Quick answer: Non-compete agreements are almost never enforceable in California. Under Business and Professions Code Section 16600, any contract that restrains a person from working in their chosen profession is void. Non-solicitation agreements occupy a grayer area, but California courts have narrowed their enforceability significantly in recent years.
If you’ve just been handed an employment contract with a non-compete clause, or you’re an employer trying to protect your business after a key employee leaves, you’re probably wondering where the law actually stands. California has some of the strongest worker protections in the country on this issue, and understanding the difference between a non-compete and a non-solicitation agreement could save you a costly legal dispute.
At The Mellor Law Firm, we work with both employers and employees navigating these exact situations. Here’s what you need to know.
What Is a Non-Compete Agreement?
A non-compete agreement is a contract that prevents an employee from working for a competing business after leaving their job. These clauses typically restrict where a person can work, who they can work for, and for how long.
Common examples include:- A software engineer at a tech company who is told they cannot join a competing firm for two years after resigning
- A sales manager who signs a clause saying they cannot start a business in the same industry within a 50-mile radius
- A marketing consultant restricted from offering the same services to clients in the same market
These restrictions are common in many U.S. states. In California, they are almost always unenforceable.
Why Are Non-Competes Unenforceable in California?
California Business and Professions Code Section 16600 is direct: “every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void.”
The statute was strengthened by AB 1076, which took effect January 1, 2024. It explicitly states that Section 16600 must be read broadly to void any non-compete agreement in an employment context, regardless of how narrowly it is written. The California Supreme Court reinforced this position in Edwards v. Arthur Andersen LLP (2008) 44 Cal.4th 937, which confirmed that even narrow non-competes are invalid.
So when people ask, “Are non-competes enforceable in California?” the short answer is: almost never.
What Is a Non-Solicitation Agreement?
A non-solicitation agreement is different from a non-compete. Rather than restricting where someone works, it restricts who they can contact after leaving. These agreements typically fall into three categories:
- Customer non-solicitation clauses: Prevent a former employee from reaching out to the company’s clients to take their business elsewhere
- Employee non-solicitation clauses: Prevent a departing employee from recruiting their former colleagues to join a new employer
- Vendor or client relationship clauses: Restrict a former employee from leveraging supplier or partner relationships they built on the company’s behalf
A non-solicitation agreement does not stop you from working for a competitor. It only limits specific outreach to certain people or clients.
Are Non-Solicitation Agreements Enforceable in California?
This is where it gets more complicated. California courts have increasingly scrutinized non-solicitation agreements, and several recent decisions have found that customer non-solicitation clauses function like non-competes and are therefore void under Section 16600.
Employee non-solicitation agreements have faced similar challenges. While the law has not categorically banned them, California courts will look closely at whether a clause genuinely protects a legitimate business interest or simply limits where someone can work.
If you’re an employer relying on a non-solicitation agreement to protect your business, it’s worth getting legal advice before assuming it will hold up in court.
What About Trade Secrets and Confidentiality Agreements?
California law does protect trade secrets and confidential information under the California Uniform Trade Secrets Act (CUTSA). Employers can use confidentiality agreements to prevent employees from sharing proprietary information, client data, business strategies, or technical know-how.
These agreements are distinct from non-competes. A confidentiality agreement does not stop someone from working in the same industry. It simply prevents them from taking specific information with them. Courts in California are far more willing to enforce these protections.
What Should Employers Do Instead of Relying on a Non-Compete?
Given that non-competes are essentially unenforceable in California, employers need smarter strategies to protect their business interests:
- Use strong confidentiality agreements to protect trade secrets, client lists, and proprietary processes
- Implement clear IP assignment clauses so that work created during employment belongs to the company
- Build client relationships at the company level, not just through individual employees
- Offer competitive compensation and culture to reduce the risk of key employees leaving in the first place
- Consult an attorney before drafting employment agreements to ensure your protections are legally sound
Guidance for Employees Asked to Sign These Agreements
If an employer asks you to sign a non-compete in California, you have rights. As of January 1, 2024, employers are required to notify current and former employees if they have non-competes that are now void under the updated law.
Before signing anything, consider the following:
- Ask whether the clause is a non-compete or a non-solicitation agreement
- Get legal advice if you are unsure what you are signing
- Understand that signing a void non-compete does not make it enforceable, but it can create unnecessary stress and legal risk
If a former employer tries to enforce a non-compete against you in California, speaking with an employment attorney quickly is the smartest move.

Frequently Asked Questions
Are non-compete agreements enforceable in California?
No. Under California Business and Professions Code Section 16600, non-compete agreements in an employment context are void. This applies regardless of how narrowly the clause is written, following the 2008 ruling in Edwards v. Arthur Andersen LLP (2008) 44 Cal.4th 937, and the updated statute effective January 1, 2024.
Can my employer stop me from working for a competitor in California?
Generally, no. California law protects your right to work in your chosen profession. An employer cannot legally prevent you from taking a job at a competing company after you leave, even if you signed a non-compete clause.
Is a non-solicitation agreement the same as a non-compete?
No. A non-compete restricts where you can work. A non-solicitation agreement restricts who you can contact, such as former clients or colleagues. However, California courts have found that some non-solicitation clauses function like non-competes and can also be void under Section 16600.
Can a company stop a former employee from taking customers?
California courts have increasingly found that customer non-solicitation clauses are unenforceable when they effectively prevent someone from practicing their profession. Each case depends on specific facts, so legal advice is recommended if you are facing this situation.
Are non-competes enforceable in California when selling a business?
Yes, with limits. Section 16600 includes a narrow exception for the sale of a business. A buyer can require the seller to agree not to compete in certain circumstances tied to the sale. This is one of the few situations where a non-compete can be enforceable in California.
