Binding vs non-binding death benefit nomination: which should you have?
A binding nomination tells your super fund exactly who to pay. A non-binding one is just a preference. Here's the difference, the 3-year trap, and how to check yours.
When you join a super fund, somewhere in the paperwork you're asked to name a beneficiary — the person who should receive your super if you die. Most people tick a box and never think about it again. But there's a world of difference between the two kinds of nomination you can make, and it decides whether your wishes are followed or merely considered. Here's the plain-English version.
The short answer
A binding death benefit nomination legally directs your fund to pay your super to the people you've named (as long as the nomination is valid and they're eligible). A non-binding nomination is only a preference — the trustee takes it into account but makes the final call itself (ATO). If certainty matters to you, a valid binding nomination is the stronger choice.
Non-binding: a preference, not an instruction
With a non-binding nomination, you're telling the fund who you'd like to receive your super. But if you die, the trustee of the fund can use its own discretion to decide which of your dependants receives the benefit, or pay it to your estate to be distributed under your will (ATO).
Trustees usually try to honour your wishes, but "usually" isn't "always" — and the process of the trustee assessing competing claims can take months, which is hard on a grieving family.
Binding: an instruction the fund must follow
A valid binding nomination removes that uncertainty. The fund must pay your super to the beneficiaries you named, in the proportions you set, provided each is an eligible beneficiary — a dependant under super law, or your legal personal representative (Moneysmart).
There's an important sub-distinction:
- Lapsing binding nominations expire — commonly every three years — and once they lapse they're treated like a non-binding nomination again.
- Non-lapsing binding nominations don't expire, but not every fund offers them.
Each fund sets its own rules, and they're spelled out on the form you sign (Moneysmart).
The 3-year trap
This is the part that catches people out. You make a careful binding nomination, feel good about it, and forget it. Three years later it quietly lapses — and now the trustee is back to deciding. If your life has changed in the meantime (marriage, separation, a new child), the gap between what you intended and what happens can be wide.
The fix is simple: find out whether your nomination is lapsing or non-lapsing, note the expiry date if it lapses, and set a reminder to renew it.
Who you're actually allowed to name
A binding nomination can only go to an eligible beneficiary: a dependant under super law (your spouse or de facto partner, your child of any age, or someone in an interdependency relationship with you) or your legal personal representative — the executor of your estate (ATO).
If the person you want to provide for isn't a dependant under super law — for example, a parent or sibling overseas — the usual route is to make a binding nomination to your legal personal representative, so the money flows into your estate and is distributed according to your will. (We cover this in more detail in will my Australian super reach my family overseas?)
How to check and update yours
- Log in to your super fund (or call them) and find your current beneficiary nomination.
- Check the type — binding or non-binding, lapsing or non-lapsing.
- Check it's still valid and reflects your life today.
- Update it using the fund's nomination form if anything's off, and note any expiry date.
- Write down where this lives — your fund, member number and login — somewhere your family can reach. That's exactly what a secure vault is for.
Frequently asked questions
Is a binding nomination better than a non-binding one? If you want certainty about who receives your super, yes — a valid binding nomination must be followed, while a non-binding one only guides the trustee's discretion (ATO).
Does a binding nomination expire? Often. Many binding nominations are "lapsing" and expire every three years; some funds offer "non-lapsing" ones that don't. Check your fund's rules (Moneysmart).
What happens if my binding nomination lapses? It's generally treated like a non-binding nomination, meaning the trustee decides where your super goes (Moneysmart).
Can I make a binding nomination to my estate? Yes — you can nominate your legal personal representative, which directs your super into your estate to be distributed under your will (ATO).
