Partnership dispute services for Orange County owners

The disputes come in a handful of forms, and most files contain more than one.

Breach of fiduciary duty. A partner owes the partnership and the other partners a duty of loyalty and a duty of care. The duty of loyalty includes accounting for any profit or benefit taken from partnership business or property, not dealing with the partnership on behalf of an adverse interest, and not competing with it before dissolution. (Corp. Code, § 16404, subds. (a), (b).) Members of a member-managed LLC owe the same two duties, and the LLC statute defines the duty of loyalty in nearly identical terms. (Corp. Code, § 17704.09, subds. (a), (b).) Our fiduciary duty guide explains what the duty requires in practice.

Accounting and distribution disputes. A partner may sue the partnership or another partner for legal or equitable relief, with or without an accounting, to enforce rights under the agreement or the statute. (Corp. Code, § 16405, subd. (b).)

Lockouts and records disputes. One owner changes the passwords, the bank signatories, and the locks. The other has a statutory right to inspect the books. Our locked-out member page covers the remedies.

Buyouts and exits. Negotiated or litigated separations where one owner buys the other out, under the agreement's buy-sell terms or, where there are none, under the statute. See our partnership buyouts page.

Dissolution. Where the business cannot continue, a court may order it dissolved and wound up.

Three Orange County partnership disputes

Two dentists own a Mission Viejo practice as equal partners under a short agreement drafted years ago. One begins scheduling the profitable procedures at a second office he opened alone, using the partnership's hygienists and patient list. The other partner has a loyalty claim, an accounting claim, and a decision to make about whether the practice survives the lawsuit.

Three members of an LLC own an Irvine restaurant. The managing member stops sending financial statements, pays himself a salary nobody approved, and tells the others that their capital is gone. The two minority members have a records demand, a fiduciary claim, and possibly a derivative claim on behalf of the company. Whether the claim is direct or derivative decides who recovers.

A Huntington Beach construction partnership has no written agreement at all. One partner wants out, the other wants to keep the name and the equipment, and neither can agree on what the business is worth. The partnership statute's default rules fill the gap.

Dissolution as the remedy of last resort

When the owners cannot work together and nobody will sell, dissolution may be the only exit. A court may dissolve an LLC on a member's petition on several statutory grounds. They include that it is not reasonably practicable to carry on the business under the operating agreement, that management is deadlocked or subject to internal dissension, and that those in control have engaged in persistent fraud or mismanagement. (Corp. Code, § 17707.03, subd. (b).) The other members may avoid dissolution by buying out the petitioner for cash at fair market value, fixed by court-appointed appraisers if the parties cannot agree, which is often the real purpose of the petition. (Corp. Code, § 17707.03, subd. (c).)

Dissolution is expensive and public. We treat it as a bargaining tool first and a remedy second. Our guide to dissolving an LLC covers the process.

Where Orange County partnership cases are heard

Partnership, LLC, and shareholder disputes are filed in Orange County Superior Court at the Central Justice Center, 700 Civic Center Drive West, Santa Ana. Cases with many parties or with derivative claims may be designated complex and assigned to the Civil Complex Center. Dissolution and accounting claims are equitable and are decided by the judge rather than a jury, which affects how the case is prepared.

Many partnership and operating agreements require arbitration, and some require mediation first. We read the agreement for those clauses before any filing.

How the firm works on a partnership dispute

One attorney handles the matter. I read the agreement and the financial records myself, and in most cases I bring in a forensic accountant early, because the accounting is usually where the case is won or lost.

Partnership disputes are personal, and the owners often want vindication more than money. We try to steer toward the outcome that preserves value: a buyout, a negotiated separation, a receivership if the business is being looted.

What to bring to the first meeting

The partnership agreement, operating agreement, or bylaws and shareholder agreement, with every amendment. The last three years of tax returns and financial statements. Bank statements if you have access to them. The capital contribution records. The emails and messages where the dispute surfaced. If you have been locked out, the date and the written demands you have made.

Frequently asked questions

Can I force my business partner to buy me out in California?

Sometimes. If the agreement has a buy-sell clause, it controls. If not, a partner who dissociates from a partnership is generally entitled to have the partnership purchase the interest, and an LLC member who petitions for dissolution may be bought out by the other members at an appraised value. The path depends on the entity type and the agreement.

My partner locked me out of the business. What are my rights?

You have a right to inspect the books and records, a right to your share of distributions, and a right to sue for an accounting and for breach of fiduciary duty. In an emergency, a court can appoint a receiver or issue an injunction restoring access. Send a written demand for records first; the refusal becomes evidence.

Do I need a written partnership agreement to sue my partner?

No. A partnership can exist without a written agreement, and the statute supplies the default rules on duties, profits, and exit. The absence of a writing makes the case harder to prove, so bank records, tax returns, and the parties' course of conduct become the evidence.

How long does a partnership dispute take in Orange County?

A dispute that settles through a negotiated buyout can conclude in a few months. A litigated case with an accounting and a forensic expert usually runs a year to two years in Orange County Superior Court. Emergency relief, such as a receiver or an injunction, can be obtained much sooner.

Can a court dissolve our LLC if we cannot agree?

Yes. A member may petition for judicial dissolution on statutory grounds, including deadlock, internal dissension, and management that is not reasonably practicable under the operating agreement. (Corp. Code, § 17707.03, subd. (b).) The other members may avoid dissolution by buying out the petitioning member at fair market value. (Corp. Code, § 17707.03, subd. (c).) Most cases that start as dissolution petitions end as buyouts.
