None of these scenarios are unusual. All of them can be devastating. And almost all of them can be managed — if you have a shareholder agreement in place before they happen.
This guide explains what a shareholder agreement is, what it does, and why it is the most important legal document your business is probably missing.
What Is a Shareholder Agreement?
A shareholder agreement is a private contract between the shareholders of a company that governs how the company is run, how decisions are made, and what happens to shares in various circumstances. Unlike a company’s Articles of Association (which are public and filed at Companies House), a shareholder agreement is confidential and offers far greater flexibility.
It sits alongside your Articles of Association and takes precedence over them in most circumstances where there is a conflict.
What Does It Actually Cover?
A well-drafted shareholder agreement typically covers the following:
Decision-making and voting rights. Which decisions require a simple majority? Which require unanimity? Many shareholder disputes arise because the parties never agreed in advance on who has the final word on major decisions — like taking on significant debt, entering a new market, or appointing a new director. A shareholder agreement sets this out clearly.
Dividend policy. When will profits be distributed? What proportion will be retained in the business? Disagreements about dividends are one of the most common sources of shareholder conflict, and they are entirely preventable.
Share transfer restrictions. Can a shareholder sell their stake to anyone they like? A shareholder agreement can include “right of first refusal” provisions — giving existing shareholders the chance to buy departing shareholders’ shares before they are offered to outsiders. This protects the business from ending up with unwanted co-owners.
Drag-along and tag-along rights. If a majority shareholder wants to sell the whole company, a drag-along right allows them to require minority shareholders to sell too — preventing a minority from blocking a deal. Tag-along rights protect minority shareholders by ensuring that if the majority sells, the minority can join the sale on the same terms.
Leaver provisions. What happens when a shareholder leaves — whether voluntarily, involuntarily, or because of death or incapacity? Good leaver / bad leaver clauses determine whether a departing shareholder gets market value for their shares or a reduced amount, depending on the circumstances of their departure.
Non-compete and non-solicitation clauses. Can a departing shareholder immediately set up a competing business? A shareholder agreement can include restrictions that protect the company from a departing founder taking clients or employees.
Deadlock resolution. What happens when shareholders are split 50/50 and cannot agree? Without a deadlock mechanism, a 50/50 company can become completely paralysed. A shareholder agreement can set out a process for resolving deadlock — whether that is mediation, a casting vote, or a buy-sell mechanism.
Why Not Just Rely on the Articles?
Most companies — especially those formed using Companies House’s model articles — have Articles of Association that are very basic. They deal with administrative matters but provide almost no protection for minority shareholders, no restrictions on share transfers, and no provisions for what happens when things go wrong.
A shareholder agreement fills those gaps. It is also private, which means your commercial arrangements and the terms on which you have agreed to work together are not available for competitors, clients or the public to read.
When Should You Put One in Place?
The honest answer is: before you need one. The ideal moment to negotiate and sign a shareholder agreement is at the very beginning of a business relationship — when everyone is aligned, relationships are positive, and there is no live dispute to poison the discussions.
Trying to agree a shareholder agreement when a dispute has already arisen, or when the relationship between founders has broken down, is significantly harder, more expensive, and less likely to produce a fair result.
If your company does not have a shareholder agreement — or has one that has not been reviewed since it was first signed — now is the time to address it.
What About Joint Ventures?
A similar set of principles applies to joint venture agreements, where two or more companies collaborate on a project or venture. The commercial and legal risks of a joint venture without a proper governing agreement are just as significant as running a company without a shareholder agreement.
