Montana non-compete agreement: how the statute restricting restraints on trade works, the interaction with Montana's unique wrongful-discharge law, the reasonableness exception, and what employees should know
Montana disfavors restraints on trade
Montana's approach to non-compete agreements begins with a statutory provision that disfavors restraints on trade. Montana Code Annotated §28-2-703 provides that any contract by which anyone is restrained from exercising a lawful profession, trade, or business of any kind is void, with limited exceptions for the sale of business goodwill (§28-2-704) and the dissolution of a partnership (§28-2-705).
This statutory structure resembles the ban states — California, North Dakota, and Oklahoma — which use similar language declaring restraints on trade void. However, Montana courts have interpreted the statute differently from the strictest ban states, recognizing a judicial exception for reasonable employment non-competes that protect a legitimate business interest. The result is a framework that starts from statutory disfavor but permits enforcement of reasonable restrictions through judicial interpretation.
The Montana Supreme Court has held that, despite the broad statutory language voiding restraints on trade, a non-compete may be enforceable if it is reasonable — limited in scope, geography, and duration, supported by good consideration, and necessary to protect the employer's legitimate interests. This judicial reasonableness exception distinguishes Montana from the pure ban states, where the statutory prohibition is applied more strictly.
The reasonableness exception
Montana courts evaluate employment non-competes under a reasonableness analysis developed through case law interpreting the statute. A non-compete may be enforced if it is partial or restricted in its operation as to time or place, is based on good consideration, and is reasonable — affording fair protection to the employer's interests without being so broad as to interfere with the public interest or impose undue hardship on the employee.
The Montana Supreme Court articulated this framework in decisions including Dobbins, DeGuire & Tucker, P.C. v. Rutherford, MacDonald & Olson (1985) and subsequent cases. The analysis requires the employer to demonstrate that the restriction is reasonable in its scope and necessary to protect a genuine business interest.
Montana recognizes the standard protectable interests: trade secrets, confidential business information, customer relationships and goodwill, and specialized training. Montana has adopted the Uniform Trade Secrets Act (Mont. Code Ann. §30-14-401 et seq.), and the statutory definition informs the analysis. The employer must identify a specific protectable interest; the statutory disfavor of restraints on trade means Montana courts scrutinize the employer's claimed interest carefully.
The interaction with Montana's wrongful-discharge law
Montana is unique among all U.S. states in one fundamental respect: it is the only state that is not an at-will employment state. Under the Montana Wrongful Discharge from Employment Act (Mont. Code Ann. §39-2-901 et seq.), an employer cannot terminate a non-probationary employee without good cause. This makes Montana the only state where employees have statutory protection against termination without cause as a baseline matter.
This unique employment framework interacts with non-compete enforcement in significant ways. In every other state, the at-will nature of employment creates tension with non-compete enforcement — an employer can fire an employee at any time and then seek to restrict their competitive activity. In Montana, the good-cause requirement changes the dynamic. An employer who terminates an employee must have good cause, and the circumstances of a termination — which the wrongful-discharge law already scrutinizes — become relevant to the equity of enforcing a non-compete against the terminated employee.
If an employee is terminated without good cause in violation of the wrongful-discharge law, the employee has a claim against the employer, and the equity of enforcing a non-compete against an employee who was wrongfully discharged is questionable. Conversely, an employee terminated for good cause (genuine misconduct or documented performance failure) is in a weaker equitable position. The good-cause framework adds a dimension to the non-compete analysis that doesn't exist in at-will states.
For employees, the wrongful-discharge law provides a backdrop of protection that affects the non-compete calculus. An employee facing both a wrongful termination and an attempt to enforce a non-compete has overlapping claims and defenses that arise from Montana's distinctive employment framework.
Duration, geography, and scope
Montana courts evaluate reasonableness across the standard dimensions, applying the scrutiny that flows from the statutory disfavor of restraints on trade.
For duration, one year is generally reasonable. Two years may be upheld in circumstances involving significant protectable interests. Restrictions beyond two years face substantial scrutiny given the statutory disfavor of restraints.
For geographic scope, the restriction must correspond to the employer's competitive territory and the employee's area of responsibility. Montana is geographically large but sparsely populated, with the economy concentrated in a handful of population centers — Billings, Missoula, Great Falls, Bozeman, and Helena — separated by substantial distances. Courts evaluate geographic restrictions with reference to the specific market the employee served, and the state's geography means that a restriction covering a single city may leave substantial alternative opportunities elsewhere in the state, while a statewide restriction may be overbroad for an employee who served only one region.
For scope of activity, the restriction must be limited to genuinely competitive work that threatens the protectable interest.
The sale-of-business and partnership exceptions
Like the ban states, Montana's statute expressly permits non-competes in the sale-of-business context (§28-2-704) and the partnership-dissolution context (§28-2-705). A person who sells the goodwill of a business may agree not to compete with the buyer within a specified area, and partners may agree not to compete upon dissolution. These exceptions reflect the universal principle that protecting transferred goodwill or a business division among owners justifies restrictions that wouldn't be permitted in the ordinary employment context.
