When shareholders fall out, the consequences can ripple through a company for years. A shareholder agreement is meant to keep everyone on the same page about how decisions get made, how shares can move, and what happens when things go wrong. But agreements only work if people follow them, and when someone doesn't, the fallout can be messy. This page walks through what a dispute typically looks like in a UK company, the kinds of breaches that crop up most often, the remedies available when a party steps out of line, and the practical steps you can take to sort things out before they end up in court. Whether you're a minority shareholder feeling squeezed out or a founder dealing with a director who won't play by the rules, understanding your position is the first step.

What this document is

A shareholder agreement is a private contract between the shareholders of a company, and sometimes the company itself is a party too. It sits alongside the company's articles of association and sets out how the shareholders have agreed to run things between themselves.

That can cover anything from how directors are appointed, to what votes need a supermajority, to what happens if a shareholder wants to sell up or leave the business. A dispute arises when one party believes another has failed to honour those terms.

Unlike the articles, which are public, the shareholder agreement is confidential and tends to contain the more sensitive commercial arrangements. Disputes usually come down to contract law, so the starting point is always the wording of the agreement itself. Courts in England and Wales will generally enforce what the parties agreed, provided the terms are clear and lawful.

Getting to grips with what your agreement actually says, not what you thought it said, is where most disputes begin.

How to use this document

  1. Read the agreement carefully. Before doing anything else, go back to the document itself. Identify the specific clauses you believe have been breached and check any definitions, notice requirements, or timeframes. Many disputes dissolve once people re-read what they actually signed, and the wording will shape every step that follows.
  2. Gather your evidence. Put together copies of relevant emails, board minutes, share transfer records, financial statements, and any correspondence that shows what happened. The stronger your paper trail, the stronger your position if the matter escalates. Keep everything organised by date and make sure nothing gets deleted or altered.
  3. Raise the issue formally. Most shareholder agreements include a process for flagging a dispute, sometimes requiring written notice to the other party or the board. Follow that process properly. A well-drafted letter setting out your concerns can often prompt a resolution without needing to go further, and it also demonstrates good faith if things do progress.
  4. Explore mediation or negotiation. Litigation between shareholders is expensive, slow, and often damages the business itself. Mediation lets both sides talk through the issues with a neutral third party and find a workable settlement. Many agreements actually require mediation before court proceedings can begin, so check what yours says.
  5. Consider formal legal action. If negotiation fails, remedies may include a claim for breach of contract, an unfair prejudice petition under section 994 of the Companies Act 2006, or in serious cases, a petition to wind the company up on just and equitable grounds. Each route has different thresholds, costs, and outcomes.

Common questions

Q What counts as a breach of a shareholder agreement?
A breach happens when one party fails to do something the agreement requires, or does something it forbids. Common examples include transferring shares without following the pre-emption process, voting on matters that needed unanimous consent, sharing confidential information with outsiders, or breaking a non-compete clause. Whether a particular act amounts to a breach depends on the precise wording of the clause and the facts of what happened.
Q Can I force another shareholder to sell their shares?
Only if the agreement itself gives you that right, usually through a drag-along, compulsory transfer, or bad leaver clause. Without such a provision, you cannot simply demand another shareholder exits. Some agreements trigger a forced sale when certain events occur, such as a serious breach or the shareholder leaving employment. The exact mechanism and price calculation will be set out in the document.
Q What is an unfair prejudice petition?
It's a claim brought under section 994 of the Companies Act 2006 by a shareholder who believes the company's affairs are being conducted in a way that unfairly harms their interests. It's commonly used by minority shareholders who feel excluded from management or from returns. If successful, the court has wide powers, including ordering the majority to buy the petitioner's shares at a fair value.
Q How long do I have to bring a claim?
For a standard breach of contract claim under a shareholder agreement, the usual limitation period is six years from the date of the breach. Deeds can attract a longer period. Unfair prejudice petitions don't have a strict statutory deadline but delay can weaken your case. Acting promptly is almost always better, both legally and practically, so don't sit on your concerns.
Q Do shareholder agreements override the articles of association?
The two documents sit alongside each other, but where they conflict, the answer depends on what's being decided and who the dispute is between. A shareholder agreement binds the parties who signed it as a matter of contract. The articles bind the company and all shareholders. Well-drafted agreements usually contain a clause dealing with how any inconsistency is to be resolved.
Q Can disputes be resolved without going to court?
Yes, and most are. Negotiation, mediation, and arbitration are all common routes. Many shareholder agreements include a tiered dispute resolution clause that requires the parties to attempt mediation or another form of alternative dispute resolution before issuing proceedings. Settling out of court is usually faster, cheaper, more private, and less damaging to the ongoing business relationship than fighting it out in front of a judge.
Q What happens if the agreement is silent on a particular issue?
If the shareholder agreement doesn't address a point, the default position falls back on the company's articles of association and general company law, particularly the Companies Act 2006. That's why gaps in shareholder agreements often cause disputes in the first place. Courts will not usually write in terms the parties didn't agree to, so silence typically favours whoever benefits from the statutory default.
