What Are Inheritance Disputes in Australia?

Inheritance disputes (also called estate disputes or will disputes) occur when family members, partners or other eligible people disagree about how a deceased person’s assets should be divided. Assets include homes, superannuation, shares, bank accounts and personal items.

In Australia, these disputes are governed by state laws. In NSW, most are handled in the Supreme Court under the Succession Act 2006. Common triggers include unclear wills, perceived unfairness, or challenges to the will’s validity.

Understanding the process early can save tens of thousands in legal fees and months (or years) of stress.

Common Causes of Inheritance Disputes in Australia

Most will disputes Australia stem from these key issues:

• Ambiguous or poorly drafted wills – Vague wording leads to different interpretations.

• Family provision claims – Eligible family members (spouse, de facto, child, grandchild, dependent) believe they were not adequately provided for.

• Blended families & second marriages – Step-children vs biological children conflicts.

• Undue influence or lack of capacity – Claims the will-maker was pressured or lacked mental capacity.

• Outdated wills – Not updated after marriage, divorce, birth of children or major asset changes.

• Superannuation & binding death benefit nominations – Often paid outside the will and cause surprise disputes.

• Executor delays or lack of transparency.

  
  

Recognising these red flags early helps families act before emotions escalate.

The Importance of a Clear Will in Australia – Prevention Starts Here

A professionally drafted will is the #1 way to minimise inheritance disputes. Here’s how to create one that stands up in court:

1. Use plain English – avoid legal jargon that confuses family members.

2. Be specific about gifts, beneficiaries and percentages.

3. Include a “no-contest” clause where appropriate (though not always enforceable).

4. Update regularly – review after every major life event.

5. Get it signed and witnessed correctly (two independent witnesses).

6. Consider a testamentary trust for asset protection and tax benefits.

7. Work with an experienced estate planning lawyer (not a cheap online template).

   
   

Pro tip: Separate superannuation from your will with a binding death benefit nomination – this can avoid many family fights.

Family Provision Claims in Australia (The Most Common Dispute)

Under Australian law, certain family members can apply for a family provision order if they feel the will did not make “adequate provision” for their proper maintenance and support.

• Who can claim? Spouses, de facto partners, children (including adult children), grandchildren in some cases, and dependents.

• Time limits (NSW): Usually 12 months from the date of death.

• What the court considers: Financial needs, relationship with deceased, size of estate, and the deceased’s moral duty.

  
  

Success rates for family provision claims are high (over 70% settle or succeed), which is why early legal advice is critical.

Mediation as the Best Way to Resolve Inheritance Disputes

Over 90% of estate disputes in Australia now resolve through mediation – far cheaper and faster than court.

Benefits of mediation for inheritance disputes:

• Costs 10–20% of court fees

• Usually resolved in 1–3 sessions (weeks, not years)

• Confidential and private

• Preserves family relationships

• Court-annexed mediation is common in NSW Supreme Court

  
  

Many specialist estate lawyers offer early mediation services before proceedings even start. It’s often the smartest first step.

The Role of the Estate Executor in Australia

The executor (or administrator if no will) has serious legal duties and can become the target of disputes if not handled well:

• Obtain probate (or letters of administration)

• Compile a full inventory of assets

• Pay debts, taxes and funeral expenses first

• Keep detailed records and communicate regularly with beneficiaries

• Distribute assets according to the will (or intestacy rules)

  
  

Transparent executors who communicate early prevent most misunderstandings.

Legal Options When Mediation Fails

If mediation doesn’t work, these are the main pathways:

• Probate Court proceedings – challenging validity of the will

• Family provision applications – seeking more from the estate

• Trust disputes (if assets are in a family trust)

• Formal settlement agreements – binding deeds of family arrangement

  
  

Going to court should be the last resort – costs can easily exceed $100,000–$500,000 per side.

Proven Strategies to Prevent Future Inheritance Disputes

The best defence is proactive planning:

• Hold family meetings to explain your estate plan while you’re alive

• Write a letter of wishes explaining why you made certain decisions

• Use equal vs needs-based distribution thoughtfully

• Put assets into discretionary testamentary trusts

• Update wills and binding nominations every 2–3 years

• Document everything – conversations, reasons, and changes

  
  

Open communication is the #1 factor in preventing family fights over inheritance.

The Emotional Toll of Inheritance Disputes & How to Cope

Inheritance disputes don’t just drain bank accounts – they destroy families. Grief plus money creates toxic stress, anxiety, depression and permanent rifts.

Healthy coping strategies:

• Seek counselling or a grief therapist specialising in estate conflicts

• Focus on shared memories rather than assets

• Practise empathy – everyone is grieving differently

• Set boundaries and use a neutral mediator early

  
  

Remember: no amount of money is worth losing your family.
