1. Why Final Property Orders Are Intended to Be Final

Property orders under sections 79 and 90SM of the Family Law Act 1975 (Cth) are designed to resolve the financial dispute between separating parties on a once-and-for-all basis. Finality serves several important purposes: it allows the parties to refinance and transfer property; it protects third parties such as lenders, purchasers and trustees who rely on the orders being implemented; it allows tax, duty and superannuation outcomes to be implemented with certainty; and it permits the parties to rearrange their financial lives without the constant threat of further litigation.

Both judicially determined orders and Consent Orders are final orders for these purposes. The fact that an order was made by consent does not weaken its finality. If anything, the policy reasons supporting finality of orders made by agreement are particularly strong: the parties have, with the benefit of advice, negotiated and agreed the outcome, and third parties and the Court are entitled to assume that the agreed outcome will hold.

The starting position is therefore that final property orders cannot be reopened. The grounds for reopening them are exceptions to this starting position, not the rule.

2. The Correct Remedy Must Be Identified First

Many problems with orders look superficially like grounds to reopen the settlement but are properly dealt with by a different remedy. The first step in any review of final orders is to identify the right pathway. Choosing the wrong process can result in missed deadlines, wasted costs, prejudice to the applicant's case and difficulty later in convincing the Court to allow the right application to be made out of time or in a different form.

The principal pathways are: appeal; an application to vary or set aside property orders under section 79A or section 90SN; enforcement; correction of an accidental slip or drafting error; clarification or consequential orders; variation by consent of all parties; setting aside a BFA under the separate Part VIIIA or Part VIIIAB framework; and review or setting aside of an arbitral award. Each has its own substantive criteria and procedural rules. The relationship between them should be analysed before any step is taken.

3. Appeal versus Reopening

An appeal is generally directed at alleged error in the original decision: an error of law, an error of fact, a discretionary error such as taking into account an irrelevant consideration or failing to take into account a relevant consideration, or procedural unfairness in the conduct of the proceedings. An appeal proceeds on the record of the original case, sometimes supplemented by fresh evidence in limited circumstances.

Appeal rights are subject to tight time periods set out in the current appeal rules of the Federal Circuit and Family Court of Australia and, where relevant, the higher appellate jurisdictions. The current periods and any extension provisions should be verified against the live rules before any decision to appeal is made; this article deliberately does not state a fixed appeal period. Where the appeal period has passed, the right to appeal does not simply revive because new information emerges; later misconduct or later impracticability is generally addressed under section 79A or section 90SN, not by appeal.

A stay of the original orders pending appeal is sometimes appropriate where there is a risk that implementation will cause irreversible harm. A stay does not follow automatically from filing an appeal — a separate application is usually required.

4. Enforcement versus Setting Aside

Many disputes after final orders are not really disputes about whether the orders should remain in force — they are disputes about whether the other party is complying with them. Failure to pay an agreed amount, sign a transfer, refinance the family home, sell a property, vacate premises, close a joint account, discharge a liability, transfer company shares or provide documents are all matters that generally call for enforcement, not reopening.

Enforcement tools available under the current Court framework may include orders compelling compliance, the appointment of a person to sign on behalf of a defaulting party, enforcement warrants, sale orders, interest on unpaid amounts, costs orders and, where legally available, contempt or contravention consequences. The precise procedural mechanism should be confirmed against the current Federal Circuit and Family Court of Australia (Family Law) Rules.

Choosing enforcement does not preclude considering whether default also engages the default-based setting-aside ground in section 79A(1)(c) or section 90SN(1)(c), but these remedies are not the same. Enforcement seeks to compel performance of the existing orders; default-based reopening seeks to change them.

5. Correction of an Accidental Slip or Omission

The Court has procedural powers to correct an accidental slip or omission in an order, and to make consequential orders to give effect to the substantive decision, without reopening the underlying bargain. Typical examples include an incorrect lot or title number, an obvious misspelling of a party's name, a mathematical transcription error in a payment calculation, omitted machinery wording required to give effect to an asset transfer, or ambiguity about which document a party must sign.

