The Inheritance Illusion:Why Having a Will May Not Be Enough
Australia is approaching an extraordinary transfer of wealth. Yet many families remain unprepared for what happens when property, businesses, superannuation and expectations finally change hands.
There is a comforting assumption many Australians make about inheritance.
The family will work it out. The children will be treated fairly. The business will remain in the family. And somewhere, in a filing cabinet or bottom drawer, there is a will that will make everything clear.
Unfortunately, wealth rarely transfers as neatly as people imagine.
Australian household wealth reached approximately $19.2 trillion in the June quarter of 2026. The Productivity Commission has estimated that around $3.5 trillion in assets will transfer between Australian generations by 2050. The wealth will move. The more important question is whether it will pass according to the intentions of the people who built it—or through outdated documents, legislative rules and costly family disputes.
When the law replaces your intentions
Dying without a valid will is known as dying intestate.
When this happens, assets forming part of the estate are distributed under the intestacy laws of the relevant state or territory. In Queensland, an administrator may need to obtain authority from the Supreme Court before managing and distributing the estate. The law follows a prescribed order. It cannot take account of every private promise, family sacrifice or informal understanding. It may not recognise that one child provided years of unpaid care, another received substantial financial assistance during the parent’s lifetime, or a blended family has competing expectations. The outcome may be legally correct while being entirely different from what the deceased—or their family—expected.
Not making an estate-planning decision does not prevent a decision from being made. It simply transfers that power to legislation, trustees or the courts.
A will is not the whole estate plan
Even people with a will may have a false sense of security.
A will generally deals only with assets that legally form part of the estate. Superannuation, jointly owned property, trust assets and some insurance benefits may be handled separately. Superannuation is particularly misunderstood. It does not automatically pass according to the instructions in a will. Depending on the fund rules and nominations in place, the trustee may decide how the death benefit is paid. A binding death benefit nomination can provide greater direction, but nominations must be valid and appropriate for the member’s circumstances. Some expire and need to be renewed, while others may remain in place until revoked. Trusts and companies create further complexity because the underlying assets may not be personally owned. What transfers may instead be control of the structure through trustee, director or shareholder arrangements.
A will is therefore one component of an estate plan—not the entire plan.
The myth of an equal inheritance
Many parents begin with a seemingly straightforward instruction: divide everything equally between the children. Equality feels neutral. But an equal division does not always produce an appropriate or legally secure outcome. Australian succession laws allow certain eligible people to seek further provision from an estate when they believe adequate provision has not been made for their maintenance and support. The rules and eligibility requirements differ between states and territories.
A financially independent adult child may be in a different position from a sibling living with disability, unstable employment or serious financial hardship. A surviving spouse with limited resources may have needs that cannot be addressed through a simple equal division. Estrangement can also complicate matters. A difficult or distant relationship does not necessarily remove every potential claim against an estate. This does not mean people cannot decide how their assets should be distributed. It means that excluding or significantly disadvantaging someone who may have a legitimate claim should be approached with careful legal advice.
A will that appears decisive may still be vulnerable if the broader family circumstances have not been properly considered.
Blended families and competing responsibilities
Modern families frequently include second marriages, de facto partners, children from previous relationships, stepchildren and jointly accumulated assets. A person may want to ensure their current partner can remain financially secure while also preserving an inheritance for children from an earlier relationship.
Achieving both can be difficult.
Leaving everything outright to a surviving partner may mean those assets are later redirected through that person’s own estate. Leaving significant assets immediately to adult children may compromise the partner’s security. Carefully designed arrangements—including testamentary trusts, rights to occupy a home, insurance funding and considered ownership structures—may help balance these responsibilities. But documents alone cannot resolve every tension. Many estate disputes begin with the gap between what different people believed would happen. One child remembers being promised the business. Another expects an equal share. A new spouse assumes they will inherit the home.
The person at the centre of the plan believes everyone understands. Often, nobody does.
When family promises are never documented
Family farms and private businesses create particular risks because much of the family’s wealth may be concentrated in a single asset.
Consider the child who works in a family enterprise for decades, accepts a modest income and gives up other career opportunities after repeatedly being told, “One day, this will all be yours.” If that promise is later changed—or never properly documented—the financial and emotional consequences can be severe. Claims based on promises and detrimental reliance can be complex, expensive and deeply damaging to family relationships. They may also threaten the future of the business itself.
A genuine succession plan should address more than who eventually receives ownership. It should consider who will manage the business, how control will transfer, how the retiring generation will be funded and how family members who do not receive the operating asset will be treated. Decades of contribution should not rest on a casual assurance.
Why an old will may no longer work
A will prepared 10 or 15 years ago may reflect a life that no longer exists.
Since it was signed, the person may have married, separated, divorced, welcomed children or grandchildren, acquired property, sold a business or established a trust. An executor may no longer be suitable. A beneficiary may have died or experienced a major change in circumstances. Asset values may also have altered the practical effect of the instructions.
A property that represented a modest part of the estate when the will was drafted may now be its most valuable asset. A specific gift may have been sold, leaving one beneficiary with significantly less than intended. Estate plans should therefore be reviewed after major life and financial events—and periodically even when nothing dramatic appears to have changed.
The conversation families avoid
The strongest estate plans begin before documents are drafted. They begin with questions.
What is the wealth intended to achieve? Who depends on it? Does anyone actually want to run the family business? Have some children already received significant support? Are there vulnerabilities that require protective structures rather than an outright inheritance?
Parents may avoid these conversations because they fear creating entitlement. Adult children may hesitate because they do not want to appear interested in money. Yet silence allows assumptions to harden. A family conversation does not mean beneficiaries should negotiate their inheritance. It means the principles behind the plan can be explained, incorrect expectations identified and practical issues addressed while there is still time.
The goal is not necessarily agreement. The goal is clarity.
What well-prepared families do differently
Families that transfer wealth successfully tend to act early, review their plans regularly and discuss their intentions deliberately. They also coordinate the professionals involved.
A succession lawyer prepares and tests the legal documents. An accountant considers taxation and business structures. An insurance specialist examines protection and liquidity. A financial adviser brings together the family’s assets, cash flow, structures and long-term objectives. Without coordination, each professional may solve only the part of the problem they can see.
Five questions worth asking now
You should be able to answer these questions with confidence:
Do I have a current and valid will?
Does it align with my superannuation, trusts, insurance and ownership structures?
Have my family or financial circumstances changed?
Would my family understand the principles behind my decisions?
Are my financial adviser, lawyer and accountant working from the same information?
Estate planning is an act of stewardship
Estate planning is often framed as a conversation about death. It is better understood as an act of stewardship during life. It is the process of deciding how your wealth should protect people, preserve opportunities and continue the values that helped create it. A signed will may provide reassurance. A coordinated estate plan provides something more valuable: a greater likelihood that your intentions will survive the realities of law, tax, family relationships and time. Because the greatest threat to a family legacy is not always insufficient wealth.
Sometimes, it is insufficient preparation.
