Corporate Trustee Duties in Australia Explained

Many Australian small businesses trade through a trust with a company as trustee. It’s a popular structure for asset protection and flexibility - but it also creates a web of legal duties that you need to manage carefully.

If your company is the trustee of a family (discretionary) trust, unit trust or business trust, the people running that company carry duties under both trust law and the Corporations Act. Understanding those duties - and setting up simple systems to comply - can save you from personal liability, tax headaches and costly disputes later.

In this guide, we’ll unpack what a corporate trustee is, the key corporate trustee duties in Australia, how directors’ obligations fit in, and the practical steps you can take to stay compliant day-to-day.

What Is A Corporate Trustee (And Why Do Small Businesses Use One)?

A “corporate trustee” is simply a company that holds and manages assets on trust for beneficiaries. The trust itself isn’t a separate legal person - the trustee is the legal face that signs contracts, holds the bank account and runs the business on behalf of the trust.

Small businesses commonly use a trust-and-company structure because it can offer flexibility in distributing profits, potential tax efficiencies and a degree of asset protection. For example, you might operate your café through a family trust, with a company as trustee, and distribute profits to family members or a bucket company as appropriate.

It’s important to remember: the trust terms live in the trust deed, and the trustee (your company) must follow those terms strictly. The beneficiaries benefit from the trust assets and income, but they don’t own those assets directly.

If you’re weighing up a trust for your venture, it helps to understand how trusts fit into asset protection and tax planning, and whether you’ll use a discretionary trust or unit trust model. If you’ll hold equity in another company, consider whether holding shares through a trust makes sense for your goals.

What Duties Does A Corporate Trustee Owe?

A corporate trustee wears the trustee hat at all times when dealing with trust assets. Under Australian trust law (and the trust deed), core duties include:

• Act for the Benefit of Beneficiaries: Always act in the best interests of the beneficiaries and for a proper purpose authorised by the trust deed.
• Follow the Trust Deed: Strictly comply with the terms of the deed - distributions, investment powers, appointment/removal of trustees, and any limits on borrowing or guarantees.
• Avoid Conflicts: Don’t place yourself in a position where the trustee’s interests conflict with beneficiaries’ interests. If the trustee will benefit (e.g. via fees or related-party dealings), ensure the deed permits it and manage conflicts transparently.
• Not Profit from the Position: The trustee shouldn’t profit from its role unless the deed clearly allows remuneration or specific benefits.
• Act Prudently and With Due Care: Manage trust business and investments prudently, like a careful person would with their own affairs (taking into account any investment clauses in the deed and applicable trustee legislation).
• Keep Proper Accounts and Records: Maintain clear, separate records for the trust. Don’t mix trust money with the company’s or other trusts’ money.
• Distribute Income/Capital Properly: Make distributions strictly in line with the deed (and within required timeframes for tax purposes).

These are duties of the trustee (your company), but practically it’s the directors who make decisions. That’s where directors’ duties come in - you’re juggling two sets of obligations at once.

How Do Directors’ Duties Interact With Trustee Duties?

When a company acts as trustee, its directors must comply with both the Corporations Act and trust law. In practice, directors should:

• Act in Good Faith and for a Proper Purpose: Directors must act in the best interests of the company-as-trustee. Because the company’s purpose is to administer the trust for beneficiaries, that usually means aligning decisions with the trust deed and beneficiaries’ interests.
• Exercise Care and Diligence: Make informed decisions, document key resolutions, and get advice where needed (for example, on complex distributions or related-party transactions).
• Avoid Improper Use of Position or Information: Don’t misuse your role or confidential information for personal gain at the trust’s expense.
• Manage Conflicts: If a director (or their related entities) supplies goods/services to the trust, handle it at arm’s length and in line with the deed and company governance rules.

A common question is how “control” and beneficiary interests are viewed in corporate groups. If you’re structuring investments or subsidiaries under a trust, it’s worth understanding how control under the Corporations Act can affect your compliance and reporting obligations.

