It starts with a disagreement. One shareholder wants to sell the company. Another wants to keep building. You're deadlocked. Neither shareholder can overrule the other, so nothing happens. The company stalls. Everyone is frustrated.
This is a deadlock, and it's a real problem in companies with multiple founders or significant shareholders. Without a way to resolve it, deadlock can paralyze the business.
That's why deadlock resolution clauses exist. They're mechanisms built into shareholders agreements that provide a way to break a deadlock and move forward. Get them right and you've protected yourself if things go wrong.
Why deadlock clauses matter
Without a deadlock clause, if shareholders disagree on a major decision and each has veto power, you're stuck. You can't sell the company, raise funding, change strategy, or hire a new CEO. The company is frozen.
Deadlock clauses force a resolution. They say: "If you can't agree, here's how we'll decide." This prevents paralysis and gives shareholders certainty that even if they disagree, there's a way forward.
They also protect against hostage-taking. A minority shareholder can't hold the company hostage by refusing to agree to a sale or change everyone else wants.
The main deadlock resolution mechanisms
Shotgun clause (Russian roulette). If deadlock occurs, one shareholder makes an offer to buy the other's shares at a specific price. The other shareholder has two choices: accept the offer, or force the first shareholder to sell them their shares at the same price.
Example: "Shareholder A says: 'I'll buy your shares for £500,000.' Shareholder B can either sell for £500,000 or buy A's shares for £500,000."
Why it works: The shareholder making the offer has to offer a fair price, because they have to be willing to accept that price if the other shareholder inverts the deal. It incentivizes fairness.
When it's good: For founder deadlocks, especially 50/50 splits. It forces a decision quickly and fairly.
When it's bad: If one shareholder has more cash, they can simply buy out the other, which might not be what either party wants. For larger shareholder groups (3+ shareholders), it gets complicated.
Expert determination. A neutral third party (accountant, business valuer, arbitrator) makes the decision on the disputed issue. The shareholders submit their arguments, the expert decides, and the decision is binding.
Example: "Shareholders disagree on whether to sell the company. An independent business valuation expert values the company. If the valuation is above £5 million, the company is not for sale. Below, it's offered for sale."
Why it works: It removes personal conflict and brings in objective judgment. The expert isn't incentivized to favor either side.
When it's good: For factual disputes (valuation, company worth) or complex decisions that require expertise. Good when shareholders disagree on the facts but might accept expert judgment.
When it's bad: It's slower than shotgun (expert determination takes weeks). It costs money. And if shareholders don't respect the expert, they might still be resentful.
Put-call option. One shareholder has the option to either put (sell) their shares to the other shareholder or call (buy) the other's shares, but not both. If the shareholders are deadlocked, the non-proposing shareholder chooses which option applies.
Example: "Shareholder A wants to sell; Shareholder B wants to keep going. A proposing the price, B chooses: either B buys A's shares at that price, or B sells their shares to A at that price."
Why it works: Similar to shotgun, it incentivizes fair pricing. The proposer knows the other shareholder will choose the option favorable to them.
When it's good: Similar uses as shotgun, with slightly less adversarial feel because it's more nuanced.
Mediation and escalation. Before triggering a formal deadlock resolution mechanism, require parties to attempt mediation. "If shareholders disagree, they must attempt resolution through mediation with an independent mediator within 30 days. If mediation fails, [other mechanism] applies."
Why it works: Many deadlocks arise from miscommunication, not fundamental disagreement. Mediation can find common ground.
When it's good: As a first step before more adversarial mechanisms. Allows relationship-preserving resolution.
Majority vote or supermajority. Rather than giving every shareholder veto power, decisions go to a vote. A 50%+ majority (simple majority) or 66-75% (supermajority) makes the decision. No deadlock because the majority wins.
Example: "Major decisions (selling the company, raising capital, acquisitions) require approval by 75% of shareholders. Strategic decisions require 50% approval."
Why it works: Clear and simple. No mechanism needed; just vote.
When it's good: For larger shareholder groups where deadlock between equals is unlikely. Less good for equal co-founders because one shareholder can be overruled.
Forced buyout with predetermined formula. If deadlocked, one shareholder is forced to sell their shares to the other at a formula price (e.g., net assets, or 1x revenue).
Why it works: Breaks deadlock immediately and finally.
When it's good: When there's clear underperformance or one shareholder has stopped contributing. Less good for equal founders because it's arbitrary who gets forced to sell.
Which mechanism should you choose?
It depends on your circumstances:
Two equal founders. Shotgun clause or put-call option. These give both founders equal leverage and incentivize fair dealing.
Founder + investor. Expert determination or mediation. The goal is often to resolve the practical question (should we sell? should we raise more money?) rather than determine which founder "wins." Expert judgment on that question makes sense.
Three or more equal shareholders. Majority vote or mediation + expert determination. Shotgun gets complicated with multiple parties.
Unequal shareholders (e.g., 60/40). Majority vote (majority can decide) or expert determination (neutral judgment). Shotgun can be unfair to minority shareholders.
Most well-drafted shareholders agreements use multiple mechanisms depending on the dispute. For example: first mediation (30 days), then expert determination on valuation (if needed), then shotgun clause (if still deadlocked).
What decisions trigger deadlock resolution?
Not every decision should trigger deadlock resolution. Usually only major decisions:
Sale or merger of the company. Major capital raise or fundraising round. Change of business strategy or direction. Acquisition of another company. Related-party transactions or loans to shareholders. Appointment of new board members or CEO. Removal of existing board members or CEO. Major change in dividend policy. Approval of annual budget and financial targets.
Day-to-day operational decisions (hiring, marketing spend, product development) usually don't trigger deadlock clauses. Only strategic, major decisions do.
Red flags in deadlock clauses
"Deadlock applies to any decision shareholders disagree on." Too broad. Deadlock clauses should be limited to major strategic decisions. Otherwise every disagreement becomes a deadlock.
Shotgun clause with no price floor. If one shareholder can propose any price, including a very low price, that's unfair. Include a requirement that prices be based on a fair valuation method.
No timeline for deadlock resolution. If there's no deadline, deadlock can drag on indefinitely. Include a timeline: "If deadlock isn't resolved within 60 days, expert determination is triggered."
Asymmetric voting rights with no deadlock clause. If one shareholder can outvote the other on all decisions, you don't have true partnership. Either ensure equal voting rights or have a deadlock clause for major decisions.
Protecting yourself
If you're negotiating a shareholders agreement with co-founders or investors, push for deadlock resolution mechanisms that are fair to all parties. Key points:
Ensure major decisions are clearly defined. Ensure the mechanism incentivizes fair dealing (e.g., shotgun clause makes the proposer offer a fair price). Include a timeline so deadlock doesn't drag on indefinitely. Consider phased resolution (mediation, then expert determination, then binding mechanism). Make sure you understand the mechanism and what it means for you before you sign.
Getting it right
Deadlock resolution clauses are important and should be carefully drafted. Before you sign a shareholders agreement, use QuickLegalCheck to review the deadlock clause and understand how it protects you.
