What Are Director and Shareholder Disputes?
Why These Disputes Matter
A shareholder dispute occurs when one or more shareholders (owners) disagree among themselves about how the company should be run, how profits should be shared, or how to value and sell shares.
A director dispute involves disagreement or conflict in a company’s board — for example, a director being accused of breaching fiduciary or statutory duties, or being excluded from decision-making.
These internal conflicts are not simply “business disagreements.” They can impose heavy financial, reputational and operational costs: stalled decisions, loss of confidence, damaged relationships, or even forced sale or winding up of the company.
In smaller businesses — particularly family-run or owner-managed companies — roles often overlap so the fallout is more personal, and the risks greater. We know how challenging this can be, and we tackle disputes with tact, clarity and strength.
Who Can Be Involved
- Majority shareholders and minority shareholders
- Executive directors, non-executive directors, or shadow directors
- Shareholders who are also directors (dual roles)
- The company itself (on behalf of all shareholders)
- Investors, joint venture partners, or external funding parties
At Jonathan Lea Network we act for all sides — whether defending, prosecuting, mediating, or structuring exits.
Types and Common Causes of Director and Shareholder Disputes
Understanding how director and shareholder disputes arise can help you identify problems early and take steps to protect your position before matters escalate.
1. Mismanagement and Breach of Directors’ Duties
Directors owe statutory general duties to the company under the Companies Act 2006. These include duties to act within their powers, promote the success of the company, exercise reasonable care, skill and diligence, avoid conflicts of interest, not accept improper benefits and declare interests in proposed transactions.
Disputes can arise where a director is accused of:
- Using company funds or assets for personal or unauthorised purposes
- Diverting business opportunities away from the company
- Pursuing competing business interests without proper disclosure
- Entering related-party transactions where they have a personal interest
- Accepting benefits from third parties because of their position as a director, or because of something they do or do not do as a director.
- Acting outside the company’s constitution, or using directors’ powers for an improper purpose.
- Failing to exercise appropriate care and skill when managing the company
We advise both those bringing and defending allegations concerning breaches of directors’ duties and can help assess the evidence, potential remedies and commercial options available.
2. Financial Conflicts, Transparency and Dividend Disputes
Disagreements over company finances are a common source of shareholder disputes.
Problems can arise where shareholders believe that financial information is being withheld, company expenditure is insufficiently explained or profits are being distributed unfairly.
Common issues include:
- Company accounts or financial information being withheld or delayed
- Incomplete or unclear financial records
- Significant expenditure or loans being authorised without appropriate consultation
- Disputes over directors’ salaries, bonuses or other benefits
- Disputes over whether profits should be retained for the business or distributed as dividends, including allegations that dividend decisions are being used unfairly to disadvantage particular shareholders.
- Alleged unequal or unfair treatment of shareholders in relation to dividends, remuneration or other financial benefits, taking account of the company’s articles, share rights and any shareholders’ agreement.
Where directors are also shareholders, disputes can become particularly contentious if directors receive significant remuneration or benefits while other shareholders receive little or no return from their shareholdings. Whether that gives rise to a legal claim depends on the circumstances, the company’s constitution, any shareholders’ agreement and the directors’ duties.
3. Strategic Direction, Control and Exit Strategy
Not every shareholder dispute involves wrongdoing. Serious disputes can also arise because shareholders or directors fundamentally disagree about the future direction of the business.
This may include disagreements over:
- Growth versus consolidation
- Reinvestment versus dividend distributions
- New funding or investment
- A proposed business sale or acquisition
- Whether shareholders should sell or retain their interests
- The level of commercial risk the business should take
Without clear decision-making or exit provisions, these disagreements can become entrenched and prevent the company from moving forward.
4. Deadlock Situations
Where ownership or voting rights are evenly divided, particularly in a 50/50 company, disagreements can result in deadlock if there is no casting vote, agreed escalation process or other effective deadlock-resolution mechanism.
If neither side can approve decisions requiring board or shareholder approval, the company may be unable to proceed with matters such as raising investment, appointing or removing directors, approving certain major contracts or making other significant commercial decisions.
We can advise on contractual deadlock mechanisms, negotiated settlements, share buy-outs, mediation and, where necessary, court remedies.
5. Undervalued or Forced Sale of Shares
Disputes can arise where a shareholder is being asked or required to sell their shares under the articles, a shareholders’ agreement or another legal mechanism, or where they believe that the proposed price does not fairly reflect the value of their interest.
Issues may include disputes over valuation methodology, compulsory transfer provisions, leaver provisions, share transfer restrictions or attempts by majority shareholders to require or procure an exit under alleged drag-along, compulsory-transfer or other contractual or constitutional provisions.
We can advise on the interpretation of the relevant agreements, valuation evidence and the options available to challenge or negotiate the proposed terms.
