Non-Compete Agreements: What's Enforceable
Quick Answer
Non-compete agreements are enforceable in most states if they are reasonable in scope, duration, and geographic area, supported by adequate consideration, and necessary to protect a legitimate business interest such as trade secrets, customer relationships, or specialized training.
Step-by-Step Guide
- 1Understand what makes a non-compete enforceable
Courts generally evaluate non-compete agreements on four criteria: (1) Is the restriction necessary to protect a legitimate business interest (trade secrets, confidential customer information, specialized training provided by the employer)? (2) Is the duration reasonable (typically 6 months to 2 years)? (3) Is the geographic scope reasonable (limited to the area where the company actually does business)? (4) Does the restriction impose an undue hardship on the employee or harm the public interest? All four factors must be met for the agreement to be enforced.
- 2Identify the legitimate business interest being protected
A non-compete must protect a specific, legitimate business interest. Common recognized interests include: protection of trade secrets and proprietary information, protection of customer relationships and goodwill, protection of investment in specialized training, and protection of confidential business strategies. A general desire to prevent competition is not a legitimate interest. Courts will not enforce non-competes that merely prevent an employee from using general skills and knowledge gained during employment.
- 3Ensure adequate consideration supports the agreement
A non-compete must be supported by consideration (something of value given in exchange). For new employees, the job itself is usually sufficient consideration. For existing employees, additional consideration is required in most states, such as a promotion, raise, bonus, access to confidential information, or additional training. Some states (like Texas) require that the non-compete be ancillary to an otherwise enforceable agreement. Lack of consideration is one of the most common grounds for invalidating a non-compete.
- 4Draft reasonable restrictions on scope and duration
The more narrowly tailored the restrictions, the more likely they are to be enforced. Duration: 6 to 12 months is most commonly enforced; 1 to 2 years is the outer limit in most jurisdictions; anything beyond 2 years is rarely enforced. Geographic scope: should be limited to the area where the company actually competes. Activity scope: should be limited to the specific type of work the employee performed, not all employment in the industry.
- 5Know which states restrict or ban non-competes
The legal landscape for non-competes has shifted dramatically in recent years. California bans non-competes almost entirely (Cal. Bus. & Prof. Code 16600). North Dakota, Oklahoma, and Minnesota have also enacted broad bans. Colorado restricts non-competes to employees earning above a salary threshold ($123,750 as of 2024). Illinois bans non-competes for employees earning under $75,000. Several other states have enacted salary thresholds or other restrictions. The FTC proposed a nationwide ban in 2024 but it was blocked by federal courts.
- 6Consider alternatives to non-compete agreements
If non-competes are unenforceable in your state or you want additional protections, consider alternatives: non-solicitation agreements (preventing the employee from soliciting your clients or employees) are generally more enforceable and less restrictive. Non-disclosure agreements protect trade secrets without restricting future employment. Garden leave clauses pay the employee during the restricted period, increasing enforceability. Forfeiture-for-competition clauses condition deferred compensation on non-competition.
State-by-State Differences
| State | Key Difference |
|---|---|
| California | California prohibits non-compete agreements for employees and independent contractors almost entirely (Cal. Bus. & Prof. Code 16600). Effective January 1, 2024, AB 1076 and SB 699 further strengthened this ban by voiding non-competes signed in other states if the employee lives or works in California. Employers who require California employees to sign non-competes can face penalties. The only exceptions are in connection with the sale of a business or dissolution of a partnership. |
| Texas | Texas enforces non-competes that are ancillary to an otherwise enforceable agreement and contain limitations as to time, geographical area, and scope of activity that are reasonable (Tex. Bus. & Com. Code 15.50). Texas courts have the power to reform (blue-pencil) overly broad non-competes to make them reasonable rather than invalidating them entirely. Non-competes must be supported by consideration beyond at-will employment. |
| Florida | Florida is one of the most non-compete-friendly states. Under Fla. Stat. 542.335, non-competes are presumptively reasonable if they last 6 months or less, and presumptively unreasonable if they exceed 2 years (for former employees). Florida courts do not consider hardship to the employee when determining enforceability, only whether the agreement protects a legitimate business interest. Florida allows "blue-penciling" to narrow overly broad agreements. |
| New York | New York currently enforces non-competes under common law, requiring that they be reasonable in time and scope, necessary to protect a legitimate business interest, not harmful to the public, and not unduly burdensome to the employee. A bill to ban most non-competes has been proposed multiple times and remains under consideration as of early 2026. New York courts apply strict scrutiny and will not enforce non-competes against low-wage workers. |
| Illinois | The Illinois Freedom to Work Act (820 ILCS 90) prohibits non-compete agreements for employees earning less than $75,000 per year (increasing by $5,000 every 5 years through 2037). For employees above the threshold, non-competes must protect a legitimate business interest, be supported by adequate consideration (2 years of continued employment for existing employees), and be reasonable in scope. Illinois also requires employers to advise employees to consult an attorney before signing. |
Common Mistakes to Avoid
Using a one-size-fits-all non-compete for all employees regardless of their role or access to sensitive information
Consequence: Courts are unlikely to enforce a non-compete against a low-level employee who has no access to trade secrets or key customer relationships. Overbroad application weakens the enforceability of the agreement for everyone and may be viewed by courts as evidence that the employer is not protecting a legitimate business interest.
Imposing an unreasonably long duration or overly broad geographic restriction
Consequence: Courts in many states will void the entire non-compete if it is unreasonable rather than modifying it (states without blue-pencil provisions). Even in states that allow judicial modification, overreaching signals bad faith and makes courts less sympathetic to enforcement.
Failing to provide adequate consideration for existing employees
Consequence: In most states, requiring an existing at-will employee to sign a non-compete without additional consideration (bonus, promotion, continued employment for a guaranteed period) renders the agreement unenforceable. The employee can sign the agreement and later successfully challenge it in court on consideration grounds.
Not enforcing non-competes consistently
Consequence: If you allow some former employees to violate their non-competes without action but then try to enforce against others, the court may find that you have waived your right to enforce or that the interest you claim to protect is not genuinely legitimate. Selective enforcement can also support a discrimination claim.
