Shareholder Disputes Experience

Shareholder disputes often arise where commercial relationships have broken down and the interests of individual shareholders, directors and the company no longer align. Our shareholder dispute lawyers advise on disputes involving unfair prejudice, minority shareholder rights, breaches of shareholder agreements, director misconduct, deadlock, disputed exits and the misuse of company assets.

We focus on identifying the client’s commercial objective early, whether that is preserving control, securing an exit, protecting the value of a shareholding or resolving the dispute without prolonged litigation.

Our shareholder disputes team has established a strong reputation in successfully representing businesses, business owners and high-net worth individuals throughout the UK, Europe and the Middle East.

Shareholder Dispute Services

We advise shareholders, directors and companies on unfair prejudice petitions, derivative claims, breaches of shareholder agreements, deadlock, director misconduct, disputed exits and urgent applications.

We are proud to be recognised by the leading directory Chambers & Partners for our work on shareholder disputes.

Unfair Prejudice Petitions

A shareholder can bring a petition under section 994 of the Companies Act 2006 where the company’s affairs have been conducted in a way that unfairly prejudices their interests. Common examples include exclusion from management, withholding dividends, excessive remuneration, dilution and diversion of business opportunities.

Minority Shareholder Disputes

We advise minority shareholders on disputes involving voting rights, access to information, dilution, board representation and exclusion from decision-making. These issues often overlap with unfair prejudice claims and quasi-partnership disputes.

Breach of Shareholder Agreements

We advise on breaches of shareholder agreements, including reserved matters, voting rights, funding obligations, share transfers, restrictive covenants, deadlock provisions and exit mechanisms. We work closely with our commercial law team where the dispute also involves wider contractual arrangements.

Shareholder Deadlock

Deadlock commonly arises where shareholders with equal voting power cannot agree on key decisions. Our shareholder dispute solicitors advise on contractual deadlock mechanisms, negotiated buy-outs and, where necessary, court proceedings or arbitration where the relevant agreement provides for it.

Derivative Claims

A derivative claim allows a shareholder to pursue proceedings on behalf of the company in relation to director wrongdoing, including breach of duty, negligence, default and misuse of company property.

Director and Shareholder Disputes

We advise on disputes involving conflicts of interest, diversion of business opportunities, misuse of company funds and alleged breaches of directors’ duties.

Shareholder Exits and Valuation

We advise on negotiated exits, share buy-outs, compulsory and voluntary transfers, leaver provisions and disputes over the value of a shareholding. Where an exit involves a wider restructuring, investment or transfer of ownership, our corporate team can also advise on the underlying transaction.

Just and Equitable Winding Up

Under section 122(1)(g) of the Insolvency Act 1986, the court can wind down down a company where it is just and equitable to do so, including in cases of serious deadlock or breakdown of a quasi-partnership.

Injunctions and Urgent Relief

Urgent relief may be required to prevent share transfers, asset dissipation, misuse of confidential information or significant corporate action while the underlying dispute is being resolved. These matters often form part of wider commercial litigation and dispute resolution proceedings.
