Jessica JohnsonOn January 1, 2024, two California laws profoundly transformed the state's employment law: AB 1076 and SB 699. These laws codified the unenforceability of non-compete clauses and created a private right of action for employees whose employers attempt to enforce them. For any employee in California—whether they signed their clause yesterday or ten years ago, in this state or another—the legal reality is the same: this clause is, in almost all cases, null and void from the moment of signing.
Article 16600 of the Business and Professions Code: The Foundational Principle
California Business and Professions Code (B&P Code) Section 16600 clearly states that "every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void." This text, in effect since 1872, embodies a fundamental public policy: the free movement of workers and economic competition must not be hindered by private contractual clauses.
The California Supreme Court confirmed this extensive interpretation in Edwards v. Arthur Andersen LLP (2008), rejecting any "reasonable" interpretation of restrictive clauses. The court established that Section 16600 protects the absolute right of employees to practice their profession — and not a balance between employer and employee interests.
Key Takeaway: A non-compete clause that is void in California is not merely unenforceable in court. It is null ab initio — as if it never existed. An employer cannot use it as leverage to dissuade an employee from changing jobs.
California thus radically distinguishes itself from other U.S. states like Texas or Florida, where clauses deemed "reasonable" in duration and geographical scope can be validated by courts. In California, the duration and geographical area of the clause are irrelevant: the restriction itself is void.
AB 1076 and SB 699: New Obligations Since January 1, 2024
AB 1076, effective January 1, 2024, explicitly codifies the Edwards precedent and extends the prohibition to client non-solicitation clauses that, in practice, constitute restrictions on competition. It also imposed a notification obligation on employers: by February 14, 2024, they were required to inform in writing all employees hired after January 1, 2022, of the invalidity of any non-compete clause in their contract.
SB 699, also effective January 1, 2024, goes even further by creating a regime of explicit penalties:
- It prohibits employers from entering into or attempting to enforce void non-compete clauses, even if they were signed in another U.S. state.
- It creates a private right of action: an employee can sue their employer to obtain an injunction, compensatory damages, and reimbursement of their attorney's fees (attorney's fees).
- It applies retroactively to contracts entered into before its effective date.
In practice, if your current or former employer attempts to prevent you from working for a competitor — whether you signed that contract in California or in any other state — you now have a civil right of action based on SB 699, codified in Business and Professions Code (B&P Code) Section 16600.5.
Legal Exceptions: When a Non-Compete Clause Remains Valid
The prohibition in Section 16600 has three statutory exceptions, strictly interpreted by California courts. These exceptions never apply to ordinary employees — they exclusively target situations of sale or dissolution of a business entity where the partner or founder sells goodwill (goodwill).
| Legal Exception | Legal Basis | Required Conditions |
|---|---|---|
| Sale of Business | B&P Code §16601 | Sale of a business's goodwill or assets; the buyer may require the seller not to compete in the ceded area and industry |
| Dissolution of Partnership | B&P Code §16602 | A partner withdraws or the partnership is dissolved; the restriction is limited to the industry and geographical area of activity |
| Dissolution of LLC | B&P Code §16602.5 | Same principle as §16602, applicable to members of a limited liability company upon its dissolution or a member's departure |
These exceptions are restrictively interpreted by California judges. They apply only to founders and partners who sell their shares or liquidate their structure — not to senior executives, employed managers, or ordinary employees, regardless of their seniority or level of responsibility.
Key Takeaway: If you are an employee — even a senior executive — and not a founding partner or owner selling your business, none of these exceptions apply to you. Your non-compete clause is void, without the need to challenge it in court.
Client and Employee Non-Solicitation: A Clarified Gray Area
Before 2024, a distinction existed in case law between non-compete clauses — clearly void — and client or employee non-solicitation clauses, whose status was more ambiguous. Some employers attempted to circumvent Section 16600 by using these contractual variants.
Client Non-Solicitation Clauses
AB 1076 largely clarified the situation. A client non-solicitation clause is now considered void if, in practice, it constitutes a restriction on the exercise of a professional activity. The criterion is functional: does the clause effectively prevent the employee from working with clients of their former employer in their field of activity? If so, it falls under Section 16600.
Employee Non-Solicitation Clauses
Employee non-solicitation clauses remain more complex. A clause that would prohibit an employee from actively recruiting former colleagues can be valid if it is strictly limited and does not constitute a disguised restriction on employment. Post-2024 case law is still consolidating on this point, and California courts examine these clauses on a case-by-case basis.

Trade Secrets and Confidentiality: What Remains Enforceable
The invalidity of non-compete clauses does not leave employers without protection in California. Two distinct mechanisms remain fully applicable and constitute legitimate tools for protecting commercial interests.