6. Unfair Prejudice and Exclusion from Management
Minority shareholders can be particularly vulnerable where majority shareholders also control the board.
Potential issues include:
- Exclusion from management or board meetings
- Being denied access to important company information
- Decisions being made without consultation where consultation is required by the company’s articles, a shareholders’ agreement, board procedures or the circumstances of the relationship between the shareholders.
- Dilution of a minority shareholding
- Unequal treatment in relation to profits or dividends
- Removal from management while other shareholders remain involved
Depending on the circumstances, this conduct may support an unfair-prejudice petition under section 994 of the Companies Act 2006. A petition is not available merely because a shareholder disagrees with a decision: the company’s affairs must have been conducted, or a proposed act or omission must exist, in a manner that is unfairly prejudicial to the interests of members or a relevant class of members.
7. Breach of Shareholders’ Agreements and Articles of Association
Shareholders’ agreements and articles of association commonly contain important provisions governing how the company should operate and how major decisions should be made.
Disputes may concern:
- Share transfers and pre-emption rights
- Drag-along and tag-along provisions
- Appointment or removal of directors
- Voting thresholds and reserved matters
- Board composition and quorum
- Share issues and dilution
- Exit rights and compulsory transfer provisions
We can advise on how these provisions should be interpreted and enforced, and whether decisions taken by shareholders or directors are valid.
8. Conflicts of Interest and Competing Businesses
Directors can face particular difficulties where they have interests in another business operating in the same or a related sector.
A dispute may arise if a director is alleged to have:
- Diverted clients or commercial opportunities
- Used company information, contacts or resources for another venture
- Established or supported a competing business in circumstances that may breach directors’ duties, confidentiality obligations or enforceable contractual restrictions.
- Failed to disclose their involvement in another business
- Put their personal interests ahead of those of the company
These situations can involve directors’ duties as well as contractual obligations, including confidentiality provisions and restrictive covenants. The enforceability of a restrictive covenant will depend on its wording, scope, duration and the particular circumstances.
We Act for Both Shareholders and Directors
Director and shareholder disputes often involve competing versions of events and complex questions about corporate governance, contractual rights and statutory duties.
We advise both shareholders and directors, which gives us a practical understanding of how these disputes develop and how each side is likely to approach them. We do not, of course, act for opposing parties in the same dispute where their interests conflict.
Advice for Shareholders
We can help shareholders:
- Understand their rights under the Companies Act 2006, the company’s articles and any shareholders’ agreement
- Investigate suspected mismanagement, exclusion or misuse of company assets
- Assess potential unfair prejudice, derivative or contractual claims
- Seek access to financial and company information where there is a legal, contractual or procedural basis for doing so.
- Challenge potentially improper dilution or disputed share transactions where there may be a breach of the articles, shareholders’ agreement, directors’ duties or applicable company law.
- Negotiate an exit or share buy-out
- Consider urgent protective or court action where the company’s assets, their shareholding or their legal rights may be at risk.
For minority shareholders in particular, early advice can be important where the majority also controls the board and the company’s resources.
Advice for Directors
We also advise directors who are facing allegations or disputes with shareholders or fellow board members.
This can include:
- Reviewing conduct against statutory directors’ duties
- Responding to allegations of breach of duty or conflicts of interest
- Responding to unfair-prejudice petitions and derivative claims brought on behalf of the company, including allegations directed at their conduct.
- Advising on the appointment or removal of directors under the Companies Act 2006, the company’s articles, service contracts and any shareholders’ agreement.
- Advising on boardroom deadlock and negotiating or implementing available resolution mechanisms.
- Negotiating settlements or exits
- Improving governance arrangements once the immediate dispute has been resolved
The appropriate strategy will depend on your position in the company, the company’s constitutional documents and the commercial outcome you are seeking.
Legal Framework and Protections
There are a number of legal avenues available to shareholders and, in some cases, directors. These remedies vary in complexity, cost, and potential outcomes, so choosing the right approach is vital.
1. Unfair Prejudice Petition – Section 994 Companies Act 2006
This is the most common remedy for minority shareholders who feel they have been unfairly treated. To succeed, you must show that:
- The conduct of the company’s affairs has been unfairly prejudicial to your interests as a shareholder
- The behaviour complained of is ongoing or recent enough to justify court intervention
Common examples of unfair prejudice include:
- Exclusion from management or decision-making without justification
- Withholding financial information or access to company records
- Misappropriation of company funds by majority shareholders
- Unequal distribution of profits or dilution of minority shareholding
If successful, the court can order the majority to buy out your shares at a fair value, among other remedies.
