Rising Sydney Property Prices and the Increase in Family Provision Claims



Sydney property prices have soared in recent years, directly fuelling a notable rise in estate disputes across the region. The dramatic increases in real estate values have made contesting wills and launching family provision claims a viable and attractive option for many potential beneficiaries. Many estate disputes are now being driven by the significant growth in property value in Sydney, as even modest estates with a single residential property can lead to litigation that would not have been practical in the past. Families are finding that what once may have seemed a minor inheritance is now significant, leading to heightened motivation to challenge how estates are distributed.



When Property Values Rise, So Do Estate Disputes


The volume of family provision claims in the NSW Supreme Court is rising, with a growing number of adult children seeking a share of estates. Although these individuals may appear financially stable, factors like high mortgage repayments, inflation, and the cost of living in Sydney often place them under considerable strain, motivating them to pursue claims against family estates. Current NSW law still requires adult children to demonstrate a special present or future need to succeed in a family provision claim, which can include unemployment, illness, or disability, but the threshold is increasingly attainable given today's economic climate. Recent state data indicates that from 2019 to 2023, family provision claims have increased by 10 percent, from 878 to 968 annual cases, highlighting the growing prevalence of these disputes.


The NSW Supreme Court continues to see the majority of estate disputes initiated by adult children, who accounted for over 60 percent of family provision claims in the past year, with spouses and former de facto partners accounting for most of the remaining filings. This pattern demonstrates a deepening trend of intergenerational contest, with adult children often feeling inadequately provided for and motivated by rising Sydney property prices and the broader, unprecedented intergenerational wealth transfer estimated at $5 trillion. This transfer of wealth is driving new complexities and tensions in estate litigation, particularly in situations involving blended families, where obligations to spouses, stepchildren, and children from earlier relationships frequently result in conflicting inheritance expectations.


Academic research further reveals that family provision claims are rarely futile; a substantial 74 percent of such claims achieve a successful outcome, reinforcing the incentive for claimants to challenge wills where there is perceived unfairness. In many cases, claims are resolved through settlement rather than a final decision by the Court, but the trend is clear, rising property values and complex family structures are making disputes more common. Estate planning is crucial in this environment. Clear instructions, properly prepared wills, and careful consideration of family relationships and financial needs are essential for those seeking to minimise disputes and protect their intended wishes.


For those who may be potential beneficiaries, early legal advice is increasingly important. Understanding the viability and proportionality of any possible claim is now an essential step as the Sydney housing market continues to reshape the size and nature of estates. As Sydney property prices continue to rise and the intergenerational wealth transfer gathers pace, estate disputes in NSW and claims in the NSW Supreme Court are only expected to grow. Effective estate planning is the best safeguard against these challenges, offering clarity and protection for both testators and beneficiaries as the landscape evolves.
