Fiduciary Relationship Examples Australian Business Owners Should Know

If you’re building a business in Australia, you’ll probably hear the phrase “fiduciary relationship” sooner than you expect - often when you’re appointing directors, bringing in investors, hiring key team members, or partnering with someone who will handle money or sensitive information.

For founders and small business owners, understanding fiduciary relationship examples isn’t just a legal “nice to have”. It can be the difference between running a business with clear accountability (and fewer disputes) versus dealing with messy conflicts, claims of misconduct, or arguments about who owed what duties to whom.

In this guide, we’ll break down what a fiduciary relationship is in practical terms, give you real-world fiduciary relationship examples that commonly come up for Australian SMEs, and explain how you can protect your business with the right structure, documents and processes.

What Is A Fiduciary Relationship (In Plain English)?

A fiduciary relationship is a relationship where one party is expected to act in the best interests of another party, because they have power, influence or control over something important (like money, property, decision-making, or confidential information).

In business, fiduciary relationships often arise when someone:

• has authority to make decisions on behalf of the business or another person,
• controls business assets or funds,
• has access to sensitive business information, or
• is trusted to act loyally (not for personal benefit) in certain dealings.

While the details can vary depending on the exact relationship, fiduciary duties typically include things like:

• Acting loyally (not putting personal interests ahead of the business/person they owe duties to)
• Avoiding conflicts of interest (or properly disclosing and managing them)
• Not misusing position or information
• Not making secret profits (for example, taking undisclosed commissions)
• Acting in good faith and for a proper purpose

One important point for founders: fiduciary duties can exist even if you never signed a contract describing them. They can arise because of the role someone holds (like a director) or the nature of the relationship (like an agent acting on your behalf).

Fiduciary Relationship Examples Australian Business Owners Actually Deal With

When people search for “fiduciary relationship examples”, they’re usually trying to work out whether a relationship in their business has a higher level of legal responsibility than a normal commercial arrangement.

Below are fiduciary relationship examples that regularly come up for Australian small businesses and founders.

1. Company Directors And The Company

If you run a company, directors are one of the clearest fiduciary relationship examples.

Directors are expected to act in the best interests of the company (not just the shareholders individually, and not themselves). This matters in everyday decisions like approving spending, signing contracts, entering partnerships, or deciding whether to raise capital.

Common risk areas we see in practice include:

• a director directing company work to a business they secretly own,
• a director using company opportunities for personal gain,
• decision-making where the director has a personal interest (and doesn’t disclose it), and
• poor record-keeping around decisions (which can create disputes later).

If you’re setting up (or cleaning up) your governance, having a Company Constitution can help clarify how decisions are made and what rules apply internally, especially if you have multiple directors or shareholders.

2. Partners In A Partnership

If you operate as a partnership, the relationship between partners is another common fiduciary relationship example.

Partners generally owe each other duties of loyalty and good faith in how the partnership business is run. In a practical sense, that can mean:

• not competing with the partnership business (unless agreed),
• not taking partnership opportunities for yourself,
• accounting properly for partnership money, and
• being transparent about conflicts.

Because partnership arrangements can become unclear quickly (especially if things are “handshake” based), it’s usually worth having a written Partnership Agreement that sets expectations about decision-making, profit share, roles, and what happens if someone wants to exit.

3. Agents Acting On Your Behalf (Including Brokers And Sales Agents)

Whenever you authorise someone to act on your behalf - for example, negotiating deals, signing documents, buying equipment, selling products, or engaging suppliers - you may be creating a fiduciary relationship.

This shows up in many SME situations, including:

• a sales agent negotiating contracts with your customers,
• a buyer’s agent sourcing a business or commercial site for you,
• a broker arranging finance or negotiating terms with lenders, or
• a consultant negotiating supplier pricing in your name.

Agents generally must act in your best interests within the scope of what you authorised them to do. Problems often arise when the scope is unclear (for example, “you can negotiate for us” without clear limits) or where the agent has incentives you don’t know about.

Even a simple written authority can reduce misunderstandings. In some cases, an letter of authority to act on behalf is a practical way to document what the person can and cannot do.

4. Employees In Positions Of Trust (Senior Employees, Finance Staff, Key Account Managers)

Not every employee is automatically a fiduciary in the same way a director is. In Australia, whether an employee owes fiduciary duties (or fiduciary-like obligations) is very fact-specific and tends to apply in more senior or highly trusted roles.

For founders, the higher risk roles tend to be people who can:

• authorise payments or access bank accounts,
• approve discounts, refunds or customer credits,
• access your customer list, pricing model or trade secrets,
• negotiate or sign contracts, or
• manage key customer relationships and goodwill.

This is why it’s important your key staff are on the right documents from day one, including an Employment Contract that clearly deals with duties, confidentiality, conflicts, and post-employment restraints (where appropriate).

5. Trustees And Beneficiaries (If You Use A Trust Structure)

Trusts are common in Australian business structures, including family trusts used to hold business assets or operate a business. A classic fiduciary relationship example is the relationship between a trustee and beneficiaries.

Trustees generally must act in the best interests of beneficiaries and comply with the trust deed. In a business context, this can impact:

• how distributions are decided (which may also have tax implications),
• how trust assets are used (for example, equipment, IP, cash), and
• whether decisions are properly authorised under the trust deed.

