Just read Farrah & Cisek [2024].

The de facto wife claimed family violence in her testimony. No other evidence is noted by the court. The court made a distribution of 100% of the de facto husband's property (about $1,350,000 AUD) on the basis that her non-financial contributions to the marriage were made significantly harder due to the violence she alleges. The de facto husband's appeal was dismissed.

Throughout her relationship with the de facto husband the de facto wife was married to another man.
