Estrangement is painful enough on its own. When a family member dies and the will reveals you’ve been left out, the grief and confusion compound quickly. Many people assume that estranged family member inheritance rights simply don’t exist. That assumption is wrong, and acting on it could cost you everything. Under New South Wales law, estrangement does not automatically strip you of the right to make a claim on an estate. What it does do is complicate the process in ways that reward preparation and punish delay.

Inheritance rights for estranged family members in NSW
The starting point that surprises most people: estrangement does not automatically prevent an inheritance claim. The obligation to provide for certain family members can persist despite years of separation. NSW courts do not treat estrangement as an automatic disqualifier. They treat it as a factor to be weighed.
The legal framework that governs these situations is the Succession Act 2006 (NSW). Under Part 3.2 of that Act, eligible persons can apply for a family provision order if they believe adequate provision has not been made for them from a deceased person’s estate. Eligible persons include spouses, de facto partners, children (including adult children), former spouses, and certain other dependants or household members.
The key categories most relevant to estranged relatives are:
- Adult children who have been excluded from a will or received a smaller share than expected
- Siblings and other relatives who may qualify if they were dependent on the deceased
- Estranged spouses or former partners who may retain rights depending on the circumstances
Inheritance laws for estranged family members in NSW do not require you to have had a close or recent relationship with the deceased. What they require is that you fall within an eligible category and that the court finds adequate provision was not made for your proper maintenance, education, or advancement in life.
One critical point on timing: claims must be filed in the Supreme Court of NSW within 12 months of the date of death. Missing that window generally bars your claim unless the court grants special leave, which is uncommon and difficult to obtain.

Pro Tip: If you are unsure whether you qualify as an eligible person under the Succession Act, seek legal advice immediately after the death, not after the estate has been distributed.
Preparing your claim as an estranged family member
Preparation is where most claims are won or lost before they ever reach a courtroom. Documentation of relationship history, reconciliation attempts, and financial need significantly aids family provision claims. Courts weigh this evidence heavily when estrangement is in dispute.
Here is what you need to gather before filing:
- Evidence of your relationship with the deceased. This includes letters, emails, text messages, photographs, and records of any contact, no matter how intermittent. If you attempted to reconcile, document those attempts specifically.
- Reasons for the estrangement. Courts examine whether the deceased contributed to or caused the breakdown of the relationship. If the estrangement was driven by the deceased’s behaviour, that matters to your claim.
- Your current financial circumstances. Provide bank statements, tax returns, evidence of debts, housing costs, and any medical or care needs. Courts need a clear picture of why the estate provision (or lack of it) leaves you inadequately provided for.
- Contributions you made to the deceased’s estate. If you provided care, financial support, or labour that benefited the deceased’s assets, document it. This strengthens the moral obligation argument.
- A copy of the will and details of the estate. You are entitled to request a copy of the will from the executor. Understanding the full estate value and how it has been distributed helps frame your claim accurately.
Understanding the executor’s role is also worth knowing. Notification of probate proceedings is required for all heirs-at-law, including estranged children. If you were not properly notified, that may itself provide grounds to challenge the administration of the estate.
Pro Tip: Start gathering evidence the moment you learn of the death. Memories fade, digital records get deleted, and executors can move quickly to distribute assets once probate is granted.

