Non-Compete Agreement Law in California
No. In California, non-compete agreements in employment contracts are void and unenforceable in almost all cases. California law voids all non-compete agreements in employment, regardless of how narrowly they are written or what consideration was paid. Only narrow exceptions for business sales, partnership dissolutions, and LLC member withdrawals permit any post-employment restraints on competition.
Are non-compete agreements enforceable in California?
No. In California, non-compete agreements in employment contracts are void and unenforceable in almost all cases. Business and Professions Code § 16600(a) voids "every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind." The 2024 amendments codified Edwards v. Arthur Andersen LLP, 44 Cal.4th 937 (2008), directing that the statute be read broadly "to void the application of any noncompete agreement in an employment context, or any noncompete clause in an employment contract, no matter how narrowly tailored" (Bus. & Prof. Code § 16600(b)(1)).
What should I do if my employer asks me to sign a non-compete?
You can refuse, and they cannot require it as a condition of employment. If they retaliate, you may have claims. It is unlawful for an employer to include a non-compete clause in an employment contract or to require an employee to enter a non-compete agreement that does not satisfy a statutory exception (Bus. & Prof. Code § 16600.1(a)). Labor Code § 432.5 also prohibits an employer from requiring any employee to agree, in writing, to any term known to be prohibited by law.
| If your employer... | You can... | Legal basis |
|---|---|---|
| Asks you to sign a non-compete | Refuse to sign; the agreement is void | Bus. & Prof. Code § 16600(a) |
| Makes signing a condition of employment | Refuse; this is unlawful | Bus. & Prof. Code § 16600.1(a) |
| Retaliates for your refusal | Potentially bring claims for retaliation | |
| Includes a non-compete in your contract | Treat it as void; you have a private right of action | Bus. & Prof. Code § 16600.5(e) |
Can my employer sue me for working for a competitor?
They can file suit, but you can defend and recover attorney's fees; the agreement is void so they cannot win. An employer or former employer is prohibited from attempting to enforce a void non-compete contract regardless of where it was signed or where employment occurred (Bus. & Prof. Code § 16600.5(b)). If they sue, you have a private right of action to enforce the voidness, seek injunctive relief, recover actual damages, and recover reasonable attorney's fees and costs (Bus. & Prof. Code § 16600.5(e)).
I signed a non-compete before 2024 — is it still valid?
Yes, it is void. The 2024 law was declaratory of existing law per Business and Professions Code § 16600(b)(2). The amendments codified the California Supreme Court's holding in Edwards v. Arthur Andersen LLP, 44 Cal.4th 937 (2008), meaning the near-absolute prohibition on employment non-competes was already the law.
When can a non-compete ever be valid in California?
Non-competes are only valid within three narrow statutory exceptions. For agreements that do qualify, the contract must track statutory requirements precisely:
| Exception | Required Elements |
|---|---|
| Sale of business (Bus. & Prof. Code § 16601) | Sale of goodwill, all ownership interest, or substantially all operating assets; specified geographic area where business was carried on; restraint lasts only so long as buyer continues "like business" |
| Partnership dissolution (Bus. & Prof. Code § 16602) | Dissolution or dissociation; specified geographic area where partnership operated; restraint lasts only so long as remaining partner continues "like business" |
| LLC member withdrawal (Bus. & Prof. Code § 16602.5) | Dissolution or termination of membership interest; specified geographic area where LLC operated; restraint lasts only so long as remaining member continues "like business" |
Critical limitation: These exceptions apply only to the specific transactional contexts described. They do not create a general enforceability standard for employment non-competes.
What non-compete agreements are illegal in California?
California law prohibits far more than it permits. The following are expressly barred:
Unlawful Inclusion and Enforcement
| Prohibited Conduct | Statutory Basis |
|---|---|
| Including a non-compete clause in an employment contract | Bus. & Prof. Code § 16600.1(a) |
| Requiring an employee to enter a non-compete agreement | Bus. & Prof. Code § 16600.1(a) |
| Attempting to enforce a void non-compete, regardless of where signed or where employment occurred | Bus. & Prof. Code § 16600.5(b) |
| Entering a contract containing a void non-compete provision | Bus. & Prof. Code § 16600.5(c) |
Violation constitutes an act of unfair competition (Bus. & Prof. Code § 16600.1(c)) and a civil violation (Bus. & Prof. Code § 16600.5(d)).
