Non-Solicitation Agreements in California: What Can Businesses Actually Enforce?

California non-solicitation agreements face significant restrictions. Learn how employers can protect trade secrets without overreaching. The appropriate course depends on the agreements, the parties, and the facts. Below are the issues worth reviewing before making a consequential decision.

California takes a restrictive approach

California Business and Professions Code section 16600 broadly invalidates contracts that restrain a person from engaging in a lawful profession, trade, or business, subject to statutory exceptions. Recent statutory amendments emphasize this policy in the employment context. Businesses should not assume a narrowly worded restriction will be enforceable simply because it is called a non-solicitation clause rather than a noncompete.

Customer non-solicitation provisions

A clause prohibiting a departing employee from approaching former customers may restrain competition and face serious enforceability problems under California law. The precise analysis depends on the relationship, the contract, the facts, and any applicable statutory exception. A provision should not be treated as valid merely because it lasts six or twelve months.

Employee non-solicitation provisions

Restrictions on recruiting or hiring former colleagues also require careful analysis. California decisions have questioned the enforceability of employee non-solicitation clauses, particularly where they restrain lawful employment opportunities. Businesses should obtain California-specific advice instead of importing a form agreement written for another state.

Protect confidential information lawfully

California law can protect qualifying trade secrets and confidential business information. Businesses can use carefully drafted confidentiality obligations, reasonable access controls, offboarding procedures, and documented information-security practices. Those protections should target misuse of protected information rather than prohibit ordinary competition or the use of general professional skills.

Special contexts and exceptions

Certain restrictions connected to the sale of a business, ownership interests, or dissolution arrangements may qualify for statutory exceptions when the requirements are satisfied. Those exceptions should not be stretched to cover routine employment agreements. Choice-of-law and forum provisions also deserve review when a California worker is involved.

What to do when someone leaves

Preserve relevant records, promptly disable access, recover company devices, and remind the individual of lawful confidentiality duties. Before sending a cease-and-desist letter, identify the specific information allegedly taken or misused and the factual basis for the claim. Unsupported accusations can increase costs and exposure.

Frequently asked questions

Are all non-solicitation clauses void in California? No single answer fits every context, but employment-related restraints face significant restrictions. Can a former employee compete? Generally, lawful competition is protected, while misappropriation of trade secrets is not. Can I copy another state's form? That is risky.