Correction is not a vehicle for renegotiating the settlement. The line between fixing an obvious slip and changing the substantive bargain is sometimes sensitive — for example, where there is ambiguity in how a property is to be valued or how a sale is to be conducted. Where there is genuine dispute about what the orders mean, the appropriate course is often a clarification application rather than a unilateral attempt to read the orders in a particular way.

6. Section 79A and Section 90SN Grounds Overview

Section 79A applies to property orders made under section 79 in relation to a marriage. Section 90SN applies to property orders made under section 90SM in relation to an eligible de facto relationship. The grounds in each provision broadly correspond, but the precise wording, including any later amendment, should always be checked on the Federal Register of Legislation before any application is made.

The grounds, in general terms, cover: miscarriage of justice (caused by fraud, duress, suppression of evidence, the giving of false evidence or some other qualifying circumstance); impracticability of carrying out the orders because of circumstances arising after they were made; default by a party where, because of the default, it is just and equitable to vary or set aside the order and make another order; exceptional circumstances relating to the care, welfare and development of a child causing hardship; certain proceeds-of-crime circumstances; and variation or setting aside by consent of all parties to the original proceeding. Establishing a ground is necessary but not sufficient — the Court still has to decide what to do in the exercise of its discretion.

7. Miscarriage of Justice

Miscarriage of justice is the most frequently invoked ground and the most frequently misunderstood. It is not a roving fairness inquiry. The Court must identify what occurred, whether it was material to the making of the order, whether it affected the terms of the order in a real sense and whether justice has therefore miscarried. The applicant bears the persuasive burden.

The provision identifies particular kinds of circumstances that can give rise to a miscarriage of justice: fraud, duress, suppression of evidence, failure to disclose relevant information, the giving of false evidence and another qualifying circumstance. Each is addressed below. The unifying theme is that the integrity of the process leading to the order has been undermined in a way that the law does not require the other party to bear.

8. Fraud

Fraud, in this context, generally requires deliberate dishonesty by a party (or someone for whom that party is responsible) that affected the orders made. Possible examples include concealed bank accounts, hidden company interests, false liabilities, sham loans, deliberate undervaluation, secret property transfers, forged records, false statements about ownership, undisclosed cryptocurrency or overseas assets, fabricated debts and collusive transactions with relatives.

Allegations of fraud carry significant consequences for the alleged perpetrator and, often, for the broader matter. They should not be made lightly. Mere assertion is insufficient; the Court generally requires clear evidence. Disputes about valuation, differences of opinion between experts, aggressive but lawful settlement conduct and even poor record keeping are not, by themselves, fraud.

9. Suppression of Evidence and Non-Disclosure

The disclosure obligation in Australian family-law property proceedings is wide and continuing. Suppression of evidence and failure to disclose relevant information can amount to a miscarriage of justice where the omission was material to the order. Suspect categories include concealed assets, omitted income, related-party dealings, overseas holdings, tax liabilities, guarantees, superannuation and post-separation transactions. The Parke Lawyers financial disclosure and hidden assets article covers the disclosure framework in detail.

The Court's focus on a setting-aside application is generally on materiality, knowledge, timing, causation and effect: what was undisclosed, when the disclosing party knew about it, whether the applicant could reasonably have obtained it independently, when the applicant discovered the omission, whether it would realistically have changed the orders, and what should now be done. Trivial or immaterial non-disclosure does not justify reopening a settlement.

10. False Evidence

False evidence can support a miscarriage-of-justice ground where the evidence in question was material to the order. Possible categories include false evidence about asset ownership, value, income, liabilities, trust control, company accounts, family loans, health, employment, sale proceeds, tax and financial resources. The Court distinguishes between deliberate falsehood, honest but inaccurate recollection, opinion later shown to be wrong, expert disagreement and changed circumstances after the orders.

