Case Summary
FCFCOA (Division 1), First Instance•Stewart J•28 July 2026
A s 90C financial agreement never became operative because no separation declaration was ever made, and the husband’s death could not engage the Pt VIIIA machinery either.
It follows that, at the time of the husband’s death, the financial agreement had not become operative in the manner necessary to affect the wife’s present claims. The agreement may have had contractual form, but in the respects presently relied upon it depended upon the statutory machinery of Pt VIIIA of the Act. That statutory machinery was not engaged.
Stewart J at [41]
The wife married the husband in April 1996; they never divorced and he died in 2021 aged 87. The estate is worth roughly $1,650,000 with a self-managed superannuation fund estimated at about $4,000,000, and Supreme Court of South Australia proceedings are on foot in which the wife has claimed further provision under the Inheritance (Family Provision) Act 1972 (SA). Standing in her way was a s 90C financial agreement signed on 15 July 2008, at a point when she had filed, and a fortnight later discontinued, proceedings for spousal maintenance and property adjustment. Recital D recorded separation under one roof in December 2007; Recital E immediately recorded a mutual wish to explore reconciliation. The wife sought a declaration that the 2008 agreement was of no force and effect.
The evidence was effectively unchallenged: the wife was also the estate’s legal personal representative, and the husband’s grandson discontinued his opposition at the final hearing. Stewart J accepted that the parties reconciled and lived as husband and wife until the husband’s death. They acquired three overseas properties in joint names between 2010 and 2018, he made a new will in 2017 naming her executor, and she cared for him through the year of illness before he died. No separation declaration was ever made.
Section 90DA(1) renders those provisions of a financial agreement dealing with property on breakdown of the marriage of no force or effect until a separation declaration is made, and, as the High Court held in R Lawyers v Mr Daily [2025] HCA 41, no such declaration can be made until the parties have separated. Because ‘breakdown’ is defined in s 4 to exclude breakdown by reason of death, the husband’s death could not engage the machinery either. The alternative contractual and equitable arguments of rescission, abandonment and termination were left undecided.
