📋 What is a Partnership Dispute?

A partnership dispute arises when partners disagree about the management, finances, or direction of their business, or when one partner breaches their duties to the partnership or other partners. Under California's Revised Uniform Partnership Act (RUPA), codified at Corporations Code Sections 16000-16962, partners owe each other fiduciary duties and have specific rights to information, accounting, and dissolution.

When to Use This Guide

Use this guide if your partner has:

🔒 Breach of Fiduciary Duty

Self-dealing, competing with the partnership, misappropriating opportunities, or failing to act in the partnership's best interest

💰 Improper Distributions

Taking unauthorized draws, unequal distributions, or depleting partnership assets without consent

📊 Denial of Accounting

Refusing to provide financial records, blocking access to books, or failing to account for partnership transactions

🚫 Management Disputes

Deadlock on major decisions, exclusion from management, or unilateral actions affecting partnership business

Types of Partnership Disputes Under California Law

🔴 Breach of Duty of Loyalty

Under Corp. Code Section 16404(b), each partner owes a duty of loyalty to the partnership and other partners. This includes the duty to account for profits derived from partnership business, refrain from dealing adversely to the partnership, and refrain from competing with the partnership.

Common violations: Diverting business opportunities, competing businesses, undisclosed self-dealing transactions, misappropriating partnership assets.

🟡 Breach of Duty of Care

Under Corp. Code Section 16404(c), partners must refrain from engaging in grossly negligent or reckless conduct, intentional misconduct, or knowing violations of law in conducting partnership business.

Note: California's standard is "grossly negligent" - simple negligence is generally not actionable. Partners are not liable for honest errors in business judgment.

🟢 Duty of Good Faith and Fair Dealing

Under Corp. Code Section 16404(d), partners must discharge their duties consistent with the obligation of good faith and fair dealing. This is an objective standard measured by what a reasonable person would expect under the circumstances.

Examples: Deceptive conduct, withholding material information, acting to undermine the partnership's purpose, bad faith refusal to consent to necessary actions.

🔵 Accounting and Information Disputes

Under Corp. Code Section 16403, each partner has the right to access partnership books and records, obtain information concerning partnership business, and demand a formal accounting. These rights cannot be unreasonably restricted.

Triggers for formal accounting: Upon dissolution, partner's wrongful exclusion, when partner profits at partnership's expense, or whenever circumstances render it just and reasonable.

👍 What You Can Demand in a Partnership Dispute

  • Formal accounting - Complete disclosure of all partnership transactions and finances
  • Return of misappropriated funds - Disgorgement of improperly taken assets or profits
  • Compensatory damages - Losses caused by breach of fiduciary duty
  • Dissolution and winding up - Termination of the partnership and distribution of assets
  • Buyout of interest - Purchase of your partnership interest at fair value
  • Injunctive relief - Court order preventing ongoing harm

⚠ Statute of Limitations

California has different time limits depending on the nature of your claim:

  • Breach of fiduciary duty: 4 years (CCP 343) - but may be tolled if breach was concealed
  • Fraud: 3 years from discovery (CCP 338(d))
  • Accounting: Generally 4 years, but may be filed at any time before dissolution is complete
  • Written partnership agreement: 4 years (CCP 337)

Act promptly to preserve your rights.

💰 Calculate Your Damages

In partnership disputes, damages can be substantial and may include both compensatory and equitable remedies.

Damage Type Description
Disgorgement of Profits Under Corp. Code 16404(b), a partner who profits from partnership business or use of partnership property must account for and return those profits. This includes secret profits, commissions, and undisclosed benefits.
Return of Misappropriated Assets Direct return of any partnership funds or property improperly taken or converted by the breaching partner.
Lost Profits Your share of partnership profits lost due to the breach, including diverted business opportunities and reduced partnership income.
Diminished Partnership Value Reduction in the value of your partnership interest caused by the breach (relevant for buyout or dissolution).
Buyout Price Under Corp. Code 16701, the fair value of your partnership interest calculated as if the partnership were wound up on the dissociation date.
Punitive Damages Available in cases of fraud, oppression, or malice. Unlike pure contract claims, fiduciary duty breaches may support punitive damages. See Civil Code 3294.

📊 Sample Damages Calculation

Example: Partner Self-Dealing and Misappropriation

Unauthorized distributions taken by partner $85,000
Diverted business opportunities (your share) $120,000
Undisclosed commissions/kickbacks $35,000
Your share of reduced partnership profits $45,000
Accounting and investigation costs $15,000
TOTAL COMPENSATORY DAMAGES $300,000

⚠ Punitive Damages May Apply

Unlike ordinary breach of contract claims, breaches of fiduciary duty may support punitive damages under California Civil Code 3294 if the conduct involves fraud, oppression, or malice. This can significantly increase the value of your claim and provides additional leverage in negotiations.

