Setting Aside Family Law Property Orders in Victoria: Section 79A and Non-Disclosure of Assets 

A high-net-worth individual in Victoria who discovers that a former spouse concealed assets during a property settlement may be able to apply for setting aside property orders under section 79A of the Family Law Act 1975 (Cth). The Court will not reopen final orders merely because the result later appears unfavourable. The applicant must establish one of the statutory section 79A grounds, including that fraud, non-disclosure or another circumstance caused a miscarriage of justice. 

This issue commonly arises where company interests, trust assets, offshore holdings, cryptocurrency, related-party transactions, or substantial income were omitted or materially understated. Depending on the evidence, deliberate suppression of assets may amount to non-disclosure and fraud, particularly where the missing information affected the identification, valuation, or division of the asset pool. 

For former de facto partners, the corresponding power to set aside property orders appears under section 90SN. A successful application requires credible fresh evidence, a clear account of how the information was discovered, and proof that the non-disclosure was material enough to justify disturbing otherwise final property orders. 

What Does Section 79A Require Before Final Property Orders Can Be Set Aside? 

The principal provision is section 79A of the Family Law Act 1975 (Cth), which permits a court to vary or set aside final property orders made under section 79 in defined circumstances. For former de facto partners, the corresponding power is found in section 90SN. These provisions recognise that finality is important, but not where the process leading to the orders produced a legally significant injustice. 

The most relevant of the section 79A grounds for concealed assets is section 79A(1)(a). It applies where there has been a miscarriage of justice because of fraud, duress, suppression of evidence, failure to disclose relevant information, false evidence, or another circumstance. The Court must first determine whether the alleged conduct occurred and then whether it affected the integrity or fairness of the process. Establishing non-disclosure and fraud does not automatically require the original orders to be set aside. The Court retains a discretion after the statutory ground is established. 

In Barker v Barker [2007] FamCA 13, the Full Court explained that a miscarriage of justice arises where circumstances make the order contrary to law and justice in a way that concerns the integrity of the judicial process. Section 79A is therefore not a general right to renegotiate an unfavourable settlement or revisit an alleged error that should have been addressed by appeal. The applicant must connect the concealed information or other wrongdoing to the process by which the orders were made. 

Suiker & Suiker (1993) FLC 92-436 further illustrates the staged inquiry. The Court considers whether the alleged fraud, non-disclosure or other circumstance is proven, whether it produced a miscarriage of justice and, if so, whether the orders should be varied or set aside. 

This analysis operates alongside the parties’ continuing duty of full and frank disclosure. In financial proceedings, each party must provide timely disclosure of information relevant to their financial position. For high-value asset structures, that obligation may extend to companies, trusts, loans, indirect interests, overseas holdings, and transactions involving related parties. 

How Does the Court Decide Whether to Set Aside Property Orders for Non-Disclosure? 

What evidence is needed to prove that assets were concealed? 

An applicant needs more than suspicion or a later disagreement about value. The Court will require credible fresh evidence identifying the asset, interest, transaction, or income stream that was not disclosed. Relevant material may include company and trust records, bank statements, tax returns, title searches, cryptocurrency records, loan documents, or communications with financial advisers. 

The evidence should explain when and how the information was discovered, why it was unavailable when the original orders were made, and how it conflicts with the former spouse’s earlier disclosure. 

Must the non-disclosure have affected the original outcome? 

Yes. Establishing that information was omitted does not, by itself, prove a miscarriage of justice. The applicant must show that the non-disclosure affected the fairness of the process or could realistically have influenced the orders made. 

The Court considers the value and nature of the undisclosed asset, its proportion within the overall property pool and its relevance to the parties’ financial positions. A minor omission may not justify reopening a substantial settlement. Concealed company equity, trust interests, offshore holdings, or significant related-party loans may be different. 

Does the applicant have to prove deliberate fraud? 

Not necessarily. Non-disclosure and fraud may overlap, but section 79A separately refers to fraud, suppression of evidence, failure to disclose relevant information and false evidence. Relief may therefore be available even where deliberate dishonesty cannot be established. 

Evidence of intentional suppression of assets, however, may strengthen the application. It can also influence the Court’s assessment of credibility and whether discretionary relief should be granted. 

Will the Court automatically reopen the entire settlement? 

