New York Personal Jurisdiction

Start with the defendant and claim

Personal jurisdiction asks whether a New York court may bind a particular defendant. Analyze each defendant separately and identify the claim asserted. A court may have subject-matter jurisdiction over a dispute but lack personal jurisdiction over a nonresident. Valid service of process is another distinct requirement; establishing a jurisdictional basis does not itself prove service was proper.

New York's Civil Practice Law and Rules address general jurisdiction in CPLR 301 and jurisdiction over non-domiciliaries in CPLR 302. The long-arm statute applies only to claims arising from one of its enumerated acts. A court must also satisfy due process.

General jurisdiction under CPLR 301

CPLR 301 preserves jurisdiction New York courts could historically exercise. For individuals, domicile is a central general-jurisdiction basis. For a corporation, the constitutional general-jurisdiction analysis ordinarily asks whether it is essentially at home, commonly at its place of incorporation or principal place of business, with exceptional cases possible.

Regular sales, employees or business activity in New York do not automatically establish general jurisdiction over a corporation. Analyze the defendant's overall relationship to the state and the applicable constitutional standard. Do not treat doing business as a shorthand without identifying the legal test.

Specific jurisdiction under CPLR 302

CPLR 302(a) authorizes jurisdiction over a non-domiciliary for a cause of action arising from specified New York-related conduct. The principal grounds include transacting business in New York or contracting to supply goods or services here; committing a tortious act in the state; committing certain out-of-state torts causing injury in New York, subject to statutory conditions; and owning, using or possessing New York real property.

The phrase ‘arising from’ requires a relationship between the claim and the enumerated act. A nonresident's unrelated New York transaction does not create jurisdiction for every claim. A contract dispute may turn on negotiations, performance, contemplated consequences and the parties' actual course of dealing. A tort claim may turn on where the conduct occurred and where the injury was sustained.

For an out-of-state tort causing in-state injury, CPLR 302(a)(3) includes additional requirements, such as regular business or substantial revenue connected to New York, or an expectation or reasonable anticipation that the conduct would have consequences in New York together with substantial revenue from interstate or international commerce. Read the statutory alternatives carefully rather than treating every New York injury as sufficient.

Due process

Even when CPLR 302 applies, due process requires adequate purposeful contacts and a fair exercise of jurisdiction. The defendant must have deliberately engaged with New York; the plaintiff's unilateral activity is not enough. Evaluate the relationship among the defendant, forum and claim, then consider whether exercising jurisdiction is reasonable.

An online sale to a New York resident does not answer the issue by itself. Consider whether the defendant targeted New York, the nature of the transaction, where performance occurred and whether the claim concerns that conduct. A seller that deliberately serves the New York market presents a different case from a one-time sale that reaches the state through another person's unilateral move.

Consent, appearance and service

A defendant may consent to jurisdiction, including through a valid forum-selection clause or voluntary appearance. A defendant may waive certain objections by failing to raise them timely under New York procedure. Analyze the method and timing of the appearance rather than assuming jurisdiction is always contested.

Service rules govern how the defendant receives the summons and complaint. A valid jurisdictional basis does not cure defective service, and proper service does not create a missing statutory or constitutional basis. Keep the issues separate in an essay.

NYLE analysis checklist

1. Identify each defendant, domicile and claim.
2. Test CPLR 301 or another traditional basis.
3. For a non-domiciliary, identify the precise CPLR 302 subsection and act.
4. Connect the claim to that act and establish any extra statutory conditions.
5. Apply purposeful-contact and fairness requirements.
6. Analyze consent, waiver and service independently.

A strong answer names the statutory ground and ties it to a specific fact. ‘The defendant does business in New York’ is incomplete if the claim does not arise from that activity or the statute's conditions are not met.

Keep statutory jurisdiction and due process separate

New York long-arm jurisdiction requires statutory authority and constitutional due process. A defendant's conduct can satisfy one inquiry but fail the other. Start with the exact CPLR 302 subsection and the defendant's act. Then ask whether the claim arises from the required connection and whether exercising jurisdiction satisfies due process. Proper service is yet another question.

For CPLR 302(a)(1), the analysis concerns transacting business in New York and a claim arising from that transaction. A single purposeful transaction may suffice in an appropriate case; the statute does not require a permanent New York office. But a New York plaintiff or an out-of-state contract with no meaningful New York activity does not automatically establish jurisdiction.

