Seven ways to resolve a shareholder deadlock
From a structured negotiation to a buyout or sale: the routes available when neither side can move.
BusinessBreakup disputes team · Updated September 2026A 50/50 company is designed to need agreement. When the two owners stop agreeing, nothing moves: no accounts signed, no hires approved, no contracts renewed.
The way out is not a better argument. It is choosing a route that either reopens decision-making or separates the owners. Here are the seven that are realistically available.
- Deadlock is structural: either reopen decision-making or separate the owners.
- Negotiation, mediation, deadlock clauses and governance reform keep the business intact.
- Buyout and sale are the most common commercial outcomes; winding up destroys value.
- Leverage comes from information, funding and a credible alternative.
Start by naming the type of deadlock
Some deadlocks are about a single decision, others about the whole relationship. A one-off disagreement can often be unlocked with better process - a casting vote, a chairman, an independent expert. A relationship deadlock cannot.
Our deadlock diagnostic is a quick way to see which one you are dealing with, and what the company documents actually say about breaking ties.
The routes that keep the business intact
These four leave the company trading and the value in place:
- Structured negotiation - a defined agenda, real information and a deadline.
- Mediation - a neutral third party, confidential and without prejudice.
- A deadlock clause - the mechanism the articles or shareholders' agreement already provides.
- Governance reform - new reserved matters, a chairman's vote or an independent expert.
These are usually the cheapest and quickest outcomes, and they preserve the trading relationship where that still matters.
The routes that separate the owners
Where the relationship is beyond repair, the realistic options are a buyout, a sale of the whole company, or a formal claim. A buyout is the most common: one side buys the other out at an agreed or determined value. A sale to a third party is often the cleanest exit for both.
If one side is behaving unfairly - excluding the other, diverting value, taking decisions without authority - an unfair prejudice petition may be available, and the usual remedy is an order that the shares be bought. Winding up on just and equitable grounds exists but is a last resort, because it destroys the business it is meant to value.
How to choose between them
Three questions usually decide it: what the company is worth to each side, who can fund a buyout, and how quickly the business loses value while nothing is decided?
Leverage matters too. The side with better information and a clearer alternative usually does better in negotiation. See 50/50 deadlock for how that is built.
Deadlock rarely resolves itself, and the cost is paid by the business. The useful first step is knowing which route is open to you and what it would take to make it work.

Questions people ask
- Who wins in a 50/50 deadlock?
- Neither side automatically. The documents, the conduct of each party, who can fund a buyout and the practical leverage all decide the outcome.
- Can the company be wound up?
- It can be, on just and equitable grounds, but it is usually the worst outcome commercially because the business is broken up rather than sold.
- How long does a deadlock take to resolve?
- A negotiated buyout can complete in weeks once both sides accept it is happening. A contested claim takes far longer, which is why the rate at which the business loses value matters so much.
