Shareholder disputes and buy-outs

A shareholder dispute is a disagreement between the owners of a company, or between shareholders and directors, about how the business is run or how an owner is being treated. We act for majority and minority shareholders across South Wales and the South West, and in most cases the goal is the same: a fair exit for someone whose relationship with their fellow owners has broken down, usually achieved through a buy-out of their shares.

What is an unfair prejudice petition?

The main legal route for a shareholder who has been treated unfairly is an unfair prejudice petition under section 994 of the Companies Act 2006. It allows a shareholder to ask the court for relief where the company’s affairs are being conducted unfairly against them, for example exclusion from management, diversion of business or assets, or excessive director pay at the expense of dividends. The court’s powers are wide, but by far the most common order is that the other shareholders, or the company, buy the petitioner’s shares at a fair value.

Is there a time limit on a section 994 petition?

This changed recently. In early 2026 the Supreme Court held that the usual Limitation Act time limits do not apply to a section 994 petition. That does not mean there is no need to act, however, because the court can still refuse or reduce relief where a shareholder has delayed and that delay has caused unfairness. The practical message is unchanged: bring a dispute promptly, while the evidence is fresh and your position is strongest.

How are the shares valued?

Valuation is usually the real battleground, because it decides what the exiting shareholder is paid. Shares in a private company are not traded, so an independent expert, typically an accountant, assesses the value. A key question is whether a minority discount applies. A minority stake is often worth less per share because it carries no control, but in unfair prejudice cases, particularly in quasi-partnership companies, the court frequently orders a buy-out on a pro-rata basis with no minority discount. The valuation method and date can also make a substantial difference.

What if the company is deadlocked?

Where shareholders, often in a 50/50 company, cannot agree and there is no way to break the impasse, the company can be left unable to function. A well-drafted shareholders’ agreement may provide a deadlock mechanism, such as a casting vote or a buy-out procedure. Where there is none and the deadlock cannot be resolved, a shareholder can, as a last resort, petition to wind the company up on the just and equitable ground. Because that destroys the business, it is rarely the best outcome, and we look first for a commercial solution.

How are shareholder disputes resolved?

Most settle without a final hearing. Litigation is expensive, public and damaging to the business and the relationships involved, so the usual outcome is a negotiated buy-out. We frequently issue a petition to protect a client’s position and apply pressure while pursuing a settlement in parallel, and mediation is particularly effective here. Where the dispute also concerns someone’s position as a director, see our director and boardroom disputes page; for drafting a shareholders’ agreement to prevent disputes, see our business law team.

Common questions

Questions clients ask us about shareholder disputes

Whether a shareholder can be forced to sell their shares depends on the company's articles of association and any shareholders' agreement. Company law does not generally allow shareholders to be forced out, but the constitutional documents can provide for compulsory transfer in defined circumstances — known as 'good leaver' and 'bad leaver' provisions — for example, when a shareholder who is also an employee leaves the business, or on death or insolvency. In a shareholder dispute, the court can order a shareholder to sell their shares (or order their shares to be bought) as a remedy — most commonly in an unfair prejudice petition, where the usual outcome is a buy-out. Drag-along provisions in a shareholders' agreement can also require a minority to sell if the majority accept an offer for the whole company. Whether a forced sale is possible, and on what terms, depends on the specific documents and circumstances, and specialist advice is essential.

Yes — a shareholder can petition the court to wind up the company on the 'just and equitable' ground under Section 122(1)(g) of the Insolvency Act 1986. This is a drastic remedy that results in the company being dissolved and its assets distributed, and the court treats it as a last resort. It is most commonly used where: there is complete deadlock that cannot otherwise be resolved; the relationship of trust and confidence between the shareholders in a quasi-partnership company has irretrievably broken down; the company was formed for a purpose that has failed; or the shareholders' justifiable expectations have been frustrated. Because winding up destroys the business and is rarely the best commercial outcome, the court will often consider whether an alternative remedy — such as a buy-out under an unfair prejudice petition — would be more appropriate, and a petitioner who unreasonably seeks winding up rather than accepting a fair buy-out offer may be penalised. A just and equitable winding-up petition should only be pursued with careful legal advice.