2. Derivative Claims – Sections 260–263 Companies Act 2006
Derivative claims allow a shareholder to bring a legal action on behalf of the company against a director (or directors) who have breached their duties. These are typically used where the wrongdoing harms the company itself, such as:
- Authorising unlawful payments or transfers of assets
- Failing to disclose personal interest in company transactions
- Negligent management causing loss to the company
The court must grant permission for a derivative claim to proceed, which involves an initial hearing to assess the merits of the case. If granted, the court may order damages, injunctions, or require directors to account for profits made.
3. Injunctions and Emergency Relief
In urgent cases where immediate harm is threatened — for example, where assets are at risk of being transferred or key decisions are being made in breach of agreements — the court may grant an injunction to:
- Stop unlawful share transfers or appointments
- Prevent the dissipation of company assets
- Suspend certain decisions until a full hearing can take place
This type of relief can be critical in preserving your position and stopping the damage while a longer-term solution is sought.
4. Just and Equitable Winding Up – Section 122(1)(g) Insolvency Act 1986
This is a more drastic remedy that asks the court to wind up (close down) the company due to irreconcilable differences among its shareholders. It is only granted in exceptional circumstances, such as:
- Total breakdown of mutual trust and cooperation
- Deadlock between shareholders in a quasi-partnership company
- Failure of the company to fulfil its intended commercial purpose
While rare, this remedy can be a powerful fallback when other options have failed or are unavailable.
5. Negotiated Share Buy-Outs
Where relationships have broken down but formal litigation is undesirable, a negotiated exit can be a practical solution. This may involve:
- Valuing the shares of the departing shareholder
- Agreeing a buy-out mechanism and timeline
- Ensuring non-compete and confidentiality protections are included
We can assist in negotiating terms that are fair, binding and enforceable.
6. Claims Under Shareholders’ Agreements or Articles
Many shareholder disputes can be resolved by enforcing the contractual terms already in place. We help clients:
- Enforce or defend against pre-emption rights, drag-along or tag-along clauses
- Clarify provisions around board composition and quorum
- Challenge decisions made in breach of the agreed corporate governance framework
Contractual claims are often quicker and less confrontational than statutory remedies and can bring clarity to ambiguous situations.
How Director and Shareholder Disputes Can Be Resolved
There is no single solution to a director or shareholder dispute. The best approach will depend on the underlying legal issues, the relationship between the parties and whether the business can realistically continue with its existing ownership and management structure.
In many cases, the ultimate solution is for one shareholder to exit the business or for one party to buy the other’s shares. This may be agreed between the parties, although a court can also order a share purchase in appropriate circumstances, including following a well-founded unfair-prejudice petition.
We will usually explore proportionate non-court solutions first while ensuring that your legal position is protected.
Negotiation and Settlement
Direct negotiation can often provide a quick and commercially sensible route to resolution.
We can help formulate settlement proposals, negotiate share buy-outs, agree payment structures, address valuation differences and document the final settlement so that the parties have certainty going forward.
Mediation
Mediation involves an independent mediator helping the parties explore whether an agreed resolution can be reached.
It can be particularly effective in shareholder disputes because the parties retain greater control over the outcome and can agree commercial solutions that a court may not have power to impose or may not consider appropriate on the facts.
These may include:
- A staged share buy-out
- Changes to management responsibilities
- Revised governance arrangements
- Payment arrangements
- Share transfers
- Confidentiality obligations and, where appropriate, enforceable restrictive covenants.
Arbitration and Expert Determination
Some shareholders’ agreements contain provisions requiring particular disputes to be referred to arbitration or expert determination. Whether such a provision applies will depend on its wording, the nature of the dispute and any applicable pre-action or escalation requirements.
Expert determination can be particularly useful for specific technical issues such as share valuation.
We can advise on whether contractual dispute-resolution provisions apply and advise or represent you through the relevant process, subject to the terms of the agreement and the nature of the dispute.
When Litigation Is Necessary
If ADR fails or is not viable, litigation becomes inevitable. Our team is well-versed in the full court process.
When to Consider Litigation
- One side refuses to negotiate in good faith
- The dispute involves fundamental legal rights or serious breaches
- Urgent interim relief is required (e.g. injunctions or freezing orders)
- A public ruling or declaratory judgment is needed
- Deadlock is harming the company irreversibly
What to Expect in Court
- Pre-action protocol and formal correspondence
- Filing of claim in the appropriate court (often the Business & Property Courts, Companies Court)
- Disclosure of documents and evidence
- Witness statements, expert reports (valuation, accounting, governance)
- Oral hearings, submissions and judgment
- Possible appeals
Relief may include:
- Order that the majority purchase the complainant’s shares
- Rectification of the articles
- Winding up of the company (just and equitable)
- Injunctive relief
- Damages or compensation
- Derivative actions (on behalf of the company)
We prepare clients thoroughly for the risk, timeline and cost of litigation, and help with strategic decisions about whether to press forward or settle.

