What it is

Facing a dispute with a company director, shareholder, or investor?

Shareholder and partnership disputes can arise for a range of reasons, but the priorities are often the same: to enable one party to leave the business, and to do so without causing suffering to the business.

Regardless of your business structure, this means finding a resolution that minimises conflict and enables both parties to move on with their lives. Our focus is on discovering the most effective pathway to this outcome.

In detail

The shareholder and partnership disputes Aptum runs

Aptum handles the full range of disputes between company directors, shareholders, investors, joint venture partners and business partners. Every matter Aptum runs falls into one of the categories below. If your dispute isn't listed, the 15-minute diagnostic call sorts out whether we can help.

Shareholder oppression claims

Applications under section 232 of the Corporations Act 2001 (Cth) for conduct that is oppressive to, unfairly prejudicial to, or unfairly discriminatory against a shareholder. Covers both minority-shareholder claims and majority-shareholder responses.

Minority shareholder disputes

Where a minority shareholder is being excluded from management, deprived of information, denied dividends, or squeezed out. Includes derivative actions on behalf of the company.

Majority shareholder buy-outs

Where the majority wants to buy out a departing or oppressive minority. Structured around business valuation and buy-out orders under sections 233 or 461 of the Corporations Act.

Partnership dissolution and buy-outs

Where a partnership needs to end and one partner needs to be bought out. Includes disputes over partnership assets, goodwill, ongoing client relationships and post-partnership restraints.

Joint venture disputes

Deadlock, breach of joint venture agreement, one party acting outside the scope of the JV, exit and control disputes. Includes both incorporated and unincorporated JVs.

Business valuation disputes

Where the exit price is contested. Valuation methodology, minority discounts, marketability discounts, expert selection, and challenging or defending a court-appointed expert.

Breach of directors' duties

Section 180-183 claims (care and diligence, good faith, use of position, use of information). Includes claims about diversion of business opportunities and self-dealing.

Breach of fiduciary duty

Between directors, partners, joint venture parties and shareholders. Includes constructive trust claims where a fiduciary has profited from the breach.

Injunctive relief and freezing orders

Urgent applications to preserve assets, restrain conduct, or prevent a party from disposing of shares while the substantive dispute is decided.

Breach of shareholders' agreement

Enforcement of dispute resolution clauses, drag-along and tag-along rights, pre-emptive rights, restraints of trade and confidentiality clauses.

Winding up on the just and equitable ground

Applications under section 461(1)(k) of the Corporations Act where the shareholders can no longer work together and no other remedy will do.

Directors' duty disputes in family-owned businesses

Includes succession-related conflicts, generational transitions and family shareholder deadlock.

In focus

Resolving shareholder oppression disputes with a focus on value

Aptum frequently helps clients resolve shareholder oppression disputes both for minority and majority shareholders.

In our experience, parties and lawyers often get caught up in spending considerable time and resources in agitating and proving the grievance (the oppression) and have real difficulty seeing beyond the oppression. The existence of oppression is rarely the real issue to resolve.

In practice, one or both of the parties will typically seek orders for a compulsory buy-out of shares in order to achieve a clean exit with the real issues to be decided being the value of the shares and which party will be the buyer (although it is typically the majority shareholder who is more readily suited to being the buyer).

The critical message is: don't allow a shareholders' dispute to destroy value. Ask first whether the relationship can be repaired in a way that would allow the company to continue to function effectively, and then very quickly turn the attention and legal costs to outcome and value.

What kind of dispute is yours?

Shareholder and partnership matters look similar from the outside but the right Aptum service depends on how the dispute is presenting.

  1. 01

    "I'm a minority shareholder being frozen out."

    Oppression claim territory. This is the right page. Aptum runs minority shareholder claims under section 232, including claims for exclusion from management, denial of information, refusal of dividends, and diversion of business opportunities.

  2. 02

    "I want to buy out or force out another shareholder."

    Also this page. Buy-out orders under section 233 or winding up on the just and equitable ground are the standard remedies where relationship breakdown means the parties can't stay together.

  3. 03

    "My business partner and I need to separate."

    Partnership dissolution and buy-out. Covered by this page. Includes goodwill, client-relationship division and post-partnership restraints.

  4. 04

What Aptum brings to a shareholder or partnership dispute

Managing Director + Co-Founder

Nigel Evans

Aptum's commercial disputes practice is led by Nigel Evans, Managing Director and Co-Founder. Nigel spent 11 years at the commercial Victorian Bar before starting Aptum. He is listed in Best Lawyers in Australia for Tax Law (2026), recognised by Doyle's Guide as a Leading Commercial Litigation and Dispute Resolution Lawyer (most recently 2026), and named a Finalist for Litigation Partner of the Year in the 2024 and 2023 Partner of the Year Awards.

