Knowing how to resolve a shareholder dispute early is essential where disagreements are affecting decision-making, business value, or relationships between shareholders and directors.
In private, family-run and owner-managed companies, disputes often arise from exclusion from company decisions, dividend or remuneration disagreements, deadlock, alleged misconduct, breaches of a shareholders’ agreement, or concerns about unfair treatment by majority shareholders.
While court proceedings may sometimes be required, many shareholder disputes can be resolved through early legal advice, a careful review of the articles of association and shareholders’ agreement, structured negotiation, mediation, or a commercially focused buyout or exit.
This guide explains the key steps required to resolve a shareholder dispute, the rights and remedies available to shareholders, and the practical issues to consider before taking formal legal action.
If you need advice tailored to your position, our shareholder dispute solicitors can assess the dispute, protect your leverage and help you pursue the most effective route to resolution.
What is a shareholder dispute and when do I need a solicitor?
A shareholder dispute arises when those who own shares in a company disagree on how the business should be run, how value is distributed, or how decisions are made. These disputes can range from breakdowns in communication to serious allegations of misconduct or unfair treatment.
You may need a solicitor when the dispute begins to affect your financial interests, your ability to participate in the business, or the overall stability of the company. Early legal advice is particularly important where there is a risk of exclusion, deadlock, or breach of duties, as taking the wrong step early on can significantly weaken your position.
What causes shareholder disputes in private companies?
Most shareholder disputes don’t begin as legal problems, they begin as relationship breakdowns, particularly in owner-managed companies, personal and commercial interests are closely intertwined.
Relationships and interests can be even more complex in family-run businesses, where family politics can often lead to disagreements.
Founders may have started the business aligned in vision, or shareholders may have joined sharing the same ambitions, but over time expectations change. Disagreements can arise about strategy, risk appetite, reinvestment versus dividends, remuneration, or how to respond to poor performance.
Deadlock is also common, particularly in 50/50 companies where neither party has control and key decisions require agreement.
We also frequently see disputes where majority shareholders exercise their voting power in a way that a minority considers unfair, or where there are alleged breaches of the articles of association or shareholders’ agreement.
Exit scenarios are another trigger; whether a shareholder wants to leave, the company wants to bring in new shareholders diluting the shares of existing shareholders, or there is disagreement over valuation.
Often, the underlying issue is that expectations were never clearly documented, or the governance of the company hasn’t kept pace with its growth.
What is the difference between a shareholder dispute and a director dispute?
A shareholder dispute concerns ownership rights and interests in the company, whereas a director dispute relates to the management and operation of the business.
In many owner-managed companies, individuals act as both shareholders and directors, meaning disputes frequently involve both roles. This can complicate matters, particularly where allegations relate to breaches of director duties while also affecting shareholder value.
Where the disagreement also involves alleged mismanagement or misuse of company powers, advice on directors’ duties and corporate governance may be essential alongside the shareholder dispute itself.
Your rights as a shareholder under UK law
Under UK law, shareholders benefit from a range of statutory and contractual rights designed to protect their interests.
These typically include the right to:
- Receive certain company information;
- Vote on key decisions; and
- Share in the company’s profits through dividends (where declared).
Additional protections may arise under the company’s articles of association and any shareholders’ agreement, which often set out specific rights relating to decision-making, share transfers, and dispute resolution.
Where those rights are infringed, shareholders may have legal remedies available, including claims for unfair prejudice or, in certain circumstances, derivative actions (i.e. a claim brought on behalf of the company itself).
Can minority shareholders be forced out or excluded?
Minority shareholders or shareholders with less than a 50% shareholding in the company, cannot simply be forced out without proper legal basis. However, in practice they may find themselves marginalised or excluded from decision-making.
Where exclusion becomes unfair or prejudicial, the law provides protection. Minority shareholders may bring a claim where the company’s affairs are conducted in a way that unfairly harms their interests, often resulting in a buyout of their shares at a fair value. When determining the value of the shares being bought out, a minority discount may be applied.
What are the options if you've been excluded from company decisions?
If you find yourself being excluded from company decisions, there are ways in which you can assert your legal rights more formally. Under the Companies Act 2006, shareholders have rights including the right to receive certain company information, including annual accounts, and in some cases the right to inspect company records.
You may also have additional rights that are set out within the company’s Articles of Association and/or Shareholders’ Agreement; this will not always be the case, but these documents should be reviewed as soon as possible to determine what your position is.
A formal written request referencing those rights can be effective and is often the first step when trying to reach a resolution, or as a preliminary step before bringing formal court proceedings.
Before court proceedings are commenced, it is often worth seeking to negotiate a settlement with the other shareholders.
Negotiations may take place through the exchange of correspondence, although it is often useful for mediation to take place, particularly where the relationship between the parties has broken down, as the involvement of an independent mediator can help shift the parties’ focus from who is in the wrong to reaching a constructive and commercially sensible resolution.
As your legal representative, we would be able to assist in arranging the mediation, carrying out the necessary preparation, and being present on the day to assist you in seeking to reach settlement.
Business Mediation can take place before court proceedings are commenced, or after a claim has been issued sometime before the trial takes place. The best time for engaging in mediation will depend on the facts of each individual case, however it is often the case that the earlier a mediation takes place and results in settlement, the more the parties can save on the legal costs that would otherwise be involved with dealing with the claim.
In practice, shareholder disputes frequently result in one party buying out the other at a fair value, whether by agreement or by court order, which would usually stipulate that the minority shareholder’s shares are bought. Consideration should also be given to making an early offer along these lines in order to reach an early resolution and to protect your position on costs should the matter reach trial.
