When a business has more than one owner, the relationship can be straightforward while everyone agrees. The real test comes when the business needs more money, a shareholder wants to sell, directors disagree, or one owner stops contributing as expected.

A shareholding agreement, also commonly called a shareholders’ agreement, gives business owners a clear framework for dealing with those moments before they become personal, expensive or disruptive. It is not just a document for large companies or investors. For many Australian small businesses, it is an important part of protecting the company, the owners and the value they are building together.

What a shareholding agreement does

A shareholding agreement is a private agreement between some or all shareholders, and often the company itself. It records how the owners intend to work together, make major decisions, deal with shares and resolve disputes.

It is particularly useful where shareholders have different roles. For example, one shareholder may run the business day to day, another may provide capital, and another may bring industry contacts or specialist expertise. Even where ownership is equal, expectations can differ significantly.

A well-prepared agreement can help answer practical questions such as:

  • Who can make operational decisions?

  • Which decisions need shareholder approval?

  • Can a shareholder sell shares to an outside party?

  • What happens if an owner dies, becomes ill or wants to leave?

  • How will the business be valued if shares are bought or sold?

  • What happens when shareholders cannot agree?

  • What are each owner’s obligations to the business?

The agreement should be written to suit the company’s actual circumstances, rather than copied from a generic precedent. A family business, professional practice, startup and established trading company will often need very different provisions.

Shareholders own shares in the company, rather than owning the company’s individual assets. Directors generally manage the company’s business, while shareholders exercise rights attached to their shares and vote on certain company matters. The company’s constitution, the replaceable rules in the Corporations Act and any shareholders’ agreement can all affect those rights and responsibilities.

How it works alongside the company constitution

A shareholding agreement is not a substitute for the company constitution. These documents have different roles and need to work together.

Every Australian company must have rules for its internal management. Depending on the company, those rules may come from the replaceable rules in the Corporations Act, a constitution, or a combination of both. The replaceable rules provide a basic framework for matters such as directors, meetings, shares and dividends.

A constitution has a particular legal role within the company structure. It operates as a statutory contract involving the company, its members, directors and secretary. A shareholding agreement is generally a separate private contract, so its effectiveness depends heavily on who signs it and how its terms are drafted.

For that reason, it is important to check for consistency across:

  • the company constitution;

  • the shareholding agreement;

  • share issue documents;

  • director service agreements or employment agreements;

  • loan agreements;

  • trust deeds, where shares are held by a trustee;

  • buy-sell arrangements and insurance policies.

If the constitution allows an action but the shareholders’ agreement restricts it, the parties may still create a contractual dispute by acting contrary to the agreement. Conversely, an agreement cannot safely be relied on to bypass requirements that apply under the Corporations Act or the company’s constitution.

Where key share transfer, voting or governance rules are intended to apply at a company level, it may be appropriate for the constitution and agreement to be aligned. Legal advice is valuable here, particularly where there are different share classes, external investors or family trusts involved.

Ownership, roles and decision-making rules

One of the most important jobs of a shareholding agreement is to make ownership and authority clear.

The agreement should identify each shareholder, the shares they hold and the rights attached to those shares. If the company has more than one class of shares, the arrangement should clearly state matters such as voting rights, dividend rights, entitlement on a winding up and any conversion or redemption features.

It should also distinguish between ownership and management. A shareholder is not automatically entitled to run the business simply because they own shares. Equally, a director may have duties and decision-making responsibilities even where they hold few or no shares.

Common areas to address include:

  • appointment and removal of directors;

  • board composition and voting arrangements;

  • whether a shareholder is expected to work in the business;

  • responsibilities of owner-managers;

  • remuneration, director fees and dividends;

  • access to financial information and management reports;

  • authority to sign contracts, borrow funds or commit company expenditure;

  • treatment of confidential information and intellectual property.

The agreement should also identify “reserved matters”. These are significant decisions that cannot be made by one director or a simple majority without a higher level of shareholder approval.

Reserved matters commonly include:

  • issuing new shares or changing the share structure;

  • borrowing above an agreed level;

  • giving guarantees or security;

  • selling a major business asset;

  • changing the nature of the business;

  • approving a major acquisition;

  • declaring dividends;

  • employing or dismissing a key executive;

  • entering into related-party transactions;

  • changing the company constitution;

  • selling the business or undertaking a major restructure.

The right approval threshold will depend on the business. A minority shareholder may seek protection against decisions that could dilute their interest or change the direction of the company. Majority shareholders may want enough flexibility to operate the business without needing unanimous approval for every commercial decision.

The goal is not to make decision-making difficult. It is to ensure that the decisions with the greatest impact are made deliberately and transparently.

Rules for selling, transferring and valuing shares

A business owner may assume they can sell their shares whenever they choose. In practice, an unrestricted sale can create serious problems for the remaining owners. A shareholder could otherwise attempt to sell to a competitor, an unsuitable investor or someone with no relationship to the business.

A shareholding agreement can set out a clear process for transfers. This may include a requirement that shares are first offered to existing shareholders before being offered to another buyer. Proprietary companies may also be subject to company rules dealing with pre-emption on the issue of shares, so the agreement and constitution should be checked together.

Useful transfer provisions may cover:

  • voluntary sale of shares;

  • retirement from the business;

  • resignation from employment or directorship;

  • death or permanent incapacity;

  • bankruptcy or insolvency of a shareholder;

  • divorce or family law proceedings affecting share ownership;

  • breach of the agreement;

  • a shareholder competing with the business;

  • attempted transfer without consent.

