A non-compete agreement in a business sale is enforceable when its duration, geographic reach, and the activities it prohibits are each no broader than necessary to protect the goodwill the buyer paid for. Courts give these covenants substantially more latitude than non-competes signed by employees, because the seller chose to sell, received real money for the promise, and bargained at roughly equal footing. The practical question is almost never whether the covenant can exist, but whether its specific terms reach further than the deal justifies.
Why Sale Covenants Get More Deference Than Employment Ones
A large share of the purchase price in most business sales reflects goodwill: customer relationships, brand recognition, and market presence that make the business worth more than its tangible assets. If the seller could close on Friday and open a competing shop on Monday, that goodwill disappears. The non-compete prevents that outcome, and courts recognize the buyer’s need to protect the investment.
For the covenant to work, it has to be “ancillary” to the sale, meaning it supports the larger transaction rather than standing alone as a restraint on trade. The Federal Trade Commission has noted that even ancillary provisions must be “reasonably necessary for accomplishing the benefits of the transaction, and narrowly tailored to the circumstances surrounding the transaction.”1Federal Trade Commission. Just Because It’s Ancillary Doesn’t Make It Legal The purchase price itself is the legal consideration: the seller agrees not to compete in exchange for the money received.
That transactional context explains the lighter judicial touch. An employee signing a non-compete at hiring often has little leverage, may not grasp the restriction, and typically receives no separate payment for the promise. A business seller is a sophisticated party who negotiated the terms and received real value. Even states that heavily restrict or ban non-competes in employment generally preserve an exception for sales, because without the ability to restrict the seller’s re-entry, buyers would pay less or walk away entirely.
The Reasonableness Test
Every court evaluating one of these covenants applies some version of a reasonableness analysis. The agreement must protect a legitimate business interest without reaching further than necessary. Three parameters drive the outcome, and overreach on any one of them puts the whole covenant at risk.
Duration
The restriction must last long enough for the buyer to absorb the acquired goodwill but not so long that it becomes punitive. Three to five years is commonly upheld in the sale context, and the Seventh Circuit has specifically found a five-year period reasonable. A two-year restriction is almost always safe. Beyond five years, skepticism grows, particularly in fast-moving industries where customer loyalty shifts quickly.
The right number depends on how long it realistically takes the buyer to cement relationships with the acquired customer base. If the business runs on long-term contracts that renew every three years, five years gives the buyer time to get through at least one renewal cycle. If customers decide monthly and switch providers easily, even three years may be more than needed.
Geographic Scope
The restricted territory must match the footprint where the business actually operated and generated its goodwill. The FTC has illustrated this concretely: if you sell three gas stations in Los Angeles, a non-compete covering all of California for seven years is “unduly broad,” but a restriction limited to a one- or two-mile radius around each station for a couple of years “appears more tailored.”1Federal Trade Commission. Just Because It’s Ancillary Doesn’t Make It Legal
The territory can be defined by a radius around the business location, by listing specific counties or states, or by referencing the area where the business had active customers. A genuinely national e-commerce business may support a nationwide restriction. If the seller’s online sales were concentrated in a dozen states, the restriction should stop at those states. Geographic scope has to track the purchased goodwill, not a wish list of markets the buyer hopes to enter someday.
Scope of Prohibited Activity
The covenant can only restrict activities that actually compete with the business being sold. If the acquired business was commercial plumbing, it cannot stop the seller from opening a residential landscaping company. A restriction broad enough to lock the seller out of every imaginable line of work will fail.
Precision matters. Vague language like “any similar business” invites litigation and can lead a court to void the clause. The better approach is to describe the prohibited activities with enough specificity that both sides know exactly where the line falls. If the business manufactures industrial valves, say that; don’t say “manufacturing” and leave the rest to interpretation.
Non-Solicitation Clauses
Most well-drafted sale agreements pair the non-compete with a separate non-solicitation clause. While the non-compete keeps the seller out of the market, the non-solicitation clause targets a narrower problem: the seller reaching out directly to former customers or recruiting key employees away from the business just sold.
