12 Month Contact Based Non Solicitation Clauses for U.S. Employers
A non-solicitation clause stops a departing employee from actively going after your clients or your remaining staff for a set period, usually around 12 months. Courts tend to enforce it when the restriction is narrow (tied to actual client contacts, not “anyone the company has ever emailed”) and back off when it is not. The trap most businesses miss isn’t state contract law. It’s federal antitrust and labor exposure that can bite even when your clause is perfectly reasonable on paper.
TL;DR:
Non-solicitation clauses typically last around 12 months, with enforceability depending on specific language, scope, and legitimate business interests involved.
Contact-based definitions and lookback periods of 12 to 24 months are essential for clauses to withstand legal challenges, especially when restricting client or employee solicitation.
Overbroad clauses, such as banning solicitation of all clients or employees, are often narrowed or invalidated by courts, emphasizing the need for narrowly tailored language.
Employers must be cautious of federal antitrust risks, particularly with no-poach agreements between competitors, which are illegal per se and can lead to criminal liability.
Drafting and periodically reviewing non-solicitation clauses to reflect role changes and current business needs is crucial for maintaining enforceability over time.

What Is a Non-Solicitation Clause, Exactly?
A non-solicitation clause is a promise, usually buried in an employment agreement, severance package, or partnership agreement, that says: “If you leave, you won’t go poach our clients or our people.” That’s it. It doesn’t stop someone from working for a competitor. It doesn’t stop them from doing the same job somewhere else in town the next Monday. It just says they can’t actively recruit your team or chase down your customer list on the way out the door.
That distinction matters because people constantly confuse it with a non-compete. A non-compete tells someone they can’t work in the same industry, or for a competitor, or within a certain radius, for a certain amount of time. It restricts where someone can work. A non-solicit restricts who they can contact. It’s a much narrower ask, which is exactly why courts are generally friendlier to it. You’re not blocking someone’s livelihood. You’re just telling them not to raid the building on their way out.
It’s also different from a non-disclosure agreement. An NDA protects confidential information itself, like a client list, pricing formula, or product roadmap. A non-solicitation clause protects the relationships built using that information. You can have one without the other, but the strongest agreements usually pair them, along with an employee non-disparagement clause that keeps departing staff from trashing the company publicly.
Non-solicitation agreements typically cover three groups:
Employees. Barring a departing manager from recruiting the team they used to run.
Clients or customers. Barring a departing salesperson from calling accounts they personally serviced.
Vendors or suppliers. Less common, but useful when a business has negotiated favorable supplier terms that took years to build.
A software company in Austin, for example, might use an employee non-solicit to stop a departing engineering lead from gutting the team, while a consulting firm in Tampa might rely on a customer non-solicitation clause to keep a former partner from calling the same twelve clients they served for a decade.
What Do Sample Non-Solicitation Clauses Actually Say?
Generic language is where most of these clauses fall apart. “Employee shall not solicit any customer of the Company” sounds fine until a judge asks: which customers? Contacted when? Solicited how? Vague language invites a court to strike the whole thing. Specific language survives.
Employee non-solicit, sample language:
“For twelve (12) months following termination of employment, Employee shall not directly or indirectly solicit, induce, or attempt to induce any employee of the Company with whom Employee had material contact during the last twelve (12) months of employment to leave their employment with the Company.”
The phrase “material contact” and the lookback window do real work here. Without them, you’re arguably restricting contact with an intern in another department the departing employee has never spoken to, which is exactly the kind of overreach that gets clauses thrown out or narrowed by a court.
Customer non-solicit, sample language:
“For twelve (12) months following termination, Employee shall not solicit business from any customer with whom Employee had direct contact or about whom Employee received confidential information during the twenty four (24) months preceding termination.”
Notice this version is contact-based, not a blanket “all customers of the company” restriction. A contact-based definition, tied to a defined lookback, is the single biggest lever you have to make a customer non-solicitation clause survive a challenge.
Vendor/supplier non-solicit, sample language:
“Employee shall not, for twelve (12) months post-termination, induce any vendor or supplier with a material ongoing relationship with the Company to terminate or alter that relationship to the Company’s detriment.”
