Most businesses don’t fail because the market turned or the product stopped selling. A surprising number unravel from the inside, over ownership, control, money and the value built over years can evaporate in months. The trigger is almost always something that could have been settled in writing long before it became a crisis.
That something is the shareholders agreement. When it’s missing, generic, or treated as an afterthought, the same expensive problems surface again and again. And by the time they surface, the cheap fix is gone.
Carlyon Ward has seen how quickly things unravel when the legal foundations are an afterthought. Here are the mistakes business owners make most often and why each one can cost millions.
Mistake #1: Treating the agreement as a formality
The single most dangerous mistake is treating a shareholders agreement as a box-ticking exercise rather than a business-critical tool.
Founders pour their energy into vision, growth and opportunity. The legal scaffolding that protects all of it gets pushed to the bottom of the list something to sort out “later,” once there is more time and more money on the line.
But a well-drafted shareholders agreement is not paperwork. It is a safeguard for the business, for every shareholder, and for the company’s future. The owners who understand this build the agreement while relationships are good and interests are aligned. The ones who don’t end up negotiating under pressure, often through lawyers, often in court.
Mistake #2: Relying on a generic template
A downloaded template feels like a sensible shortcut. It is one of the most expensive shortcuts a business can take.
Every business is different. A shareholders agreement has to be customised to the specific company, its people and its risks, not pulled off a shelf. The gaps in a generic document are invisible right up until the moment they matter, and by then it is too late to fix them cleanly.
Carlyon Ward stresses that a properly tailored agreement should address all of the following:
• Shareholder rights and obligations
• Board structure and decision-making authority
• Exit and transfer provisions
• Share valuation mechanisms
• Deadlock resolution
• Confidentiality and restraint clauses
• Dividend policy
• Dispute resolution
A template might mention a few of these. It will rarely tailor any of them to how your business actually works.
Mistake #3: No exit or buy-out clause
Of all the omissions, this is the most common and the most costly.
Ask a simple question: what happens if a shareholder wants out? Or passes away? Or goes through a divorce? Without clear rules on how shares are valued and transferred, the answers get decided by circumstance rather than design.
The consequences are severe. The business can be paralysed while ownership is in limbo, or a stake can fall into the hands of an unwanted third party a competitor, an ex-spouse, or an heir with no interest in the company.
Pre-emptive rights, which give existing shareholders first refusal on any shares being sold, are essential. So are drag-along and tag-along provisions, which protect both majority and minority shareholders during a sale. These are not optional extras. They are the difference between an orderly exit and a crisis.
Mistake #4: Ignoring deadlock until it’s too late
Deadlock provisions are routinely overlooked, usually until two co-founders are actively paralysing the business they own together.
Without a clear deadlock mechanism, a disagreement about who gets to decide what can stall a company entirely. Nothing moves. Suppliers go unpaid, deals go unsigned, and the value built over years starts to leak away.
A strong agreement removes the ambiguity in advance. It sets out which decisions require unanimous consent, what directors are free to decide independently, and exactly what process kicks in when the board is gridlocked. The goal is simple: no single dispute should ever be able to freeze the whole business.
Why Carlyon Ward says the maths is so one-sided
Businesses without a solid shareholders agreement regularly end up in the worst possible place, Supreme Court litigation.
The real-world examples follow a pattern: companies paralysed by director deadlock; shares sold to an outsider because no pre-emptive right existed; intellectual property ownership disputes that surfaced at exactly the wrong moment and compromised sale negotiations.
Each of these was preventable. And the cost comparison is stark. Investing a few thousand dollars in proper planning at the outset can save hundreds of thousands, sometimes millions, in litigation, lost deals and destroyed value later.
That is the part owners tend to miss. The agreement does not feel expensive because it failed. It feels expensive because, done right, you never see the disasters it quietly prevented.
The Takeaway
A shareholders agreement is cheapest, easiest and most effective to put in place when everyone is getting along and the business is doing well, which is exactly when it feels least urgent.
Get it customised. Cover exits, valuation, deadlock and disputes before they happen. Treat it as the business-critical document it is, not a formality to rush through.
The owners who do this rarely think about their shareholders agreement again. The ones who don’t often think about little else, from the other side of a courtroom.
