Texas non-compete agreement: how Business and Commerce Code §15.50 works, the ancillary-to-otherwise-enforceable-agreement requirement, the reformation doctrine that rewrites overbroad covenants, and why Texas is more complicated than it looks

Texas enforces non-competes, but with a catch

Texas is frequently described as an employer-friendly state for non-compete enforcement, and in practice it mostly is. But the statutory framework is more nuanced than that reputation suggests, and the "ancillary to an otherwise enforceable agreement" requirement creates genuine enforceability questions that don't exist in states that apply a pure reasonableness test.

The governing statute is Texas Business and Commerce Code §15.50, part of the Covenants Not to Compete Act. It provides that a covenant not to compete is enforceable if it is "ancillary to or part of an otherwise enforceable agreement at the time the agreement is made" and contains limitations as to time, geographical area, and scope of activity that are reasonable and do not impose a greater restraint than is necessary to protect the goodwill or other business interest of the promisee.

Two requirements, both of which must be satisfied. The non-compete must be ancillary to an otherwise enforceable agreement. And the restrictions must be reasonable in time, geography, and scope. The second requirement is familiar from other states' reasonableness frameworks. The first is Texas-specific and has generated substantial litigation.

The ancillary requirement

The phrase "ancillary to or part of an otherwise enforceable agreement" is the heart of Texas non-compete law. It means the non-compete can't stand alone — it must be attached to a separate agreement that provides independent consideration and is itself enforceable.

What counts as the "otherwise enforceable agreement"? The Texas Supreme Court addressed this directly in Alex Sheshunoff Management Services, L.P. v. Johnson (2009) 209 S.W.3d 644, holding that the consideration giving rise to the employer's interest in restraining the employee from competing must be reasonably related to the interest the covenant is designed to protect. In plain terms: the employer must give the employee something that creates the business interest the non-compete protects.

The most common forms of qualifying consideration in Texas practice:

Access to confidential information or trade secrets. If the employer provides the employee with access to proprietary information, customer lists, pricing data, or trade secrets as part of the employment relationship, and the non-compete is designed to protect that information, the ancillary requirement is satisfied. This is the most frequently litigated basis because nearly every employer argues that the employee received confidential information, and the question is whether what was provided actually qualifies.

Stock options or equity grants. In Marsh USA Inc. v. Cook (2011) 354 S.W.3d 764, the Texas Supreme Court held that stock options granted after the beginning of employment — not just at hiring — can serve as the "otherwise enforceable agreement" that supports a non-compete. This was significant because it meant employers could add non-competes to existing employment relationships by tying them to equity awards, even for employees who had been working without a non-compete.

Specialized training. If the employer invests in substantial specialized training that goes beyond general job skills, the training commitment can support a non-compete designed to protect that investment. The training must be genuinely specialized — routine onboarding or industry-standard certification doesn't qualify.

Signing bonuses, retention bonuses, and similar payments. Financial consideration tied to the non-compete can satisfy the ancillary requirement, though the relationship between the consideration and the competitive restriction must be reasonable.

What doesn't qualify. At-will employment alone — the promise of a job — does not constitute an "otherwise enforceable agreement" in Texas. This is where Texas differs from states that treat initial employment as sufficient consideration for a non-compete signed at hiring. In Texas, the employer must point to something beyond the employment relationship itself. In practice, most employers satisfy this by including confidentiality provisions or equity awards in the same agreement, which then serves as the otherwise enforceable agreement to which the non-compete is ancillary.

The reasonableness analysis

Once the ancillary requirement is met, the non-compete must still be reasonable in time, geography, and scope. Texas courts apply a conventional reasonableness framework, but the specific benchmarks are shaped by Texas case law.

Duration. Texas courts have upheld non-competes lasting one to two years in most employment contexts. Three years has been upheld in some cases involving senior executives with deep client relationships. Five years is likely unreasonable for an employment non-compete, though longer periods may survive in the sale-of-business context.

Geographic scope. The restriction must correspond to the area where the employer does business or where the employee performed work. A statewide restriction is reasonable if the employee worked across the state. A nationwide restriction is reasonable if the employer competes nationally and the employee's role was national in scope. An overbroad geographic restriction — say, restricting a Dallas-based regional sales rep from competing anywhere in North America — is unreasonable, but in Texas, that doesn't mean the entire non-compete falls.

Scope of activity. The restriction should be limited to competitive activity, not to all employment at a competitor. A non-compete that prevents an employee from performing any function at a competing company — including functions unrelated to the employer's protectable interest — is overbroad. A restriction limited to the same role or the same client set is more defensible.

Protectable business interest. The restriction must protect something real. Texas recognizes trade secrets, confidential proprietary information, customer goodwill, and specialized training as protectable interests. The employer's general desire to prevent competition is not a protectable interest. The non-compete must be drawn to protect the specific interest identified, not to broadly suppress competitive activity.

