Shareholder Disputes in UK Companies: The Role of an Independent Valuation

Why most shareholder disputes end up as a valuation question

Shareholder disputes in UK private companies usually start with something else: a director who has stopped working in the business, dividends that were cut, a founder who wants out, a deadlock over strategy. But almost every one of them is resolved the same way. One party buys the other out, and the argument narrows to a single question: what are the shares worth?

That is why an independent valuation sits at the centre of most settlements. It turns an emotional disagreement into a figure that can be tested, negotiated and, if necessary, defended before an expert or a court.

The most common sources of conflict

• Deadlock between 50/50 shareholders. Neither side can pass an ordinary resolution, so the company drifts.
• A shareholder leaving the business. Resignation, dismissal, ill health or retirement triggers leaver provisions, and the parties disagree on whether the person is a good or bad leaver.
• Exclusion of a minority. Removal as a director, loss of salary, no dividends and no information.
• Disagreement over a sale or investment. One party wants to sell or bring in an investor, the other does not.
• Divorce or death of a shareholder. Shares pass, or are claimed, by someone who was never involved in running the company.
• Diverted value. Allegations that one party has paid themselves excessively or moved business elsewhere.

How the legal route shapes the valuation

The same shareholding can have very different values depending on the route by which it is being priced. Before any number is produced, the valuer needs to know which basis applies.

The difference between the bases is not marginal. On a 30% holding, a pro-rata fair value and a discounted market value can commonly be 30% to 50% apart. Our guide to fair value vs market value sets out how the wording of a clause decides which applies.

What an independent valuation actually does in a dispute

It replaces two partisan numbers with one reasoned figure

Each side usually arrives with a number that suits it: the departing shareholder anchors high on a recent offer or a headline multiple, the remaining shareholders anchor low on last year's profit. An independent valuation explains how the business is valued, which adjustments are made and why. That reasoning is what moves negotiations forward.

It normalises the accounts

Disputes often involve exactly the items that distort reported profit: excessive or withheld director remuneration, personal expenses run through the company, one-off legal costs, related-party transactions. A valuer restates normalised EBITDA so that the figure reflects the business, not the conflict.

It fixes the valuation date

The date matters. Should the shares be valued before the alleged prejudice, at the date of the petition, or at the date of trial? If the business has declined because of the dispute, the choice of date can be worth more than any other assumption. The valuation should state the date and, where it is contested, show values at the alternative dates.

It isolates the discounts

Where a minority discount or a marketability discount is in play, an independent report shows the undiscounted pro-rata value and each discount separately. The parties, or the court, can then see exactly what is being argued about.

Single joint expert, party expert or expert determination

There are three common ways to appoint a valuer in a dispute, and the role differs in each.

• Single joint expert. Both parties instruct one valuer and share the cost. Faster and cheaper, and often the best route to settlement.
• Party-appointed expert. Each side instructs its own valuer. Useful in contested litigation, but it creates two reports to reconcile.
• Expert determination. Many shareholders' agreements provide that an independent expert sets the price and that the decision is final and binding, save for manifest error. The expert acts as an expert, not an arbitrator, and the clause's wording defines the task.

Where a report is required for court proceedings, it must comply with CPR Part 35, including the expert's overriding duty to the court. Optival treats expert witness work as a bespoke engagement, scoped and priced separately.

Worked example

Two founders each hold 50% of a UK software consultancy. One wants to leave; the articles say a leaver's shares are offered to the other shareholder at "fair value as determined by an independent expert", with no reference to discounts.

Because the clause refers to fair value and says nothing about discounts, the expert would usually adopt the pro-rata figure of £1,700,000. Had the clause referred to market value, a discount for a 50% deadlocked holding could reasonably reduce the figure, perhaps to somewhere around £1.2m to £1.4m. The same shares, two very different outcomes, decided by one word in the articles.

These figures are illustrative assumptions, not benchmarks for any particular company.

How to reduce the cost and length of a dispute

1. Read the articles and the shareholders' agreement first. They often already set the basis, the expert and the timetable.

2. Agree the valuation basis and date before the number. Most of the disagreement disappears once these are fixed.

3. Consider a single joint expert. One reasoned figure is easier to settle around than two opposing reports.

4. Give the valuer full access. Management accounts, forecasts and contracts. Disputes over information slow everything down.

5. Separate the valuation from the grievance. Allegations of misconduct may affect the remedy, but the valuer's job is to value the shares on the stated basis.

Common mistakes

• Assuming a minority discount always applies, or never applies, without reading the clause.
• Valuing at the wrong date, after the dispute has damaged the business.
• Using unadjusted accounts that reflect the conflict rather than the business.
• Relying on a headline multiple from a press article.
• Overlooking the tax consequences of the settlement, which are assessed on market value.