Confidentiality Agreements (*Non-Disclosure Agreements*)
A non-disclosure agreement (NDA) obligates the employee not to disclose confidential company information: customer databases, formulas, source codes, business strategies, expansion plans. These agreements are valid in California provided they do not constitute a disguised restriction on employment. In other words, an NDA can prohibit you from disclosing information — it cannot prohibit you from working for a competitor.
Trade Secrets Law: Uniform Trade Secrets Act
California adopted the Uniform Trade Secrets Act (UTSA), codified in Sections 3426 et seq. of the state's Civil Code. This law protects information that meets two conditions: it must have actual or potential economic value due to its secret nature, and its owner must have taken reasonable measures to protect it.
An employee who takes trade secrets when leaving their position can be subject to prosecution under the UTSA — independently of any contractual clause. Protection stems from the law itself, not the contract. In 2023, proceedings related to trade secret theft represented one of the primary labor disputes before federal courts in the Northern District of California [Administrative Office of the U.S. Courts, 2023].
What to Do If Your Employer Invokes a Non-Compete Clause?
Mehdi is a software engineer in San Jose. Two weeks after joining a competing startup, he receives a letter from his former employer warning him that he is "violating his non-compete clause" and threatening legal action. After consulting an employment law attorney, Mehdi discovers that the clause falls entirely under Section 16600, and that the attempt to enforce this clause itself constitutes a violation of SB 699. The employer drops its threats.
This scenario is common. Here's what to do if you find yourself in a similar situation:
Do not sign any new documents without legal consultation. If the employer asks you to confirm, modify, or renew a non-compete clause, first consult a California employment law attorney.
Check if one of the three legal exceptions applies. If you are not a business seller or a departing partner from a partnership or LLC, no exception applies to you (§16601, §16602, §16602.5).
Keep all communications. Retain emails, cease and desist letters, and any written record of attempts to enforce the clause. These elements constitute your proof in case of legal action based on SB 699.
Report the violation to an attorney. Since SB 699, an attempt to enforce a void clause is itself an illegal act giving rise to an injunction, damages, and reimbursement of your attorney's fees.
Contact the California Labor Commissioner's Office. The California Department of Industrial Relations (DIR — Department of Industrial Relations) can direct you to appropriate resources and, in some cases, intervene directly.
Do not be intimidated. Many employers continue to insert non-compete clauses, banking on the fact that employees do not know their rights. The threat of legal action has no legal value if the clause is null ab initio.
What Employers Need to Know to Remain Compliant
For employers, AB 1076 and SB 699 have created new compliance obligations, the non-observance of which exposes them to significant civil penalties. Here are the essential points to master.
Retrospective Notification Obligation
AB 1076 had imposed written notification by February 14, 2024, for all employees hired after January 1, 2022, who had signed a non-compete clause. If your company has not complied with this obligation, the legal risks are real: affected employees have an additional basis for damages actions.
Legitimate Alternatives to Protect Your Interests
California employers can legitimately protect their business interests through:
- Well-drafted confidentiality agreements (NDAs), targeting specific and confidential information.
- Protection of trade secrets via the UTSA, provided reasonable protective measures have been implemented (document marking, restricted access, employee training).
- Narrowly defined employee non-solicitation clauses, if they do not constitute a disguised restriction on employment.
- Intellectual Property Assignment Agreements (IP Assignment Agreements) ensuring that innovations developed within the scope of employment remain the property of the company.
A non-compete clause drafted after 2024 in a California employment contract directly exposes the employer to lawsuits based on SB 699 — independently of any attempt to enforce that clause.
Frequently Asked Questions About Non-Compete Clauses in California
Are non-compete clauses ever valid in California?
Yes, but only in three specific cases defined by law: during the sale of a business (B&P Code §16601), during the dissolution of a partnership (§16602), or during the dissolution of an LLC (§16602.5). For ordinary employees, they are void without exception, regardless of their duration, geographical area, or wording.
What is Business and Professions Code Section 16600?
California Business and Professions Code (B&P Code) Section 16600 declares void any contractual clause restricting the exercise of a lawful profession, trade, or business. It is the legal basis for the prohibition of non-compete clauses in the state, effective since 1872.
Can my employer force me to sign a non-compete clause?
An employer can ask you to sign such a clause, but it will be null and unenforceable. Since SB 699 (2024), attempting to enforce a void clause is itself illegal and exposes the employer to civil lawsuits.
I signed a non-compete clause in another state — is it valid if I work in California?
No. SB 699 explicitly applies to clauses signed outside of California. If you work in California, your clause is void, regardless of the state in which it was drafted or signed.
What is the difference between a non-compete clause and a confidentiality agreement?
A non-compete clause prohibits you from working for competitors — it is void in California. A confidentiality agreement (NDA) prohibits you from disclosing confidential information or trade secrets. The NDA is generally valid and enforceable, provided it does not constitute a disguised restriction on employment.
