When your binding death benefit nomination lapses: the 3-year rule and the renewal discipline

For super fund members who care about who receives their death benefit, the binding death benefit nomination (BDBN) is the principal mechanism for ensuring the trustee follows direction rather than exercising discretion. A valid BDBN binds the trustee to pay as directed; an invalid, lapsed, or absent BDBN gives the trustee discretion within the eligible beneficiary class. Many members understand the basics — name your beneficiaries, lodge the form, the trustee follows the direction. What many members don't realise is that for most public-offer funds (industry funds, retail funds, master trusts), the BDBN has a built-in expiry: the nomination lapses three years after it was first signed, last confirmed, or last amended (MoneySmart — super and death, https://moneysmart.gov.au/how-super-works/who-gets-your-super-if-you-die, accessed 6 May 2026). Once lapsed, the trustee reverts to discretion. The member who lodged a clear BDBN in 2022 may, by 2026, have an effectively unenforceable nomination.

The three-year rule for APRA-regulated super funds is set out in the Superannuation Industry (Supervision) Regulations 1994, regulation 6.17A (https://classic.austlii.edu.au/au/legis/cth/consol_reg/sir1994582/s6.17a.html, accessed 6 May 2026), which prescribes the form and operation of binding death benefit notices given to fund trustees. The regulation specifies the signing and witnessing requirements and provides that a notice ceases to have effect at the end of three years from the day it was first signed, last confirmed, or last amended (whichever is later). Most public-offer funds operate within this framework as their default; some funds also offer non-lapsing BDBNs as a separate product feature with stricter governance, and some have shorter periods — members should check what their specific fund provides. For SMSFs, the framework is materially different. The High Court confirmed in Hill v Zuda Pty Ltd [2022] HCA 21 (https://www.austlii.edu.au/cgi-bin/viewdoc/au/cases/cth/HCA/2022/21.html, accessed 6 May 2026) that SIS Reg 6.17A does not apply to self-managed super funds — SMSF BDBNs are governed by the trust deed, which can permit non-lapsing BDBNs that continue indefinitely until amended or revoked. SMSF members should confirm what their deed says, because the deed terms entirely determine the operation of any BDBN.

The lapse is rarely surfaced to members proactively. Some funds send reminder letters; many don't. Members who lodged a BDBN as part of initial fund onboarding — often years ago — may never have received a reminder, never thought about it, and continued under the assumption that the original nomination still applied. The lapse becomes apparent only at three points: at the member's death, when the trustee processes the death benefit and the family discovers the BDBN had lapsed (and by then no remedy is available); at a specific event prompting review such as divorce, marriage, birth of grandchildren, or the death of a beneficiary; or through adviser-led review, where the BDBN status is flagged as part of estate planning. For members without active adviser engagement on estate matters, the lapse can sit undetected for years.

When a BDBN has lapsed and the member dies, trustee discretion applies — the trustee determines distribution among eligible SIS Act dependants under ss.10 and 10A (spouse, children including adult children, financial dependants, interdependent persons), or to the legal personal representative (the estate). The trustee's process considers the family situation, any non-binding nominations on file, the member's documented wishes where any exist, and the fund's internal protocols. Where the lapsed BDBN had specified an outcome outside the trustee's typical decisions — excluding an estranged child, naming a charity through the LPR, allocating specific proportions in a blended-family situation — the trustee's discretion may not deliver the same outcome the member intended. Family disputes can arise, and the tax outcomes can also differ: ITAA 1997 s.302-195 (https://classic.austlii.edu.au/au/legis/cth/consol_act/itaa1997240/s302.195.html, accessed 6 May 2026) defines "death benefits dependant" for tax purposes — receiving the benefit tax-free — while non-tax-dependants (typically adult independent children) pay 15% plus the 2% Medicare levy on the taxable element of the taxable component (and 30% on any untaxed element), per the ATO's death benefits guidance (https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/super/withdrawing-and-using-your-super/superannuation-death-benefits, accessed 6 May 2026). The trustee's choice of beneficiary can therefore produce a materially different tax outcome from the one the lapsed BDBN would have delivered.

The renewal discipline for members in public-offer funds with three-year-lapsing BDBNs is straightforward but requires deliberate action. Diary the renewal date — mark roughly 2.5 years from the BDBN signing date as a review trigger, so the BDBN is refreshed before lapse rather than just after. Review the nomination at renewal: has the family situation changed, are the beneficiaries still appropriate, are the proportions still right? The renewal is a natural moment for a broader estate-planning check. Lodge a fresh BDBN — even if the content is unchanged, a fresh BDBN starts a new three-year period under reg 6.17A, and the form is typically simple and can be lodged online with most funds. Confirm with the fund — after lodging, confirm in writing that the fund has accepted the BDBN as binding; some lapses occur because a renewed BDBN was not properly accepted (incomplete signature, witness issues, non-compliance with fund-specific requirements). Keep a copy of the lodged BDBN and the fund's confirmation on file. For most members, the renewal is a 15-minute task once every 2.5 to 3 years.

