Personal jurisdiction over a natural person is a different problem from personal jurisdiction over a corporation, and treating them as one doctrine is the most common error in motion practice. A corporation has a "home" by legal fiction — place of incorporation and principal place of business — and a body of case law about when its contacts with a forum are "continuous and systematic." An individual has a domicile, a body, and a set of intentional acts. The doctrinal tools are the same words; their application is not.
This guide covers what actually decides these motions: where the person is domiciled, whether they were served inside the forum, what they purposefully did there, and — the step most often skipped — whether the federal court's service authority under Rule 4 reaches them at all.

Two questions, not one
Every personal-jurisdiction analysis in federal court has two independent parts, and a defendant can win on either.
- Is there a statute or rule authorizing service on this defendant? For most federal cases the answer comes from Rule 4(k)(1)(A), which borrows the long-arm statute of the state in which the district court sits.
- Does the exercise of jurisdiction satisfy due process? For a state-borrowed long-arm, the Fourteenth Amendment; for a federal statute authorizing nationwide service, the Fifth.
Omni Capital Int'l, Ltd. v. Rudolf Wolff & Co. is the case to know, because it holds that the first question is real. The plaintiffs there argued that because the defendants' conduct satisfied due process, the federal court could reach them regardless of any authorizing rule. The Court refused: "before a court may exercise personal jurisdiction over a defendant, there must be more than notice to the defendant... There also must be a basis for the defendant's amenability to service of summons. Absent consent, this means there must be authorization for service of summons on the defendant." The Court declined to create a federal common-law service rule to fill the gap Congress had left in the Commodity Exchange Act.
The practical lesson: when a plaintiff sues under a federal statute with no nationwide-service provision, the federal court in Nevada has no more reach over a Delaware individual than a Nevada state court would. That is a frequently decisive point, and it is available only if raised.
The Rule 4(k) borrowing rule
Rule 4(k)(1) authorizes service that establishes jurisdiction over a defendant:
- (k)(1)(A) — who is subject to the jurisdiction of a court of general jurisdiction in the state where the district court is located. This is the workhorse, and it means state long-arm law governs in the overwhelming majority of federal cases.
- (k)(1)(B) — the 100-mile "bulge" provision, for parties joined under Rule 14 or Rule 19 and served within 100 miles of the place where the summons issued.
- (k)(1)(C) — when authorized by a federal statute.
- (k)(2) — the federal long-arm for claims arising under federal law against a defendant not subject to jurisdiction in any state's courts, so long as the exercise is consistent with the Constitution.
Some states' long-arm statutes reach as far as due process allows, collapsing the two questions. Many do not. An enumerated-act long-arm can defeat jurisdiction that due process would permit, and an argument confined to due-process minimum contacts forfeits that ground.
Federal statutes with nationwide service change the calculus entirely. 18 U.S.C. § 1965 (RICO), 15 U.S.C. § 22 (Clayton Act), 15 U.S.C. § 78aa (Exchange Act), and 29 U.S.C. § 1132 (ERISA) each authorize service beyond the forum state. Where they apply, the relevant sovereign is the United States, and the contacts inquiry — if there is one at all — is national.
Domicile and general jurisdiction over a person
A natural person is subject to all-purpose jurisdiction at their domicile, and the rule has never been seriously questioned. Milliken v. Meyer is the source: Wyoming could enter a personal judgment against a Wyoming domiciliary served in Colorado, because "domicile in the state is alone sufficient to bring an absent defendant within the reach of the state's jurisdiction for purposes of a personal judgment by means of appropriate substituted service." Milliken also supplies the phrase later borrowed for the corporate context — jurisdiction is proper where maintaining the suit does not offend "traditional notions of fair play and substantial justice."
Milliken answers the general-jurisdiction question for individuals in a single word: domicile. There is no individual analogue of the corporate "at home" litigation that Goodyear Dunlop Tires Operations, S.A. v. Brown and Daimler AG v. Bauman generated, because an individual's affiliations are not distributed across a corporate-form fiction. A person who lives in Ohio can be sued in Ohio for anything, including conduct wholly outside Ohio.
Domicile is residence plus intent to remain, and it does not change merely because someone moves temporarily. Practitioners who conflate domicile with residence create two problems at once: a defective jurisdictional allegation and, in diversity cases, a defective § 1332 allegation. The same domicile inquiry does double duty.
Tag jurisdiction: Burnham and in-state service
Physical service on an individual inside the forum state confers jurisdiction over that individual for any claim, related or not. Burnham v. Superior Court of California, County of Marin confirmed the rule in 1990 — a New Jersey resident served with California divorce papers while on a short business trip to California, partly to visit his children, was subject to California's jurisdiction on claims having nothing to do with his visit.
