When people go into business together, they are usually optimistic and aligned. That is exactly the right time to write down the rules — before money, disagreements, or life events strain the relationship. A shareholder agreement is the contract among a corporation's owners that sets those rules in advance. Without one, owners fall back on the default statutory rules, which may not fit their intentions and often leave critical questions unanswered.
What a shareholder agreement typically covers
- Governance and decision-making: how directors are appointed, what decisions need special approval, and how deadlocks are broken.
- Transfer restrictions: limits on selling shares to outsiders, rights of first refusal, and drag-along and tag-along rights that coordinate a sale.
- Buy-sell provisions: mechanisms such as a "shotgun" clause, where one owner names a price and the other must either buy or sell at that price, to resolve an impasse.
- Exit events: what happens on a shareholder's death, disability, retirement, or departure — often tied to insurance and a valuation method.
- Funding and returns: how the business will be financed, whether owners must contribute more capital, and how and when dividends are paid.
- Dispute resolution: how disagreements are handled, often through mediation or arbitration rather than litigation.
Unanimous shareholder agreements
Corporate statutes recognise a special kind of agreement: a unanimous shareholder agreement (USA), signed by all shareholders, which can go further than an ordinary agreement. A USA can restrict or transfer some of the directors' powers to the shareholders themselves, effectively reshaping how the corporation is governed. Because it changes where decision-making authority sits, it is a powerful and carefully-used tool.
Why it is worth doing early
The value of a shareholder agreement shows up precisely when things go wrong — a founder wants out, an owner dies, two equal partners deadlock, or someone wants to sell to an outsider the others distrust. An agreement negotiated while everyone is on good terms produces fair, pre-agreed answers to these situations. Negotiating them in the middle of a dispute is far harder and more expensive.
- Address exits and death before they happen, ideally with a valuation method everyone accepts.
- Decide how major decisions are made and how deadlocks break.
- Coordinate the agreement with the corporation's articles and by-laws so they do not conflict.