Several events should prompt BDBN review regardless of where the member is in the three-year cycle. Marriage or de facto relationship change: a new partner is typically the intended beneficiary and an existing BDBN may not reflect this. Divorce or separation: a former spouse may be the named beneficiary in a stale BDBN, and the BDBN should be updated promptly. Birth of grandchildren where they are intended beneficiaries. Death of a named beneficiary, which makes the BDBN partially ineffective unless alternatives were specified. Change in fund — when rolling super to a different fund, a new BDBN must be lodged with the new fund because the old fund's BDBN doesn't transfer; this is a particularly common point of failure for members who consolidate super without proactive BDBN management. And any change in the member's intentions.

A specific point worth distinguishing is the interaction with reversionary pensions. A reversionary pension is a pension that automatically continues to a named beneficiary on the member's death — the reversion is set at pension commencement and typically does not lapse (subject to the fund's rules). A BDBN is a separate direction about death benefit treatment that can apply to accumulation balances, to non-reversionary pensions, or to direct the trustee's exercise of discretion. The two mechanisms aren't mutually exclusive: a member with both a reversionary pension and a BDBN has layered protection — the reversion handles the pension automatically, the BDBN handles other balances and ensures certainty for non-reversionary cases.

Who can you actually nominate? Eligible beneficiaries under the law

A binding death benefit nomination can only direct the benefit to someone the law permits a super fund to pay. Under regulation 6.22 of the Superannuation Industry (Supervision) Regulations 1994, a death benefit may be paid only to the member's legal personal representative (the estate) and/or to one or more of the member's dependants. Naming anyone outside those categories — a sibling, a parent, a friend, a charity — makes that part of the nomination invalid. To benefit them, you nominate your estate and deal with the gift in your will.

“Dependant” is defined in section 10(1) of the SIS Act 1993 and, read with the interdependency test in section 10A, covers four groups:

• A spouse — a legally married spouse, a de facto partner living with the member on a genuine domestic basis (including a same-sex partner), or a partner in a registered relationship.
• A child — of any age, defined broadly to include an adopted child, a stepchild, an ex-nuptial child, a child of the member's spouse, and a child within the meaning of the Family Law Act 1975 (for example, a child born through an artificial-conception or surrogacy arrangement).
• A person in an interdependency relationship (s.10A) — two people who have a close personal relationship, live together, and where one or each provides the other with financial support and with domestic support and personal care. This can capture, for instance, an adult child who lives with and cares for an ageing parent.
• A financial dependant — a person who was wholly or partly financially dependent on the member at the date of death.

A super death benefit is not part of your estate unless you direct it there — and who can receive it is fixed by the SIS Act. Your will cannot expand that list.

The tax definition is narrower — and different. Being an eligible SIS dependant lets a person receive the benefit; whether they receive it tax-free is a separate question, governed by ITAA 1997 s.302-195. An adult, financially independent child is a SIS dependant (can be paid) but usually not a tax dependant (taxed on the taxable component). A former spouse is the reverse — a tax dependant, but not a SIS dependant, so the fund cannot pay them directly, only through the estate. This asymmetry is one of the most common sources of surprise in super death benefits.

Example — the ineligible beneficiary. George, a 74-year-old widower with no children, wants his super to go to his younger sister. A BDBN naming his sister directly would be invalid, because a sibling is not a SIS dependant. The workable path is a BDBN to his legal personal representative, with his will leaving the proceeds to his sister. He should also plan for the tax: as a non-dependant she will pay 15% plus Medicare on the taxable element of the taxable component, and routing the benefit through the estate changes how the Medicare levy applies — worth modelling before he finalises the structure.

Non-lapsing nominations: how they work

A non-lapsing binding nomination does what the name suggests — it stays in force until the member amends or revokes it, with no three-year clock. It removes the renewal burden, but it does not remove the need to review.

Two routes exist. First, some public-offer funds offer a non-lapsing binding nomination as a product feature. Because regulation 6.17A prescribes only the lapsing form, a non-lapsing nomination sits outside 6.17A and relies instead on the fund's own trust deed and governing rules — which usually impose stricter acceptance and governance requirements. Not all funds offer it, so members must check their fund's rules. Second, and more commonly, SMSFs can permit non-lapsing BDBNs: because the High Court in Hill v Zuda confirmed that 6.17A does not apply to SMSFs, an SMSF nomination is governed entirely by the trust deed, and a well-drafted deed can authorise a nomination that continues indefinitely.

