Minimum contacts

Minimum contacts is a foundational doctrine in United States constitutional law governing personal jurisdiction, requiring that an out-of-state defendant have sufficient connections with the forum state such that exercising jurisdiction over them does not violate the Due Process Clause of the Fourteenth Amendment.^[1] Originating from the Supreme Court's decision in International Shoe Co. v. Washington (1945), the doctrine holds that "due process requires only that in order to subject a defendant to a judgment in personam, if he be not present within the territory of the forum, he have certain minimum contacts with it such that the maintenance of the suit does not offend 'traditional notions of fair play and substantial justice.'"^[2] In that case, the Court found jurisdiction over a Delaware corporation in Washington state based on its employment of salesmen who conducted systematic solicitation activities there, generating significant commissions, even without a physical office or inventory in the state.^[2] The minimum contacts standard distinguishes between specific jurisdiction, which applies when the suit arises out of or relates to the defendant's contacts with the forum, and general jurisdiction, which permits suits on any claim if the defendant's affiliations with the forum are so continuous and systematic as to render them essentially at home there.^[1] For specific jurisdiction, the defendant must have purposefully availed itself of the privilege of conducting activities in the forum state, invoking its laws' benefits and protections, as emphasized in Burger King Corp. v. Rudzewicz (1985), where a Michigan franchisee's substantial contractual relationship with a Florida-based franchisor supported jurisdiction in Florida courts.^[1] General jurisdiction, by contrast, is typically limited to the defendant's place of incorporation or principal place of business, as clarified in Daimler AG v. Bauman (2014), which rejected expansive theories based on extensive sales or operations alone.^[1] Over time, the doctrine has evolved through cases addressing foreseeability, stream-of-commerce activities, and fairness considerations, including exceptions for foreign sovereigns under the Foreign Sovereign Immunities Act (FSIA), as clarified in CC/Devas (Mauritius) Ltd. v. Antrix Corp. Ltd. (2025), which held that minimum contacts are not required when an FSIA immunity exception applies.^[3] These principles continue to guide lower courts in balancing interstate commerce with due process protections.^[1]

Overview

Definition and Purpose

The minimum contacts doctrine refers to the constitutional requirement that a non-resident defendant must maintain purposeful affiliations with the forum state that are sufficient to justify the exercise of personal jurisdiction consistent with due process under the Fourteenth Amendment.^[1] This standard ensures that a defendant's connections to the state are deliberate and meaningful, rather than fortuitous or attenuated.^[4] The purpose of the minimum contacts requirement is to promote fairness by safeguarding defendants from the burdens of litigating in a remote or unrelated forum, thereby upholding traditional notions of fair play and substantial justice.^[4] It prevents arbitrary assertions of jurisdiction, such as those based solely on transient physical presence, and balances the forum state's sovereign interests against the defendant's liberty interests.^[1] At its core, the doctrine applies a test assessing whether the quality and nature of the defendant's contacts render the exercise of jurisdiction reasonable and just, such that maintaining the suit aligns with due process.^[4] This framework shifted from inflexible territorial boundaries to a more adaptable, case-by-case evaluation focused on the defendant's voluntary engagement with the forum.^[4] Within this doctrine, minimum contacts may underpin specific jurisdiction tied to the underlying claim or general jurisdiction arising from pervasive forum ties.^[1]

Constitutional Framework

The minimum contacts doctrine derives its constitutional foundation from the Due Process Clause of the Fourteenth Amendment, which applies to state courts and restricts their authority to exercise personal jurisdiction over nonresident defendants.^[5] This clause ensures that such jurisdiction does not violate fundamental principles of fairness by subjecting individuals to out-of-state litigation without sufficient ties to the forum.^[6] For federal courts, the Due Process Clause of the Fifth Amendment provides the analogous limitation, imposing similar constraints on jurisdiction over defendants.^[7] These due process provisions incorporate limits on state power to "hail" defendants into court, preventing arbitrary assertions of jurisdiction that could undermine interstate comity and individual liberty.^[1] The doctrine thereby protects nonresidents from being compelled to defend suits in distant forums lacking meaningful connections, aligning with broader constitutional aims of orderly judicial administration.^[8] In International Shoe Co. v. Washington (1945), the Supreme Court articulated the core standard, holding that jurisdiction is proper only if the defendant has "certain minimum contacts with [the forum state] such that the maintenance of the suit does not offend 'traditional notions of fair play and substantial justice.'"^[2] State long-arm statutes serve as the statutory mechanism to authorize personal jurisdiction, typically extending to the outermost limits permitted by the Constitution, with minimum contacts establishing the federal constitutional floor. These statutes enable states to reach nonresidents based on activities like transacting business or committing torts within the state, but their application remains bounded by due process requirements to ensure contacts are purposeful and jurisdiction is reasonable.^[1] In assessing jurisdiction, the plaintiff generally bears the initial burden of demonstrating that the defendant has established minimum contacts with the forum.^[9] Once this prima facie showing is made, the burden shifts to the defendant to challenge the exercise of jurisdiction by demonstrating that it would violate notions of fair play and substantial justice, considering factors such as the burden on the defendant, the forum state's interest in adjudicating the dispute, and the plaintiff's interest in obtaining relief.^[10] This allocation promotes efficiency while safeguarding constitutional protections.