No. Proving one of the section 79A grounds gives the Court power to intervene, but it does not dictate the remedy. The Court may set aside the original orders, vary in provisions, or decline relief where reopening the settlement would not produce a just result. 

The Court may consider whether assets have been sold, third parties have acquired interests, funds remain traceable, and the parties have reorganised their affairs in reliance on the orders. Finality remains an important consideration. 

How quickly should an applicant act after discovering hidden assets? 

An applicant should act promptly. Delay may make documents harder to obtain, assets more difficult to trace, and the circumstances of discovery less persuasive. It may also affect the Court’s exercise of discretion. 

The applicant should preserve the original disclosure, document how the new evidence emerged, and obtain targeted financial records before commencing proceedings. The same evidentiary discipline applies to former de facto partners seeking relief under section 90SN. 

What Practical Disputes Arise When Hidden Assets Are Discovered After Final Orders? 

Disputes commonly arise where one party controlled a company or family trust and disclosed the formal ownership structure without revealing the practical value of their control or financial benefit. Later-produced financial statements, trustee resolutions, loan accounts, or tax records may expose retained earnings, unpaid entitlements, related-party receivables, or distributions that were not identified during the original proceedings. In these matters, understanding how the Court assesses trust control can help distinguish formal ownership from effective financial control. The issue is whether the earlier disclosure gave an incomplete or misleading account of the party’s true financial position and whether that affected the orders. 

Another recurring dispute concerns liabilities that reduced the apparent value of the property pool. A former spouse may later discover that a substantial loan from a parent, associated company or trust was never enforced, lacked proper documentation, or was subsequently waived. Bank records, loan agreements, repayment histories, and accounting treatment are often decisive in determining whether the liability was genuine. 

Applications also arise after assets are traced to relatives, business associates, or controlled entities. Company searches, land records, taxation documents, and insolvency investigations may reveal transfers made before or during the proceedings. The Court will examine the timing, consideration paid, commercial rationale and whether the former spouse retained effective control or benefit. Those facts may support allegations of suppression of assets or incomplete disclosure. 

Offshore accounts, foreign companies, cryptocurrency, and income received through private structures create additional evidentiary difficulties. The practical task is to convert partial records into admissible fresh evidence linking the asset or income stream to the former spouse. Unsupported allegations can weaken an otherwise credible application and increase costs. 

Even where non-disclosure is established, the parties often dispute whether it was material. Valuation evidence may be required to determine what the asset was worth when the orders were made and whether full disclosure could realistically have changed the result. In high-value property matters, the strength, chronology, and financial coherence of the evidence usually matter more than the number of allegations advanced. 

What Should Be Assessed Before Bringing or Defending a Section 79A Application? 

Before commencing an application for setting aside property orders under section 79A, the first task is to test the evidence, not the allegation. A client should identify the asset or transaction said to have been concealed, explain how it was discovered, and show why it could have affected the original property outcome. Suspicion alone is not enough, and premature accusations of fraud can increase costs and complicate settlement discussions. 

The evidentiary strategy should focus on chronology, source documents, and materiality. Original disclosure should be compared against later bank records, tax returns, company accounts, trust documents, title searches, and communications with advisers. Where valuation is contested, expert evidence may be needed to establish the asset’s value when the orders were made, rather than its current value. 

Timing also matters. Delay can make tracing more difficult and may affect the Court’s exercise of discretion, even where the alleged non-disclosure is serious. Early preservation of records, targeted subpoenas, and a disciplined forensic accounting brief can be critical. Where there is an ongoing risk that property may be moved or dealt with, advice on preserving the asset pool before settlement may also be relevant. 

For a respondent, the strategy is not limited to denying concealment. It may involve showing that the information was disclosed, immaterial, already known, incapable of changing the outcome or unrelated to any miscarriage of justice. The likely practical result should also be assessed. Even if a statutory ground is established, the Court may refuse to reopen the settlement where doing so would create further injustice or disturb third-party interests. 

Frequently Asked Questions 

What Should You Do After Discovering Undisclosed Assets Following Final Property Orders? 

Discovering that a former spouse may have concealed assets does not automatically reopen a completed property settlement. An application for setting aside property orders under section 79A requires reliable evidence, proof of material non-disclosure and a clear connection between that conduct and a miscarriage of justice. Prompt investigation is important, particularly where companies, trusts, offshore interests, or related-party transactions are involved.
