The Updated Family Law Rules About Financial Disclosure After Separation

Separating from a partner is hard enough. It becomes far more stressful when the other party refuses to be open about their financial circumstances.

Some people drag their feet on bank statements. Others downplay what their business earns, or keep accounts hidden altogether. Whatever the tactic, withholding financial information creates real friction and can seriously delay a property settlement. For anyone dealing with financial disclosure after separation, having a complete picture of the asset pool is an important part of reaching a fair outcome.

Following major reforms under the Family Law Amendment Act 2024 (which took effect on 10 June 2025), the rules around financial transparency in Australia are firmer and clearer than ever.

The Statutory Duty of Disclosure

The requirement to share financial information used to sit mainly in court rules and procedural guidelines. That is no longer the case. The duty of disclosure is now written directly into the Family Law Act.

This shift matters because financial transparency is no longer just a procedural expectation. It is a strict, legal obligation.

Both parties must give each other, and the court, a full, frank and complete account of their entire financial position. This requirement for full and frank disclosure in family law applies throughout the financial disclosure and property settlement process. The duty is not a one-off task. It begins as soon as negotiations or property proceedings start and continues until final orders are made or a Binding Financial Agreement is signed.

If your financial circumstances materially change during negotiations, there is a positive obligation to disclose those changes and provide any relevant documents. That could be a work bonus, an inheritance or a new liability. Legal practitioners and family dispute resolution practitioners are also required by law to tell clients about this duty and actively encourage them to comply.

For clients working with property settlement lawyers in Melbourne, this means financial disclosure should be treated as a core part of the settlement process rather than something dealt with only if the matter reaches court.

Categories of Required Financial Records

For a property settlement to be just and equitable, both parties must exchange documents relevant to their financial circumstances.

This includes all sources of income and earnings, including recent tax returns, notices of assessment, payslips and any government benefit statements. Parties must also provide bank and debt statements for every personal, joint, savings, offset and credit account, even if the account is no longer active or has a zero balance.

Disclosure goes well beyond income and banking. It also covers real estate titles, professional property valuations, motor vehicle registrations and detailed superannuation statements. Investments such as share portfolios, managed funds and cryptocurrency must be fully disclosed as well.

Where a business or trust is involved, the law requires company financial statements, tax returns and trust deeds to be produced. Any significant asset sales, transfers, gifts or disposals made since separation must also be documented, so the court can accurately assess the true value of the asset pool.

This becomes particularly important in a complex property settlement or larger asset pool, where companies, trusts, investments and other structures may make the true financial position less obvious. Sage Family Lawyers assists with property settlement matters involving these more complex financial arrangements, where establishing the full asset pool can be a critical first step.

What Counts as Withholding Financial Information

Withholding financial details isn’t limited to an outright refusal to hand over paperwork. Under Australian family law, non-disclosure takes several forms, from subtle delays to deliberate concealment.

Stalling, ignoring formal requests, or taking an unreasonable amount of time to complete disclosure all amount to non-compliance.

Partial or selective disclosure is another common tactic. A party might provide records for their everyday bank account while deliberately leaving out secondary savings accounts, line-of-credit facilities or overseas holdings.

More serious forms include moving cash into third-party accounts, underreporting business revenue, or deliberately deferring bonuses or commissions until after the settlement is signed. These issues can become particularly significant where there are concerns about hidden assets during a property settlement.

The law also explicitly recognises economic abuse as a form of family violence. This includes suppressing financial information to maintain power or control over a former partner, and courts can factor the impact of that behaviour into how property is divided.

Legal Consequences for Hiding or Withholding Assets

When a former partner fails or refuses to meet their duty of disclosure, the Family Law Courts have broad statutory powers to address the misconduct and make sure the compliant party is not disadvantaged.

One of the most powerful tools is the ability to draw adverse inferences. If an ex-partner refuses to provide financial documents, the judge can infer that the hidden assets are substantial and adjust the property split in favour of the compliant party based on the available evidence.

The court can also make costs orders. The party who withheld information may have to pay some or all of the other side’s legal fees caused by delays or formal enforcement applications.

If a property settlement has already been finalised and it later emerges that assets were hidden, the court can set aside the original agreement or consent orders and re-evaluate the asset pool entirely.

For serious or persistent refusal to disclose, courts can strike out the non-compliant party’s claims altogether or begin contempt of court proceedings, which carry significant penalties.

For someone concerned about undisclosed assets in a property settlement, speaking with a property settlement lawyer early can help establish what information is missing and what options are available before the issue causes further delay.

Practical Legal Steps When Facing Non-Disclosure

If you suspect your former partner is concealing assets or failing to provide full disclosure, there are clear procedural steps you can take. The process usually begins with a formal written request that sets out exactly what documentation is missing and gives a strict but reasonable deadline for compliance.

Sage Family Lawyers’ property settlement lawyers in Melbourne can assist with reviewing the financial information already provided, identifying gaps in disclosure and determining whether further documents or action may be required. This can be particularly important in high-value or complex property settlements where businesses, trusts, investments or multiple asset structures are involved.