Historical Evolution

Pre-Minimum Contacts Doctrines

Prior to the adoption of the minimum contacts standard, personal jurisdiction in the United States was governed by rigid territorial principles rooted in common law and the sovereignty of states. The seminal case of Pennoyer v. Neff (1878) established that a state court's jurisdiction was limited to persons or property physically present within its borders, requiring personal service of process on the defendant while in the state or attachment of property before the suit's commencement.^[11] This decision interpreted the Due Process Clause of the Fourteenth Amendment to mandate such territorial limits, invalidating judgments obtained through mere publication or extraterritorial service against nonresidents.^[12] Central to the Pennoyer framework was the power theory of jurisdiction, which posited that a court's authority derived solely from its physical power to compel the defendant's appearance or seize property (the res) within the forum state.^[12] Under this theory, states could exercise in personam jurisdiction only over individuals domiciled or personally served in the state, ensuring the tribunal's coercive reach. For property-based claims, in rem jurisdiction allowed adjudication of rights in property located within the state, binding the world to the judgment regarding that res, while quasi in rem jurisdiction extended to unrelated personal obligations but limited recovery to the value of the attached property.^[12] These distinctions permitted constructive notice, such as publication, for in rem actions but not for broader personal liability.^[13] The Pennoyer doctrines faced significant criticisms for their inflexibility in an era of growing interstate mobility and commerce. The strict requirement of physical presence or property attachment often allowed defendants to evade jurisdiction simply by absenting themselves from the forum state, frustrating plaintiffs' ability to seek redress for harms arising from out-of-state activities. Legal scholars and courts noted that this territorial rigidity relied on outdated fictions, such as implied consent from driving through a state, to accommodate modern travel, yet it still hindered justice in a mobile society where individuals and businesses frequently crossed state lines without establishing domicile or tangible ties.

Establishment and Key Early Cases

The doctrine of minimum contacts emerged as a response to the rigid territorial limitations on personal jurisdiction that had prevailed prior to the mid-20th century, shifting the focus from mere physical presence to the quality and nature of a defendant's connections with the forum state.^[1] A key precursor to this development was Hess v. Pawloski (1927), where the U.S. Supreme Court upheld a Massachusetts statute deeming nonresident motorists to have impliedly consented to personal jurisdiction by using the state's highways, thereby allowing service of process for accidents occurring within the state.^[14] This decision marked an early relaxation of strict territorial requirements by tying jurisdiction to voluntary activity within the forum, limited to claims arising from that activity.^[15] The foundational case establishing the minimum contacts standard was International Shoe Co. v. Washington (1945), in which the Supreme Court ruled that due process permits a state to exercise personal jurisdiction over an out-of-state defendant if it has certain minimum contacts with the forum such that the suit does not offend traditional notions of fair play and substantial justice. In that case, the Court found sufficient contacts where the defendant shoe company employed sales representatives and engaged in systematic solicitation of business within Washington, justifying jurisdiction in a suit to collect unemployment compensation taxes attributable to those activities.^[16] This test replaced the prior emphasis on physical presence with a more flexible inquiry into purposeful affiliations with the state.^[17] Subsequent decisions in the 1950s further refined and expanded the doctrine. In McGee v. International Life Insurance Co. (1957), the Court held that a single insurance contract, mailed to and accepted by a California resident, provided the necessary minimum contacts for California courts to exercise jurisdiction over an out-of-state insurer in a suit for benefits under that policy.^[18] The decision underscored that even isolated but purposeful contacts could support jurisdiction when the claim arose directly from those contacts, emphasizing the defendant's deliberate engagement with the forum's residents.^[19] However, Hanson v. Denckla (1958) imposed important limits on the doctrine's reach, ruling that a Delaware trust company's contacts with Florida were insufficient for Florida courts to exercise jurisdiction over it in a dispute concerning the trust's validity. The Court clarified that jurisdiction requires the defendant to have purposefully availed itself of the privilege of conducting activities within the forum state, rather than unilateral actions by the plaintiff drawing the defendant in.^[20] This introduction of "purposeful availment" as a core element ensured that minimum contacts must reflect the defendant's intentional invocation of the benefits and protections of the forum's laws.^[21]