Courts view non-solicitation provisions as less restrictive and are more willing to enforce them. A non-solicitation clause sometimes survives even when the accompanying non-compete is struck down as overbroad. These clauses typically run 12 to 36 months and prohibit the seller from initiating contact with identified customers or employees. The seller can usually still do business with a former customer who reaches out on their own.
What Happens When the Covenant Is Too Broad
An overbroad covenant does not automatically free the seller. What happens next depends heavily on the state where the dispute is litigated, because courts take three fundamentally different approaches.
Most states use a reformation approach. The court rewrites unreasonable terms to make them enforceable. If a five-year restriction covering all of Texas should have been three years covering the Dallas–Fort Worth metro area, the court narrows it. This is the most buyer-friendly rule, because even a poorly drafted covenant still provides some protection.
A smaller group of states follows the traditional “blue pencil” doctrine. The court can strike unreasonable provisions but cannot rewrite them. If deleting the bad language leaves something coherent, the covenant survives in reduced form. If the deletion leaves an incoherent mess, the whole covenant fails.
A handful of states apply the “red pencil” or “all or nothing” rule. If any part of the non-compete is unreasonable, the entire covenant is void. Nebraska, Virginia, Wisconsin, and Wyoming generally follow this approach. In those states, precision is survival. An overreach on geography can destroy the whole restriction, including duration and activity limits that were perfectly reasonable on their own.
The practical takeaway is that in a reformation state, a somewhat aggressive covenant carries less risk because the court will fix it. In a red-pencil state, the drafter needs to be conservative from the start. Knowing which rule applies in the relevant jurisdiction should shape the negotiation before the ink dries.
Remedies When the Seller Breaches
When a seller violates the covenant, the buyer’s most effective remedy is usually injunctive relief rather than money damages. Lost goodwill and diverted customers are hard to quantify, and by the time a damages calculation works through trial, the harm may be irreversible.
Injunctive Relief
Courts can issue a temporary restraining order or preliminary injunction to stop the seller’s competitive activity while the case is pending. To get that relief, the buyer generally must show four things: a likelihood of winning on the merits, that irreparable harm will result without the injunction, that the balance of hardships favors the buyer, and that the injunction serves the public interest. The irreparable harm element is usually the linchpin. Because goodwill erosion is hard to measure in dollars, courts often accept that a proven breach causes the kind of injury money alone cannot fix.
Monetary Damages
The buyer can also pursue lost profits caused by the seller’s competition. These claims get difficult. The buyer needs to show a causal connection between the seller’s actions and specific revenue losses, which almost always requires expert testimony comparing actual performance against projected performance without the breach. If the business was already declining for unrelated reasons, isolating the damage attributable to the seller becomes a serious evidentiary challenge.
Liquidated Damages
Some agreements include a liquidated damages provision that sets a predetermined payment for breach. These clauses spare the buyer from proving actual damages, but they hold up only if the amount was a reasonable forecast of the harm at the time of contracting and actual damages would be difficult to calculate. A stipulated figure grossly disproportionate to any plausible harm will be treated as an unenforceable penalty. When courts are on the fence, they tend to call an ambiguous provision a penalty rather than legitimate liquidated damages. A well-drafted clause explains the reasoning behind the chosen amount, which helps it survive review.
The Federal Picture
In 2024, the Federal Trade Commission issued a final rule that would have banned most non-compete agreements nationwide. The rule included an explicit exception for non-competes entered in connection with a bona fide sale of a business, without any minimum ownership percentage for the seller. A federal district court found that the FTC lacked authority to issue the rule and prohibited its enforcement, and the FTC later filed to accede to the vacatur. The rule is not in effect.2Federal Trade Commission. Federal Trade Commission Files to Accede to Vacatur of Non-Compete Clause Rule
Several states have enacted their own restrictions on non-competes in recent years, and nearly all of them preserve the business-sale exception. The policy case for allowing these covenants when a business changes hands is strong enough that even the most restrictive jurisdictions leave room for them. What counts as “reasonable” still varies by state, and a covenant that would sail through in one jurisdiction may need trimming in another.