11. Duress

Duress in the section 79A and section 90SN context generally requires illegitimate pressure that overbore the will of a party and was material to the making of the order. It is distinct from ordinary commercial pressure to settle, emotional difficulty, disappointment, advice a party later regrets and the lawful insistence on legal rights. Possible evidence includes threats, coercion, control of money, isolation, urgency manufactured by one party, threats concerning children, housing or immigration, the inability to obtain advice and contemporaneous communications. Duress is fact-sensitive; the Court will examine the totality of circumstances and any corroborating evidence.

12. Family Violence and Financial Abuse

Coercive control, prevention of independent advice, withholding of financial information, threats, forced borrowing, misuse of identity, control of communication, pressure to sign, isolation and interference with legal representation may all be relevant context to an application alleging duress or another miscarriage of justice. The post-10 June 2025 amendments to the Family Law Act 1975 (Cth) expressly recognise the economic effect of family violence in the property-settlement framework, which may influence both the underlying fact analysis and the Court's discretion.

Family-violence allegations do not automatically establish duress or miscarriage of justice. The statutory ground still requires proper legal analysis, the respondent retains procedural fairness and the Court will assess the evidence with care. Where family violence is in issue, trauma-informed preparation, support services and appropriate safety measures should be considered alongside the legal analysis.

13. “Any Other Circumstance”

Section 79A also contemplates miscarriage of justice for other qualifying reasons. This is not an unrestricted general fairness discretion. The current appellate authority on the scope of the residual category — including the relationship between the circumstance relied on and the miscarriage of justice, mistake, lack of capacity, procedural unfairness and circumstances undermining genuine consent — should be checked before relying on it. Finality continues to influence how readily this category is engaged.

14. Impracticability

Section 79A(1)(b) and section 90SN(1)(b) recognise circumstances arising after the orders were made that make it impracticable to carry them out, or impracticable to carry out a part of them. Impracticability is more than inconvenience, an increase in cost, an unfavourable financing offer, delay, changed market conditions or a transaction becoming less attractive.

Possible scenarios may include an asset no longer existing (for example, destruction by fire or confiscation), a legal prohibition arising after the orders, the failure of a corporate or trust mechanism on which the orders depended, an unavailable third-party approval, or a foreign-law obstacle that prevents implementation. The impracticability must arise from circumstances after the orders, not be inherent in the bargain itself.

15. Failed Refinance

Refinance difficulty is among the most common scenarios advanced as impracticability, and among the most commonly rejected. The Court will look at what the orders actually provided. Did the orders contain a sale fallback if refinance proved impossible? Was finance assumed or guaranteed by the orders? Has the applicant's financial position deteriorated since the orders were made? Is the issue lender refusal of a particular product or absence of any available finance? Has the applicant defaulted on interim payments in a way that has affected their credit? Is sale or other enforcement available? See the Parke Lawyers mortgage and household expenses article for the broader context.

16. Default

Section 79A(1)(c) and section 90SN(1)(c) provide a distinct ground where a party has defaulted in carrying out an obligation under the order and, in the circumstances that have arisen because of the default, it is just and equitable to vary the order or set it aside and make a different order. Examples include failure to pay an equalisation amount, failure to refinance within the prescribed time, failure to transfer property, failure to sell, the dissipation of property, the encumbering of an asset and allowing a business or property to deteriorate.

Default-based reopening is distinct from ordinary enforcement. The question is whether the consequences of the default are such that the original orders should be modified to do justice between the parties, not merely whether the defaulting party should be compelled to perform. In many cases, enforcement is the appropriate remedy and the default ground does not need to be engaged.

17. Exceptional Child-Related Circumstances and Hardship

Section 79A(1)(d) and section 90SN(1)(d) recognise a narrow ground where exceptional circumstances relating to the care, welfare and development of a child of the marriage or relationship have arisen since the orders were made, and either the child or the applicant (where the applicant has caring responsibility for the child) will suffer hardship if the order is not varied or set aside.

The exceptional-circumstances test is demanding. Ordinary changes in parenting arrangements, schooling, expenses or income are not enough. The ground typically contemplates events such as the onset of serious disability, unexpected major medical or care needs, a radical change in living arrangements, or the collapse of a care plan that underpinned the orders. The precise statutory language should be checked for both marriages and eligible de facto relationships.