Types of Personal Jurisdiction

Specific Jurisdiction

Specific jurisdiction permits a court to exercise personal jurisdiction over a nonresident defendant only when the plaintiff's claim arises out of or relates to the defendant's contacts with the forum state, ensuring that the defendant's deliberate actions in the forum form the basis for the suit.^[22] This claim-specific approach limits jurisdiction to disputes tied to the defendant's forum-related conduct, distinguishing it from general jurisdiction, which permits suits on unrelated claims based on broader affiliations with the forum. Central to specific jurisdiction is the requirement of purposeful availment, under which the defendant must intentionally direct activities toward the forum state, thereby creating a substantial connection and foreseeably hailing itself into the forum's courts.^[22] In Burger King Corp. v. Rudzewicz (1985), the U.S. Supreme Court upheld jurisdiction over a Michigan franchisee sued in Florida for breach of a franchise agreement, emphasizing that the defendant had purposefully availed himself of Florida law by negotiating the contract, accepting its terms, and benefiting from the forum's protections, even without physical presence there.^[22] This test focuses on the quality and nature of the defendant's contacts rather than their quantity, requiring deliberate engagement that invokes the forum's benefits and burdens.^[22] The nexus between the claim and the contacts is evaluated through the "arises out of or relates to" standard, where "arises out of" demands a direct causal link, but "relates to" allows for a looser affiliation as long as there is an "affiliation between the forum and the underlying controversy."^[23] The Supreme Court expanded this in Ford Motor Co. v. Montana Eighth Judicial District Court (2021), holding that Montana and Minnesota courts could exercise jurisdiction over Ford in product liability suits involving accidents with Ford vehicles, despite the cars not being sold in those states, because Ford's extensive advertising, sales, and service networks in the forums created a substantial relationship to the claims without requiring the specific vehicle to originate there.^[23] This broader interpretation rejects a strict but-for causation requirement, permitting jurisdiction when the defendant's in-forum activities bear a meaningful tie to the litigation.^[23] Once minimum contacts are established, the exercise of specific jurisdiction must also satisfy traditional notions of fair play and substantial justice, assessed through several factors including the burden on the defendant to defend in the forum, the plaintiff's interest in obtaining convenient and effective relief, the forum state's interest in adjudicating the dispute, the interstate judicial system's interest in efficient resolution of the controversy, and the states' shared interest in furthering fundamental substantive social policies. These considerations, originating from International Shoe Co. v. Washington (1945), ensure that jurisdiction is reasonable and not unduly onerous, though a heavy burden on the defendant alone rarely defeats jurisdiction if other factors weigh in favor. Illustrative examples include contract disputes where performance or enforcement is linked to the forum, such as a nonresident entering a business agreement governed by forum law and directed at forum residents, as in Burger King.^[22] In tort cases, jurisdiction arises when the defendant purposefully directs harmful conduct toward the forum, like broadcasting defamatory statements into the state or committing an intentional tort with effects felt there, provided the claim relates to those directed activities.^[22]

General Jurisdiction

General jurisdiction permits a state court to exercise personal jurisdiction over a nonresident defendant with respect to any and all claims, provided the defendant's affiliations with the forum state are so continuous and systematic as to render the defendant essentially "at home" there.^[24] This form of jurisdiction, distinct from specific jurisdiction which ties claims to the defendant's forum-related activities, allows suits on causes of action entirely unrelated to the defendant's contacts with the state.^[4] The doctrine ensures that defendants are not haled into court in forums where they lack substantial ties, consistent with due process under the Fourteenth Amendment.^[4] The foundational principle traces to International Shoe Co. v. Washington (1945), where the Supreme Court rejected rigid territorial limits on jurisdiction in favor of a flexible minimum contacts analysis, emphasizing that jurisdiction must not offend "traditional notions of fair play and substantial justice."^[4] Building on this, Goodyear Dunlop Tires Operations, S.A. v. Brown (2011) clarified that for corporations, general jurisdiction requires contacts of a nature that the entity is fairly regarded as at home, beyond mere continuous business operations or attenuated affiliations like isolated sales.^[24] Mere doing business in a state, without more, is insufficient to establish such a presence.^[24] The paradigm forums for general jurisdiction over a corporation are its state of incorporation and its principal place of business, as affirmed in Daimler AG v. Bauman (2014).^[25] In Daimler, the Court held that a German automaker was not subject to general jurisdiction in California despite its American subsidiary's substantial sales there, emphasizing that only "exceptional cases" could justify jurisdiction elsewhere, such as when a corporation's operations in the forum are so substantial and of a sort that approximate physical presence throughout the forum's territory.^[25] These exceptional circumstances, like pervasive control over a subsidiary during extraordinary events (e.g., wartime relocation), are narrowly construed and rarely found.^[25] For individuals, general jurisdiction typically attaches at their domicile.^[25] The Daimler decision significantly raised the threshold for asserting general jurisdiction, curtailing forum-shopping by plaintiffs and limiting suits against corporations to their core operational homes, thereby promoting predictability in interstate commerce.^[25]

