Is a Liability Waiver Enforceable in California? A San Francisco Lawyer’s 10-Point Checklist
Every gym membership, rock-climbing gym waiver, youth soccer registration, and dog-walking app in California asks for a signature before you can participate, and nearly every one of those documents tells you, in bold print, that you’re giving up your right to sue. Most people sign without reading past the first paragraph. Most people also assume that signature is the end of the story if they get hurt.
It usually isn’t. California courts read liability waivers narrowly, and a release that looks airtight on the page can fail in front of a judge for reasons that have nothing to do with how thorough the paperwork looked. Understanding why starts with a single sentence buried in the California Civil Code.
The Rule Almost No One Reads: Civil Code Section 1668
California Civil Code section 1668 means no waiver, no matter how it’s worded, ever protects a business from its own fraud, willful injury, or a violation of law. That last category covers more ground than most waiver drafters expect. In 2025, the California Supreme Court gave it real teeth in Whitehead v. City of Oakland, holding that a signed release could not excuse a negligent breach of Government Code section 835, the statute requiring cities to keep their roadways safe for foreseeable uses like cycling. A cyclist who had signed a standard event release still had a live claim against the city after a pothole on a downhill training ride caused his crash, because the claim traced back to a negligent violation of a public-safety statute, not ordinary negligence.
Gross negligence is a separate, and separately absolute, bar. We cover it below.
That still leaves plenty of room for California to enforce a waiver of ordinary negligence: a slip, a fall, a routine mishap during a normal activity. But “ordinary negligence” is doing a lot of work in that sentence, and getting there requires clearing several more hurdles.
When a Waiver Faces a Higher Bar: The Tunkl Test
Not every waiver gets treated the same way. In Tunkl v. Regents of University of California, the California Supreme Court held that a release affecting the public interest can’t stand, even for ordinary negligence, and laid out six factors courts still use today to decide whether a transaction “affects the public interest”:
- The business is one generally thought suitable for public regulation.
- The business is performing a service of great importance to the public, often a practical necessity for some members of the public.
- The business holds itself out as willing to perform the service for any member of the public who seeks it.
- Because of the essential nature of the service, the business has a decisive bargaining advantage over anyone seeking the service.
- In exercising that advantage, the business presents a standardized, take-it-or-leave-it release, with no option to pay more for protection against negligence.
- The person or property of the customer is placed under the business’s control, subject to the risk of the business’s (or its agents’) carelessness.
Medical care, essential utilities, and certain licensed services tend to check most or all of these boxes. A rock-climbing gym or a recreational sports league usually doesn’t. Courts have repeatedly held that voluntary recreational activities don’t “affect the public interest” the way hospital admission forms do, which is a big part of why gym and sports waivers get enforced far more often than people assume. The Tunkl factors aren’t a technicality; they’re the difference between “you can’t sue at all” and “you can.”
Gross Negligence Is Never on the Table
Regardless of which side of the Tunkl line a business falls on, one door stays permanently closed: gross negligence. In City of Santa Barbara v. Superior Court, the California Supreme Court held that a release from liability for future gross negligence is unenforceable as a matter of public policy, categorically and not case by case.
Gross negligence isn’t just a worse version of an ordinary mistake. Courts describe it as an extreme departure from what a reasonably careful business would do, or a conscious disregard for safety. A gym that fails to secure a piece of equipment the manufacturer explicitly warned against is a very different case than a member simply tripping over their own shoelaces, and California courts have let cases like the first one through a signed waiver more than once. Jimenez v. 24 Hour Fitness is the case most California injury lawyers point to: a fitness center’s failure to follow a documented six-foot safety clearance around a treadmill was enough to send the gross-negligence question to a jury, waiver or no waiver.
Vague or Buried Language Doesn’t Hold Up
Even a waiver that clears the Tunkl and gross-negligence hurdles still has to actually say what it means to say. California courts require a release to be clear, unambiguous, and conspicuous: not hidden in dense fine print, not contradicted by other language in the same document, and not so generic that it’s unclear what risk was actually being released.
That doesn’t mean a waiver has to use the word “negligence” verbatim. In Sanchez v. Bally’s Total Fitness Corp., the court upheld a release that never used that specific word, reasoning that its language plainly covered injuries arising from ordinary use of the facility. What matters is whether an ordinary person reading the document would understand what they were giving up. A waiver that describes one narrow activity doesn’t automatically cover an unrelated risk the business never disclosed.
Other Ways a Waiver Gets Thrown Out
Beyond the Tunkl test, gross negligence, and clarity, several other issues come up again and again in California waiver litigation:
It doesn’t name the right party. A release that identifies the wrong entity, or omits a related company entirely, may not protect the party actually being sued.
It was signed under unequal bargaining power. A release presented as a rigid, take-it-or-leave-it condition of service, with no ability to negotiate or pay for different terms, invites more scrutiny than one both sides actually discussed.
