Most shareholder disputes don’t start with a legal argument. They start with a sentence like: “That isn’t what we agreed.”
The trouble is that nobody wrote it down. Most owner-managed companies don’t have a shareholders’ agreement. They have a good working relationship, a conversation from years ago, and a set of off-the-shelf articles last read on the day of incorporation. That holds up well, right until the day it doesn’t.
The day it stops holding up tends to look like one of these: a founder wants out, two equal partners stop agreeing, a shareholder dies, a marriage ends, or an investor arrives wanting terms. At that point the agreement you wish you had is the one document you can no longer put in place, because the person who would need to agree it is the person you are now negotiating against.
A shareholders’ agreement is cheap insurance, bought while everyone is still getting on. Here is what it does, and why your articles and the Companies Act don’t do it for you.
Your articles and the Companies Act only go so far
Every company has articles of association and sits under the Companies Act 2006. Together they cover the mechanics: how shares are issued, how directors are appointed, how meetings and votes work. Most small companies adopt the model articles more or less unchanged and leave it there.
What that framework does not do is govern the relationship between you as shareholders. It does not say what happens to someone’s shares when they leave, fall out, or die. It gives the other owners no clear right to head off a sale to a competitor. It does not protect a minority shareholder from being outvoted on everything that matters. And it is public: your articles sit on the Companies House register for anyone to read.
A shareholders’ agreement is private, and it is a contract between the owners. That combination is what lets it do the work the articles can’t.
The “we’re all mates” problem
The most common reason owners give for not having one is that they trust each other. That is exactly the point. An agreement is not a sign of distrust; it is what protects a good relationship from the situations nobody planned for. Trust handles the day-to-day. It does not handle a death, a divorce, a deadlock or a buyer. Those are the moments an agreement is for, and by definition they tend to arrive when goodwill is already under strain.
What a good agreement actually does
A handful of provisions earn their place in almost every agreement.
Controlling who can own shares. Pre-emption rights mean shares must be offered to existing shareholders before they can go to an outsider. You decide who can sit on your share register.
Drag-along and tag-along. Drag-along lets a selling majority require the minority to sell too, on the same terms, so a clean sale of the whole company can actually happen. Tag-along is the mirror image: if the majority sells, the minority can insist on being bought out at the same price. One enables the deal; the other protects the smaller holder.
Good leaver, bad leaver. When a shareholder who also works in the business leaves, what happens to their shares? A well-drafted agreement says it depends how they go. Leave on good terms and you are bought out at fair value; leave in breach and you get cost, or less. Without this, a departing shareholder can simply keep their stake, and their say.
Breaking a deadlock. In a 50/50 company, a single disagreement can freeze the business completely. An agreement sets out how to break the tie before it becomes terminal, whether through an agreed escalation process, a buy-out mechanism, or a route of last resort.
Reserved matters. A short list of the big decisions, taking on debt, issuing new shares, changing the business, that need agreed consent rather than a simple majority. This is how a minority shareholder gets real protection on the things that matter, without trying to run the company day to day.
Dividends, share classes and the tax that follows
Different classes of share, often called alphabet shares, let you pay different dividends to different shareholders. That is useful for bringing in family members or rewarding key people, and it interacts directly with personal tax planning around the balance of dividends and salary. It also draws HMRC attention if it is done clumsily, and the rules on shifting income between spouses are not as simple as they look. This is the point where the legal structure and the tax planning have to be designed together, which is where our tax colleagues down the corridor earn their keep.
The moments to revisit it
An agreement is not a do-it-once document. It is worth looking at again whenever the picture changes: a new investor, who will want their own protections; new shareholders such as key employees taking equity; the death of a shareholder, where a cross-option arrangement backed by life cover keeps the shares in safe hands and the family liquid; or a divorce, where shares can become a matrimonial asset. Each of these is far easier to handle if the agreement saw it coming.
And if a sale is on the horizon
This matters twice over when you are heading towards an exit. A buyer’s lawyers will want a clean, current agreement and articles that work for a sale, with drag-along rights that let the deal complete without a hold-out. We set out the wider groundwork in our recent guide on preparing a business for sale; getting the shareholders’ agreement right is one of the first jobs in that process.
The takeaway
Put a shareholders’ agreement in place when nobody needs it and everyone is getting on. Done then, it is straightforward and uncontroversial. Done in the middle of a dispute, it is neither.
If you don’t have one, or yours hasn’t been looked at in years, we are happy to take a look. A short call usually beats a long email.
