De Facto Director: Meaning Under the Corporations Act and Key Risks

When you’re building a startup or running a small business, it’s common for roles to blur.

You might have an investor who “just helps out”, a founder who stepped back from the board but still calls the shots, or a senior employee who negotiates major deals without much oversight. It can feel practical (and even necessary) when you’re moving fast.

But under Australian law, what you do can matter more than what your title says.

That’s where the concept of a de facto director comes in. Even if someone is not formally appointed as a director with ASIC, a court may still treat them as one if they act like one - and that can bring serious legal consequences for them and your business.

Below, we’ll walk you through what a de facto director is, how the Corporations Act applies, common risk scenarios for startups and small businesses, and practical steps you can take to protect your company as you grow.

What Is A De Facto Director (In Plain English)?

A de facto director is someone who:

• is not formally appointed as a director (for example, not listed with ASIC), but
• acts in the position of a director in practice, in a way that goes beyond simply giving advice or performing their usual role.

In other words, if someone is effectively performing the role of a director - making high-level decisions, representing the company, and controlling key business affairs - they may be treated as a director even without the official title.

This is especially important for startups and small businesses, because it’s common to rely on informal arrangements early on. But informality can create hidden exposure.

Why Does It Matter If Someone Is A De Facto Director?

Because directors have legal duties and can face personal liability if things go wrong.

That means someone who is “unofficially” acting as a director may still end up responsible for:

• director duties under the Corporations Act
• potential civil penalties and compensation claims
• insolvent trading risk (particularly if the company incurs debts while insolvent and the relevant legal tests are met)
• broader governance and compliance obligations

From a business-owner perspective, it also matters because unclear decision-making lines can:

• increase the risk of internal disputes
• cause confusion with banks, investors, and suppliers
• make it harder to prove who approved what (and when)

De Facto Director Under The Corporations Act: The Legal Concept

When people search for “de facto director” under the Corporations Act, they’re usually trying to understand whether the law really can treat someone as a director without an official appointment.

Yes - the Corporations Act recognises that someone can be a director based on their conduct, not just paperwork.

In particular, the definition of “director” in section 9 of the Corporations Act is broad enough to capture a person who is not validly appointed, but who acts in the position of a director (often referred to as a de facto director).

While the wording and interpretation can be technical, the key point for business owners is this:

If someone acts in the position of a director, they may be treated as a director.

Whether someone is a de facto director is ultimately a fact-specific question, usually determined by a court by looking at what the person actually did in the business and how the company operated in practice.

De Facto Director vs Shadow Director (Quick Comparison)

These two concepts often get mixed up, and both can create risk for your business.

• De facto director: someone who acts as a director in practice (they step into the role).
• Shadow director: someone whose instructions or wishes the formal directors are accustomed to follow (they control from behind the scenes).

In real life, the same person can sometimes look like both - for example, an influential founder who is not appointed, but attends “board-level” meetings, drives strategy, and the appointed directors routinely follow their lead.

Directors Are Not The Same As Shareholders

A lot of governance confusion starts with mixing up ownership and management.

Shareholders own the company (in a broad sense), but directors manage the company and make high-level decisions. If you’re unsure where the line sits, it’s worth getting clear on the distinction between a Director vs Shareholder.

This matters because a shareholder who starts behaving like management (approving deals, directing staff, controlling strategy) can unintentionally drift into de facto director territory.

Common De Facto Director Scenarios For Startups And Small Businesses

De facto director risk usually doesn’t come from bad intentions. It often comes from a fast-moving business where people are wearing multiple hats.

Here are some common scenarios we see in Australian startups and small businesses.

1. A Founder “Steps Off The Board” But Still Runs The Business

This is very common. A founder resigns as a formal director (for personal, strategic, or investor reasons), but continues to:

• approve major spending
• hire and fire senior staff
• negotiate key contracts
• set company strategy
• represent the company externally as “the boss”

If the founder still functions as a director in substance, the resignation may not fully protect them from director duties and liability.

2. An Investor Or Advisor Becomes Too Hands-On

Advisors and investors can add huge value, especially early on.

But there’s a line between:

• advice (which directors can choose to accept or reject), and
• direction/control (where the business effectively operates according to that person’s instructions).

A risk sign is when the appointed directors are “rubber-stamping” decisions made by someone who is not formally a director.

3. A Senior Employee Operates Like An Executive Director

Some businesses rely heavily on a general manager, operations lead, or head of sales who has wide authority. That can be completely legitimate.

The issue arises when the employee is effectively governing the business - for example, making strategic decisions that should be reserved for directors, or holding themselves out as part of the “company leadership” with director-like authority.

This can be especially tricky where delegations are not clearly documented.

4. Someone Signs And Negotiates Major Deals As If They Are “The Company”

Authority to sign is one indicator a court may consider when assessing control and function.

If a person regularly signs significant agreements, gives binding commitments, or negotiates major commercial terms with little director oversight, that conduct may be relevant to whether they were acting in the position of a director (depending on the full circumstances).