18. Proceeds-of-Crime Circumstances

The Act recognises specific situations in which a proceeds-of-crime order may affect the property covered by a family-law order. At a high level, the Court may vary or set aside the family-law order where particular kinds of proceeds-of-crime orders apply to the property, and government authorities may be involved. Where this ground is engaged specialist criminal and proceeds-of-crime advice is generally required; this article does not provide criminal-asset-avoidance strategies.

19. Variation or Setting Aside by Consent

Where all parties to the original proceeding consent, the Court may have power on the application of an affected person to vary or set aside the original order and to substitute new orders. Agreement alone does not rewrite existing orders. A further Court application is generally required, the substituted orders must be properly drafted, tax, duty, superannuation and creditor consequences require review, and third-party and trustee procedural fairness may be needed before any substituted order is made. Privately ignoring or replacing final orders is not a substitute for going through the correct procedural mechanism.

20. Consent Orders

Consent Orders are Court orders. They are not merely a private contract. They are intended to be final, they require full disclosure before they are made, and they may be challenged only through recognised legal pathways — principally appeal (in limited circumstances), section 79A or section 90SN, enforcement, correction of an accidental slip, and variation by consent. The Parke Lawyers Consent Orders article explains how Consent Orders are obtained and the disclosure framework that supports them.

The fact that an order was made by consent does not give a party an unrestricted right to withdraw consent later. The Court will not set aside Consent Orders simply because one party now regards the agreed division as ungenerous, has received later advice from a different lawyer or is unhappy with how implementation has worked out.

21. Orders Made After a Contested Hearing

Orders made after a contested hearing are subject to the same statutory grounds for variation or setting aside, but the available remedies are slightly different in practice. An appeal addresses alleged error in the original decision and is bound by the record (subject to limited fresh-evidence rules). Section 79A or section 90SN may be engaged where evidence was unavailable at trial, where fraud is later discovered, where impracticability has emerged after the orders or where default-based reopening is apt. A setting-aside application is not a second appeal and should not be drafted as one.

22. Binding Financial Agreements Are Different

A Binding Financial Agreement under Part VIIIA (married couples) or Part VIIIAB (de facto) of the Family Law Act 1975 (Cth) is a statutory agreement, not a Court order. The setting-aside provisions are different from section 79A and section 90SN. Potential grounds may include fraud, non-disclosure entered into to defeat creditors, void, voidable or unenforceable agreements, impracticability, unconscionable conduct, certain forms of hardship involving a child, issues affecting superannuation interests and failure to comply with the statutory independent-advice requirements. The exact grounds should be verified on the Federal Register of Legislation before any application is made. The Parke Lawyers BFA article covers the BFA framework.

A BFA cannot be rewritten under the property-order provisions, and applying the wrong framework generally results in dismissal of the application.

23. Informal Property Arrangements

Where parties relied on verbal arrangements, unsigned drafts, emails, private division of assets, an unapproved deed or transfers made without Consent Orders or a valid BFA, the question is generally not whether to set aside Court orders but whether the informal arrangement is enforceable at all, and within what time limit. These cases sit at the intersection of family law, contract and property law and require careful procedural analysis. Time limits under section 44 of the Family Law Act 1975 (Cth) continue to apply.

24. Fresh Evidence

Fresh evidence in this context may include newly discovered bank accounts, company records, trust documents, cryptocurrency records, foreign-title searches, tax returns, communications revealing concealment and forged loan records. The Court distinguishes between evidence that existed but was hidden, evidence that could reasonably have been obtained with due diligence at the original time, events arising after the order, a new expert opinion on the same underlying material and ordinary later changes in value. The pathway depends on the characterisation of the new material and the orders in question.

25. Hidden Companies and Trusts

Concealed shareholdings, undisclosed corporate trustees, appointor powers, beneficiary loans, unpaid present entitlements, related-party transfers, false liabilities, altered ledgers and hidden distributions are common subjects of setting-aside applications. Company assets are not automatically personal property of the shareholder; trust property is held for the beneficiaries on the terms of the deed. Careful expert analysis is generally required. The Parke Lawyers family trusts article covers the broader treatment of trusts.