This one is less common and usually only worth including when a business has genuinely proprietary supplier terms, exclusive pricing, or a hard-won distribution relationship. Most companies don’t need it. Sales-heavy and staffing businesses often do.
As for placement: standalone non-solicitation agreements make sense for senior executives, partners, or anyone with unusually broad access to client relationships. For most employees, the clause lives inside the employment agreement or the severance agreement, where it’s easier to tie the restriction to consideration you’re already giving (a signing bonus, severance pay, or equity).
Pro Tip: Draft your client definition around “customers the employee had material contact with,” not “all customers of the company.” That single word swap, contact-based instead of company-wide, is often the difference between a clause that survives and one a judge guts on sight.
How Do Courts Decide If a Non-Solicitation Clause Is Enforceable?
Enforceability comes down to reasonableness, and reasonableness gets measured on a few consistent factors across most states. Courts ask how long the restriction lasts, how far it reaches, what it actually covers, and whether the company has a legitimate business interest worth protecting in the first place.
Duration is the easiest one to get right. Standard forms commonly use 12-month restrictions, and that period tends to hold up because it gives a business enough time to transition client relationships without permanently sidelining a former employee’s career. Clauses that stretch to three or five years draw more skepticism, especially for lower-level roles where the “legitimate business interest” argument gets thin.
Geography matters more for non-competes than non-solicits, since a non-solicit theoretically travels with the client relationship rather than a physical territory. Still, some states expect a defined scope even here.
Role matters a lot. A junior account coordinator with no client-facing responsibility is a much harder sell for a non-solicit than the account executive who personally closed every deal on that book of business. Courts look at whether the restricted person actually had the kind of access or relationship that justifies protection.
Legitimate business interest is the underlying test tying it all together: trade secrets, confidential pricing, established client goodwill, or specialized training the company invested in. A clause that exists purely to punish someone for leaving, with no real interest behind it, is the fastest way to lose in court.
State variance is where this gets genuinely tricky:
Texas generally enforces reasonable non-solicitation clauses under its Covenants Not to Compete Act, provided there’s adequate consideration and reasonable scope.
Florida has a statute that actually presumes certain restrictions reasonable if they fall within specific time limits, making Florida comparatively employer-friendly.
California is famously hostile to restraints on trade generally, and while non-solicits fare slightly better than non-competes there, courts scrutinize them heavily, particularly for client solicitation.
When a clause is overbroad, many states apply what’s called the blue-pencil doctrine: a court narrows the restriction to something reasonable rather than voiding it outright. New York courts have historically supported partial enforcement in BDO Seidman v. Hirshberg, where the appellate court discussed narrowing an overbroad covenant rather than striking it entirely. Other states, including some interpretations under Texas law, take a harder line and will void the whole clause if it’s drafted too broadly, rather than fix it for you.
A drafting note worth repeating: courts increasingly reward employers who wrote the clause narrowly the first time. Blue-penciling is a fallback, not a strategy.
On top of state contract law, there’s now a federal labor-law layer to watch. NLRB memos and decisions have signaled that overbroad non-solicitation and non-compete provisions can violate the National Labor Relations Act when they chill employees’ Section 7 rights to discuss wages, organize, or act collectively, regardless of whether the clause is otherwise enforceable under state contract law.
How Do You Write a Non-Solicitation Clause That Actually Holds Up?
Drafting a durable non-solicitation clause isn’t about legal cleverness. It’s about resisting the urge to write it broadly “just in case.” Broad clauses feel safer to the person drafting them and are, ironically, the ones most likely to get thrown out.
Define clients by contact, not by company roster. Tie the restriction to customers the employee actually served, sold to, or received confidential information about, within a specific lookback period, like the last 12 to 24 months.
Limit what counts as “solicitation.” Actively pursuing a former client is solicitation. A former client calling the departed employee unprompted usually isn’t, and your clause should say so. Courts look favorably on carve-outs for passive inbound business the employee didn’t chase.
Match duration to the role, not a template. A senior sales executive with deep client relationships might reasonably justify 18 to 24 months. A junior analyst probably can’t justify more than six to twelve. Copy-pasting one duration across your whole workforce is how you end up defending a clause you didn’t need to write that broadly.
