California Civil Code Section 1668 voids any contract that tries to shield a party from liability for their own fraud, willful injury to another person or property, or violation of law, whether that violation is willful or negligent. The statute is one sentence long, but California courts have built a substantial framework around it that also reaches many ordinary-negligence waivers when the service involved affects the public interest. Whether a given release holds up depends on the type of activity, the bargaining power between the parties, how the waiver is drafted, and whether the conduct at issue crosses into gross negligence.
The Text of the Statute
Section 1668 provides that all contracts which have as their object, directly or indirectly, to exempt anyone from responsibility for their own fraud, willful injury to the person or property of another, or violation of law, whether willful or negligent, are against the policy of the law.1California Legislative Information. California Civil Code 1668
Notice what the statute doesn’t say. It doesn’t mention ordinary negligence by name. It doesn’t declare all liability waivers void. What it does is identify three categories of conduct that can never be shielded by contract. Everything else, including whether a waiver for everyday carelessness will stand, comes from decades of court decisions interpreting those boundaries.
Fraud and Willful Injury
The most absolute prohibition in Section 1668 targets fraud. A business cannot use a contract to escape liability for deliberately deceiving someone. If a seller makes false claims to get a buyer to sign an agreement, the release is void as to those deceptive acts. No amount of fine print changes that.1California Legislative Information. California Civil Code 1668
The same goes for willful injury. When someone intentionally causes harm to another person or their property, a signed release provides no protection. A facility manager who deliberately ignores a known danger, or a provider who assaults a customer, cannot point to a waiver and walk away. The reasoning is straightforward: allowing contracts to excuse deliberate harm would create an incentive to hurt people as long as they had signed something first.
Violations of Law
Section 1668 separately prohibits waivers that cover violations of law, and it applies whether the violation was intentional or merely negligent. A company that ignores a building code, skips a required safety inspection, or fails to comply with health regulations cannot use a waiver to dodge liability for injuries that result. Statutory safety requirements reflect a public decision about minimum standards, and private contracts cannot override those standards.1California Legislative Information. California Civil Code 1668
Litigation in this area usually turns on whether the violated statute was meant to protect the type of person who got hurt. A worker injured because an employer ignored a Labor Code safety requirement is exactly the kind of person that regulation was designed to protect, and a general liability waiver will not save the employer. This category is broader than many businesses realize, because it reaches negligent violations, not just intentional ones.
The Tunkl Public Interest Test
The most important expansion of Section 1668 came in 1963, when the California Supreme Court decided Tunkl v. Regents of University of California. The case involved a hospital that required patients to sign a waiver releasing it from negligence liability as a condition of admission. The court struck down the waiver and set out a six-factor test for identifying when an exculpatory clause violates public policy, even if it only covers ordinary negligence.2Justia. Tunkl v. Regents of University of California
The Tunkl factors ask whether:
- The business is of a type generally thought suitable for public regulation.
- The service is of great importance to the public and often a practical necessity for some members of the public.
- The provider holds itself out as willing to serve any member of the public who meets established standards.
- The provider has a decisive bargaining advantage because of the essential nature of the service.
- The provider presents a standardized take-it-or-leave-it agreement with no option to pay more for negligence protection.
- The transaction places the person or their property under the provider’s control, subject to the risk of the provider’s carelessness.
Not every factor needs to be present for a court to strike down a waiver, but the more factors that apply, the stronger the case. Hospital care, the context of Tunkl itself, checks every box. Courts have since applied the factors to other essential services. Residential leases are a common example: because housing is a basic necessity and tenants typically face a standardized agreement with little room to negotiate, California courts have generally refused to enforce landlord exculpatory clauses for negligent property maintenance.2Justia. Tunkl v. Regents of University of California
When Negligence Waivers Are Enforceable
The other side of Tunkl is that waivers covering ordinary negligence are enforceable when the activity doesn’t implicate the public interest. Recreational and leisure activities aren’t necessities, so the power imbalance that drives the Tunkl analysis generally isn’t there. If you voluntarily sign up for a gym membership, a ski trip, a marathon, or a boat rental, the waiver you sign can protect the operator from claims based on ordinary carelessness.3FindLaw. Capri v. Fitness International LLC
Nobody is forced to join a gym or go skydiving. You choose a voluntary activity for personal enjoyment, and the release you sign reflects a genuine bargain: you accept the risks in exchange for access. In Benedek v. PLC Santa Monica, the Court of Appeal held that exculpatory agreements in the recreational sports context don’t implicate the public interest and aren’t void as against public policy.4FindLaw. Benedek v. PLC Santa Monica LLC
The same one-page liability release can be completely void in one setting (a hospital admission form) and perfectly enforceable in another (a rock-climbing gym membership). The difference is not the wording but the nature of the underlying service.
Gross Negligence Cannot Be Waived Either
Even in a purely recreational context where a negligence waiver would normally hold, the release cannot cover gross negligence. The California Supreme Court settled this in City of Santa Barbara v. Superior Court, holding that a release of liability for future gross negligence in a sports or recreational program is unenforceable as a matter of public policy.
