Non-compete agreements are enforceable in Michigan, but only when they pass the reasonableness test in MCL 445.774a. An employer can restrict where and how a former employee works, but the restriction has to protect a real business interest and stay within reasonable limits on time, geography, and type of activity. The catch most employees don’t see coming: if the agreement is too broad, a Michigan court can rewrite it into something enforceable instead of throwing it out.1Michigan Legislature. MCL – Section 445.774a
The Four-Part Reasonableness Test
Michigan doesn’t apply a rigid formula. Courts weigh the employer’s need for protection against the burden on the employee, and every enforceable non-compete has to clear four hurdles.
A Legitimate Business Interest
The employer has to point to something worth protecting. The recognized interests are trade secrets, confidential business information, customer relationships built on the employer’s time and resources, and goodwill. A non-compete that exists just to prevent competition, with no specific interest attached, won’t survive.1Michigan Legislature. MCL – Section 445.774a
A Reasonable Duration
Michigan courts haven’t set a bright-line maximum. In practice, one to two years is the most common range and the most likely to be upheld. A 20-year restriction has been found unreasonable, though the court trimmed it to three years rather than voiding it. The longer the restriction, the stronger the justification has to be.
A Reasonable Geographic Scope
The territory covered should match where the employer actually does business. A statewide ban may be fine for a company with operations across Michigan; the same ban would be hard to justify for a company serving one county. In one federal case applying Michigan law, a 50-mile radius from an Ann Arbor office was struck down because the employee actually made sales from other cities. In another, a worldwide restriction held up because the employer genuinely operated internationally.
A Reasonable Scope of Activity
The restriction on what work you can do has to be narrowly tailored. Blocking you from your entire industry when the employer only competes in a niche is likely too broad. The question is whether the restriction stops you from using the specific knowledge or relationships you gained on the job, not whether it inconveniences a competitor.
Why an Overbroad Agreement Isn’t a Free Pass
This is where Michigan law surprises people. Under MCL 445.774a, if a court finds a non-compete unreasonable, it “may limit the agreement to render it reasonable in light of the circumstances in which it was made and specifically enforce the agreement as limited.”1Michigan Legislature. MCL – Section 445.774a Lawyers call this blue-penciling.
The result: an employee who challenges an overbroad agreement can win the argument that the original terms were unreasonable and still end up subject to a narrower, enforceable version. The court fixes the employer’s drafting mistakes rather than punishing them, and that alone deters a lot of workers from testing their agreements at all.
What Counts as Valid Consideration
A non-compete needs consideration, like any contract. When you sign as part of accepting a job, the job itself is the consideration and that ends the analysis.
Mid-employment signings are trickier. Michigan case law holds that continued at-will employment can be enough consideration on its own, which means your employer doesn’t have to give you a raise, bonus, or promotion to get a signature. That’s a harder rule than some states use. A court can still look at the surrounding circumstances, and an agreement signed under duress or with no meaningful benefit will get closer scrutiny.
What Can Invalidate a Non-Compete
Even with blue-penciling, non-competes do fail. The most common grounds:
- No legitimate business interest. If the employer can’t identify a specific interest being protected, the agreement has no foundation. A general desire to block competition doesn’t qualify.
- Public policy. Courts will refuse to enforce an agreement that would keep someone from earning a living in their field, create a local monopoly, or harm the public. This comes up most in healthcare and other essential services.
- Vague or ambiguous terms. If the restricted activities, territory, or duration aren’t clearly defined, a court may have nothing to enforce.
- Employer breach. If the employer breached the underlying employment agreement or terminated the employee in bad faith, courts are less inclined to enforce the non-compete.
What Happens If You Violate One
The immediate threat is an injunction: a court order telling you to stop the competing work. Employers routinely seek temporary restraining orders and preliminary injunctions early in a case, sometimes within days of filing. For a preliminary injunction, the employer has to show irreparable harm without it, a likelihood of winning on the merits, that the harm to the employer outweighs the harm to the employee, and that the public interest isn’t damaged.2Michigan Courts. Business Court Opinion, C17-2025-20949-CBB Injunctions are technically an extraordinary remedy, but non-compete cases are one of the areas where courts grant them most, because ongoing competitive damage is hard to measure in dollars.
On top of that, employers can pursue monetary damages: lost profits, diverted customers, and the cost of mitigating the harm. Some agreements include liquidated damages provisions, and Michigan courts will enforce them when the amount is reasonable. In St. Clair Medical PC v. Borgiel (2006), for example, the Michigan Court of Appeals upheld a $40,000 liquidated damages provision triggered by a physician’s violation of a non-compete. If the agreement contains a fee-shifting clause, the employer may also recover attorney fees.
Situations Where the Rules Are Different
MCL 445.774a governs the employer-employee relationship. Several related situations sit outside it, and it’s worth knowing which one applies to you.
Independent contractors. If you signed as a contractor rather than an employee, the agreement is analyzed under Michigan’s broader antitrust rule of reason in MCL 445.772. The focus shifts to whether the restraint unreasonably restricts trade.
Business sales. Non-competes tied to the sale of a business get the most favorable treatment. Michigan courts almost uniformly enforce them, even terms that would look overbroad in an employment context, because the seller was paid for the goodwill the buyer is now trying to protect. The Michigan Supreme Court also confirmed in Innovation Ventures v. Liquid Manufacturing (2016) that MCL 445.774a does not apply to non-competes between business entities.3Michigan Senate Fiscal Agency. Locked In or Locked Out? An Overview of Noncompete Agreements and Their Regulation
Physicians. Doctors are covered by the same MCL 445.774a framework but face extra scrutiny because of the public interest. Courts may weigh local demand for the specialty, whether other providers offer similar care, and whether enforcement would leave patients without options.
Non-solicitation and nondisclosure clauses. These aren’t non-competes. A non-solicitation clause bars you from contacting the employer’s customers or recruiting its employees but doesn’t stop you from working for a competitor. Michigan courts generally view these more favorably. Nondisclosure agreements, which restrict sharing confidential information, are treated as even less burdensome and are routinely upheld when the information genuinely qualifies as confidential. If your employment agreement contains all three, a court could void the non-compete and still enforce the other two.
The Federal Non-Compete Ban That Never Took Effect
In 2024, the Federal Trade Commission issued a rule that would have banned most non-competes nationwide. It never took effect. A federal district court in Texas vacated it in August 2024, finding the FTC lacked authority. On September 5, 2025, the FTC voted 3-1 to accede to the vacatur and dismissed its appeals.4Federal Trade Commission. Federal Trade Commission Files to Accede to Vacatur of Non-Compete Clause Rule
For Michigan workers, that means there is no federal ban. Your non-compete is governed entirely by Michigan state law under MCL 445.774a. The FTC has said it may pursue individual enforcement actions against agreements it views as anticompetitive, but the categorical prohibition is gone.
Challenging Your Non-Compete
If you want to test enforceability, start with a Michigan employment attorney reviewing the specific language. The reasonableness analysis is fact-intensive, and the answer turns on your actual role, the information you had access to, where the employer operates, and how the restriction affects your ability to work.
Negotiation is often worth trying before litigation. Many employers will agree to shorten the duration, shrink the geography, or carve out certain work rather than pay to litigate, especially when the original agreement is clearly overbroad and a court would trim it anyway.
If negotiation fails, litigation is the remaining option. You’d argue the agreement fails the reasonableness test, lacks consideration, or violates public policy. Factor in the blue-penciling risk from the start: proving the agreement is overbroad doesn’t guarantee freedom, because the court can narrow it and still enforce it. That possibility changes the math on whether to fight or negotiate.
