Your will doesn't control your super: what happens to it when you have no valid death benefit nomination

Here's something that surprises a lot of people who think their affairs are in order: your superannuation does not automatically follow your will. Super is held by your fund's trustee, not by you personally, so it isn't part of your estate unless it's specifically directed there. That means if you die without a valid binding death benefit nomination — because you never made one, made a "preferred" one that isn't binding, or let an old one quietly expire — the decision about who receives your super, often one of your largest assets, falls to the fund trustee, who exercises discretion within the limits of superannuation law. That discretion can mean long delays, family disputes, an unexpected tax bill, and money going somewhere you'd never have chosen. This article explains what happens when there's no valid nomination, who the trustee can pay, how it decides, and how to take back control. It is general information only, not personal advice.

What is the misunderstanding at the heart of it?

Many people carefully draft a will believing it governs everything they own, then assume their super is covered too. It usually isn't. Your super death benefit can be directed in one of three ways: a valid binding nomination (the trustee must pay as you direct), a reversionary pension (an income stream that automatically continues to a nominated person, usually a spouse), or — if neither is validly in place — trustee discretion. Only if your super is paid to your estate does your will actually control it. Absent a direction, the will and the super run on separate tracks.

Is "no valid nomination" more common than people realise?

Your super falls to trustee discretion if you never made a nomination; if you made a non-binding ("preferred") nomination, which only guides the trustee and can be overridden; if you made a lapsing binding nomination that expired — a lapsing nomination must be renewed every three years or it lapses, and many are never renewed, though non-lapsing binding nominations that don't expire are also available (MoneySmart); if your nomination was invalid (wrong witnessing, ambiguous wording, or it named someone who isn't legally eligible); or if your nominated beneficiary had died or was no longer eligible by the time you did. Any one of these hands the decision to the trustee — and the clients most exposed are often the diligent ones who did nominate, years ago, and never checked it again.

Are there limits on who the trustee can pay?

The discretion isn't unlimited — by law a death benefit can only go to one of your superannuation-law dependants or to your legal personal representative (your estate). Your dependants for this purpose are your spouse (including de facto and same-sex partners — and an estranged-but-not-divorced spouse can still qualify); your children; anyone who was financially dependent on you at the date of death; and anyone in an interdependency relationship with you (a close personal relationship where you live together and one or both provides financial, domestic and personal support) (ATO). There's an important wrinkle with children: a child of any age can receive a death benefit as a lump sum, but a death benefit pension (income stream) can only be paid to a child who is under 18, or under 25 and financially dependent, or who has a disability. The other option is the estate — if the trustee pays your legal personal representative, the super then flows through your will (or, if you have no will, the intestacy rules). "Next of kin" as a general idea has no automatic claim; only these specific categories do.

How does the trustee decide — and why is it slow and contestable?

With no binding direction, the trustee has to do real work: identify the potential beneficiaries, invite claims, gather evidence of relationships and dependency, and then exercise its discretion on who gets what and in what shares. Bigger funds run a formal "claim-staking" process, sometimes letting interested parties object before the decision is locked in. All of this takes time — commonly many months, and well over a year in contested cases — at exactly the moment your family may need the money. Unhappy claimants can object and ultimately complain to the Australian Financial Complaints Authority (AFCA), which can review the decision. Disputes between a current spouse and adult children from an earlier relationship are common, and they can get bitter. And the result is decided on relationships and dependency at the date of death, not on your intentions: the trustee might split the benefit in ways you'd never have chosen, pay a spouse you were long estranged from, or pay beneficiaries directly when you'd intended the money to flow through your estate into a testamentary trust.

Does who receives it also drive the tax?

Super death benefits are taxed according to who gets them. Paid to a tax dependant — broadly a spouse, a child under 18, a financial dependant, or an interdependency partner — the benefit is generally tax-free. Paid to a non-tax-dependant — typically an independent adult child — the taxable component is taxed at 15% plus the 2% Medicare levy on the taxed element, an effective 17%, and at 30% plus Medicare (32%) on any untaxed element (ATO). This is exactly why the superannuation-law definition of dependant (who can receive) and the narrower tax definition of dependant (who receives it tax-free) matter: an independent adult child is a dependant who can receive the benefit, but not a tax dependant, so they're taxed. Because the trustee chooses the recipient, its decision can directly change the tax bill — and a member who wanted to manage that, by directing to a tax dependant or using a recontribution strategy to lift the tax-free portion, loses that control if it falls to discretion. Routing through the estate doesn't automatically make it tax-free either; the tax still looks through to who ultimately benefits.

