Involuntary Dissolution of a California Corporation (Corporations Code 1800)

Last updated: November 2026

Involuntary dissolution is a lawsuit asking the superior court to wind up a California corporation over the objection of some of its owners. Corporations Code section 1800 says who may file and lists six grounds, including abandonment, director or shareholder deadlock, and persistent fraud, mismanagement, or unfairness toward shareholders. (Corp. Code, § 1800, subds. (a), (b).) In most cases the suit ends not in liquidation but in a buyout of the petitioning shareholder at fair value. (Corp. Code, § 2000, subd. (a).) Kolmogorov Law, P.C. brings and defends these actions in Orange County, Los Angeles, and across California.

Who can file for involuntary dissolution

The statute limits standing. A verified complaint may be filed by one-half or more of the directors in office. It may be filed by shareholders holding at least one-third of the outstanding shares, the outstanding common shares, or the equity of the corporation. In computing that one-third, shares owned by people who personally participated in the fraud, mismanagement, or unfairness alleged under the fourth ground are excluded. (Corp. Code, § 1800, subd. (a)(1), (2).)

Any shareholder of a statutory close corporation may file regardless of percentage. Any shareholder may file when the corporate term has expired. And the articles may authorize other persons to file. (Corp. Code, § 1800, subd. (a)(2)-(4).)

The six grounds

The grounds are set out in subdivision (b). (Corp. Code, § 1800, subd. (b)(1)-(6).)

First, the corporation has abandoned its business for more than one year.

Second, an even number of directors is equally divided and cannot agree on management, so the business cannot be conducted to advantage or is in danger of impairment. The shareholders must also be so divided that they cannot elect an odd-numbered board.

Third, internal dissension has left two or more shareholder factions so deadlocked that the business cannot be conducted with advantage to the shareholders. The same ground covers failure at two consecutive annual meetings to elect successors to directors whose terms have expired.

Fourth, those in control have been guilty of, or have knowingly countenanced, persistent and pervasive fraud, mismanagement, or abuse of authority, or persistent unfairness toward any shareholders. Misapplication or waste of corporate property by directors or officers also qualifies.

Fifth, in a corporation with 35 or fewer shareholders, liquidation is reasonably necessary to protect the rights or interests of the complaining shareholders.

Sixth, the period for which the corporation was formed has ended without extension.

The second and third grounds are the deadlock grounds, covered in more detail on our 50/50 deadlock page. The fourth and fifth are the minority-protection grounds behind most petitions in closely held companies. Our page on minority shareholder rights explains the conduct that qualifies.

Two ways it comes up

Two siblings inherit equal shares and seats on a two-person board. They disagree about whether to sell the company's building. Neither can outvote the other, the shareholders cannot elect a third director, and the lease on which the business depends is about to expire. That is the second ground.

A founder holds 60 percent, pays himself and his spouse salaries that consume the profit, and has stopped holding meetings or sending financial statements to the 40 percent holder. That is the fourth ground.

What the court can do

After hearing, the court may decree a winding up and dissolution if cause is shown. It may also, with or without dissolution, make orders and decrees and issue injunctions as justice and equity require. (Corp. Code, § 1804.) That gives the court room to order an accounting or restrain a transaction without ending the business.

The buyout that usually ends the case

The corporation, or if it declines, holders of 50 percent or more of the voting power, may avoid dissolution by purchasing the petitioners' shares for cash at fair value. (Corp. Code, § 2000, subd. (a).) Fair value is determined on a liquidation basis as of the valuation date, taking into account the possibility of selling the business as a going concern. The valuation date is the date the action was filed unless the court sets another for good cause. (Corp. Code, § 2000, subd. (f).)

If the parties cannot agree on value, the purchasers post a bond for the petitioners' expenses and the court stays the dissolution, appoints three disinterested appraisers, and confirms their award. (Corp. Code, § 2000, subds. (b), (c).) The decree then provides in the alternative: pay within the stated time or the corporation is wound up. (Corp. Code, § 2000, subd. (c).) One detail worth knowing: if the ground is the fourth one, the purchasers cannot deduct damages for the petitioner's alleged breach of a shareholder agreement in bringing the suit. (Corp. Code, § 2000, subd. (a).) The appraisal process is covered on our buyout valuation page.

Defending a dissolution petition

Majority owners sued for dissolution have several lines of defense. Standing is the first: a petitioner below one-third who cannot invoke the exclusion rule or the close corporation provision has no case. The merits are the second: deadlock requires actual inability to act, and the fourth ground requires conduct that is persistent, not a single bad decision, which the business judgment rule usually protects. The election to purchase is the third, because it converts the case from a fight over misconduct into a fight over price.

Where these cases are heard

The verified complaint is filed in the superior court of the proper county, usually where the corporation has its principal office: the Central Justice Center in Santa Ana for Orange County corporations, the Stanley Mosk Courthouse in Los Angeles. (Corp. Code, § 1800, subd. (a).)

What to bring to the first meeting

The articles, bylaws, and any shareholder or buy-sell agreement. The stock ledger or cap table. Minutes of the last several board and shareholder meetings. Financial statements and tax returns for three years. Compensation paid to the controlling owners. A timeline of the conduct you rely on.

Frequently asked questions

What is involuntary dissolution of a corporation in California?

A court proceeding under Corporations Code section 1800 in which qualifying directors or shareholders ask the superior court to wind up the corporation on one of six statutory grounds. The court may dissolve the company, issue lesser orders, or oversee a buyout of the petitioning shareholders at fair value. (Corp. Code, §§ 1800, 1804, 2000.)

Who can file for involuntary dissolution under Corp Code 1800?

Half or more of the directors, or shareholders holding at least one-third of the shares, excluding shares of those who participated in the alleged misconduct. Also any shareholder of a close corporation, any shareholder when the corporate term has expired, and anyone the articles authorize. (Corp. Code, § 1800, subd. (a).)

Can a 20 percent shareholder dissolve a corporation?

Not on percentage alone. A 20 percent holder reaches the one-third threshold only if the shares of those who personally participated in the alleged fraud, mismanagement, or unfairness are excluded from the count, or if the company is a statutory close corporation. (Corp. Code, § 1800, subd. (a)(2).) Otherwise the holder's remedies are derivative and direct claims rather than dissolution.

Will the court actually dissolve the company?

Usually not. Most cases end with the majority electing to purchase the petitioner's shares at fair value under section 2000, which stays the dissolution. (Corp. Code, § 2000, subds. (a), (b).) Liquidation happens when nobody elects to buy or the purchasers fail to pay the appraised price.

How long does an involuntary dissolution case take?

A contested petition through a confirmed appraisal typically takes a year or more. Early agreement on a valuation method shortens it. Disputes over standing or the valuation date lengthen it.
