Introduction
Q1: Is my property settlement always calculated as a percentage?
A: No. Australian courts have the discretion to assess contributions as a fixed dollar amount rather than a percentage, especially when the asset pool is very large. The choice of method can shift the outcome by millions of dollars. Reference: Carmel-Fevia & Fevia (No. 3) [2012] FamCA 631
Q2: Does being a homemaker mean I automatically get less in a high-value divorce?
A: Not necessarily, but the way the court measures your contribution matters enormously. In very large pools, the court may value your homemaking and parenting in dollar terms rather than as a share of the total wealth. The size of the pool does not define the quality of your contribution. Reference: Zha & Wun (No 2) [2025] FedCFamC1A 101
Q3: Will the court always split everything 50/50 in a long marriage?
A: No. A long marriage does not guarantee an equal split. But when both parties contributed significantly over decades, the court must explain why any departure from equality is justified in dollar terms, not just in percentage terms. Reference: Fields & Smith [2015] FamCAFC 57
Why Do Courts Sometimes Reject Percentage Splits in Property Settlements?
When an asset pool reaches into the hundreds of millions, percentages can become misleading. A single percentage point in a $435 million pool equals $4.34 million. In a $565 million pool, it equals $5.66 million. Small shifts in percentage produce enormous swings in real money, and courts have recognised that this distortion can lead to unjust results.
The core problem is this: a homemaker's day-to-day contribution does not change because the other spouse happens to be extremely wealthy. Cooking meals, raising children, and managing a household require the same effort whether the family's net worth is $1 million or $500 million. When courts express contributions as percentages of a massive pool, they risk attaching a dollar value to homemaking that bears no relationship to what the person actually did.
The parties began their relationship in 2002. The husband was already a very wealthy man, serving as chairman of a commercial group of companies. He brought approximately $364 million into the relationship, representing about 83% of the eventual $435 million net asset pool. They married and had two children together. The wife also provided significant care for three of the husband's children from previous marriages. A financial agreement between the parties was set aside by the court prior to the final hearing.
The wife's contributions were primarily as a homemaker and parent across a six-year marriage. She made minimal direct financial contributions but was credited for her role during the period when the pool grew by approximately $66 million. The husband argued that any percentage-based assessment would massively overstate the dollar value of the wife's domestic contributions.
Cronin J agreed. The judge found that the extraordinary combination of extreme wealth and a relatively short marriage made percentage-based reasoning unsuitable. If the wife received even 5% of the total pool, that would be $21.75 million. The question was whether that figure genuinely reflected the value of what she contributed, or whether it was simply an artefact of the pool's size.
Outcome: The court awarded the wife $20 million in total. This comprised $10 million for her contributions (reflecting approximately 15% of the $66 million increase during the marriage) and an additional $10 million as a section 75(2) adjustment for her ongoing parenting role and the lifestyle expectations created by the marriage. A $500,000 deduction was applied for a prior part-payment.
"The use of percentages obscures what the Court is really asked to do which is to evaluate and give a dollar figure to what is an award or acknowledgement for the things done (rather than things achieved) by the contribution."
This distinction between things done and things achieved is central to the dollar-amount approach. A percentage rewards achievement (you get a share of the total result). A dollar amount rewards effort (you get paid for what you actually did). Cronin J argued that the court's job is the latter, not the former.
"Whether that [contribution] was made in a huge pool or in a small pool of assets, the contribution was just the same. The size of the pool cannot affect the fact that it was made."
How Do Courts Calculate Contributions as a Dollar Amount?
When a court decides to use the dollar-amount approach, it does not simply pick a number out of thin air. The judge works through the same statutory framework under section 79 of the Family Law Act 1975, identifying and weighing each party's financial and non-financial contributions. The difference is in how the result is expressed: instead of saying one party contributed 5% and the other 95%, the court assigns a specific dollar figure to the lesser contributor's share.
This approach has a practical advantage in cases where one party's financial contributions overwhelm the other's. In a $500 million pool where one spouse brought in almost everything, asking the court to assess the homemaker's contribution as a percentage forces an artificial exercise. Is it 3%? 5%? 8%? Each percentage point represents millions of dollars, and the differences feel arbitrary. A dollar-amount assessment lets the court focus on what the homemaker actually did and what that is worth, independent of the pool's total size.
The parties had a childless marriage lasting 7 years and 3 months. The net asset pool was found to be at least $565,988,500, with the largest single component being the husband's interest in a company called AB Ltd, valued at $493,638,785. The husband had initially claimed the pool was worth only about $50 million and denied any interest in AB Ltd. The court found he had engaged in a process of obfuscation regarding these assets.
The husband's financial contributions dwarfed those of the wife. He introduced AB Ltd and claimed initial contributions of $16.5 million. The wife conceded she had made minimal financial contributions. Nevertheless, the primary judge conducted what the Full Court described as a painstaking identification of the wife's various non-financial contributions across the marriage.
On appeal, the husband argued that the primary judge erred by not expressing the wife's contributions as a percentage of the pool. The Full Court rejected this argument decisively, holding that the Family Law Act imposes no obligation to use percentages. Given the great magnitude of the pool and the wife's own acknowledgment that her financial contributions were minimal, the judge was entitled to express the result as a fixed sum.
