A promise whose performance would limit competition in any business or restrict the promisor in the exercise of a gainful occupation.

Overbroad Noncompete After Client-Book Sale
Rosa Ruiz sold her entire book of brokerage clients to Regal Apparel. The agreement barred her for five years from serving any wealth-management client nationwide. When Rosa began working at a local bank, Regal sued to enforce the clause. The court refused enforcement because the nationwide industry-wide ban exceeded what was necessary to protect the goodwill Regal had purchased.
Antitrust Suit With Damages Counterclaim
Pinnacle Stadium sued Creek Game in federal court alleging that eligibility rules unreasonably restrained trade and suppressed player salaries. Creek Game answered with a damages counterclaim and demanded a jury trial on all issues. The district court had to decide whether the presence of the legal counterclaim entitled Creek Game to a jury on the restraint-of-trade issues even though the original complaint sought only equitable relief.

Frequently Asked

When is a promise to refrain from competition considered ancillary to a valid transaction?+
A promise is ancillary when it is made as part of an otherwise valid transaction or relationship such as the sale of a business or the formation of an employment or partnership relation. A promise made after the transaction ends or one that protects no legitimate interest of the promisee is not ancillary and is therefore unreasonable.
What test determines whether an ancillary restraint is unreasonable?+
A restraint is unreasonable if it is greater than needed to protect the promisee's legitimate interest or if the promisee's need is outweighed by hardship to the promisor and likely injury to the public. Courts examine duration, geographic scope, and the breadth of restricted activity.
Does a noncompete that is ancillary to a sale of business automatically become enforceable?+
No. Even when a noncompete accompanies a legitimate sale of a business or client book, the restraint must still satisfy the reasonableness test. A restriction that reaches far beyond the purchased goodwill in time, geography, or scope remains unenforceable.
May a court enforce the remainder of an agreement after striking an unreasonable noncompete?+
Yes. If the unenforceable restraint is not an essential part of the agreed exchange, a court may enforce the balance of the agreement while refusing to enforce only the offending promise.
