Once someone enters into a business partnership, certain responsibilities can become legal requirements. Failing to uphold contractual agreements, fiduciary duties, or other legal obligations could potentially lead to liability. If you are joining a business partnership or are involved in a dispute, you may be wondering, “What fiduciary duties do business partners owe in California?”

Understanding these obligations can help business partners protect their interests and avoid costly legal disputes.

Fiduciary Duties Under California Law

California is home to approximately 4.3 million small businesses that often rely on business partnerships built on trust and shared responsibilities. When that trust is violated, the financial consequences can be substantial. According to the Association of Certified Fraud Examiners, occupational fraud committed by business owners and executives resulted in a median loss of $500,000 in cases examined for its 2024 report.

Under California Corporations Code § 16404, business partners owe certain fiduciary duties to one another and the partnership. These legal obligations apply to partnerships in Point West, the R Street Corridor, Fulton Avenue business district, and other communities in California, and help protect the business and its owners from misconduct, conflicts of interest, and abuses of authority.

Common Examples of Breaches of Fiduciary Duty

Disagreements between business partners can escalate into serious legal disputes. In a 2024 survey of 100 law firms, approximately one-quarter reported seeking outside assistance to resolve conflicts between partners over the preceding five years.

Common examples of breaches of fiduciary duty among California business partners include:

• Misappropriating company funds
• Diverting business opportunities
• Competing with the partnership
• Concealing financial information
• Engaging in conflicts of interest
• Misusing partnership property

Acts that may violate the state’s fiduciary duty requirements may expose the responsible partner to legal consequences and potential civil liabilities.

Legal Consequences of Breaching Fiduciary Duties

When a business partner allegedly breaches their fiduciary duties, they can become personally liable and face potential damage to their reputation and the prospect of litigation. Partners who suffer financial harm due to another partner’s misconduct may have grounds to pursue compensation through a civil claim.

Legal remedies may include recouping financial losses, requiring a partner to return improperly obtained profits, or obtaining a court order to stop ongoing acts of misconduct. As the dispute plays out, partnership finances may be examined to determine whether company funds were misappropriated.

A serious dispute could threaten ongoing business operations. In certain circumstances, California courts have the authority to dissolve a partnership when a partner demonstrates that continuing the business is no longer reasonably practicable.

Other remedies could have significant implications for the viability of a business. Whether you are seeking relief or defending yourself against accusations, Asbill Law Group can provide unwavering advocacy focused on protecting your rights and interests.

When to Hire a Business Litigation Lawyer

When a partner allegedly breaches their fiduciary duty, accusations can quickly become costly legal disputes. If you fail to hire a business litigation lawyer, the outcome of a business litigation case could damage your reputation and the viability of your company. California’s business litigation laws are complex and require interpretation from an experienced California business litigation attorney with experience handling these matters.

A business litigation lawyer can:

• Review partnership agreements and other governing documents to identify contractual obligations and potential violations.
• Gather and preserve financial records, communications, and other evidence relevant to the dispute.
• Assess the strengths and weaknesses of allegations and develop a legal strategy tailored to your circumstances.
• Negotiate with opposing parties to pursue a resolution that protects your financial and business interests.

FAQs

What Duties Does a Fiduciary Owe?

The duties that a fiduciary owes depend on the nature of the business relationship and applicable California laws. Common obligations include the duty of loyalty, duty of care, and duty of good faith and fair dealing. These responsibilities generally require fiduciaries to avoid conflicts of interest and improperly benefiting at the business’s expense. Other violations could deal with reckless or intentional misconduct.

Do Members of an LLC Owe Fiduciary Duties?

Members of an LLC in California may owe fiduciary duties depending on the company’s management structure and their responsibilities. In member-managed LLCs, members generally owe duties of loyalty and care to the company and other members. In manager-managed LLCs, these duties generally apply to managers rather than members acting solely as owners. Operating agreements may modify certain duties within limits established by California law.

Are Partners in a Partnership Personally Liable?

Partners in a partnership can be personally liable for certain business debts and legal obligations. In California general partnerships, partners are generally jointly and severally liable for partnership obligations, although exceptions may apply. Partners who breach fiduciary duties may also face personal liability for resulting financial harm. Liability rules differ for limited partnerships and limited liability partnerships.

Do CEOs Owe Fiduciary Duties?

CEOs do owe fiduciary duties to the corporations they manage. In California, corporate executives generally have responsibilities involving loyalty, care, and acting in the corporation’s interests. These obligations can include avoiding conflicts of interest, protecting confidential business information, and making informed decisions. CEOs who misuse company resources, engage in self-dealing, or otherwise breach their obligations may face legal consequences.
