Quick Answer
Official text of California Business & Professions Code 16600 and SB 699: why non-compete agreements are void in California and what to do if your employer tries to enforce one.
If your California employer asked you to sign a non-compete agreement, here's what you need to know: the contract is almost certainly void and unenforceable. California law takes a clear stance against non-compete clauses that prevent workers from earning a living in their profession or trade.
This guide explains why California bans non-compete agreements, what the law says, the rare exceptions that do exist, and what you should do if your employer tries to enforce one against you.
Why California Bans Non-Compete Agreements
California's approach to non-competes is uniquely protective of workers and competition. The state has decided that the benefits of allowing people to work freely outweigh any harm that might come from employees taking business knowledge elsewhere.
The Core Law: Business & Professions Code § 16600
California's main statute on this issue is straightforward. Business & Professions Code § 16600 states:
"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 language is intentionally broad. It doesn't say "unreasonable" non-competes are void. It doesn't allow for "narrow restraints." The law simply says that any contract preventing someone from working in their profession is void.
What Non-Competes Actually Do
A non-compete agreement typically tries to prevent you from working for a competitor or starting a competing business for a set period (often 6 months to 2 years) after leaving your employer.
For example, a non-compete might say: "You cannot work for any competitor of Company X within 50 miles for 18 months after you leave."
These agreements create a problem. They don't just protect an employer's legitimate business interests (like trade secrets). They also prevent workers from using their skills and experience to earn a living. This harms the worker and reduces healthy competition in the marketplace.
California decided long ago that this tradeoff isn't worth it.
The Edwards v. Arthur Andersen Decision
The California Supreme Court clarified this position in a landmark case that settled the debate over so-called "narrow restraints."
The Case Background
Raymond Edwards worked for Arthur Andersen, the accounting firm, as a tax manager. When he was hired in 1997, Arthur Andersen required him to sign a non-compete agreement. The agreement barred Edwards from performing the same professional services for any of Arthur Andersen's clients for 18 months after leaving.
This wasn't a broad, nationwide restriction. It was limited to Arthur Andersen's clients and lasted only 18 months. It seemed reasonable and narrow on its face.
When Edwards left the firm, Arthur Andersen tried to enforce the agreement. Edwards challenged it in court.
The Supreme Court's Ruling (2008)
The California Supreme Court ruled unanimously that the agreement was void under § 16600—even though it was narrowly tailored.
The court rejected the idea that California law allows an exception for "narrow restraints" on competition. Federal courts (particularly in the Ninth Circuit) had previously suggested such an exception might exist. California's highest court said no.
The reasoning was simple: If the Legislature wanted to allow "reasonable" or "narrow" non-competes, it could have said so. The statute makes no such distinction. It says all contracts restraining someone from engaging in their profession are void.
Why This Matters
Edwards v. Arthur Andersen means that no matter how reasonably written or narrowly tailored your non-compete is, California courts will not enforce it. A non-compete limited to:
- A small geographic area
- A short time period
- Specific competitors or clients
...is still void.
This clarity benefits California workers and employers who compete fairly rather than through restrictive covenants.
Recent Strengthening: Senate Bill 699 (2023)
California strengthened its non-compete ban even further in 2023 with Senate Bill 699, which Governor Newsom signed into law on September 1, 2023.
What SB 699 Added
Extraterritorial Reach: The new law makes clear that non-compete agreements are void under California law regardless of where you worked when you signed the agreement or where the agreement says it applies. If you're a California resident or worked in California, the law protects you even if the non-compete says it's governed by another state's law.
Prohibition on Attempts to Enforce: Employers are not only prohibited from enforcing non-competes—they're also barred from "attempting to enforce" them. This means threatening legal action or sending cease-and-desist letters about a non-compete violates the law.
Private Right of Action: If an employer tries to enforce or threatens to enforce a void non-compete against you, you can sue for:
- Injunctive relief (a court order stopping the action)
- Actual damages (money you lost)
- Attorney's fees and court costs
The February 2024 Notification Requirement
SB 699 included another provision: employers were required to notify all California employees by February 14, 2024, that any non-compete agreements they signed are void and unenforceable.
Many California employers missed this deadline or provided inadequate notice. If your employer tried to collect signatures saying they'd comply with this requirement or failed to notify you entirely, that's another violation of the law.
The Rare Exceptions: When Non-Compete-Like Restrictions Do Apply
While non-competes are essentially always void for employees, California law does allow two narrow exceptions related to business transactions.
Exception 1: Sale of a Business (B&P Code § 16601)
Under California Business & Professions Code § 16601, a person who sells the goodwill of a business, or sells substantially all of its operating assets and goodwill, or who sells all of the ownership interest in a business entity, may agree with the buyer to refrain from carrying on a similar business within a specified geographic area in which the business was sold — so long as the buyer or any person deriving title from the buyer carries on a like business there.
This is the principal statutory exception to § 16600. It applies to owners selling a business, not to rank-and-file employees of that business.
When someone sells their entire business or sells substantially all of the assets of a business, the buyer can require the seller not to compete for a reasonable period in the same geographic area.
