To challenge personal jurisdiction, file a motion to dismiss under Federal Rule of Civil Procedure 12(b)(2) — or its state-court equivalent — before you file an answer and before you file any other Rule 12 motion, and support it with a sworn declaration showing you lack the contacts with the forum state that the Constitution requires.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections Miss the timing or answer the complaint on its merits first, and the defense is gone for good. The court then proceeds as if it always had authority over you.
When You Have to Raise It
Personal jurisdiction is one of the defenses a defendant forfeits by engaging with a lawsuit’s substance before objecting. Two rules do the damage. Rule 12(h)(1) waives the defense if you file any Rule 12 motion without including it, or if you answer the complaint without pleading it as an affirmative defense. Rule 12(g)(2) requires you to consolidate every available Rule 12 defense into a single pre-answer motion; if you move to dismiss for failure to state a claim first and then try to raise personal jurisdiction in a separate motion later, the jurisdiction argument is waived.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections The same consolidation rule catches challenges to venue, process, and service of process. Bundle them or lose them.
State courts often frame the same idea through the older distinction between a “special appearance” and a “general appearance.” A special appearance lets you contest the court’s authority without submitting to it. A general appearance signals acceptance and waives the objection.2Legal Information Institute. Special Appearance Federal courts don’t use those labels, but the effect is identical: any request for relief on the merits, and often things as innocuous as asking for a continuance, can extinguish the defense depending on the jurisdiction. If jurisdiction is in doubt, raise it first, in writing, and do nothing else in the case until you have.
Consent You May Have Already Given
Before you spend time drafting, check whether you signed away the argument. A forum selection clause in a contract, employment agreement, or terms of service gives a designated court both personal jurisdiction and venue by advance agreement.3Legal Information Institute. Forum Selection Clause If the suit was filed in the forum named in that clause, a Rule 12(b)(2) motion will almost certainly fail unless the clause was unconscionable or procured by fraud.
What You’re Actually Arguing
A personal jurisdiction challenge is a two-step argument. First, does the forum state’s long-arm statute reach you? Some long-arm statutes extend to the full limits of the Constitution; others list specific triggers such as committing a harmful act in the state, owning property there, or entering a contract to be performed there. If the statute is narrow and your conduct doesn’t fit any category, you can win without ever reaching the constitutional question. Identify the exact statute and read its language.
Second, does exercising jurisdiction satisfy due process? The constitutional standard requires “minimum contacts” with the forum state such that suing you there does not offend “traditional notions of fair play and substantial justice.”4Legal Information Institute. Minimum Contacts Which version of that test applies depends on the type of jurisdiction the plaintiff is asserting.
General jurisdiction lets a court hear any claim against you, no matter where the events occurred, but only when you are “essentially at home” in the forum. For an individual, that generally means your state of residence. For a corporation, the Supreme Court in Daimler AG v. Bauman limited “at home” to the state of incorporation and the state of the principal place of business.5Justia. Daimler AG v. Bauman A company doing business in every state is not “at home” in every state.
Specific jurisdiction is narrower and comes up more often. It requires that the plaintiff’s claims arise from or relate to your contacts with the forum state, and that you purposefully directed activity there.6Congress.gov. Minimum Contact Requirements for Personal Jurisdiction7Legal Information Institute. Specific Jurisdiction A single product shipped into a state that injures someone there can be enough for a claim about that product, even where general jurisdiction would fail. The fight in specific-jurisdiction cases is whether your forum-related activity actually produced the lawsuit.8Legal Information Institute. Personal Jurisdiction
One boundary worth flagging for online defendants: running a nationally available website or payment platform does not by itself create jurisdiction in every state where someone uses it. What matters is whether you deliberately reached into a particular state’s market — shipping products there, targeting its consumers, contracting with residents — or whether the plaintiff simply happens to live there.
