Enforcement of restrictive covenants runs on a predictable track: the party seeking to enforce must show the agreement protects a legitimate interest and is reasonable in duration, geography, and scope, then prove a breach through a process that typically begins with a demand letter and can escalate to an emergency court order within days. Whether the restriction sits in an employment contract or a real estate deed, the enforcing side carries the burden, and the analysis turns on the law of the state where the restricted party actually lives and works.
What the Covenant Itself Must Establish
Before a court looks at the alleged breach, it looks at the agreement. Three requirements decide whether the covenant is even enforceable.
The first is a protectable interest. For employers, that usually means trade secrets, confidential customer relationships, or specialized training that gave the employee a competitive edge. In real estate, it typically means preserving property values and the character of a development. Without a genuine protectable interest, the restriction is arbitrary and courts will not uphold it.
The second is reasonableness across three dimensions: how long the restriction lasts, how wide a geographic area it covers, and what activities it prohibits. A non-compete barring a sales representative from working anywhere in North America for ten years will almost certainly fail. A two-year restriction covering the specific metro area where the employee had client relationships looks very different from a blanket nationwide ban. Courts ask whether the restriction goes further than necessary to protect the underlying interest.
The third is consideration. The person accepting the restriction must have received something of value in return. For new hires, the job itself usually counts. For existing employees asked to sign mid-employment, the analysis gets harder. Some jurisdictions require additional consideration beyond continued employment, such as a promotion, bonus, or access to proprietary information. If the employee signed under pressure with nothing new in return, the covenant may lack the bargain that makes a contract binding.
When a covenant is legitimate but overbroad, what happens next depends on jurisdiction. Roughly 35 states permit some form of judicial modification, letting a judge shrink a five-year restriction to two years or narrow a nationwide scope to a single region. A smaller group takes a stricter approach: if any part of the covenant is unreasonable, the whole provision fails and the court will not rewrite the contract. That distinction matters when you decide whether to sue on a covenant that pushes the edges.
Covenants That May Be Void Before You Start
The threshold question is whether the state where the restricted party works even allows the type of covenant at issue. California, Oklahoma, North Dakota, and Minnesota prohibit most non-compete agreements outright. In those states, a non-compete signed as a condition of employment is generally void regardless of how narrowly it was drafted. Non-solicitation and confidentiality agreements may still be enforceable, but employers there must rely on trade secret law and other tools when it comes to competition itself.
Several other states have enacted significant restrictions short of a full ban. Some require garden leave, meaning continued compensation during the restricted period. Others cap the allowable duration, require the agreement to be signed before or at the start of employment, or exempt workers earning below a salary threshold. These rules have been shifting quickly, so enforceability depends on the law in effect at the time of enforcement, not just when the agreement was signed.
On the federal side, the FTC’s 2024 rule that would have banned most non-competes is not in effect. A federal district court blocked it, and in September 2025 the Commission voted 3-1 to dismiss its appeals and accept the decision striking the rule down.1Federal Trade Commission.

How an Enforcement Action Actually Moves
The Demand Letter
Enforcement typically begins with a cease-and-desist letter. It is not a court filing, but a formal demand that puts the other side on notice and creates a paper trail. A well-drafted letter identifies the specific covenant terms being violated, describes the evidence, and gives the recipient a short window, usually 10 to 30 days, to come into compliance. Many disputes resolve here, because the letter signals seriousness and shows that evidence is already assembled. If it does not resolve, the letter becomes Exhibit A in the lawsuit.
Temporary Restraining Orders
When a former employee is actively soliciting clients or already working for a direct competitor, waiting months for a trial is not realistic. The enforcing party can ask the court for a temporary restraining order, which can be granted within days of filing and sometimes without the other side present. A TRO is a stopgap. Under the federal rules, it expires after 14 days unless extended for an additional 14 days or the restrained party consents to a longer period.4Office of the Law Revision Counsel.

The Preliminary Injunction Hearing
A preliminary injunction hearing, usually scheduled within two to four weeks of the TRO, is where the real fight happens. The party seeking the injunction must show four things: a likelihood of winning on the merits, a likelihood of irreparable harm without the injunction, that the balance of hardships tips in their favor, and that an injunction serves the public interest. Some states presume irreparable harm when a valid non-compete is breached, which eases the employer’s burden on that factor. In other jurisdictions, the employer must independently prove that money damages will not make it whole.
The court can require the party obtaining the injunction to post a bond covering the restrained party’s damages if the injunction turns out to have been wrongly granted.4Office of the Law Revision Counsel.

