Background
Anne McFarlane, aged 88, owns a property in Bronte that has been in her family for generations. Annabel McFarlane, aged 56 and Anne’s daughter-in-law, has lived in the main house with her children for seven years, while Anne occupies a granny flat on the property. Anne, seeking to fund her purchase of a retirement village unit, initiated proceedings to recover possession so she could sell the property. Annabel resisted, claiming that in a 2012 family meeting, Anne promised that she and Warick (Anne’s son and Annabel’s then-husband) could live in the property for life and that Anne would bequeath it to them in her will. Anne offered Annabel an alternative: Anne would purchase a separate residence for Annabel and her children to occupy rent-free until the youngest child turned 23, with all expenses covered. Annabel rejected this offer and pursued her estoppel claim.
The case required the court to apply the proprietary estoppel framework recently confirmed in Kramer v Stone (2024), which requires establishment of: (1) a clear and unequivocal promise; (2) reasonable expectation of reliance; (3) actual reliance; (4) detriment; and (5) proportionality of any relief granted. Critically, the alleged promise involved a statement of testamentary intention—that Anne would leave the property to Annabel and Warick—which courts scrutinize with particular care.
The court heard evidence from Annabel, who testified about the family meeting and subsequent statements by Anne allegedly confirming the promise. Anne did not give oral evidence beyond documentary proof. Mark McFarlane, Anne’s son, testified for the plaintiff. The court also considered evidence of extensive renovation work performed on the property from 2013 to 2018, which Annabel claimed demonstrated her reliance on Anne’s promise.
The Court’s Holding
Justice Cavanagh held that Annabel failed to establish the proprietary estoppel upon which she relied. The court found that while Anne may have made statements about the property’s future, these statements did not meet the threshold of a “clear and unequivocal” promise as required by law. The alleged promise was encumbered by several defects: it involved testamentary intention (a bequest in a will), which courts recognize as inherently revocable; it contained elements of ambiguity about conditions and circumstances; and prior inconsistent statements made by Anne to other family members undermined its clarity. The court emphasized that statements of testamentary intention require extraordinary clarity and evidence that they were understood to be irrevocable, not merely expressions of present intention that could change.
The court further found that even if a promise had been made, Annabel had not sufficiently established the degree of reliance and detriment necessary to trigger equitable intervention. While Annabel performed work during renovations and lived in the property, these acts were not shown to be solely or primarily motivated by reliance on an irrevocable promise to inherit the property. The court noted that family members had offered Annabel housing support throughout the relevant period, and the circumstances—including Warick’s estrangement from Anne and the family dynamics—were not consistent with a clear, irrevocable family bargain. Additionally, granting Annabel the relief she sought (permanent occupation and inheritance) would be disproportionate when Anne’s alternative offer provided for Annabel’s housing security and the property’s sale was necessary to fund Anne’s retirement.
Key Takeaways
- Proprietary estoppel claims involving promises about wills or inheritance require exceptionally clear and unequivocal language; ambiguity or informality defeats the claim even within families.
- Testamentary promises are held to a higher standard because wills are inherently revocable—courts require evidence the promisor intended the promise to be binding and irrevocable, not merely a statement of current intention.
- Reliance must be shown to be genuine and material; acts that might have occurred anyway (or were induced by other family support) do not suffice.
- Courts assess detriment broadly, including countervailing benefits, and will decline to grant disproportionate relief—especially when the promisor offers reasonable alternative accommodation.
- In family disputes, oral promises to convey property are viewed with skepticism; consistency over time and absence of conflicting statements are important to establishing clarity.
Why It Matters
This decision reaffirms that Australian courts will not override property rights based on vague or informal family promises, even where decades of cohabitation and joint investment in the property have occurred. The ruling protects elderly property owners’ ability to sell their assets for retirement security, while cautioning adult children and in-laws not to rely on unwritten family assurances about inheritance without clear, documented agreements. It also signals that judges applying Kramer v Stone will scrutinize testamentary promises rigorously: the mere fact that someone lived rent-free on a property and performed work during renovations will not, standing alone, establish an estoppel to inherit that property.
For family law practitioners and estate planners, the judgment underscores the importance of documenting property arrangements in writing, recording any testamentary intention in a formal will, and clarifying conditions and expectations upfront. The case also demonstrates that courts will not compel a property owner to forgo retirement security to fund the indefinite housing of a family member, even one who has endured domestic hardship, if reasonable alternative arrangements are available.