Burnham is important for what it reveals about the structure of the doctrine. The Court was unanimous on the result and fractured on the reasoning. Justice Scalia's plurality treated in-state service as valid because it was a "continuing tradition of our legal system" predating International Shoe, and therefore not subject to a minimum-contacts overlay at all. Justice Brennan concurred on the ground that tag service satisfies contemporary due process because a defendant who avails himself of the forum's benefits during his visit has fair warning. That split matters: the plurality's view makes tradition self-justifying, while the concurrence's view invites case-by-case challenge in extreme circumstances.
Two limits are worth remembering. First, service procured by fraud or enticement into the forum is generally not effective — courts will not honor a plaintiff who lures a defendant across the state line. Second, tag jurisdiction reaches individuals; whether it reaches corporations through service on a corporate officer present in the forum is a separate and much-contested question that Mallory v. Norfolk Southern Railway Co. has now reframed around consent-by-registration rather than presence.
From Pennoyer to International Shoe
The modern framework replaced a territorial one, and the replacement was not a small adjustment.
Pennoyer v. Neff held in 1878 that a state's judicial power is coextensive with its physical borders: a state court could bind a person present within the state or property located within it, but a personal judgment against a nonresident served by publication was void. Hess v. Pawloski exposed the limits of that model in an automobile age. Massachusetts made nonresident motorists appoint the registrar as agent for service as an implied condition of using state highways. The Court upheld it — a transparent fiction, but one Pennoyer forced on the states because the alternative was immunity for out-of-state drivers.
International Shoe Co. v. Washington replaced the fictions in 1945 with the formulation everything since has elaborated: a defendant not present in the forum may be subject to jurisdiction if it has "certain minimum contacts with it such that the maintenance of the suit does not offend traditional notions of fair play and substantial justice." The opinion also contains the first sketch of the general/specific distinction, in the now-familiar passage distinguishing continuous and systematic activity giving rise to the claim from isolated activity unrelated to it.
McGee v. International Life Ins. Co. marks the outer edge of the expansion: a single reinsurance contract mailed into California, on a policy paid from California, was enough for California to entertain a suit by the beneficiary. Hanson v. Denckla, three years later, supplied the brake and the phrase that has done the most work since — jurisdiction requires "some act by which the defendant purposefully avails itself of the privilege of conducting activities within the forum State, thus invoking the benefits and protections of its laws." Hanson rejected Florida's attempt to reach a Delaware trustee whose only connection to Florida was that the settlor had moved there. The unilateral activity of a third party is not the defendant's contact.
Specific jurisdiction: purposeful availment by an individual
Specific jurisdiction requires contacts that the defendant created and a claim that arises out of or relates to them. Three cases carry most of the weight, and only one of them involves an individual.
World-Wide Volkswagen Corp. v. Woodson held that Oklahoma could not reach a New York retailer and regional distributor because an Audi sold in New York was driven into Oklahoma and burned there. The foreseeability that matters "is not the mere likelihood that a product will find its way into the forum State," but "that the defendant's conduct and connection with the forum State are such that he should reasonably anticipate being haled into court there." World-Wide Volkswagen also introduced the stream-of-commerce metaphor that Asahi Metal Industry Co. v. Superior Court later split the Court over, and that remains unresolved after J. McIntyre Machinery, Ltd. v. Nicastro. For individuals the metaphor rarely matters; what matters is the purposeful-availment core.
Burger King Corp. v. Rudzewicz is the individual-defendant case worth reading closely, because it is the Court's fullest treatment of a natural person's contract-based contacts. Rudzewicz was a Michigan resident who never set foot in Florida but negotiated a twenty-year franchise agreement with a Miami-headquartered franchisor, agreed to Florida choice of law, and mailed payments to Miami. The Court sustained Florida jurisdiction and made four points that recur in every brief since:
- A contract with an out-of-state party is not by itself enough; courts look to prior negotiations, contemplated future consequences, the terms of the contract, and the parties' actual course of dealing.
- A choice-of-law clause, though not dispositive, "reinforced his deliberate affiliation with the forum State."
- Physical entry into the forum is not required — "it is an inescapable fact of modern commercial life that a substantial amount of business is transacted solely by mail and wire communications across state lines."
- The "purposeful availment" requirement exists to ensure a defendant is not haled into a forum "solely as a result of random, fortuitous, or attenuated contacts," or of "the unilateral activity of another party or a third person."
