Liability Waiver In California: How It Works (2026)

What Makes a Waiver Valid?

A liability waiver in California is only valid if it has clear and explicit language. The waiver must state the activity it’s for, and it must express that the signer is releasing the other party from the potential of being sued. The writing must be legible as well. Additionally, the signer must not have been coerced into agreeing to the waiver.

Ordinary vs. Gross Negligence

Liability waivers in California cover ordinary negligence. This is the failure to use reasonable care to prevent harm from occurring.

Under California law, however, no one can write release and waiver forms (or any other contract) to protect themselves from the consequences of willful, reckless or harmful conduct. Releases of future gross negligence are usually not enforceable because they are against public policy. Gross negligence is a “want of even scant care” or actions that are a “departure from the ordinary standard of conduct.”

In the City of Santa Barbara v. Superior Court (2007), California’s Supreme Court ruled that a waiver signed by a parent did not bar the filing of a gross negligence claim after a child drowned at a city camp.

What the 2025 Whitehead Decision Changed

The Whitehead case of 2025 held that a release cannot bar claims for negligent violations of a duty enacted for public safety purposes. This means that a signed waiver does not forbid a claim if the defendant violated a safety statute.

Whether You Must Sign One

You are never forced to sign a liability waiver in California, but businesses can refuse you their services. You do not have to sign one if the waiver violates a statute or if the waiver involves public interest, like medical care or essential public services.

When a Waiver Affects the Public Interest

The courts will look at the Tunkl factors to determine whether the waiver affects public interest. They’ll look at whether the business is open to the public, is of a type suitable for public regulation, performs a necessary service, has a decisive bargaining advantage, uses a standardized adhesion contract without offering the chance to buy protection and places the signer under its control.

Most of the time, recreational activities fail this test.

Can a Minor Sign a Waiver?

Those under the age of 18 may enter a contract, but they can disaffirm it before they turn 18 or within a reasonable time. This means that the waiver is voidable unless a parent or guardian signs, too. If a parent or guardian signs the waiver, it would bar the pursuit of an ordinary negligence claim.

Filing a Claim After Signing

Even if you signed a liability waiver, it may be possible to begin a claim if you sustained harm as a result of gross negligence, recklessness or intentional misconduct. The same applies if the language is vague or if a safety statute was violated.

Key Parts of the Waiver Form

The waiver form must clearly state the names of the parties involved, the activity the waiver addresses and a description of the risks involved. It must contain a clause that states the form was signed voluntarily. It also needs to have a release of liability section that outlines that the signer is releasing the other party from the risk of being sued. That section works much like an exculpatory clause inside a broader contract.

These forms usually contain an indemnification clause, which states that the signer will be responsible for damages and fees if they break the contract. There should be a provision stating which law governs the agreement in the event of a dispute.

Additionally, you may encounter a clause that waives Civil Code 1542. This code states that the release does not extend to claims the releasing party isn’t aware of and that would have materially impacted a settlement.