Important: This exception applies to people selling a business, not to employees of that business. If you're sold along with your employer's business, you generally still can't be bound by a non-compete.
Exception 2: Dissolution of a Partnership or Limited Liability Company
When a partnership dissolves or a member of an LLC leaves, the partnership or LLC can include non-compete provisions in the departure agreement—but only if the non-compete is limited to the partnership's or LLC's geographic area and clients.
This exception makes sense because partners and LLC members have different legal status than employees. They're partial owners, not workers.
What About Non-Solicitation Agreements?
Non-compete agreements are different from non-solicitation agreements. A non-solicitation agreement says you can't solicit your former employer's customers or employees, typically for a limited period.
California courts sometimes enforce narrow non-solicitation agreements focused on legitimate business interests like trade secrets or confidential information. These are treated more favorably than non-competes because they don't prevent you from working entirely—they just limit who you can work with.
If you have a non-solicitation agreement, you're in a different legal situation than someone with a non-compete. Learn more in our guide to non-solicitation agreements in California.
What to Do If Your Employer Tries to Enforce a Non-Compete
If your employer has told you that you can't work elsewhere, sent a cease-and-desist letter, threatened legal action, or attempted to enforce a non-compete in any way, here are your options.
Document Everything
Keep records of:
- The original non-compete agreement
- Any communications about enforcing it (emails, letters, phone call notes)
- Dates and details of what happened
- Any impact on your job prospects or income
Understand Your Leverage
Your employer is already violating California law by trying to enforce a void agreement. This is a significant legal problem for them. Many employers don't realize this and back off immediately when confronted with the law.
Send a Clear Response
Consider having an attorney send a letter stating:
- The non-compete is void under Business & Professions Code § 16600
- SB 699 makes it illegal to attempt to enforce it
- You expect the employer to cease all enforcement efforts
- You reserve the right to pursue legal remedies if they continue
Many employers stop when they receive this letter.
File a Complaint with the State
You can file a complaint with the California Labor Commissioner about your employer's violation of SB 699. The Labor Commissioner's office can investigate and take action.
Sue for Damages and Attorney's Fees
If your employer continues to pursue enforcement despite knowing the law, or if their actions damaged you financially or professionally, you can sue under SB 699. You're entitled to actual damages and, importantly, attorney's fees.
The attorney's fees provision is crucial. It means you might be able to pursue your claim with an attorney on a contingency basis, even if your actual damages aren't large.
Defend Yourself If Sued
If your employer files a lawsuit to enforce the non-compete, your attorney should immediately move to dismiss the case, citing § 16600 and Edwards v. Arthur Andersen. Courts routinely dismiss non-compete cases at early stages.
Key Takeaways
Non-compete agreements are void in California. This rule applies regardless of:
- How narrowly written the agreement is
- How reasonable it might seem
- Where the agreement was signed or says it applies
- What other states' laws it references
SB 699 strengthened the ban by making it illegal to attempt to enforce non-competes and creating a private right of action if an employer tries.
Rare exceptions exist for the sale of an entire business and dissolution of partnerships or LLCs—but these don't protect employees.
You have rights if your employer tries to enforce a non-compete. You can seek legal remedies, recover damages, and obtain attorney's fees.
If you're facing a non-compete enforcement situation, consult with an employment law attorney. The vast majority of these cases are resolved quickly once an employer understands that California law provides no protection for such agreements.
Frequently Asked Questions About Non-Competes in California
Are non-compete agreements enforceable in California?
No. California Business & Professions Code § 16600 makes non-compete agreements void and unenforceable. This applies to all non-competes regardless of how narrowly written they are. The California Supreme Court confirmed this in Edwards v. Arthur Andersen (2008), ruling that even "reasonable" or "narrow" non-competes are void.
What does California Business & Professions Code 16600 say?
Section 16600 states: "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 makes all employee non-compete agreements unenforceable in California, regardless of geographic scope, duration, or how the agreement is worded.
Can my employer sue me for violating a non-compete in California?
Your employer cannot successfully sue you for violating a non-compete in California because the agreement is void under § 16600. Courts routinely dismiss such cases at early stages. Under SB 699 (effective 2024), you can actually sue your employer if they attempt to enforce a non-compete against you, recovering damages and attorney's fees.
What is SB 699 and how does it affect non-competes?
SB 699 (2023) strengthened California's non-compete ban in several ways: it made clear the ban applies regardless of where the agreement was signed, it prohibits employers from even attempting to enforce non-competes, and it creates a private right of action allowing employees to sue for damages and attorney's fees if employers try to enforce void agreements. Employers were also required to notify employees by February 14, 2024, that any non-competes they signed are void.
Are there any exceptions to California's non-compete ban?
The only exceptions are for: (1) sale of a business, where the buyer can require the seller not to compete in the same geographic area for a reasonable period, and (2) dissolution of a partnership or LLC, where departing partners may have limited geographic and client restrictions. These exceptions do not apply to regular employees—only to business owners selling their companies or partners leaving partnerships.