Burger King also states the two-step structure explicitly: once minimum contacts are shown, they may be considered alongside other factors to determine whether jurisdiction is reasonable, and a defendant who has purposefully directed activities at the forum "must present a compelling case that the presence of some other considerations would render jurisdiction unreasonable."
Note the individual/corporate asymmetry that Burger King declined to adopt. Rudzewicz argued that as an individual franchisee he had weaker bargaining power and should be treated differently than a corporate counterparty. The Court considered the argument on the reasonableness side and rejected it on the facts, but it did not create a separate, softer standard for natural persons. That remains true: individuals get the same test, not a gentler one.
Ford Motor Co. v. Montana Eighth Judicial Dist. Court matters for the relatedness half of the inquiry. The Court held in 2021 that "arise out of or relate to" is disjunctive — the second phrase "contemplates that some relationships will support jurisdiction without a causal showing." Ford's extensive in-state marketing and servicing of the same vehicle models supported jurisdiction over claims involving used cars Ford had originally sold elsewhere. For individual defendants this cuts both ways: a claim need not be caused by the forum contacts, but Ford also insists the relationship be a real one, not a but-for chain.
The effects test: Calder, Keeton, and Walden
Intentional-tort claims against individuals almost always run through the effects test, and the test has narrowed sharply.
Calder v. Jones sustained California jurisdiction over a Florida reporter and editor who wrote a National Enquirer story about a California entertainer. The Court emphasized that the article concerned the California activities of a California resident, was drawn from California sources, and caused reputational injury in California, where the magazine had its largest circulation — the defendants' "intentional, and allegedly tortious, actions were expressly aimed at California." Keeton v. Hustler Magazine, Inc., decided the same day, allowed a New Hampshire libel suit by a plaintiff with no New Hampshire connection, because the magazine's regular circulation of 10,000 to 15,000 copies there was itself a sufficient contact for a claim arising from that circulation.
For twenty years Calder was read expansively, with many courts holding that intentionally harming a plaintiff known to live in the forum satisfied express aiming. Walden v. Fiore ended that reading in 2014, and it is now the first case to cite in any individual-defendant tort motion. A Georgia-based DEA agent seized cash from Nevada residents at an Atlanta airport and allegedly drafted a false probable-cause affidavit knowing the plaintiffs lived in Nevada. The Ninth Circuit found jurisdiction; the Supreme Court reversed unanimously. Two holdings:
- The forum contacts must be the defendant's own, not the plaintiff's. "The proper question is not where the plaintiff experienced a particular injury or effect but whether the defendant's conduct connects him to the forum in a meaningful way." A defendant's relationship with a plaintiff who happens to reside in the forum "is an insufficient basis for jurisdiction."
- **Calder was about the forum, not the plaintiff.* The Calder* article's reputational harm occurred in California because that is where the plaintiff's reputation existed and where the audience was; the tort itself, not merely its victim, was connected to the forum.
Walden disposes of a large fraction of what used to be filed. Knowledge that the plaintiff lives in the forum is not express aiming. A phone call or email to a forum resident, standing alone, is not purposeful availment. The defendant must have done something in or toward the forum.
Family and support cases: the Kulko problem
Kulko v. Superior Court of California is a separate line worth knowing because family cases generate more individual-defendant jurisdiction motions than any other category. A New York father agreed that his daughter could live with her mother in California and bought her a plane ticket. California asserted jurisdiction over him for increased child support. The Court reversed. Acquiescing in a child's move, and paying for the flight, did not amount to purposefully availing himself of California's benefits; the "effects" of his conduct in California were not the kind that justify jurisdiction, and the Court declined to treat a parent who allows a child to relocate as having transacted business in the destination state.
Kulko has been substantially bypassed in practice, not overruled. The Uniform Interstate Family Support Act — enacted in every state and reinforced by federal conditions on child-support funding — supplies statutory long-arm bases specifically designed to cover the Kulko fact pattern, including provisions reaching a parent who resided with the child in the state or who caused the child's conception there. Two consequences follow. First, in a support case, read the UIFSA long-arm before the due-process case law; the statute usually supplies the answer. Second, Kulko's due-process holding still binds where no statutory basis applies, and it remains the strongest authority for the proposition that private family arrangements are not forum-directed conduct.
Property-based jurisdiction after Shaffer
Quasi in rem jurisdiction — attaching a defendant's in-state property to support a personal judgment on an unrelated claim — was a Pennoyer artifact, and Shaffer v. Heitner abolished it in 1977. Delaware had sequestered the stock of nonresident officers and directors of a Delaware corporation to compel their appearance in a derivative suit about conduct in Oregon. The Court held that "all assertions of state-court jurisdiction must be evaluated according to the standards set forth in International Shoe and its progeny," and that ownership of property in the forum is simply one contact to be weighed, not an independent basis.