Connect the claim to the transaction

Suppose a New York company orders custom software from a Massachusetts developer. The developer negotiates remotely, travels to New York for design meetings, receives New York-directed requirements and performs continuing support under the agreement. A claim that the delivered software failed those requirements has a direct connection to the transaction and its forum activity. A dispute about an unrelated personal loan may not.

The inquiry is fact-specific. Consider negotiations, contract terms, contemplated consequences, performance and the parties' course of dealing. A contract with a New York resident alone is not dispositive. Identify what the defendant deliberately did in or toward New York and connect that act to the claim.

Analyze other CPLR 302 grounds by their elements

CPLR 302 includes additional statutory grounds, such as committing a tortious act within New York, committing an out-of-state tort that causes in-state injury under specified conditions, owning or using New York real property, or certain acts connected to matrimonial claims. Each subsection has its own elements and exceptions. Do not cite “long-arm jurisdiction” generically when a fact pattern clearly raises one provision.

For an out-of-state tort causing New York injury, identify the statutory conditions beyond the injury itself. The statute includes requirements relating to additional conduct or expected consequences and, in some circumstances, a substantial-revenue condition. The exact text controls. A plaintiff's New York residence or an injury felt economically in New York does not automatically establish every element.

For a tort committed in New York, ask who acted and where the conduct occurred. A defendant who personally enters New York and commits the alleged tort presents a different statutory question from a defendant whose product or statement reaches the state through another party. After finding a statutory ground, still analyze due process.

General jurisdiction and corporate presence

CPLR 301 preserves general jurisdiction where New York courts historically could exercise it. For an individual, domicile is the central basis. For a corporation, doing business in New York with a substantial, continuous and systematic presence has historically mattered under state doctrine, but constitutional limits require attention to where the corporation is at home. A corporation's sales or employees in New York do not automatically create all-purpose jurisdiction for unrelated claims.

A national corporation may conduct extensive business in New York yet be incorporated and headquartered elsewhere. A claim unrelated to New York activity requires careful general-jurisdiction analysis; do not assume that volume alone makes the corporation at home. By contrast, a claim connected to a deliberate New York transaction may support specific jurisdiction even when general jurisdiction is absent.

Due process focuses on purposeful contacts and fairness

Constitutional due process asks whether the defendant purposefully established contacts with New York and whether the claim is sufficiently related to those contacts. The plaintiff's unilateral activity cannot create the defendant's forum relationship. If the required contacts exist, consider whether exercising jurisdiction is reasonable in light of the burden on the defendant, New York's interest, the plaintiff's interest and efficient resolution.

A foreign manufacturer whose product reaches New York through an independent distributor is not automatically subject to jurisdiction merely because injury occurs there. Evidence that the manufacturer targeted the market, designed a distribution system for it or regularly served New York customers can affect the analysis. Use facts about the defendant's own choices, not only the product's final location.

Service, consent and waiver

Personal jurisdiction and service are distinct. A court may have a statutory and constitutional basis but lack valid service. Conversely, perfect service does not create a missing jurisdictional basis. Identify the authorized method, who completed service, what papers were delivered and whether proof was filed as required.

Consent and litigation conduct can affect the personal-jurisdiction defense. A defendant can agree to a forum clause or waive objections by failing to raise them in the required manner. Analyze what the defendant did and when. Do not conclude that the court has general jurisdiction simply because the defendant appeared, or that a preserved objection defeats jurisdiction on its merits.

A complete worked analysis

A New Jersey consultant contracts with a New York retailer to advise on store operations. The consultant visits New York twice, conducts remote planning for six months and receives monthly payments. The retailer sues in New York alleging that the advice breached the agreement. Identify CPLR 302(a)(1), then examine the purposeful New York transactions and whether the claim arises from them. The visits, New York-directed work and continuing relationship support a connection stronger than the client's residence alone. Apply due process to the consultant's own contacts and the fairness factors. Separately determine whether service was proper.

If the same consultant were sued over an unrelated accident in New Jersey, the contract contacts would not automatically support jurisdiction over that claim. Relatedness is essential to specific jurisdiction. A strong answer states the statutory basis, claim connection, constitutional analysis and service issue as separate conclusions.