Most shareholder disputes are resolved by negotiation and settlement rather than a final court hearing — and there are strong reasons for this. Litigation is expensive, time-consuming, and public, and it can be deeply damaging to the business and to the relationships between the people involved. The most common outcome is a negotiated buy-out, under which the departing shareholder's shares are purchased at an agreed value, allowing them to exit and the remaining shareholders to continue the business. Mediation is particularly effective in shareholder disputes because it allows confidential, commercially creative solutions and can preserve relationships where that matters. Court proceedings — such as an unfair prejudice petition — are often issued to protect a party's position and apply pressure, but settle before trial. The right strategy combines protecting the client's legal position with pursuing a commercial resolution. Taking early advice gives the best prospect of an efficient, cost-effective outcome.

Share valuation is often the central battleground in a shareholder dispute, because the amount payable on a buy-out depends on it. Shares in a private company are not traded on a market, so their value must be assessed — usually by an independent expert, typically an accountant with valuation expertise. Key issues include: the valuation method (such as earnings-based, asset-based, or a combination, depending on the nature of the business); the valuation date; and — significantly — whether a minority discount applies. A minority shareholding is often worth less per share than a controlling stake because it carries no control, but in unfair prejudice cases the court frequently orders a buy-out on a pro-rata basis without a minority discount, particularly in quasi-partnership companies, reflecting the unfairness of the situation. Valuation disputes can be complex and significantly affect the outcome, so expert valuation evidence and legal advice on the applicable principles are both important.

Many shareholder disputes can be prevented, or made far easier to resolve, through good planning at the outset. The single most effective measure is a well-drafted shareholders' agreement, put in place when the shareholders come together and relationships are good. It should address: how decisions are made and which require special consent; share transfer provisions and pre-emption rights; what happens when a shareholder leaves, dies, or becomes incapacitated; dividend policy; protections for minority shareholders; and a clear mechanism for resolving deadlock and disputes. Alongside the agreement, good corporate governance helps — keeping proper records, holding regular meetings, and ensuring decisions are documented and taken properly. Clarity about each shareholder's role, expectations, and exit options reduces the scope for the misunderstandings and frustrations that lead to disputes. Investing in a proper shareholders' agreement and sound governance at the start is far cheaper than litigating a dispute later.

Deadlock occurs when shareholders — often in a 50/50 company — cannot agree on a decision and there is no mechanism to break the impasse, leaving the company unable to function effectively. Deadlock is one of the most difficult shareholder situations. How it is resolved depends on whether there is a shareholders' agreement with a deadlock-breaking mechanism. Such mechanisms can include: a casting vote given to the chairman; referral to mediation or an independent expert; a buy-out procedure such as a 'shotgun' or 'Russian roulette' clause, under which one shareholder offers to buy the other out (or be bought out) at a stated price; or escalation to the parties' senior representatives. Where there is no agreed mechanism and the deadlock cannot be resolved, a shareholder may ultimately petition for the company to be wound up on just and equitable grounds — effectively dissolving the company. Because winding up is a drastic outcome, agreeing deadlock-breaking provisions in advance is far preferable.

A derivative claim is a claim brought by a shareholder on behalf of the company against a director (or sometimes a third party) for a wrong done to the company — such as a breach of the director's duties. Because the wrong is done to the company rather than the shareholder personally, the claim belongs to the company, and the shareholder brings it on the company's behalf, with any recovery going to the company. Derivative claims are governed by Sections 260 to 264 of the Companies Act 2006 and require the permission of the court to proceed — the court applies a two-stage test, considering whether there is a prima facie case and a range of factors including whether a person acting in the company's interests would pursue the claim. Derivative claims are less common than unfair prejudice petitions because of these hurdles and because the recovery benefits the company rather than the shareholder directly. They are appropriate where the wrong is to the company and the wrongdoing directors control it.

