California Personal Jurisdiction Statute: Minimum Contacts Test

California’s personal jurisdiction statute, Code of Civil Procedure Section 410.10, is a single sentence that lets state courts exercise jurisdiction on any basis the U.S. and California Constitutions allow.¹ Because the statute itself sets no narrower limit, the only real question in any California jurisdiction fight is a constitutional one: do federal due process standards permit the court to hear a case against this particular defendant?

What Section 410.10 Actually Says

The full text reads: “A court of this state may exercise jurisdiction on any basis not inconsistent with the Constitution of this state or of the United States.” Most states have long-arm statutes that list specific activities (transacting business, causing tortious injury, owning property) that trigger jurisdiction. California skips that step. The statute collapses the usual two-part analysis into one, sending courts directly to the constitutional inquiry.

That matters in practice. A plaintiff suing a nonresident in California does not need to fit the defendant’s conduct into a statutory category. A defendant challenging jurisdiction cannot win by arguing that the statute doesn’t reach them, because the statute reaches as far as the Constitution does. Every dispute turns on federal due process doctrine, which the U.S. Supreme Court has shaped through a long line of cases starting with International Shoe Co. v. Washington (1945).

General Jurisdiction and Specific Jurisdiction

Due process recognizes two kinds of personal jurisdiction, and they are not interchangeable.

General Jurisdiction

General jurisdiction lets a California court hear any claim against a defendant, including claims that have nothing to do with California, when the defendant is essentially “at home” in the state. For individuals, that usually means domicile. For corporations, the U.S. Supreme Court in Daimler AG v. Bauman (2014) limited general jurisdiction to the state of incorporation and the state of the principal place of business.² Doing substantial business in California is not enough on its own; after Daimler, general jurisdiction over corporations in California is largely confined to companies incorporated or headquartered here.

Specific Jurisdiction

Specific jurisdiction is the usual route. It applies when the lawsuit arises out of or relates to the defendant’s contacts with California. The defendant’s overall presence in the state can be modest, but there must be a real link between what the defendant did in or toward California and what the plaintiff is suing about.³

Bristol-Myers Squibb Co. v. Superior Court (2017) sharpened that link. Hundreds of nonresident plaintiffs sued Bristol-Myers in California over a blood-thinning drug. The U.S. Supreme Court held that California had no specific jurisdiction over the nonresidents’ claims because those injuries did not arise from the company’s California activities, even though the same drug was sold to Californians.⁴ Specific jurisdiction is claim-specific. Contacts that produced someone else’s injury do not carry over.

The Minimum Contacts Test

Both kinds of jurisdiction trace back to International Shoe, which allows personal jurisdiction over an out-of-state defendant only when the defendant has “minimum contacts” with the state such that the suit does not offend “traditional notions of fair play and substantial justice.”³ Quality of contacts matters more than quantity. One deliberate act aimed at California can be enough; many incidental contacts may not.

Purposeful Availment

The core requirement is purposeful availment. The defendant must have deliberately reached into California and taken advantage of the chance to do business or otherwise benefit from the state’s laws. A California resident buying something out of state and bringing it home does not create jurisdiction over the seller, because that contact is the buyer’s doing, not the seller’s.⁵

Burger King Corp. v. Rudzewicz (1985) applied this to contracts. The U.S. Supreme Court held that a Michigan franchisee who had entered a long-term franchise agreement with a Florida corporation could be sued in Florida, because he had created “continuing obligations” with a resident of that state and should reasonably have anticipated being called into court there.⁶ California courts apply the same reasoning to business transactions and licensing deals with California parties.