Traditional Bases for Minimum Contacts

Physical Presence

The traditional rule of personal jurisdiction based on physical presence, often referred to as "tag" or "transient" jurisdiction, holds that a court may exercise jurisdiction over a nonresident defendant if they are personally served with process while physically present within the forum state, regardless of the duration or purpose of that presence.^[26] This doctrine traces its roots to common law principles predating the adoption of the Fourteenth Amendment's Due Process Clause and was reaffirmed by the U.S. Supreme Court in Burnham v. Superior Court (1990), where the Court upheld jurisdiction over a nonresident husband served during a brief visit to California for reasons unrelated to the divorce proceedings.^[26] In Burnham, a plurality of the Court emphasized that such service constitutes a presumptively reasonable exercise of state power, as it aligns with historical territorial sovereignty and avoids the need for a separate "minimum contacts" analysis under International Shoe Co. v. Washington (1945).^[4] Under this rule, even a brief and purposeful entry into the forum state suffices to establish jurisdiction if service occurs during that time, without requiring evidence of ongoing or substantial ties to the state.^[27] The rationale is that physical presence invokes the state's territorial authority, providing notice and an opportunity to be heard that comports with due process.^[26] However, limitations exist: the presence must be voluntary and not obtained through fraud, trickery, or enticement, as courts will quash service procured by such means to prevent abuse of process.^[28] This basis applies primarily to individuals, as corporations lack a literal physical presence; for corporate defendants, jurisdiction typically requires service on an authorized agent or officer while in the state, though this often overlaps with "doing business" standards rather than pure transient presence.^[29] Physical presence jurisdiction often bypasses the "minimum contacts" framework of long-arm statutes, which extend authority over absent defendants based on purposeful affiliations with the forum.^[30] If valid in-state service is effected, the court need not analyze whether the claim arises from forum-related activities, as presence alone satisfies due process for general jurisdiction.^[26] In modern application, the doctrine remains viable despite increased mobility and technology, continuing to support jurisdiction in cases of temporary visits, such as business trips or family events.^[31] Nonetheless, it has faced criticism for its potential arbitrariness, as it can subject defendants to suit in distant forums based on fortuitous or fleeting presence, raising fairness concerns in an era of global travel.^[32] Consent to personal jurisdiction serves as an independent basis for satisfying the minimum contacts requirement under the Due Process Clause, allowing parties to voluntarily submit to a forum's authority and thereby waive challenges based on insufficient contacts. Explicit consent most commonly arises through forum selection clauses in contracts, which designate a specific court or jurisdiction for resolving disputes. In M/S Bremen v. Zapata Off-Shore Co., the U.S. Supreme Court established that such clauses are presumptively valid and enforceable unless they are unreasonable, unjust, or deprive a party of its day in court, emphasizing the parties' freedom to contractually allocate litigation risks.^[33] This principle applies broadly to commercial agreements, provided the clause was negotiated at arm's length and does not contravene public policy.^[33] Implied consent occurs when a party's actions or statutory compliance indicate agreement to jurisdiction without an overt declaration. A classic example is the appointment of an agent for service of process, as upheld in Hess v. Pawloski, where the Supreme Court ruled that non-resident motorists impliedly consent to a state's jurisdiction for accidents occurring on its highways by operating a vehicle there and designating a state official as their agent under applicable statutes.^[14] Similarly, contractual provisions authorizing service on an agent can imply consent, even in form contracts, as long as the agency relationship is validly established.^[34] Waiver of personal jurisdiction defenses can also establish jurisdiction through inaction, distinct from affirmative consent. Under Federal Rule of Civil Procedure 12(h)(1), a defendant waives objections to personal jurisdiction by failing to raise them in a pre-answer motion or responsive pleading, thereby submitting to the court's authority.^[35] This procedural waiver promotes efficiency by requiring timely challenges and applies in both federal and state courts incorporating similar rules. However, consent to jurisdiction has limits to ensure compliance with due process. It must be knowing and voluntary; coerced or uninformed submissions, such as those buried in adhesion contracts without meaningful notice, may not suffice.^[34] Moreover, while consent can establish specific jurisdiction tied to the dispute, it cannot independently confer general jurisdiction over unrelated claims absent minimum contacts, though statutory schemes may bridge this gap.^[25] In the corporate context, many states' "doing business" or registration statutes imply consent to jurisdiction by requiring foreign corporations to appoint a registered agent as a condition of transacting business. These provisions faced challenges following Daimler AG v. Bauman, where the Supreme Court expressed skepticism about whether mere registration alone equates to true consent for general jurisdiction, potentially rendering such statutes unconstitutional if they impose unlimited liability without substantial ties.^[25] Yet, in Mallory v. Norfolk Southern Railway Co., the Court upheld Pennsylvania's registration statute, ruling that explicit consent to general personal jurisdiction as a registration prerequisite does not violate due process, provided the corporation knowingly complies.^[36] This decision reaffirms consent-by-registration as a viable basis, though its application varies by state and may require clear statutory language to avoid due process scrutiny.^[37]