If you operate through (or alongside) a trust, it’s worth ensuring your agreements and asset ownership align with your structure - particularly where the company and the trust interact. You should also get tax and accounting advice on trust distributions and compliance.

6. Advisers Handling Your Money Or Making Decisions For You (In Specific Circumstances)

Many professional advisers (like accountants, bookkeepers, lawyers, and financial advisers) have professional obligations, and in some situations may also be found to owe fiduciary obligations. However, this is not automatic and depends on the circumstances - for example, whether they are acting as your agent, have authority to make decisions on your behalf, or control client money.

As a business owner, the key point is this: if someone is making decisions for you, or handling your money, you should treat it as a high-trust relationship and document the arrangement clearly (scope, reporting, approval limits, and accountability).

Why Fiduciary Duties Matter For Founders (Even When Everyone “Gets Along”)

Early-stage businesses often run on trust. That’s normal - and it’s part of what makes startups move fast.

But fiduciary duties matter most when something changes, like:

• a co-founder relationship breaks down,
• an investor comes in and expectations shift,
• a director resigns and starts a competing business,
• a senior employee leaves and takes key customers, or
• someone makes a decision that benefits them personally and harms the business.

In these moments, fiduciary obligations can affect:

• who “owns” a business opportunity (was it the company’s opportunity or someone’s personal opportunity?),
• whether a person needed to disclose a conflict,
• whether profits must be repaid (for example, undisclosed commissions),
• whether a person can be restrained from certain conduct, and
• what remedies are available if the business suffered loss.

Thinking about fiduciary relationship examples early is essentially a risk management exercise: you identify where trust exists in your business, and you put clear guardrails around it.

Common Red Flags: When A Fiduciary Relationship Can Create Risk In Your Business

It’s not “bad” to be in a fiduciary relationship - it’s common and often necessary. The risk is when a fiduciary relationship exists but you haven’t set expectations, boundaries, and documentation.

Here are common red flags we see with small businesses and founders:

Undocumented Authority

If someone can commit your business to contracts or spending, you want that authority defined and limited. Otherwise, you may be dealing with unauthorised commitments, disputes about approvals, or internal blame-shifting.

Conflicts Of Interest That Aren’t Disclosed

A conflict isn’t always fatal - but hiding one is where problems arise. For example, a director who owns a supplier, or a manager who receives kickbacks for choosing certain vendors.

“Side Hustles” That Overlap With The Business

It’s common for founders and key staff to have other projects. The issue is when those projects compete, or when someone uses your business’s confidential information or customer relationships to build their own venture.

Poor Record Keeping Around Decisions

When there’s a dispute, the question often becomes: “Why was this decision made, and was it made properly?” Minutes, written consents, and clear approvals can make a big difference.

Co-Founders Without Clear Rules

Founders may assume they’re “equal” or on the same page, but unless it’s written down, expectations can diverge quickly - especially around pay, ownership, and exit rights.

If you have multiple owners, a Shareholders Agreement can help set rules around decision-making, share transfers, deadlocks, and what happens if someone wants to leave.

How To Protect Your Business When Fiduciary Duties Exist

The goal isn’t to remove trust - it’s to make trust sustainable as your business grows.

Here are practical steps you can take to manage fiduciary risks in your business.

1. Get The Structure Right Early

Your business structure affects who owes duties to whom, and how decisions are made. For example, directors of companies have specific obligations and governance expectations that differ from partnerships.

If you’re not sure whether a sole trader, partnership, or company structure is right for you, it’s worth getting advice early. Fixing structure later can be time-consuming and expensive.

2. Use Clear, Written Agreements (Even If You’re Friends)

Many disputes happen when people rely on “we’ll figure it out later”. Written agreements help you avoid memory-based decision-making when things get stressful.

Depending on your business, this may include:

• founder/shareholder documentation (ownership, roles, exit rules),
• employment contracts for key team members,
• contractor agreements for key service providers, and
• authority documents for agents or representatives.

3. Set A Practical Conflict Of Interest Process

You don’t need a complex corporate system to manage conflicts - but you do need consistency.

A simple approach might include:

• requiring directors and senior staff to disclose conflicts in writing,
• keeping a basic conflict register, and
• documenting how the conflict was managed (for example, the person didn’t vote on the decision).

This is especially important if your business is growing and you’re taking on investors, because governance becomes part of how you build trust in the business.

4. Put Confidentiality And Information Protections In Place

A lot of fiduciary disputes revolve around information: customer lists, pricing, product roadmaps, supplier terms, and strategy.

For employees and contractors, confidentiality clauses should be clear and fit-for-purpose. For external discussions (like potential investors, collaborators, or suppliers), an NDA may be appropriate depending on the situation.

5. Don’t Forget Customer-Facing Compliance (It’s Part Of “Acting Properly”)

Fiduciary relationships often exist behind the scenes, but founders are still responsible for the public-facing legal obligations of the business.

For example, if you sell products or services to customers, you’ll need to comply with the Australian Consumer Law (ACL), including rules around refunds, consumer guarantees, advertising, and avoiding misleading conduct.

If your website or business collects personal information (like emails, payment details, delivery addresses, or enquiry forms), having a Privacy Policy is often a key part of building compliance into your operations.
