Divorce changes almost everything about your life — where you live, how your finances work, who you call in an emergency. But one document people forget to touch is the one that decides what happens to everything they own if they die: their will. And the truth is more complicated than most people expect. Divorce does change your will automatically in some ways, but not in all the ways you'd assume, and the gap between what you think has changed and what has actually changed is where families get caught out.
What Divorce Automatically Changes
In every Australian state and territory, finalising a divorce has a specific legal effect on an existing will: any gift left to your former spouse is automatically revoked, and if they were named as your executor, that appointment is cancelled too. The rest of the will generally stays valid and continues to operate as written.
That sounds reassuring, but it creates its own problems. If your will named your ex-spouse as the sole beneficiary and sole executor, revoking those clauses can leave you with a will that has no effective instructions at all — which usually means your estate is distributed under the intestacy rules of your state, as if you had no will. Intestacy rules follow a fixed legal formula and won't reflect your actual wishes, your children's ages, or your current relationships. Rewriting your will after divorce isn't optional housekeeping — it's the only way to make sure a gap in coverage doesn't hand that decision to a formula instead of to you.
What Divorce Does Not Change
This is the part that trips people up most often. Separation is not divorce. Many couples live separately, sometimes for years, without ever formalising a divorce. During that entire period, your old will remains fully valid — including any gifts to your separated (but not yet divorced) spouse. If you die while separated but not divorced, your ex could still inherit exactly as your will says, regardless of how estranged you've become.
Divorce also has no automatic effect on documents outside the will itself. Your enduring power of attorney, for example, doesn't update itself — if you appointed your former spouse to manage your finances or make medical decisions on your behalf, that appointment can remain in force after divorce unless you formally revoke it and appoint someone new. The same applies to superannuation death benefit nominations and life insurance beneficiaries, which sit completely outside your will and follow their own rules.
Superannuation and Binding Nominations
Superannuation is usually one of the largest assets a person owns, and it doesn't automatically form part of your estate — it's governed by whatever nomination you have on file with your fund. A binding death benefit nomination naming your former spouse will generally lapse once your divorce is finalised, which is helpful, but it also means your death benefit reverts to a default arrangement decided by your fund's trustee unless you put a new nomination in place. Don't assume the lapse alone protects your intentions — an out-of-date or absent nomination just moves the decision to someone else. Review and resubmit your nomination as soon as your divorce is finalised, and check whether it needs to be renewed periodically, since many binding nominations expire every three years regardless of your relationship status.
Property Settlements and Your Estate
A formal property settlement — whether reached through consent orders or a binding financial agreement — changes what you actually own, and therefore what your will has to deal with. Assets that were once jointly held may now be solely yours, or vice versa. If your will makes specific gifts of property you no longer hold, or fails to mention new property you've acquired through the settlement, those clauses can fail or create confusion for your executor. This is also the point at which many people should reconsider how assets like the family home are held — whether as joint tenants or tenants in common — since that structure determines whether the asset passes automatically to a co-owner or through your estate.
A Practical Checklist After Divorce
Once your divorce is finalised, work through these items in order:
- Write a new will rather than relying on the automatically revoked version of the old one.
- Revoke and reissue your enduring power of attorney, naming someone you currently trust.
- Review any healthcare or medical treatment directive that named your former spouse.
- Update superannuation death benefit nominations with every fund you hold.
- Update beneficiaries on any life insurance policies.
- Reconsider guardianship arrangements for children under 18 if circumstances have changed.
- Check how jointly held property is titled and whether that still matches your intentions.
If children are involved, this is also a good time to think about a testamentary trust structure, which can protect an inheritance from being exposed to a future relationship breakdown or creditor claim involving your children. A proper estate planning review after a major life event like divorce is worth doing properly rather than patching one document at a time.
Keeping Everything Together and Up to Date
The hardest part of updating your affairs after divorce usually isn't any single document — it's making sure every document that matters is actually current, and that your family or executor can find the right version when it counts. Old wills, outdated powers of attorney, and lapsed nominations have a way of surviving in filing cabinets and old email attachments long after they should have been replaced.
Custodium Vault gives you one secure place to store your current will, power of attorney, superannuation and insurance nomination records, and a letter of wishes for your executor — with the old versions cleared out so there's no confusion about which document is current.
