In Australia, high-net-worth families often turn to legal structures that can protect, preserve, and manage family wealth across generations. One of the most sophisticated options available is the family office trust — a hybrid structure that combines the protective elements of a trust with the strategic oversight of a family office.
This article provides a legally focused exploration of how family office trusts function under Australian law, their tax implications, and when this model is best deployed.
What Is a Family Office Trust?
A family office trust is a legal structure that centralises the management of a family's financial and personal affairs under a trust arrangement. At its core, it is a trust — governed by a deed, managed by a trustee, and designed to benefit nominated beneficiaries.
What distinguishes a family office trust is the operational overlay: it operates like a private company with legal, financial, tax, and governance functions — often supported by professional advisors. It serves not just as an asset-holding entity, but as a governance vehicle for preserving intergenerational wealth, structuring investments, and facilitating succession planning. Families considering this model often want clarity on the distinction between a family office and a trust, as each serves different but complementary roles in wealth management.
Why Do Australian Families Use a Family Office Trust?
Australian families turn to a family office trust when they require a centralised, legally robust structure to manage intergenerational wealth, protect assets, and coordinate complex financial affairs.
The key reasons include:
- Asset Protection: The trust structure legally separates personal assets from family wealth, providing protection against creditors and litigation risks (subject to anti-avoidance rules and proper structuring).
- Tax Efficiency: Discretionary powers allow the trustee to distribute income across beneficiaries, often lowering the overall tax burden under Australian income tax law.
- Governance and Control: A family office trust facilitates formal decision-making structures, including family charters, advisory boards, and internal protocols — essential for managing disputes and aligning financial goals.
- Succession Planning: Unlike individual ownership or informal family arrangements, a trust can legally embed succession pathways and transfer control smoothly without triggering probate or family provision claims. Families often seek specialist advice at this stage, and understanding how to find a good family lawyer becomes critical to ensuring the trust deed, governance rules, and dispute resolution clauses are watertight and future-proof.
- Privacy and Confidentiality: Family office trusts operate privately, avoiding the disclosure obligations of public entities and preserving confidentiality over family assets and governance decisions.
In essence, families select this structure not just for its legal protections, but for the long-term control and strategic flexibility it affords across multiple generations.
Legal and Tax Considerations in Australia
Establishing a family office trust in Australia involves more than financial strategy — it requires full compliance with complex legal and tax frameworks. Understanding how the trust is regulated under Australian trust law, how income is assessed and distributed, and how capital gains are handled is crucial to ensuring the structure remains both effective and lawful. The following section outlines the key legal obligations and tax treatment issues Australian families must navigate when operating a family office trust.
Trust Law Foundations
A family office trust in Australia is established under state-based trust law, but must also comply with federal tax law and regulatory requirements. Key legal aspects include:
- Trust Deed: The core legal document that defines how the trust operates. It must be carefully drafted to include powers of the trustee, investment mandates, and distribution flexibility.
- Settlor and Trustee Roles: The settlor creates the trust; the trustee holds legal title and is responsible for administration. Trustees may be individuals or corporate entities.
- Fiduciary Duties: Trustees must act in good faith, avoid conflicts of interest, and act in the best interest of the beneficiaries.
Tax Implications
- Income Tax: Beneficiary income is taxed at their marginal tax rate. Income not distributed is taxed at the top marginal rate (47%).
- Capital Gains Tax (CGT): Applies on the disposal of trust-held assets, but CGT discounts may apply if the trust qualifies as a resident trust.
- Fringe Benefits Tax and Superannuation: May arise if the family office operates through a corporate trustee employing staff.
Given the complexity, legal and tax advice should be obtained before establishing the structure.
Governance and Succession Planning
A family office trust enables long-term strategic governance, which distinguishes it from traditional family trusts.
- Family Charters and Constitutions: These documents clarify family values, investment mandates, and behavioural expectations.
- Trustee Succession Planning: Legally documenting who will succeed the trustee is crucial to avoid disputes and maintain control.
- Dispute Resolution Mechanisms: Mediation clauses or family councils can be incorporated into the governance framework to manage future conflicts.
Legal clarity in these instruments reduces ambiguity and promotes stability across generations.
Advantages of a Family Office Trust
From a legal and operational perspective, the family office trust delivers several advantages:
- Asset Isolation from personal liability
- Strategic Income Distribution to optimise tax efficiency
- High Customisation through governance documentation
- Confidentiality, avoiding the need for public disclosure
- Clear Legal Ownership, via corporate trustees or layered holding structures
These benefits are particularly valuable in Australia, where asset protection and succession planning are core concerns for affluent families.
When to Use a Family Office Trust?
This structure is legally and financially viable when:
- The family holds $10 million AUD or more in assets
- Multiple family members are involved in decision-making
- There is a need for sophisticated investment structuring
- The family is operating multiple entities or property portfolios
- There's a focus on governance, legacy, and dispute prevention
For some families, a family office trust may also be viewed as an alternative to using an investment company, given its greater flexibility in governance, confidentiality, and succession planning.
FAQs: Legal Aspects of Family Office Trusts in Australia
A short legal explainer based on common high-intent queries:
What are the legal duties of a trustee?
Trustees owe fiduciary duties under Australian trust law, including loyalty, prudence, and acting in the best interests of the beneficiaries.
Are family office trusts regulated?
While there’s no special licence for a family office trust, it must comply with the Corporations Act 2001, the Taxation Administration Act, and relevant state-based trust legislation.
Can a family office trust own shares in a company?
Yes. The trust can hold business interests, shares, or controlling stakes in family-owned companies through its investment mandate.
How are disputes resolved in a family office trust?
Legal dispute resolution is ideally pre-empted through internal governance mechanisms. If needed, mediation or Supreme Court intervention may apply.
Can a family office trust donate to charity?
It can, but it must be legally structured to do so. Alternatively, a separate charitable trust or PAF (Private Ancillary Fund) may be more appropriate.