Foreseeability is part of the analysis, but not in the loose sense that a product might end up anywhere. The question is whether the defendant’s own conduct created a connection with California that would make being sued here foreseeable.⁷

The Calder Effects Test

Tort cases often turn on the “effects test” from Calder v. Jones (1984), which upheld California jurisdiction over Florida-based National Enquirer staff who wrote an allegedly defamatory article about a California entertainer. The U.S. Supreme Court found jurisdiction because the defendants committed an intentional act expressly aimed at California, knowing the brunt of the harm would land there.⁸

Mere awareness that a California resident might be hurt is not enough. In Pavlovich v. Superior Court (2002), the California Supreme Court declined jurisdiction over a Texas resident who posted DVD-decryption software online. The court held that general awareness of possible California harm did not amount to expressly aiming conduct at the state.⁹

Stream of Commerce

When a product reaches California through a distribution chain, placing it into the stream of commerce with awareness that it might end up here is not enough on its own. Asahi Metal Industry Co. v. Superior Court (1987) involved a Japanese manufacturer whose tire valve components reached California through a Taiwanese intermediary, and the U.S. Supreme Court held that awareness alone did not establish jurisdiction.¹⁰ Something more is needed: designing for the California market, advertising here, setting up distribution, or taking other active steps to serve California customers.

The Reasonableness Backstop

Even when minimum contacts exist, jurisdiction can still fail a separate reasonableness check. Courts weigh five factors drawn from Burger King and World-Wide Volkswagen Corp. v. Woodson (1980):⁶

The burden on the defendant of litigating in California.
California’s interest in adjudicating the dispute.
The plaintiff’s interest in obtaining convenient and effective relief.
The interstate judicial system’s interest in efficient resolution.
The shared interest of several states in advancing substantive social policies.

These factors rarely override strong contacts. But in close cases, an unreasonable burden or weak state interest can defeat jurisdiction. In Asahi, the Court stressed that making a Japanese manufacturer defend a warranty claim in California, when the relevant events happened in Asia, was unreasonable regardless of whether minimum contacts technically existed.

Consent and Waiver

A defendant can wind up subject to California jurisdiction without any minimum contacts analysis at all, by agreeing to it or by missing the moment to object.

Forum Selection Clauses

Contracts often designate California as the forum for disputes. In Smith, Valentino & Smith, Inc. v. Superior Court (1976), the California Supreme Court held that such clauses are valid and enforceable at the court’s discretion when they reflect a free and voluntary choice.¹¹ A clause obtained through fraud or that would leave a party with no real remedy is more vulnerable, but the general presumption favors enforcement.

Corporate Registration and Mallory

In Mallory v. Norfolk Southern Railway Co. (2023), the U.S. Supreme Court upheld a Pennsylvania statute requiring out-of-state corporations registering to do business there to consent to general jurisdiction on any claim.¹² California does not currently have a comparable registration-consent statute. Registering to do business in California does not, by itself, create consent to general jurisdiction here.

Waiver by Litigation Conduct

A defendant who wants to challenge personal jurisdiction must do it under Code of Civil Procedure Section 418.10, by moving to quash service of summons on or before the last day to file a responsive pleading.¹³ Filing an answer, taking discovery, or otherwise litigating the merits first is treated as an implied waiver of the objection, and once waived it is gone.

How to Challenge Jurisdiction

If you are served with a California lawsuit and believe the court has no jurisdiction over you, file a motion to quash service of summons under Section 418.10 and set it for hearing within 30 days of filing. Filing the motion extends your response deadline until 15 days after you receive notice that the motion was denied. If the trial court denies it, you have 10 days to petition the appellate court for review. The same motion can also raise an inconvenient forum objection when California is technically available but impractical.¹³

On the motion, the plaintiff bears the initial burden of showing enough contacts to support jurisdiction. If the plaintiff meets that burden, it shifts to the defendant to show that exercising jurisdiction would be unreasonable under the five-factor test. Expect to submit declarations and documents proving the absence of California connections. A bare denial rarely succeeds.

Internet Activity and Jurisdiction

Websites are accessible everywhere, but accessibility alone does not create jurisdiction everywhere. California courts look at what the defendant actually did online, not just whether Californians could reach the site.

In Snowney v. Harrah’s Entertainment, Inc. (2005), the California Supreme Court upheld jurisdiction over a Nevada casino that marketed directly to Californians through its website, took online reservations from them, and sent targeted promotional materials into the state.¹⁴ Those were deliberate commercial contacts, not passive presence.

A purely informational page that anyone can read does not, standing alone, support jurisdiction. A site that transacts with California customers, contracts with California residents, or targets California advertising looks much more like purposeful availment. The more a site actively engages the California market, the stronger the case that its operator can be sued here.