The agreement should also establish how shares will be valued. This is often where disputes become most difficult.

Possible valuation approaches include:

  • an agreed formula;

  • a multiple of earnings, adjusted for the nature of the business;

  • net asset value;

  • an independent valuation;

  • a valuation mechanism agreed when the business was established;

  • a process under which each party can propose a value and trigger a sale or purchase process.

There is no universally correct method. What matters is that the process is commercially sensible, sufficiently detailed and appropriate for the business.

Owners should think carefully about whether the value should take account of goodwill, work in progress, unpaid customer debts, business debt, owner loans, surplus cash and assets that are not essential to the trading business. The agreement should also deal with the timing of payment. A buyer may need to pay over time, particularly where the remaining owners are purchasing the departing owner’s shares.

Funding, profits and shareholder obligations

Many business disputes arise because the company needs cash and the owners have different views about who should provide it.

A shareholding agreement can clarify how further funding will be handled. For example, it may state whether additional funds are to be contributed as equity, shareholder loans or external borrowings. It can also address whether shareholders are required to contribute proportionately, and what happens if one owner cannot or will not contribute.

This is particularly important where one shareholder regularly puts money into the company while another contributes time or expertise. Without clear records and agreements, there can be uncertainty about whether funds are loans, capital contributions, payments for services or amounts that should be repaid.

The agreement may also address:

  • when shareholder loans can be repaid;

  • whether loans rank equally between shareholders;

  • whether interest is payable on loans;

  • whether a shareholder must provide a personal guarantee;

  • whether guarantees should be shared proportionately;

  • how profits are retained or distributed;

  • the company’s dividend policy;

  • treatment of unpaid shareholder entitlements.

Tax and accounting records need to support the commercial arrangement. For example, payments, loans and benefits involving private companies and shareholders can have tax consequences, including under the rules commonly known as Division 7A. The legal agreement, company accounts, loan documentation and actual conduct should all tell a consistent story.

A practical agreement should not force a company to pay dividends or repay loans where doing so would be commercially imprudent or inconsistent with directors’ duties. It should instead provide a clear decision-making process and set expectations around financial reporting, cash flow and reinvestment.

Planning for deadlock, disputes and unexpected events

A deadlock happens when the people with decision-making power cannot reach agreement. It is especially common in businesses with equal ownership, but it can also arise where a minority shareholder has veto rights over major decisions.

Ignoring deadlock risk can leave a company unable to borrow, appoint key staff, approve a budget or respond to an urgent commercial issue.

A shareholding agreement can include an escalation process, such as:

  1. A good-faith discussion between the shareholders.

  2. A meeting of directors with written information about the issue.

  3. Mediation with an independent mediator.

  4. An agreed buy-out process if the dispute cannot be resolved.

  5. Court action only as a last resort.

The right process will depend on the business and the relationship between the owners. A family company may benefit from a staged process that preserves relationships. A business with external investors may need tighter rights to prevent prolonged disruption.

The agreement should also address unexpected events. Death, incapacity, serious illness and relationship breakdown can affect both ownership and business continuity. Buy-sell arrangements may be relevant, particularly where the business would struggle to fund a share buy-out without insurance proceeds or agreed payment terms.

A simple scenario

Consider two shareholders who each own half of a growing services company. One works full time in the business, while the other has gradually become less involved but still expects equal dividends. The company then needs funds for new staff and technology, but the inactive shareholder does not want to contribute more money.

Without an agreement, the owners may disagree about whether to borrow, issue shares, retain profits or sell part of the business. With a carefully drafted shareholding agreement, they may already have rules for further funding, dividend decisions, reserved matters, valuation and a process for one shareholder to buy out the other.

The agreement does not guarantee agreement between the owners. It does, however, give them a process to follow when the relationship is under pressure.

Keeping the agreement current as the business changes

A shareholding agreement should be reviewed when the business changes, not only when there is a dispute.

Common trigger points include:

  • bringing in a new shareholder or investor;

  • issuing new shares;

  • changing share classes;

  • appointing or removing a director;

  • a shareholder starting or leaving employment with the company;

  • acquiring another business;

  • moving from a startup phase to a more established operation;

  • introducing a family trust or SMSF as a shareholder;

  • obtaining significant finance;

  • planning a sale, succession or restructure.

New shareholders should generally be required to sign a deed of accession or similar document before becoming part of the ownership group. This helps ensure they agree to the existing shareholding arrangements rather than creating a gap in the agreement.

Company records also need attention. ASIC requires companies to keep shareholder and share details up to date in the company’s share register, and certain changes in shares or shareholding may need to be notified to ASIC.

The agreement should be read alongside the company’s financial records, ASIC records and tax position. If shares are held through family trusts, companies or other entities, the ownership structure needs to be accurately reflected. A change that appears simple commercially can have broader legal, tax, duty, succession and asset-protection implications.

The key takeaway

A shareholding agreement is a practical way to document how business owners will make decisions, fund the company, share profits, transfer ownership and deal with conflict. It is most valuable when it is prepared early, while shareholders are aligned and able to discuss expectations constructively.

The agreement should be tailored to the company’s ownership structure, constitution, commercial plans and tax position. It should also be reviewed as the business grows or ownership changes.
