Business Partner Competes with the Company

You built your business with trust. Then something feels off. A deal falls through, a client disappears, or a new “competitor” looks oddly familiar. If you suspect a partner is competing with a business you own together, you’re not alone.

This article explains what this situation means, when it crosses the line, and what you can do next.

When Does a Partner Become a Competitor?

Not every overlap creates a legal issue. In some industries, partners and competitors operate in the same space. This is sometimes called “coopetition,” in which cooperation and competition coexist. However, problems arise when a partner acts against the company’s interests.

Common warning signs include:

Using company resources—using shared information, staff, or tools to benefit a competing business;
Diverting opportunities—taking clients, deals, or leads that should belong to the company; and
Creating a competing venture—starting or supporting a direct competitor without disclosure.

These actions can turn a working relationship into a serious partner conflict.

What Are Common Breach of Fiduciary Duty and Unfair Competition Partner Issues?

In many cases, when a partner is competing with a business, disputes center on fiduciary duties. These duties require partners to act in the company’s best interest. Partners are not supposed to be acting for personal gain at the company’s expense.

A breach of fiduciary duty (partner competition) may occur when a partner:

Competes directly with the company while still involved in its operations,
Uses confidential information for personal benefit, or
Fails to disclose a competing interest that creates a conflict.

Some situations also involve broader unfair competition by a partner that affects the company’s market position.

Examples include:

Misusing trade secrets—sharing confidential strategies with a market rival or new venture;
Interfering with relationships—disrupting contracts with clients, vendors, or suppliers; and
Creating confusion—presenting a competing business in a way that misleads customers.

These actions can expose the partner to legal claims. The business may be able to seek remedies to protect its interests and recover losses.

How Do You Navigate Competitive Tension and Market Overlap?

Not every situation involves clear wrongdoing. Some partners operate in overlapping markets or serve similar customers, which can create:

Competitive tension—when partners operate in similar spaces;
Channel conflict—when a partner competes for the same customers; and
Market overlap—when business activities intersect without clear boundaries.

The key question is whether the conduct crosses into a breach of duty or agreement.

How Does Business Partner Misconduct Affect Your Company?

When a partner acts against the business, the impact can spread quickly. Common effects include:

Financial loss. Lost clients or diverted opportunities can reduce revenue and growth.
Operational disruption. Internal conflict can slow decisions and create uncertainty.
Reputational harm. Customers and partners may lose confidence in the company.

Business partner misconduct can significantly affect daily operations and long-term strategy.

What Should You Review First? Agreements and Obligations

Before taking action against suspected business partner misconduct, review the agreements that govern your relationship. These documents often define what partners can and cannot do.

Partnership agreements often outline how the partners make decisions, share responsibilities, and resolve conflicts. Massachusetts law also provides default rules governing partner rights and duties when agreements are unclear.

Important documents may include:

Partnership agreement—outlines duties and decision-making authority;
Operating agreement—defines ownership and management roles;
Non-compete agreement—limits a partner’s ability to compete; and
Non-disclosure agreement (NDA)—protects confidential information.

These agreements often determine whether a partner’s actions violate legal or contractual duties.

What Legal Options Are Available When a Partner Competes?

If you suspect a partner is competing with the business, you may have several options, including:

Negotiation—address the issue directly with the partner before it escalates;
Injunctive relief—seek a court order to stop harmful conduct;
Damages—pursue compensation for financial losses; and
Buyout or exit—separate the parties through a negotiated or forced buyout.

Massachusetts law may also allow courts to order the dissolution of a partnership when the partners cannot resolve their disputes.

When Should You Seek Legal Guidance?

You do not need to wait for a major loss to act. You may want to speak with an attorney if:

You suspect a partner is diverting opportunities,
You discover a competing venture connected to your partner, or
Disputes begin affecting operations or finances.

An attorney can review agreements, assess claims, and guide next steps.