Ordinary negligence is the failure to exercise reasonable care, such as a gym not immediately noticing a frayed cable on a machine. Gross negligence involves an extreme departure from the standard of care, showing reckless disregard for others’ safety. A gym that knows a machine’s cable is about to snap, does nothing about it, and lets members keep using it has crossed from carelessness into something much worse.
In practice, the gross negligence question is often the central dispute when a defendant tries to enforce a recreational waiver. The plaintiff argues the conduct was so far below the standard of care that it amounts to gross negligence, which the waiver cannot reach. The defendant argues the conduct was merely ordinary negligence, which the waiver does cover. Where courts draw that line is fact-specific, but the key signal is whether the defendant consciously disregarded a known risk rather than simply failing to notice one.
Drafting Requirements for a Valid Waiver
Even where a negligence waiver is legally permitted, the document itself has to meet certain standards. California requires the release to be clear, unambiguous, and explicit about what liability is being given up. Vague or buried language is a red flag.
A few practical issues come up repeatedly in litigation. A release printed in tiny font, tucked onto the back of a form, or buried deep in a multi-page contract is far less likely to hold up than one presented prominently on its own page. The waiver should reference “negligence” by name, so a court can see the signer understood they were giving up the right to sue for someone else’s carelessness rather than just accepting inherent risks. And the scope must match the claim: a waiver releasing liability for injuries during a fitness class will not necessarily cover a slip on a wet lobby floor.
Drafting quality matters, but it cannot save a waiver from the substantive limits of Section 1668. If the underlying conduct involves fraud, intentional harm, a statutory violation, or gross negligence, the release fails regardless of how carefully it was written.
Waivers Signed by Parents for Minor Children
Parents routinely sign liability waivers on behalf of their children for school field trips, sports leagues, and summer camps. In California, these parental waivers are generally enforceable for ordinary negligence. The Court of Appeal established this principle in Hohe v. San Diego Unified School District, holding that a parent has authority to contract on behalf of their child, and the child cannot later disaffirm the release based on being a minor at the time.5Justia. Hohe v. San Diego Unified School District
The same substantive limits still apply. A parental waiver cannot release an organization from liability for gross negligence, intentional harm, or violations of law. The waiver also has to be signed by the parent or guardian; a minor’s own signature on a contract is generally voidable. Within those limits, California law gives parents broad authority to accept risk on their child’s behalf, particularly for school-related or recreational activities.
Employment Waivers
Employment is one of the clearest areas where Section 1668’s principles bite hard. Workers’ compensation is mandatory in California, and employees cannot waive their right to those benefits. Any employment agreement trying to release an employer from workplace injury liability runs directly into the public policy concerns Section 1668 embodies: the employee has minimal bargaining power, the relationship isn’t voluntary in any meaningful economic sense, and workplace safety is heavily regulated.
Federal workplace safety law reinforces these limits. OSHA has ruled that asking employees to sign liability waivers in exchange for required safety measures, such as the hepatitis B vaccine mandated under the bloodborne pathogen standard, violates federal regulations because it imposes a cost on the employee for something the employer must provide for free.6Occupational Safety and Health Administration. Permissibility of a Consent Form With a Waiver of Liability
Courts evaluating workplace waivers consistently find them to be adhesion contracts, meaning take-it-or-leave-it agreements where the employee has little bargaining power. That combination of regulatory mandates, unequal bargaining position, and public policy concerns makes employment one of the hardest contexts in which to enforce any kind of liability release.
Federal Law That Overrides State Waiver Rules
Even when a waiver might survive Section 1668, federal law can independently void it. Two areas come up most often for California businesses.
Commercial Passenger Vessels
Federal law flatly prohibits liability waivers for personal injury or death on commercial passenger vessels. Under 46 U.S.C. ยง 30527, the owner or operator of a vessel carrying passengers between U.S. ports, or between a U.S. port and a foreign port, cannot include any contract provision limiting liability for negligence-caused personal injury or death, or restricting the passenger’s right to trial. Any such provision is void.7Office of the Law Revision Counsel. 46 USC 30527 – Provisions Limiting Liability for Personal Injury or Death
This matters for California’s harbor cruise operators, whale-watching companies, and ferry services. A waiver that would be perfectly enforceable for a land-based recreational activity is automatically void the moment it applies to a commercial passenger vessel, regardless of what California state law would allow.
ADA Compliance
The Americans with Disabilities Act is a federal civil rights statute, and its requirements cannot be waived by contract. Even if a landlord and tenant agree in a lease to allocate ADA responsibilities between them, both parties remain fully liable for compliance. State and local officials have no authority to grant variances from ADA requirements, and no private agreement can create an exemption.8ADA.gov. ADA Title III Technical Assistance Manual
For California businesses, a liability waiver asking customers to release claims related to accessibility barriers is unenforceable under federal law, regardless of how it would be treated under Section 1668 alone.
