Full Court Appeal Property Contributions Spousal Maintenance Unacceptable Risk Artificial Intelligence

The Full Court set aside property and spousal maintenance orders because the trial judge left a material dispute about the wife’s inheritances unresolved and never determined her claim for ongoing maintenance, while upholding a change of residence for the two younger children.

“

“The failure of the primary judge to resolve the factual controversy, or to provide reasons explaining how those matters featured in the contribution-based assessment, constituted House v The King error.”

Summary

The parties began living together in about 2002, married in 2004 and separated in July 2024, after a relationship of some 22 years. They have three children together. Following a five-day final hearing in March 2026, the primary judge ordered that the two younger children, who had not seen their father in 16 months, since November 2024, live with him, with the eldest remaining with the mother. On property, his Honour found a net pool of $978,993, assessed contributions as equal, made a 5% adjustment in the wife’s favour and declared the parties jointly and severally liable for a judgment debt of about $857,671 secured by a writ over the former matrimonial home. The wife, self-represented on appeal, challenged both the parenting and property orders.

The Full Court allowed the property appeal on two grounds. The evidence about the wife’s initial contributions and inheritances was in clear conflict, ranging from about $613,000 on the husband’s own affidavit to nearly $1 million on the wife’s account, yet the primary judge recorded the competing versions without resolving them or explaining why findings could not be made. Applying Greer & Mackintosh and Storie v Storie, the Court held that this was an error of law and a House v The King error ([45]–[49]). The wife’s claim for ongoing spousal maintenance had also been raised and joined but never determined, which the husband’s solicitor conceded was an error ([51]–[53]). The parenting appeal was dismissed: having found that the mother posed an unacceptable risk through coaching and alienation that could not be ameliorated while the children remained in her care, the primary judge was not required to consider alternatives that no party had proposed ([68]–[71]).

The decision is a reminder that a judgment which merely recites competing assertions on a material contributions issue is exposed on appeal, and that key claims squarely raised must be determined, if only by dismissal with reasons. It also contains the Full Court’s pointed observations on self-represented parties using artificial intelligence to prepare appeal documents. While there is no prohibition on its use, the Court observed that such documents too often contain non-existent or irrelevant legal propositions, cases that do not exist or do not support the proposition cited, and language so confused that it obscures any real error, describing the appellant’s material as a salutary example ([30]–[32]).

The property proceedings were remitted for rehearing, with the balance of the sale proceeds preserved on trust in the meantime.

Key Takeaways

✓
Resolve contested contributions evidence. Set out initial contributions and inheritances with documentary support and a clear chronology to help the Court make findings; the Court observed that the evidence here “ought to have been clearly set out” and was not.
✓
Every key claim must be determined. Where spousal maintenance or other relief is sought, support it with submissions and a minute of order so the Court has what it needs to decide it; an unaddressed claim may be an error of law.
✓
Approach artificial intelligence with care. The Full Court warned that AI-assisted appeal documents often give only an illusory appearance of legal argument and can obscure genuine error.