26. Undisclosed Overseas Assets and Cryptocurrency

Overseas land, foreign companies, foreign bank accounts, digital wallets, exchange records, beneficial-ownership chains, translated documents, foreign legal evidence, tracing and tax all raise evidentiary issues that frequently arise in setting-aside applications based on non-disclosure. This article does not provide concealment or evasion instructions. Specialist forensic, foreign-law and tax advice is generally required.

27. Incorrect Valuations

A later disagreement with the valuation that underpinned the original orders is not, by itself, a ground to reopen them. The Court distinguishes between honest expert disagreement, negligent valuation, valuations procured on deliberately false instructions, valuations based on concealed information, material mistake, later market changes and a new expert opinion obtained after the settlement. The Parke Lawyers asset valuations article covers the valuation framework.

28. Later Changes in Property Value

Ordinary later property growth, market decline, business success, investment loss, interest-rate changes, exchange-rate movements and cryptocurrency volatility do not, by themselves, reopen final orders. The fact that one party received an asset that has since appreciated significantly, or that another party received cash that has since depreciated in real terms, is not a basis for challenging the settlement. Value changes are different from impracticability and from fraud.

29. Later Bankruptcy or Insolvency

A trustee in bankruptcy, a personal-insolvency agreement trustee, creditors and the interaction between vested bankruptcy property and family-law orders all raise difficult questions. Bankruptcy does not automatically void or reopen family-law orders. In appropriate cases a trustee may be a person affected with standing to apply, and the Court may need to consider creditor interests against finality. See the Parke Lawyers article on a former spouse becoming bankrupt during property settlement.

30. Creditor Applications

A creditor whose ability to recover a debt is affected by a property order may, in some circumstances, be a person affected with standing to apply. Standing, evidence of the debt, the effect of the order, procedural fairness, secured and unsecured status, government creditors, related-party creditors and concerns about sham debts are all relevant. See the Parke Lawyers debts after separation article for the debt-allocation framework.

31. Bona Fide Purchasers and Third Parties

Purchasers, lenders, trustees, companies, beneficiaries, creditors, superannuation trustees and other persons who relied on the orders being implemented are likely to be relevant to the Court's consideration of what remedy, if any, to grant. Completed third-party transactions may constrain the available relief and inform whether partial variation, substitution or compensatory orders are appropriate.

32. Death of a Party

Property proceedings already commenced may, in defined circumstances, be continued by or against the legal personal representative of a deceased party. Enforcement against an estate, whether substituted relief remains appropriate, the impact on estate administration and the position of third-party beneficiaries all require careful analysis. The precise statutory and procedural framework should be confirmed against the current Act and Rules. These proceedings should not be confused with commencing an original property case after death.

33. Delay and Time

Although section 79A and section 90SN do not contain a single fixed limitation period in the same way that section 44 governs the commencement of original property proceedings, time is critical. Evidence deteriorates. Witnesses become unavailable. Third parties acquire interests. Transactions are completed. Tax and duty positions are locked in. Prejudice to the respondent grows. The Court's discretion is informed by the applicant's promptness, and equitable considerations of laches and acquiescence may also be relevant.

The safest course is to obtain advice as soon as the issue is discovered, document the date and circumstances of discovery, preserve relevant evidence and act promptly rather than to assume the absence of a fixed numerical period means there is no time concern.

34. Court Discretion

Even where a statutory ground is established, the Court is not required to vary or set aside the orders. The Court considers the seriousness of the conduct or event, causation, materiality, the applicant's own conduct, delay, prejudice to the respondent and any third parties, whether variation of part of the orders is sufficient, whether setting the orders aside would achieve justice and whether substituted orders should be made. The threshold ground is necessary but not sufficient.

