Fiduciary Duty Claims

Breach of Fiduciary Duty Between Business Owners

Co-owners owe each other duties of loyalty and good faith. When an insider diverts money, assets, or opportunities, California law provides a powerful set of claims.

Partners, managing members, and controlling shareholders owe fiduciary duties of loyalty and care to the company and its other owners. When an insider self-deals, diverts funds or opportunities, or misuses control, the harmed owners can sue for breach of fiduciary duty — directly or derivatively — to recover damages, profits, and other relief.

Closely held businesses run on trust, and that trust has legal force. The owners who control a California partnership, LLC, or corporation generally owe fiduciary duties — the highest duties the law imposes — to the company and their co-owners. When an insider breaks those duties to enrich themselves, the loss can be enormous, and so can the remedy. Stone LLP has pursued and defended these claims for Southern California owners for more than 45 years.

Who owes fiduciary duties

  • Partners owe each other and the partnership duties of loyalty and care under California partnership law.
  • Managers and managing members of an LLC owe fiduciary duties to the LLC and its members.
  • Directors, officers, and controlling shareholders owe duties to the corporation and, in the closely held setting, can owe duties that protect minority shareholders.

What a breach looks like

  • Self-dealing and undisclosed related-party transactions on unfair terms.
  • Diverting company funds, customers, or assets to the insider or an affiliated entity.
  • Usurping a company opportunity for personal benefit.
  • Competing against the company in violation of the duty of loyalty.
  • Misusing control to pay excessive compensation or squeeze out other owners.
  • Concealing material information or company books from co-owners.

The remedies

A breach of fiduciary duty claim can reach further than an ordinary contract claim. Depending on the facts, available relief may include compensatory damages, disgorgement of the wrongdoer’s profits, an accounting, the imposition of a constructive trust over diverted assets, removal of a manager or director, and — where the conduct is sufficiently serious — punitive damages. These claims also frequently strengthen a parallel dissolution or buyout case by establishing the misconduct that supports it.

Direct vs. derivative claims

Whether a claim belongs to the owner directly or to the company (a derivative claim brought on its behalf) is a threshold question that affects who recovers and how the case proceeds. In closely held companies the line can be subtle, and pleading the claim correctly is essential. We analyze which claims are direct, which are derivative, and how to position them for the best recovery.

Pursuing or defending the claim

Breach-of-fiduciary-duty disputes are fact-intensive and document-driven, and they often determine the tenor of an entire business divorce. We represent owners pressing these claims to recover what was taken, and insiders defending against overreaching allegations. From Irvine and Century City, Stone LLP serves owners throughout Orange County, Los Angeles, San Diego, and the Inland Empire.

Frequently asked questions

Do business partners owe each other fiduciary duties in California?

Yes. Partners generally owe each other and the partnership duties of loyalty and care. Managing members of an LLC and directors, officers, and controlling shareholders of a corporation owe similar fiduciary duties.

What can I recover for breach of fiduciary duty?

Depending on the facts, remedies can include compensatory damages, disgorgement of the wrongdoer’s profits, an accounting, a constructive trust over diverted assets, removal of a manager or director, and in serious cases punitive damages.

What’s the difference between a direct and a derivative claim?

A direct claim belongs to the owner personally, while a derivative claim is brought on the company’s behalf to recover for harm to the company. Which applies affects who recovers and how the case is litigated, and the distinction can be subtle in closely held companies.

Can a fiduciary duty claim help my buyout or dissolution case?

Often yes. Proving self-dealing or diversion can support the grounds for involuntary dissolution and strengthen your leverage in a buyout, in addition to providing its own remedies.