Shaffer left two things intact. Where the claim is about the property — title, foreclosure, partition, a lien — the property's location will nearly always supply the necessary contacts, because the dispute and the forum's interest coincide. And jurisdiction to enforce an existing judgment against in-state assets is unaffected; Shaffer governs the power to adjudicate, not the power to execute.
Rush v. Savchuk applied Shaffer to the insurance-garnishment device: Minnesota could not manufacture jurisdiction over an Indiana driver by treating the obligation of his insurer, which did business in Minnesota, as an attachable in-state debt. The insurer's contacts are not the insured's.
Consent, waiver, and forum-selection clauses
Personal jurisdiction protects a liberty interest, and a liberty interest can be given up. Insurance Corp. of Ireland v. Compagnie des Bauxites de Guinee states the principle and its consequence: "the personal jurisdiction requirement recognizes and protects an individual liberty interest," so unlike subject-matter jurisdiction it "can, like other such rights, be waived." The Court upheld a Rule 37 sanction establishing jurisdictional facts against defendants who refused discovery on the jurisdictional question.
Waiver happens more often by inadvertence than by agreement. Under Rule 12(h)(1), a personal-jurisdiction defense is waived if omitted from a Rule 12 motion made before the responsive pleading, or if not raised in the answer or an amendment allowed as of course under Rule 15(a)(1). The defense also evaporates through conduct: affirmative counterclaims, extensive merits discovery, and long delay have all been held to forfeit it even when it was properly pleaded.
Advance consent is fully effective. National Equipment Rental, Ltd. v. Szukhent enforced a lease clause appointing a named New York agent for service — a person the Michigan farmers had never met, and who happened to be the plaintiff's officer's wife — because the clause was voluntarily given and the agent promptly forwarded the papers.
Forum-selection clauses are the modern mechanism. M/S Bremen v. Zapata Off-Shore Co. established that such clauses are "prima facie valid" and should be enforced unless the resisting party shows enforcement would be unreasonable — a showing requiring fraud or overreaching, grave inconvenience amounting to deprivation of a day in court, or contravention of a strong public policy of the forum. Carnival Cruise Lines, Inc. v. Shute extended Bremen to a non-negotiated consumer form contract, enforcing a Florida forum clause printed on a cruise ticket against Washington passengers.
The procedural consequence is important. Atlantic Marine Constr. Co. v. United States Dist. Court holds that a forum-selection clause pointing to another federal district is enforced through 28 U.S.C. § 1404(a) transfer, not through a § 1406 or Rule 12(b)(3) dismissal, because a clause does not render an otherwise-proper venue "wrong." When the clause points to a state or foreign court, the vehicle is forum non conveniens. And the clause shifts the burden: the plaintiff's choice of forum "merits no weight," and the party defying the clause bears the burden of showing transfer is unwarranted.
Reasonableness: the second step nobody wins on
Once minimum contacts exist, the court asks whether jurisdiction is nonetheless unreasonable. Asahi Metal Industry Co. v. Superior Court lists the factors: the burden on the defendant, the forum state's interest, the plaintiff's interest in convenient and effective relief, the interstate judicial system's interest in efficient resolution, and the shared interest of the states in furthering fundamental substantive social policies. Asahi is also the rare case decided on this step — the Court found California's exercise unreasonable where both the plaintiff's claim had settled and the remaining dispute was an indemnification claim between a Japanese and a Taiwanese manufacturer.
For domestic individual defendants, reasonableness almost never carries the day. Burger King sets the bar: the defendant must "present a compelling case." Distance, expense, and inconvenience are not enough, because those burdens exist in every out-of-state suit. The factor that occasionally matters is the defendant's status as a foreign national facing claims with little connection to the United States — the Asahi posture — and that argument belongs to a foreign defendant, not to a defendant who merely lives two states away.
Litigating the motion
Burden and standard. The plaintiff bears the burden of establishing jurisdiction. On a Rule 12(b)(2) motion decided on the papers, most circuits require only a prima facie showing, with the pleadings and affidavits read in the plaintiff's favor and conflicts resolved against the movant. If the court holds an evidentiary hearing or defers to trial, the standard rises to preponderance. Choosing between those postures is a tactical decision: a defendant with strong affidavits often wants a hearing, and a plaintiff with thin facts wants the paper standard.