A shareholder dispute is a disagreement between the owners of a company, or between shareholders and the company's directors, about how the company is run or how shareholders are treated. They commonly arise from: disagreements about the strategic direction or management of the business; exclusion of a shareholder from management or decision-making; disputes over dividends or the distribution of profits; concerns that the company is being run for the benefit of some shareholders at the expense of others; breakdown of trust between business partners; disputes about the issue or transfer of shares; and disagreements when a shareholder wants to exit the business. Shareholder disputes are often particularly difficult because they combine legal, financial, and personal dimensions — frequently the shareholders are also directors, family members, or former friends. Early legal advice can help resolve a dispute before it damages the business or becomes intractable.

A shareholders' agreement is a private contract between the shareholders of a company governing their relationship and how the company will be run. It sits alongside the company's articles of association and can deal with matters that company law and the articles do not adequately address. A well-drafted shareholders' agreement helps prevent disputes by setting out clearly in advance: how decisions will be made and which decisions require unanimous or special consent; how shares can be transferred, including pre-emption rights giving existing shareholders first refusal; what happens if a shareholder wants to leave, dies, or becomes incapacitated; how disputes and deadlock will be resolved; dividend policy; and the protections afforded to minority shareholders. By agreeing these matters at the outset, when relationships are good, the shareholders create a framework that reduces the scope for disagreement and provides a clear mechanism for resolving issues if they arise. The absence of a shareholders' agreement is a common cause of disputes that could have been avoided.

An unfair prejudice petition under Section 994 of the Companies Act 2006 is the most common legal remedy in shareholder disputes. It allows a shareholder to petition the court on the ground that the company's affairs are being, or have been, conducted in a manner that is unfairly prejudicial to the interests of some or all shareholders, including the petitioner. Common examples of unfair prejudice include: exclusion of a shareholder from management in a company where they were entitled to participate; diversion of business or assets away from the company; excessive remuneration paid to directors at the expense of dividends; and improper allotment of shares to dilute a shareholder. The court has wide powers to grant relief — the most common order is that the majority (or the company) buy out the petitioner's shares at a fair value, allowing them to exit. Unfair prejudice petitions are the principal route for minority shareholders who have been treated unfairly.

Although they often overlap — because in many private companies the same people are both shareholders and directors — shareholder disputes and director disputes are legally distinct. A shareholder dispute concerns a person's rights and interests as an owner of the company: their shares, dividends, and treatment as a shareholder. A director dispute concerns a person's position and conduct as a manager of the company: their appointment, removal, powers, duties, and conduct in running the business. The legal remedies differ: shareholder remedies include unfair prejudice petitions and derivative claims; director issues involve directors' duties, removal under the Companies Act, and service contract or employment claims. Where the same individuals are both shareholders and directors, a dispute frequently involves both dimensions at once — for example, a person excluded from the board (a director issue) may bring an unfair prejudice petition (a shareholder remedy). Untangling the two and pursuing the right remedies requires careful legal analysis.

Minority shareholders — those holding less than a controlling interest — have important rights despite their lack of voting control. These include: the right to receive proper notice of and attend general meetings and to vote; the right to receive dividends if declared; the right to receive the company's accounts; statutory rights at certain ownership thresholds — for example, shareholders holding 5 percent can require a general meeting to be called, and 10 percent can demand a poll vote; protection against unfair prejudice under Section 994; the ability to bring a derivative claim in appropriate circumstances; and, in extreme cases, the right to petition for the company to be wound up on just and equitable grounds. The rights of minority shareholders are often enhanced by a shareholders' agreement, which can give them specific protections — such as veto rights over key decisions — that company law alone does not provide. Minority shareholders facing unfair treatment have meaningful legal options.
