A high net worth divorce case involves property and estates that have a high monetary value. In the past two years, owing largely to the pandemic, there has been an exponential surge in divorce cases in Australia. Due to frequent lockdowns and the sudden shift in the dynamics of the household, many people have been forced to separate from one another.
A divorce case in itself can become very complicated. Lawyers have the responsibility to duly consider each party’s individual circumstances and to navigate through the divorce process with great diligence.
Divorce cases become particularly complicated when they involve high net worth individuals. A high net worth divorce is generally considered to involve a combined asset pool of $5 million or more, and the Australian Taxation Office categorises “wealthy individuals” as those with a net worth exceeding $5 million. In these cases, all the property owned by the couple has a significantly high monetary value — and divorces involving high net worth individuals entail considerably greater financial and legal complexity than standard separations.
In 2018, when Jeff Bezos and Mackenzie Bezos divorced, Mackenzie received 25 percent of Amazon’s shares as part of the settlement, amounting to more than $35 billion USD. This is one of the most famous examples of a high net worth divorce. Closer to home, Section 121 of the Family Law Act prohibits the publication of divorce proceedings where the parties are identifiable. Australia has had its own share of high-profile separations, including that of billionaire media mogul Rupert Murdoch.

Property Settlement in High Net Worth Divorce Cases
In the legal industry, property division is widely regarded as the most disputable stage in divorce proceedings. In Australia, a five-step approach as outlined in the Family Law Act 1975 is used to determine the division of assets following a divorce or separation. The property settlement process in high net worth divorces generally follows the same legal framework as other divorces, but it often takes considerably longer due to the complexity of the assets involved.
1. Identifying every asset and liability
These generally include property, savings, loans and mortgages. For high net worth divorce cases, there are many more assets and liabilities to consider, including stocks, investments, businesses, collections and intellectual property. The asset pool may also include real estate, superannuation, business interests, shares, and assets held in family trusts and self-managed superannuation funds.
2. Evaluating the existing division of assets
In certain cases, the involved parties will be satisfied with the existing division of assets. However, in high net worth divorce cases, there is almost always a need to adjust the division of assets to make it more equitable.
3. Assessing the contributions
Once the process to divide assets begins, lawyers gauge the contributions made by both parties to the total asset pool. Both financial and non-financial contributions are assessed. Financial contributions include income, whereas taking care of the home and children constitutes non-financial contributions.
It is important to note that the courts no longer recognise “special contributions” by high-income earners. In the landmark case of Hoffman v Hoffman, a husband appealed an equal division of a $10 million asset pool after a 36-year marriage, arguing that his entrepreneurial flair and special skills created the wealth. The court dismissed the appeal. Business success or investment growth does not automatically outweigh the contribution of a homemaker or parent.
4. Estimating future needs of both parties
Factors including the age of the spouse, their mental capacity and health, future earning capacity, and the custody of children are taken into account to estimate the future financial needs of both parties. High net worth divorces often involve significant disparities in income between the parties. One party may also seek substantial spousal maintenance based on financial need, particularly where the standard of living during the marriage was high. The pre-separation standard of living, while not a formal test, is a relevant consideration.
5. Ascertaining if proposed orders are equitable
The Family Court of Australia aims to ensure a fair and equitable division of assets, which does not necessarily mean a 50/50 split. The court checks that the proposed division of assets is fair and just, with the intent of creating certainty for the future for both parties.

Financial Disclosure and Hidden Assets in Australian Separations
Financial disclosure is a crucial part of financial separation, requiring each party to share all relevant information about their earnings, income, property and other assets. Parties in a high net worth divorce have a duty to disclose all assets and liabilities to ensure a fair and equitable outcome.
It is common, however, for parties in high net worth marriages to believe they are entitled to keep or hide certain assets because those assets are solely held in their name. This is not the case. Hidden assets can significantly complicate divorce proceedings, and the Family Court has broad powers to investigate and order full financial disclosure if one party attempts to conceal assets.
Critically, a failure to provide full and frank disclosure can mean that any property settlement reached is not “final”. Under Section 79A of the Family Law Act, the court can set aside an existing property settlement order if it is later discovered that one party misrepresented or failed to disclose assets. Under Section 106B, the court can also reverse asset transfers made to reduce or defeat the other party’s claim.
Engaging forensic accountants to trace hidden assets is common in high net worth divorce cases. These specialists can uncover undisclosed bank and brokerage accounts, undervalued assets, fraudulent transfers to family members or third parties, and phantom arrangements within business structures. If a court finds that assets have been hidden, there can be significant financial penalties and even criminal charges.
Courts will also scrutinise the administration of family trusts to determine whether trust assets form part of the matrimonial asset pool.
Forensic Accountants and Expert Valuers in High Net Worth Cases
High net worth divorces involve complex asset valuation, including privately held businesses, trusts and international holdings. Identifying and valuing the asset pool can be complicated due to the nature of these assets, which may include minority interests, share options and assets with conditions attached.
Specialist forensic accountants and professional valuers are often needed to resolve valuation disputes over privately held businesses and intellectual property. The Family Court may require forensic accountants to trace asset ownership and movements where one party is not forthcoming with financial information. Their expert findings can be presented as evidence in court proceedings.
Prenuptial and Postnuptial Agreements for High Net Worth Couples
High net worth couples often opt for prenuptial or postnuptial agreements, known in Australia as Binding Financial Agreements (BFAs), to clarify the division of assets in the event of separation or divorce. It may be beneficial for individuals with a high net worth to obtain a binding financial agreement at the commencement of the relationship in order to minimise the risk of lengthy disputes.
A BFA can provide significant protection by setting out in advance how the asset pool will be divided. Both parties must have received independent legal advice before signing such an agreement for it to be valid. It is important to be aware, however, that prenuptial or postnuptial agreements can be set aside by courts if found to be fraudulent, signed under duress or deemed unfair. Obtaining a well-drafted BFA with the benefit of experienced legal advice is therefore essential.
Tax Implications in High Net Worth Separations
Tax implications are crucial to consider in high net worth divorces due to the complexity of asset division. Selling or transferring assets as part of a financial settlement can trigger significant tax consequences. High net worth divorces often involve significant capital gains tax (CGT) liabilities associated with the sale or transfer of properties or businesses. Division 7A tax may also arise where business profits have been applied for personal expenses.
Understanding tax consequences is critical in structuring a high net worth property settlement. Some asset transfers may qualify for CGT rollover relief, but others may trigger a taxable event that must be factored into the overall settlement. Expert financial and tax advice is essential to ensure all liabilities are properly accounted for. The experienced NSW separation lawyers at JB Solicitors work closely with financial advisors and tax specialists to structure settlements in the most effective way.
Privacy, Confidentiality and Mediation in High Net Worth Australian Cases
High net worth divorce cases can attract unwanted media and public attention. Section 121 of the Family Law Act prohibits the publication of divorce proceedings where the parties are identifiable, covering journalistic writings, broadcasts and social media posts alike. It is important to sign a confidentiality agreement to ensure that any information gained through the separation process remains protected. High-profile individuals often use private arbitration or mediation to avoid public scrutiny.
Mediation and arbitration are frequently used in high net worth divorces to control outcomes and maintain privacy. Mediation allows for more flexible and cost-effective solutions than contested court proceedings, and can open up settlement options that would not otherwise be available. Where parties cannot reach agreement through mediation, the matter will proceed to the Federal Circuit and Family Court of Australia for determination.

