Pennsylvania’s long-arm statute, 42 Pa. C.S. § 5322, lets state courts hear lawsuits against people and businesses located outside the Commonwealth when their conduct has a qualifying connection to Pennsylvania. The statute does two things at once. It lists ten specific activities that create jurisdiction, and it separately stretches a court’s reach to the fullest extent the U.S. Constitution allows. If you are suing someone who lives in another state, or you have been sued here and don’t, the statute decides whether a Pennsylvania court can hear the case at all.
The Ten Activities That Trigger Jurisdiction
Section 5322(a) lists the activities that place a non-resident within the reach of Pennsylvania courts. The lawsuit must relate to the activity being relied on. A single isolated act is enough if it fits one of the categories; the statute does not require ongoing or permanent presence in the Commonwealth.
Transacting Business
The broadest trigger is transacting any business in Pennsylvania. The statute reads this expansively. It covers a series of similar acts carried out for profit, a single act done with the intent to start such a series, shipping goods into or through the Commonwealth, and operating any business or profession here whether or not a state license is required.1Pennsylvania General Assembly. Pennsylvania Code Title 42 – Section 5322 Owning, using, or possessing real property in Pennsylvania also counts. A separate provision reaches anyone who contracts to supply services or goods to someone in the Commonwealth, even if the contract was signed in another state.
Causing Harm Inside or Felt Inside Pennsylvania
Jurisdiction attaches when a defendant causes harm through wrongful conduct that occurs inside Pennsylvania. A separate category covers harm felt in Pennsylvania even when the wrongful act happened somewhere else.1Pennsylvania General Assembly. Pennsylvania Code Title 42 – Section 5322 That second category is what often brings an out-of-state manufacturer into a Pennsylvania courtroom when a defective product injures a resident at home.
Real Property, Insurance, Fiduciary Roles, Licenses, and Legal Violations
An interest in, use of, or possession of real estate anywhere in Pennsylvania is its own basis for jurisdiction, which pulls in out-of-state landlords, out-of-state owners facing boundary disputes, and out-of-state owners facing premises liability claims.
Contracting to insure any person, property, or risk located in Pennsylvania at the time of the contract creates jurisdiction, as does controlling or serving as an officer of an insurance company incorporated here. Accepting a fiduciary role under Pennsylvania authority (personal representative of a decedent, guardian, trustee, or corporate director) is another basis. So is applying for or exercising any Pennsylvania license, permit, or similar authorization. The final category reaches anyone who violates a Pennsylvania statute, ordinance, or court order.1Pennsylvania General Assembly. Pennsylvania Code Title 42 – Section 5322
The Constitutional Ceiling
Section 5322(b) goes further than the enumerated list. It extends jurisdiction “to the fullest extent allowed under the Constitution of the United States” and provides that jurisdiction “may be based on the most minimum contact with this Commonwealth allowed under the Constitution.”2Pennsylvania General Assembly. Pennsylvania Code Title 42 Chapter 53 – Section 5322 If the Constitution permits a Pennsylvania court to hear the case, the statute authorizes it. That makes the federal case law the real outer boundary, and that case law divides jurisdiction into two kinds.
Specific Jurisdiction
Specific jurisdiction applies when the lawsuit arises directly from the defendant’s contact with Pennsylvania. In International Shoe Co. v. Washington, the U.S. Supreme Court held that jurisdiction over a non-resident is constitutional when the defendant has “minimum contacts” with the state and the suit would not offend “traditional notions of fair play and substantial justice.”3Justia US Supreme Court. International Shoe Co. v. Washington, 326 U.S. 310 Courts look at whether the defendant deliberately directed activity at Pennsylvania residents and whether being sued here was reasonably foreseeable. A connection that is accidental, or that results from someone else’s unilateral conduct, is not enough.
General Jurisdiction
General jurisdiction lets a court hear any claim against the defendant, even one unrelated to the defendant’s Pennsylvania activities. The threshold is much higher. In Daimler AG v. Bauman, the Supreme Court held that general jurisdiction over a corporation exists only where the corporation is “essentially at home,” which for most companies means the state of incorporation or the principal place of business.4Justia US Supreme Court. Daimler AG v. Bauman, 571 U.S. 117 For an individual, the equivalent is their home state. A company with a satellite office and a handful of employees in Pennsylvania is almost certainly not “at home” here for general jurisdiction purposes, even if those contacts feel substantial.
