Shinohara v Shinohara — The End of Addbacks in Family Law Property Settlements

The Full Court’s decision in Shinohara v Shinohara represents the first authoritative appellate interpretation of the Family Law Amendment Act 2024 provisions, which took effect on 10 June 2025. The Court has held that the practice of “addbacks” - notionally restoring spent funds or dissipated assets into the divisible property pool - is no longer available. Instead, only existing legal and equitable interests in property may be identified and divided at Step 1 of the property settlement process.

What does this mean for clients and practitioners?

The Upshot

The Full Court made several important rulings. First, it confirmed that addbacks cannot form part of the asset pool at Step 1. The only property that may be identified for division is that which legally or equitably exists at the time of trial. Secondly, the Court clarified that while past disposals or dissipations of property cannot be notionally restored, they remain relevant under the statutory framework - they may be addressed as contributions under s 79(4) or as part of the just and equitable considerations under s 79(5). Thirdly, the Court emphasised procedural fairness, finding that it was unfair for the trial judge to remove agreed addbacks from the balance sheet without giving the parties notice or an opportunity to respond. Finally, when the Court re-exercised discretion on appeal, it recalculated the division of assets, awarding 67.5% to the wife and 32.5% to the husband, this time without addbacks in the pool.

Policy and Legal Significance

The decision in Shinohara is significant because it reshapes how courts and practitioners conceptualise the property pool in family law. By making it clear that only existing legal and equitable interests can be included at Step 1, the Full Court has provided certainty about what constitutes the divisible pool. This narrower interpretation eliminates the artificial practice of adding back funds or assets that no longer exist, thereby bringing the identification stage into closer alignment with the statutory text of the Family Law Act.

At the same time, the judgment shifts the real contest in property matters to the later stages of the analysis. Without the convenience of a mechanical “addback,” practitioners must now address dissipation and disposal through the contribution provisions of s 79(4) and the just and equitable considerations under s 79(5). This ensures that arguments are framed in terms of fairness, conduct, and context, rather than being reduced to a balance-sheet exercise. In this way, the decision refocuses attention on the substantive equities of the case, but also increases the discretionary burden on judges, as outcomes will depend more heavily on the individual circumstances and the persuasiveness of the parties’ evidence.

Advantages of the Shinohara Approach

One clear advantage of the Court’s approach is that it restores conceptual clarity. The property pool now strictly reflects what exists at the time of trial, avoiding the artificial exercise of inflating balance sheets with assets that have already disappeared. This simplification provides greater transparency to both parties and ensures that Step 1 is carried out consistently with the statutory wording. The approach also aligns more faithfully with Parliament’s reforms, ensuring that the courts give effect to legislative intent.

Another strength lies in reducing the complexity of balance sheets. Without addbacks, lawyers and judges no longer need to debate hypothetical valuations of spent assets, which often produced both technical disputes and unpredictable results. Instead, attention is redirected to the broader principles of fairness embedded in s 79(4) and (5). This has the potential to produce outcomes that are more substantively just, as the court’s focus shifts away from arithmetic precision toward the actual contributions and circumstances of the parties.

Disadvantages and Risks

The most immediate disadvantage is the risk that the decision creates perverse incentives. A party who dissipates assets may now feel emboldened by the knowledge that those assets cannot simply be notionally added back into the pool. Although wastage arguments remain available, they are harder to establish and more uncertain in outcome. This shift potentially weakens an important safeguard against misconduct.

The evidentiary burden is also heavier under the new regime. Parties will now be required to produce detailed records showing how funds were used if they wish to argue that dissipation should affect contributions or adjustments. Many separating couples do not maintain such records, leaving one party at risk of under-compensation. Relatedly, the emphasis on discretion introduces greater unpredictability. Without the “mechanical repair” of addbacks, outcomes will depend more heavily on the judicial officer’s evaluation of fairness, increasing variability between cases.

Finally, there is the problem of transitional fairness. Cases argued under the expectation of addbacks may need to be recalibrated or even re-litigated. This creates uncertainty for parties already in the system and risks undermining confidence in the consistency of the family law process.

Strategic Considerations for Practitioners

The abolition of addbacks will require a shift in litigation strategy. Practitioners must now be more vigilant about dissipation risks and seek injunctions or freezing orders at an early stage to prevent assets from disappearing before trial. Evidence will need to be gathered and preserved meticulously, with detailed tracing of how funds were spent to support wastage or contribution claims.

Negotiation dynamics will also change. Where one party previously relied on addbacks to strengthen their bargaining position, that leverage is no longer available. Settlement discussions must instead focus on how dissipated assets will be characterised within contributions or adjustments. Counsel must ensure submissions are framed accordingly, pressing for fair recognition of dissipation at Step 2 or Step 3 of the process, rather than seeking to inflate the pool.

Broader Critique

The abolition of addbacks removes a once-staple corrective mechanism in family law. On one hand, this enforces doctrinal rigour and prevents artificial “balance sheet inflation.” On the other, it risks leaving misconduct under-compensated, especially where dissipation is difficult to prove or quantify. Ultimately, Shinohara trades the certainty of arithmetic for the flexibility of discretion - a move that may enhance fairness in principle, but could undermine it in practice.

Conclusion

Shinohara v Shinohara is a watershed decision: addbacks are dead, discretion lives on. The case compels practitioners to shift strategies, focus on evidence of conduct, and be vigilant against dissipation. Whether this results in more just and equitable outcomes, or simply greater unpredictability, will depend on how rigorously courts apply wastage principles under ss 79(4) and (5).