Pair It With a Service Challenge If You Have One
Even where contacts exist, the court’s authority over you doesn’t attach until you’re properly served. Federal Rule 4 permits personal delivery, leaving copies at your home with someone of suitable age and discretion who lives there, or delivery to an authorized agent; for corporations, service goes to an officer, managing agent, or registered agent.9Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Papers left with a neighbor who doesn’t live at your address, mailings sent to an old address, or service on an employee with no authority to accept process can all void jurisdiction.
Insufficient service is a Rule 12(b)(5) defense, and under the consolidation rule you have to raise it in the same motion as your Rule 12(b)(2) challenge or lose one of them.1Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections When both defects are available, put both in the motion.
Building the Motion
Start by gathering evidence of the absence of ties. Tax returns showing residency elsewhere, corporate registration confirming incorporation and headquarters in another state, and records showing no business activity in the forum state form the factual core. The more concrete and specific the record, the harder it is for the plaintiff to fight back.
The motion identifies the grounds — Rule 12(b)(2), plus Rule 12(b)(5) if service was defective — and explains why the court lacks authority. Federal filings generally go through the CM/ECF system; state courts use their own platforms.10United States Courts. Electronic Filing (CM/ECF) Federal court has no separate filing fee for a defendant’s motion to dismiss; the 28 U.S.C. § 1914 fee falls on the party who initiated the case.11Office of the Law Revision Counsel. United States Code Title 28 Section 1914 Some state courts charge modest motion fees.
The evidentiary backbone is a supporting affidavit or declaration signed under penalty of perjury. State plainly what you have not done in the forum: never lived there, never owned property there, never targeted its consumers, never entered a contract to be performed there. Address whatever theory of jurisdiction the complaint relies on directly. Misstatements in the declaration are federal perjury, punishable by fine and up to five years in prison.12Office of the Law Revision Counsel. United States Code Title 18 Section 1621 – Perjury Generally
After filing, serve the motion on the plaintiff’s attorney and file a certificate of service. The plaintiff’s response window runs 14 to 21 days under most local rules, though the number varies. The court may rule on the papers or set a hearing.
Who Has to Prove What
Once you file the motion, the burden shifts to the plaintiff to prove jurisdiction. You do not have to prove you lack contacts; the plaintiff has to prove the contacts are enough. On the papers alone, most circuits ask only for a “prima facie” showing — facts that, taken as true, would support jurisdiction. If the court holds an evidentiary hearing, the plaintiff usually has to prove jurisdiction by a preponderance of the evidence.
This is why the declaration carries so much weight. Specific sworn denials force the plaintiff to come forward with actual documentation of contracts, shipments, visits, or advertising directed into the state. Vague allegations in the complaint rarely survive concrete factual denials.
Jurisdictional Discovery Can Delay the Ruling
When the facts needed to resolve the dispute sit inside one party’s records, the court has discretion to allow limited jurisdictional discovery before deciding the motion. This can include document requests, interrogatories, and depositions, kept narrow to the jurisdictional question. A plaintiff has to show more than a hunch — typically a reasonable likelihood that discovery will produce evidence supporting jurisdiction, or at minimum a colorable jurisdictional claim. Where the complaint’s jurisdictional allegations are bare speculation against specific denials, courts deny the request and rule on the motion as filed. A strong motion does not always produce a fast ruling; expect the possibility of added months if discovery is allowed.
What Winning Actually Gets You
A dismissal for lack of personal jurisdiction is almost always without prejudice. The case isn’t decided on the merits, and the plaintiff can refile in a court that does have jurisdiction — your home state, a state where you conduct substantial business, or any other proper forum. You win the forum fight; you don’t necessarily end the lawsuit.
The strategic value shows up in the statute of limitations. Time spent litigating in the wrong forum does not always pause the filing clock. If the limitations period expires while the case sits in the improper court, the plaintiff may be barred from refiling even though the dismissal was without prejudice. Some states have savings statutes that grant extra time to refile after a dismissal, but those rules differ significantly. A successful challenge late in the limitations period can effectively end the case, without any court ever reaching the merits.
