An NDA breach in California can trigger civil lawsuits, court-ordered injunctions, monetary damages, and in cases involving trade secret theft, even criminal charges under state and federal law.

What actually happens if someone violates a non-disclosure agreement in California? The short answer is it depends on what the agreement covers, what was disclosed, and how much harm resulted. Remedies can range from court-ordered injunctions stopping further disclosure to significant monetary damages for lost profits and unjust enrichment. If trade secrets are involved, criminal penalties may also apply. Whether you are enforcing an NDA or defending against an alleged breach, a California business law attorney at Schneiders & Associates, L.L.P. can evaluate your situation and guide you toward the strongest path forward.

What Does It Mean to Breach an NDA Under California Law?

A non-disclosure agreement (NDA) is a legally binding contract that restricts the sharing of confidential information between parties. Businesses enter into NDAs with employees, contractors, and third parties to prevent other parties from disclosing or misusing information gained by virtue of their relationship with the company. An NDA can protect trade secrets, intellectual property, client and customer lists, and other types of sensitive information that are of financial interest to the business.

A breach occurs when a party violates any of the obligations contained in the non-disclosure agreement. For example, a party privy to information the NDA protects may choose to make an unauthorized disclosure of that information to third parties or sell the information.

Another way a party may violate an NDA is to use the protected information for their own personal or financial gain, such as taking customer lists and then attempting to siphon off those customers for a new business. A breach can also occur when parties who gain access to protected information fail to implement proper security measures, such as safeguards to prevent unauthorized access to servers where the information is stored.

Not every disclosure qualifies as a breach, however. If the information was already publicly available, independently developed, or disclosed under a court order or legal obligation, a breach claim may not hold up. Understanding the line between a genuine violation and a defensible disclosure is where experienced legal counsel becomes critical.

Legal Consequences of Breaking an NDA in California

If a California NDA is breached, the parties that suffered harm may be able to ask a court to enforce the agreement. The remedies available generally fall into several categories, and more than one may apply in a single case.

Injunctive Relief 

Injunctive relief prohibits a party from engaging in some sort of action. For instance, using or selling the information that they acquired in violation of the NDA. For the party that misappropriated the protected information, the injunction could destroy their business. Courts can issue temporary restraining orders and preliminary injunctions quickly to stop further damage while a case is pending.

Specific Performance 

The court may require the offending party to take some affirmative action to correct whatever was done, depending on the exact language of the agreement. This might include returning confidential documents, deleting proprietary files, or notifying recipients that information was shared without authorization.

Monetary Damages 

Compensation for victims based on the losses they suffered because of the breach, which could be substantial. Damages may include the plaintiff’s actual losses and the defendant’s profits gained from the misappropriation. In cases of willful misconduct where malice or oppression is shown, punitive damages may be awarded. Some NDAs also include liquidated damages clauses that set a predetermined penalty for breach.

Criminal Charges 

There could be criminal charges associated with an NDA breach, particularly cases involving unauthorized access to electronic data or trade secret theft. Theft of trade secrets is a serious felony offense under California Penal Code Section 499c that can result in lengthy prison sentences for those convicted. The federal Defend Trade Secrets Act provides an additional cause of action when trade secrets are connected to interstate commerce.

How California Courts Evaluate NDA Enforceability

Not every NDA will survive court scrutiny. California courts do not treat every NDA as enforceable on sight, because the state has a strong policy favoring open competition and employee mobility. If a confidentiality clause quietly operates like a non-compete, the contract can fall apart in litigation.

Several factors determine whether an NDA is enforceable:

Specificity of Terms

The NDA must be clearly written, detailing the confidential information and the extent of the confidentiality obligation. Vague or overbroad language that sweeps in general knowledge is a common reason NDAs fail.

Reasonable Scope and Duration

The terms must be reasonable in what is considered confidential and in the duration of the obligation. An NDA without a defined time frame may face enforceability challenges.

Compliance with California Public Policy

California Business and Professions Code Section 16600 sets the tone by voiding contracts that restrain a lawful profession or trade. An NDA that effectively prevents a former employee from working in their field may be struck down as an unlawful non-compete.

Whistleblower and Harassment Protections

Under California’s Silenced No More Act (SB 331), NDA provisions in settlement agreements preventing discussion of harassment, discrimination, retaliation, or illegal activity reporting are void. NDAs also cannot be used to prevent the reporting of illegal activity or to silence a whistleblower.

The main law governing NDAs involving trade secrets in California is the California Uniform Trade Secrets Act (CUTSA), codified in sections 3426 through 3426.11 of the California Civil Code. Under CUTSA, the protected information must derive independent economic value from its secrecy and the owner must have taken reasonable steps to keep it secret.

Real-World Scenarios Where NDA Breaches Arise

NDA disputes do not always involve dramatic corporate espionage. Many cases involve everyday business transitions that go sideways. Here are common scenarios California businesses encounter:

Employee departures. A sales manager resigns and takes a confidential client list to a competing firm. If the NDA clearly defined that list as protected information and the employer took reasonable steps to restrict access, this is a straightforward breach. However, if the employee argues the contacts were personal relationships developed over years, the case becomes more nuanced.

Independent contractor disclosures. A freelance developer shares a client’s proprietary code or marketing strategy with another client in the same industry. Because contractor relationships often lack the same oversight as employment, these breaches can be harder to detect early, making strong NDA language essential from the outset.

Business sale due diligence. During acquisition negotiations, both parties exchange sensitive financial and operational data under mutual NDAs. If the deal falls through and the prospective buyer uses that information to compete, a breach claim may follow. These disputes highlight why NDAs for business transactions should include specific return-or-destroy provisions.

Inadvertent disclosures and data leaks. Not every breach is intentional. An employee may accidentally forward a confidential document to the wrong recipient, or a security lapse may expose protected data. Whether an inadvertent disclosure constitutes a breach depends largely on the NDA’s language and whether the party failed to implement required safeguards.

Frequently Asked Questions About NDA Violations in California

Can you go to jail for breaking an NDA?

Most NDA breaches are handled as civil matters, resulting in lawsuits rather than criminal charges. However, California law may impose criminal penalties for stealing trade secrets under Penal Code Sections 499c and 502.

Theft of trade secrets is a felony-level offense punishable by up to three years in prison. Criminal exposure typically requires intentional theft or unauthorized access, not a simple contractual dispute.

How long do you have to file a lawsuit for an NDA breach?

An action for trade secret misappropriation must be brought within three years after the misappropriation is discovered or by the exercise of reasonable diligence should have been discovered. For a standard breach of contract claim not involving trade secrets, California’s statute of limitations is four years. Acting promptly preserves evidence and strengthens your position.

Can an NDA be enforced if the information becomes public?

Once information enters the public domain through no fault of the receiving party, enforcing the NDA becomes significantly more difficult. Enforcing an NDA may be challenging once information becomes public, unless the disclosure was wrongful and the damages extend beyond public knowledge. If the breach itself caused the information to become public, the breaching party may still be liable for the resulting harm.

Are NDAs enforceable against former employees in California?

While California imposes strict limitations on NDAs, they are still enforceable when used to protect trade secrets, such as recipes, algorithms, or manufacturing processes, as well as intellectual property and proprietary business strategies. NDAs that are narrowly tailored to protect genuinely confidential information without restricting an employee’s ability to work in their field remain valid and enforceable.