The reformation doctrine: why Texas employers rarely lose entirely

Here's where Texas diverges from employee-friendly jurisdictions in a meaningful way. Under §15.51(c), if a court finds that a covenant not to compete is unreasonable in scope, the court "shall reform the covenant to the extent necessary to cause the limitations contained in the covenant as to time, geographical area, and scope of activity to be reasonable" and shall enforce the covenant as reformed.

The word is "shall," not "may." If the non-compete is overbroad, the court doesn't void it — the court rewrites it to be reasonable and then enforces the rewritten version. This is mandatory reformation, and it fundamentally changes the employer's risk calculus.

In a strict blue-pencil state like New York, an employer who overreaches risks losing the entire covenant. The employer therefore has an incentive to draft narrowly. In Texas, an employer who overreaches gets a court-imposed correction at no cost. The employer's worst-case outcome in a reformation state is the same restriction they would have gotten if they'd drafted reasonably in the first place. There's no penalty for overreaching.

The practical effect: Texas non-compete litigation often isn't about whether the restriction will be enforced, but about what the court will reform it to. Employees challenging overbroad non-competes in Texas should expect that the court will narrow the restriction rather than eliminate it. The strategic question is what the reformed restriction will look like and whether that reformed restriction meaningfully limits the employee's next move.

There is one important limit on reformation. The court can only reform restrictions that exist in the original agreement. If the non-compete contains no geographic restriction at all, the court can't insert one. Reformation modifies existing terms — it doesn't create new ones from scratch. This occasionally matters when employers use poorly drafted template agreements that omit key terms.

The physician exception

Texas has a specific statutory exception for physicians. §15.50(b) provides that a non-compete against a physician is enforceable only if it does not deny the physician access to a list of patients seen or treated within the last five years, does not prevent the physician from providing continuing care to patients during the course of an acute illness, and requires the employer to offer reasonable buy-out terms for the non-compete.

This doesn't void physician non-competes — it imposes additional requirements. Texas physicians can be bound by non-competes, but the agreement must preserve continuity of patient care and provide a buyout option. The buyout provision is particularly significant: it means a physician can always exit a non-compete by paying, which changes the economic calculus considerably.

At-will employment and the timing problem

Most Texas employees are at-will, meaning either party can end the relationship at any time for any lawful reason. This creates a tension with non-compete enforcement: if the employer can fire the employee at any time for any reason, and the non-compete then prevents the fired employee from working for a competitor for two years, the employee bears the full burden of the restriction without any guaranteed benefit.

Texas courts have recognized this tension but haven't resolved it by voiding non-competes for at-will employees. Instead, the ancillary requirement does some of the work — the employer must point to consideration beyond employment itself. And the reasonableness analysis theoretically accounts for the hardship that enforcement would impose on a terminated employee.

But in practice, the reformation doctrine limits how much relief the hardship argument provides. Even if a court finds that the restriction is unreasonable as applied to a terminated employee, the court reforms it rather than voiding it. The employee may get a shorter duration or a narrower scope, but they rarely get out entirely.

The practical enforcement landscape

Texas employers enforce non-competes regularly. The state's courts are accustomed to these cases, the legal framework is well-developed, and the reformation doctrine gives employers confidence that litigation is worth pursuing even when the original agreement is imperfect.

Enforcement typically begins with a cease-and-desist letter to the departing employee and often to the new employer as well. If the employee doesn't comply, the employer moves for a temporary restraining order and preliminary injunction. Texas courts can and do grant injunctive relief in non-compete cases, though the employer must demonstrate a probable right to recovery, a probable injury if the injunction isn't granted, and no adequate remedy at law.

The cost of enforcement matters. Non-compete litigation in Texas typically costs $20,000 to $100,000 or more through preliminary injunction, depending on complexity. Employers are most likely to pursue enforcement against senior employees with access to trade secrets, significant client relationships, or both. For lower-level employees, the cost of enforcement often exceeds the value of the restriction, and the non-compete serves primarily as a deterrent.

What Texas employees should know

If you signed a non-compete in Texas, it's likely enforceable — but the specifics matter. The ancillary requirement creates real enforceability questions that don't exist in pure-reasonableness states. If the only consideration you received was the job itself, with no confidentiality agreement, no equity, and no specialized training, the non-compete may fail at the threshold.

If the non-compete passes the ancillary test but overreaches on time, geography, or scope, expect reformation rather than invalidation. The court will narrow the restriction, not eliminate it. Your strategic goal in that situation isn't to void the agreement — it's to shape what the reformed version looks like.

If you're a physician, you have specific statutory protections including a mandatory buyout option.

If your employer is based in another state but you work primarily in Texas, the choice-of-law analysis matters. Texas courts will generally apply Texas law to employment relationships performed in Texas, but choice-of-law provisions can complicate this. If your agreement designates another state's law — particularly a more employer-friendly state like Florida — the validity of that designation is a threshold issue.

If you're considering a job change and you're subject to a Texas non-compete, the FTC's decision not to pursue a federal ban means there's no cavalry coming from Washington. The analysis is Texas law, your specific agreement, and the practical question of whether your current employer will spend the money to enforce.
