Reversionary pension nominations versus binding death benefit nominations: which prevails when both exist on the same super interest

For Australian super members — particularly those running self-managed super funds and managing substantial death benefit estate planning — two distinct nomination mechanisms operate to direct super on death, and the interaction between them is one of the most common sources of estate planning confusion and post-death disputes. The reversionary pension nomination is made when a pension is commenced, identifying a person to whom the pension automatically continues on the original member's death; the binding death benefit nomination (BDBN) under regulation 6.17A of the Superannuation Industry (Supervision) Regulations 1994 is a separate document instructing the trustee on how to distribute the death benefit. When both exist on the same super interest — common for members who have commenced a pension and subsequently completed a BDBN as part of broader estate planning — which document prevails is a question determined by the fund's trust deed in the first instance, with default rules typically favouring the reversionary nomination for the pension portion and the BDBN for any residual. For SMSF members and their advisers, getting the coordination right requires understanding both mechanisms, the deed framework that governs priority, and the practical drafting approaches that prevent conflicts.

The reversionary pension nomination is built into the pension documentation at commencement. When a member commences an account-based pension, transition-to-retirement income stream, or other income stream from super, the pension establishment paperwork typically includes a section for "reversionary beneficiary" — a single person who will automatically continue to receive the pension on the original member's death. The eligible beneficiaries for reversionary nomination are narrower than the BDBN-eligible pool, generally being SIS dependants only under section 10 of the SIS Act 1993 — spouse (married, de facto, or registered same-sex partner), child under 25 who is financially dependent, dependent child with a qualifying disability of any age, or other interdependant or financial dependant. The legal personal representative (estate) cannot be a reversionary beneficiary — a pension is paid to a natural person, not to an estate. Once the pension commences with a reversionary nomination, the nomination is generally fixed for the life of the pension — the member cannot change it without commuting the pension and recommencing with new terms, which has TBC implications. On the original member's death, the pension simply continues at the same rate (subject to fund rules around minimum drawdown and any optional adjustments), with the reversionary beneficiary becoming the new pensioner. There is no trustee discretion, no probate dependency, and no delay in continuing the income.

The BDBN is a separate document operating at the trustee level. The member completes a BDBN form identifying who should receive the death benefit — eligible beneficiaries are SIS dependants and the legal personal representative (estate), with the LPR being the additional category compared with reversionary nominations. The BDBN can specify percentages to multiple beneficiaries, cover all of the member's super interests in the fund, and address contingencies (for example "100% to spouse if living, otherwise 50% to each child"). The BDBN is binding on the trustee — subject to the form being valid (correct execution, witnessing, signed by the member, eligible beneficiaries, within any required time period) — meaning the trustee must distribute according to the nomination without applying further discretion. APRA-regulated retail and industry super funds typically require BDBNs to be renewed every three years under SIS Reg 6.17A. Self-managed super funds can use non-lapsing BDBNs subject to the trust deed permitting them — the High Court confirmed in Hill v Zuda Pty Ltd [2022] HCA 21 that the three-year lapsing rule in SIS Reg 6.17A does not apply to SMSFs, so non-lapsing BDBNs are valid for SMSFs where the trust deed allows.

The conflict scenario arises when a member has both a reversionary nomination on their pension and a BDBN covering their super interests, and the two documents direct to different beneficiaries. Common patterns include: pension commenced years ago with reversionary spouse, BDBN signed later naming children for the entire super; different advisers handled different documents (fund's pension nomination versus estate planning lawyer's BDBN), with neither knowing the other; member's circumstances changed (separation, remarriage, new beneficiary intent) and one document was updated without the other; or the member simply didn't realise the two nominations could conflict. When the member dies, the executor or trustee discovers the two conflicting documents and must determine priority — and the answer depends on the fund's trust deed.

The trust deed framework is the principal authority on priority. For SMSFs, the trust deed (executed when the fund was established and varied periodically since) sets out the rules for death benefit distribution. Older deeds — drafted before the BDBN framework was well-developed or before the rise of reversionary pensions — may not address the priority question explicitly, leaving the trustee to resolve the conflict using general fiduciary principles or default rules. Modern professionally-drafted deeds typically address the priority question directly, with three common approaches: Reversionary priority for pension portion — the reversionary nomination governs the pension; the BDBN governs any residual (accumulation phase, lump sums); BDBN priority overall — the BDBN governs everything, including pensions, with the reversionary nomination treated as a default that the BDBN can displace; Member-elected priority — the BDBN form includes an explicit clause stating whether it overrides any prior reversionary nomination, and the trustee follows the member's election. For APRA-regulated funds, the trust deed approach is typically standard across the fund — members don't have individual control over the priority rules. For SMSFs, members can choose deeds with specific approaches, providing more planning flexibility.

The default rule where the deed is silent typically favours the reversionary nomination for the pension portion. The reasoning is that the reversionary nomination was made at the time of pension commencement and was an integral part of the pension structure; a subsequent BDBN should not be assumed to displace it without clear intent. The BDBN governs the residual — non-pension super such as accumulation balance — but doesn't override the established pension reversionary nomination. This default produces predictable outcomes for many members where the reversionary spouse is the intended beneficiary anyway. For members whose intent has changed and the BDBN reflects the new intent, the default rule produces an unintended outcome — the pension still goes to the reversionary spouse despite the BDBN naming someone else.

