Separation does not automatically revoke your ex-spouse’s right to inherit from your estate. Under Australian law, separation alone does not change your Will, your enduring power of attorney, or your appointment of an enduring guardian. Until you finalise a divorce or formally update your estate documents, your separated spouse remains entitled to everything your current Will provides. The separation impact on inheritance is therefore a matter of what you do after you separate, not what the law does automatically. Simons George Legal works with clients across Sydney to address exactly this gap before it becomes a costly problem.
How does separation affect your inheritance rights in Australia?
The distinction between separation and divorce is the most misunderstood point in estate planning. Separation is the act of living apart with the intention of ending a marriage. Divorce is the formal legal termination of that marriage, granted by the Federal Circuit and Family Court of Australia after a 12-month separation period. These are two very different legal events, and the law treats them differently.
Separated spouses remain legal spouses for inheritance purposes until divorce is finalised. That means your ex-partner can still inherit under your Will, act as your executor, and exercise your enduring power of attorney unless you take deliberate steps to change those arrangements.
The risks extend beyond your Will. Non-probate assets, including superannuation and life insurance, are governed by beneficiary designations held by financial institutions. Updating a Will does not affect those designations. Your superannuation fund will pay your death benefit to whoever is named on the nomination form, regardless of what your Will says. The same applies to life insurance policies.
Key documents to review immediately after separation include:
- Your Will. Confirm who inherits and who you have appointed as executor.
- Enduring power of attorney. This gives your attorney broad financial control if you lose capacity.
- Appointment of enduring guardian. This governs medical and lifestyle decisions.
- Superannuation death benefit nominations. Binding nominations lapse every three years unless renewed; non-binding nominations are discretionary.
- Life insurance beneficiary designations. Contact your insurer directly to update these.
Pro Tip: Review all five documents within 30 days of separation. Do not wait until divorce proceedings begin. The gap between separation and divorce can last years, and an outdated estate plan is fully enforceable during that entire period.
What can Australian readers learn from other jurisdictions?
Comparing how other countries handle inheritance after separation reveals just how little protection Australian law currently provides at the point of separation.
Ontario, Canada, made significant changes through its Succession Law Reform Act. Under rules applying to separations from january 2022 onwards, a separated spouse who meets the 3-year separation threshold is treated as though they predeceased the testator. Will gifts and intestate rights are automatically voided once that threshold is met, provided the couple has lived separate and apart with no reasonable prospect of reconciliation. Formal criteria, such as a separation agreement or the passage of three years, must be satisfied. Mere separation is not enough.
In many US states, divorce revokes Will gifts to an ex-spouse by operation of law. However, life insurance and retirement accounts remain payable to named beneficiaries regardless of marital status, because those assets are governed by contracts with financial institutions rather than by the Will. Even in jurisdictions with stronger statutory protections, the non-probate asset problem persists.
| Jurisdiction | Separation effect on Will | Non-probate assets |
|---|---|---|
| Australia | No automatic change | Require separate beneficiary updates |
| Ontario (Canada) | Revoked after 3 years apart (from jan 2022) | Require separate beneficiary updates |
| Many US states | Revoked upon divorce, not separation | Require separate beneficiary updates |
The table makes one point clear. No jurisdiction automatically resolves the non-probate asset problem. Every separated person, regardless of where they live, must contact their financial institutions directly to update beneficiary designations.
For Australians, the lesson is sharper. Australia provides no automatic revocation of Will gifts upon separation. The burden falls entirely on you to act.
Common misconceptions about inheritance after separation
The most dangerous assumption separated people make is that living apart is legally equivalent to being divorced. It is not. Separation does not equate to legal divorce, and inheritance and intestacy rights remain fully intact until the court grants a divorce order.
A second misconception is that updating your Will is sufficient. It is a necessary step, but not a complete one. Naming an ex-spouse as beneficiary on non-probate assets creates ongoing risk even after Will revisions. Direct contact with each financial institution is the only way to change those designations.
A third risk involves family provision claims. Even when an ex-spouse is excluded from a Will, they may still make a claim against the estate under family provision legislation. Family provision claims can override intended estate distributions if not addressed in a binding financial agreement or consent orders. A well-drafted separation agreement reduces but does not eliminate this risk.
Consider this scenario. A person separates, moves out, and assumes their estate is protected because they intend to update their Will eventually. They die before doing so. Their separated spouse inherits the entire estate under the existing Will, acts as executor, and controls the distribution of assets. The children from a previous relationship receive nothing.
Pro Tip: Do not finalise a separation agreement without also reviewing your estate plan. A family lawyer and an estate lawyer should work in parallel, not sequentially. Waiting until property settlement is complete leaves your estate exposed for months or years.
Practical steps to protect your inheritance intentions after separation
Protecting your estate after separation requires a coordinated approach across legal documents and financial accounts. The following steps address the most common gaps.