Breach of Fiduciary Duty
As a partner in [PARTNERSHIP NAME], you owe fiduciary duties to the partnership and to me as your co-partner. Under California Corporations Code Section 16404, these duties include the duty of loyalty, the duty of care, and the obligation to act in good faith and deal fairly. Your conduct, as detailed herein, constitutes a material breach of these fiduciary duties. Specifically, you have [DESCRIBE SPECIFIC BREACH: e.g., diverted partnership business opportunities to your personal company, taken unauthorized distributions, concealed material financial information, etc.]. This breach has caused substantial harm to both the partnership and to my interest therein.
Demand for Accounting
Pursuant to California Corporations Code Section 16403, I hereby demand a complete and formal accounting of all partnership affairs. This includes, but is not limited to: (1) all partnership income, expenses, and distributions from [START DATE] to present; (2) complete bank records for all partnership accounts; (3) all contracts, agreements, and business records; (4) documentation of all payments made to or for the benefit of any partner; and (5) a full accounting of partnership assets and liabilities. Under RUPA, I have the absolute right to this information, and your failure to provide a complete accounting within [30 DAYS] will be deemed a further breach of your fiduciary duties and will support judicial intervention.
Improper Distributions
Review of available partnership records reveals that you have taken distributions totaling $[AMOUNT] without proper authorization and in excess of your proportionate share. Under our partnership agreement and California Corporations Code Section 16401, distributions must be made equally among partners unless otherwise agreed. You have violated this requirement by taking: [LIST SPECIFIC UNAUTHORIZED DISTRIBUTIONS WITH DATES AND AMOUNTS]. I demand that you immediately return $[AMOUNT TO BE RETURNED] to the partnership account, representing the unauthorized excess distributions.
Self-Dealing Transactions
I have discovered that you have engaged in undisclosed self-dealing transactions that violate your duty of loyalty under Corporations Code Section 16404(b). Specifically, you have [DESCRIBE SELF-DEALING: e.g., caused the partnership to pay above-market rent to a property you personally own, directed partnership business to a company in which you have an undisclosed interest, received undisclosed commissions or kickbacks from partnership vendors, etc.]. These transactions were not disclosed to me and were not approved by the partnership. Under California law, you must account for and disgorge any profits derived from these transactions. I demand that you immediately provide a full disclosure of all such transactions and return all profits improperly obtained, which I estimate to total at least $[ESTIMATED AMOUNT].
Dissolution Notice
Given your material breach of fiduciary duties and the breakdown of the partnership relationship, I hereby provide notice of my intent to dissolve [PARTNERSHIP NAME] pursuant to California Corporations Code Section 16801. [IF AT-WILL PARTNERSHIP: As this is a partnership at will, this notice is effective immediately to dissolve the partnership.] [IF TERM PARTNERSHIP: I am dissociating from the partnership and demand a buyout of my partnership interest pursuant to Corporations Code Section 16701.] I demand that you cooperate in the orderly winding up of partnership affairs, including a full accounting, liquidation of partnership assets, payment of partnership debts, and distribution of remaining assets in accordance with our respective partnership interests. Any attempt to continue partnership business without my consent or to dispose of partnership assets outside the winding up process will be unlawful.

Re: Demand for Accounting, Return of Misappropriated Funds, and Notice of Breach of Fiduciary Duty - [PARTNERSHIP NAME]
Dear [PARTNER NAME]:

I am writing in my capacity as a partner in [PARTNERSHIP NAME] (the "Partnership"), a California general partnership formed on or about [FORMATION DATE]. I made an initial capital contribution of $[CAPITAL CONTRIBUTION] and hold a [PERCENTAGE]% interest in the Partnership. This letter constitutes a formal demand for accounting, return of misappropriated funds, and notice of your material breach of fiduciary duties owed to me and to the Partnership.

FACTUAL BACKGROUND

The Partnership was formed to engage in [BUSINESS PURPOSE]. Under our partnership agreement [dated DATE / or, if oral, as mutually agreed], profits and losses were to be shared [equally / in proportion to capital contributions / per specific percentages], and major business decisions required [mutual consent / majority vote / unanimous agreement].

I have recently discovered that you have engaged in conduct that constitutes a serious breach of your fiduciary duties as a partner. Specifically, you have:

1. [DESCRIBE FIRST BREACH - e.g., "Taken unauthorized distributions totaling approximately $85,000 from the Partnership account between January 2024 and June 2024, without my knowledge or consent and in excess of your proportionate share."]