35. Possible Outcomes

Possible outcomes of a setting-aside application include dismissal, variation of part of the original orders, setting aside part or all of the orders, substitution of new property orders, preservation of completed transactions, protection of third parties, implementation orders, a stay of enforcement, additional disclosure orders and costs orders. The Court does not promise restoration to the parties' pre-orders positions.

36. What Happens to Property Already Transferred

Completed title transfers, sales to third parties, cash already spent, refinances, paid tax and duty, company-share transfers, superannuation splits and insolvency outcomes all raise tracing and recovery issues. The Court considers practical reversibility as a separate question from establishing a ground. Where reversal would prejudice innocent third parties, the Court may prefer compensatory or substitutional orders directed at the wrong-doer.

37. Tax and Duty Consequences

Reversing a transfer, substituting new orders, selling rather than transferring, the CGT roll-over assumptions baked into the original orders, Victorian transfer-duty relief, company or trust changes, debt forgiveness, indemnities and the need to amend earlier tax returns can all flow from setting-aside outcomes. A second transaction does not automatically receive the same concession as the original transaction. The Parke Lawyers tax and CGT article covers the underlying tax framework.

38. Superannuation Orders

Already-implemented payment splits, procedural fairness to the trustee, valuation methodology, implementation timing, fund changes between settlement and any substituted order, death or retirement and the underlying setting-aside or variation pathway must all be considered where superannuation is involved. Fund-specific implementation advice should be obtained.

39. Interim Protective Relief

Where there is a real risk that implementation of existing orders, dealings with property or the destruction of evidence will frustrate a genuine setting-aside application, urgent relief should be considered: a stay of the existing orders, an injunction, a preservation order, a freezing order, a prohibition on sale or transfer, account-restraint orders, document-preservation orders, an urgent disclosure order or a caveat where legally available. See the Parke Lawyers articles on urgent injunctions in Victoria and freezing orders in Victoria. Urgency does not, however, establish the underlying ground.

40. Forensic Accounting and Valuation Evidence

Forensic accountants may assist with tracing hidden assets, reconstructing accounts, identifying related-party dealings, business valuation, identifying false liabilities, trust and company analysis, tax analysis and quantifying materiality. Experts do not, however, decide whether the statutory ground is established — that is for the Court. Joint instruction, proportionate scope and properly framed assumptions tend to produce the most useful reports.

41. Disclosure After Final Orders

Once final orders have been made the formal disclosure regime continues to apply only in defined circumstances. In support of a setting-aside application, voluntary disclosure, subpoenas, notices to produce, third-party records, registry searches, affidavit evidence and expert review may all be available, subject to the current Rules. Surveillance and unlawful access are not appropriate methods and this article does not provide instructions on them.

42. Pre-Action Procedures and Dispute Resolution

Whether the current pre-action procedure requirements apply to an application to vary or set aside existing orders depends on the precise type of application, the available exemptions and the current practice directions of the Federal Circuit and Family Court of Australia. Genuine fraud allegations, urgency, real risk of asset dissipation and safety concerns may justify exemption. Negotiated variation by consent should be considered where it is realistically available.

43. Costs and Litigation Risk

Setting-aside applications can be expensive. Legal fees, forensic accounting, valuations, subpoenas, third-party participation, urgent applications and extended hearings all add to the cost. Costs may be ordered against unsuccessful applicants, particularly where unsupported allegations have been made, reasonable settlement offers have been refused or conduct has been unreasonable. Costs recovery is never guaranteed.

44. Settlement of a Setting-Aside Application

Many setting-aside applications resolve by agreement: variation by consent, substitution of orders, payment adjustment, sale, indemnity, release, additional disclosure, costs and implementation safeguards. Any agreement should be formalised through the correct legal mechanism — substituted Consent Orders or, in defined circumstances, a properly executed BFA — rather than relying on private documents that may have no family-law effect.

45. Action Plans

Action plan A — discovering a hidden asset. Obtain the sealed final orders and the disclosure material that supported them. Document the date and circumstances of discovery. Preserve all evidence, including electronic communications. Obtain independent legal advice before taking any further step. Consider whether to seek a stay of any outstanding implementation. Obtain forensic accounting or valuation evidence proportionate to the issue. Assess materiality. Identify affected third parties. Consider whether negotiated variation may resolve the matter. If not, prepare focused affidavit evidence directed at the specific statutory ground.