Jurisdictional discovery. Courts routinely permit targeted discovery where the plaintiff makes a threshold showing that discovery could establish contacts. A request must be specific; "we would like to explore the defendant's contacts" is denied. Note the sanction available in Insurance Corp. of Ireland: a defendant who resists jurisdictional discovery under Rule 37 may have the jurisdictional facts established against it.
Sequencing with subject-matter jurisdiction. Ruhrgas AG v. Marathon Oil Co. holds there is no rigid priority: a district court may dismiss for lack of personal jurisdiction without first resolving a difficult subject-matter question, particularly where the personal-jurisdiction issue is straightforward. Sinochem Int'l Co. v. Malaysia Int'l Shipping Corp. goes further, permitting a forum non conveniens dismissal before resolving either, because such a dismissal is a non-merits determination. Both cases are useful to a defendant who would rather not litigate the harder question.
Preserve and preserve again. Raise the defense in the first Rule 12 motion or the answer. Do not file a counterclaim, do not move to compel merits discovery, and do not let the motion sit unresolved through a year of active litigation.
Waiver by removal does not happen. Removing a case to federal court does not waive a personal-jurisdiction objection; the removed defendant may still move under Rule 12(b)(2). Conversely, a Rule 12(b)(2) motion does not waive venue or forum non conveniens arguments if they are raised together.
Practice checklist
- Identify the service authority first. Rule 4(k)(1)(A) and the forum state's long-arm, or a federal nationwide-service statute. Omni Capital is a complete defense where neither exists.
- Read the state long-arm text. If it is enumerated rather than coextensive with due process, argue the statute before the Constitution.
- Check domicile. A domiciliary is subject to general jurisdiction under Milliken, and the analysis stops.
- Check the manner of service. In-state personal service ends the inquiry under Burnham.
- *For intentional torts, start with Walden.* Ask what the defendant did in or toward the forum, ignoring where the plaintiff felt the harm.
- *For contract claims, run the Burger King factors.* Negotiations, contemplated consequences, contract terms, course of dealing, and any choice-of-law clause.
- *Test relatedness under Ford.* "Relate to" is disjunctive, but it is not a but-for test.
- Look for consent. Forum-selection clauses, agent-appointment clauses, and registration statutes. If a clause points to another federal district, the remedy is § 1404(a) transfer, not dismissal.
- Ask for jurisdictional discovery with specificity, or oppose it as a fishing expedition.
- Consider the alternative exits. § 1404(a) transfer, § 1406 transfer for improper venue, or forum non conveniens under Gulf Oil and Piper Aircraft may be better outcomes than a dismissal the plaintiff can cure by refiling.
Frequently asked questions
Can a federal court exercise jurisdiction over a defendant that the forum state's courts could not reach? Generally no. Rule 4(k)(1)(A) ties the district court to the forum state's reach. The exceptions are a federal statute authorizing broader service, the Rule 4(k)(1)(B) 100-mile bulge, and Rule 4(k)(2)'s federal long-arm for federal claims against defendants not amenable anywhere in the United States.
Does serving someone at the airport during a layover create jurisdiction? Burnham says in-state personal service suffices, and the plurality would not qualify it. Justice Brennan's concurrence reserved doubt about the most attenuated presence, and a few lower courts have declined to extend tag jurisdiction to a defendant who never left a secure transit area. The safe reading: brief but voluntary presence is enough; service procured by trickery is not.
Is an individual defendant's email or phone call into the forum a contact? It can be, but only as part of a course of purposeful conduct. Burger King confirms that physical entry is unnecessary, while Walden confirms that communications directed at a person who happens to live in the forum, without more, are not express aiming at the forum itself.
Does a defendant's knowledge that the plaintiff lives in the forum matter? Not by itself, after Walden. The forum connection must arise from the defendant's own conduct, not from the plaintiff's residence.
Can a court assert jurisdiction because the defendant owns land in the state? Only where the claim relates to the property, or where ownership combines with other contacts. Shaffer eliminated property as a freestanding basis for unrelated claims, and Rush barred the insurance-garnishment workaround.
What happens if the individual defendant is a corporate officer? The corporation's contacts are not automatically the officer's. Most circuits apply a fiduciary-shield principle as a matter of state long-arm construction rather than due process, so the answer depends on the forum's law; but the officer's own forum-directed acts always count, and Walden was itself a suit against an individual federal agent acting in his official capacity.
Is there a different, easier standard for individuals than for companies? No. Burger King considered and declined to create one. The difference is factual — individuals have a single domicile and fewer contacts — not doctrinal.
