Settling an inheritance dispute out of court means using alternative dispute resolution methods, primarily mediation and negotiation, to reach a binding agreement without a judge deciding the outcome. 85–90% of inheritance disputes in Australia settle before trial through these methods. That figure holds across NSW, Victoria, and Western Australia. The financial case is equally clear: court proceedings can cost each party $50,000 to $200,000 or more, while mediation typically costs a fraction of that. Simons George Legal helps families across Sydney resolve these disputes efficiently, with clear advice tailored to their circumstances.
How to settle an inheritance dispute out of court: what you need first
Before mediation can begin, you need to confirm you have standing to bring a claim. In Australia, family provision claims are governed by state legislation, such as the Succession Act 2006 (NSW) or the Administration and Probate Act 1958 (Vic). Eligible claimants generally include spouses, children, and dependants who were not adequately provided for in the will.
Time limits are strict and vary by state. In NSW, you have 12 months from the date of death to file a family provision claim. In Victoria, the limit is six months from the grant of probate. Missing these deadlines can end your claim before it starts, so getting legal advice early is not optional.
Gathering the right documents before mediation gives you a real advantage. A well-prepared claimant moves faster, negotiates from a position of knowledge, and avoids costly delays. Your documentation checklist should include:
- The original will and any earlier versions
- The grant of probate or letters of administration
- A full inventory of estate assets and liabilities, including property valuations
- Your own financial records, including income, expenses, and assets
- Any correspondence with the executor or other beneficiaries
- Medical or dependency records if your claim relies on a care relationship
Pro Tip: Organise your documents into a single folder before your first legal meeting. Mediators and solicitors work faster when the facts are clear, and that speed saves you money.
Legal advice before mediation is not just helpful. It is the difference between knowing your rights and guessing at them. A solicitor can assess the strength of your claim, advise on realistic outcomes, and help you set a negotiating position before you sit down with the other side.
How does the mediation process work for inheritance disputes?
Mediation is a structured negotiation facilitated by a neutral third party. The mediator does not decide who wins. Their job is to help both sides communicate, identify common ground, and reach a voluntary agreement. Most inheritance mediations resolve in a single day, compared to court proceedings that can run for 12–18 months or longer.
The process typically follows these steps:
- Initiate contact. Write to the executor or their solicitor to propose mediation. If the other side refuses, a court can order mediation as part of pre-trial directions.
- Appoint a mediator. Choose an accredited mediator with experience in estate disputes. Both parties must agree on the appointment.
- Exchange position statements. Each party prepares a brief written summary of their claim and desired outcome. This is shared before the session.
- Attend the mediation session. The mediator opens with a joint discussion, then moves parties into separate rooms for private caucuses. This allows frank conversations without direct confrontation.
- Negotiate toward agreement. The mediator shuttles between rooms, testing proposals and narrowing differences. Most sessions produce a heads of agreement signed on the day.
- Formalise the settlement. A solicitor converts the heads of agreement into a binding deed of settlement or consent orders filed with the court.
Courts now routinely refer inheritance disputes to mediation before any hearing takes place. Judges and registrars actively encourage early settlement. This means mediation is not a soft option. It is the standard first step in the Australian dispute resolution process.
The entire process from initiating contact to signed settlement typically takes 6–9 months. That timeline accounts for document preparation, scheduling, and the drafting of final agreements.
Pro Tip: Engage a solicitor to send the initial mediation proposal. A formal letter from a lawyer signals that you are serious and often prompts the other side to respond constructively.
All discussions in mediation are confidential and conducted on a “without prejudice” basis. Nothing said during the session can be used as evidence in court if mediation fails. That protection encourages honest negotiation.
What are the costs of settling an inheritance dispute out of court?
The cost difference between mediation and litigation is significant. Mediation costs typically range from $3,000 to $15,000, shared between the parties. Supreme Court trials cost $50,000 to $200,000 or more per party. Those figures do not include the emotional toll or the time lost.
| Method | Typical cost range | Timeline | Control over outcome |
|---|---|---|---|
| Mediation | $3,000–$15,000 shared | 6–9 months | High: parties decide |
| Supreme Court trial | $50,000–$200,000+ per party | 12–18+ months | Low: judge decides |
The true measure of success in an inheritance dispute is the net amount you receive after legal fees. A larger court award that costs $150,000 to obtain may leave you worse off than a mediated settlement reached for $10,000.