Practically, your governance framework should make it easy to comply. Clear roles, documented delegations, and robust minutes make a big difference when you’re balancing trustee and director responsibilities.

Practical Risks to Watch (Contracts, Bank Accounts, Indemnities)

Most issues with corporate trustees aren’t caused by a single catastrophic error. They arise from small process gaps - a missing capacity line on a contract, mixed bank accounts, or a distribution that doesn’t match the deed. Here are the big-ticket items to manage proactively.

1) Signing Contracts in the Right Capacity

When the trustee company enters contracts, make sure it’s crystal clear that you’re contracting “as trustee for ”. Use the full legal name of the company and trust, and include capacity wording in signatures and on invoices.

If you sign only in the company’s name without capacity wording, a counterparty could argue you contracted in the company’s own right. That can jeopardise your right of indemnity from trust assets and expose the company (and potentially you) to unnecessary risk.

Also make sure your execution process complies with section 127 for company signing, or set up an appropriate delegated authority policy for day-to-day contracts.

2) Keeping Trust Money Separate

Operate a dedicated trust bank account. Don’t pay personal or non-trust expenses from that account. Mixing funds (commingling) can breach trustee duties, complicate tax, and undermine asset protection. If the trustee incurs expenses on behalf of the trust, ensure they’re clearly documented and reimbursed appropriately.

3) Understanding the Trustee’s Right of Indemnity

Generally, the trustee is entitled to be indemnified out of trust assets for liabilities it properly incurs in administering the trust. This is critical - it’s how the trustee pays suppliers and creditors.

However, that right of indemnity can be limited or lost if you act outside power (ultra vires), breach the deed, or fail to keep proper records. If your indemnity is curtailed, the company may be on the hook from its own assets. That’s why it’s so important to operate strictly within the deed and document decisions properly.

4) Related-Party Dealings and Guarantees

It’s common for a lender to require director guarantees when funding a trust business. Before you sign, understand the consequences. A guarantee is a personal promise; it cuts through the trust’s asset protection if things go wrong.

If your structure relies on separation of risk, be cautious about personal guarantees and ensure any related-party supplies (e.g. services from a director’s other company) are on clear, arm’s length terms that the deed permits.

5) Distributions and Resolutions

Make distributions strictly according to the deed and by the required dates. Keep written resolutions that show who was made presently entitled and on what basis. Inconsistent or late distributions can create tax issues and expose the trustee to claims from unhappy beneficiaries or unit holders.

6) Record-Keeping and Minutes

Keep a robust minute book for the trustee company. Record key decisions: entering major contracts, approving distributions, appointing agents, adopting policies and authorising bank signatories. Good minutes are your first line of defence if a decision is later challenged.

Governance Documents and Structures That Help You Stay Compliant

A well-run trust business isn’t just about the trust deed. Put simple company governance in place so decisions are made properly and recorded. A few practical tools:

• Company Constitution: Ensure your trustee company’s Company Constitution supports how you operate - director decision-making, share classes, and any specific trustee-related provisions you need.
• Board Policies and Delegations: Adopt a delegations policy for who can sign what (and in which capacity), spending limits, and bank authorisations. This reduces the risk of someone contracting outside power.
• Resolutions and Registers: Maintain clear board resolutions for distributions, borrowing, guarantees and related-party transactions. Keep a register of conflicts.
• Deeds and Indemnities: Directors of a trustee company often seek a Deed of Access and Indemnity, and the company itself will rely on the trust deed’s indemnity. Understand what’s covered (and what isn’t) so you can fill any gaps with process or insurance.

If your corporate trustee is part of a broader group with other shareholders or unit holders, align the governance across the structure. Use a Shareholders Agreement for the trustee company, and a Unitholders Agreement for a unit trust vehicle if required. This avoids disputes over who decides distributions, who appoints directors, and how exits work.

Finally, check your deed and governance documents work together. If you’re relying on a specific power in the deed (for example, paying trustee fees or appointing a manager), make sure your company documents and board processes support that approach.

