discovery request, subject to listed exemptions and exceptions. These disclosures generally identify people likely to have discoverable information, relevant documents or electronically stored information, damages computations, and certain insurance agreements.

Rule 26(d) generally bars most discovery before the parties confer under Rule 26(f), unless a rule, stipulation, or court order authorizes it. At that conference, the parties discuss claims and defenses, preservation, disclosures, and a proposed discovery plan. The court then manages the case through a scheduling order under Rule 16, which can set deadlines and tailor discovery to the dispute. A broader guide to the Federal Rules of Civil Procedure places these steps within the full life cycle of a federal civil action.

Objections, protective orders, and motions to compel

A discovery objection should identify its actual basis rather than function as a blanket refusal. Rules 33 and 34 require specific objections, and Rule 34 requires a responding party to state whether responsive materials are being withheld on the basis of an objection. Responses ordinarily must proceed as to portions not covered by an objection.

Rule 26(c) allows a court, for good cause, to enter a protective order against annoyance, embarrassment, oppression, or undue burden or expense. The order may forbid discovery, limit its scope, prescribe a different method, or protect confidential material. Before seeking that order, the moving party must certify a good-faith effort to resolve the dispute without court action.

Rule 37 governs motions to compel and many discovery sanctions. A motion to compel generally requires certification of a good-faith conference or attempt to confer. Depending on what happened, the court may order a response, allocate reasonable expenses, prohibit use of evidence, deem facts established, strike pleadings, stay proceedings, dismiss claims, or enter default judgment. The available consequence depends on the particular violation and the rule authorizing relief; sanctions are not automatic in every disagreement.

Discovery is not the same in every court

This article describes discovery under the federal civil rules. State courts use their own statutes and procedural rules, which may differ in scope, timing, disclosure duties, numerical limits, terminology, and available sanctions. Federal district courts also publish local rules, standing orders, and judge-specific practices. Those authorities do not replace the Federal Rules, but they can materially shape how discovery proceeds in a particular federal case.
