Estate & Inheritance Dispute Mediation in Australia — Resolve Without Destroying the Family

Estate disputes — contested wills, family provision claims, executor conflicts, and superannuation disagreements — are on the rise across Australia. Mediation resolves most of them in a single session, without the years and legal costs of Supreme Court litigation, and with far less damage to the family relationships that survive the estate.

Key takeaway: Estate and inheritance disputes — contested wills, family provision claims, executor conflicts, and superannuation disagreements — can almost always be resolved through mediation faster, more cheaply, and with far less lasting damage to family relationships than Supreme Court litigation. Most estate mediations resolve in a single session, with the full process from consultation to signed settlement deed typically taking 4–8 weeks.

Why Estate Disputes Are Rising in Australia

An ageing population, rising property values, blended families, and increasingly complex financial arrangements — including superannuation, self-managed super funds, and family trusts — are creating more contested estates than any previous generation has seen in Australia. The Australian Institute of Family Studies has documented increasing rates of family breakdown and reconstituted families, both of which correlate with more complex estate planning and a higher incidence of contested claims.

When a dispute emerges over how an estate is to be distributed — or whether a will is valid at all — grief can quickly transform into something harder and colder: litigation. Courts take years. Legal fees can consume a significant portion of the estate being fought over. And by the time a matter reaches judgment, the family relationships it was fought over are often beyond repair.

Mediation offers a better way. It is faster, cheaper, private, and — crucially — it allows the family to reach a resolution on their own terms rather than having a court impose one.

Types of Estate and Inheritance Disputes

Estate disputes in Australia typically fall into several categories, each with its own legal framework and practical dynamics.

Dispute typeCore questionGoverning law
Family provision claimWas the applicant adequately provided for?State/territory succession legislation
Contested will (validity)Was the will validly executed?State/territory Wills Acts
Executor disputeIs the executor managing the estate properly?State Supreme Court jurisdiction
Superannuation death benefitWho receives the super: estate or dependant?Superannuation Industry (Supervision) Act 1993 (Cth)
Trust disputeHow should trust assets be distributed or managed?State trust legislation + trust deed

Family Provision Claims

Family provision claims are the most common form of estate litigation in Australia. Every state and territory has legislation allowing eligible persons to apply to a court for provision — or additional provision — from an estate if they have not been adequately provided for. Eligible applicants generally include spouses, de facto partners, children (including adult children), and in some jurisdictions other dependants. The court assesses what "adequate provision" looks like having regard to the applicant’s financial circumstances, the size of the estate, and the nature of the relationship with the deceased.

Courts have discretion to extend time limits in appropriate cases, but do not assume an extension will be granted. If you are considering a claim, seek legal advice and initiate mediation promptly. The Federal Circuit and Family Court of Australia has well-established practices of referring estate and family provision matters to mediation before hearing — in many jurisdictions, mediation is effectively required before the matter proceeds to trial.

Time limits apply. Early mediation gives you the best chance of a full resolution.

Contested Wills

A will can be contested on a number of grounds: lack of testamentary capacity, undue influence, fraudulent execution, failure to comply with formal requirements, or suspicious circumstances surrounding execution. Contested will matters are heard in the Supreme Court of the relevant state or territory. They are complex, expensive, and slow. They are also, in most cases, capable of resolution through mediation — particularly where the underlying dispute is about fairness or family dynamics rather than a genuine legal defect in the document.

Mediation in a contested will matter allows the family to reach a negotiated outcome — typically a re-division of the estate — that avoids the winner-takes-all risk of a court judgment.

Executor Disputes

Disputes over the conduct of an executor arise more often than many families expect. Common sources of conflict include delay in administering the estate, alleged mismanagement of assets, failure to provide proper accounts to beneficiaries, or self-dealing. While these matters can be brought before the relevant state Supreme Court, mediation is frequently more appropriate — it allows the parties to address the underlying concerns directly, agree on a process for the estate’s administration, and preserve the family relationship without the cost and delay of formal proceedings.

Executor disputes benefit from early intervention. A mediator can get the estate moving.

Superannuation Death Benefit Disputes

Superannuation does not automatically form part of a deceased person’s estate. The trustee of the superannuation fund has a legal discretion to pay the death benefit to an eligible dependant or to the estate — unless a valid binding death benefit nomination (BDBN) directs the payment. Where a nomination is absent, has lapsed, or is disputed, conflicts between family members can become significant — particularly where the superannuation balance is substantial.

Common disputes arise between a surviving spouse and adult children from a prior relationship, multiple dependants with competing claims, or where the validity of a BDBN is in doubt. These disputes can be referred to the Australian Financial Complaints Authority (AFCA). Mediation — either through AFCA or privately — is frequently used to resolve them before escalation. The Australian Institute of Family Studies has documented the growing complexity of superannuation in family estates, particularly as super balances have grown significantly over recent decades.

