The Great Wealth Transfer: Rising Inheritance Disputes and the Future of Family Fortunes

Australia is on the cusp of a massive generational wealth transfer, with $5.4 trillion set to pass from the silent generation and baby boomers to their descendants over the next two decades. This “great wealth transfer” is coinciding with increasing complexity in family structures, rising property values, and deepening economic inequality, leading to a surge in disputes over wills, and estates.

The Rise in Inheritance Litigation

Data from New South Wales supreme court reveals a dramatic increase in succession and probate cases. Court-annexed mediations rose from 104 in 2021 to 735 in 2025, whereas filings in succession and probate increased from 1,168 to 1,467 over the same period. While the majority of wills are settled without conflict, the number of contested estates is growing significantly.

Factors Fueling the Disputes

Several factors are contributing to this trend:

• Rising Property Values: Eye-watering house prices are raising the stakes for inheritances, making even relatively compact estates a source of contention.
• Deepening Inequality: In a society where wealth is increasingly concentrated, inheritances are becoming crucial for financial security and homeownership.
• Complex Family Structures: More blended and non-nuclear families are creating ambiguity and potential conflicts regarding inheritance rights.
• Ageing Population: A growing number of individuals are nearing life expectancy with substantial assets accumulated in property and superannuation.
• Inheritance Impatience: A growing expectation of receiving an inheritance, sometimes leading to disputes even over smaller estates.

Legal Challenges and Changing Laws

The legal landscape surrounding inheritance is evolving. Family provision legislation, originally designed to protect widows and children, has expanded to include stepchildren in some jurisdictions, such as South Australia. This expansion allows more individuals to challenge wills they deem unfair.

Courts balance testamentary freedom – the right to choose who inherits property – with a moral responsibility to provide for family and dependents. However, there are now repercussions for bringing frivolous claims, including potential cost-capping and the possibility that estates will not cover legal fees.

New Challenges in the Digital Age

Technology is introducing new complexities. Text messages and digital notes are increasingly being used as evidence of a deceased person’s intentions. The rise of AI-generated wills also raises concerns about accurately assessing mental capacity and independence during the will-making process.

The Emotional Toll of Inheritance Disputes

Inheritance disputes are rarely about the money alone. They often stem from deeper issues of recognition, hurt, and unfinished family business. As Prue Vines, a law professor at the University of New South Wales, notes, these cases are often “a grief process layered with conflict.” Family relationships can be irreparably damaged by these disputes.

Preventing Inheritance Conflicts

Experts recommend proactive estate planning and open communication within families. “Pre-planning” – tidying up estates well before death – and “post-planning” – preparing affairs for afterwards – are becoming increasingly common. Clear expectations and intentions, discussed while alive, can help prevent misunderstandings and disputes.

Family meetings, facilitated by legal professionals, can help explain that an inheritance is not a fixed entitlement. Understanding that a will is often just the “opening move” in a complex process can encourage more realistic expectations.