The catch with SMSFs is strict compliance with the deed. Courts have repeatedly invalidated SMSF BDBNs that failed to follow the deed's own requirements — in Munro v Munro [2015] QSC 61 a nomination was ineffective because it did not comply with the deed's terms, and in Wooster v Morris [2013] VSC 594 a nomination was struck down for non-compliance. A non-lapsing SMSF BDBN is only as good as its alignment with a current, correctly drafted deed.

Non-lapsing does not mean set-and-forget. A nomination that never expires will still, twenty years later, pay exactly who it names — including a person you long ago stopped intending to benefit.

Example — the stale non-lapsing nomination. Marie, 63, made a non-lapsing BDBN through her retail fund in 2015 naming her then-husband. They divorced in 2021. Because the nomination is non-lapsing it did not expire — it remains binding on the trustee, and on the current facts her super would still be paid to her ex-husband. A lapsing BDBN would at least have failed safe, reverting to trustee discretion after three years; the non-lapsing form kept a stale direction alive. The fix is simple but must be deliberate — lodge a fresh nomination. Non-lapsing nominations trade the renewal chore for a review discipline: every life event (marriage, divorce, a death, a new fund) has to trigger a check, precisely because nothing else will.

What do worked strategy examples show?

These two cases show how the lapse risk lands differently for different members. Illustrative only — not personal advice — using FY25-26 figures.

Case 1 — Helen, 71, widow with a public-offer industry super fund. Helen lodged a BDBN in March 2022 nominating her late husband as primary beneficiary and her two adult children equally as secondary beneficiaries. Her husband died in 2024. She has not refreshed the BDBN. By March 2025 the original BDBN had passed its three-year period and lapsed under SIS Reg 6.17A. Her current super balance is $380,000 in account-based pension. On these facts, the rational pathway is to lodge a fresh BDBN immediately — naming the two adult children as primary beneficiaries in whatever proportion she intends, with proper witnessing under reg 6.17A's two-witness rule (witnesses must be over 18 and not named beneficiaries). The trap to avoid is assuming the original BDBN "still works because the secondary beneficiaries were already named" — once the three-year window passes, the entire notice ceases to have effect and the trustee falls back to discretion within the SIS dependant class. Her adult children, as non-tax-dependants under ITAA 1997 s.302-195, will pay 15% plus Medicare on the taxable element of the taxable component regardless — but a fresh BDBN ensures the trustee's hands are bound to her stated proportions rather than reaching its own conclusion about how to split between two adult siblings.

Case 2 — Robert and Susan, both 68, blended-family SMSF trustees. Robert and Susan run an SMSF with Robert having two adult children from a previous marriage and Susan having one. The trust deed permits non-lapsing BDBNs, and Robert lodged one in 2018 specifying a 100% reversion to Susan if she survives him, otherwise 50% to his two children equally and the remaining 50% to Susan's daughter. On these facts, the SMSF deed governs entirely (not SIS Reg 6.17A — confirmed by the High Court in Hill v Zuda [2022] HCA 21), and the 2018 BDBN remains in force unless Robert amends or revokes it. The rational pathway is to confirm with the SMSF lawyer that the deed clauses authorising non-lapsing BDBNs are still current (deed amendments since 2018 should be reviewed) and that the 2018 BDBN was executed in accordance with the deed's specific requirements at that time. The trap to avoid is two-fold: first, assuming a 2018 BDBN still works without checking the deed has been kept aligned with the 2022 Hill v Zuda decision and any later trustee changes; second, assuming the SMSF rules carry over to any retail or industry-fund balances either spouse holds — those public-offer balances are subject to the three-year lapse rule under reg 6.17A and need their own renewal cycle. A fresh review of all BDBNs across all funds at one sitting, with the SMSF deed in hand alongside the public-offer fund forms, is the right discipline.

The BDBN is the principal estate-planning tool within the super system, but its effectiveness depends on currency. A BDBN lodged years ago and not refreshed may be unenforceable when it matters most — at the member's death. The cost of preventing this is small: a 2.5-year review cycle for public-offer funds, an SMSF deed check for SMSF members, a quick form lodgment, and written confirmation from the fund. The cost of not preventing it can be substantial — divergence from the member's intentions, family disputes, and different tax outcomes than the member's BDBN would have delivered. For super fund members who took the time to lodge a BDBN in the first place, the renewal discipline is the way to ensure the BDBN actually does what they intended when the moment comes.