Action plan B — accused of fraud or non-disclosure. Do not destroy or alter records. Obtain independent legal advice immediately. Identify the specific allegations and the evidence relied on. Locate the relevant historical records. Consider whether the alleged omission was material. Avoid informal communications with the other party about the allegation. Engage a forensic expert where appropriate. Address procedural fairness in responding to any application.

Action plan C — creditor, trustee or affected third party. Identify the precise order alleged to affect recovery. Identify the basis for standing as a person affected. Obtain evidence of the debt or interest. Consider whether negotiated resolution with the parties is realistic. Assess the interaction with any insolvency framework. Address procedural fairness and the risk of an adverse costs order before filing.

46. Worked Examples

Example A — undisclosed bank account. Party A discovered after Consent Orders were made that Party B held an offshore account containing $480,000 that had not appeared in the disclosure or the balance sheet. The account had been operative during the relationship and was funded with money from a jointly operated business. The omission is potentially material and may support a miscarriage-of-justice ground. The likely focus is on what Party B knew, when, whether the account should have been disclosed and whether disclosure would realistically have changed the orders.

Example B — hidden cryptocurrency. Party A discovered that Party B held cryptocurrency in wallets that had not been disclosed and which had been transferred shortly before the orders. Tracing and forensic evidence are likely to be essential. The application requires careful attention to ownership, value at relevant dates and whether the omission was material to the orders.

Example C — omitted company interest. A shareholding in a private company was not disclosed in the application for Consent Orders. The company holds substantial assets and the shareholding has significant value. The omission is likely to be material. The shares are property; the underlying company assets generally are not personally divisible.

Example D — false family-loan liability. A purported family loan of $250,000 was included as a liability in the balance sheet. The loan was never genuinely owed. The inclusion materially understated the pool and may support a miscarriage-of-justice ground based on false evidence and suppression of the real position.

Example E — property transferred to a relative. Shortly before the orders Party B transferred a valuable property to a sibling for nominal consideration. The transaction may be relevant to both the existence of a ground and the appropriate remedy. Third-party joinder may be required.

Example F — signing after threats and financial control. Party A signed Consent Orders after a sustained period of coercive control, threats concerning the children, and being prevented from obtaining independent advice. The application engages duress and family violence and will require careful evidence, including contemporaneous communications, counselling records and corroborating evidence where available.

Example G — failed refinance. The orders required Party A to refinance the family home within six months and pay Party B $400,000. Multiple lenders have declined. The orders did not contain a sale fallback. Whether the situation amounts to impracticability or merely inconvenience, and whether enforcement (sale orders or appointment of a person to sign) is the appropriate remedy, will be central.

Example H — default on equalisation payment. Party B has failed to pay an equalisation amount. The first question is generally enforcement. The default ground may also be available where the consequences are such that variation of the orders is required to do justice — for example, where the asset retained by Party B has been dissipated.

Example I — asset sold before transfer. An investment property that Party A was to receive under the orders has been sold by Party B to a third party. Practical reversibility is constrained by the position of the bona fide purchaser. Compensatory or substitutional orders are likely to be more readily available than reversal of the sale.

Example J — exceptional new care needs of a child. After the orders, a child has been diagnosed with a serious medical condition requiring intensive, long-term care that materially changes the housing and financial requirements of the primary carer. Whether the exceptional-circumstances child-related ground is engaged depends on the precise statutory language and the facts; the threshold is demanding.

Example K — ordinary property growth. The family home retained by Party A has appreciated substantially since the orders. Party B regrets the agreed division. Ordinary later growth in value is not a ground.

Example L — later business downturn. A business retained by Party A has declined sharply. Party A seeks to reopen the settlement. Ordinary later decline in value is not a ground.