For companies, it’s also important to understand the formal signing pathways, including signing under section 127 of the Corporations Act, which is a common execution method for company documents.

5. Informal “Board Meetings” Where Non-Directors Lead Decisions

Startups often have informal leadership meetings. That’s not a problem by itself.

The risk is when the structure looks and operates like a board meeting, but the real decision-maker isn’t an appointed director. If meeting minutes (or even emails and Slack messages) show that a particular person consistently drives high-level resolutions, that can become evidence relevant to an allegation they were acting as a director.

What Are The Legal Risks If Someone Is A De Facto Director?

If someone is treated as a de facto director, the consequences can be serious - and not just on paper.

From a practical business standpoint, the biggest risk is that things can “work fine” until there’s a dispute, a failed raise, a regulatory issue, or financial stress. That’s when the company’s decision-making history gets examined closely.

1. Personal Liability For Director Duties

Directors have duties under the Corporations Act and under general law. In plain terms, directors must act properly, in the company’s interests, and with appropriate care.

If a person is found to be a de facto director, they may be exposed to the same standards and consequences as appointed directors.

2. Greater Insolvency And “Who Knew What” Scrutiny

When a company faces financial distress, the focus often turns to:

• who was really making decisions
• when they knew (or should have known) about cashflow problems
• what steps they took to protect creditors

Depending on the circumstances, this can include insolvent trading issues under the Corporations Act (for example, the rules in section 588G and related provisions), as well as potential claims by a liquidator.

Even if your business is healthy now, it’s worth setting up your governance properly so your future self isn’t stuck trying to reconstruct who approved what.

3. Disputes Between Founders, Investors, And Management

Unclear roles create friction. If expectations aren’t documented, you can end up with:

• power struggles between founders and investors
• confusion about who can hire/fire or approve spending
• arguments about whether a decision was “authorised”

This is one reason many startups put clear rules in place early with a Shareholders Agreement, so decision-making and reserved matters are properly documented.

4. Contract And Authority Problems

If someone without clear authority signs or commits the business to something, you can end up dealing with:

• supplier or customer disputes about whether the contract is binding
• internal conflicts about who approved the deal
• reputational issues with counterparties

This doesn’t just create legal risk - it creates operational chaos.

5. Insurance And Governance Gaps

Many businesses assume they can “sort it out later” if anything goes wrong.

But governance issues can impact:

• your ability to demonstrate proper approvals and oversight
• director and officer insurance (where applicable)
• investor confidence during due diligence

It’s much easier to fix this before problems arise than after.

How To Reduce De Facto Director Risk (Practical Steps For Business Owners)

If you’re a founder or small business owner, you don’t need to become a corporate lawyer to manage this risk - but you do need to create clear boundaries around decision-making.

Here are practical ways to reduce the chance that someone becomes (or is alleged to be) a de facto director.

1. Clearly Define Roles And Decision-Making Authority

Start with clarity:

• Who are the appointed directors?
• What decisions are reserved for the board?
• What decisions can management make day-to-day?
• Who has authority to sign contracts, and up to what limits?

For companies, these rules often sit within (or are supported by) a Company Constitution and your internal governance processes.

2. Be Careful With “Holding Out” (Titles, Email Signatures, Public Statements)

How someone is presented externally can matter.

It’s worth checking:

• LinkedIn titles (e.g. “Director” when they’re not appointed)
• email signatures
• website team pages
• introductions to suppliers and investors

If someone is not a director, avoid describing them in a way that implies they are part of the board or top governing body (unless they actually are).

3. Use Proper Approvals And Document Them

When key decisions are made, record them appropriately.

For example, if you’re a small company with a single director, you may rely on written resolutions. Getting the process right can help reduce uncertainty later - and it’s worth understanding how a sole director resolution works in practice.

Even if your business is moving quickly, good documentation is one of the simplest ways to show who actually made the director-level decisions.

4. Keep Advisors As Advisors (Not Decision-Makers)

It’s completely fine (and often smart) to involve mentors, investors and advisors in strategy.

But you should avoid a setup where:

• the directors feel they must follow the advisor’s instructions
• the advisor approves budgets, hiring, or contracts
• the advisor is effectively managing staff

A helpful way to manage this is to document the relationship properly - for example, clearly stating scope, boundaries, and reporting lines in an engagement arrangement. (This is particularly useful when the advisor is doing hands-on consulting work.)

5. Make Sure “Authority To Act” Is Actually Authority

Sometimes you do want a non-director to negotiate or sign on behalf of the company (for example, a head of operations managing supplier agreements).

That’s not automatically a problem - but it should be clearly structured.

Where someone is acting on behalf of the company, it helps to understand the law of agency principles, because “authority” can be express, implied, or even assumed based on how the company behaves over time.

Practically, you can reduce risk by setting written delegations, contract limits, and approval workflows.