Confirm real consideration. In states requiring separate consideration for restrictive covenants signed after employment begins, a bonus, promotion, or severance payment tied specifically to the agreement makes the clause far more defensible than “continued employment” alone.
Spell out the practical mechanics. Include notice requirements if the employee later disputes the restriction, and state what remedy you’re actually seeking (injunction, damages, or both) so there’s no ambiguity if this ever lands in front of a judge.
Pro Tip: Keep contemporaneous records of which employees had contact with which clients, ideally straight out of your CRM. When a case comes down to “did this person really have a relationship with that customer,” documentation usually decides it, not eloquent legal argument.
What Happens When a Non-Solicitation Clause Is Breached?
When an employer believes a former employee is violating their non-solicitation clause, the first move is almost always a cease-and-desist letter, not a lawsuit. It’s cheaper, faster, and sometimes enough on its own, especially if the former employee’s new employer wants to avoid getting dragged into litigation.
If that doesn’t work, the realistic remedies are:
Preliminary injunction. A court order stopping the solicitation while the case proceeds. This is usually the point of the whole exercise, since damages alone rarely make an employer whole once clients have walked.
Compensatory damages. Lost profits tied directly to the solicited clients or the cost of replacing departed staff.
Liquidated damages. A pre-set dollar figure written into the original agreement, useful if it’s a reasonable estimate of actual harm and not a punitive number designed to scare people into compliance.
Courts are notably less patient with employers enforcing clauses that were clearly overbroad to begin with. If your clause tried to ban solicitation of “any customer the company has ever had,” don’t be surprised when a judge either narrows it dramatically or refuses to enforce it at all, and awards the former employee’s legal fees in the process, depending on the jurisdiction and the agreement’s own fee-shifting language.
For employees on the receiving end of an enforcement threat, the most common defenses are that the clause is overbroad, that there was no legitimate business interest to protect, that consideration was inadequate, or that the employer breached the underlying agreement first (a nonpayment issue often unravels the whole restrictive covenant). If a dispute escalates past a demand letter, both sides typically bring in litigation counsel quickly, since the injunction fight usually happens on a compressed timeline.
What Antitrust and Labor-Law Traps Should Employers Avoid?
Here’s the part that catches a lot of business owners off guard: your non-solicitation clause with your own employee is a completely different legal animal from an agreement between your company and a competitor not to poach each other’s staff. The first is a normal, generally enforceable contract term. The second can be a criminal antitrust violation.
The Department of Justice and Federal Trade Commission treat naked no-poach agreements between competing employers, meaning agreements where two companies simply agree not to solicit or hire each other’s employees, as per se illegal under antitrust law. That means no balancing test, no “but we had a good reason.” The agreement itself is the violation, and it can trigger both criminal prosecution and civil liability. Notably, the agencies have made clear that even an informal understanding or a verbal invitation to collude, without a signed contract, can create exposure.
This is a real risk in industries where companies partner constantly: healthcare systems that share referral networks, tech companies with overlapping vendor relationships, franchise systems, or professional services firms that co-bid on projects. If your general counsel or ops lead ever gets asked by a “friendly competitor” to agree on hiring practices, that conversation should end immediately, and probably get reported up the chain.
Separately, the NLRB has taken the position that non-solicitation and non-compete language written too broadly can violate the National Labor Relations Act by chilling employees’ Section 7 rights to discuss working conditions or organize. A Region 25 decision out of Indianapolis required a company to rescind unlawful non-compete and solicitation provisions after finding they interfered with protected employee activity.
Compliance steps worth taking now:
Never discuss hiring plans, wage ranges, or no-poach terms with a competitor, even informally.
Review existing non-solicitation language for anything that could be read as restricting employees from discussing pay or working conditions with each other.
Keep client and employee non-solicitation clauses narrowly scoped to your own workforce, never extended to cover “industry-wide” cooperation.
When Should You Use a Non-Solicitation Clause Instead of Something Else?
Not every legitimate business interest calls for a non-solicitation clause. Sometimes it’s the wrong tool entirely.
Protecting client relationships: a customer non-solicitation clause, tied to direct contact, is usually the right fit.