Activity-Based Bases

Commercial Activities

In the context of specific personal jurisdiction, commercial activities establish minimum contacts when a nonresident defendant purposefully avails itself of the forum state's market by deliberately engaging in business conduct that creates substantial connections with the forum. This purposeful availment requires more than random or attenuated contacts; instead, it involves intentional acts that invoke the benefits and protections of the forum's laws, ensuring the defendant could reasonably anticipate being haled into court there for related disputes.^[38] A seminal example is entering into contracts with forum residents or entities, particularly when negotiations, execution, or performance occur in or are directed toward the state. In Burger King Corp. v. Rudzewicz (1985), the Supreme Court upheld jurisdiction in Florida over a Michigan franchisee who breached a franchise agreement with Burger King's Florida headquarters, finding sufficient contacts from the defendant's active participation in extended negotiations with the Florida office, agreement to a Florida choice-of-law clause, and transmission of payments to Florida over an 18-month period. The Court applied a multi-factor test emphasizing the quality of the relationship, including prior negotiations and contemplated future consequences, the contract's terms, and the parties' course of dealings, rather than relying solely on the contract's existence.^[22] Similar principles apply to directing sales into the forum or maintaining offices there for commercial purposes tied to the claim, as these acts demonstrate deliberate exploitation of the forum's economic opportunities.^[38] Courts further assess commercial contacts by considering factors such as the volume and value of transactions, alongside the foreseeability of consequences or harm arising in the forum from the defendant's conduct. For instance, targeted advertising or in-state performance of contractual duties can support jurisdiction for breach-of-contract claims, as these activities reflect intentional engagement with the forum's market. However, the analysis prioritizes the nature and relatedness of the contacts to the suit, ensuring they are not merely incidental.^[22] Regarding corporate defendants, minimum contacts through commercial activities may be imputed from agents or subsidiaries only if an alter ego relationship or genuine agency exists, meaning the subsidiary functions as the parent's mere instrumentality without separate identity. The Supreme Court in Daimler AG v. Bauman (2014) rejected automatic imputation of a U.S. subsidiary's contacts to its foreign parent for general jurisdiction absent exceptional circumstances like alter ego status. This limitation confines jurisdiction to claims arising from the defendant's own or attributable suit-related commercial acts in the forum.^[25]

Non-Commercial and Internet Activities

In the context of non-commercial activities, courts assess minimum contacts for personal jurisdiction primarily through intentional torts, such as defamation, where a defendant's actions are expressly aimed at the forum state, causing foreseeable harm there. The seminal case Calder v. Jones (465 U.S. 783, 1984) established the "effects test," holding that jurisdiction is proper when a defendant commits an intentional act, expressly aimed at the forum, that causes harm within it. In Calder, Florida-based journalists for the National Enquirer wrote a libelous article targeting a California actress, with substantial circulation in California, leading the Supreme Court to find sufficient contacts because the defendants "must reasonably anticipate being haled into court there" for the foreseeable injury.^[39] This test applies to non-commercial torts like defamation, where the defendant's purposeful direction at the forum—rather than mere foreseeability of harm—satisfies due process requirements under the Fourteenth Amendment.^[1] For internet activities, courts evaluate minimum contacts using the Zippo sliding scale, introduced in Zippo Manufacturing Co. v. Zippo Dot Com, Inc. (952 F. Supp. 1119, W.D. Pa. 1997), which categorizes websites based on interactivity to determine purposeful availment. At one end, passive websites that merely post information available to anyone do not establish jurisdiction, as they lack deliberate targeting of the forum.^[40] Interactive websites fall in the middle, where jurisdiction depends on the level of exchange and commercial nature, though non-commercial interactions may suffice if they involve repeated contacts with forum residents. Active websites, involving knowing transmission of files or contracts with forum users, clearly support jurisdiction. For instance, a defendant operating an interactive site that allows forum residents to engage in virtual transactions or forums may create minimum contacts if those activities relate to the claim.^[40] Post-Walden v. Fiore (571 U.S. 277, 2014), purposeful direction in online contexts requires defendant-created contacts with the forum state itself, not just harm to forum residents from out-of-state actions. In Walden, the Supreme Court rejected jurisdiction in Nevada over a Georgia defendant's seizure of funds from Nevada plaintiffs, emphasizing that "the relationship must arise out of contacts with the forum State," not the plaintiff's connections.^[41] Applied online, this means jurisdiction arises from foreseeable use by forum residents only if the defendant targets them, such as through geotargeted content or posts expressly aimed at a forum audience, like defamatory statements on social media directed at individuals known to reside there.^[42] For example, an out-of-state poster defaming a forum resident by tagging them in content or referencing local events may satisfy the effects test if the harm is intentionally inflicted within the state.^[1] Challenges in asserting jurisdiction over internet activities stem from the medium's anonymity and borderless nature, which often obscure targeting and limit minimum contacts without clear evidence of purposeful direction. Anonymity tools, like pseudonymous accounts, complicate identifying defendants and proving intent, while the internet's global reach makes it difficult to establish that passive or incidental access by forum users constitutes deliberate availment.^[43] Courts thus require plaintiffs to show more than mere accessibility, such as targeted advertising or user-specific interactions, to overcome these hurdles and ensure fairness under due process.^[44]

