Shareholders Agreement Lawyers for Australian Companies
Going into business with someone is easy on day one: everyone agrees, everyone’s optimistic, and nobody wants to talk about what happens if it sours.
A shareholders agreement is the document you have drafted while everyone is on the same page, so that money, control and exits are already settled if that ever changes.
What is a shareholders agreement?
It’s a contract between the owners of a company (and usually the company itself) that sets out how the company will really be run: who decides what, how shares can be bought and sold, what happens when someone wants out, and how deadlocks get broken. It works alongside your company constitution: we’ve written about why small businesses need a tailored constitution, and the two documents are designed together.
What should yours cover?
- Decision-making: which decisions need everyone, which need a majority, and which the directors handle day to day.
- Money: how funding works when the company needs more, and what happens when a shareholder won’t (or can’t) contribute.
- Shares and exits: pre-emptive rights, how a departing shareholder’s shares are valued and sold, and drag-along and tag-along rights (mechanisms that let a majority sell the whole company, or let minorities join a sale on the same terms).
- Founder commitments: vesting arrangements so a co-founder who leaves early doesn’t keep a full slice of everyone else’s future work.
- Deadlock and disputes: a clear path when 50/50 owners disagree, so the business doesn’t stall while the argument runs.
- Restraints: what a departing shareholder can and can’t do next.
When should you put one in place?
Ideally when the company is set up, alongside your company registration and constitution, or whenever a new shareholder comes in. In practice, the second-best time is now: these agreements are cheapest and easiest to negotiate before there’s a live disagreement to negotiate around. If you’re still choosing between structures, start with our business structure advice.

Frequently asked questions
We’re 50/50 partners and get along well. Do we still need one?
You’re exactly who these agreements are for. A 50/50 company with no deadlock mechanism has no way to break a genuine disagreement, and the fallout can paralyse or destroy an otherwise healthy business. Agreeing the rules now costs a fraction of a dispute later.
Isn’t the company constitution enough?
They do different jobs. The constitution governs the company’s internal machinery; the shareholders agreement is a private contract between the owners covering the commercial deal: exits, valuations, funding obligations and restraints. Most small companies with more than one owner benefit from both, drafted to work together.
What about business partners who aren’t in a company?
If you’re in a partnership rather than a company, the equivalent document is a partnership agreement, and the same logic applies. We draft those too: start with our business structure page.
