It is a Tuesday morning and you cannot log into the company bank account. The password has been changed. Your business partner — the co-director and co-shareholder you have worked beside for years — has locked you out of the online systems, changed the locks on the office, and filed a form with ASIC removing you as a director without your knowledge or consent. You have no access to company records, no way to draw a wage, and no clear picture of what happens next.
What is at stake
When a business partner locks you out, the immediate shock is real, but the deeper problem is legal: your partner has almost certainly breached duties they owe to you and to the company. The question is how to enforce those duties without burning the business to the ground in the process.
The stakes go well beyond hurt feelings. You may be locked out of your own income. The business may lose customers if the dispute becomes public. Key supplier relationships can sour. If the company holds contracts that depend on both directors' signatures, the business may grind to a halt. And if your partner continues operating the business without you, they may make decisions that dig the company further into debt — debt you may be partly responsible for as a director.
The way forward depends on your business structure, the documents you have in place, and how far your partner is willing to engage. Court is rarely the fastest or cheapest answer, but you do have options.
Five steps to take when a business partner locks you out
Confirm your business structure and dig up the paperwork
Your first move is to figure out what rules govern your relationship. The answer depends on whether you operate through a company, a partnership, or a trust.
If you run a company, check whether you have:
- a shareholders agreement that sets out dispute resolution steps, buy-sell mechanisms, and how directors can be appointed or removed
- a company constitution that covers the same ground (some companies rely on the replaceable rules in the Corporations Act 2001 (Cth) instead)
- a copy of the current ASIC company extract showing who is recorded as a director and shareholder
If you run a partnership, look for:
- a written partnership agreement that states how disputes are handled and how the partnership can be dissolved
- any correspondence or conduct that shows what you agreed orally (verbal partnership agreements are still enforceable in Australia, though harder to prove)
If you cannot find a shareholders agreement or partnership agreement, do not assume you have no rights. The Corporations Act 2001 (Cth) provides a default framework for companies, and each state's Partnership Act implies duties into every partnership.
Document everything and secure what you can
Before you confront your partner, take stock of what you still control and gather evidence of what has happened.
What to collect:
- screenshots of any communications where your partner raised grievances or made threats
- emails or messages confirming you have been locked out of accounts
- bank statements, tax returns, and financial records you already have access to
- any version of the company constitution or shareholders agreement you can find, even an unsigned draft
- notes recording the dates and times of key events, including when you first noticed the lockout
Accounts you should try to secure:
- the company's ASIC online account (if you were the registered contact)
- the business bank accounts (contact the bank immediately if you suspect funds have been moved)
- your personal email records showing past business correspondence
- the company's domain registrar and hosting accounts
If your partner has filed a change of director details with ASIC without your consent, you can contact ASIC to query the lodgement and confirm whether the form was properly authorised. ASIC does not investigate disputes between directors, but it can confirm what is recorded on the public register.
Identify the duties your partner has likely breached
Australian law imposes clear duties on directors and partners. Understanding these duties helps you frame the dispute in legal terms — which is essential whether you are negotiating or seeking court orders.
For company directors — Part 2D.1 of the Corporations Act 2001 (Cth) sets out the core duties:
- s 180: a director must exercise their powers with the degree of care and diligence that a reasonable person would exercise. Locking out a co-director without proper process is hard to reconcile with this duty
- s 181: a director must act in good faith, in the best interests of the company, and for a proper purpose. Removing a co-director to gain personal control over company assets is a textbook breach
- s 182: a director must not improperly use their position to gain an advantage for themselves or cause detriment to the company. Using a director's access to change passwords and freeze out a co-director falls squarely within this section
For partners in a partnership — state Partnership Acts (for example the Partnership Act 1892 (NSW) or the Partnership Act 1958 (Vic)) impose duties including:
- acting with the utmost good faith towards each other
- providing full accounts of all partnership property and money
- not competing with the partnership or profiting personally from partnership opportunities without the other partner's consent
If your partner has locked you out of business premises, taken company funds for personal use, or filed documents with ASIC that misrepresent the company's directorship, they have almost certainly breached one or more of these duties.
Attempt negotiation and mediation before escalating
Litigation is expensive, slow, and unpredictable. For most small business disputes, a negotiated outcome is faster, cheaper, and more likely to preserve whatever value remains in the business.
Where to start:
- send a clear written request for access to company records and accounts. If your partner is still willing to talk, propose a meeting with agreed ground rules
- suggest engaging an independent valuer to assess the business — having a neutral valuation gives both parties a starting point for buyout discussions
- propose mediation. Mediation is a confidential process where a neutral third party helps you work through options. The mediator does not make a decision for you but can help cut through the emotion and identify outcomes that work for both sides
Even if you are not ready to negotiate a final split, you may be able to agree on interim steps — for example, restoring your access to bank accounts while the dispute is resolved, or agreeing not to make major business decisions without the other's consent.
Evaluate formal legal remedies as a last resort
If your partner refuses to engage, or if you have lost trust entirely, court action may be the only way forward. The main options available to you are:
- Oppression remedy (s 232 of the Corporations Act 2001 (Cth)) — if the conduct of the company's affairs is oppressive or unfairly prejudicial to you as a member, the court can make a wide range of orders, including requiring your partner to buy your shares at a fair price, or requiring them to sell their shares to you
- Winding up on just and equitable grounds (s 461 of the Corporations Act 2001 (Cth)) — if the relationship between directors has broken down to the point where the company cannot function, a court may order that the company be wound up. This is a drastic step that typically means the end of the business, but it may be the cleanest option if there is no workable relationship left
- Injunctions — in urgent cases, you can apply to the court for an order that restores your access to accounts and prevents your partner from dealing with company assets until the dispute is resolved
- Claims for breach of duty — you can sue your partner personally for losses caused by their breach of directors' or partners' duties, but this is complex and costly, and the court will usually direct you to mediation first anyway
The court system in Australia — particularly the Supreme Court and the Federal Court — will almost always refer you to mediation before allowing a trial. Going to court to get a mediation order is an expensive way to reach the negotiation table, which is why step 4 matters so much.
When to speak with a dispute resolution lawyer
A lawyer experienced in business disputes can help you at several points along this path, not just at breaking point. The earlier you get advice, the more options you preserve.
An Artificer Legal practitioner would start by reviewing your business structure and any governing documents. We would confirm what ASIC records show about your current director and shareholder status, and advise on any urgent steps needed to protect your position — such as freezing bank accounts or lodging a caveat against dealing with company assets.
If your partner is willing to negotiate, we can draft a formal letter setting out the legal grounds for your claim, propose a mediation framework, and work with you to develop a negotiation strategy that reflects your commercial priorities. If court action is unavoidable, we can prepare an application for urgent relief, such as an injunction to restore your access, and guide you through the winding up or oppression remedy process.
The goal is to resolve the dispute as cleanly and cost-effectively as possible, preserving the value of the business where that is realistic, and securing a clean exit where it is not.
The one thing to remember tomorrow
The most common mistake business owners make in this situation is treating it as a personal betrayal when it needs to be treated as a legal problem with a process. Your partner's conduct is almost certainly a breach of their legal duties. Document everything, understand your rights, and push for a structured negotiation or mediation before you spend money on litigation. The legal framework exists to protect you — but only if you use it at the right time and in the right order.
A shareholders agreement or partnership agreement is the single best protection against this situation, and most businesses do not have one. If you resolve this dispute and keep your business, or if you start a new venture, the best investment you can make is a properly drafted agreement that sets out what happens when the relationship breaks down — because it probably will not look like a Tuesday morning lockout. It will start with a disagreement that neither of you knows how to resolve.