Protecting trade secrets or confidential formulas: an NDA does more work here than a non-solicit ever will, since the goal is stopping disclosure, not just stopping outreach.
Retaining a critical employee through a transition: garden leave, where a departing executive stays on payroll but off active duty for a period, sometimes accomplishes more than a contested non-solicit ever could.
Buying out a specific client relationship: in professional services, a negotiated client-transfer or buyout agreement can resolve the risk cleanly without litigation down the line.
Operating in California or another employee-mobility-friendly state: leaning harder on confidentiality protections and trade-secret law, rather than mobility restrictions likely to draw a court challenge, is usually the smarter play.
How Chief Legal Office Approaches Non-Solicitation Clauses for Growth Companies
Most growing companies don’t need a thicker contract. They need someone who’s actually built these clauses before, watched them get challenged, and knows which version survives contact with a real dispute.
At Chief Legal Office, that’s how we scope non-solicitation language for technology and growth-stage clients: role by role, not template by template. A clause for a VP of Sales who personally owns twenty enterprise accounts looks nothing like the one for a customer support rep with no direct client relationships, and treating them the same is how companies end up with unenforceable paper.
The operational side matters just as much as the drafting. We build onboarding checklists that flag which roles actually need a non-solicitation clause, maintain templates so agreements stay consistent across hires instead of drifting year to year, and put enforcement playbooks in place before there’s ever a dispute, not after someone’s already walked out the door with a client list.
That structure is the difference between a founder scrambling to figure out what their own contracts say when a key employee resigns, and a legal function that already knows the answer.
Non-Solicitation Clauses: What the Conventional Advice Gets Wrong
Most advice on non-solicitation clauses treats them like a drafting problem. Get the duration right, get the geography right, and you’re covered. That’s incomplete, and it’s the part I’d push back on hardest.
The real risk for growing companies isn’t a badly worded clause getting struck down in court. It’s the two blind spots nobody drafts around: NLRB exposure on language that’s been standard for a decade, and antitrust risk that has nothing to do with your employee agreements at all and everything to do with a casual conversation between two founders at a conference.
If I had to prioritize one thing, it’s this: stop treating your non-solicitation clause as a one-time template exercise. Review it against how your roles have actually changed, because the clause you wrote for a five-person startup rarely fits the fifty-person company you are now. A clause that was reasonable for a junior hire in year one can be wildly overbroad for the senior role that same person grew into by year three.
The companies that get this right aren’t the ones with the most aggressive contracts. They’re the ones who revisit the language as the business changes.

FAQ
How Enforceable Are Non-Solicitation Clauses?
Non-solicitation clauses are generally enforceable across most U.S. states when they’re narrowly tailored to a legitimate business interest, reasonable in duration, and tied to actual client or employee contact. Enforcement varies significantly by state, and clauses drafted too broadly risk being narrowed or struck entirely under reasonableness standards.
How Long Does a Non-Solicitation Clause Last?
Most non-solicitation clauses last 12 months, though the reasonable duration depends heavily on the employee’s role and access to client relationships. Senior roles with deep client ties sometimes justify 18 to 24 months, while junior roles rarely support anything beyond six to twelve.
What Happens If You Breach a Non-Solicitation Clause?
Breaching a non-solicitation clause typically results in a cease-and-desist letter first, followed by a lawsuit seeking an injunction, damages, or both if the solicitation continues. Courts are less willing to enforce clauses that were clearly overbroad to begin with, which is why narrow drafting matters as much as the breach itself.
How Can Someone Challenge or Get Around a Non-Solicitation Clause?
The most common challenges argue the clause is overbroad, that no legitimate business interest justified it, or that the employer failed to provide adequate consideration when the agreement was signed. Some employees also argue the clause violates their rights under the National Labor Relations Act if it restricts discussing wages or working conditions with coworkers.
Is a Non-Solicitation Clause the Same as a Non-Compete?
No. A non-solicitation clause restricts contacting specific clients or employees, while a non-compete restricts where someone can work entirely. Non-solicitation agreements are generally viewed as narrower and more likely to survive judicial scrutiny than non-compete agreements covering the same person.
