Key Takeaways

• California broadly bans employee non-compete agreements. With narrow exceptions, they are void and unenforceable in the employment context.
• Recent laws strengthened the ban: they made it unlawful to even include a non-compete, extended the ban to out-of-state agreements, and gave employees a right to sue.
• A few narrow exceptions survive, mainly around the sale of a business and the dissolution of a partnership or LLC.
• The status of non-solicitation agreements is less settled, but courts have increasingly treated broad versions as void too.
• Because non-competes are largely off the table, California businesses protect themselves chiefly through trade-secret law and well-drafted confidentiality agreements.

California Non-Compete Agreements: What Business Owners Need to Know

If you are a California business owner, here is the headline: you generally cannot stop your employees from leaving and working for a competitor by making them sign a non-compete. California has banned employee non-competes for more than 150 years, and recent legislation has made that ban stronger and sharper. Trying to use a non-compete anyway is not just ineffective, it can now expose you to liability. The better path is to understand what is actually prohibited, what narrowly survives, and how to protect your business through the tools California does allow. Because this area has been changing and is still being tested in court, confirm the current state of the law before relying on any specific point.

The core rule: non-competes are void in California

California’s foundational rule lives in Business and Professions Code section 16600, which voids contracts that restrain someone from engaging in a lawful profession, trade, or business. For over a century, California courts have read this to prohibit employee non-compete agreements. Unlike most states, California does not ask whether a non-compete is “reasonable” in scope or duration, the analysis other states use. In California, an employee non-compete is generally simply void, no matter how narrowly it is written.

The policy behind this is deliberate. California has decided that employee mobility and open competition, people being free to take a better job or start their own venture, are worth more than letting employers lock in their workforce. That choice is widely credited as part of what makes the state’s labor market so dynamic. Whatever one thinks of it, it is the law, and it is unusually strong.

Recent laws made the ban even stronger

Two laws that took effect at the start of 2024 added real teeth to the existing ban. They matter to every California employer.

The first made it expressly unlawful to include a non-compete clause in an employment agreement, not just unenforceable, but unlawful to impose in the first place, unless it fits a recognized exception. It also required employers to notify employees (and certain former employees) that any non-compete they had signed was void, a one-time notice obligation with an early-2024 deadline that has since passed.

The second extended the ban’s reach across state lines. It provides that a non-compete that is void under California law is unenforceable regardless of where or when it was signed, and it bars employers from trying to enforce such agreements against California workers. It also created a private right of action: an employee, former employee, or even a prospective employee can sue an employer that requires or tries to enforce an unlawful non-compete, and can recover damages and attorney’s fees.

Put together, these changes flipped the risk. A non-compete used to be merely a clause a California court would not enforce. Now, requiring one can itself be a violation that hands the employee a lawsuit. For employers, that is a significant shift, the downside of using a non-compete is no longer just “it won’t work,” it is “it could be used against us.”

One wrinkle: the out-of-state enforcement question

There is an unsettled area worth flagging honestly, because it has played out in real cases. While California law says a void non-compete is unenforceable regardless of where it was signed, courts in other states do not always defer to California’s policy. In a closely watched dispute, a court outside California enforced an out-of-state non-compete under that other state’s law against an executive who had moved to California, declining to let California’s ban override the parties’ chosen out-of-state law. The lesson is not that California’s ban is weak, within California it is very strong, but that cross-border situations involving other states’ courts and choice-of-law clauses can produce messier outcomes than the statute alone suggests. If your situation spans multiple states, this is precisely the kind of nuance worth professional advice rather than assumptions.

The narrow exceptions that survive

California’s ban is broad but not absolute. A few statutory exceptions allow properly drafted non-competes in specific, limited circumstances, chiefly:

• Sale of a business. When someone sells their business (or their ownership interest and its goodwill), the buyer can generally obtain a non-compete from the seller within defined limits. This protects the buyer from the seller turning around and immediately competing against the very business they just sold.
• Dissolution of a partnership or an LLC. In connection with dissolving a partnership, or the dissolution or dissociation of an LLC, the owners can agree to certain non-compete terms.

These exceptions are narrow and have specific requirements, and they exist because the rationale is different from the employment context, here, the non-compete protects the value of a deal the restrained person was paid for, rather than locking in an employee. If you are buying or selling a business, a non-compete may well be appropriate and enforceable, but it has to be structured to fit the exception, which is a job for careful drafting.