Choice-of-Law and Forum Selection Restrictions
Labor Code § 925 prohibits employers from requiring California-resident employees to: - Adjudicate disputes outside California (including arbitration) - Waive the substantive protection of California law
These provisions are voidable at the employee's request, with mandatory California adjudication and law to follow (Labor Code § 925(b)). The sole exception: employees "in fact individually represented by legal counsel in negotiating" these specific terms (Labor Code § 925(e)).
When will California courts enforce any non-compete restriction?
No Reasonableness Analysis for Employment
California rejects the common law "rule of reason" that governs non-competes in most states. Courts do not weigh the employer's legitimate business interest against hardship to the employee. Employment non-competes are void per se unless they satisfy a statutory exception (Bus. & Prof. Code § 16600(b)(1)).
Consideration Cannot Validate Void Agreements
No amount of consideration—whether initial employment, continued employment, or additional compensation—can validate a non-compete that lacks a statutory exception. The agreement is void from inception.
Judicial Modification: Unclear Status
Whether California courts may "blue-pencil" (sever) or reform overbroad non-compete clauses, rather than strike them entirely, could not be confirmed in available research. Given the statutory directive that non-competes are void "no matter how narrowly tailored," judicial reformation appears inconsistent with the legislative scheme.
Trade Secret and Confidentiality Protections
California protects trade secrets under the Uniform Trade Secrets Act (Civ. Code §§ 3426 et seq.). However, whether trade secret protection can support injunctive relief functionally equivalent to a non-compete—through "inevitable disclosure" doctrine or otherwise—remains unresolved in available materials.
The enforceability of employee and customer non-solicitation agreements as alternatives to non-competes is also not established in the research materials. Because these rules depend on your specific job duties and the information you accessed, Ask Sawyer researches federal and California law to answer questions about your facts.
How is California non-compete law different from other states?
California departs from the national baseline more dramatically than any other state:
| Aspect | National Baseline | California |
|---|---|---|
| Standard of review | Rule of reason: courts weigh employer interest, employee hardship, and public injury | Per se void: non-competes void regardless of reasonableness, consideration, or narrow tailoring |
| Protected interests | Common law protected interests (exemplified by Florida statute) | Statutory exceptions only: sale of business, partnership dissolution, LLC withdrawal |
| Geographic scope | Generally subject to reasonableness review, though specific standards vary significantly by state | Irrelevant to enforceability in employment context |
| Duration | Generally subject to reasonableness review, though specific caps vary by state | Irrelevant to enforceability in employment context |
| Consideration | May validate post-employment restrictions | Cannot validate void employment non-compete |
| Choice-of-law | Generally enforceable subject to conflict analysis | Mandatory California law for California-resident employees; foreign forum provisions voidable |
| Enforcement mechanism | Employer-initiated breach actions | Private right of action for employees with mandatory fee-shifting |
| Extraterritoriality | Out-of-state employers may enforce valid home-state non-competes | Express prohibition on enforcement regardless of signing location or place of employment |
Common Pitfalls: Clauses That Won't Hold Up
Including Any Employment Non-Compete
Even a one-month, city-wide non-compete for a narrow job function is void if it does not satisfy a statutory exception. The 2024 amendments make inclusion itself an unfair competition violation and attempted enforcement a civil violation.
Relying on Out-of-State Law
Choice-of-law clauses selecting the law of a permissive state (such as Florida or Texas) are ineffective against California employees.
Using Non-Solicitation as a Substitute
Employee and customer non-solicitation agreements are frequently used as alternatives to non-competes in other states. Whether these constitute prohibited restraints on "engaging in a lawful profession, trade, or business" under California law remains unresolved. Do not assume these provisions are enforceable substitutes.
Overbroad Confidentiality Provisions
Confidentiality agreements that define "confidential information" so broadly as to prevent all competitive activity may be challenged as disguised non-competes and struck as void.
Post-2024 Noncompliance
Employers with pre-2024 agreements must recognize that new statutory prohibitions on entry into and attempted enforcement of void contracts create new exposure.
Whether your specific agreement falls within a statutory exception, or whether alternative protective provisions are available for your situation, requires fact-specific analysis. Ask Sawyer can research how California law applies to your particular employment circumstances.
