Shareholder Agreement Disputes
Disputes over shareholders’ agreements and articles of association
Shareholder agreement disputes often begin with a document that was meant to prevent them. When one goes wrong, it becomes the battleground for them.
Most private Irish companies are governed by two key documents: the company’s constitution (articles of association) and, very often, a separate shareholders’ agreement dealing with matters the constitution does not cover; voting thresholds, reserved matters, exit mechanisms, and what happens if a shareholder wants to leave, is forced out, or dies.
Disputes commonly arise not because these documents don’t exist, but because they are ambiguous, out of date, or simply ignored when it matters. Our team advises on both the enforcement of these agreements and, working with our Corporate & Commercial department, the drafting of new or updated agreements to prevent future disputes.
Common Sources of Shareholder Agreement Disputes
- Pre-emption rights – a shareholder transfers or attempts to transfer shares to a third party without first offering them to existing shareholders as required
- Reserved matters and consent rights – decisions requiring shareholder or investor consent (borrowing, new share issues, changing the business, related-party transactions) are taken without the required approval
- Drag-along and tag-along clauses – disputes over whether a sale triggers these rights, and on what terms
- Non-compete and non-solicitation clauses – a departing shareholder sets up a competing business or approaches clients or staff in breach of restrictive covenants
- Good leaver / bad leaver provisions – disagreement over how a departing shareholder’s exit is classified, which can significantly affect the value they receive for their shares
- Deadlock and dispute resolution clauses – mechanisms such as expert determination, mediation or “Russian roulette” clauses are triggered, disputed, or ignored
- Conflicts between the articles and the agreement – where the two documents say different things, or the articles have not been updated to reflect a later agreement

Shareholder Agreement Disputes – Frequently Asked Questions
The articles are a public, constitutional document registered with the Companies Registration Office and binding on the company and all shareholders. A shareholders’ agreement is a private contract, usually only between the shareholders who sign it, and can cover matters the articles don’t — or contain terms the parties prefer not to make public.
This is a common and genuinely difficult issue. Generally, the articles govern the company’s own actions (such as share transfers and general meetings), while the agreement is enforceable as a contract between its signatories. Getting this wrong can significantly affect what remedy is actually available, which is why early advice matters.
Yes, if validly drafted and triggered, a drag-along clause can compel minority shareholders to sell their shares alongside a majority sale, usually on the same price and terms. Disputes typically centre on whether the trigger conditions were properly met and whether the terms offered were genuinely the same.
Depending on urgency, options range from a warning letter, to an injunction restraining the competing activity, to a damages claim for losses caused. Non-compete clauses must be reasonable in scope, duration and geography to be enforceable, so we assess enforceability as a first step.
If you have more than one shareholder, in almost all cases yes. Without one, disputes fall back on the articles (which are often generic) and general company law, which frequently leaves gaps — particularly around exit, deadlock and valuation — that a properly drafted agreement would have closed off in advance.
Not automatically, but many shareholders’ agreements contain a mandatory dispute resolution clause requiring mediation or expert determination before court proceedings can be issued. We check this first, as failing to follow a contractual process can cause delay or cost consequences later.