What about non-solicitation agreements?

Owners often ask whether they can at least stop a departing employee from soliciting the company’s customers or employees, since that feels narrower than a full non-compete. The answer is increasingly cautious.

Agreements barring a former employee from soliciting the company’s customers have generally been treated as void in California, on the view that they restrain the former employee’s trade much like a non-compete. The status of agreements barring solicitation of the company’s employees is less settled: for years some were thought enforceable, but more recent California court decisions have treated broad employee-non-solicitation provisions as void restraints as well, and the recent legislation arguably reinforces that direction. The honest summary is that non-solicitation provisions, especially broad ones, are on increasingly shaky ground in California and should not be relied on as a substitute for a non-compete. This is an unsettled, evolving area, so any reliance on a non-solicit deserves current legal advice.

How to actually protect your business

If you cannot use non-competes, how do you protect what matters, your confidential information, your customer relationships, your investment in employees? California leaves you real tools; they are just different ones:

• Trade-secret protection. This is the big one. California law lets you protect genuinely confidential, competitively valuable information, customer data, processes, formulas, and the like, against misappropriation, provided you actually take steps to keep it secret. A departing employee remains barred from stealing or using your trade secrets even though they are free to compete with you generally.
• Confidentiality and nondisclosure agreements. Properly drafted confidentiality agreements protect your sensitive information without functioning as prohibited non-competes. They are a cornerstone of protecting a California business.
• Strong onboarding and offboarding practices. Limiting access to sensitive information, marking it confidential, and handling departures carefully all reinforce your trade-secret protection.
• In-term duties. While employed, employees owe duties that restrict competing against their employer; the prohibition is on post-employment restraints.

In other words, California’s framework says you cannot stop people from leaving and competing, but you can stop them from taking your secrets with them. Building your protection around trade-secret and confidentiality tools, rather than around an unenforceable and now-risky non-compete, is the right strategy.

Getting these protections drafted correctly, so they protect you without crossing into prohibited territory, is exactly where legal help pays off.

The bottom line

In California, employee non-competes are largely void, and recent laws have made imposing one not just futile but potentially actionable. Narrow exceptions survive mainly for the sale of a business and the dissolution of a partnership or LLC, and non-solicitation provisions occupy uncertain, increasingly unfriendly ground. The practical path for a California business is to stop relying on non-competes and build protection through trade-secret law and well-drafted confidentiality agreements. Because this area is still evolving in the courts, it is worth reviewing your agreements with counsel to make sure they protect you without creating new liability.

Frequently Asked Questions

Are non-compete agreements enforceable in California?

Generally no. In the employment context, California broadly voids non-compete agreements under Business and Professions Code section 16600, regardless of how narrowly they are drafted. Recent laws went further, making it unlawful to even require a non-compete and giving employees the right to sue. Narrow exceptions exist mainly for the sale of a business and the dissolution of a partnership or LLC.

How does California’s ban on non-competes affect business acquisitions and partnerships?

The sale-of-a-business and partnership/LLC-dissolution exceptions mean a properly structured non-compete can be enforceable in those specific contexts, for example, preventing the seller of a business from immediately competing against the buyer. These exceptions are narrow and have specific requirements, so such agreements must be carefully drafted to fit.

What is a non-solicitation agreement and is it valid in California?

A non-solicitation agreement tries to stop a former employee from soliciting the company’s customers or employees. In California, customer non-solicitation provisions have generally been treated as void, and courts have increasingly treated broad employee-non-solicitation provisions as void restraints as well. This is an unsettled, evolving area, so non-solicits should not be relied on as a substitute for a non-compete without current legal advice.

Can California employers protect trade secrets without a non-compete?

Yes. California law lets employers protect genuinely confidential, competitively valuable information against misappropriation, provided they take real steps to keep it secret. Combined with well-drafted confidentiality agreements and careful information practices, trade-secret protection lets employers guard their sensitive information even though employees are free to compete generally.

What recent California laws have changed the rules around restrictive covenants?

Two laws effective at the start of 2024 strengthened California’s existing ban: one made it unlawful to include a non-compete and required notice to affected employees; the other extended the ban to agreements signed out of state and created a private right of action allowing employees to sue for damages and attorney’s fees. Together they turned using a non-compete from merely unenforceable into potentially actionable.
