Michigan is an enforcement state. Unlike California, which voids most employee non-competes outright, Michigan permits them within statutory limits and gives judges the power to rewrite the ones that reach too far. This is one of the topics covered in the reference on Michigan labor laws. What follows is the statutory test, the factors courts weigh under it, the blue-pencil rule that keeps overbroad agreements alive in narrowed form, and how the federal picture interacts with state law.
The statute behind Michigan non-competes
Non-compete agreements sit inside Michigan’s antitrust law rather than its employment code. The general rule in Mich. Comp. Laws § 445.772 is that a contract in restraint of trade in a relevant market is unlawful. Employee non-competes restrain trade by definition, so without an exception they would fall under that prohibition.
The exception is Mich. Comp. Laws § 445.774a. It permits an employer to obtain from an employee “an agreement or covenant which protects an employer’s reasonable competitive business interests” and prohibits post-employment competition, provided the agreement “is reasonable as to its duration, geographical area, and the type of employment or line of business.”
That sentence carries the entire test. Three elements have to hold: the employer has a competitive business interest worth protecting, the agreement is aimed at protecting that interest, and each of the three dimensions is reasonable.
Timing matters for older agreements. Section 4a applies to covenants entered into after March 29, 1985, and the section itself was added by 1987 Public Act 243, according to the text and history of § 445.774a. Agreements signed before that date fall outside the statutory permission.
What makes a Michigan non-compete reasonable
The statute names the dimensions but assigns no numbers to them. Michigan courts fill in the content case by case, which means a duration that survives in one industry can fail in another.
Reasonable competitive business interest. An employer’s interest in confidential pricing, customer lists, trade secrets, specialized training it paid for, or goodwill built with clients is the kind of interest the statute contemplates. An interest in preventing ordinary competition, standing alone, is not. This is the threshold question, and an agreement that protects nothing beyond the employer’s general dislike of competition has trouble at the first step.
Duration. Shorter restrictions are easier to defend than longer ones. The relevant question is how long the protected information stays valuable or how long it takes the employer to rebuild a customer relationship. A restriction that outlasts the shelf life of the information it guards is vulnerable.
Geographic area. The area typically tracks where the employee actually worked or where the employer actually competes. A statewide or nationwide restriction imposed on someone who served three counties is the classic overbreadth problem.
Type of employment or line of business. The restriction should reach the work the employee did, not every role at every competitor. A clause barring a former sales representative from any position in the industry, including unrelated work, reaches beyond the interest it claims to protect.
How Michigan courts narrow an overbroad agreement
Michigan uses what practitioners call the blue-pencil rule, and the statute states it directly. Under Mich. Comp. Laws § 445.774a(1), where a covenant “is found to be unreasonable in any respect, a court 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.”
The practical effect is significant. In states without this rule, an overbroad clause can be unenforceable in full, and the employee walks away unrestricted. In Michigan, a judge who finds a five-year nationwide restriction excessive has the option of reducing it to a shorter term over a smaller area and enforcing what remains.
The power is discretionary. The statute says a court “may” limit the agreement, not that it must. How far a court will go to rescue a clause that was drafted far beyond any defensible scope is an open question that turns on the circumstances in which the agreement was made.
Non-competes attached to the sale of a business
A covenant given by a seller to a buyer of a business is a different arrangement from one imposed on an employee, and courts treat it differently in practice. The buyer is paying for goodwill, and a promise by the seller not to reopen across the street is part of what was purchased.
Section 4a by its terms addresses agreements an employer obtains from an employee. Sale-of-business covenants are analyzed under the broader restraint-of-trade framework in the Michigan Antitrust Reform Act, where the consideration paid and the seller’s role in the transferred goodwill bear on reasonableness. Restrictions that would look aggressive in an employment contract are more defensible when they accompany a purchase price.
Agreements that blend the two situations are common. An owner who sells a company and stays on as an employee may sign both a sale covenant and an employment covenant, and the two can carry different terms and different analyses.
