California Personal Jurisdiction Statute: Contacts and Consent

The California personal jurisdiction statute, California Code of Civil Procedure Section 410.10, gives state courts authority to exercise jurisdiction on any basis the U.S. and California Constitutions allow.¹ That single sentence is one of the broadest long-arm provisions in the country, and it means the real question in almost every California jurisdiction dispute is not statutory but constitutional: does hauling this particular defendant into a California court satisfy federal due process?

What Section 410.10 Actually Says

The statute reads in full: “A court of this state may exercise jurisdiction on any basis not inconsistent with the Constitution of this state or of the United States.” Many states list specific activities that trigger jurisdiction, like transacting business or causing injury in the state. California does not. It simply extends its reach to the constitutional maximum.

The practical consequence is that California courts skip the statutory checklist other states work through and go straight to the due process analysis. There is no bright-line list of qualifying acts. Every case turns on the defendant’s specific relationship with California.

General Jurisdiction vs. Specific Jurisdiction

The due process inquiry branches in two directions. Confusing them is one of the most common errors in jurisdictional disputes because each has its own standard and its own consequences.

General Jurisdiction: When a Defendant Is “At Home”

General jurisdiction lets a California court hear any claim against a defendant, even one unrelated to California, when the defendant’s ties to the state are deep enough that the defendant is essentially “at home” there. For individuals, that usually means domicile. For corporations, the U.S. Supreme Court in Daimler AG v. Bauman (2014) narrowed general jurisdiction to two paradigm locations: the state of incorporation and the state where the corporation has its principal place of business.² Even substantial and continuous business operations in California generally do not satisfy the “at home” threshold after Daimler.

Specific Jurisdiction: When the Claim Arises from California Contacts

Specific jurisdiction covers most disputes. It applies when the plaintiff’s claims arise out of or relate to the defendant’s contacts with California.³ The defendant’s overall presence in California does not need to be deep, but there must be a direct link between what the defendant did in or toward California and what the suit is about.

The Supreme Court sharpened that link requirement in Bristol-Myers Squibb Co. v. Superior Court (2017). Hundreds of out-of-state plaintiffs sued the pharmaceutical company in California over injuries from a blood-thinning drug. The Court held that California lacked specific jurisdiction over the nonresidents’ claims because their injuries did not arise from the company’s California contacts. It made no difference that Bristol-Myers sold the same drug in California and had substantial operations there. The out-of-state claims had no connection to those California activities.⁴

The Minimum Contacts Requirement

Both paths trace back to International Shoe Co. v. Washington (1945), where the Supreme Court held that a state may exercise 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. A single purposeful act aimed at California can be enough. A thousand incidental contacts might not be.

Purposeful Availment

The central concept is “purposeful availment.” The defendant must have deliberately reached into California and taken advantage of the chance to do business there or otherwise benefit from the state’s laws. Unilateral acts by someone else, like a California resident buying a product elsewhere and bringing it home, do not count.⁵

In Burger King Corp. v. Rudzewicz (1985), the Supreme Court held that when a defendant creates “continuing obligations” with a resident of the forum state, the defendant should reasonably anticipate being sued there.⁶ California courts apply that reasoning to business contracts, licensing deals, and other ongoing relationships with California residents. The right question is not whether a defendant could have predicted its product ending up in California, but whether the defendant’s own conduct built a connection that made a California lawsuit foreseeable.⁷

The Effects Test in Tort Cases

For intentional torts, California courts often apply the “effects test” from Calder v. Jones (1984). That case involved a Florida-based National Enquirer reporter and editor who wrote an allegedly defamatory article about a California entertainer. The Supreme Court held that jurisdiction was proper because the defendants committed an intentional act expressly aimed at California and knew the brunt of the harm would be felt there.⁸

Awareness that a California resident might be affected is not enough. In Pavlovich v. Superior Court (2002), the California Supreme Court declined jurisdiction over a Texas resident who posted DVD copy-protection circumvention software online. General awareness that the entertainment industry sits in California did not amount to expressly aiming conduct at the state.⁹ The defendant’s conduct itself must target California.

Stream of Commerce

Products that flow through a distribution chain into California raise their own questions. In Asahi Metal Industry Co. v. Superior Court (1987), a Japanese manufacturer sold tire valve parts to a Taiwanese company, and the components ended up in tires sold in California. The Supreme Court held that placing a product into the stream of commerce with mere awareness that it might reach California is not enough.¹⁰ Something more is needed: designing for the California market, advertising here, setting up distribution channels, or otherwise taking affirmative steps to serve California customers.

The Reasonableness Check

Even when minimum contacts exist, jurisdiction can still fail a second, independent test. 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 substantive policy interests of the several states.

These factors rarely defeat jurisdiction when contacts are strong. In borderline cases, though, an unreasonable burden or a weak state interest can tip the balance. In Asahi, for example, the Court emphasized that requiring a Japanese manufacturer to defend a warranty claim in California, when all the relevant events happened in Asia, placed an unreasonable burden on the defendant.

Consent and Waiver

A defendant can be subject to California jurisdiction without any minimum contacts analysis at all, either by agreeing to it in advance or by failing to object at the right time.

Forum Selection Clauses

Contracts often designate California as the forum for disputes. California courts enforce these clauses unless the challenger shows enforcement would be unreasonable. The California Supreme Court in Smith, Valentino & Smith, Inc. v. Superior Court (1976) held that forum selection clauses are valid and enforceable at the court’s discretion, provided they reflect a free and voluntary choice.¹¹ A clause obtained through fraud or one that would deny a party any real remedy is more vulnerable, but the general presumption favors enforcement.

Corporate Registration After Mallory

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

Waiver Through Litigation Conduct

Failing to challenge jurisdiction at the outset can waive the objection entirely. Under California Code of Civil Procedure Section 418.10, a defendant contesting personal jurisdiction must file a motion to quash service of summons on or before the last day to file a responsive pleading.¹³ Filing an answer, participating in discovery, or engaging in substantive litigation before raising the objection signals acceptance of the court’s authority, and courts treat that as implied waiver.

Challenging Jurisdiction in California

An out-of-state defendant served with a California suit who believes the court lacks jurisdiction files a motion to quash service of summons under Section 418.10. The motion must be set for hearing within 30 days of filing. Filing the motion extends the deadline to respond to the complaint until 15 days after notice that the motion was denied. If the trial court denies the motion, the defendant has 10 days to petition the appellate court for review. The same motion can also raise an inconvenient forum objection.¹³

The plaintiff bears the initial burden of showing enough contacts to support jurisdiction. If the plaintiff meets that burden, the defendant must then show that exercising jurisdiction would be unreasonable under the five factors. Defendants should be ready to submit declarations and documentary evidence proving their lack of California connections. A bare denial rarely wins.

Internet Activity and Jurisdiction

A website is technically accessible everywhere, but not every website creates 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 company that marketed directly to California customers through its website, accepted online hotel reservations from them, and sent targeted promotional materials into the state.¹⁴ These were deliberate commercial interactions directed at California, not passive internet presence.

A purely informational page that anyone can read does not, on its own, create jurisdiction. A site that takes orders from California customers, contracts with California residents, or aims advertising at the California market looks much more like purposeful availment. The more interactive and commercially directed a website is toward California users, the stronger the case for jurisdiction here.