Associate Director

David Adason

Nigel is supported by David Adason, Aptum's Associate Director and Practice Lead for Commercial Disputes. David has substantial commercial litigation experience including as Associate to a Justice of the Federal Court of Australia. Australasian Lawyer has named David in their list of Rising Stars, and he was most recently recognised as a Rising Star in Commercial Litigation and Insolvency Law by Doyle's Guide in 2025.

That combination of Bar-trained advocacy and structured litigation management is the difference between running a shareholder dispute the traditional way and running it Aptum's way.

Aptum runs shareholder disputes to preserve value, not to prove a point

The industry pattern in shareholder disputes is to spend the first six months building a comprehensive record of oppression, then negotiate a settlement in month twelve based on issues the buy-out was always going to have to solve anyway. Aptum works the other way. Identify the buy-out mechanics and the valuation issues at the diagnostic call. Build the pressure at the right time. Get to the terms that matter.

Bar-trained advocacy on the arguments that decide the case

Shareholder disputes turn on a small number of decisive issues: whether the conduct meets the section 232 test, whether the applicant has standing, how the shares are to be valued, and who buys whom. Nigel's Bar background means the arguments on those issues are pitched the way the Court needs to hear them from day one, not developed retrospectively.

Fee models built for mid-market businesses, not big-corporate

The traditional big-law approach to shareholder disputes prices most mid-market businesses out. Aptum uses stage-based budgets and, where the scope is defined, fixed-price options. The engagement model is designed to run the dispute at the cost the outcome can support.

Case study

An ousted business owner told he didn't have a chance, then came to Aptum

Problem. Aptum's client was forced out of his position in a co-op business in a highly specialised industry by the other shareholders. The client contacted several lawyers prior to Aptum who advised him that a shareholder oppression claim was unsubstantiated.

Aptum's role. Aptum was engaged, and based an oppression claim on a novel interpretation of the Court's powers to order compensation for our client.

Outcome. Despite this matter having been transferred to Aptum following a significant legal spend by the client, Aptum was able to strategise a legal pathway that achieved a successful outcome for the client whilst acting against a much larger firm.

Working with Aptum

What happens when you engage Aptum

Aptum runs every matter under our project management framework, with clear expectations on timing, cost and scope from the first call. Before you pay us anything, you get two points of contact, both free, so you know exactly where you stand. No surprises.

01

Value conversation (free)

If the matter is one we can help with, we bring you in for a second conversation, in person at our office or over Teams, with the practice lead who would run your matter and your client experience coordinator. You get the time and expertise of a senior practitioner who has handled matters like yours, someone with real experience who can give you genuinely useful guidance on how to approach it. Real expertise before you have committed to anything, not a fake triage.

02

Pathways assessment

Once you engage, you receive a documented strategy and a cost forecast aligned to the stages of your matter. For shareholder and partnership disputes that typically means: identify the section 232 factors and evidence, work out the valuation issues, decide between negotiated buy-out and court-ordered remedy, and plan the sequence of interlocutory steps.

03

Execution

This is the phase for drafting the originating process and supporting affidavit, filing in the Supreme Court or Federal Court under the fast-track oppression procedure, running the evidence phase, attending mediation, and (if the matter doesn't settle) preparing for hearing. Routine documented strategy. Regular communications. A relentless focus on the essential issues. Project management isn't a bolt-on at Aptum, it's a discipline embedded in every part of our practice.

In detail

How we manage cost

Shareholder and partnership disputes cover a wide cost range, from a defined buy-out negotiation to a fully contested oppression trial. What we commit to is one of our five client service promises: clear expectations as to the timing, costs and scope of our engagement, and updating those expectations as early as possible if anything changes.

Diagnostic call

A 15-minute call to work out what your dispute actually is, what a realistic outcome looks like, and what the cost-benefit of running it looks like.

Estimate and scope

Once engaged, you receive a documented strategy and a cost forecast aligned to the stages of your matter. Stage-based budgets, regular reporting, and any scope changes documented and agreed in writing. Where a matter has a tight, defined scope (a single interlocutory application, a defined mediation phase, an initial oppression demand) we can give you a fixed-price option.

Investment mindset

Aptum approaches every matter with an investment mindset: the most practical outcome in the shortest possible time, at the least possible cost, with the biggest possible return.