Property-Based Bases

Tangible Property

In the context of personal jurisdiction, the ownership or use of tangible property, such as real estate or chattels, within a forum state can establish minimum contacts by creating systematic and continuous affiliations with the state. For instance, a defendant's ownership of land in the forum may support specific jurisdiction over disputes directly related to that property, like title challenges or boundary issues, as the property's presence implies purposeful engagement with the state's legal framework for realty matters.^[45]^[46] Quasi in rem jurisdiction historically allowed courts to assert authority over a defendant by attaching tangible property in the forum, even for claims unrelated to the property, with recovery limited to the property's value. However, the U.S. Supreme Court's decision in Shaffer v. Heitner (1977) fundamentally limited this approach by extending the minimum contacts requirement from International Shoe Co. v. Washington (1945) to all property-based assertions of jurisdiction, including tangible assets. Under Shaffer, attachment of chattels or realty alone no longer suffices; the defendant must have sufficient purposeful contacts with the forum to satisfy due process, ensuring the exercise of jurisdiction is fair and reasonable.^[47]^[4] An illustrative example involves the seizure of a nonresident defendant's vehicle or goods located in the forum state to secure a debt, where jurisdiction may be upheld if the defendant's prior activities, such as conducting business or delivering the chattel there, demonstrate availment of the forum's benefits.^[46] Despite these possibilities, mere ownership of tangible property is insufficient without a purposeful connection to the forum or relatedness to the suit, as isolated or fortuitous presence does not meet the constitutional threshold.^[47] Following Shaffer, quasi in rem jurisdiction based on tangible property has largely declined, supplanted by activity-based analyses that prioritize the defendant's deliberate interactions with the forum over mere territorial presence of assets. This shift reflects a broader emphasis on fairness in due process, rendering property attachments a secondary or supportive factor rather than an independent basis for jurisdiction.^[48]

