What the agreement actually says
Partnership and shareholder disputes usually turn on documents nobody has read closely since they were signed: a partnership agreement, articles of association, or a shareholders agreement. These set out what happens on disagreement, from voting rights and drag-along or tag-along clauses to how a partner or director can be removed. Before anything else, the starting point is establishing what was actually agreed, not what anyone remembers agreeing.
Unfair prejudice and minority protection
A minority shareholder who is being frozen out, excluded from decisions, or treated unfairly compared to other shareholders may have a claim for unfair prejudice under the Companies Act 2006. Remedies can include an order that the majority buy out the minority shareholding, often at a valuation set by the court rather than agreed informally.
Where a business has two equal partners or shareholders who can no longer agree, ordinary dispute remedies may not fit. In genuine deadlock, the practical question is often not who is right, but how the business gets unwound or one side gets bought out without destroying its value in the process.
Fiduciary duties
Partners and directors owe duties to act in good faith and in the interests of the business, not to profit personally at its expense, and to avoid conflicts of interest. Where those duties have been breached, whether through diverting business, misusing confidential information, or simple self-dealing, that breach can be a claim in its own right, separate from the wider dispute.
Getting to a resolution
Most of these disputes are better resolved than litigated to the end, since a business that survives a legal win but not the process is not much of a win. Mediation, a negotiated exit, or a share purchase agreement often achieves more than a judgment, though the credible threat of court proceedings is usually what gets the other side to negotiate seriously in the first place.
