Partnership disputes involving financial misconduct are more common than most business owners expect. A 2023 report by the Association of Certified Fraud Examiners (ACFE) found that small businesses lose approximately 5% of annual revenue to fraud, with a median loss of $150,000 per incident. Partner-on-partner theft, whether outright embezzlement, unauthorized distributions, or hidden self-dealing, can threaten the entire enterprise.

If you suspect your business partner is misappropriating company funds in California, here is what you should do, in order.

1. Secure Evidence Before Confronting the Partner

Before you say anything to your partner or take any public action, quietly gather evidence. Once accused, a dishonest partner may destroy records, transfer assets, or resign and claim entitlement to distributions. Preservation is everything.

Documents to secure: Bank statements for all company accounts (at least the last 24 months); credit card statements; QuickBooks or accounting software data; vendor contracts and invoices (look for fictitious or inflated vendors); payroll records; tax returns (partnership K-1s); emails and text messages discussing finances; operating agreement or partnership agreement.

If you have access to the company's accounting system, download and back up the full data set. If the company uses a cloud-based platform (QuickBooks Online, Xero, FreshBooks), export the data immediately. Partners who are stealing often alter or delete records once they learn they are under scrutiny.

2. Consult a Business Litigation Attorney

Before taking legal action, speak with an attorney who handles partnership disputes and breach of fiduciary duty claims. An experienced attorney can evaluate the strength of your evidence, advise whether to pursue civil claims (lawsuits for money damages and equitable relief), criminal referrals (reporting to law enforcement for embezzlement or theft), or both simultaneously.

In California, business partners owe each other a fiduciary duty, which is one of the highest duties recognized in law. This includes the duty of loyalty (Corp. Code § 16404(b) for general partnerships, § 15904.08 for limited partnerships, § 17704.09 for LLCs) and the duty to account for partnership property and disclose material information.

3. Freeze Company Accounts and Restrict Access

If your operating agreement allows it, or if you can obtain a court order, take steps to prevent further losses. Depending on the structure of your business and the authority granted by your governing documents, you may be able to remove the partner from signatory authority on bank accounts (contact the bank with a board resolution or written partnership consent), change passwords and access credentials for accounting software and financial platforms, place a hold on company credit cards, and restrict the partner's access to company property and systems.

If the governing documents do not give you unilateral authority to do this, you may need to seek a Temporary Restraining Order (TRO) or Preliminary Injunction from the court (Cal. Code Civ. Proc. § 527).

4. Pursue Civil Claims

California law provides several causes of action against a partner who steals or misappropriates company assets:

Breach of Fiduciary Duty. The most direct claim. You must show that the partner owed a fiduciary duty, breached it, and that the breach caused damages. Remedies include compensatory damages, disgorgement of profits, and potentially punitive damages under Cal. Civ. Code § 3294 if the conduct was fraudulent, malicious, or oppressive.

Conversion. The wrongful exercise of control over another's property. If your partner took company funds and used them for personal purposes, this is conversion (Cal. Civ. Code § 3336).

Accounting. A cause of action for an accounting compels the partner to provide a detailed record of all partnership transactions and their handling of partnership assets (Corp. Code § 16405(b)).

Constructive Trust. An equitable remedy that allows the court to trace stolen funds into whatever form they now exist (e.g., real property, investments) and impose a trust for the benefit of the partnership.

Dissolution and Winding Up. In extreme cases, you may petition the court for judicial dissolution of the partnership under Corp. Code § 16801. This allows for a supervised winding up where a court-appointed receiver may take control of partnership assets.

5. Consider Criminal Referral

Misappropriation of partnership funds may constitute embezzlement under Cal. Penal Code § 503 (embezzlement) or grand theft under Cal. Penal Code § 487 (theft exceeding $950). You can file a police report with local law enforcement or contact the district attorney's office directly.

A criminal case does not replace the civil case—they serve different purposes. The criminal case may result in restitution orders, and it creates pressure on the partner that can facilitate civil settlement. However, criminal investigations are controlled by the prosecutor, not by you, and outcomes are not guaranteed.

6. Protect the Business Going Forward

After addressing the immediate crisis, take steps to prevent future misconduct. Update your operating or partnership agreement to include dual-signature requirements for disbursements above a certain threshold, mandatory monthly or quarterly financial reporting, clear provisions for accounting and audit rights, buyout and expulsion provisions, and dispute resolution procedures (mediation, then arbitration or litigation).

Consider engaging a forensic accountant to conduct a full audit of the company's finances. Forensic accountants can trace diverted funds, identify fictitious vendors, and quantify the total losses—all of which strengthens both your civil claims and any criminal referral.

Statute of Limitations

The statute of limitations for breach of fiduciary duty in California is generally 4 years (Cal. Code Civ. Proc. § 343). However, the clock may be tolled (delayed) under the discovery rule if the partner actively concealed the misconduct. Courts apply the “delayed discovery” doctrine, meaning the statute of limitations does not begin to run until the plaintiff discovers, or should have discovered, the wrongdoing (Cal. Code Civ. Proc. § 338(d)).

Frequently Asked Questions

Q: Can I sue my business partner without dissolving the business?

A: Yes. You can pursue claims for breach of fiduciary duty, conversion, and an accounting without dissolving the partnership. Dissolution is typically a last resort when the partners can no longer work together and the business cannot continue.

Q: What if my partner claims the money was a legitimate distribution or loan?

A: Your attorney will examine the operating agreement, partnership agreement, tax records, and prior distribution patterns to determine whether the withdrawal was authorized. Unauthorized distributions that were not equally available to all partners, or that violated the terms of the governing documents, are actionable regardless of what the partner claims.

Q: How much can I recover?

A: Damages may include the full amount misappropriated, lost profits attributable to the misconduct, the cost of forensic accounting and attorney fees (if authorized by the partnership agreement or statute), disgorgement of profits the partner earned from the stolen funds, and punitive damages if the conduct was fraudulent or malicious.