There was no real consideration. A waiver needs something of value exchanged for it, though for most pre-injury recreational releases, simply being allowed to participate is enough. This ground rarely knocks out a waiver on its own, but it’s worth checking when a release was tacked onto unrelated paperwork with nothing exchanged for it specifically.
A minor signed it, or a parent signed on a minor’s behalf. This isn’t an automatic win. California courts have upheld a parent’s pre-injury release of a child’s ordinary-negligence claims in recreational and school settings (Hohe v. San Diego Unified School Dist.). What a parent’s signature can’t do is waive gross negligence, fraud, or a Tunkl-type public-interest claim on the child’s behalf; those still proceed, typically through a guardian ad litem rather than waiting until the child turns eighteen.
The injury doesn’t match what was released. A waiver for the ordinary risks of yoga class doesn’t necessarily cover a defective piece of equipment, a poorly maintained facility, or an assault by staff. Courts look at whether the actual mechanism of harm falls inside what the release described.
One related distinction: a signed release is different from primary assumption of risk, the doctrine that says a business owes no duty at all for the ordinary, inherent risks of a sport like skiing or rock climbing (Knight v. Jewett), whether or not anyone signed anything. A waiver and assumption of risk often get raised together, but a court can reject the waiver on one of the grounds above and still rule for the defendant on assumption of risk, or the reverse.
The Waiver Enforceability Checklist
Because so many of these questions turn on the same handful of facts, it helps to run any signed waiver through the same list a lawyer would use before concluding it’s a dead end:
- Does it specifically describe the activity and the risks?
- Is the language clear, unambiguous, and easy to find?
- Does it correctly name the party being released?
- Does it try to excuse gross negligence?
- Does it try to excuse fraud, willful injury, or a statutory violation?
- Was it signed voluntarily, without unequal bargaining power?
- Was there real consideration for signing it?
- Does the transaction affect the public interest under the Tunkl factors?
- Did a minor sign it, or was it signed on a minor’s behalf?
- Does it match the injury that actually happened?
A “no” on even one of these doesn’t guarantee a win, but it’s usually enough to get a case past the waiver defense and in front of a jury on the merits.

A Different Standard for Rides, Buses, and Other Common Carriers
One category of waiver deserves its own note: gravity-propelled rides, ski lifts, buses, and other transportation that California treats as a “common carrier” under Civil Code section 2100. Common carriers owe passengers the “utmost care and diligence,” a much higher standard than ordinary reasonable care, and Civil Code section 2175 goes further than the general rule above: a common carrier can’t contract out of liability for gross negligence, fraud, or willful wrongdoing at all. We broke down exactly how that plays out in the Six Flags X2 roller coaster litigation, where a signed ticket waiver was never going to be the end of the conversation for a ride carrying that legal classification.
If You Signed a Waiver and Got Hurt
Don’t assume the waiver decides anything on its own. Preserve whatever documentation exists, including the waiver itself, photos of the condition or equipment that caused the injury, and the names of anyone who witnessed it, and get medical treatment documented promptly. California’s statute of limitations gives most injury claims two years to be filed, but the evidence that actually proves notice, gross negligence, or a mismatch between the waiver and the injury tends to disappear long before that deadline arrives.

Frequently Asked Questions
Sometimes. California generally allows a business to release itself from liability for ordinary negligence in a private transaction, but courts apply several tests, including the Tunkl public-interest factors, a clarity requirement, and an absolute bar on gross negligence, before enforcing one. Whether a specific waiver holds up depends on the exact document and the facts of the injury.
No. The California Supreme Court held in City of Santa Barbara v. Superior Court that a release from liability for future gross negligence is unenforceable as a matter of public policy, in any setting California courts have considered.
It’s a six-factor test from Tunkl v. Regents of University of California used to determine whether a transaction “affects the public interest.” If it does, a waiver of even ordinary negligence generally cannot stand. Essential services like medical care tend to meet the test; voluntary recreational activities usually don’t.
Not necessarily. A waiver only covers what it actually and clearly describes, and it can never cover gross negligence, fraud, or willful misconduct. Many injury claims proceed despite a signed release once the document and the facts are examined closely.
In part. California courts have upheld a parent’s pre-injury release of a child’s ordinary-negligence claims in recreational and school settings (Hohe v. San Diego Unified School Dist.), which is a frequent issue in youth sports programs. What a parent’s signature can’t do is waive gross negligence, fraud, or a Tunkl-type public-interest claim on the child’s behalf; those claims still proceed, typically through a guardian ad litem.
Not always. Rides and other transportation that qualify as common carriers under California law owe passengers a higher “utmost care and diligence” standard, and their waivers face an even steeper climb than an ordinary gym or recreational release.
If the language doesn’t clearly and specifically describe the activity and its risks, or is buried in fine print that contradicts other terms, California courts are less likely to enforce it. An ordinary person has to be able to understand what they were giving up.
Yes. Waiver enforceability depends heavily on the specific document and the specific facts, and many people assume a case is over based on paperwork that a court would actually strike down.