Websites and Online Sales
Operating a website that Pennsylvania residents can reach does not, by itself, create jurisdiction. The leading framework is the sliding scale from Zippo Manufacturing Co. v. Zippo Dot Com, Inc., a federal decision out of Pennsylvania.5Justia Law. Zippo Mfg. Co. v. Zippo Dot Com, Inc., 952 F. Supp. 1119 A business that enters into contracts with Pennsylvania residents online and repeatedly transmits files or data is doing business here, and jurisdiction is proper. A passive website that only posts information, with no transactions or meaningful interaction, does not create jurisdiction no matter how many Pennsylvania visitors it attracts. Interactive sites in between are judged by how much actual commercial exchange occurs and whether it targets Pennsylvania specifically. A company that ships products to hundreds of Pennsylvania customers through its site is in; a company whose only Pennsylvania connection is appearing in local search results is not.
Challenging a Pennsylvania Court’s Jurisdiction
Being named in a Pennsylvania lawsuit does not mean an out-of-state defendant is stuck litigating here. The defense exists, but it has to be raised correctly and early.
Preliminary Objections
The primary tool is a preliminary objection under Pennsylvania Rule of Civil Procedure 1028(a)(1), which allows a defendant to object based on “lack of jurisdiction over the subject matter of the action or the person of the defendant, improper venue or improper form or service.”6Pennsylvania Code and Bulletin. 231 Pa. Code Rule 1028 – Preliminary Objections These objections are filed before answering the complaint. Once raised, the plaintiff bears the burden of proving that the court has jurisdiction over the defendant.
Waiver
This is where defendants most often lose the defense. Participating in the case without first raising the jurisdiction challenge treats the defense as waived. Simply appearing in court or filing claims is read as a waiver of defects in service, although Pennsylvania does allow a defendant to request a limited hearing to contest jurisdiction without that appearance counting as a waiver.7Unified Judicial System of Pennsylvania. Rule 302.1 and Amended Rule 314 A defendant who wants to fight jurisdiction has to do it first, not after engaging with the merits.
Forum Non Conveniens
Jurisdiction can exist and Pennsylvania can still be the wrong place to try the case. Under 42 Pa. C.S. § 5322(e), a court may stay or dismiss a case when “in the interest of substantial justice the matter should be heard in another forum.”8Unified Judicial System of Pennsylvania. Superior Court Opinion J-A01004-25 The defendant carries the burden, and courts give significant deference to the plaintiff’s choice of forum. To overcome that deference, the defendant must show an adequate alternative forum exists and that practical factors, like where the evidence sits, whether witnesses can be compelled, and the overall cost of trial, strongly favor hearing the case elsewhere. Pennsylvania courts cannot transfer a case to another state’s court system. If the motion is granted, the court dismisses the case and the plaintiff refiles elsewhere.
Serving an Out-of-State Defendant
Jurisdiction is only half the picture. The plaintiff still has to deliver the suit papers in a way the rules recognize. Pennsylvania Rule of Civil Procedure 404 governs service outside the Commonwealth and gives the plaintiff ninety days from filing to complete it. The rule authorizes four methods:9Pennsylvania Code and Bulletin. 231 Pa. Code Rule 404 – Service Outside the Commonwealth
- Personal delivery by a competent adult who is not the plaintiff, following the in-state procedures in Rule 402.
- Mail requiring a signed receipt from the defendant or an authorized agent, under Rule 403.
- Service under the rules of the state or country where the defendant is located.
- Service under an applicable international treaty.
Mail is the most common choice because it avoids hiring a process server in another state. Certified mail with return receipt requested satisfies Rule 403, and the signed receipt must be filed with the court as proof.10Pennsylvania Code and Bulletin. 231 Pa. Code Rule 403 – Service by Mail If the defendant refuses the mail, the plaintiff can resend by ordinary mail with the sender’s return address, and service is complete if the mail is not returned within fifteen days. If the first mailing comes back as unclaimed rather than refused, ordinary mail is not an option, and the plaintiff has to use another method.
Defendants Outside the United States
If the defendant is in another country that belongs to the Hague Service Convention of 1965, the treaty’s procedures are generally mandatory and override Pennsylvania’s domestic service rules. The plaintiff sends a formal request and the suit papers to the destination country’s designated Central Authority, which arranges service under local law.11Hague Conference on Private International Law. Convention on the Service Abroad of Judicial and Extrajudicial Documents The process is slow, often three to twelve months, and the paperwork requirements are strict. Some countries permit alternatives such as postal channels or consular service; others have formally objected to them, so each country’s declarations under the Convention have to be checked before a method is chosen. For defendants in non-member countries, Rule 404 still allows service under the foreign jurisdiction’s own laws or by letter rogatory.
