When a relationship ends, most people focus on the immediate financial questions: who keeps the house, how the superannuation is divided, and what happens to joint accounts. What often falls through the cracks is estate planning. Your will, superannuation beneficiary nominations, and life insurance policy may still name your ex-spouse as the primary beneficiary, and in some situations, that does not change automatically when you separate.
Does separation automatically change your will?
No. Separation alone does not revoke or alter a will in Australia. Divorce is different. Under the Wills Act (and equivalent state legislation), a divorce generally revokes any gifts to a former spouse and their appointment as executor. But separation without a divorce order leaves your existing will intact. If you die during the period between separating and finalising your divorce, your estranged spouse may still be entitled to receive what your will specifies.
This gap can last years. Property settlements often take 12 months or longer to resolve, and many couples wait the full 12-month separation period before applying for divorce at all. That is a substantial window of exposure.
What to update immediately after separation
Three documents need attention quickly. Most people tackle only one of them.
First, your will itself. Book an appointment with a solicitor as soon as practicable after separation and have a new will drafted. A handwritten amendment to an existing will carries serious legal risk and will likely not hold up. A properly executed new will replaces the old one entirely.
Second, your superannuation beneficiary nominations. Superannuation does not automatically form part of your estate; it sits outside the will. Your fund pays the death benefit according to the nomination on file, not your will. If your nomination is still in your ex-spouse's name, your fund may pay out to them regardless of what your will says. Check whether your nomination is binding or non-binding, because the rules differ. A binding nomination is locked in for 3 years from the date it's signed unless your fund has a different arrangement. Update it now rather than assuming the divorce process will prompt a reminder.
Third, life insurance and income protection policies. The beneficiary listed on these policies also operates independently of your will. Contact your insurer directly and request a change of beneficiary form. Keep a copy of the completed form and confirm the change has been recorded.
Enduring powers of attorney and medical directives
These documents are just as important and just as overlooked. An enduring power of attorney authorises a nominated person to make financial and legal decisions on your behalf if you lose capacity. If your ex-spouse holds that power and you have not revoked it, they retain that authority even after separation.
Revocation must be done in writing and in accordance with your state's legislation. Simply telling them verbally that you're revoking the power is not sufficient. Your solicitor can prepare the revocation document at the same time as your new will, which keeps the process efficient.
A medical or advance care directive, sometimes called an enduring guardianship, similarly needs review. These documents appoint someone to make health decisions for you if you can't. Separation is a legal event, not an automatic trigger for revoking these appointments.
The interaction with property settlement
Estate planning after separation does not sit in isolation. It connects directly to what you own and what you're entitled to receive through the settlement process. As part of a property settlement, the asset pool is assessed and divided. Until that process is finalised, the value of your estate is in flux. Your will should reflect that uncertainty.
One practical approach: have your solicitor draft a will that accounts for the possibility that the settlement is still underway. This might mean specifying that gifts to your children are conditional on assets being transferred to you, or that certain property is only gifted if it forms part of your estate at the date of death. A family lawyer and an estate planning solicitor can coordinate on this.
If your separation involves a business, the picture gets more complex. The value of that business, who owns it, and what happens to it in the settlement will all affect what ends up in your estate. It's worth getting clarity on those questions as part of the broader process.
What happens if you die without updating your estate documents
The consequences depend on what documents you have in place and how they are structured. If you die intestate (without a valid will), each state has a formula for distributing your estate. In most Australian states, an estranged spouse who has not yet legally divorced you may still be treated as a spouse under that formula and receive a significant portion of the estate.
If you have an outdated will, your estate goes through probate as normal, and the gifts in that will are honoured unless the document is successfully challenged. A separated spouse is entitled to contest the will in most jurisdictions, even if they're the primary beneficiary named in it. The courts will consider the circumstances, but litigation is expensive and slow.
Children from a prior relationship face the most risk in these scenarios. If no update is made and an estranged partner inherits, the children may receive nothing.
Timing: don't wait for the divorce order
The divorce order is not the finish line for estate planning. Update your documents at the point of separation, review them again when the property settlement is finalised, and check once more once the divorce order is granted. Three reviews, not one.
If you're also working through how to close joint accounts after separation, estate document updates can often be handled in the same period of financial reorganisation. Bundling these tasks together reduces the chance that any one of them falls off the list.
