This article is for Irish business co-founders who are facing tension about ownership or worried about what happens if one founder wants to leave.
If you're wondering how to handle a co-founder exit without destroying your business or ending up in expensive legal battles, this guide covers shotgun clauses, good leaver/bad leaver provisions, and what happens if you don't have proper exit mechanisms in place.
Key Takeaways
• Good leaver and bad leaver provisions determine exit value: good leavers receive fair market value, bad leavers get nominal value.
• Shotgun clauses force fair pricing by requiring the receiving shareholder to either sell or buy at the stated price.
• Without proper exit mechanisms, you face expensive court proceedings or business deadlock that destroys company value.
• Mediation resolves founder disputes in weeks at lower cost than litigation, which takes months or years.
• Section 569 winding up petitions are the nuclear option: all assets get sold and business value evaporates through liquidation.

What Happens When a Co-Founder Wants Out?
A co-founder wanting to leave should be a straightforward transaction. You agree on a fair price, transfer the shares, and move forward.
The reality is often more complex. One founder might believe their shares are worth €200,000 while the other values them at €50,000.
Without proper mechanisms to resolve this disagreement, you can end up in a stalemate that damages the business and costs everyone money.
The Companies Act 2014 provides the legal framework for share transfers and shareholder rights. It allows shareholders to transfer their shares subject to any restrictions in the company's constitution.
This is where shareholder agreements become critical. The constitution might restrict transfers to third parties but say nothing about disputes between existing shareholders.
Why Fair Exit Terms Matter for Your Business
Founder disputes drain resources from the business. While you're arguing about valuation, competitors are moving ahead. Customers sense instability.
Employees start looking elsewhere. The longer the dispute continues, the more value the business loses.
Beyond the immediate business impact, unresolved founder disputes create ongoing legal costs. These costs come directly from company funds or personal resources that could be invested in growth.
What Are Good Leaver and Bad Leaver Provisions?
Good leaver and bad leaver provisions are clauses in a shareholder agreement that set out what happens when a shareholder exits — and how much they get paid for their shares.
Here’s the difference:
Good leaver: leaves on acceptable terms, such as:
- Retirement
- Resignation agreed by the board
- Illness or circumstances beyond their control
Bad leaver: exits due to serious issues, including:
- Gross misconduct
- Material breach of duties
- Resigning without proper notice
The distinction matters because it determines share value on exit. Good leavers typically receive fair market value for their shares.
Bad leavers might receive only nominal value or the lower of market value and original purchase price.
These provisions must be clearly defined in your shareholder agreement before disputes arise.
How Does a Shotgun Clause Work?
A shotgun clause is a contractual mechanism where one shareholder offers to buy the other's shares at a stated price.
The receiving shareholder must either sell their shares at that price or buy the offering shareholder's shares at the same price.
This forces both parties to name a genuinely fair price because they might end up on either side of the transaction.
The practical effect is powerful. For example:
- If you own 50% of a company and offer to buy your co-founder's 50% for €100,000, they can respond in two ways.
- They can sell their shares to you for €100,000, or they can buy your shares for €100,000.
- You need to be confident that €100,000 represents fair value because you might become the seller.
The Companies Act 2014 doesn't specifically provide for shotgun clauses. They exist purely as contractual terms in shareholder agreements.
Understanding Russian Roulette Mechanisms
Russian roulette mechanisms operate similarly to shotgun clauses but with higher stakes. The work as follows:
- One shareholder makes an offer to purchase all shares in the company at a specific price per share
- The other shareholder must either sell all their shares at that price or buy all the offering shareholder's shares at that price
- Unlike shotgun clauses which allow 50-50 splits, Russian roulette forces a complete exit by one party
The name reflects the high-stakes nature. You need absolute confidence in your valuation. Either you exit completely, or the other founder exits completely. There's no middle ground.
This mechanism works best when both shareholders have roughly equal shareholdings and equal financial resources to fund a complete buyout.
Implementation requires careful drafting. Your shareholder agreement must specify the exact procedure including notice requirements, payment terms, and completion deadlines.
When Should You Try Mediation First?
Mediation involves a neutral third party helping founders reach agreement without court involvement. The mediator doesn't impose a solution but facilitates negotiation between parties.
This approach works particularly well for founder disputes because it preserves business relationships and allows flexible solutions that courts can't order.
Cost provides a major advantage. Professional mediation for a founder dispute costs significantly less than legal proceedings. Even if mediation fails, you've only spent a few thousand before proceeding to more expensive options.
Speed matters too. Mediation can resolve disputes in weeks while court proceedings take months or years. Mediation offers a faster path to resolution.
For founders, mediation represents a realistic chance of resolving disagreements without destroying business value through lengthy litigation.
What Happens Without Proper Exit Mechanisms?
Without shotgun clauses, Russian roulette provisions, or clear leaver terms, you face limited options. You can negotiate voluntarily, but if the other founder won't engage reasonably, you're stuck.
The Companies Act 2014 provides some remedies, but they're expensive and time-consuming.
Section 212 allows minority shareholders to petition the court for relief from oppression. The court can order the majority shareholder to purchase minority shares at fair value.
However, "oppression" requires proof that company affairs are conducted in a manner oppressive to shareholders or in disregard of their interests. This is a high legal threshold requiring extensive evidence.
Section 569 permits shareholders to petition for company winding up where it is just and equitable to do so. This is the nuclear option. If the company winds up, all assets get sold, debts get paid, and remaining funds distribute to shareholders. Nobody wins because business value evaporates through the liquidation process.
The practical reality without proper mechanisms is deadlock:
- One founder can't force the other to sell
- The company can't function effectively with warring founders
- Business value declines as the dispute continues
- Eventually, someone backs down, agrees to expensive litigation, or the company fails entirely