Intangible Property and In Rem Jurisdiction

In the context of minimum contacts for personal jurisdiction, intangible property such as shares of stock, debts, or intellectual property rights may serve as a basis for jurisdiction only if the defendant has purposefully directed activities toward the forum state, establishing sufficient ties beyond mere presence of the asset.^[49] In Shaffer v. Heitner (1977), the U.S. Supreme Court addressed this issue in a shareholder derivative suit where Delaware courts sequestered stock certificates and other intangible interests of non-resident defendants solely because the shares were deemed sited in Delaware due to the corporation's incorporation there.^[49] The Court invalidated this sequestration under the Due Process Clause, holding that the fictional "situs" of intangibles cannot substitute for actual minimum contacts, as such jurisdiction would offend traditional notions of fair play and substantial justice without the defendant's purposeful availment of the forum.^[49] In rem jurisdiction traditionally allows a court to adjudicate claims directly against the property itself, binding the world as to interests in that res, rather than against specific persons.^[50] Classic examples include admiralty proceedings against a vessel located in the forum's territorial waters or probate actions determining rights in estate assets situated within the state.^[49] Under pre-Shaffer doctrine, the physical or deemed presence of the property within the forum sufficed for jurisdiction, as articulated in Pennoyer v. Neff (1878), without requiring personal contacts by the owner. The Shaffer decision fundamentally altered this framework by subjecting all forms of in rem and quasi in rem jurisdiction to the minimum contacts analysis established in International Shoe Co. v. Washington (1945).^[49] The Court reasoned that any assertion of state-court jurisdiction, even over property, must evaluate whether the defendant's contacts with the forum—factored with the burden on the defendant, the forum's interest in adjudication, and other fairness considerations—render the exercise of jurisdiction reasonable.^[49] Thus, while the property's location may contribute to the contacts calculus, it alone cannot justify jurisdiction if the underlying dispute is unrelated to the defendant's purposeful engagement with the forum.^[49] Post-Shaffer, courts apply this unified test to intangible property disputes, requiring evidence of the defendant's deliberate connection to the forum for the asset's situs to support jurisdiction. For instance, jurisdiction over a debt obligation might be proper if the creditor-defendant actively sought to enforce or collect it within the forum state, creating affiliating circumstances.^[51] Similarly, for intellectual property rights like patents or trademarks registered in the forum, jurisdiction depends on the defendant's purposeful exploitation or infringement activities directed there, rather than passive registration alone.^[52] In pure in rem actions closely tied to the property, such as foreclosure proceedings on liens encumbering forum-sited real estate or quiet title disputes over ownership interests, the property's location often supplies the necessary minimum contacts, as the litigation inherently relates to the res and implicates the forum's sovereign interest in resolving property conflicts within its borders.^[49] However, if the action seeks to affect the defendant's broader personal liability beyond the property's value—as in quasi in rem cases—the contacts must independently satisfy due process to avoid exposing non-resident defendants to unfair surprise.^[49] This approach ensures that intangible and in rem bases align with modern due process standards, prioritizing the quality of the defendant's relationship to the forum over archaic notions of territorial power.^[53]

Modern Developments and Exceptions

Stream of Commerce Doctrine

The stream of commerce doctrine provides a framework for establishing specific personal jurisdiction over nonresident defendants in product liability cases when their products foreseeably enter the forum state through commercial channels. Originating in the U.S. Supreme Court's decision in World-Wide Volkswagen Corp. v. Woodson, the doctrine recognizes that as interstate commerce expands, nonresidents may be subject to jurisdiction if they place products into the stream of commerce with the expectation that they will be purchased by consumers in the forum state. However, the Court clarified that mere foreseeability of a product's entry into the forum—such as an Audi purchased in New York accidentally reaching Oklahoma—is insufficient; instead, the defendant must purposefully avail itself of the forum's market to invoke the benefits and protections of its laws.^[54] The doctrine's contours became more contested in Asahi Metal Industry Co. v. Superior Court, where a Japanese valve manufacturer was sued in California after its components reached the state via a Taiwanese tire maker. The Court issued a fractured ruling with no majority opinion: Justice O'Connor's plurality (joined by three justices) held that placing a product into the stream of commerce, even with awareness that it might reach the forum, requires "additional conduct" indicating an intent to serve that specific market, such as designing products for the forum or establishing channels for service there. In contrast, Justice Brennan's concurrence (also joined by three justices) advocated a broader view, asserting that jurisdiction is proper whenever a defendant is aware its product enters the stream leading to the forum, as this constitutes purposeful availment. Justice Stevens, in a separate opinion, noted the doctrine's viability but emphasized fairness considerations, ultimately finding the burden on the foreign defendant excessive. This split left lower courts divided on whether "plus" factors beyond awareness are mandatory.^[55] Subsequent cases further refined the doctrine's requirements. In J. McIntyre Machinery, Ltd. v. Nicastro, a British manufacturer faced suit in New Jersey after its machine injured a worker there, despite no direct sales or targeting of the state—only attendance at national trade shows and a U.S. distributor. Justice Kennedy's plurality opinion (joined by three justices) rejected jurisdiction, holding that national distribution alone does not suffice; the defendant must engage in forum-specific activities to purposefully avail itself of the forum's laws, as the stream of commerce cannot displace the need for targeted contacts. Justice Ginsburg's concurrence (also three justices) would have upheld jurisdiction under a stream-of-commerce-plus approach, criticizing the plurality for narrowing Asahi's foreseeability standard, but agreed on the outcome due to the defendant's minimal ties. Without a majority test, the decision reinforced that generalized national presence fails the minimum contacts analysis.^[56] The Supreme Court revisited and broadened the doctrine in Ford Motor Co. v. Montana Eighth Judicial District Court, addressing consolidated cases where Ford was sued in Montana and Minnesota for defective vehicles involved in accidents, despite the specific cars being sold out-of-state. Unanimously, the Court held that Ford's extensive, purposeful contacts—including marketing campaigns, dealer networks, and widespread sales of similar models in the forums—supported jurisdiction, as the claims "arose out of or related to" those activities even without a direct causal link to the exact vehicle. This revived a more inclusive view of the doctrine, emphasizing that defendants who systematically serve the forum's market through advertising and distribution cannot evade accountability in product liability suits simply because the injury stems from an earlier-sold item. The ruling clarified that relatedness requires an affiliation between the forum contacts and the claim, but not strict causation, aligning with the doctrine's focus on fairness and foreseeability.^[57] In practice, the doctrine applies where manufacturers or distributors engage in targeted actions that direct products toward the forum, such as establishing authorized dealer networks or conducting state-specific advertising. For instance, courts have upheld jurisdiction over foreign automakers with local dealerships that service and sell vehicles, as these create ongoing commercial ties and expectations of liability for defects. Similarly, online or promotional efforts aimed at the forum's consumers—beyond passive website availability—can constitute purposeful availment, ensuring defendants who profit from the market bear the burdens of defending there.^[57]

