What Is A Fiduciary Duty?

If you’re running or growing a business in Australia, you’ll often hear the phrase “fiduciary duty.” It sounds technical, but the concept is simple: a fiduciary duty is a special obligation to act in someone else’s best interests.

Understanding when fiduciary duties arise, what they require, and how to manage them can save you from costly disputes and help you build trust with stakeholders. In this guide, we’ll break down fiduciary duties in plain English and show you practical steps to stay compliant.

What Does “Fiduciary Duty” Mean In Australia?

A fiduciary duty is a legal obligation that arises when one person or entity (the fiduciary) is entrusted to act for or on behalf of another (the principal or beneficiary) in a way that creates a relationship of trust and confidence.

In business, that trust comes with high standards. A fiduciary must put the other party’s interests ahead of their own, avoid conflicts, and not profit from the position unless clearly authorised.

Unlike ordinary commercial obligations, fiduciary duties are strict. Courts enforce them to protect vulnerable parties in relationships built on confidence-such as company directors and their company, partners to each other, agents for a principal, or trustees for beneficiaries.

Who Owes Fiduciary Duties (And To Whom)?

Fiduciary duties arise in common business relationships, including:

Company directors and officers to the company: Directors and officers control company assets and decisions, so they owe duties to act in the company’s best interests (not to individual shareholders).
Partners to each other: Partners manage a common venture and must be loyal and transparent with each other.
Agents to principals: Anyone authorised to act on another’s behalf (for example, a manager signing contracts for the company) owes duties of loyalty and good faith to that principal. Authority for agents to bind a company is also addressed in section 126 of the Corporations Act.
Trustees to beneficiaries: A trustee must manage trust assets solely for the beneficiaries’ benefit.

The key feature is reliance and vulnerability. If someone is relying on you to use power or discretion for their benefit, a fiduciary duty is likely to arise.

The Core Fiduciary Obligations You Should Know

While the scope varies with the relationship and circumstances, courts recognise several core fiduciary obligations. If you’re in a fiduciary position, these are your headline duties.

Duty To Act In The Best Interests Of The Principal

Decisions must be made for the benefit of the company, partnership, principal or beneficiaries. Personal considerations shouldn’t influence you.

Duty To Avoid Conflicts Of Interest And Duty

You must avoid situations where your personal interests, or duties to another person, conflict with your duty to the principal. If a conflict is unavoidable, you generally need informed consent from the principal before proceeding.

Duty Not To Make Undisclosed Profits Or Secret Commissions

You can’t use your position to make a personal gain unless fully disclosed and authorised. For example, a director shouldn’t take a business opportunity that rightly belongs to the company.

Duty Of Confidentiality

Information obtained through the fiduciary relationship must be kept confidential and used only for the principal’s purposes, unless you have clear permission to do otherwise.

Duty To Act In Good Faith

Fiduciaries must act honestly and loyally, exercising powers for proper purposes. Improper motives or collateral purposes can amount to a breach.

These fiduciary obligations often sit alongside other legal and contractual duties-for example, statutory directors’ duties under the Corporations Act 2001 (Cth) and the terms of a contract such as a service agreement or deed.

Company Directors: Fiduciary Duties And The Corporations Act

In Australia, company directors and officers owe both fiduciary duties at general law and statutory duties under the Corporations Act. The two sets of obligations overlap and reinforce each other.

Fiduciary Duties Of Directors

Loyalty to the company: Directors must act for the benefit of the company as a whole, not for personal advantage or the interests of a particular shareholder.
No conflict and no unauthorised profits: Directors should avoid conflicts and must disclose material personal interests; they cannot exploit corporate opportunities for themselves without proper approval.
Confidentiality: Sensitive information gained through the role can’t be misused or shared without authority.

Statutory Duties Under The Corporations Act

These include duties of care and diligence, good faith and proper purpose, and duties not to improperly use position or information. The duty of care and diligence is informed by the business judgment rule, which can protect directors who make informed, rational decisions in good faith for a proper purpose.

Governance Documents And Contracts Help In Practice

Good governance reduces the risk of breaches and misunderstandings. Many businesses adopt a Shareholders Agreement and a Directors Service Agreement to clarify decision-making, related party transactions, disclosure processes and approval thresholds. This clarity supports directors to meet their duties day-to-day and demonstrates a culture of compliance.

Managing Conflicts, Confidentiality And Contracts

Fiduciary duties are strict, but there are practical tools you can adopt to manage risk and operate confidently.

Identify And Disclose Conflicts Early

Create a simple internal process to declare interests, record decisions and obtain approvals from disinterested decision-makers where required. A documented approach helps you show conflicts were recognised and managed properly.

Adopt Clear Policies

For growing teams and boards, a written Conflict of Interest Policy sets expectations around disclosure, abstaining from votes, and how the business will handle related party dealings.

Use The Right Agreements

Director/Officer agreements: A tailored Directors Service Agreement can spell out confidentiality, conflicts, and IP ownership obligations in plain terms.
Confidentiality protections: When sharing sensitive information with third parties, a Non-Disclosure Agreement helps preserve confidentiality and reduces the risk of misuse.
Decision-making authority: Be clear about who can bind the company, and in what circumstances-this is aligned with how agency and authority work under section 126 of the Corporations Act.
Founders and investors: If you have multiple founders or external investors, your Shareholders Agreement can include related party transaction rules, approval thresholds and information rights that reduce conflict.

Practical Tips To Stay Onside

Document conflicts and approvals in board minutes and keep registers up to date.
When in doubt, step back from decisions that involve your personal interest and let independent decision-makers handle it.
Ensure commercial opportunities brought to you as a director are first considered by the company before you consider them personally.
Refresh board and leadership training on fiduciary and statutory duties, especially for new appointees.

Breach Of Fiduciary Duty: Remedies And Next Steps

If a fiduciary duty is breached, Australian courts can grant powerful remedies. These aim to reverse the wrongful gain and protect the principal.

Common Remedies

Account of profits: The fiduciary must hand over profits made from the breach.
Compensation (equitable compensation): To make up for loss caused by the breach.
Injunctions: To stop ongoing or threatened breaches (for example, using confidential information).
Constructive trust: Over assets obtained through the breach, treating them as held for the principal.

What To Do If You Suspect A Breach

Act quickly. Early steps might include preserving evidence, restricting access to systems, seeking interim undertakings, and getting legal advice on urgent injunctive relief.

Many disputes resolve without court. Where appropriate, parties formalise outcomes using a carefully drafted settlement instrument-often a Deed of Release and Settlement-to finalise obligations and reduce the risk of further claims.

Proactive Prevention Is Best

Most fiduciary disputes can be avoided by combining sound governance, clear contracts and consistent documentation. For directors, understanding the guardrails-such as the duty to act for proper purposes and the scope of the business judgment rule-helps you make robust decisions with confidence.