Outcomes

Recent matter outcomes

  1. 01

    Ousted co-op business owner achieves successful oppression outcome against a much larger firm

    Aptum's client was forced out of his position in a co-op business in a highly specialised industry by the other shareholders. He had been told by several lawyers that his oppression claim was unsubstantiated. Aptum was engaged and based an oppression claim on a novel interpretation of the Court's powers to order compensation. The matter resolved in a successful outcome, achieved against a much larger firm and after a significant prior legal spend.

  2. 02

    A shareholder exits a family business on fair terms

    A shareholder in a longstanding family-owned construction and property group sought to exit the business following a breakdown in relationships. Aptum developed and implemented a strategy to navigate the legal complexities while remaining sensitive to longstanding family dynamics. Aptum helped position the client to pursue a fair exit from the business, while protecting their interests and preserving value in a highly contentious dispute.

  3. 03

    A joint venture partner resolves a long-running property dispute

    A dispute arose between joint venture partners involved in the subdivision and sale of a development property. Aptum assumed carriage of the dispute and developed a strategy focused on resolving the tax issues, facilitating the sale of the property and progressing the various proceedings towards conclusion. Aptum helped bring a complex dispute spanning several years and multiple proceedings to a conclusion, while protecting the client's commercial interests throughout the property sale process.

FAQ

Frequently asked questions

  • How can disputes between shareholders be resolved?

    If you're involved in a dispute with another shareholder, there are various ways in which it can be resolved.

    Negotiation. The first step should always be informal discussion and negotiation. By communicating key issues and objectives early, it is often possible to reach an agreement without delving further into the litigation process. Aptum can assist in this process by investigating your position, determining reasonable objectives, and crafting the correspondence to assert your intentions.

    Turning to the agreement. Shareholder agreements will often include provisions for dealing with disputes, such as whether mediation is required and when the parties can proceed to litigation.

    Court. If the parties accept that the shareholders cannot remain together, but an agreement cannot be reached, the Court's focus shifts to who buys and who sells their shares, and at what price. A party may seek an order that they buy out the shares of the other. If the company is solvent, this is generally preferable (to both the parties and the Court) to winding up the company.

    Winding up the company. If the dispute has caused significant damage to the business, it may be appropriate for the company to enter into voluntary administration. This will be influenced by the financial strength of the company and the preferences of shareholders.

  • What is shareholder oppression?

    Shareholder oppression occurs when majority shareholders use their power or influence for their own benefit at the cost of others or the company.

    What constitutes shareholder oppression is set out in section 232 of the Corporations Act 2001 (Cth), which states that the conduct must either be:

    • Contrary to the interests of the members as a whole; or
    • Oppressive to, unfairly prejudicial to, or unfairly discriminatory against, a member or members whether in that capacity or in any other capacity.

    Contrary to some belief, oppression does not have to be unlawful, but it does need to be an abuse of power of some kind.

    Oppression may have taken place if there was a failure to pay dividends, access to company material was restricted, someone was excluded from management, or funds were used for personal reasons.

  • What is an example of shareholder oppression?

    Common examples include: a majority shareholder paying themselves excessive salaries or bonuses while refusing to declare dividends to the minority; the minority being excluded from board meetings, management decisions or access to the company's books; the company entering into related-party transactions on non-arm's-length terms that benefit the majority; the majority causing the company to buy assets from or sell assets to entities they control at unfair prices; and the diversion of business opportunities from the company to a related entity. What matters is not just the conduct itself but the effect on the minority's rights as a shareholder.

  • What is oppression of minority shareholders in Australia?

    It is conduct by majority shareholders, or by the company under majority control, that unfairly prejudices the minority's rights as a shareholder. The claim is brought under section 232 of the Corporations Act 2001 (Cth) and is available to minority shareholders in proprietary companies and public companies alike. The most common remedy is a buy-out order under section 233: either the majority is ordered to buy the minority's shares at a fair price, or (rarely) the minority is ordered to buy the majority. The Court can also order winding up on the just and equitable ground.

  • What is unfair prejudice against a shareholder?

    "Unfair prejudice" is one of the three categories of conduct that triggers section 232. It is conduct that unfairly disadvantages a shareholder in their capacity as a member, or in another capacity that flows from membership. The word "unfair" is critical: shareholders are not entitled to a particular outcome, but they are entitled not to be prejudiced by conduct that is not commercially justifiable or that departs from the reasonable expectations they had when they invested. Courts assess unfair prejudice by reference to what a reasonable shareholder in the applicant's position would consider unfair.

  • Is shareholder oppression a tort?

    No. Shareholder oppression is a statutory remedy under Part 2F.1 of the Corporations Act 2001 (Cth), not a tort. That means the claim is not for damages in the traditional sense. The Court's power under section 233 is to make orders regulating the conduct of the company's affairs, ordering a buy-out of shares, restraining or requiring certain conduct, appointing a receiver, or winding up the company. Damages-type orders can be made where compensation is warranted, but the primary remedies are structural.