Where the federal noncompete rule stands
In 2024 the Federal Trade Commission adopted a rule that would have barred most employee non-competes nationwide and required employers to notify workers that existing clauses would not be enforced. The rule did not take effect, and the FTC’s noncompete rule page carries the agency’s current status information.
As of 2026, Michigan employers and employees are governed by state law on this question. The federal agency retains other tools against restrictive employment terms, including case-by-case enforcement, so a covenant that survives the state reasonableness test is not automatically insulated from federal scrutiny.
What an enforcement lawsuit looks like
Non-compete fights usually start when a former employee takes a job the covenant appears to cover. The employer’s first move is typically a cease-and-desist letter to the employee, the new employer, or both. Litigation follows when the letter does not resolve the dispute.
A complaint is filed in circuit court
The employer files in the Michigan circuit court for a county with a connection to the parties or the conduct. The complaint usually pleads breach of contract along with related claims such as misappropriation of trade secrets or breach of the duty of loyalty.
The employer asks for an injunction
Because money damages are hard to measure while competition is ongoing, employers commonly seek a temporary restraining order or preliminary injunction to halt the disputed work while the case proceeds. Injunction practice is where most non-compete disputes are effectively decided.
Reasonableness is litigated
Both sides put on evidence about the employer’s protectable interest, the employee’s actual duties and territory, and the scope of the new job. The court applies the statutory reasonableness test to those facts.
The court enforces, narrows, or declines to enforce
A court that finds the covenant reasonable enforces it as written. A court that finds a term unreasonable can narrow the covenant and enforce the reduced version. A court that finds no protectable interest declines to enforce at all.
Published Michigan Court of Appeals and Supreme Court decisions applying the statute are searchable through the judiciary’s case, opinion, and order search. Opinions in this area are fact-specific, so the reasoning in a decision matters more than the particular number of months or miles it approved.
A non-compete dispute often runs alongside other separation questions that have their own timetables, including the deadlines in Michigan final paycheck law. Those obligations are independent of the covenant and are not suspended while an enforcement case is pending.
Frequently asked questions
Can a Michigan employer add a non-compete after someone is already hired?
Michigan contract law requires consideration for a new promise. Employers commonly present mid-employment covenants alongside a raise, a promotion, a bonus, or continued employment, and whether continued employment alone supplies adequate consideration is a recurring question given that Michigan is an at-will employment state. The reasonableness test in Mich. Comp. Laws § 445.774a applies to a mid-employment covenant the same way it applies to one signed at hiring.
What is the difference between a non-compete and a non-solicitation agreement?
A non-compete restricts where and in what capacity a former employee can work. A non-solicitation clause is narrower: it bars contacting the former employer’s customers, employees, or both, while leaving the person free to take a competing job. Because a non-solicitation clause restrains less activity, it is generally easier to defend as reasonable, though it is still measured against the same statutory framework.
Does a non-compete survive a layoff or a firing?
The statute does not distinguish between employees who quit and employees who are terminated, and the enforceability of a covenant after an involuntary separation is argued case by case in Michigan. Some agreements address the question directly by stating that the restriction lapses if the employer ends the relationship without cause. A separation that was itself unlawful raises a separate set of claims, covered in wrongful termination in Michigan.
Can a Michigan non-compete stop someone from working in another state?
It depends on the covenant’s geographic terms and on which state’s law governs the contract. Many agreements contain a choice-of-law clause selecting Michigan and a forum clause selecting a Michigan court. A restriction covering territory where the employer does not compete and the employee never worked runs into the geographic-reasonableness requirement regardless of the state named in the clause.
Is a non-compete signed in Michigan before 1985 still binding?
Section 4a applies by its terms to covenants entered into after March 29, 1985, as stated in Mich. Comp. Laws § 445.774a(2). Covenants predating that line do not draw on the statutory permission and are analyzed under the law that applied when they were made.
Does the employee pay the employer’s legal fees in a non-compete case?
Michigan follows the American rule, under which each side bears its own attorney fees unless a statute or a contract shifts them. Many non-compete agreements include a fee-shifting clause that awards fees to the prevailing party or specifically to the employer. Whether such a clause is enforceable in a given case is decided by the court hearing the dispute.