Is the SMSF version of this problem the dangerous one?

In a self-managed fund, the "trustee" exercising the discretion is the surviving family — the remaining trustees or directors, often the surviving spouse or the deceased's children. They may have a stark conflict of interest, because they could decide to pay the benefit to themselves. There's a well-known line of cases (the Katz v Grossman authority is the usual reference point) where a surviving controller lawfully directed a death benefit away from the people the deceased clearly intended, and the courts upheld it — precisely because, without a binding nomination, the discretion genuinely belonged to whoever controlled the fund. The lesson is that in an SMSF, whoever controls the fund after you die effectively controls your super when there's no binding nomination. Getting your binding nomination and your trustee succession (the trust deed, the corporate trustee, who gets appointed) right together is essential; one without the other leaves a gap.

What do worked examples look like?

These show the discretion playing out in the two settings where it does the most damage. They are illustrative only, not personal advice, and outcomes depend on your fund's rules and your circumstances.

Noela, 73, is in a large industry super fund. She remarried a few years ago and has two adult children from her first marriage. She made a binding nomination to her late first husband long ago and never updated it, so her current nomination on file is now lapsed, and she assumes her will — which leaves everything split between her two children — covers her super. On these facts Noela has a problem she doesn't know about. Her super is not controlled by her will, and her old nomination is invalid and lapsed, so on her death the benefit falls to trustee discretion. The trustee must weigh the competing claims of her current husband (a spouse, and very likely a dependant) and her two adult children (eligible to claim as children, able to take a lump sum). There's a real chance the trustee pays a large share, or all, to her husband rather than the 50/50-to-the-kids split her will intended, because her will never controlled the super in the first place; the process could take many months, and if the children object it could end up at AFCA. On these facts it is generally rational to put a current, valid binding nomination in place reflecting what she actually wants — whether to her husband, to her children, or to her estate so the will (and any testamentary trust) governs it. If she wants the children protected, directing the super to her estate and structuring it through her will is the deliberate path. Either way, the lapsed nomination is the gap to close now.

Raymond, 78, runs an SMSF with his second wife as the only other member and trustee. His adult son from his first marriage is the intended beneficiary of his super, but Raymond never made a binding nomination — "it's our own fund, it'll be fine." On these facts Raymond is walking into the classic SMSF trap. If he dies with no binding nomination, the discretion over his death benefit sits with the surviving trustee, his second wife, who has a direct conflict of interest and could lawfully decide to pay the benefit to herself rather than to his son — courts have upheld exactly this kind of outcome, because without a binding direction the discretion really is the survivor's to exercise. "It's our own fund" is the reason it's more dangerous, not less. On these facts it is generally rational for Raymond to do two things together: make a valid binding nomination directing his benefit to his son (or to his estate, if he wants his will to control it), and review who controls the fund after his death — the trust deed and trustee or director succession — so control of the fund can't be used to override his wishes. Done properly, his son's entitlement is locked in; left as is, it's at the discretion of the person least likely to honour it.

The thread through both cases is the same: leaving your super to trustee discretion is leaving one of your biggest assets to be handed out by someone else, on rules that may not match your wishes, after months of delay, possibly with tax and disputes attached. The fix is almost always simple — check what's actually on file (nomination type, validity, expiry, and any reversionary pension), decide deliberately who should receive your super and whether it should go to them directly or via your estate, make a valid binding nomination (and consider a non-lapsing one so it doesn't silently expire), use a reversionary pension where you simply want income to continue to your spouse, and, if you have an SMSF, fix trustee succession at the same time. Coordinate it with the tax position and revisit it after any major life event: marriage, divorce, a new partner, a child becoming independent, or the death of someone you'd nominated. Because lapse periods, tax rates and the rules vary by fund and change over time, confirm the current details with your fund and get personal financial and legal advice before acting. Your will is worth having — but it won't reach your super unless you make sure it can.
