Shareholder Agreements: The Document You Hope You Never Need

Why the Corporations Act Is Not Enough

The Corporations Act 2001 (Cth) provides a default legal framework governing the relationships between shareholders and the company, the rights and duties of directors, and the mechanisms for making corporate decisions. For many large public companies, the Act's framework – supplemented by a detailed constitution – is broadly workable. For small private companies with two to five shareholders who are also directors and actively involved in running the business, the Act's default provisions are often wholly inadequate for managing the practical realities of co-ownership. The Act does not, for example, provide any mechanism for resolving deadlocks between equal shareholders, impose any obligation of good faith between shareholders in their dealings with one another, or restrict a shareholder from selling their shares to an unknown third party without the consent of the other shareholders. A shareholder agreement fills these gaps.

A shareholder agreement is a private contract between all or some of the shareholders of a company. Unlike the company's constitution, it does not need to be filed with ASIC and its contents are not publicly available. It can contain provisions that are not permitted in a constitution under the Corporations Act, and it can be amended with the consent of the parties without going through the formal process of altering the constitution. It sits alongside the constitution as the primary document governing the internal affairs of the company.

Key Provisions Every Shareholder Agreement Should Address

Share transfer restrictions are among the most important provisions in any shareholder agreement. Without them, a shareholder can sell their shares to anyone – a competitor, a stranger, or a person the remaining shareholders would never have agreed to bring into the business – without needing the consent of the other shareholders. A right of first refusal requires a selling shareholder to offer their shares to the existing shareholders before offering them to an external buyer. A tag-along right allows minority shareholders to participate in a sale by a majority shareholder on the same terms. A drag-along right allows majority shareholders to compel minorities to sell in connection with a sale of the whole company. Each of these mechanisms serves a distinct purpose, and the appropriate combination depends on the structure and objectives of the specific business.

Deadlock resolution provisions are critical in companies with equal shareholdings. If two 50% shareholders reach an impasse on a fundamental decision and there is no mechanism in the agreement for resolving that deadlock, the company can become paralysed – and the only recourse may be costly litigation or winding up. A well-drafted shareholder agreement will typically include an escalating dispute resolution procedure (mediation before arbitration or litigation), and may include a "shotgun" or "buy-sell" clause as a last resort, which allows either shareholder to set a price at which they will either buy the other out or sell their own shares to the other at that price.

Funding Obligations and Exit Mechanisms

Many shareholder disputes that come through our door are rooted in disagreements about funding. One shareholder believes the business needs capital investment; the other disagrees or cannot afford to contribute. A shareholder agreement can address this by establishing clear rules about how additional funding needs are to be met – whether by proportional capital contributions, shareholder loans, or external borrowing – and what happens if a shareholder refuses or is unable to meet a call for additional capital. Provisions dealing with the dilution of non-contributing shareholders, or the conversion of shareholder loans to equity, can prevent these disputes from becoming existential.

Exit mechanisms – the agreed process by which a shareholder can leave the business – are equally important. These include provisions dealing with retirement, death, permanent disability, and involuntary departure (for example, where a shareholder-director is removed from their role). Each of these events needs a clear and agreed mechanism for valuing the departing shareholder's interest and effecting a buy-out. Without such mechanisms, the departure of a shareholder can trigger litigation over valuation and the right to remain as a shareholder without any active role in the business. The time to negotiate and agree on these provisions is at the outset of the relationship, not when the relationship is under strain.
