California is the outlier state on this question, and it has been for well over a century. The rule is not that noncompetes get narrowed to something reasonable; the rule is that they are void in the employment context. This article covers the governing sections, the notice employers owed in early 2024, how the ban applies to agreements signed elsewhere, and the restrictions that do survive. It sits alongside the rest of the California labor laws reference.
The statute that voids non-competes
The operative text is short. Under Cal. Bus. & Prof. Code § 16600, “every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void,” except as the chapter itself provides.
Subdivision (b)(1) was added effective January 1, 2024. It instructs courts to read the section broadly, in accordance with Edwards v. Arthur Andersen LLP (2008) 44 Cal.4th 937, to void the application of any noncompete agreement in an employment context, or any noncompete clause in an employment contract, no matter how narrowly the restriction is written. The same subdivision reaches restraints that fall short of a total ban on working in the field.
That last point is what separates California from the states that apply a reasonableness test. Elsewhere, a court asks whether the duration, the geography, and the scope of work are proportionate to a legitimate business interest, and it may rewrite an overbroad clause to fit. California courts do not run that analysis in employment cases. A twelve-month, five-mile, single-competitor restriction on a departing employee is void on the same footing as a nationwide lifetime ban.
The ban is not limited to documents titled “noncompete.” A clause that penalizes an employee for going to work for a competitor, forfeits earned compensation on that basis, or conditions a payment on staying out of the field operates as a restraint and is analyzed as one.
What the 2024 amendments added
Two bills took effect on January 1, 2024. The first added the broad-reading language to section 16600. The second created affirmative duties for employers.
Under Cal. Bus. & Prof. Code § 16600.1, it is unlawful to include a noncompete clause in an employment contract, or to require an employee to enter a noncompete agreement, unless the agreement satisfies one of the chapter’s exceptions. Section 16600.1 also imposed a one-time cleanup obligation: for current and former employees employed after January 1, 2022 whose contracts contained a noncompete clause that meets no exception, the employer had to notify the employee by February 14, 2024 that the clause is void.
A violation of section 16600.1 is an act of unfair competition within the meaning of Cal. Bus. & Prof. Code § 17200, which opens the door to the remedies available under the unfair competition law. Employers that missed the deadline remain exposed; the statute set a date, not a window that closed the exposure once it passed.
The three exceptions that survive
The exceptions all involve an ownership stake changing hands, not an employment relationship. They appear in Bus. & Prof. Code §§ 16601–16602.5.
- Sale of a business. Under
Cal. Bus. & Prof. Code § 16601, a person who sells the goodwill of a business, or an owner who disposes of all of an ownership interest, or an owner selling all or substantially all of the operating assets together with the goodwill, can agree not to carry on a similar business within a specified geographic area where the buyer carries on business. - Dissolution of a partnership. A partner may agree, upon or in anticipation of dissolution or of dissociation from the partnership, not to carry on a similar business within a specified area.
- Dissolution of a limited liability company. A member may make the same kind of agreement upon or in anticipation of dissolution of the LLC or termination of the member’s interest in it.
Each exception is tied to a defined geographic area and to a genuine transfer of ownership or goodwill. Handing an employee a small equity grant and calling the departure a “sale” does not convert an employment noncompete into a section 16601 agreement. Courts examine whether real goodwill was actually sold.
Agreements signed in another state
Employers with operations in several states often ask a California-based worker to sign the company’s standard agreement from its home state, sometimes with a clause selecting that state’s law and courts. California addresses both moves.
Cal. Bus. & Prof. Code § 16600.5 provides that a contract void under the chapter is unenforceable regardless of where and when it was signed, and that an employer or former employer may not attempt to enforce such a contract regardless of whether the contract was signed and the employment was maintained outside of California. The section also creates a private action for injunctive relief, actual damages, or both, and a prevailing employee, former employee, or prospective employee is entitled to recover attorney’s fees and costs.
The choice-of-law problem is handled separately. Under Cal. Lab. Code § 925, an employer may not require an employee who primarily resides and works in California, as a condition of employment, to agree to a provision that would litigate a California claim outside California or apply another state’s law to it. A provision that violates section 925 is voidable by the employee, and when the employee voids it, the matter is adjudicated in California under California law. The section applies to contracts entered into, modified, or extended on or after January 1, 2017.
Classification matters here because these protections are written around employees. Whether a worker is an employee or an independent contractor turns on the California ABC test, and section 16600’s general voiding language reaches restraints on contractors as well.
