Update Superannuation Beneficiary After Divorce in Australia
Your Ex Could Still Get Your Super If You Die
A divorce order does not automatically change who receives your superannuation death benefit. Unlike a will — where a finalised divorce revokes gifts to an ex-spouse under state succession legislation — your super fund operates outside your estate entirely. The fund trustee decides who gets the payout based on whatever beneficiary nomination sits on file, and if that nomination still names your former partner, the trustee can legally pay them.
This catches people off guard because they assume the divorce took care of everything. It didn't. Your super, your life insurance through super, and any standalone life insurance policies all require separate, deliberate updates.
Binding vs Non-Binding Death Benefit Nominations
Super funds offer two types of beneficiary nominations, and the distinction matters enormously after divorce.
A non-binding nomination is a suggestion to the trustee. You name preferred beneficiaries, but the trustee retains discretion to distribute the death benefit among your dependants and legal personal representative as they see fit. If your ex-spouse qualifies as a dependant (which is possible if they were receiving spousal maintenance), the trustee could still direct funds to them despite your nomination saying otherwise.
A Binding Death Benefit Nomination (BDBN) removes that discretion. When a valid BDBN is on file, the trustee must pay your death benefit to the people you've nominated, in the proportions you've specified, with no room for interpretation. This is the only way to guarantee your ex-spouse receives nothing from your super if you die.
Most BDBNs are lapsing — they expire every three years and must be renewed. Some funds offer non-lapsing BDBNs that remain valid until you change them, but not all do. Check your fund's product disclosure statement.
How to Lodge a BDBN After Divorce
The process is straightforward but rigid in its requirements:
Download your fund's BDBN form. Every major fund (AustralianSuper, Aware Super, QSuper/Australian Retirement Trust, REST, Hostplus) has its own version. Generic forms are not accepted.
Nominate your beneficiaries. You can only nominate dependants as defined by superannuation law — your current spouse or de facto partner, your children (including adult children and stepchildren), anyone in an interdependency relationship with you, or your legal personal representative (your estate). Allocate percentages that total exactly 100%.
Have the form witnessed. Two independent witnesses aged 18 or over must watch you sign the BDBN and then sign it themselves. Neither witness can be a nominated beneficiary. This witnessing requirement is not optional — an unwitnessed or incorrectly witnessed BDBN is invalid and the trustee falls back to discretion.
Submit directly to your fund. Post or upload the completed form through your fund's member portal. Keep a copy and note the date — you'll need to renew it before the three-year expiry.

Life Insurance Beneficiary Through Super
Most Australians hold their life insurance (death cover and total & permanent disability) inside their super fund rather than as a standalone policy. The beneficiary for this insurance payout follows the same nomination structure as your super balance — your BDBN covers both.
If you hold standalone life insurance outside super, contact the insurer directly to update the policy owner and beneficiary details. This is a separate process governed by your insurance contract, not superannuation law.
What Happens If You Do Nothing
If you die without a valid BDBN and your most recent non-binding nomination still names your ex-spouse, the trustee will consider all potential claimants. Your ex-spouse, your children, and any new partner would all be in the mix. The trustee's decision can take time, during which your family may not receive the benefit.
The simplest way to avoid this is to lodge a fresh BDBN within days of your divorce being finalised. The Queensland After-Divorce Checklist includes the exact sequence for updating your super beneficiary alongside every other post-divorce administrative task — from name changes through to property transfers and ATO notifications.
