Think Your Business Partner Is Taking Clients? Start With the Right Steps.

When a business partner appears to be taking clients, the steps you take and the order in which you take them can shape how the situation unfolds. First, save the records you already have. Second, read the agreements that govern your business. Third, hold off on a confrontation until you know the facts.

A partner who moves customers to a rival company can face claims for breach of duty, breach of a non-solicitation clause, or misuse of trade secrets. This page explains the warning signs, the documents to gather, and the Florida rules that shape what happens next. KEW Legal is a Florida business law firm with offices in Coral Gables and Sunny Isles Beach.

What Does It Mean When a Business Partner Is Stealing Clients?

A partner steals clients when a co-owner diverts customers to herself or a rival company while still owing duties to your business.

Leaving a company and serving customers somewhere new is not always wrongful. The line depends on what the governing documents say, when the partner acted, and how the customers were approached.

Lawyers describe the same conduct in different ways, such as diversion of business, usurpation of a business opportunity, or breach of duty. The label matters less than the facts behind it.

This page is written for owners, members, and partners in Miami-Dade and Broward County who still share an ownership or contract relationship with the person involved.

What Are the Warning Signs That a Business Partner Is Stealing Clients?

The most common early signs are revenue drops from specific accounts and a partner who suddenly controls those accounts.

• Revenue falls from named customers while the partner’s contact with them rises.
• Customers ask about a new company, new contact details, or a new billing name.
• The partner resists giving access to the CRM, invoices, or account files.
• Client messages move to personal email or messaging apps.
• Quotes or proposals appear under a different company name.

No single sign proves wrongdoing. A pattern that repeats over several months is what usually prompts a formal review. Write down each sign with its date while the details are fresh.

Which Documents Should You Gather First?

Start with the agreement that governs ownership, then collect the records that show who had the clients and who contacted them.

• The operating agreement, partnership agreement, or shareholder agreement, including any non-compete, non-solicitation, or confidentiality clause.
• Employment or contractor agreements the partner signed.
• The client list, when it was created, and who could access it.
• Sales, invoice, and payment records by client for the relevant period.
• Emails, texts, and messages showing contact with clients or a rival.
• Public formation records for any new company tied to the partner, which you can check in the Sunbiz filing database.

Preserve what exists. Don’t delete messages, log into accounts you aren’t authorized to use, or change shared systems on your own. Those steps can create new problems and weaken your evidence.

How Does Florida Treat Non-Solicitation Clauses?

A non-solicitation clause is enforceable in Florida only if it meets the requirements of Fla. Stat. § 542.335.

The statute sets several tests:

• The clause must be in writing and signed by the person it binds.
• The party enforcing it must prove a legitimate business interest, such as substantial relationships with specific customers or customer goodwill tied to an ongoing business.
• The restraint must be reasonably necessary to protect that interest.
• A court can modify an overbroad restraint and grant only the relief reasonably necessary.
• For former employees, agents, or independent contractors, a restraint of 6 months or less is presumed reasonable. A restraint of more than 2 years is presumed unreasonable.

Overbroad language is a common point of challenge, so the exact wording matters as much as the signature.

When Does a Trade Secret Claim Protect a Client List?

A client list can be protected as a trade secret only if it has independent economic value and the owner made reasonable efforts to keep it secret. Under Fla. Stat. § 688.002, as used in ss. 688.001-688.009, “improper means” includes theft, bribery, misrepresentation, breach or inducement of a breach of a duty to maintain secrecy, or espionage through electronic or other means.

Under Fla. Stat. § 688.002, a trade secret is information that is not generally known and not readily ascertainable by proper means. Using it without consent can count as misappropriation when the person had a duty to keep it secret.

The facts that matter include password protection, confidentiality agreements, restricted access, and marked files. The same client list may be protected in one business and not in another.

Courts can enjoin actual or threatened misappropriation (§ 688.003). Damages can include actual loss and unjust enrichment (§ 688.004).

The claim generally must be brought within 3 years after the misappropriation is discovered or should have been discovered with reasonable diligence (§ 688.007). Write down the date you first learned of the diversion.

What Duties Do Partners and LLC Members Owe Each Other?

Partners and LLC members owe each other duties of loyalty and care, and competing with the business while still involved can breach them.

In a general partnership, a partner’s only fiduciary duties are loyalty and care (Fla. Stat. § 620.8404). The duty of loyalty includes refraining from competing with the partnership before dissolution. The duty of care is limited to avoiding grossly negligent or reckless conduct, intentional misconduct, or a knowing violation of law.

Under Fla. Stat. § 605.04091, the members of a member-managed LLC owe duties of loyalty and care to the company and its members, while in a manager-managed LLC those duties fall on the managers, and a member does not owe them solely by being a member. The operating agreement may modify these duties within the limits of Fla. Stat. § 605.0105. The entity type decides which rules apply, so confirm whether your business is a partnership or an LLC before you act.

Records matter too. In a member-managed LLC, a member can inspect and copy required records on reasonable notice (Fla. Stat. § 605.0410). A partner who leaves wrongfully can be liable for the damages that departure causes (Fla. Stat. § 620.8602).

What Does Outside General Counsel Do When a Partner Leaves With Clients?

Outside general counsel is the ongoing legal advisor a business keeps for its legal questions. It also helps set the order of steps when a partner departs with clients.

This role typically covers:

• Reviewing the governing agreements before any demand goes out.
• Organizing records so the facts can be tested and shared with the right people.
• Drafting cease-and-desist letters and demands for return of records and property.
• Advising on what to say to customers so messages don’t create new liability.
• Coordinating employment issues when the departing person is also an employee, such as final pay, access removal, and written notices.
• Deciding when a matter needs litigation counsel and how the business keeps control of the process.