Rejecting a reasonable settlement offer carries real financial risk. If a party declines a written offer and the court later awards the same or less, the rejecting party may be ordered to pay the other side’s legal costs from the date of the offer. These written offers, known as Calderbank letters, are a standard tool in estate litigation and can shift the entire cost burden of a case.
Understanding cost consequences of refusing reasonable offers is one of the most important pieces of financial knowledge you can have before entering negotiations. A solicitor can advise you on whether an offer you have received is genuinely reasonable, or whether holding out is justified.
Mediation fees are usually split equally between parties, though this is negotiable. Each party pays their own legal fees for preparation and attendance. Some solicitors offer fixed-fee mediation packages, which makes budgeting easier.
What strategies help achieve a durable out-of-court settlement?
The most durable settlements go beyond simple cash transfers. Mediation enables creative solutions that a judge cannot impose, and that flexibility is one of its greatest strengths. A court can only redistribute money. Mediation can redistribute relationships, objects, and time.
Practical strategies that produce lasting agreements include:
- Creative asset distribution. Instead of forcing a sale of the family home, one beneficiary might receive the property while others receive superannuation proceeds, shares, or other assets of equivalent value.
- Structured payment plans. If the estate lacks liquid assets, a beneficiary can agree to receive their share in instalments over an agreed period, avoiding a forced property sale.
- Transfer of sentimental items. Agreements can include non-financial terms such as the transfer of heirlooms, jewellery, or personal effects that hold meaning beyond their monetary value.
- Apologies and acknowledgements. Some disputes are driven as much by hurt feelings as by financial need. A formal acknowledgement of a claimant’s contribution to the deceased’s life can be part of a settlement deed.
- Timeline agreements. Parties can agree on when assets will be transferred, giving executors time to manage the estate without pressure.
Maintaining respectful communication throughout is not just good manners. It is a negotiating asset. Parties who treat each other with basic dignity reach agreement faster and produce settlements that hold. Hostility entrenches positions and drives up costs.
Common pitfalls to avoid include making ultimatums early in the process, sharing confidential mediation discussions with other family members, and letting social media become a record of the dispute.

When is mediation not suitable for resolving inheritance issues?
Mediation works best when all parties are willing to negotiate in good faith and the facts of the estate are not seriously disputed. Mediation is unsuitable where there are serious allegations of fraud, undue influence, or significant power imbalances between parties. These issues require a court to make findings of fact.
Situations where mediation is unlikely to succeed or is inappropriate include:
- Allegations that the will was forged or that the testator lacked mental capacity
- Claims that a beneficiary exerted undue influence over the deceased
- One party refusing to disclose assets or financial information
- A significant power imbalance, such as a legally represented party negotiating against an unrepresented one
- A party who is not engaging in good faith and is using mediation to delay proceedings
If mediation fails or is refused, the next step is filing a claim in the relevant court. In NSW, family provision claims are heard in the Supreme Court. The court will then manage the matter through directions hearings, and mediation may still be ordered at a later stage.
Pro Tip: Get legal advice before agreeing to mediate. A solicitor can assess whether the other side is likely to engage genuinely, and whether the facts of your case are better suited to a court determination.
Knowing when not to mediate is as important as knowing how to mediate. If the dispute involves conduct that needs to be exposed and sanctioned, a court is the right forum. For a broader overview of your dispute resolution options in NSW, Simons George Legal has published a detailed 2026 guide.

What I’ve learned from watching families navigate inheritance disputes
After working in wills and estates for years, the pattern I see most often is this: families who engage early and with realistic expectations almost always reach a better outcome than those who dig in and wait for a court date.
The emotional pull toward litigation is understandable. When you feel wronged by a will, a courtroom can feel like the only place where justice is possible. But courts do not deliver justice in the way people imagine. They deliver a judgment, and that judgment is shaped by evidence, legal tests, and the discretion of a single judge. The outcome is rarely what either side expected.
Mediation, by contrast, gives you control. You decide what you will accept. You decide what you will offer. And because the process is confidential, you can have honest conversations that would be impossible in open court. I have seen siblings reach agreements that preserved their relationship precisely because mediation gave them a private space to say things they could not say in a courtroom.
My honest advice: set a realistic financial goal before you start. Know what you need, not just what you want. And get legal advice early, not after you have already said things in writing that close off options. The families who do that consistently reach better settlements, faster, and with less damage to the relationships that matter.
