Noncompete Nonsolicit NDA Challenge Letters
California 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 is one of the strongest anti-noncompete laws in the nation. With very narrow exceptions, noncompete agreements are unenforceable in California—even if:
- You signed the agreement voluntarily
- The agreement specifies another state’s law (California courts will still apply § 16600)
- You received consideration (e.g., a signing bonus or promotion)
- The restriction is geographically or temporally limited
California recognizes only three statutory exceptions where noncompetes may be enforceable:
| Exception | Statute | Requirements |
|---|---|---|
| Sale of business goodwill | § 16601 | Seller of a business or owner selling ownership interest; must receive substantial consideration for the business/interest |
| Partnership dissolution | § 16602 | Partners dissolving a partnership or dissociating from an ongoing partnership |
| LLC member dissociation | § 16602.5 | Members dissociating from a limited liability company |
Key point: These exceptions apply only to owners, not regular employees. If you’re a W-2 employee (not an equity-holding partner or business seller), § 16600 voids your noncompete.
California courts are more tolerant of narrow nonsolicitation agreements, but they must be carefully limited:
| Type | Enforceability in CA |
|---|---|
| Customer nonsolicitation | Generally unenforceable under § 16600 (restrains employee’s ability to work) |
| Employee nonsolicit (anti-poaching) | Narrowly enforceable if limited to active solicitation (not merely hiring former colleagues who apply voluntarily) |
| Trade secret / confidential info restrictions | Enforceable under California Uniform Trade Secrets Act (CUTSA) and common law, but cannot be disguised noncompetes |
NDAs are generally enforceable in California, but only if they:
- Protect actual trade secrets (as defined by CUTSA: information with independent economic value that’s subject to reasonable secrecy efforts)
- Do not function as a disguised noncompete (e.g., defining “confidential information” so broadly that the employee cannot work in the industry)
- Do not violate SB 331 (prohibits NDAs that prevent disclosure of workplace harassment, discrimination, or sexual assault)
In January 2023, the FTC proposed a nationwide rule banning noncompete clauses for all workers (employees and independent contractors). Key provisions of the proposed rule:
- Employers could not enter into, enforce, or even represent that workers are subject to noncompetes
- Existing noncompetes would be rescinded
- Trade secret protections and customer nonsolicits might still be allowed if narrowly tailored
- Employers would be required to notify workers that their noncompetes are void
Status: As of 2025, the rule is still subject to legal challenges and has not yet taken effect. However, it signals strong federal policy against noncompetes.
Review your employment agreement, offer letter, or separation agreement and identify all restrictive covenants:
| Type | What It Restricts | Example Language |
|---|---|---|
| Noncompete | Working for a competitor or starting a competing business | “Employee shall not work for any competitor within 50 miles for 2 years after termination” |
| Customer nonsolicit | Soliciting or servicing the employer’s customers | “Employee shall not solicit or service any customer of Company for 1 year” |
| Employee nonsolicit | Recruiting or hiring former colleagues | “Employee shall not solicit any employee of Company to leave employment” |
| Nondisclosure (NDA) | Disclosing confidential information or trade secrets | “Employee shall not disclose Confidential Information, including customer lists, pricing, and processes” |
| Invention assignment | Claiming ownership of inventions/IP created during employment | “All inventions made during employment belong to Company” |
Use this flowchart to determine if your restriction is likely enforceable:
- Is it a noncompete?
- ✅ If you’re in California and not an owner/partner selling a business: VOID under § 16600
- ⚠️ If the agreement specifies another state’s law, California courts will still apply § 16600 for CA residents/workers
- Is it a customer nonsolicit?
- ❌ Likely unenforceable under Edwards if it materially restrains your ability to work
- ✅ Possibly enforceable if extremely narrow and tied to trade secret protection
- Is it an employee nonsolicit?
- ✅ Narrowly enforceable if limited to active poaching (not merely hiring former colleagues who apply on their own)
- Is it an NDA?