Setting Up and Using Deeds the Right Way

Trusts are created and changed by deed. When you update appointors, change trustees, vary distribution powers or document director protections, you’ll usually use a deed or deed poll. Deeds have stricter execution requirements than ordinary agreements, so it’s worth a quick refresher on the essentials.

• Use the Right Instrument: Many trust changes require a deed because the trust deed says so. Before acting, confirm the variation power exists and the correct parties are signing.
• Execute Correctly: Follow formalities and the company’s signing rules. Some documents can be signed electronically, but proceed carefully for deeds and check your jurisdictional rules and the document’s requirements.
• Keep Originals Safe: Store executed deeds securely and maintain a clear deed register so you can prove authority later.

If you’re unsure which instrument to use (agreement vs deed), or how to sign, it’s helpful to read a short refresher on what a Deed is and why it’s different from a standard contract.

Frequently Asked Questions About Corporate Trustee Duty

Does a corporate trustee have limited liability?

The company structure generally limits shareholder liability, but the trustee’s practical protection comes from its indemnity out of trust assets for properly incurred liabilities. If the trustee acts outside the deed or breaches duties, that indemnity can be lost. Also, guarantees can create personal exposure for directors or related entities.

Who owes duties - the trustee or the directors?

The trustee company owes trustee duties under the trust deed and trust law. The directors owe duties to the company under the Corporations Act and must ensure the company (in its trustee role) complies with the deed and acts properly for beneficiaries.

Can the trustee charge fees?

Only if the trust deed permits it (or beneficiaries consent where applicable). If the trustee or a related entity provides services to the trust, ensure the deed allows it and put documented, arm’s length terms in place.

What happens if the company trades both for the trust and on its own?

This is risky. Keep roles and bank accounts separate. If the trustee company must also contract in its own capacity, use strict capacity wording in documents and resolutions so liabilities and cashflows aren’t mixed.

How do these duties apply if the trust owns shares in an operating company?

The trustee must exercise shareholder rights in line with the trust deed and beneficiaries’ interests, while the directors of the operating company must act in that company’s best interests. Where structures get layered, be mindful of how influence and control under the Corporations Act may be assessed.

Key Legal Documents for Businesses Using Trusts

Every structure is different, but most corporate trustee arrangements benefit from a core suite of tailored documents:

• Trust Deed (and Variations): The foundation document. It sets trustee powers, distribution rules, conflict management and indemnities.
• Company Constitution: Your trustee company’s rulebook. A well-drafted Company Constitution supports smooth governance and clear director authority.
• Shareholders Agreement: If there’s more than one shareholder in the trustee company, a Shareholders Agreement handles decision-making, issuing shares, exits and disputes.
• Unitholders Agreement: For unit trusts, a Unitholders Agreement can supplement the trust deed on governance, distributions and transfers of units.
• Board Policies and Delegations: Practical tools for who can sign, bank mandates, conflicts and spending limits.
• Commercial Contracts: Clear customer terms, supplier agreements and any related-party contracts on arm’s length terms.
• Deeds (Access, Indemnity and Releases): A director-focused Deed of Access and Indemnity and other deed instruments you’ll use for trustee changes or important variations.

Not every business will need everything on day one, but it’s smart to prioritise the documents that control money flows, decision-making and signature authority. As you grow, round out the rest.

Key Takeaways

• A corporate trustee must follow the trust deed, act for beneficiaries, avoid conflicts, keep clean records and make distributions properly.
• Directors of the trustee company juggle dual obligations - company law duties and the trustee’s duties - so good governance and minutes matter.
• Day-to-day risks are practical: signing in the right capacity, keeping trust money separate, protecting the trustee’s indemnity and documenting distributions.
• Use simple governance tools - a strong Company Constitution, clear delegations and appropriate deeds - to make compliance the default.
• Align documents across your structure, including any Shareholders Agreement for the trustee company and Unitholders Agreement for a unit trust.
• If you’re unsure whether a change needs a deed or how to structure control and distributions, get tailored advice early to avoid costly fixes later.