Non-solicitation, non-disclosure, and trade secrets
Because Montana's statute disfavors restraints on trade and the reasonableness exception is applied with scrutiny, employers often turn to narrower restrictive covenants. Customer non-solicitation agreements restrict the former employee from soliciting the employer's clients without barring competition generally, and Montana courts evaluate them with the same skepticism toward restraints on trade, but the narrower scope can make them easier to sustain because they impose less hardship.
Non-disclosure agreements protecting genuine trade secrets and confidential information are governed by the Montana Uniform Trade Secrets Act and general contract principles. An NDA restricts what the employee can disclose or use, not where the employee can work, and provides protection independent of any non-compete. Because the NDA doesn't restrain the employee's ability to practice their trade or profession, it isn't subject to the same statutory disfavor that applies to non-competes. For an employer whose primary concern is protecting confidential information, an NDA combined with a non-solicitation provision can achieve substantial protection even where the statutory disfavor of restraints makes a non-compete difficult to enforce.
For employees, this means that even when a non-compete is void or scrutinized under Montana's framework, separate non-solicitation and confidentiality obligations may still apply, and each provision should be evaluated independently.
Choice-of-law considerations
For employees who work in Montana for out-of-state employers, the choice-of-law analysis affects whether Montana's distinctive framework applies. Montana courts generally apply Montana law to employment relationships centered in the state, and Montana's strong statutory policy disfavoring restraints on trade — combined with its unique wrongful-discharge protections — provides a basis for applying Montana law even when an agreement designates another state's law.
This matters because the difference between Montana's framework and the frameworks in neighboring states is substantial. An employer based in a state that enforces non-competes under a reformation-friendly framework may include a choice-of-law provision designating that state's law, hoping to access more favorable rules. For employees who primarily work in Montana, Montana's public policy disfavoring restraints on trade, and its unique status as the only non-at-will state, may override that designation. The combination of the anti-restraint statute and the wrongful-discharge law gives Montana employees a distinctive set of protections that the state's courts may apply notwithstanding a contractual choice of another state's law.
The energy, natural resources, and healthcare context
Montana's economy includes significant energy and natural resources sectors — coal, oil and gas in the eastern part of the state, along with mining, timber, and agriculture. Employees in these sectors frequently have access to proprietary technical information, geological data, and specialized expertise that constitutes genuine confidential information. Despite the value of these protectable interests, Montana's statutory disfavor of restraints on trade means employers must demonstrate that any non-compete is reasonable and necessary, and the courts scrutinize the claimed interest carefully.
Montana's healthcare sector generates a distinctive category of non-compete disputes, and the foundational Dobbins and Reddy-line cases reflect the courts' attention to the public interest in healthcare access. Montana's vast geography and sparse population make healthcare access a persistent concern — many communities are served by a small number of providers, and the departure of a physician can leave an area underserved. A non-compete that would prevent a physician from practicing in a region where few alternatives exist faces substantial scrutiny under both the reasonableness analysis and the public-interest consideration.
The interaction with Montana's wrongful-discharge law is particularly significant in these sectors. Because Montana is the only non-at-will state, an employer's decision to terminate an employee is itself subject to the good-cause requirement, and the circumstances of a termination affect both the wrongful-discharge analysis and the equity of enforcing a non-compete. An energy or healthcare employee terminated without good cause has overlapping claims and defenses arising from Montana's distinctive employment framework.
The practical enforcement landscape
Montana non-compete litigation is concentrated in the district courts of Yellowstone County (Billings), Missoula County, and Gallatin County (Bozeman), along with the federal District of Montana.
Enforcement is most common in healthcare, financial services, technology (Bozeman and Missoula have growing technology sectors), professional services, and the natural resources and agriculture sectors. Montana's economy and geography shape the non-compete landscape — the sparse population and concentrated employment centers mean that geographic restrictions are evaluated with attention to the realistic alternative opportunities available to a departing employee.
The statutory disfavor of restraints on trade, combined with the reasonableness scrutiny and the unique wrongful-discharge framework, makes Montana a moderately employee-protective state. Litigation costs are moderate: $20,000 to $90,000 through preliminary injunction is a reasonable range.
What Montana employees should know
Montana's statute disfavors restraints on trade, and non-competes are void unless they fall within the judicial reasonableness exception. The employer must demonstrate that the restriction is reasonable in scope, geography, and duration, supported by good consideration, and necessary to protect a genuine business interest.
Montana's unique status as the only non-at-will state matters. If you were terminated without good cause, you have a claim under the Wrongful Discharge from Employment Act, and the equity of enforcing a non-compete against a wrongfully discharged employee is questionable. The good-cause framework provides a backdrop of protection that affects the non-compete analysis.
The employer must identify a genuine protectable interest — trade secrets, customer relationships, or specialized training. The statutory disfavor of restraints means courts scrutinize the claimed interest carefully.
If you're negotiating a severance agreement, the statutory disfavor of restraints and the wrongful-discharge framework give you arguments for release or narrowing. If you believe enforcement constitutes retaliation, that context affects the analysis.
The national overview positions Montana as a moderately protective state with a distinctive framework — the statutory disfavor of restraints on trade places it closer to the ban states than to the reasonableness states in its starting posture, while the judicial reasonableness exception permits enforcement of genuinely reasonable restrictions. Montana's unique non-at-will employment law adds a dimension that exists in no other state.