- ✅ Enforceable if it protects actual trade secrets and doesn’t function as a noncompete
- ❌ Void if it prohibits disclosure of harassment, discrimination, or assault (SB 331)
- ❌ Overbroad if it defines “confidential” to include general industry knowledge or skills
Even if a restriction could be enforceable in theory, it may be void if overbroad:
| Red Flag | Why It’s Problematic |
|---|---|
| Definition of “competitor” is vague or overly broad | Covers entire industry or unrelated business lines |
| Geographic scope too wide | “Nationwide” or “worldwide” restrictions for local business |
| Duration too long | Restrictions lasting more than 1–2 years (even in states that allow noncompetes) |
| “Confidential information” defined to include general knowledge | NDA covers skills, experience, or industry knowledge not protectable as trade secrets |
| No consideration provided | Agreement imposed after employment started with no raise, promotion, or other benefit |
| Prohibits disclosure of illegal conduct | NDA prevents reporting harassment, discrimination, wage violations, or other illegal acts |
Assess your negotiating position:
- Strong leverage (employer unlikely to enforce):
- You’re in California and the restriction is a noncompete or customer nonsolicit
- The agreement is overbroad or vague
- You didn’t receive meaningful consideration
- The employer has a history of not enforcing these clauses
- Moderate leverage (uncertain enforceability):
- Employee nonsolicit (narrow scope might be enforceable)
- NDA that includes some trade secrets but also general knowledge
- You’re moving to a role that arguably doesn’t compete
- Weak leverage (likely enforceable):
- NDA covering clear, specific trade secrets (formulas, customer data, proprietary processes)
- You actually plan to use or disclose trade secrets
- You’re an owner/partner subject to a § 16601/16602 exception
Consider sending a pre-emptive challenge letter if:
- You’re planning to leave for a new job and want to clear the air before starting
- The employer has threatened to enforce the restriction
- You want to force the employer to commit to non-enforcement in writing
- You’re seeking a declaratory judgment that the restriction is void and want to show good faith
- Identify the agreement: Reference the specific contract and restrictive covenant provision
- State your position: Clearly state you believe the restriction is unenforceable and why
- Legal basis: Cite California Bus. & Prof. Code § 16600, Edwards, SB 699, and any other applicable law
- Factual support: Explain why you don’t fit the narrow exceptions (you’re not an owner, not selling a business, etc.)
- Overbreadth arguments: Point out vague terms, excessive scope, lack of consideration
- Request for confirmation: Ask employer to confirm in writing they will not enforce the restriction
- Consequence of enforcement: Warn that you will seek declaratory relief, attorneys’ fees, and potentially damages under SB 699

[Company Address]
[City, State, ZIP]Re: Noncompete Agreement – Notice of Unenforceability Under California Law
Dear [Employer]:
I am writing regarding the noncompetition provision in the [Employment Agreement / Offer Letter / Separation Agreement] I signed on [date] (the “Agreement”). Specifically, Section [X] of the Agreement purports to prohibit me from working for a competitor or soliciting customers of [Company] for [X years/months] following the termination of my employment.
I am writing to inform you that this provision is void and unenforceable under California law, and I will not be bound by it.
Legal Basis:
California Business & Professions Code § 16600 provides: “Except as provided in this chapter, 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 California Supreme Court has made clear that § 16600 applies broadly to any restraint on an employee’s ability to compete, regardless of geographic or temporal limitations. Edwards v. Arthur Andersen LLP, 44 Cal. 4th 937 (2008).
The noncompete provision in our Agreement does not fall within any of the narrow statutory exceptions (§§ 16601, 16602, 16602.5), which apply only to owners selling a business or partners dissolving a partnership. I was a [W-2 employee / salaried employee] with no ownership interest in [Company], and I did not sell any business interest or goodwill. Therefore, § 16600 voids the noncompete in its entirety.
Moreover, California Senate Bill 699, effective January 1, 2024, makes it unlawful for employers to enter into or attempt to enforce noncompete agreements with employees. Employers who violate SB 699 face civil penalties and may be required to notify affected employees that the agreements are void.
Request for Confirmation:
I respectfully request that you confirm in writing, within 10 business days, that [Company] will not enforce or attempt to enforce the noncompete provision in the Agreement, and that I am free to accept employment with any employer of my choosing without restriction.
If I do not receive such confirmation, or if [Company] threatens to enforce the noncompete, I will have no choice but to seek declaratory relief in court. Under California law, I would be entitled to recover my attorneys’ fees and costs if I prevail. Additionally, any attempt to enforce this void provision may subject [Company] to penalties under SB 699.
I remain willing to honor any valid obligations under the Agreement, including the nondisclosure of legitimate trade secrets. However, the noncompete provision is not among them.
Please direct all communications to me at [email] or [phone].
Sincerely,
[Your Signature]

Re: Overbroad Nondisclosure Agreement – Request for Clarification
Dear [Employer]:
I am writing regarding the Nondisclosure Agreement I signed on [date]. While I acknowledge my obligation to protect [Company]’s legitimate trade secrets, I believe certain provisions of the NDA are overbroad and unenforceable under California law.
Specifically, the NDA defines “Confidential Information” to include “[broad definition, e.g., ‘any information related to the business’].” This definition sweeps in general industry knowledge, skills, and experience that I have acquired over the course of my career and that are not protectable trade secrets under the California Uniform Trade Secrets Act (CUTSA).
Under California law, an NDA cannot function as a disguised noncompete by prohibiting an employee from using general knowledge or skills in their profession. Edwards v. Arthur Andersen. To the extent the NDA purports to restrict me from working in [industry] or using skills I have developed, it is void under § 16600.
I request that [Company] clarify in writing which specific information it considers “trade secrets” subject to the NDA, so that I can ensure compliance while exercising my right to pursue my livelihood. I am happy to protect bona fide trade secrets, such as [specific examples: proprietary formulas, customer data not publicly available, etc.], but I will not be restricted from using general industry knowledge or skills.
Please respond within 10 business days. If [Company] takes the position that the NDA restricts me from working in [industry] or using general knowledge, I will seek declaratory relief.