Filing a family provision claim and contesting the will
Once you have your evidence together, the formal process begins. You file an application in the Supreme Court of NSW, and the matter proceeds through a structured legal process that can involve mediation, negotiation, or a full hearing.
Courts assessing estranged relatives inheritance claims look at a specific set of factors:
- The duration and depth of the estrangement
- Who caused or contributed to the breakdown of the relationship
- Whether any genuine attempts at reconciliation were made by either party
- The claimant’s current financial need and competing claims from other beneficiaries
- The size and nature of the estate
The court applies what is known as the “judicious parent” standard. It asks what a wise and just parent, aware of all the circumstances, would have provided. This is not a simple test, and the outcome is not guaranteed.
A useful comparison shows how different estrangement scenarios affect claim prospects:
| Scenario | Effect on claim |
|---|---|
| Estrangement caused primarily by the deceased | Strengthens moral obligation argument for the claimant |
| Estrangement caused by the claimant’s conduct | Reduces but does not eliminate claim prospects |
| Sporadic contact maintained | May help, but superficial contact alone does not maintain a moral claim if no meaningful relationship existed |
| No contact for many years, claimant’s choice | Significantly weakens claim; court may find moral obligation extinguished |
| Documented reconciliation attempts | Materially improves prospects regardless of who caused the estrangement |
One important nuance: a parent can only effectively disinherit an adult child with explicit and valid testamentary documents. Simply leaving someone out of a will without clear reasons can create ambiguity that courts may interpret as accidental omission rather than deliberate exclusion. If the deceased left a statement of reasons for excluding you, the court will consider those reasons and assess whether they were based on accurate facts or misunderstandings.
It is also worth noting that an estranged child’s financial need alone does not guarantee success. Courts balance financial need against the quality of the relationship, the moral obligation owed, and competing claims from other family members such as a surviving spouse or dependent children.

After filing: what to expect and next steps
Filing your claim is not the end of the process. It is the beginning of a phase that requires patience, flexibility, and continued legal support.
Key things to understand once your claim is lodged:
- The executor must be served. Once you file, the executor and all beneficiaries named in the will must be formally notified of your application.
- Mediation is common. Most family provision claims in NSW are resolved through mediation before reaching a full hearing. This is generally faster, cheaper, and less adversarial than a court battle.
- Settlement is a real option. Many estranged relatives inheritance claims settle for a negotiated sum that reflects a compromise between the claimant’s needs and the interests of other beneficiaries.
- Legal costs are a real consideration. If your claim succeeds, costs may be paid from the estate. If it fails, you may be liable for your own costs and potentially the other side’s. Understand this risk before proceeding.
- Appeals are possible but costly. If the court’s decision is unfavourable, you can appeal, but appeals are expensive and rarely succeed without a clear legal error in the original decision.
The inheritance disputes process in NSW can feel overwhelming, particularly when it overlaps with grief and fractured family relationships. Having a lawyer who understands both the legal and human dimensions makes a material difference to how you experience and navigate the process.
My honest take on estrangement and inheritance claims
I’ve seen too many people walk into these situations with one of two mistaken beliefs: either that estrangement means they have no rights at all, or that financial need alone will carry their claim. Neither is true, and both lead to poor decisions.
What I’ve learned from working through these matters is that the courts are genuinely trying to do something fair. They are not looking to punish estrangement, but they are not going to ignore it either. The quality and honesty of the evidence you bring matters enormously. A claimant who can demonstrate they tried to repair the relationship, even if those attempts failed, is in a far stronger position than one who cannot.
The other thing I’d say plainly: timing is unforgiving. The 12-month deadline is real, and the courts are not sympathetic to people who delayed because they were grieving or hoped the situation would resolve itself. If you think you have a claim, act now. Get advice this week, not next month.
One more uncomfortable truth. Court decisions like Cusack v. Cusack show that renewed estrangement caused by an adult child’s own choices can reduce or extinguish the moral claim entirely. The law is not automatically on your side just because you are family. You have to make the case.

FAQ
Can an estranged family member inherit under NSW law?
Yes. Estrangement does not automatically prevent a family member from making a family provision claim under the NSW Succession Act 2006. The court considers the reasons for and duration of estrangement as factors, not as automatic bars.
How long do you have to contest a will in NSW?
Family provision claims must be filed in the Supreme Court of NSW within 12 months of the date of death. Extensions are rarely granted and require special leave from the court.
What does the court consider in an estranged family member estate claim?
Courts assess the duration and cause of estrangement, attempts at reconciliation, the claimant’s financial need, the size of the estate, and competing claims from other beneficiaries. Financial need alone is not sufficient.
Can a parent legally disinherit an estranged adult child in NSW?
A parent can attempt to disinherit an adult child, but only with clear and valid testamentary documents. Even then, the adult child may still make a family provision claim, and the court will assess whether the disinheritance was justified based on accurate facts.
What evidence helps an estranged relative’s inheritance claim?
Documented evidence of the relationship history, financial need, reconciliation attempts, and any contributions made to the deceased’s estate all strengthen a family provision claim significantly.
