Why Inheritance Disputes Are Rising in Australia, and What You Can Do About It

You’ve spent decades building wealth. You’ve made decisions, taken risks, worked hard. And now you’re thinking about what happens when you’re gone.

But here’s what most people don’t realise: the very things that made you successful, the property portfolio, the family business, the trust structures, the second marriage, are the same things that can tear your family apart after you die.

Inheritance disputes in Australia aren’t just increasing. They’re exploding. Court filings are up 40% in some states. Mediation lists are backed up for months. And the disputes aren’t just about money. They’re about hurt, betrayal, and families who never speak again.

This isn’t media hype. It’s a measurable trend driven by real structural forces: unprecedented property wealth, aging demographics, blended families, and asset structures that don’t align with family expectations.

If you have significant assets, property, business interests, superannuation, trusts, you need to understand why this is happening and what you can do now to keep your family out of court.

The Numbers Tell a Clear Story

Let’s start with the data, because it’s striking.

In New South Wales, contested estate filings have climbed steadily over the past five years. Queensland reports similar patterns. Mediation services specifically for inheritance disputes are reporting case loads they’ve never seen before.

A 40% spike in will disputes isn’t a blip. It’s a structural shift.

And it’s happening against the backdrop of what demographers call the “great wealth transfer”, an estimated $3.5 trillion passing from Baby Boomers to the next generation over the next two decades. Most of that wealth is tied up in residential property that has appreciated dramatically over 30 to 40 years.

Your parents bought a house in the 1980s for $150,000. It’s now worth $2 million. When they die, that house, and the debate over who gets what share of it, becomes the centre of a family dispute that no one saw coming.

Can you clearly explain to each of your children why you’ve structured your estate the way you have?

If you can, you’re ahead of most families. If you can’t, that’s the gap where disputes grow.

What These Disputes Actually Look Like

Inheritance disputes fall into a few common patterns. Recognising them helps you spot the risk in your own situation.

Being excluded from a will entirely. Adult children discover they’ve been left out. Sometimes it’s deliberate, a breakdown in the relationship, years of estrangement. Sometimes it’s an outdated will that was never updated after a reconciliation or a new marriage. Either way, the excluded person often has legal standing to make a claim.

Arguing the will doesn’t make adequate provision. Even if you’re in the will, you can challenge it on the basis that it doesn’t properly provide for you. This is a family provision claim. It’s not about what the deceased wanted. It’s about whether the court thinks the will is fair given your relationship and needs. Spouses, de facto partners, children, and in some cases stepchildren or dependants can bring these claims.

Questioning whether the will is valid. Disputes over the deceased’s mental capacity at the time they signed the will. Allegations of undue influence, someone pressuring an elderly parent into changing their will. Challenges to the formalities: was it properly witnessed, was there fraud, was there a later will that revokes this one?

Disputes over assets that sit outside the will. Superannuation death benefits don’t automatically follow your will. Neither do assets held in discretionary trusts or family companies. If your super goes to one child under a binding nomination, but your will says it should be split equally, you’ve just created a dispute. Same with the family business held in a trust, who controls it, and does that align with what you intended?

Executor disputes. The person you’ve appointed to administer your estate is in conflict with beneficiaries, or isn’t acting, or is accused of favouring one side. Executor disputes can be just as bitter and expensive as disputes over the will itself.

You see the pattern: these disputes happen when expectations, legal documents, and asset structures don’t line up.

The Pressure Points: Why Now, Why So Many

So why is this happening now, and why is it getting worse?

Property Wealth and Generational Inequality

The biggest driver is property. Australian residential real estate has appreciated faster and further than almost any asset class over the past 30 years. If you bought your home in the 1980s or 1990s, you’re sitting on wealth you didn’t necessarily expect.

Your children, on the other hand, are facing a housing market where median prices in capital cities are ten or twelve times median incomes. Many of them can’t afford to buy without help. And they know, everyone knows, that a significant portion of their lifetime wealth is going to come from inheritance.

That creates pressure. Expectations are higher. The financial stakes are higher. And when the will doesn’t meet those expectations, the sense of injustice is sharper.

Blended Families and Second Marriages

This is the other major structural shift. More Australians are entering second or third relationships later in life. You remarry at 60. You have adult children from your first marriage. Your new spouse has their own children.

You want to provide for your spouse, of course you do. But you also want your children to inherit the family home, or the business, or the portfolio you built over decades.

Here’s the tension: your spouse expects security, a place to live, financial support for potentially another 20 or 30 years. Your children expect to inherit what they see as “family” assets, especially if they watched you build the wealth during your first marriage.

If your will says “everything to my spouse”, your children may feel shut out. If your will tries to balance things with a life interest or a right to reside, your spouse may feel like a tenant in their own home, and your children may resent waiting.