Sincerely,
[Your Name]
- When to send: Ideally 2–4 weeks before starting a new job, giving the employer time to respond but not so much time they can prepare litigation
- How to send: Certified mail + email to General Counsel or HR Director
- Copies: Send to your new employer’s legal team (if applicable) so they’re aware of the issue
| Response | What It Means | Your Next Step |
|---|---|---|
| Written confirmation of non-enforcement | Employer agrees restriction is void; gives you clearance | Keep the letter and proceed with new job |
| No response | Employer may be hoping you’ll comply out of fear, or may be deciding whether to sue | Proceed with new job; most employers don’t sue if they don’t respond to challenge letter |
| Letter asserting enforceability | Employer claims restriction is valid and threatens to enforce | Consult attorney; consider filing declaratory judgment action before they file for TRO |
| Cease and desist / demand letter | Employer threatens immediate legal action if you violate restriction | Do not ignore; consult attorney immediately; may need to file declaratory action or defend TRO motion |
| Lawsuit or TRO filing | Employer files for emergency injunction to prevent you from starting new job | Hire attorney immediately to oppose TRO and counterclaim for declaratory relief and attorneys’ fees |
If the employer insists the restriction is valid, you can negotiate a release in exchange for:
- Payment: Employer pays you (e.g., 3–6 months’ salary) to release you from the restriction
- Narrowing the restriction: Limit geographic scope, duration, or definition of “competitor”
- Carve-out for specific employer: Employer agrees you can work for [New Company] without violating the agreement
- Standstill: Both parties agree not to sue while you work at the new job; if no problems arise in 6–12 months, employer releases you
Your new employer has a stake in this too (they’re hiring you). Many new employers will:
- Indemnify you (agree to cover legal fees if former employer sues)
- Provide legal counsel to defend against TROs or lawsuits
- Negotiate directly with the former employer to resolve the dispute
- Structure your role to avoid arguable competition (at least initially)
Inform your new employer’s legal team about the restrictive covenant before you accept the offer, so they can assess the risk and provide support.
If the employer refuses to back down, you can file a declaratory judgment action asking the court to declare the restrictive covenant void.
| Aspect | Details |
|---|---|
| Venue | California Superior Court (or federal court if diversity jurisdiction) |
| Claims | Declaratory relief (restriction is void under § 16600); request for attorneys’ fees |
| Advantages | You control timing and forum; shifts burden to employer to prove enforceability; fee-shifting available |
| Timeline | 6–12 months to summary judgment; most cases settle or are dismissed on demurrer/motion to dismiss |
| Outcome | Court declares restriction void; employer may be ordered to pay your attorneys’ fees |
If the employer files for emergency injunctive relief, you must oppose vigorously:
- Show § 16600 voids the restriction: Cite Edwards and argue employer cannot show likelihood of success on the merits
- No irreparable harm: Employer’s harm (if any) is economic and can be remedied by damages; not a basis for injunction
- Overbreadth: Highlight vague terms, excessive scope, lack of trade secret protection
- Public policy: Enforcing the restriction would harm public policy favoring employee mobility
- Unclean hands: If employer violated wage laws, harassed you, or acted in bad faith, argue they don’t deserve equitable relief
If the employer sues to enforce the restriction, raise these defenses:
| Defense | Argument |
|---|---|
| § 16600 | Restriction is void as a restraint on trade; no exceptions apply |
| Overbreadth | Restriction is vague, overly broad, or not reasonably necessary to protect legitimate business interests |
| Lack of consideration | Restriction was imposed after employment started with no new benefit (pay raise, promotion, etc.) |
| SB 699 violation | Employer violated SB 699 by entering into noncompete after Jan 1, 2024 |
| No trade secrets | Employer cannot identify any actual trade secrets you possess or threaten to disclose |
| Unclean hands | Employer violated wage laws, engaged in misconduct, or otherwise acted inequitably |
| Laches / waiver | Employer delayed enforcing restriction, or previously allowed other employees to violate it |
If the employer sues you, consider counterclaiming for:
- Declaratory relief: Ask the court to declare the restriction void
- Attorneys’ fees: Under California Code of Civil Procedure § 1021.5 (private attorney general statute) or Civil Code § 1717 (contract fee-shifting)
- SB 699 penalties: If employer entered into or attempted to enforce a noncompete after Jan 1, 2024
- Unfair competition (Bus. & Prof. Code § 17200): Employer’s attempt to enforce void restriction is an unfair business practice
- Wrongful termination / retaliation: If employer fired you for refusing to sign restriction or for challenging it
Most noncompete disputes settle. Typical settlement terms:
- Release: Employer releases you from the restriction entirely
- Narrow carve-out: Employer agrees you can work for [specific company] or in [specific role] without violating the agreement
- Standstill: Both parties agree not to sue for X months; restriction expires or is waived if no issues arise
- Payment: Employer pays you to settle (often to cover your legal fees and as consideration for release)
- NDA carve-down: Employer narrows the definition of “confidential information” to exclude general knowledge