The strategic considerations for members deciding how to use both mechanisms have a specific shape. Reversionary advantages: automatic continuation on death, no trustee discretion, no probate dependency, no application or process delay, simple administration, the spouse beneficiary continues receiving income immediately. Importantly, the TBC credit for the reversionary recipient is deferred for 12 months under section 294-25 of the ITAA 1997, giving the surviving spouse a year to restructure their own super position before the pension counts against their personal TBC. BDBN advantages: flexibility, ability to specify percentages to multiple beneficiaries, ability to include the estate (LPR) as a beneficiary (useful for tax planning around testamentary trusts), updateable as circumstances change, can address contingencies. Both together is the most common and often optimal approach — reversionary spouse on pension for continuity and the 12-month TBC deferral, BDBN naming spouse (or estate) for non-pension residual and contingent beneficiaries. The two documents should be drafted to coordinate, not conflict. The related article on articles/2026-05-05-bdbn-lapse-3-year-rule covers the BDBN lapse rules in more detail.

The practical drafting approach for coordinated nominations: Coordinate the documents. Ensure both reflect the same primary intent — reversionary names spouse for pension; BDBN names spouse for residual. Address the residual explicitly. What happens to non-pension super on death? BDBN should specifically address. Plan for contingencies. What if the reversionary spouse predeceases the member? The reversionary nomination becomes ineffective on the spouse's death; the pension continues as a regular account-based pension to the original member; on the member's later death (now without a reversionary), the BDBN or default rules govern. Multiple-pension scenarios. If the member has multiple pensions (within one fund or across funds), each reversionary nomination should be reviewed and confirmed consistent. Update on life events. Marriage, divorce, birth of children, death of beneficiaries, significant relationship changes — all should trigger a nomination review. Document the trail. Keep records of all nominations, deed provisions, and any priority elections; the executor will need this on death.

The executor experience when discovering dual nominations on death has a specific shape. The executor or trustee identifies all nominations on file — reversionary on each pension, BDBN(s), informal directions or correspondence. Each nomination is assessed for validity (correct execution, beneficiaries eligible, within any required time period, deed compliance). Where conflicts exist, the trust deed analysis determines priority. The trustee makes the death benefit distribution following the resolved priority, paying pension to reversionary beneficiary (where applicable), residual under BDBN (where applicable), and any unresolved portion under default rules with trustee discretion. For complex cases, advice from estate planning counsel is often sought before final distribution. The process can take months for complicated estates, with the surviving spouse and other beneficiaries waiting for resolution.

The practical advice work for practitioners advising on super estate planning has a specific shape. Identify all existing nominations — reversionary on each pension, BDBN, any informal directions. Confirm trust deed treatment of priority and lapse rules — this is the foundational analysis. Map intended outcome — who should get what, when, in what form. Coordinate documents — ensure reversionary and BDBN reflect the same intent or are deliberately different. Address contingencies — predeceased beneficiaries, divorce, remarriage. Document the approach for future advisers and executors. Review periodically — major life events, deed changes, contribution caps. Update deed if needed — many older SMSF deeds need updating to address modern nomination practices.

What do worked planning examples show?

These two cases show how the reversionary-versus-BDBN priority issue plays out for typical SMSF estate planning scenarios. Illustrative only — not personal advice — using FY25-26 figures.

Case 1 — Robert, 70, SMSF member with $1.8m account-based pension (reversionary spouse Helen) and $200k accumulation balance. Robert signs a non-lapsing BDBN naming Helen for 100% of his super interests. On these facts, no conflict exists — both documents direct to Helen. Trust deed (modern, addresses priority): BDBN governs unless a valid reversionary nomination applies, so reversionary continues for the pension portion (auto-continuation); BDBN governs the $200k accumulation residual. On Robert's death, Helen receives the pension as continuation (no application required) and the $200k accumulation balance under the BDBN. The TBC credit for the pension is deferred for 12 months under s.294-25, giving Helen the year to restructure her own super. Outcome: smooth, clean, predictable. The trap to avoid is failing to coordinate — if the BDBN had named children instead of Helen, the trust deed analysis would have determined whether children get the residual while Helen continues the pension.

Case 2 — Margaret, 75, SMSF member with $1.2m account-based pension (reversionary spouse George, but George died in 2023 without Margaret updating). Margaret signs a BDBN in 2024 naming her two adult children for 100% of super interests. On these facts, the reversionary nomination became ineffective on George's death in 2023. From that point, the pension continued as Margaret's account-based pension with no live reversionary. The 2024 BDBN governs the death benefit distribution on Margaret's eventual death. On Margaret's later death, the BDBN directs the trustee to distribute the entire balance (pension commuted to lump sum at her death) to the two adult children equally. Outcome: BDBN governs cleanly because the reversionary was no longer effective. The trap to avoid is assuming the reversionary still operates after the reversionary's death — many members don't realise the nomination becomes ineffective and don't review documents accordingly. If George had survived and the BDBN had named children, the conflict would have been live and the trust deed analysis would have governed.

For Australian SMSF members and other super members managing death benefit estate planning, the interaction between reversionary pension nominations and binding death benefit nominations is one of the central planning considerations. Where both exist on the same super interest, the trust deed determines priority, with default rules typically favouring the reversionary for the pension portion and the BDBN for any residual. The optimal approach for most members is coordinated nominations — reversionary spouse on pension for automatic continuity and the 12-month TBC deferral under s.294-25, BDBN governing the non-pension residual and contingent beneficiaries — drafted with explicit coordination to avoid conflict. The advice work is to identify all existing nominations, confirm the deed treatment, map intended outcomes, coordinate the documents, and review periodically. The cost of getting it wrong can be substantial — disputes, delayed distributions, unintended beneficiary outcomes, family conflict — all avoidable with careful drafting and ongoing review.