Timeline and Cost
After the preliminary injunction phase, the case moves through standard civil litigation: discovery, depositions, pre-trial motions, and potentially trial. Most restrictive covenant cases resolve within six to twelve months, often through settlement after the preliminary injunction ruling gives both sides a clear read on how the judge sees the merits. Attorney fees and forensic costs through the preliminary injunction phase alone can exceed $100,000, and complex cases involving trade secrets or multiple defendants run considerably higher. That cost reality drives many settlements and explains why employers pursue enforcement selectively, usually against departures that pose the greatest competitive threat.
Building the Proof of Violation
Proving a breach requires specific, documented evidence tying conduct to contract terms. In employment cases, the strongest evidence tends to be digital: server logs showing bulk downloads of client files before a departure, email correspondence with a competitor during the restricted period, or a LinkedIn update announcing a new role that falls squarely within the prohibited scope. Payroll records or a job description from the new employer can establish that the former employee’s duties overlap with what the covenant restricts.
Property covenant violations are more straightforward. Photographs of unauthorized construction, unpermitted outbuildings, or exterior changes that violate architectural guidelines provide concrete proof. Written correspondence with the homeowners association, especially ignored warning letters, establishes that the violation was knowing rather than accidental. Organizing this evidence chronologically, with dates and document sources, is what separates a complaint that reads as a grievance from one that reads as a documented breach.
Once a dispute is reasonably anticipated, both sides have an obligation to preserve relevant documents and data. Destroying evidence after litigation becomes foreseeable, known as spoliation, can trigger sanctions ranging from cost-shifting to a jury instruction that the destroyed evidence was unfavorable, up to a default judgment in the worst cases. Anyone contemplating enforcement should issue an internal litigation hold, preserving all communications, access logs, and documents related to the covenant and the restricted party.
What a Court Can Order
The most common remedy is an injunction, preliminary or permanent, ordering the violating party to stop the prohibited activity. A permanent injunction follows final judgment and can last for the remainder of the covenant’s term or, in real estate cases, indefinitely. Courts shape orders to the specific violation, so a former employee might be barred from contacting particular clients rather than from all employment in the industry.
Financial compensation fills the gap when an injunction alone cannot undo the damage. If the contract includes a liquidated damages clause setting a specific amount or formula, courts will enforce it when the number represents a reasonable estimate of anticipated losses rather than a penalty. Without such a clause, the enforcing party must prove actual damages through financial records connecting the breach to a measurable decline, such as lost revenue from diverted clients or the cost of restoring a property to compliance.
Many restrictive covenant agreements also include a provision requiring the losing party to pay the winner’s attorney’s fees. These clauses are overwhelmingly one-directional: the employee pays if they lose, but the employer does not pay if the employee successfully defends. In most states, one-way fee-shifting is enforceable. Only a small number of jurisdictions imply reciprocity. If you are on the receiving end of an enforcement action, check for a fee-shifting clause first, because it changes the risk calculus of fighting versus settling.
Defenses That Derail Enforcement
Even a well-drafted covenant can fail against a strong defense. The person facing enforcement has several available:
- Lack of consideration. If an existing employee was asked to sign a non-compete without receiving anything new, the agreement may lack the consideration needed to form a binding contract. Simply continuing to show up to work is often not enough where independent consideration is required.
- Material change in employment terms. Courts in some jurisdictions have refused to enforce non-competes when the employer substantially changed the position, cut compensation, or reassigned the employee’s territory after signing.
- Termination without cause. When an employer fires someone without cause and then tries to enforce a non-compete, courts sometimes find it inequitable to restrict the former employee’s ability to earn a living.
- Waiver. If the employer knew about the violation and did nothing for an extended period, the restricted party can argue the right to enforce was waived through prolonged inaction.
- Laches. Unreasonable delay in bringing the claim, combined with prejudice to the other party who changed position in good faith (like investing in a new business or relocating), can defeat equitable relief.
- Unclean hands. A party seeking equitable relief must come to court with clean hands. Misrepresenting the covenant’s scope or breaching one’s own contractual obligations related to the agreement can lead a court to deny the requested remedy.
These defenses stack. An employer who fired an employee without cause, waited eight months, then sued to enforce a non-compete is compounding weaknesses: the termination undermines the covenant’s fairness, the delay supports both waiver and laches, and any interim retaliatory conduct could trigger unclean hands. Enforcement is far from automatic even when the covenant language looks airtight.
Arbitration Clauses and Choice-of-Law Provisions
Many employment agreements pair restrictive covenants with mandatory arbitration clauses. Under the Federal Arbitration Act, challenges to the enforceability of the substantive contract terms, including the restrictive covenants themselves, generally must be decided by the arbitrator rather than a court. Some agreements carve out an exception allowing the employer to seek temporary injunctive relief from a court before or during arbitration, preserving access to an emergency TRO. Without that carve-out, an employer may find itself unable to get fast court relief when speed matters most.
Choice-of-law provisions add another layer. Employers often designate a particular state’s law to govern, typically choosing one with enforcement-friendly rules. Courts generally honor these provisions, but not always. If the chosen state’s law conflicts sharply with the public policy of the state where the employee actually works, the local court may refuse to apply it. Drafting to survive under the law of the state where the employee is actually based is the safer route.
Filing Deadlines
Restrictive covenant claims are subject to statutes of limitations that vary by state, typically four to six years for breach of a written contract. The clock generally starts running when the breach occurs, not when the contract was signed. Waiting too long does more than weaken your case strategically through laches and waiver arguments. Miss the statute of limitations entirely and the claim is dead regardless of the evidence. In fast-moving situations where a former employee is actively competing, the practical deadline is far shorter than the legal one, because delay erodes both your position in court and the competitive damage you are trying to prevent.