Blended families are a predictable flashpoint. And the law doesn’t solve this tension for you. It just gives both sides a pathway to fight about it.

The Cost of Living and “Inheritance Impatience”

There’s a more uncomfortable dynamic at play, too. Adult children are struggling with cost of living, housing affordability, and wage stagnation. Some are looking at their aging parents’ wealth and thinking, “I need that now, not in 20 years.”

It’s uncomfortable to name, but it’s real. Some disputes are driven by what’s been called “inheritance impatience”, adult children who feel entitled to access wealth earlier, who resent spending on aged care or lifestyle, who start positioning themselves for a larger share while the parent is still alive.

That impatience creates conflict during life and litigation after death.

Complexity of Modern Asset Structures

Finally, there’s complexity. Most successful families don’t just own a house and a bank account. You have a family trust. Maybe a self-managed super fund. Perhaps a private company that holds the business or investment properties. Maybe a partnership or shareholder arrangement with other families.

Each of these structures has its own rules about what happens on death. Discretionary trusts don’t pass under a will, control passes according to the trust deed. Superannuation is governed by separate rules and binding nominations. Company shares might be subject to buy-sell agreements.

If you haven’t lined all of this up, you’ve created a dispute waiting to happen. Because your family will assume everything flows according to your will, and then discover, often after you’re gone, that half the wealth is outside the will and subject to different rules.

Can you sit down right now and draw a diagram showing who controls each asset and structure after you die?

If you can’t, that’s a red flag.

How Business and Trust Structures Amplify the Risk

Let’s talk about what makes disputes even more complicated for families with real assets: the structures you’ve used to build and protect your wealth.

If you’re a business owner, you’ve probably set up a discretionary trust to hold trading income or investment property. You might have a private company as trustee, or as the operating entity. You’ve almost certainly got a self-managed super fund with significant balances.

These structures are great for tax, asset protection, and flexibility during your life. But they’re a nightmare for inheritance if you don’t plan properly.

Discretionary Trusts and Control

A discretionary trust doesn’t have “owners” in the way a house does. It has a trustee (often a company you control), beneficiaries (usually a wide class including family members), and an appointor (the person who can remove and replace the trustee, the real power).

When you die, the trust doesn’t end. The assets don’t flow into your estate. What passes is control.

If your will says your three children inherit equally, but the trust deed says the appointor role passes to your spouse, or to your eldest child, you’ve just created a fight. Because whoever controls the appointor role controls the trust, and the trust might hold the bulk of the family wealth.

I’ve seen families where siblings spent years and hundreds of thousands of dollars fighting over who should be appointor of the family trust, because that’s where the real money is.

Superannuation and Binding Nominations

Superannuation is another trap. It sits outside your estate unless you deliberately direct it there. If you have a binding death benefit nomination directing your super to your spouse, that’s where it goes, even if your will says something different.

Scenario: your will splits everything equally between your spouse and your two children. But your $2 million super balance has a binding nomination to your spouse. Your children get half the estate minus the super. Your spouse gets half the estate plus all the super. That’s not equal. That’s a dispute.

Or worse: you have no binding nomination. Your super fund trustee has discretion. They decide based on who they think is most deserving or most dependent. Your children might get nothing. Or your new spouse might get nothing. Either way, litigation.

Family Businesses and Operating Entities

If the family business is held in a trust or a company, the succession question isn’t just “who inherits the shares?” It’s “who controls the business, and how do we treat children who aren’t involved in it?”

You have three children. One has worked in the business for 20 years. The other two have their own careers. Do you split ownership equally? That creates tension, the active child resents sharing control with siblings who’ve contributed nothing. Do you give the business to the active child and other assets to the others? That only works if you have enough other assets to balance things, and even then, the non-active children may resent it.

If you haven’t thought through the governance, the buy-sell arrangements, and the fairness question, the business becomes a litigation target the moment you die.

What You Can Do Now to Reduce the Risk

Right. Let’s talk about what you actually do to avoid leaving your family in a mess.

Get a Current, Proper Will

Obvious, but not universal. If you don’t have a will, intestacy laws decide who gets what, and I promise you the default rules won’t match what you intended. If your will is 15 years old and hasn’t been reviewed since your second marriage, or since you set up the family trust, or since your youngest child turned 18, it’s out of date.

Get a will. Make sure it’s current. Make sure it’s drafted by someone who understands your structures, not just a basic template.

Align Your Will with Your Structures

This is the big one. Your will deals with your estate, the assets you own personally. But if most of your wealth is in a trust, a company, or super, your will might be almost irrelevant.

You need to align everything:

• Who is the appointor or successor trustee of your family trust after you die?
• Do you have binding death benefit nominations for all your super, and do they align with your will?
• If you have a company, who inherits the shares, and is there a shareholders’ agreement that overrides your will?
• If you have life insurance held outside super, who is the beneficiary?