The Legal Solution: Why You Need Experienced NSW Separation Lawyers
Reaching a settlement in a high net worth divorce case will take significantly longer than a typical divorce case. High net worth divorce cases have the potential to become long drawn-out court battles. This happens because it often becomes difficult to identify assets, especially when a high net worth individual owned property prior to the marriage. The assets involved are less straightforward, including large estates, foreign investments and assets that require specialist evaluations.
It is imperative that parties with a high net worth seek advice from a reputable family lawyer early. High net worth divorces often require a team of experts, including family lawyers, forensic accountants, financial advisors and professional valuers, to navigate the complexities involved. Engaging a family lawyer who has experience with high net worth divorces is essential to ensure that your rights and interests are protected.
The experienced separation lawyers at JB Solicitors can help draw up a confidentiality agreement between parties and can provide expert legal advice on property settlement matters and all issues that arise in high net worth cases.

Frequently Asked Questions
What is considered a high net worth divorce in Australia?
A high net worth divorce is generally considered to involve a combined asset pool of $5 million or more. The Australian Taxation Office categorises “wealthy individuals” as those with a net worth exceeding $5 million. Cases involving asset pools above $1 million also carry additional legal and financial complexity compared to standard separations.
Does the Family Court always split assets 50/50 in a high net worth divorce?
No. The Family Court of Australia aims to ensure a fair and equitable division of assets, which does not necessarily mean an equal split. The court weighs both financial and non-financial contributions alongside the future needs of each party before determining what is just and equitable in the specific circumstances.
Can my spouse hide assets during a separation?
Both parties have a legal duty to fully disclose all assets and liabilities. If a party conceals assets, the Family Court has the power to investigate, order full financial disclosure and set aside any property settlement reached without complete disclosure. The court can also reverse asset transfers made to defeat a claim. Forensic accountants can be engaged to trace hidden assets.
What is a Binding Financial Agreement and do I need one?
A Binding Financial Agreement (BFA), sometimes called a prenuptial or postnuptial agreement, sets out how assets will be divided in the event of separation. For high net worth individuals, a BFA at the start of a relationship can significantly reduce the risk of lengthy disputes. However, courts can set aside a BFA if it is found to be fraudulent, signed under duress or deemed unfair. Both parties must have received independent legal advice for it to be valid.
What role do forensic accountants play in high net worth divorces?
Forensic accountants are engaged to investigate complex financial structures, trace hidden or undisclosed assets, value privately held businesses and intellectual property, and ensure the full asset pool is properly identified for division. They work alongside your separation lawyer and can provide expert evidence to the court if required.
What tax issues should I be aware of in a high net worth property settlement?
Selling or transferring assets as part of a divorce settlement can trigger capital gains tax (CGT) and, in some cases, Division 7A tax on business profits that have been used for personal expenses. Expert financial and tax advice is essential to ensure the settlement is structured in the most tax-effective way and that all liabilities are properly accounted for before any agreement is finalised.
Can a prenuptial agreement be challenged in an Australian court?
Yes. A court can set aside a prenuptial or postnuptial agreement if it is found to be fraudulent, made under duress or deemed unfair to one party. The agreement must also comply with the formal requirements of the Family Law Act, including that both parties received independent legal advice before signing. An experienced separation lawyer can advise on the validity and enforceability of any existing agreement.
How long does a high net worth divorce typically take to resolve?
High net worth divorces often take much longer to resolve than standard separations, sometimes stretching over years. This is largely due to the complexity of identifying and valuing assets, obtaining expert reports from forensic accountants and valuers, and the potential for contested court proceedings. Seeking expert legal advice early is the most effective way to streamline the process and reduce overall costs.
