Navigating California's Non-Compete Ban: Drafting Enforceable Non-Solicit and NDA Clauses (B&P 16600)

California's thriving economy, especially in tech hubs like Silicon Valley and major corporate centers in Los Angeles and San Francisco, is built on the free mobility of talent. Unlike most states, California has maintained a fierce public policy against non-compete agreements. Recent legislative updates, including Senate Bill 699 (Cal. Bus. & Prof. Code § 16600.5) and Assembly Bill 1076 (Cal. Bus. & Prof. Code § 16600.1), have completely weaponized this ban, making it an actionable offense for an employer to even ask an employee to sign a void non-compete clause. These rules even apply to remote workers who signed contracts in other states but have since relocated to California.

For employers, this creates a challenging landscape. How do you stop a departing executive from misappropriating your proprietary client data to launch a rival firm? The answer lies in precision drafting. You must pivot from broad non-competes to enforceable Non-Disclosure Agreements (NDAs) and statutory trade secret protections. If you need to overhaul your employment documents, you can find a dedicated business attorney in our US Lawyer Directory to ensure your contracts do not violate state law.

The Power of Cal. Bus. & Prof. Code § 16600

The core of California's ban is found in Cal. Bus. & Prof. Code § 16600, which states that "every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void." Under Cal. Bus. & Prof. Code § 16600.5, employers who attempt to enforce or enter into void restrictive covenants commit a civil violation, allowing employees to sue for injunctive relief, actual damages, and attorney's fees. Furthermore, the California Office of the Attorney General, Sacramento and city prosecutors can impose civil remedies against companies maintaining unlawful contracts.

Customer Non-Solicits vs. Employee Non-Solicits

Since you cannot ban a former employee from working for a competitor, you might be tempted to restrict them from soliciting your clients or staff. In California, Customer Non-Solicitation clauses in employment contracts are void per se under Cal. Bus. & Prof. Code § 16600, as established by the California Supreme Court in Edwards v. Arthur Andersen LLP, 44 Cal. 4th 937 (CA Supreme Court 2008). There is no contractual "trade secret exception" that allows an employer to enforce a post-employment customer non-solicit covenant, as confirmed in The Retirement Group v. Galante, 176 Cal. App. 4th 1226 (CA Ct. App. 2009). Attempting to enforce or include such void covenants constitutes an actionable civil violation under Cal. Bus. & Prof. Code § 16600.5. Redress against improper customer poaching must be pursued under tort law via the California Uniform Trade Secrets Act (Cal. Civ. Code § 3426 et seq.) and valid confidentiality agreements rather than contractual non-solicitation covenants. Meanwhile, Employee Non-Solicitation clauses (agreements not to recruit former coworkers) face heavy judicial scrutiny following AMN Healthcare, Inc. v. Aya Healthcare Services, Inc., 28 Cal. App. 5th 923 (CA Ct. App. 2018), making them largely unenforceable when applied to post-employment restrictions.

The "Sale of Business" Exception

There is one major exception to the California non-compete ban. Under Cal. Bus. & Prof. Code § 16601, if a person sells the goodwill of a business, or disposes of all their ownership interest in a business entity, they can be subjected to a valid non-compete agreement. This ensures that a founder cannot sell their tech startup for millions, then immediately launch an identical competitor the next day and steal all the goodwill they just sold. These clauses must be carefully restricted in geographic scope and time duration to remain valid in a California Superior Court.

Trade Secret Protection Clauses

Because non-competes are void, your primary legal protection is a meticulously drafted Proprietary Information and Inventions Agreement (PIIA). California courts vigorously protect genuine trade secrets under the Uniform Trade Secrets Act (Cal. Civ. Code § 3426 et seq.). When litigating trade secret misappropriation in court, counsel initiates civil proceedings using Form CM-010, California, Judicial Council, Civil Case Cover Sheet and Form SUM-100, California, Judicial Council, Summons. Your agreements must clearly define what constitutes a trade secret (e.g., proprietary algorithms, non-public customer lists, pricing formulas) and explicitly state that the employee cannot disclose or misappropriate this information during or after their employment. If an employee departs and misappropriates your trade secrets, you can seek injunctive relief and damages under state trade secret statutes without violating Section 16600.

Actionable Advice for Employers: Revising Legacy Contracts

Under Cal. Bus. & Prof. Code § 16600.1 (enacted via Assembly Bill 1076), employers were required to provide individualized written notice by February 14, 2024, to current and former employees hired after January 1, 2022, informing them that any previously signed non-compete covenants are legally void. Under Senate Bill 699 (codified in Cal. Bus. & Prof. Code § 16600.5), entering into or attempting to enforce void restrictive covenants is an unlawful business practice. To protect your business going forward:

• Audit Your Handbooks: Remove any lingering non-compete, customer non-solicitation, or overly broad conflict-of-interest language that restricts post-employment activities.
• Strengthen NDAs: Ensure your confidentiality agreements are strictly limited to protecting proprietary trade secrets without functioning as de facto non-competes.
• Update Offer Letters: Make sure no out-of-state templates containing restrictive covenants are sent to California workers or out-of-state workers who may relocate to California.

How Much Does It Cost to Revise Employment Agreements?

Ignoring California's ban can result in lawsuits from employees and fines from the state. Investing in proactive legal drafting is highly recommended.
