Jennifer Williamson: Blended families driving surge in estate disputes as Australians fail to update their wills

Brisbane solicitor Jennifer Williamson, principal and founder of Williamson and Associates, is warning that the rapid rise of so-called 'Brady Bunch' families is creating significant estate planning havoc, with more than half of Australians failing to update their Wills after major life changes.

With blended families now a common feature of modern Australia, Jennifer says outdated Wills are becoming one of the leading causes of family conflict after death.

"The structure of families has changed dramatically over the past few decades," Jennifer said.

"We now regularly see second marriages, long-term de facto relationships, stepchildren, children from previous relationships and shared assets across multiple households. Yet many people are still relying on Wills drafted 10, 20 or even 30 years ago."

She said this disconnect is fueling a sharp increase in estate disputes.

"I am seeing a dramatic rise in contested estates because people are not updating their Wills," she said.

"When a Will does not reflect a new partner, new children, changed financial circumstances or altered family relationships, it creates uncertainty, resentment and often litigation."

The hidden risks of blended family estates

Jennifer explained that blended families introduce legal complexity that requires careful and deliberate planning.

In many cases, individuals assume their intentions are obvious. They believe their spouse will do the right thing or that children will sort it out. However, when relationships are layered and loyalties divided, assumptions can quickly unravel.

"If your Will does not clearly outline how assets are to be distributed between a current partner and children from previous relationships, you are effectively leaving behind a blueprint for conflict," Jennifer said.

She noted that superannuation, jointly owned property and informal financial arrangements often complicate matters further. When documentation has not been reviewed or aligned, the estate outcome may be very different from what the deceased intended.

The emotional and financial cost

Jennifer said the consequences are not just legal, they are deeply personal.

"Disputes over estates fracture families permanently," she said.

"I have seen siblings stop speaking, stepfamilies torn apart and significant portions of estates consumed by legal costs that could have been avoided with proper planning."

She emphasised that when a Will is outdated or unclear, the law may step in to determine how assets are distributed, and that outcome rarely aligns perfectly with the deceased's wishes.

Why people avoid updating their Wills

Despite the risks, Jennifer said many people delay updating their estate planning documents because they find the subject uncomfortable or assume their earlier documents remain valid.

"Life changes quickly," she said.

"Relationships end, new partnerships begin, children are born, businesses evolve and assets grow or diminish. Estate planning should evolve alongside those changes."

In blended family situations particularly, she warned that failing to review a Will after remarriage or entering a new long-term relationship can create unintended legal consequences.

A call for proactive planning

Jennifer is urging Australians, particularly those in second marriages or blended family arrangements, to review their estate planning as a matter of urgency.

"Estate planning is not a one-off task," she said.

"It should be reviewed regularly and immediately after any significant life event. The cost of updating a Will is minimal compared to the cost of a family dispute."

With more complex family dynamics becoming the norm, Jennifer said clear, professionally drafted estate documents are essential to protecting both relationships and legacies.

"The greatest gift you can leave your family is clarity," she said.

"Without it, you may leave behind uncertainty, division and unnecessary legal battles."
