Contesting an Unfair Superannuation Death Benefit Decision in Australia

§1Contesting an Unfair Superannuation Death Benefit Decision in Australia

§2A Concrete Situation: When the Trustee's Decision Feels Wrong

When Marco died unexpectedly at 54, he left behind a de facto partner of seven years, two adult children from a previous marriage, and a superannuation balance of $420,000. He had made no binding death benefit nomination. The trustee of his industry fund decided to split the death benefit between his adult children, reasoning that they were financially dependent on him — but his de facto partner, who had lived with him and shared all household expenses, received nothing. She believes the trustee failed to properly weigh her financial and personal relationship with Marco when making the decision, and she wants to know whether she can challenge the outcome.

This situation is more common than most Australians realise. Super trustees make death benefit decisions every day, and those decisions are not always transparent or well reasoned. Here is what you need to know about contesting one.

§3Why Superannuation Death Benefits Are Different From an Estate

The single most important thing to understand is that superannuation does not automatically form part of a deceased person's estate. It is held in trust by the super fund, and the trustee — not the deceased's will — decides where the money goes (unless a valid binding death benefit nomination exists). This means that even if the deceased wrote "my partner gets my super" in their will, that instruction carries no legal force over the trustee's decision.

This was squarely at issue in Reynolds v Bonnici [2017] NSWSC 828, where the court examined a scenario in which the deceased had declared in his will that his partner was "the beneficiary of my super." The court's analysis made clear that a superannuation benefit is governed by the fund's rules and the trustee's discretion, not by testamentary wishes alone. A will simply cannot override the governing rules of a super fund.

The implications are significant. Family members who expect the will to protect them may be blindsided by a trustee's decision that directs the entire benefit elsewhere. Conversely, individuals who are not mentioned in the will at all — like a long-term de facto partner — may have a strong claim through the super fund if they qualify as a dependant.

§4Who Can Make a Claim and How Eligibility Is Decided

Under Australian superannuation law (which is primarily governed by federal legislation), trustees may pay a death benefit to one or more of the following:

Whether a de facto relationship actually existed at the date of death can be a contested question. In Sun v Chapman [2022] NSWCA 132, the New South Wales Court of Appeal recognised that the question of whether someone qualifies as a de facto partner — and therefore an eligible person — may involve competing evidence and require careful factual analysis. This matters: a surviving partner whose status is disputed will need to present solid evidence of the relationship.

The trustee weighs all eligible dependants' circumstances, including the nature of each relationship with the deceased, the degree of financial dependency, and the terms of any trust deed or fund rules. In Watson Wyatt Superannuation Pty Ltd v Oberlechner & 2 ors [2008] NSWSC 272, the court examined precisely how trust deed clauses interact with a trustee's obligations when deciding how to allocate a death benefit among competing claimants.

§5Grounds for Challenging the Trustee's Decision

You do not simply have to accept a trustee's decision because the trustee has discretion. That discretion must be exercised properly. A challenge may succeed where the trustee:

• Failed to follow the trust deed or fund rules — for example, by not considering all eligible dependants;
• Ignored relevant factors — such as a surviving partner's financial dependency or the nature of a long-term relationship;
• Relied on irrelevant factors — for example, the deceased's estrangement from an adult child many years before death;
• Did not conduct adequate enquiries — by failing to contact the surviving partner or obtain full information before deciding;
• Acted in bad faith or for an improper purpose; or
• Made a decision that was unfair or unreasonable in all the circumstances (this is the broader standard available through AFCA).

It is worth noting that Bailey v Palombo [2020] NSWSC 1209 illustrates how property arrangements — including jointly held assets passing by survivorship — are relevant to assessing what provision a surviving spouse or partner has actually received. A trustee who does not account for the full picture of what each claimant has received or will receive may be making an incomplete assessment.

§6Step-by-Step: How to Formally Dispute a Death Benefit Decision

Step 1 — Request the trustee's written decision and reasons

Before you can lodge a formal complaint, you need the trustee's written decision. Contact the fund in writing and request a full explanation of how the decision was made, what factors were considered, and what documents were relied upon. Keep records of all correspondence.

