How to Stop a Breach of Fiduciary Duty in California Business Litigation

What Is a Fiduciary Duty Under California Law?

Fiduciaries must act loyally, with care, and in good faith when entrusted with power over a company or another’s financial interests. In California, these duties commonly arise for:

• Corporate directors (statutory duties and business judgment rule protections: Corp. Code § 309; interested-director transactions: Corp. Code § 310).
• Corporate officers (recognized as fiduciaries under California case law; business judgment rule standards apply to directors, not to shield self-dealing or bad faith).
• LLC managers and managing members (duties may be modified but generally not eliminated; implied covenant cannot be waived: Corp. Code § 17701.10).
• Partners (duties of loyalty and care to the partnership and one another: Corp. Code § 16404).
• Controlling shareholders in closely held corporations (duty not to use control to the detriment of minority shareholders: Jones v. H.F. Ahmanson & Co., 1 Cal. 3d 93 (1969)).

The duty of loyalty prohibits self-dealing and usurpation of corporate opportunities; the duty of care requires informed, prudent decision-making; and fiduciaries must act in good faith for the benefit of the entity and its owners.

Common Warning Signs of a Breach

• Self-dealing transactions without proper disclosure or approval (Corp. Code § 310).
• Diverting corporate opportunities to a competing venture.
• Misuse or misappropriation of company funds or trade secrets (injunctive relief under Civ. Code § 3426.2).
• Insider favoritism, side deals, or undisclosed conflicts of interest.
• Withholding material information from co-owners, directors, or members.
• Manipulating financials, cap tables, or distributions.
• Freeze-outs or oppressive conduct toward minority owners (see Corp. Code § 1800(b)(4) for close-corporation dissolution grounds).

Immediate Steps to Protect the Business

• Preserve evidence: secure emails, messaging apps, cloud drives, accounting files, device backups, and access logs. Issue a written litigation hold.
• Lock down access: audit and, if appropriate, restrict access credentials, administrator rights, and financial authority consistent with governance documents and applicable law.
• Review governance documents: bylaws, shareholder agreements, operating or partnership agreements, board resolutions, and conflict-of-interest policies.
• Conduct a targeted internal review: interview key personnel, trace transactions, and reconcile bank, credit card, and expense records.
• Engage independent advisors: consider a disinterested special committee or outside accountant to evaluate questioned transactions.
• Assess insurance: review D&O, E&O, and fiduciary liability policies and give timely notice of potential claims.

Fast Court Relief: TROs and Preliminary Injunctions

When ongoing harm is likely, California courts can issue temporary restraining orders (TROs) and preliminary injunctions to maintain the status quo. Courts typically weigh the likelihood of prevailing on the merits and the prospect of irreparable harm, balancing interim harms and public interest (CCP Title 7, ch. 3; IT Corp. v. County of Imperial, 35 Cal. 3d 63 (1983)).

Courts can tailor orders to stop asset transfers, prevent misuse of trade secrets, suspend conflicted transactions, or require compliance with disclosure and approval procedures.

Other Powerful Remedies

• Accounting and constructive trust: fiduciaries can be ordered to account and to hold ill-gotten gains in constructive trust (Teselle v. McLoughlin, 173 Cal. App. 4th 156 (2009); Civ. Code § 2223; § 2224).
• Disgorgement: recovery of ill-gotten gains may be available even if precise damages are hard to quantify (Meister v. Mensinger, 230 Cal. App. 4th 381 (2014)).
• Damages: compensatory damages for proven losses and, in appropriate cases of fraud, punitive damages (Civ. Code § 3294).
• Rescission or reformation: unwind or correct tainted transactions (Civ. Code § 1689).
• Removal or suspension: seek to remove a conflicted fiduciary pursuant to governing documents and applicable entity statutes; courts also have tools such as appointing a provisional director in appropriate corporate cases.
• Receiver or neutral manager: ask the court to appoint a receiver to preserve assets and oversee operations during litigation (CCP § 564).
• Corporate opportunity remedies: compel return of usurped opportunities or profits.

Elements of a Breach of Fiduciary Duty Claim in California

A plaintiff generally must prove: (1) the existence of a fiduciary duty, (2) breach, and (3) harm caused by the breach. Equitable remedies like disgorgement or constructive trust may be available even where monetary damages are difficult to quantify (Oasis West Realty, LLC v. Goldman, 51 Cal. 4th 811 (2011); Meister). The business judgment rule protects informed, good-faith director decisions, but it does not shield self-dealing or bad faith (Corp. Code § 309).

Who Owes What: Corporations, LLCs, and Partnerships

• Corporations: Directors owe duties of loyalty and care to the corporation and, in some contexts, to shareholders; interested-director transactions require disclosure and proper approval (§ 309; § 310; Jones).
• LLCs: Managers and managing members typically owe fiduciary duties; operating agreements can modify certain duties (within statutory limits), but cannot eliminate the duty of loyalty outright or the implied covenant of good faith and fair dealing (§ 17701.10).
• Partnerships: Partners owe duties of loyalty, care, and good faith, including accounting for benefits and refraining from adverse dealings (§ 16404).

Derivative vs. Direct Claims

Owners often must bring derivative claims on behalf of the entity for harm to the company, while direct claims address individualized harm (such as dilution or a freeze-out). Shareholder derivative actions require standing, a pre-suit demand or specific reasons demand would be futile, and a verified complaint (Corp. Code § 800; see demand standards in Bader v. Anderson, 179 Cal. App. 4th 775 (2009)). For LLCs, derivative procedures are set out in Corp. Code § 17709.02.

Evidence That Moves the Needle

• Board minutes, written consents, and conflict disclosures.
• Emails, chats, and texts showing knowledge, intent, or non-disclosure.
• Financials: bank statements, general ledger detail, wire logs, expense reports.
• Cap tables, option grants, valuation materials, and deal files.
• Policies and approvals: procurement, expense, related-party approvals.
• Forensic traces: metadata, access logs, version histories, IP access records.

Strategic Considerations

• Choose the right forum and claims: breach of fiduciary duty, aiding and abetting (see Casey v. U.S. Bank, 127 Cal. App. 4th 1138 (2005)), constructive fraud, unfair competition (Bus. & Prof. Code § 17200), and trade secret misappropriation (Civ. Code § 3426.2) often overlap.
• Remedies first: align pleadings and early motion practice with the urgent remedy needed—injunction, receivership, accounting, or asset freeze.
• Privilege and independence: consider special committees and separate counsel for conflicted decision-makers.
• Settlement leverage: early injunctions and accounting orders can clarify facts and preserve assets, helping drive resolution.

FAQ

What is the statute of limitations for breach of fiduciary duty in California?

It depends on the claim’s gravamen. Claims sounding in fraud are typically three years, others may be four years. Accrual and tolling can vary; get case-specific advice.

Can an operating agreement eliminate fiduciary duties in an LLC?

No. Certain duties can be modified within limits, but the duty of loyalty cannot be eliminated and the implied covenant of good faith and fair dealing cannot be waived (see Corp. Code § 17701.10).

Do I need to make a demand before suing derivatively?

Shareholders generally must make a pre-suit demand or plead specific reasons why demand would be futile, and file a verified complaint (Corp. Code § 800).

Will the business judgment rule block my claim?

It protects informed, good-faith director decisions, but does not shield self-dealing, bad faith, or uninformed decisions (Corp. Code § 309).