Outcome: The husband was ordered to pay the wife $9,744,000, bringing her total retention to $19.8 million. The Full Court held that the inclusion of the massive AB Ltd asset in the pool significantly addressed the wife's claims about non-disclosure, allowing the court to make a just and equitable order.
"The Act did not impose upon the primary judge an obligation to assess the wife's contributions as a percentage or fraction of a pool to which she conceded having made minimal financial contributions."
"The size of the pool did not define the nature and quality of the wife's contributions toward it."
The Zha & Wun decision is significant because it came from the Full Court in 2025, confirming that the dollar-amount approach established in Carmel-Fevia remains good law more than a decade later.
When Do Courts Still Use Percentage Splits for Property Settlement?
The dollar-amount approach is not the default. Most property settlements in Australia still use percentages, and for good reason. When both parties have made substantial contributions over a long relationship, percentages provide a natural framework for comparison. The dollar-amount method tends to emerge in a specific pattern: very large pools combined with relatively short marriages where one party's financial dominance is overwhelming.
In longer marriages where both spouses contributed significantly, courts have consistently used percentage-based assessments. But even then, the court must cross-check the percentage result against its dollar value to make sure the outcome makes sense.
The parties lived together for approximately 16 years, including 2 years of cohabitation and 14 years of marriage, and had three children together, aged 17, 15, and 6 at the time of the hearing. The husband, who also had two adult children from a previous marriage, had brought $5.66 million in net assets into the relationship and was the primary breadwinner throughout. The net asset pool totalled $13 million, while the wife had not been in paid employment, acting as the primary parent and homemaker for the entire relationship.
The husband sought an 80/20 split in his favour, arguing that his initial contributions and ongoing financial role justified keeping the vast majority of the pool. Loughnan J rejected this, noting that an 80/20 split would produce a $7.8 million gap between the parties, a result that was outside the legitimate range of discretion for a 16-year relationship with three children.
Instead, the judge used a percentage approach but explicitly tested it against dollar values. A 65/35 split produced a gap of approximately $3.9 million, which the judge considered appropriate given the husband's significant initial contributions balanced against the wife's 16 years of homemaking and parenting. An additional 2.5% section 75(2) adjustment ($323,636) was awarded to the wife, recognising that she was 23 years younger than the husband, had no formal qualifications, and remained the primary carer for the children.
Outcome: The court ordered a 65/35 split in favour of the husband for contributions, adjusted to approximately 62.5/37.5 after the section 75(2) adjustment. The dollar-effect cross-check was the tool that prevented an extreme result.
"This is not a mathematical exercise but it is appropriate to note the dollar effect of possible findings."
The Garwin approach is a middle path. The court used percentages as its primary tool but treated the dollar conversion as a reality check. If the dollar gap between the parties looks unreasonable for the length and nature of the relationship, the percentage needs to be adjusted.
The Full Court in Fields & Smith [2015] FamCAFC 57 took this further. In a 29-year marriage with a $32-39 million pool, the trial judge had ordered a 60/40 split. The Full Court overturned this, finding that the judge failed to explain why a roughly $8 million gap was justified in a nearly three-decade partnership where both parties contributed substantially. The Full Court ordered 50/50 instead, emphasising that percentage-based reasoning must always be tested by examining what the percentages mean in dollar terms.
"The court's reasoning process and the ultimate result... can be better illuminated by reference to the dollar value of a result which is, almost invariably, expressed in percentage terms."
What Determines Whether Your Property Settlement Uses Dollars or Percentages?
The choice between methods depends on three factors working together: the size of the asset pool, the length of the relationship, and the balance of contributions between the parties.
| Factor | Carmel-Fevia & Fevia (No. 3) [2012] | Zha & Wun (No 2) [2025] | Garwin [2012] | Fields & Smith [2015] |
|---|---|---|---|---|
| Asset pool | $435 million | $565 million | $13 million | $32-39 million |
| Relationship length | 6 years | 7 years | 16 years | 29 years |
| Children | 2 (plus 3 stepchildren) | None | 3 | 3 |
| One party's financial dominance | Extreme (83% brought in by husband) | Extreme (almost all from husband) | Significant ($5.66M initial) | Moderate (built together) |
| Approach used | Dollar amount | Fixed sum | Percentage with dollar cross-check | Percentage |
| Homemaker's share | Not expressed as % | Not expressed as % | 37.5% | 50% |
| Homemaker's dollar amount | $20 million | $19.8 million | ~$4.875 million | ~$16-19.5 million |
These four cases reveal a clear pattern: when the pool is enormous and the marriage is short with one party dominating financial contributions, courts tend to use dollars. When the marriage is long and both parties contributed substantially, courts use percentages but must explain the dollar gap.

Summary
The Family Law Act does not require courts to use percentages. Judges can express contributions as a dollar amount, a percentage, or both. There is no single mandated method.
Dollar-amount assessment typically applies to very large pools with short marriages. When one party brought in almost all the wealth and the relationship was brief, percentages can distort the value of homemaking contributions.
Percentage assessment remains the norm for longer marriages. When both parties contributed over decades, a percentage split provides a more natural framework for comparison.
Every percentage must survive a dollar cross-check. Even when courts use percentages, they should convert the result into dollars to ensure the gap between the parties is justified by the facts.
The size of the pool does not define the quality of your contribution. Raising children and running a household takes the same effort regardless of whether the family is worth $1 million or $500 million.
