Can a Former Employee Legally Take Your Clients With Them?
Whether this is legal depends heavily on what agreements were in place, and how the client relationship actually developed.
By Simon Touma · Updated August 14, 2026
Is It Legal for a Former Employee to Take Clients to a New Job?
Quick answer: It depends on whether the former employee signed an enforceable non-solicitation or non-compete agreement, whether they used confidential information like client lists to do it, and how the client relationship actually developed. Without a valid restrictive covenant or misuse of confidential information, a former employee generally has more freedom to compete than business owners often expect.

The Default Rule Without Any Agreement in Place
Without an enforceable non-compete or non-solicitation agreement, Arizona generally allows fairly open competition, a former employee can typically start a competing business or join a competitor, and clients are generally free to choose to follow them, absent some other legal violation.
This surprises many business owners who assume client relationships automatically belong to the business, in reality, absent a valid agreement or misuse of protected information, the relationship can follow the individual who built it.

How a Non-Solicitation Agreement Changes This
If the former employee signed an enforceable non-solicitation agreement, actively reaching out to former clients to solicit their business would generally be a breach, though a client independently choosing to follow them, without any active solicitation, presents a much harder, more fact-specific question.
This is exactly why having employees who develop meaningful client relationships sign appropriately tailored non-solicitation agreements, reviewed under Arizona’s reasonableness standard, is one of the most practical protective steps a business can take.
Misuse of Confidential Client Information
Separate from any restrictive covenant, if a former employee took actual confidential information, a client list, pricing details, contract terms, and used it to solicit clients, this can potentially constitute trade secret misappropriation under the Arizona Uniform Trade Secrets Act (A.R.S. § 44-401 et seq.), regardless of whether a non-solicitation agreement existed.
This is a distinct legal theory from a restrictive covenant claim, it focuses on the misuse of genuinely confidential, proprietary information, not simply on competing or serving former clients using information the employee could have reasonably known or recalled independently.
What Qualifies as a Genuine Trade Secret
Not all client information automatically qualifies as a protected trade secret. Generally, the information needs to have independent economic value from not being publicly known, and the business needs to have taken reasonable steps to keep it confidential, restricted access, confidentiality agreements, and similar safeguards.
A client list that is publicly available, or that any employee could easily reconstruct from public sources or general industry knowledge, is much less likely to qualify for this protection than a carefully guarded, genuinely proprietary client database.
The Difference Between Personal Goodwill and Business Goodwill
Courts sometimes distinguish between goodwill that belongs to the business itself, its reputation, marketing, and systems, versus personal goodwill an individual employee built through their own personal relationships and reputation, which can be much harder to legally restrict from following that individual.
This distinction matters especially for client-facing roles, sales, consulting, professional services, where clients often feel they have a relationship with the specific individual, not just the company name on the invoice.
What Businesses Can Do to Protect Client Relationships Proactively
- Use appropriately tailored non-solicitation agreements for employees in client-facing roles.
- Genuinely protect client information as confidential, restricted access, marked confidential, not freely available internally.
- Build client relationships around the business itself, not solely around one individual employee, where practical.
- Document actual instances of solicitation promptly if a dispute arises, timing and specifics matter.
What to Do if You Suspect a Former Employee Is Improperly Soliciting Clients
Document what you’re observing, which clients have left, when, and any evidence connecting it to the former employee’s outreach, and have an attorney evaluate whether an enforceable agreement was breached, or whether confidential information was misused, before taking further action.
Acting quickly matters here, both to preserve evidence and, where a court order is genuinely warranted, to limit ongoing harm to existing client relationships while the matter is being resolved.

Can a client just choose to follow a former employee to a new company?
Generally yes, absent an enforceable non-solicitation agreement and absent misuse of confidential information, clients are generally free to choose who they work with.
Is it illegal for a former employee to use a client list they remembered, without taking any documents?
This is a much harder question, information genuinely retained in someone’s memory, versus information taken from actual company records or documents, are treated very differently under trade secret law.
Do I need a signed agreement to protect against this at all?
Not always, trade secret protection can exist independent of a signed agreement, but a well-drafted non-solicitation agreement provides much clearer, more direct protection.
What if the former employee never signed anything?
Your options are narrower, generally limited to trade secret misappropriation claims if genuinely confidential information was misused, this is a good reason to have appropriate agreements in place proactively.
Can I stop a former employee from working with any of my past clients at all?
Only if an enforceable non-compete or non-solicitation agreement specifically covers that conduct, without one, this level of restriction generally is not available.
How quickly should I act if I suspect improper client solicitation?
Promptly, both to preserve evidence and because some remedies, like injunctive relief, are more available the more quickly a genuine, ongoing harm is addressed.
Does it matter whether the employee was fired or left voluntarily?
It can factor into the broader picture, but the core legal questions, whether an enforceable agreement exists, and whether confidential information was misused, generally apply regardless of how the employment ended.
Key Takeaways
- Without an enforceable agreement, former employees generally have real freedom to compete for clients.
- A properly drafted non-solicitation agreement changes this analysis significantly.
- Misusing genuine confidential information can support a separate trade secret claim.
- Not all client information automatically qualifies as a protected trade secret.
- Proactive protection, tailored agreements and genuine confidentiality practices, is far more effective than trying to respond after the fact.
