Jurisdictional discovery is a narrow, court-authorized investigation into whether a federal court has personal jurisdiction over a particular defendant. It usually begins after the defendant files a motion to dismiss under Federal Rule of Civil Procedure 12(b)(2), and it exists for a practical reason: the facts that prove jurisdiction, including contracts, sales data, marketing records, and internal communications, often sit inside the defendant’s own files.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented Without a chance to see those records, a plaintiff with a legitimate case could be dismissed out of court for lack of proof the defendant is keeping to itself.
What You Need to Show to Get It
The threshold for obtaining jurisdictional discovery varies by federal circuit, and there is no single national standard.2Washington and Lee University School of Law. Jurisdictional Discovery in United States Federal Courts
Several circuits require a prima facie showing before authorizing discovery. Under this approach, your complaint has to allege enough facts to support a reasonable inference that the court has authority over the defendant, assuming the allegations are true. The Eleventh Circuit has held that a district court does not abuse its discretion by denying jurisdictional discovery when the complaint is insufficient as a matter of law to establish a prima facie case of jurisdiction.3United States Court of Appeals for the Eleventh Circuit. World Media Alliance Label, Inc. v. Believe SAS
Other circuits are more forgiving. The D.C. Circuit uses what it calls a “quite liberal” standard that does not require a full prima facie case. The Second Circuit has permitted discovery where the plaintiff made a “sufficient start” toward establishing jurisdiction.2Washington and Lee University School of Law. Jurisdictional Discovery in United States Federal Courts
What no circuit permits is a fishing expedition. The request has to be tied to specific jurisdictional facts you have reason to believe exist, and you carry the burden of showing the discovery is likely to uncover material facts that are not already available.
General Jurisdiction vs. Specific Jurisdiction
The type of jurisdiction you are trying to establish dictates what you will be looking for, so this choice comes before anything else.
General jurisdiction lets a court hear any claim against a defendant, whether or not the dispute connects to the forum. For corporations, the Supreme Court narrowed this sharply in 2014, holding that general jurisdiction exists only where a corporation is “essentially at home,” which usually means the state of incorporation or the principal place of business.4Justia US Supreme Court. Daimler AG v. Bauman, 571 U.S. 117 (2014) Discovery aimed at general jurisdiction looks for a deep, continuous corporate presence. It is a hard bar.
Specific jurisdiction is the more common target. It allows a court to hear claims that arise directly from a defendant’s activities in the forum. The defendant does not need an office there, but the lawsuit itself must connect to something the defendant did in or directed toward the state.5Legal Information Institute. Specific Jurisdiction Discovery here focuses on purposeful contacts: contracts, sales, advertising, and other commercial conduct that gave rise to the claims.
Filing the Motion for Leave
You open the process by filing a motion for leave to conduct discovery limited to the issue of personal jurisdiction, in response to the defendant’s motion to dismiss.6U.S. Department of Justice. Plaintiffs Motion for Leave to Conduct Discovery Limited to the Issue of Personal Jurisdiction A workable motion does three things.
It asks the court to stay the pending motion to dismiss so the judge does not rule before you have gathered the facts. It defines the scope: the documents you need, the people you want to depose, and the interrogatories you plan to serve. And it proposes a realistic timeframe. Courts have little patience for open-ended jurisdictional investigations.
If the motion is granted, the court issues a scheduling order holding the dismissal motion in abeyance and setting a firm discovery deadline. After that deadline, courts typically allow supplemental briefing so the newly discovered facts can be folded into your opposition to the motion to dismiss.
Evidence Worth Chasing
Discovery requests should be built around facts that tie the defendant to the forum, not the defendant’s business in general. Common targets include:
- Business registration and licensing records, including certificates of authority, registered agent designations, and state tax filings.
- Physical presence indicators such as leases, property ownership records, and office utility accounts.
- Contracts with forum-state customers, vendors, or partners, especially those with performance tied to the forum.
- Marketing and advertising data, including digital campaigns, geotargeted ads, and local media buys aimed at forum-state residents.
- Employee and payroll records showing staff who worked in, traveled to, or were stationed in the forum.
- Sales and revenue data covering the volume of transactions with forum-state customers, revenue derived from the forum, and service calls or deliveries made there.
Interrogatories should ask pointed questions about operations in the forum rather than broad questions about the entire business. Document requests should target internal communications about expansion plans, regional partnerships, or market strategies focused on the forum. For depositions, start from organizational charts to identify regional managers, heads of sales, or compliance officers with firsthand knowledge of the defendant’s activity in the area.