What an employer can still enforce
The ban on noncompetes is not a licence to take an employer’s confidential material out the door.
Trade secret protection is the main survivor. Cal. Civ. Code § 3426.1 defines a trade secret as information that derives independent economic value from not being generally known and is the subject of reasonable efforts to keep it secret. Misappropriating that information is actionable whether or not any agreement was signed, and a confidentiality agreement that protects genuine trade secrets is enforceable.
Other restrictions sit closer to the line. Nondisclosure agreements are valid to the extent they protect confidential information rather than function as disguised restraints on employment. Nonsolicitation-of-customer clauses have fared poorly in California when they operate to keep a former employee out of the market. Employee nonsolicitation clauses have also been struck down in published California appellate decisions applying section 16600. Forfeiture-for-competition provisions in bonus, commission, or equity plans face the same analysis.
An employer that terminates or refuses to hire someone for declining to sign a void noncompete is acting outside the ordinary latitude of at-will employment in California, and the refusal can support a claim for wrongful termination in California in violation of public policy. ## How a worker challenges a non-compete A void agreement is void without any court saying so first, which means most disputes surface when a former employer sends a demand letter or files suit. The path below describes how those disputes typically proceed.
Read the clause and identify its type
Separate a true noncompete from a confidentiality clause, an invention assignment, or a customer nonsolicitation provision. The analysis differs by type, and many agreements contain several of them in the same paragraph. A clause that restricts where a person may work after employment ends is the one section 16600 voids.
Check for an ownership-transfer exception
Look for a sale of goodwill, a disposal of an ownership interest, or a partnership or LLC dissolution. Absent one of those, no exception in the chapter applies to an employment noncompete.
Preserve the notice record
Employers owed a written individualized notice by February 14, 2024 to employees employed after January 1, 2022 whose contracts contained a void clause. Whether that notice arrived, and in what form, is relevant to a section 16600.1 claim.
Respond in writing to any demand
A written response that identifies the governing statute creates a record of when the employer was told the clause is void. Continued enforcement efforts after that point bear on the attempt-to-enforce provision in section 16600.5.
Choose a forum for affirmative relief
Section 16600.5 authorizes a private action for injunctive relief, actual damages, or both, with attorney’s fees for a prevailing worker. Claims small enough to fit the small claims limit of $12,500 for an individual can be filed there; injunctive relief and larger damages claims are filed in the civil divisions of the superior court.
Frequently asked questions
Is a non-compete I signed before 2024 still void?
Section 16600 has voided employment restraints since long before the 2024 amendments; the amendments confirmed the breadth of the rule rather than creating it. The date of signature does not revive a clause that restrains a person from engaging in a lawful profession, trade, or business. Cal. Bus. & Prof. Code § 16600.5 states that a contract void under the chapter is unenforceable regardless of where and when it was signed.
What if my employer never sent the February 2024 notice?
The notice obligation in Cal. Bus. & Prof. Code § 16600.1 applied to employers whose current or former employees, employed after January 1, 2022, had contracts containing a noncompete clause meeting no exception. A violation is an act of unfair competition. The absence of the notice does not make the clause enforceable; the clause was already void.
Can a California employer stop me from soliciting former coworkers?
Employee nonsolicitation clauses have been held void under section 16600 in published California appellate decisions, on the reasoning that they restrain the departing employee’s trade. A separate question is whether the person used the former employer’s confidential contact or compensation data to do the soliciting, which is analyzed as trade secret misappropriation under Cal. Civ. Code § 3426.1 rather than as a contract restraint.
My contract says Texas law applies. Does that change anything?
For a worker who primarily resides and works in California, Cal. Lab. Code § 925 makes a choice-of-law or out-of-state forum provision voidable by the employee when it was required as a condition of employment and entered into, modified, or extended on or after January 1, 2017. When the employee voids it, the dispute is adjudicated in California under California law. Section 16600.5 separately bars enforcement of a void contract regardless of where it was signed.
Does the ban apply to noncompetes tied to equity or bonus plans?
A provision that takes away earned compensation because a person went to work in the same field operates as a restraint and is analyzed under section 16600 rather than treated as a neutral plan term. The label on the document does not control the analysis. Terms tied to the sale of an ownership interest can fall within the exceptions in Bus. & Prof. Code §§ 16601–16602.5 when a genuine transfer of goodwill occurred.
