Non-Compete Agreements in Colorado: Are They Enforceable?

Federal law does not regulate non-compete agreements directly. The Federal Trade Commission (FTC) has proposed rules to ban most non-competes, but enforcement remains limited and focused on workers earning less than $75,000. Enforcement of non-competes is primarily a state law matter. Under common law, employers generally have the right to prevent unfair competition, trade secret misappropriation, and the theft of customer lists. However, most states—including Colorado—have adopted statutes that restrict non-competes because they are viewed as unreasonable restraints on an individual's right to work and earn a livelihood. Federal courts sitting in Colorado apply Colorado state law when interpreting non-competes, following the principle that restrictive covenants must be analyzed under the law of the state where the employee works or where the covenant is to be enforced.

The enforceability of non-competes nationwide varies significantly. Some states (California, North Dakota, Oklahoma) ban them almost entirely for employees. Others allow them if reasonable. The absence of uniform federal regulation means employers must comply with the law of each state in which they operate, making Colorado's restrictive approach a meaningful protection for Colorado workers.

Colorado law is among the strictest in the nation regarding non-competes. Under C.R.S. § 8-2-113, restrictive covenants (including non-competes) are presumed to be void and unenforceable as illegal restraints on trade. This presumption shifts the burden entirely to the employer: the employer must affirmatively prove that the non-compete is reasonable and protects a legitimate business interest.

The statute recognizes only three circumstances under which a non-compete may be enforceable: (1) to protect a legitimate business interest (trade secrets, confidential information, substantial relationships with specific prospective or existing customers, or goodwill associated with an ongoing business); (2) in connection with the sale of a business; or (3) in connection with the dissolution of a partnership. A non-compete must be reasonable in temporal scope, geographic scope, and line of business. Colorado courts have consistently held that the employer bears the burden of proving all three elements by clear and convincing evidence, a high standard.

Compared to federal law and many other states, Colorado's approach is significantly more employee-protective. While some states allow non-competes if they are "reasonable," Colorado presumes them void unless the employer meets strict criteria. Additionally, C.R.S. § 8-2-114 prohibits employers from restricting an employee's ability to engage in any profession or trade of any kind, work for any employer, or set forth any special, secret, or other information learned or developed as a result of employment. This means non-competes cannot be used to prevent an employee from using general skills, knowledge, or experience. Non-solicitation and confidentiality provisions are also subject to the same presumption of unreasonableness, though they have a somewhat better chance of enforcement if narrowly limited to actual customers and legitimate trade secrets.

Employers in Colorado cannot circumvent the statute by labeling agreements differently. Courts look to the substance of the restriction, not its title. Employees covered are all persons who work in Colorado, regardless of whether they are full-time, part-time, temporary, or independent contractors (though the applicability to contractors is context-dependent). Employers of all sizes are subject to the statute.

Several narrow exceptions permit non-competes under Colorado law. First, a non-compete protecting a legitimate business interest in the sale of an ongoing business is enforceable if the buyer is restricted from competing in the geographic market where the business operated and for a reasonable period. Second, non-competes incident to the dissolution of a partnership are enforceable if limited to the geographic area in which the partnership conducted business. Third, non-competes protecting legitimate business interests (trade secrets or confidential business information) may be enforceable if they are narrowly tailored.

However, Colorado courts have held that many supposed "legitimate business interests" do not actually justify a non-compete. For example, a general desire to prevent an employee from working for a competitor does not constitute a legitimate business interest. Similarly, general knowledge, skills, experience, and customer relationships developed during employment are not protectable unless they rise to the level of trade secrets or involve substantial, individualized relationships with specific named customers.

An employer cannot enforce a non-compete against an employee who was not properly notified of the covenant at hiring or before employment began. The restrictive covenant must be provided in writing and signed by the employee. Oral non-competes are unenforceable. Additionally, Colorado law prohibits non-competes that restrict an employee's ability to use general knowledge or special information learned during employment unless that information qualifies as a trade secret under Colorado's Uniform Trade Secrets Act (C.R.S. § 7-57-102). Employees terminated without cause or laid off face particular protections; some Colorado courts have questioned whether a non-compete can be enforced against an employee who was not compensated for the post-employment restriction.

Step 1: Document Everything Immediately. If an employer has presented you with a non-compete agreement, photograph or scan the document. Note the date you received it, whether it was provided at hiring or later, whether you signed it, and under what circumstances. If you have already signed the agreement and now wish to challenge it, keep copies of: (1) the signed non-compete, (2) any employment offer letter or handbook provision related to it, (3) emails or communications about the restriction, and (4) evidence of when the covenant was provided to you (pay stubs, emails, onboarding records).

Step 2: Consult with an Employment Attorney Before Taking Action. Do not ignore a non-compete or assume it is unenforceable simply because Colorado law presumes them void. Employers may still attempt to enforce them through litigation or threaten legal action. An employment attorney licensed in Colorado can review the specific language of your non-compete, assess your employer's likely business interests, and advise whether the covenant is void under C.R.S. § 8-2-113. Many attorneys offer free consultations. This step is critical because defending a non-compete lawsuit is expensive, and an incorrect assumption of non-enforceability can be costly.

Step 3: If You Intend to Work for a Competitor or Leave the Industry, Provide Written Notice to Your Employer. Send a letter (email is acceptable) to your employer or their legal counsel stating that you believe the non-compete is unenforceable under Colorado law and explaining your planned employment. Do not make this confrontational; simply state the facts. This creates a contemporaneous record of your position and may discourage frivolous litigation. Retain a copy for your records.

Step 4: Understand the Litigation Process. If your employer sues, they will file a complaint in Colorado District Court (state court) or, if diversity jurisdiction exists, federal court. You will be served with the complaint and have 21 days to respond. The employer bears the burden of proving the non-compete is reasonable by clear and convincing evidence. Discovery will occur, allowing both sides to exchange documents and conduct depositions. The case may settle before trial. Litigation typically takes 6–18 months and costs $5,000–$50,000+ in attorney fees, making settlement or dismissal preferable when possible.

Step 5: Consider Seeking a Declaratory Judgment. If you are certain you want to challenge the non-compete proactively, your attorney may recommend filing a lawsuit for declaratory judgment in Colorado District Court, asking the court to declare the non-compete void. This is riskier because you are initiating litigation, but it may be appropriate if you have a clear case of non-enforceability and your employer has threatened action. Alternatively, wait for your employer to sue if they intend to enforce the agreement.

Step 6: Know When to Involve the Colorado Department of Labor and Employment. The CDLE does not directly enforce non-compete statutes, but your attorney may contact the CDLE's Office of Policy, Research and Regulatory Reform to discuss whether your situation implicates other labor law violations (e.g., unpaid wages, misclassification). If your employer is retaliating against you for refusing to sign a non-compete or for leaving, that may trigger retaliation protections.
