California Business & Real Estate: NDAs, Not Non-Competes

Why Non-Competes Don't Fly in California

California policy strongly favors open competition and employee mobility. Except for narrow statutory exceptions tied to the sale or dissolution of a business, contracts that restrain anyone from engaging in a lawful profession, trade, or business are generally void under Bus. & Prof. Code § 16600. The California Supreme Court confirmed this broad rule in Edwards v. Arthur Andersen LLP (2008). Limited exceptions exist for sellers of a business, equity holders, and partnership/LLC dissolutions (§§ 16601–16602.5).

Recent legislation further reinforces the ban and expands remedies: § 16600.5 (effective 2024) makes it unlawful to enter into or attempt to enforce a non-compete regardless of where it was signed and provides a civil cause of action; § 16600.1 codifies that non-competes are void and, for certain employers, requires notice to current and certain former employees that such clauses are unenforceable.

NDAs Are the Lawful Alternative

Non-disclosure agreements are generally enforceable in California when they focus on preventing misuse or disclosure of protected information rather than restricting lawful competition. Properly drafted NDAs protect trade secrets and confidential, competitively sensitive information without functioning as de facto non-competes. See CUTSA (Cal. Civ. Code §§ 3426–3426.11) and the federal DTSA, 18 U.S.C. § 1836.

What an Effective California NDA Should Cover

• Clear definition of “Confidential Information”: Identify categories (e.g., financials, rent rolls, pro formas, customer lists, pricing, deal terms, algorithms, source code, supplier terms, site plans, environmental reports). Tie protected information to economic value and reasonable secrecy measures (consistent with CUTSA).
• Purpose limitation: Limit use to a defined purpose (e.g., evaluating a potential investment, purchase, JV, or employment opportunity).
• Standard exclusions: Public information; independently developed information; information rightfully obtained from a third party; or already known without restriction.
• Permitted disclosures: Allow sharing with affiliates, advisors, lenders, or financing sources who need to know and are bound by equal or stricter confidentiality obligations; address disclosures compelled by law with prompt notice and protective-order cooperation where lawful.
• Duration: Use a reasonable period tied to the industry and sensitivity; trade secrets may be protected for as long as they remain trade secrets.
• Return or destruction: Require return or secure destruction (including derivatives) at the end of the evaluation or on request, allowing routine backups to be retained subject to ongoing confidentiality.
• Remedies: Reserve injunctive and other equitable relief, in addition to damages, consistent with California law.
• No non-compete by stealth: Make clear the agreement does not restrict lawful competition, hiring, or engagement in a profession. Avoid “no-hire” or broad non-solicitation terms that functionally restrain employment; California courts have invalidated such restraints in many contexts (e.g., AMN Healthcare v. Aya Healthcare (2018); Dowell v. Biosense Webster (2009)).

Special Focus: Business Sales and M&A

California permits limited restraints connected to the sale of a business’s goodwill or all ownership interests (Bus. & Prof. Code §§ 16601–16602.5). In practice, buyers should rely primarily on NDAs during early diligence. Post-closing, tailor any restrictive covenants to fit statutory exceptions. Pre-closing, avoid provisions that bar a seller or management from competing; instead, use NDAs, carefully considered standstill provisions where appropriate, and narrowly crafted terms vetted for California compliance.

Real Estate Deals: Practical NDA Uses

Commercial real estate diligence often requires sharing rent rolls, tenant financials, underwriting models, site information, and lender terms. NDAs help mitigate leakage risk in marketing processes and coordinate disclosures among brokers, sellers, prospective buyers, lenders, JV partners, and property managers. Ensure all downstream recipients are bound by equal or stricter confidentiality obligations.

Employment and Startups: Protecting Know-How Without Overreach

Employers can protect source code, customer data, pricing, roadmaps, and other trade secrets through NDAs and proprietary information agreements, paired with training and access controls to demonstrate reasonable secrecy measures. Avoid converting confidentiality into a restraint on employment: don’t define “confidential” so broadly that it covers general skills and knowledge; don’t prohibit lawful post-employment work; and be cautious with any non-solicitation or no-hire terms, which courts have often found void under § 16600 (see AMN Healthcare; Dowell). 2024 updates (§ 16600.1; § 16600.5) also underscore enforcement risk for non-compete-type restraints.

Trade Secret Backbone: CUTSA and DTSA

California’s Uniform Trade Secrets Act (Cal. Civ. Code §§ 3426–3426.11) and the federal Defend Trade Secrets Act (18 U.S.C. § 1836) provide robust remedies for misappropriation. NDAs complement these statutes by defining what is protected, documenting secrecy measures, and establishing contractual remedies. For employee or contractor NDAs, include the DTSA whistleblower immunity notice to preserve eligibility for certain exemplary damages and attorneys’ fees (18 U.S.C. § 1833(b)).

Common Pitfalls to Avoid

• Overbroad definitions that sweep in public or generalized knowledge.
• “No-hire” or de facto non-compete provisions that functionally restrain lawful employment.
• Unlimited sharing with affiliates or advisors without flow-down confidentiality obligations.
• Ambiguous durations suggesting perpetual secrecy for non-trade-secret information without justification.
• Failing to mark or track disclosures, undermining claims of reasonable secrecy measures.

FAQ

Are non-solicitation clauses enforceable in California?

Many employee non-solicitation and no-hire clauses are viewed as unlawful restraints under § 16600. Narrow, transaction-specific nonsolicits in a sale of business may be permissible within statutory limits.

Can I protect information shared with potential buyers or investors?

Yes. Use a purpose-limited NDA with clear definitions, exclusions, flow-down obligations to advisors, and return/destruction terms.

How long should confidentiality last?

Set a reasonable period for non-trade-secret information based on the deal and industry. Trade secrets can be protected for as long as they remain trade secrets.

Do I need to mark every document?

Marking helps show reasonable secrecy measures. Pair labels with controlled access, logs, and training.