Update your Will and power of attorney
A new Will is the foundation. It should name a new executor, specify new beneficiaries, and revoke all prior Wills explicitly. Your enduring power of attorney should be revoked and replaced at the same time. Leaving an ex-spouse as your attorney creates serious risk if you lose capacity before divorce is finalised.
Address non-probate assets directly
Contact your superannuation fund and request a new binding death benefit nomination. Check the expiry date on any existing nomination. Contact your life insurer and update the beneficiary on each policy in writing. These steps must be taken separately from any Will update.
Formalise the separation with legal agreements
A binding financial agreement or consent orders through the Family Court can clarify property division and reduce the scope for future estate claims. Separation alone does not close financial claims between spouses. Formalising the separation creates a clear record of each party’s entitlements.
Seek specialist legal advice early
Statutory protections have significant limitations, and relying on them without comprehensive estate updates poses real risk. A wills and estates specialist can identify gaps that a general practitioner may miss. Simons George Legal offers a complimentary 30-minute consultation to assess your situation and recommend practical next steps.
A post-separation estate planning checklist:
- Instruct a solicitor to draft a new Will.
- Revoke and replace your enduring power of attorney.
- Update your appointment of enduring guardian.
- Lodge a new binding death benefit nomination with your superannuation fund.
- Update beneficiary designations on all life insurance policies.
- Review any jointly held assets and consider how they pass on death.
- Obtain legal advice on a binding financial agreement or consent orders.
What happens if you die separated but not divorced in Australia?
Dying separated but not divorced creates one of the most legally complex estate situations in Australian law. Your separated spouse is still your legal spouse. That status carries significant consequences.
If you die without a valid Will, the intestacy provisions of the relevant state Succession Act apply. In New South Wales, the Succession Act 2006 governs intestacy distribution. A surviving spouse, including a separated spouse, receives the statutory legacy and a share of the remainder of the estate. Children from the relationship share the balance. Children from a prior relationship may receive nothing if the separated spouse’s entitlement consumes the estate.
| Situation | Outcome under NSW intestacy |
|---|---|
| Separated, no Will, no children | Separated spouse inherits entire estate |
| Separated, no Will, children of the relationship | Separated spouse receives statutory legacy plus share of remainder |
| Separated, no Will, children from prior relationship | Prior children may receive reduced or no share |
| Separated, valid updated Will | Estate distributed per Will terms |
Even with a valid Will that excludes the separated spouse, a family provision claim remains possible. The separated spouse may apply to the court for a share of the estate on the basis of financial need or past contributions. Courts have discretion to award provision regardless of the Will’s terms.
The risk of an ex-spouse acting as executor is equally serious. An executor controls the administration of the estate, including timing of distributions and management of assets. Removing an ex-spouse from that role requires a new Will. Without one, they retain full authority.

| Act early, not after divorce | The gap between separation and divorce can last years; estate documents should be updated within weeks of separating. |
What I have seen in practice
Separation is a financial and legal identity change, not just a personal one. The clients I see who face the most serious estate problems are those who treated separation as a waiting room for divorce. They assumed the law would protect them in the interim. It does not.
The cases that concern me most involve superannuation. A person can spend months updating their Will and still leave their entire superannuation balance to an ex-partner because they never lodged a new binding nomination. Superannuation is often the largest single asset in an estate. Missing that step can undo everything else.
I also see people underestimate the family provision risk. Even a well-drafted Will can be challenged. A separated spouse who can demonstrate financial need or a history of contribution to the relationship has standing to make a claim. A binding financial agreement, negotiated at the time of separation, is the most effective way to reduce that exposure.
The good news is that the solution is straightforward. Separation triggers a clear checklist of legal tasks. Working through that checklist with a specialist, ideally within the first month of separating, closes the gaps before they become disputes. Estate planning after separation is not about pessimism. It is about making sure your intentions are actually carried out.

FAQ
Does separation automatically change my Will in Australia?
No. Separation does not change your Will, executor appointment, or enduring power of attorney in Australia. You must actively update these documents after separating.
Can my separated spouse still inherit if I die before divorce?
Yes. A separated spouse remains your legal spouse until a divorce order is granted. They retain full inheritance rights under your existing Will and under intestacy laws if you have no valid Will.
Does updating my Will cover my superannuation?
No. Superannuation is a non-probate asset governed by your fund’s trust deed and your beneficiary nomination. Updating a Will does not affect superannuation; you must lodge a new binding death benefit nomination directly with your fund.
Can my ex-spouse make a family provision claim even if excluded from my Will?
Yes. A separated spouse can apply to the court for provision from your estate under family provision legislation, regardless of what your Will says. A binding financial agreement reached at separation reduces but does not eliminate this risk.
How soon after separation should I update my estate plan?
Update your Will, power of attorney, and beneficiary designations within 30 days of separating. The period between separation and divorce can last years, and your existing documents remain fully enforceable throughout that time.