Proportionality Limits
Federal Rule of Civil Procedure 26(b)(1) requires all discovery to be “proportional to the needs of the case,” and that constraint bites especially hard here, where the exercise is already supposed to be narrow.7Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Courts weigh the importance of the jurisdictional issue, the amount in controversy, each side’s relative access to the information, and whether the burden outweighs the likely benefit.
Requests for electronically stored information face an extra hurdle. Under Rule 26(b)(2)(B), a party does not have to produce ESI from sources that are not reasonably accessible due to undue burden or cost.7Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery A court can still compel it on a showing of good cause, but expect resistance if archived emails or legacy databases would duplicate what readily available business records already show. Courts will also cut off cumulative or duplicative discovery.
When the Defendant Is Foreign
Two frameworks complicate jurisdictional discovery against foreign parties: the Hague Evidence Convention and the Foreign Sovereign Immunities Act.
Hague Evidence Convention
In Société Nationale Industrielle Aérospatiale v. U.S. District Court (1987), the Supreme Court held that the Hague Convention on the Taking of Evidence Abroad is not the exclusive route for obtaining discovery from foreign parties. Once a court has jurisdiction, the Federal Rules remain available and the Hague procedures are optional, subject to a balancing test that weighs the case’s facts, sovereign interests, and whether Hague procedures would actually work.
The harder question is what happens before jurisdiction has been resolved. Some federal courts allow jurisdictional discovery under the Federal Rules against contested foreign defendants. Others require initial discovery to proceed through the Hague Convention until jurisdiction is decided. The Hague route is slower, costlier, and limited in scope, since many signatories have invoked Article 23 to refuse pretrial document production requests.
Foreign defendants have a reason to cooperate anyway. In Insurance Corp. of Ireland v. Compagnie des Bauxites de Guinea (1982), the Supreme Court held that a court can treat personal jurisdiction as established, by way of sanction, when a foreign defendant refuses to respond to jurisdictional discovery.
Foreign Sovereign Immunities Act
When the defendant is a foreign government or an agency or instrumentality of one, the standard tightens. Discovery against a sovereign must be ordered “circumspectly and only to verify allegations of specific facts crucial to the immunity determination.”8GovInfo. The Foreign Sovereign Immunities Act: A Guide for Judges, Second Edition The complaint has to contain concrete allegations supporting discovery, and courts will deny requests built on conclusory jurisdictional theories. You need to show that further information would materially affect the immunity analysis and that discovery would not be futile.
Sanctions for Refusing to Comply
When a court orders jurisdictional discovery and a party ignores it, Federal Rule of Civil Procedure 37 gives the court real power. Under Rule 37(b)(2)(A), if a party disobeys a discovery order, the court may:9Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
- Treat contested facts as established, deeming the jurisdictional facts to be whatever the requesting party claims.
- Bar the disobedient party from raising defenses, so a defendant who stonewalls could lose the right to contest jurisdiction entirely.
- Strike the motion to dismiss or other pleadings.
- Enter default judgment against the noncomplying party.
- Hold the party in contempt, with the penalties that follow.
On top of any of those, the court must order the disobedient party or its attorney to pay reasonable expenses, including attorney’s fees, caused by the failure, unless the failure was substantially justified.9Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Before choosing a sanction, courts weigh bad faith, prejudice to the other side, the need for deterrence, and whether a lesser sanction would work. Ignoring the order is a bad bet.
After the Discovery Window Closes
When the deadline passes, the court evaluates what the record now shows. Some judges hold an evidentiary hearing with live testimony to resolve conflicting factual claims. More often, the court rules on the papers using the supplemental briefing.
If the evidence falls short, the court grants the motion to dismiss, usually without prejudice. The case is not dead; it has to be refiled somewhere that does have jurisdiction. If the evidence establishes jurisdiction, the motion to dismiss is denied and the litigation moves on to merits discovery.
Appealing the Ruling
Discovery orders, including orders granting or denying jurisdictional discovery, generally are not immediately appealable. They sit within the trial court’s discretion over case management, and the collateral-order doctrine rarely reaches them.
Three alternative paths exist if you believe the court got it badly wrong. You can seek a certified interlocutory appeal under 28 U.S.C. § 1292(b), which requires the trial judge to certify a controlling question of law on which there is substantial ground for disagreement. You can petition for a writ of mandamus asking the appellate court to order the trial court to change course. Or, if you are the party under a discovery order, you can refuse to comply, accept a contempt finding, and appeal the contempt to challenge the underlying order. That last option is high-risk and should not be anyone’s first choice.
The practical move in most cases is to preserve the objection and raise it after final judgment. A wrongful assertion of jurisdiction becomes a ground for reversal on appeal; a wrongful denial dismissing the case is itself a final, appealable order.