Why Do These Disputes Matter (and Why Resolve Fast)?
Unresolved director and shareholder disputes can quickly affect the wider business.
Potential consequences include:
- Decision-making paralysis
- Loss of customers, employees or key suppliers
- Reduced investor or lender confidence
- Significant legal and management costs
- Damage to commercial relationships
- Loss of business value
- Forced restructuring, sale or winding up
Obtaining advice early can help identify the key legal and commercial issues before positions become entrenched.
It may also make it easier to preserve business continuity, protect important rights before significant decisions are taken and explore a negotiated solution before substantial litigation costs are incurred.
Where urgent action is required, early advice is particularly important. For example, there may be circumstances where steps need to be taken quickly to prevent a disputed share transfer, protect company assets or preserve the existing position while the dispute is resolved.
How to Prevent Shareholder Disputes (or Mitigate Risk)
Prevention is always better than cure — here are best practices we help clients adopt:
- Open & Regular Communication: Encourage transparency among shareholders and directors. Share key financials, hold regular board and shareholder meetings, document decisions and align expectations. Trust is easier to uphold than to rebuild.
- Clear Governance Frameworks: Establish clear policies for decision-making, role definitions, escalation routes, conflict resolution, data access and accountability. A strong governance structure reduces ambiguity.
- Early Exit & Buy-out Clauses: Include trigger events (death, disability, dispute, insolvency) for exits or buy-outs and valuation formulas (e.g. fixed formula, expert determination) in your agreements. Plan early, and reduce surprises later.
- Dispute Resolution Mechanisms: Embed mediation or arbitration clauses into contracts and shareholder agreements. By agreeing in advance how conflicts will be resolved, parties are more likely to follow those paths.
- Regular Review of Agreements: Businesses evolve. Regularly review and update articles, shareholder agreements and corporate governance frameworks to account for growth, new investors or structural changes.
- Alignment on Vision from Day One: Ensure that founding shareholders share core values and vision. Differences in strategy, risk appetite or time horizon are frequent seeds of conflict — candid upfront discussions help avoid misalignment later.

Frequently Asked Questions FAQs
-
Can a minority shareholder force the sale of the company or compel a buy-out?
-
Under an unfair prejudice petition (Companies Act 2006, section 994), a court may order that the majority buy out the minority’s shares on fair terms. However, the court will only grant this if it is just and equitable and the claimant proves prejudice (for example, exclusion from decision-making). It’s not guaranteed.
-
When can a derivative action be brought, and who does it benefit?
-
A derivative claim allows a shareholder to bring proceedings on behalf of the company (not for personal loss) where directors have harmed the company (e.g. misusing assets). Strict procedural criteria apply, including court permission and showing you represent the company’s interests.
-
How much does a director/shareholder dispute typically cost?
-
Costs vary hugely based on complexity, number of parties, expert evidence needed, length of proceedings and whether the matter settles. A relatively simple mediation might cost several thousand pounds; a full High Court dispute may run to tens or even hundreds of thousands. We always aim to manage costs and propose budget phases.
-
Can I get interim relief while the dispute is ongoing?
-
Yes. In urgent circumstances, courts may grant injunctions or freezing orders to prevent share transfers, restrict actions, or compel document disclosure while the dispute is ongoing. That protects your position while the main matter is resolved.
-
How long do these disputes usually take to resolve?
-
Again, it depends. Some cases settle in weeks or months via mediation. More complex litigated actions may take 12–24 months or more, particularly if appeals or expert evidence are involved. A quick-fix is often unrealistic where multiple parties and valuations are contested.
-
Should I wait until things get worse before instructing a lawyer?
-
No. Early legal advice can help you take protective steps (document preservation, preliminary letters, injunctions) and often prevent escalation. Delay can mean lost rights or weaker positions.
-
Will courts force me to sell my shares?
-
Courts are cautious about forcing forced sales. They are more likely to order a buy-out by the majority (compensating you) than compel you to sell unless circumstances justify it.
-
What happens if a dispute is settled but then breaches the settlement?
-
Settlement agreements are legally binding contracts. If one party breaks it, the other may sue for breach, apply to enforce via court, or in extreme cases set aside the settlement if misrepresentation or undue influence is proven.
-
Can non-UK shareholders or directors be involved in these disputes?
-
Yes. If the company is UK-incorporated, UK law governs many aspects. International parties may complicate jurisdiction or enforcement, but a good adviser can help manage cross-border issues.
-
What role does insurance or third-party litigation funding play in these disputes?
-
Some professional indemnity or director liability insurance policies may cover legal costs in certain claims. Litigation funding (third party) may also be possible in high-value cases. However, they come with costs and risks. We can advise whether those options are available in your specific case.