Example M — creditor unable to recover. A creditor has a substantial debt against Party B. The orders transferred Party B's main asset to Party A. The creditor may be a person affected for the purposes of an application; standing, evidence of the debt and the timing of the transactions will be central.

Example N — bankruptcy after orders. Party B has become bankrupt after orders were made. Bankruptcy does not automatically void the orders. The trustee may, depending on the circumstances, have standing and creditor interests may need to be considered.

Example O — bona fide purchaser. A third party has acquired property from Party B in good faith and for value. Even where a ground against Party B is established, the position of the bona fide purchaser will heavily influence the available remedy.

Example P — enforcement preferred. Party B has refused to sign a transfer required by the orders. The orders themselves remain workable. Enforcement (including appointment of a person to sign) is the appropriate remedy, not setting aside.

Example Q — appeal alleging legal error. Party A asserts that the trial judge misapplied the statutory framework. The appropriate pathway is an appeal within the appeal period, not a setting-aside application.

Example R — BFA challenged. The parties signed a BFA before separation. After separation Party A seeks to set it aside. The applicable framework is Part VIIIA, not section 79A or section 90SN.

Example S — consent variation. Both parties accept that the original orders are unworkable in the changed circumstances and have agreed substituted orders. A further Court application is generally required to give effect to the substitution; private documents alone do not replace the existing orders.

Example T — tax consequences of substituted orders. Substituted orders require a further transfer that would attract CGT and duty consequences distinct from those of the original orders. Specialist tax and duty advice is needed before the substituted orders are made.

None of these examples produces a guaranteed outcome and none is a Parke Lawyers matter; they illustrate principles only.

47. Common Mistakes

• Assuming that an unfavourable result is enough to reopen orders
• Confusing appeal with setting aside, or running both in the wrong order
• Waiting too long before seeking advice
• Alleging fraud without sufficient evidence
• Treating immaterial non-disclosure as decisive
• Filing a setting-aside application when enforcement is the appropriate remedy
• Privately changing or ignoring final orders
• Failing to consider third parties before commencing the application
• Disposing of property after discovering concealment
• Failing to seek a stay where implementation would cause irreversible harm
• Equating refinance difficulty with impracticability
• Relying only on a new valuation that disagrees with the original one
• Confusing a BFA with Consent Orders and applying the wrong framework
• Overlooking tax, duty and superannuation consequences
• Failing to preserve evidence
• Using obsolete forms or service routes
• Assuming that a successful threshold application guarantees a better substantive settlement

48. Practical Action Plan

1. Obtain the sealed final orders and any reasons for judgment.
2. Identify whether the instrument is a Court order, Consent Order, BFA or arbitral award.
3. Determine whether the real issue is appeal, enforcement, correction or setting aside.
4. Record when the issue was discovered and how.
5. Preserve documents and electronic records.
6. Identify the precise statutory ground relied on.
7. Assess materiality and causation.
8. Identify affected third parties.
9. Consider whether urgent protective orders are necessary.
10. Obtain disclosure, accounting, valuation or foreign-law evidence in proportion to the issue.
11. Assess delay, costs and practical reversibility.
12. Consider negotiated variation where legally available.
13. Prepare focused affidavit evidence.
14. Account for tax, duty, superannuation and creditor consequences.
15. Formalise any replacement outcome through valid Court orders.

49. Urgent-Advice Triggers

• You have just discovered an undisclosed asset and the implementation period is still running.
• You are within the appeal period for a recent judgment and need to decide whether to appeal.
• The other party is about to deal with property in a way that may frustrate a setting-aside application.
• You have received a section 79A or section 90SN application and need to respond.
• Your former spouse has become bankrupt or insolvent after orders.
• A creditor is threatening proceedings affecting property covered by the orders.
• You are about to sign a private variation document without further Court orders.
• You have been threatened, coerced or pressured into consenting to orders.
• Family violence is affecting your ability to gather or preserve evidence about the original settlement.

In any of these situations, obtain advice before taking the irreversible step. Combined family-law, commercial, property and litigation experience helps identify the documentary record, the right experts and the right implementation path early — before the options narrow.