This isn’t a “set and forget” exercise. Every time you set up a new structure or change a significant asset, you need to revisit the alignment.

Document Your Intentions, Especially for Unequal Gifts

If you’re not splitting things equally, you need to explain why. Not in the will itself, that can be challenged. But in a separate letter or statutory declaration, signed at the same time as the will, setting out your reasons.

“I am leaving the business to my daughter Emily because she has worked in it for 20 years and built it with me. I am leaving equivalent value in property to my son Michael. This reflects their different contributions and ensures fairness.”

Or: “I am leaving a larger share to my son David because he has been my primary carer for the past five years, and I want to recognise that contribution.”

Courts take these explanations seriously. And more importantly, your family takes them seriously. A clear, contemporaneous explanation reduces the emotional drive to litigate.

Choose Your Executor Carefully

Your executor is the person who administers your estate, deals with lawyers, manages disputes, and distributes assets. Don’t just pick your eldest child because they’re the eldest. Pick someone who is organised, impartial, and capable of handling conflict.

In complex estates, consider appointing a professional executor (a trustee company or a lawyer) alongside a family member. Yes, it costs more. But it also reduces the risk that your executor becomes the target of a dispute, or that family conflict paralyses the administration.

Get Capacity Evidence If You’re Older or Unwell

If you’re over 75, or if you have any cognitive decline, get a capacity assessment from a doctor when you sign your will. It’s a short report confirming that you understood what you were doing, that you weren’t under pressure, and that you had capacity.

This is especially important if you’re making a will that’s different from an earlier one, or if you’re in a new relationship, or if there’s any chance someone will later argue you were influenced or coerced.

The cost of a capacity report is a few hundred dollars. The cost of a will dispute over capacity is tens or hundreds of thousands.

Think About Timing and Communication

Here’s the hard question: do you tell your family what’s in your will, or do you let them find out after you die?

There’s no one right answer. But I can tell you that disputes are more common when the will comes as a complete surprise.

If your will is going to create hurt or confusion, consider having a conversation while you’re still here to explain it. Not a family meeting where you hand out copies of the will, that’s too formal and too fraught. But a conversation where you explain your thinking.

“I’ve set things up so that the family home provides for your stepmother for her lifetime, and then it passes to you and your brother. I know that might feel like a long wait, but I need to make sure she’s looked after, and this is the fairest way to do it.”

It won’t remove all the tension. But it removes the shock, and it removes the sense that you didn’t care enough to explain.

Managing the Inheritance Conversation Without Destroying Relationships

Let’s be honest: talking about your death and your money with your family is uncomfortable. For everyone.

But avoiding the conversation doesn’t make it easier. It just stores up the conflict and pain for after you’re gone, when you’re not there to explain, mediate, or clarify.

The data shows that very few Australian families have open conversations about estate planning. And there’s a direct correlation between that silence and the rate of disputes.

So how do you have the conversation without it turning into a disaster?

Start with Why, Not What

Don’t lead with the numbers. Don’t say “here’s how much you’re getting.”

Start with why you’re having the conversation. “I want to make sure that when I’m gone, you understand my decisions and you’re not left wondering what I intended.”

Frame it as giving them clarity and reducing future stress, not as dividing up the spoils.

Be Clear About Your Priorities

Tell them what’s important to you. “My priority is making sure your stepmother is secure for the rest of her life. After that, I want the family home to stay in the family.” Or: “The business goes to your sister because she’s the one who’s built it with me, but I want to make sure you all benefit from the wealth we’ve created.”

When people understand your priorities, they’re more likely to accept decisions that might otherwise feel unfair.

You Don’t Have to Share Every Detail

You can have the conversation without reading out your will line by line. You’re giving them the shape of your thinking, not a binding contract.

“I’ve set up my estate so that you’re all treated fairly, but fair doesn’t always mean equal. Emily is getting the business. You two are getting property and other assets. The overall value should balance out, and I’ve worked with my advisers to make sure of that.”

Manage Expectations Early

If someone is going to be disappointed, it’s better they know that now than after you’ve died. Not every conversation will be pleasant. But an uncomfortable conversation while you’re alive is far better than a legal fight when you’re gone.

Revisit It Over Time

Estate planning isn’t a one-off conversation. Your family changes. Relationships shift. Someone gets divorced, someone has a health crisis, someone does something that makes you rethink your plans.

If you change your will significantly, consider having another conversation to explain why.

If a Dispute Starts: What Happens and How to Approach It Sensibly

Let’s say you’re on the other side now. Someone has died, and you’re unhappy with the will. Or you’re the executor and someone is threatening to challenge the estate. What actually happens?

