Complex Property Division
Navigating Complex Property Division in Divorce:
What You Should Know and How the Courts Approach It
Splitting property after a relationship breakdown can be daunting—especially when the asset pool includes intricate holdings like businesses, overseas properties, trusts, or significant debt. Gaining clarity on how Australian courts handle these complexities is one of your best tools. This in-depth overview outlines the current legal approach, illustrates landmark rulings, and shares real-world examples to help you navigate the process confidently.
The Legal Structure: Australia’s Codified Four-Step Test (Post-June 10, 2025)
For married couples, Section 79 of the Family Law Act 1975 (Cth) applies, while de facto partners rely on Section 90SM. As of 10 June 2025, the legislation introduced a codified four-step pathway that all courts must follow:
- Clarify legal and equitable rights to property and debts.
- Evaluate contributions—whether monetary, non-financial (like parenting), or where family violence played a role.
- Take into account the parties’ present and likely future positions (e.g. health, caregiving roles, earning ability, and any disadvantages).
- Determine whether the final split is just and equitable.
A new addition to the law? Pets. Courts are now permitted to issue property orders concerning companion animals. This structure offers a more predictable, transparent process. Disclosure requirements, timing of contributions, and post-separation needs now carry greater weight.
Why Some Property Settlements Are Especially Complicated
Property divisions become more legally and financially involved when you’re dealing with:
- Company shares or business operations
- Offshore holdings or global trusts
- Trusts that are discretionary or family-based
- Major debt entanglements
- Reckless spending or asset dissipation before separation
In such matters, courts require accurate valuations, detailed tracing of who contributed what and when, and clear disclosure of asset control. Expert reports, forensic accountants, and full documentation become indispensable.
Legal Precedents That Reveal the Nuance of Complex Cases
- Norbis v Norbis (1986): The High Court ruled against formulaic methods. Judges must choose between a global or item-by-item approach depending on fairness.
- Muschinski v Dodds (1985): A constructive trust was imposed to protect a partner’s investment when formal ownership didn’t reflect true contribution.
- Kennon v Spry (2008): Trusts may be treated as property if one party controls them—otherwise, they may only count as financial resources.
- Kowaliw v Kowaliw (1981): The case confirmed that squandering shared assets can influence the final property division.
- Stanford v Stanford (2012): Regardless of how unequal the contributions are, fairness—“just and equitable”—is the ultimate goal.
Real-Life Examples of Complex Settlements
Massive Asset Split Upheld:
In one publicised case, a high-net-worth individual was ordered to hand over luxury homes and multimillion-dollar payments. The case highlighted how carefully the court assesses intricate portfolios.
Asset Freeze Denied:
Another case involved a spouse attempting to freeze $450 million in alleged coercive holdings. The court ruled against the freeze, citing insufficient risk. This underscores how the burden of proof can shape outcomes.
These examples show that even high-stakes disputes must adhere to the same principles—fairness, full disclosure, and legal precedent.
How Courts Evaluate Complex Property Settlements
Full Inventory of Assets
You’re legally required to disclose all holdings—from real property and superannuation to foreign bank accounts and directorships. Concealing or undervaluing assets can result in penalties or altered settlements.
This includes interests held via entities like companies or trusts. You must also disclose inheritances and pre-relationship savings. Courts won’t necessarily exclude them, but they need full visibility to decide how to treat them. Failing to disclose can be considered an act of dishonesty, harming your case.
Contributions—Not Just About Money
Courts consider both direct financial outlays and indirect input—like raising children, maintaining the home, or helping grow a business. They will “look behind” legal structures to assess true contributions.
Say you supported a business while your ex took home the pay—courts may still allocate value to your unpaid labour. In complicated matters, expert reports can be used to trace business growth, property value appreciation, or the long-term impact of one party’s efforts.
All contributions across the entire relationship are relevant—not just at the time of separation.
Shinohara Ruling: No More “Add-Backs” for Wasted Assets
In Shinohara & Shinohara (2025), the court clarified that it won’t reinstate wasted or spent assets into the divisible pool. Instead, this conduct influences either contribution assessments or the final division.
This replaces the old add-back approach. If one party, for example, squanders money through gambling, the court may adjust the asset split to favour the other. Keeping transaction histories and detailed proof is now more important than ever.
Taking Future Needs Into Account
Courts must assess whether either party faces financial difficulty moving forward—due to caregiving duties, reduced work capacity, health needs, or dependent children.
Let’s say you are the primary carer for a child with special needs or you’ve given up career progression to support the family. The court may grant you a larger share of the asset pool to help offset your lower earning potential or long-term care obligations.
Superannuation differences, age, and employability also factor into the court’s decision.
What You Can Do to Strengthen Your Case
Build a Comprehensive Asset Record
List everything: properties, trust interests, digital assets, superannuation, businesses—even high-value items like art or crypto. Back it all up with paperwork.
Track any changes in value and make sure your documents (valuations, statements, titles) are current. If your ex controls an asset, your lawyer can request full disclosure or raise it during proceedings.
Track All Contributions
Collect documents for everything—from mortgage repayments and investments to childcare and home renovations. Dates and proof are vital.
Use photos, receipts, bank records, or even testimony from others to verify your contributions. Intangible roles like budgeting or caring for family members are often undervalued but just as important. Keep a timeline if possible, showing how your efforts aligned with asset growth.
Keep Tabs on Dissipated Assets
If money was lost, transferred, or misused, collect evidence—statements, emails, or receipts—to show exactly what happened and when.
Even though those assets won’t be “added back,” the court can still tilt the scales based on that behaviour. This includes hidden withdrawals, giving away property, or spending sprees. Documenting these events early strengthens your position.
Get Independent Valuations for Complex Property
For anything beyond a simple asset—like a business, investment portfolio, or international property—professional valuations are critical.
Don’t rely on your ex’s accountant or an old tax return. Courts prefer objective, expert opinions from qualified valuers or forensic specialists. These can help you challenge lowball offers or inflated liabilities and give you leverage in negotiations.
Prepare for Your Future Financial Needs
Assemble evidence to show foreseeable expenses—healthcare, schooling, limited earning ability, or special needs care.
This might include medical records, letters from employers, childcare costs, or income statements. These details help the court shape a fair outcome based not just on the past—but what lies ahead.
Consider Alternative Dispute Resolution (ADR)
Complex cases don’t always have to go to trial. Mediation or collaborative family law can lead to more flexible and less combative solutions.
A skilled mediator can help both parties reach terms that court processes might overlook. ADR also tends to cost less and can be better for ongoing co-parenting relationships. Even if you don’t resolve everything, agreeing on some points can simplify the remainder of the legal process.
The Final Check: Is It Fair?
The outcome must pass the test of being “just and equitable.” The court has wide discretion and may move far from a 50/50 split if fairness calls for it.
For instance, if one party brought in significant wealth at the start of the relationship that remained separate, they may be awarded a larger share. On the flip side, someone who compromised their earning ability for the family’s benefit may receive more. The key is holistic fairness—not a simple mathematical formula.