How Estate Mediation Works

Estate mediation follows the same core process as other forms of mediation — a neutral, accredited mediator facilitates structured negotiation between the parties — but with some features specific to estate matters.

Before the session

Each party typically prepares a brief position statement covering their claim, the key issues in dispute, and what resolution would look like for them. The mediator may hold individual intake calls to understand the dynamics. Basic disclosure of the estate’s composition — asset values, liabilities, what has already been distributed — is usually exchanged before the session.

The session

Estate mediation is typically a full-day session (6.5 hours), though simpler matters may resolve in a half day (3.5 hours). Sessions can be conducted in person or online, and shuttle mediation — where the parties remain in separate rooms — is common where emotions are running high or the relationship is strained.

After the session

Where the parties reach agreement, the mediator records the terms in a Heads of Agreement, signed by all parties at the close of the session. This is then used by the parties’ lawyers to draft a binding Settlement Deed. The full process from initial consultation to signed Settlement Deed typically takes 4–8 weeks.

Most estate disputes resolve in a single session. Ours is designed around that outcome.

The Attorney-General's Dept — Family Dispute Resolution has long encouraged mediation as a first step in resolving family disputes — including estate matters — before resorting to litigation.

Costs and Timeframes

Session typePer personTotal (2 parties)
Half day (3.5 hours)$1,500 + GST$3,000 + GST
Full day (6.5 hours)$2,250 + GST$4,500 + GST

Most estate disputes involve at least a full-day session. Complex matters — multiple parties, significant asset pools, or both a family provision claim and a contested will — may require two sessions. A free initial consultation helps determine the likely session structure before you commit.

Each party also typically incurs legal costs for reviewing the Heads of Agreement and drafting the Settlement Deed — usually $1,500–$4,000 per side depending on complexity. Compare this with Supreme Court litigation, where each side’s legal costs for a contested family provision matter routinely reach $30,000–$100,000+, costs taken directly from the estate itself.

When Is Mediation Not Suitable?

Mediation is appropriate for most estate disputes. There are some circumstances where it may not be the right first step: where urgent court orders are needed to protect assets being dissipated; where the dispute involves alleged fraud, forgery, or elder abuse requiring investigation; where a party lacks capacity to participate; or where one party refuses to engage at all. A free initial consultation will give you an honest assessment of whether mediation is appropriate for your matter.

Getting Started

The process begins with a free initial consultation. We discuss the nature of the dispute, what you are hoping to achieve, whether mediation is the right process, and how to approach the other party about participating. There is no commitment required at the consultation stage.

Estate disputes are sensitive. They involve grief, family history, and relationships that extend beyond the dispute itself. Our mediators are experienced in navigating that complexity — bringing the focus back to what a fair resolution looks like, and helping families get there.

Questions & answers

Frequently asked questions

What types of estate disputes can be resolved through mediation?+

Most estate disputes are suitable for mediation, including family provision claims, contested wills (on grounds of capacity, undue influence or formal defects), executor disputes, superannuation death benefit conflicts, and disagreements about how estate assets should be valued or distributed. Mediation is less suitable where urgent court orders are needed to protect assets or where one party refuses to participate.

Is mediation compulsory before going to court over an estate dispute?+

Not legally compulsory in most jurisdictions, but courts increasingly expect parties to have attempted mediation before a contested hearing. In NSW, QLD and VIC, Supreme Courts regularly refer family provision and estate matters to mediation before they are set down for trial. Proceeding straight to court without attempting mediation can result in adverse cost orders.

How long does estate mediation take?+

The mediation session itself is typically a full day (6.5 hours). The full process — from initial consultation to signed Settlement Deed — typically takes 4–8 weeks. Compare this with 12–36 months or more for a contested Supreme Court matter.

How much does estate mediation cost?+

A full-day session costs $4,500 + GST total, typically shared equally at $2,250 + GST per person. A half-day session is $3,000 + GST total ($1,500 + GST per person). Each party also incurs their own legal costs for reviewing the Heads of Agreement and preparing the Settlement Deed. The initial consultation is free.

What happens if we reach agreement at mediation?+

The mediator records the agreed terms in a Heads of Agreement — a written document signed by all parties at the end of the session. Each party then instructs their solicitor to prepare a binding Settlement Deed based on those terms.

Can estate mediation happen online?+

Yes. Estate mediation can be conducted entirely online via secure video conference. Shuttle mediation — where parties remain in separate rooms and the mediator moves between them — is also available both in person and online.

What if one party won’t agree to mediation?+

Mediation requires voluntary participation. However, courts can order mediation in certain circumstances, and a refusal to mediate can be taken into account in costs orders. A letter from a solicitor proposing mediation often changes the dynamic. We can advise on this in a free initial consultation.

Does the mediator give legal advice during the session?+

No. The mediator is neutral and does not give legal advice to any party. Their role is to facilitate negotiation and help the parties reach their own agreement. Each party should have access to their own legal advice — particularly for reviewing the Heads of Agreement before signing.