Time Is Critical

Family provision claims, where you’re arguing the will doesn’t adequately provide for you, are subject to strict time limits. In most states, you have somewhere between six and twelve months from the date of death to file. Miss the deadline and you’re out, unless you can get an extension (which is hard).

If you think you have a claim, don’t wait. Get legal advice within the first few months, not in month eleven.

Most Disputes Settle Before Trial

Here’s what most people don’t realise: inheritance disputes almost never go to trial. The vast majority settle, either in direct negotiation or in court-ordered mediation.

Why? Because trials are expensive, slow, and unpredictable. Even if you have a strong case, the cost of running it to trial might eat 20% or 30% of the estate. Courts know this, which is why they now routinely refer contested estates to mediation early in the process.

Mediation means sitting down with the other side, a neutral mediator, and trying to find a resolution everyone can live with. It’s not about proving you’re right. It’s about finding a deal that avoids the cost and destruction of a trial.

A Sensible Approach Means Knowing What You’re Really Fighting For

Before you start a dispute, or before you dig in as an executor, ask yourself: what does a good outcome actually look like?

Is it about the money, or is it about being heard and respected? Is it about fairness, or is it about punishing someone you’re angry with?

If you can separate the emotional drive from the practical goal, you’re much more likely to settle sensibly.

I’ve seen people spend $150,000 in legal costs to secure an extra $80,000 from an estate. That’s not a win. That’s ego and hurt masquerading as principle.

What the Court Actually Considers in Family Provision Claims

If your case does go to court, the judge will consider several factors:

• Your relationship with the deceased and the nature of that relationship
• Your financial position and needs
• The size of the estate and the competing claims on it
• Any contributions you made to the deceased’s welfare or property
• Whether the deceased had any moral obligation to provide for you
• Any relevant conduct, yours or the deceased’s

The court has broad discretion. “Fair” doesn’t mean equal. It means adequate provision given all the circumstances.

The Role of the Executor

If you’re the executor, your job is to administer the estate according to the will, but also to act in the interests of the estate as a whole. You’re not there to “win” for one side.

If someone makes a reasonable claim, it’s often sensible to negotiate rather than fight. Don’t burn through estate assets on legal fees out of stubbornness.

When to Get Advice, and What to Ask For

Estate planning isn’t something you do once and forget. It’s an ongoing process that should be reviewed every few years, and every time something significant changes in your life or your structures.

Don’t Wait Until You’re Unwell

One of the biggest mistakes people make is putting off estate planning until they’re in poor health or cognitive decline. By that point, it’s harder to get clear capacity evidence, and any changes you make are more vulnerable to challenge.

Get your estate planning done while you’re healthy, clear-headed, and not under pressure.

Involve the Right Advisers

Estate planning sits at the intersection of law, tax, and family dynamics. You need advisers who understand all three.

Your accountant can tell you how to structure things for tax. Your financial adviser can tell you how to align your super and insurance. Your lawyer can draft the documents and explain what happens in disputes.

But someone needs to bring all of that together and make sure it aligns. Often, that’s your lawyer, but don’t assume they’re talking to your accountant. Make sure you’re coordinating the advice.

What to Ask Your Lawyer

When you sit down with your lawyer to review your estate plan, these are the questions to ask:

• Does my will cover everything I own, or are there assets and structures outside it?
• Who controls my trust and my super after I die, and does that align with my will?
• If someone challenges my will, what are the likely grounds and how strong are they?
• Have I documented my reasons for any unequal treatment?
• Is there anything about my family situation or asset structure that creates obvious dispute risk?
• What would a dispute over my estate actually cost, and how long would it take?

A good lawyer will walk you through those questions and give you clear, practical answers.

Review Regularly

Every three to five years, sit down and review everything. And review immediately after:

• Marriage or divorce
• The birth or adoption of a child
• A significant change in your wealth or assets
• Setting up a new trust, company, or super fund
• A major change in your relationship with a family member
• A significant change in your health

Final Thoughts: Clarity Is the Best Protection

Inheritance disputes are rising because families are more complex, estates are larger, and structures are more sophisticated. That’s not going to change.

But disputes aren’t inevitable. They’re the result of poor planning, misaligned documents, and families who never had the hard conversations.

You can’t control everything. You can’t guarantee your family won’t fight after you’re gone. But you can give them clarity. You can explain your thinking. You can align your structures with your intentions. And you can remove the gaps that turn confusion into conflict.

Litigation is expensive, slow, and destructive. It tears families apart and consumes the wealth you spent a lifetime building.

The best protection against that isn’t a clever legal strategy. It’s clarity, transparency, and the willingness to do the hard planning work while you’re still here to do it.

If you’re reading this and you know your estate planning is out of date, or your structures don’t align, or your family has no idea what you intend, don’t wait. The cost of getting it right now is a fraction of the cost your family will pay if you get it wrong.