In urgent cases, injunctions may be considered (e.g. to prevent a certain course of action being carried out), but those applications are complex and fact specific. If you think you require an injunction, please contact a member of the Dispute Resolution team as soon as possible, as an application for an injunction will often need to be made without delay.
If settlement is not possible, our commercial litigation solicitors can advise on the most effective way to protect your position and move the dispute forward.
Preventing disputes and preparing for next steps
How can a shareholder agreement help prevent disputes?
Review the articles of association and any shareholders’ agreement. Those documents may contain important protections or mechanisms for resolving disputes.
A well-drafted shareholders’ agreement can significantly reduce the risk of disputes arising. It can set clear expectations around decision-making, dividend policy, exit provisions, and what happens in the event of disagreement or deadlock.
Putting a clear shareholders’ agreement in place can reduce the risk of future disputes by dealing expressly with decision-making, exits and deadlock.
Can you stop another shareholder from selling their shares?
In many cases, yes - depending on the company’s governing documents. The articles of association or shareholders’ agreement may include restrictions on share transfers, such as pre-emption rights requiring shares to be offered to existing shareholders first, or provisions controlling who can become a new shareholder. Where such provisions exist, they can be used to prevent or control the sale of shares.
What evidence do I need?
It’s also sensible to ensure there is a written record of events to maintain clarity. If matters aren’t documented already, seek to document them yourself.
For example, if you find yourself not invited to a meeting, send an email to the other shareholders stating what the meeting was, when it took place and enquire as to why you weren’t invited on this occasion. In addition, relevant evidence may include board minutes, financial records, correspondence, and any documentation demonstrating how decisions have been made. The strength of your position will often depend on the quality and consistency of the evidence available.
Resolving a Shareholder Dispute
How to resolve a shareholder dispute without going to court
Where possible, an open and constructive dialogue should be attempted. Many disputes can still be resolved without going to court. Outline your concerns in writing and ask that they be addressed.
Mediation is also often a sensible next step in some circumstances.
Whilst it is a formal step, and often involves solicitors, it allows parties to explore a commercial resolution without immediately resorting to litigation. Arbitration may also be available where provided for in the shareholders’ agreement, offering a more formal but still private method of resolving disputes.
Can a shareholder dispute be settled privately or confidentially?
Realistically, most shareholder disputes resolve through some form of negotiated exit. That may involve one party buying the other’s shares, a sale to a third party, or restructuring governance so the business can continue on clear, agreed terms. If agreement cannot be reached, formal proceedings such as an unfair prejudice petition may be considered.
However, litigation is usually a means to achieve a commercial outcome rather than an end in itself. The focus is typically on protecting or realising the value of the shareholding whilst allowing the parties to maintain confidentiality and limit any reputational damage.
Can a dispute be resolved without damaging the business relationship?
Yes, particularly where the dispute is addressed early and approached constructively. Alternative dispute resolution methods such as mediation are specifically designed to preserve relationships, enabling parties to reach commercially workable solutions without the adversarial nature of court proceedings.
Costs, timing & funding
What to check before starting legal action against another shareholder
Before issuing proceedings, it’s important to step back and consider the commercial realities. Litigation can be costly and time-consuming. It can also destabilise the business: it impacts on other shareholders, directors, and sometimes staff generally.
Litigation can also depreciate the value of the business which, if you are considering selling your shares, is not beneficial. Shareholders should consider the value of their shareholding compared to the likely cost of proceedings, how litigation would be funded, tax implications of any exit, the wider reputational impact and the personal impact on them.
Often the most effective strategy combines legal pressure with a clear focus on achieving a commercially sensible resolution.
How long do shareholder disputes take to resolve?
The timeline varies significantly depending on complexity, the willingness of parties to engage, and the route taken. Disputes resolved through negotiation or mediation may conclude within weeks or months, whereas litigation - particularly unfair prejudice claims - can take considerably longer.
Who pays the legal costs in a shareholder dispute?
In litigation, the general rule is that the unsuccessful party is likely to be ordered to pay a proportion of the successful party’s legal costs, although this is subject to the court’s discretion. In negotiated settlements, costs are often agreed between the parties as part of the overall resolution.
How can you fund a shareholder dispute claim?
In appropriate cases, such as when you are the party likely to be bought out as part of an exit from the business, we are happy to consider acting on a no win no fee basis. That would mean you do not pay fees as the matter progresses, with an uplifted fee payable only if the matter is successful, reflecting the risk we assume in potentially not getting paid if the outcome is not successful.
In addition, funding options may include Before the Event (BTE) insurance, After the Event (ATE) insurance, and fixed-fee arrangements for early-stage advice. Each option carries different advantages and risks depending on whether you are an individual shareholder or acting on behalf of a business, and will be considered on a case-by-case basis.

Business impact
What happens if a dispute involves a family-run or owner-managed business?
Particularly in owner-managed companies, personal and commercial interests are often closely intertwined. Relationships and interests are often even more complex in family-run businesses. This often means disputes are not purely commercial - they can involve long-standing personal relationships, making resolution more sensitive and complex.
Can a dispute affect the value or sale of a business?
As set out above, litigation can depreciate the value of the business which, if you are considering selling your shares, is not beneficial. Disputes can create uncertainty for buyers, impact financial performance, and delay or derail transactions. Resolving issues promptly and strategically is therefore critical to preserving value.
What is a derivative action?
A derivative action is a claim brought by a shareholder on behalf of the company, typically against a director for breach of duty. It is usually pursued where the company itself has suffered loss but is unwilling or unable to take action - often because those in control are the alleged wrongdoers.
These claims are complex and subject to court permission, making early legal advice essential.