2. [DESCRIBE SECOND BREACH - e.g., "Diverted at least three business opportunities that rightfully belonged to the Partnership to your separately-owned company, [COMPANY NAME], resulting in lost profits to the Partnership of approximately $120,000."]

3. [DESCRIBE THIRD BREACH - e.g., "Failed to disclose and account for commissions and referral fees totaling approximately $35,000 that you received from Partnership vendors."]

4. [DESCRIBE ADDITIONAL BREACHES AS APPLICABLE]

LEGAL BASIS

Under California's Revised Uniform Partnership Act, Corporations Code Sections 16000-16962, you owe fiduciary duties to both the Partnership and to me as your co-partner. Specifically:

Corporations Code Section 16404(b) requires you to account to the Partnership for any profit derived from Partnership business or use of Partnership property, and to refrain from dealing with the Partnership on behalf of parties having an adverse interest.

Corporations Code Section 16404(d) requires you to discharge your duties in good faith and deal fairly with the Partnership and your co-partners.

Your conduct, as described above, constitutes a material breach of these statutory duties. Under California law, partners stand in a fiduciary relationship requiring the highest good faith, candor, and fair dealing. See Jones v. Wells Fargo Bank (2003) 112 Cal.App.4th 1527.

DEMAND FOR ACCOUNTING

Pursuant to Corporations Code Section 16403, I hereby demand a complete and formal accounting of all Partnership affairs from [START DATE] to present. Within fifteen (15) days of this letter, you must provide:

DEMAND FOR PAYMENT

Based on the information currently available to me, I demand that you pay to the Partnership the sum of $[TOTAL AMOUNT], representing:

Unauthorized distributions: $[AMOUNT]
Diverted business profits (Partnership share): $[AMOUNT]
Undisclosed commissions/fees: $[AMOUNT]
[OTHER ITEMS AS APPLICABLE]: $[AMOUNT]
TOTAL: $[TOTAL]

This demand is based on limited information. Following a complete accounting, the amount owed may increase. I reserve all rights to seek additional damages.

DISSOLUTION / DISSOCIATION NOTICE

[INCLUDE IF SEEKING DISSOLUTION:] Given your material breach of fiduciary duties and the irreparable breakdown of our partnership relationship, I hereby provide notice of my intent to dissolve the Partnership pursuant to Corporations Code Section 16801. [For at-will partnerships: This notice is effective immediately.] [For term partnerships: I am dissociating from the Partnership pursuant to Section 16601 and demand a buyout of my partnership interest at fair value pursuant to Section 16701.]

DEADLINE AND CONSEQUENCES

You must respond to this demand in writing within thirty (30) days - by [DEADLINE DATE]. Your response must include the complete accounting demanded above and a proposal for returning the misappropriated funds.

If you fail to respond adequately by this deadline, I will have no choice but to pursue all available legal remedies, including but not limited to:

1. Filing a civil action for breach of fiduciary duty, fraud, and accounting;
2. Seeking preliminary injunctive relief to protect Partnership assets;
3. Petitioning for judicial dissolution under Corporations Code Section 16801(5);
4. Seeking compensatory damages, disgorgement of profits, and punitive damages;
5. Seeking an award of attorneys' fees and costs.

This letter is written to resolve this dispute without litigation. However, I am prepared to take all necessary legal action to protect my rights and the interests of the Partnership.

This letter is not intended to be, and shall not be construed as, a waiver of any rights or claims I may have. All rights are expressly reserved.

Very truly yours,

If They Don't Respond or Pay

  1. Consult a Business Litigation Attorney

    Partnership disputes are complex. Many attorneys offer free initial consultations. Look for experience in business litigation and partnership law specifically.

  2. File for Judicial Accounting

    You can petition the court for an order compelling your partner to provide a complete accounting under Corp. Code 16403. The court can appoint a receiver or accountant if necessary.

  3. Seek Preliminary Injunction

    If your partner is dissipating partnership assets or continuing harmful conduct, seek immediate injunctive relief to preserve the status quo.

  4. File Civil Lawsuit

    Claims may include breach of fiduciary duty, fraud, conversion, and accounting. California Superior Court has jurisdiction for unlimited civil cases over $25,000.

  5. Consider Mediation

    Many partnership agreements require mediation before litigation. Even without such a requirement, mediation can be cost-effective for resolving partnership disputes.

⚠ Protect Partnership Assets

If you believe your partner is dissipating or hiding partnership assets:

  • Document everything immediately with screenshots and copies
  • Consider freezing joint accounts (but be aware this may trigger counterclaims)
  • Seek emergency injunctive relief from the court
  • Preserve all electronic evidence - do not delete anything
