W v S [No 3] [2026] WASCA 136
The Western Australian Court of Appeal has set aside final property settlement orders made by consent in de facto relationship proceedings after finding that a case guardian had failed to comply with the requirements of Rule 109(d) of the Family Court Rules 2021 (WA). The Court held that the obligation to provide affidavit evidence establishing that proposed consent orders are in a party’s best interests is a fundamental safeguard for people with a disability, rather than a mere procedural formality. A finding that the orders were just and equitable was insufficient to satisfy this separate requirement. The decision highlights the responsibilities of case guardians, the importance of expressly addressing a represented party’s best interests and the limits of judicial discretion to dispense with procedural rules designed to protect vulnerable litigants.