Foreign Sovereigns and FSIA

The Foreign Sovereign Immunities Act (FSIA) of 1976 establishes a comprehensive framework for granting presumptive immunity to foreign states and their agencies or instrumentalities from the jurisdiction of U.S. courts, codifying the restrictive theory of sovereign immunity that distinguishes between a state's public acts (jure imperii) and private, commercial acts (jure gestionis). Under the FSIA, codified at 28 U.S.C. §§ 1602–1611, foreign sovereigns are immune unless a statutory exception applies, and these exceptions generally supplant the traditional due process requirements of minimum contacts for establishing personal jurisdiction over such defendants. For instance, the commercial activity exception in 28 U.S.C. § 1605(a)(2) permits jurisdiction in any case based upon commercial activity carried on in the United States by the foreign state, or upon an act performed in the United States in connection with such activity, or upon an act outside the territory of the United States in connection with a commercial activity of the foreign state elsewhere that causes a direct effect in the United States, thereby allowing suits without the need to prove suit-related contacts under the Fifth Amendment.^[58] Prior to 2025, federal courts debated whether the FSIA's exceptions incorporated a separate minimum contacts analysis derived from International Shoe Co. v. Washington, particularly in cases involving enforcement of arbitration awards against foreign states.^[59] Some circuits, such as the Ninth, required plaintiffs to demonstrate minimum contacts in addition to satisfying an FSIA exception, while others, like the D.C. Circuit, held that an exception alone sufficed for jurisdiction, creating a circuit split that complicated litigation against sovereign defendants.^[60] In a landmark unanimous decision on June 5, 2025, the U.S. Supreme Court resolved this debate in CC/Devas (Mauritius) Ltd. v. Antrix Corp. Ltd., holding that the FSIA does not impose a freestanding minimum contacts requirement for personal jurisdiction when a statutory exception applies.^[61] The case arose from a contract dispute between Devas, a Mauritius-based company, and Antrix, an Indian state-owned entity, where Devas sought to enforce an international arbitration award in U.S. courts under the commercial activity exception after India's Supreme Court annulled the award.^[59] The Court, in an opinion authored by Justice Alito, emphasized that the FSIA provides the sole basis for obtaining jurisdiction over a foreign state in U.S. courts, and satisfying an exception under § 1605(a) is sufficient without additional due process scrutiny, as the Act balances foreign policy interests with access to justice.^[62] This ruling has significant implications for litigation involving foreign sovereigns, easing the path for plaintiffs to establish jurisdiction in U.S. courts when immunity is waived through an FSIA exception, particularly in commercial and arbitration enforcement contexts, though it applies exclusively to foreign state defendants and not private parties.^[63] By clarifying that minimum contacts are not required, the decision reduces barriers for U.S.-based enforcement of foreign judgments and awards against sovereigns, potentially increasing such filings while preserving the FSIA's role in immunizing non-commercial sovereign acts.^[60] Beyond commercial activities, other FSIA exceptions further bypass traditional minimum contacts analysis, such as the expropriation exception under 28 U.S.C. § 1605(a)(3), which allows jurisdiction over claims for rights in property taken in violation of international law if the property is in the United States or the claim is one for money damages against a foreign state for takings occurring in the United States.^[58] Similarly, the terrorism exception, added by the Antiterrorism and Effective Death Penalty Act of 1996 and expanded in subsequent legislation, permits suits for personal injury or death caused by acts of torture, extrajudicial killing, aircraft sabotage, or hostage-taking sponsored by designated state sponsors of terrorism, without requiring minimum contacts proof, provided the entire claim arises out of such acts. These provisions underscore the FSIA's tailored approach to sovereign immunity, prioritizing specific policy goals like protecting property rights and combating state-sponsored terrorism over general jurisdictional thresholds.^[64]