  • What are the typical remedies provided by the Court for shareholder oppression?

    The Court has a broad range of remedies for shareholder oppression. Generally, those remedies include winding up the company or requiring the purchase of shares such that one shareholder buys, and one sells, with an appropriate reduction in the company's share capital.

  • What provisions in a shareholders' agreement can help resolve a dispute?

    Some key provisions in shareholder agreements that aid the dispute resolution process can include:

    • Dispute resolution clause. A dispute resolution clause may set out whether mediation is required in certain timeframes, what constitutes a dispute, and when the parties can proceed to litigation.
    • Right of refusal or offer clause. If you, or someone else, is exiting the company, this clause may require shares to be offered to existing shareholders first before any third-party purchasers.
    • Drag along and tag along rights. Where a third party wishes to purchase some (or all) of the company, a drag along clause may require a minority shareholder to sell shares. A tag along right may enable minority shareholders to sell alongside a majority shareholder.
    • Some shareholder agreements will include how to determine the sale and price of your shares.
  • How will the business be valued?

    Identifying the appropriate value for a party's shares can be a complex task, and there is no prescribed methodology for undertaking a valuation (and indeed the appropriate methodology will change depending on the nature of the company and even the tendency of a particular expert valuer).

    Ordinarily, the Court will appoint an expert to value the shares, with the trend being to appoint a single expert. Each party has the option of making submissions and the Court will ensure that the expert gets all the relevant information to carry out the valuation exercise.

  • What happens if both shareholders want to buy out the other?

    While there is surprisingly little authority about how a court would determine a dispute where both parties are wanting to be buyers, ordinarily, the majority holder will buy out the minority holder.

    In circumstances where shareholders are equal, it is more likely to follow that the party responsible for the oppression will buy out the shareholder who has been oppressed.

    This satisfies the objective of allowing release of the oppressed party from the company and recognises that an order providing for a minority to acquire the shares of a majority is rare.

    When determining the value, the Court will consider whether the value should be set so as to ensure that the shareholders responsible for the oppression do not benefit from the oppression. Other than adjustments that relate specifically to damage caused by the oppression, this is often carried out by ensuring there is no minority discount applied to the value for a minority shareholding.

  • Which Court will a shareholder oppression dispute be heard in?

    Oppression proceedings are brought before the Supreme Court or Federal Court.

  • How are oppression proceedings commenced in the Court?

    In 2018, the Supreme Court set out a new procedure for bringing oppression proceedings, aiming to fast track the process and save parties time and cost.

    Oppression proceedings are commenced in the Supreme Court by originating process and supporting affidavit of no more than three pages in length, which sets out a clear and succinct summary of the facts alleged to constitute the acts of oppression, the estimated value of the shares in the company, and exhibits a current ASIC search of the company.

    If initiating in the Federal Court, a document of up to five pages is allowed, which should summarise the important facts, the relief sought, the primary legal grounds, and the alleged harm.

  • How long does a shareholder oppression case take?

    Under the fast-track oppression procedure in the Supreme Court, matters can move from originating process to first substantive hearing within six to twelve months. Many oppression matters resolve at mediation within that window because the fast-track process forces both parties to a valuation and a buy-out proposal early. Matters that don't settle typically run for 12 to 24 months to final judgment. Aptum's project management framework gives you a forecast timeline at the pathways assessment stage and updates it as the matter progresses.

  • How much does a shareholder dispute cost to run?

    It depends on how contested the matter is and how far it needs to go. A defined oppression demand and buy-out negotiation can often be run for tens of thousands. A fully contested oppression matter through to a valuation hearing runs into six figures. Aptum discusses the cost-benefit at the diagnostic call and provides a stage-based cost forecast at the pathways assessment stage. Where the scope allows, fixed-price options are available for defined phases.

  • Can I sue my business partner in a partnership dispute?

    Yes. Partnership disputes are governed by the Partnership Act in each Australian state or territory and by the partnership agreement, if there is one. A partner can seek dissolution of the partnership, an account of partnership assets and profits, orders regarding partnership property, and damages for breach of the partnership agreement or breach of fiduciary duty. The typical outcome is one partner buying out the other, with the terms decided commercially or (rarely) by the Court.

  • Can a shareholder remove a director from an Australian company?

    Yes, in the right circumstances. The Corporations Act sets out different pathways depending on whether the company is proprietary or public and what the constitution says. Aptum has published a detailed guide on removing a director, including the resolutions required and the notice periods.