Step 2 — Lodge an Internal Dispute Resolution (IDR) complaint

Every super fund is required to have an IDR process. Lodge your complaint in writing, clearly stating:

• Your relationship to the deceased and your basis for claiming dependant status;
• The specific grounds on which you say the decision was wrong or unfair; and
• The outcome you are seeking (e.g., a full review, a share of the benefit, or reconsideration of particular factors).

The fund must acknowledge your complaint promptly and respond within 45 days (confirm current timeframes with the Australian Securities and Investments Commission, as regulatory requirements can change).

Cost: IDR is free.

Step 3 — Escalate to AFCA if the IDR response is unsatisfactory

If you are unhappy with the IDR outcome — or if the fund does not respond in time — you can lodge a complaint with the Australian Financial Complaints Authority (AFCA). AFCA is a free, independent external dispute resolution service that has the power to overturn trustee decisions it considers unfair or unreasonable.

Critical deadline: You generally must lodge your AFCA complaint within 28 days of receiving the IDR written response. Missing this deadline may result in your complaint being declined.

AFCA's superannuation division can consider both legal error and broader fairness — giving claimants a wider basis to challenge than a court would typically apply. The process involves submitting evidence, written submissions, and potentially a case conference. AFCA can direct the trustee to pay a benefit to a person the trustee had excluded, or to vary the allocation.

Typical duration: AFCA superannuation complaints typically take between 6 and 18 months to resolve, depending on complexity.

Cost: Free for complainants.

Step 4 — Court proceedings (if AFCA is not suitable or is unsuccessful)

In some circumstances — particularly where large sums are involved or where AFCA lacks jurisdiction — court proceedings may be necessary. These are expensive and time-consuming, and you should obtain independent legal advice before proceeding. Confirm current jurisdictional thresholds with the relevant court or a solicitor.

§7Common Mistakes and Misconceptions

Assuming the will controls the super. As discussed above, it does not. This is the most pervasive misconception in death benefit disputes.

Waiting too long. The 28-day AFCA deadline after the IDR response is unforgiving. If you receive a written IDR decision, seek advice immediately.

Not claiming de facto status. Surviving partners sometimes assume they do not qualify because the relationship was not formally registered or publicly known. Evidence of cohabitation, shared finances, and mutual support can establish de facto status even without a formal registration.

Assuming a lapsed nomination is still valid. Many Australians do not realise that standard binding death benefit nominations lapse after three years if not renewed. A lapsed nomination gives the trustee full discretion.

Failing to gather evidence early. Bank statements showing financial interdependency, utility bills, joint lease agreements, photographs, and statutory declarations from mutual friends are all valuable. This evidence can deteriorate or become harder to access over time.

Not understanding the trustee's duty. The trustee owes a fiduciary duty to all potential beneficiaries and must act impartially. If you have evidence the trustee was provided with incomplete or inaccurate information by another claimant, that is a relevant ground.

§8Relevant Legal Framework

Superannuation death benefits in Australia are governed primarily by federal legislation — including the Superannuation Industry (Supervision) Act 1993 and related regulations — as well as each fund's trust deed. State and territory succession laws (such as the Succession Act 2006 (NSW)) are relevant to determining who qualifies as a dependant or eligible person in some circumstances. Because laws vary between jurisdictions and funds, always confirm the applicable rules with the relevant fund or a qualified superannuation solicitor.

§9Real Cases Showing the Key Issues

The cases below illustrate how courts have grappled with questions that arise in death benefit disputes. They are cited here to show the complexity of the issues involved — not to predict any particular outcome in your matter.

In Watson Wyatt Superannuation Pty Ltd v Oberlechner & 2 ors [2008] NSWSC 272, the court examined how trust deed provisions govern a trustee's obligations when allocating a death benefit, confirming that the deed's terms are foundational to any trustee decision.

In Reynolds v Bonnici [2017] NSWSC 828, the court considered whether a will could direct a superannuation death benefit and confirmed that the super fund's rules — not the deceased's testamentary wishes — govern the trustee's discretion.

In Sun v Chapman [2022] NSWCA 132, the Court of Appeal examined how the question of whether a de facto relationship existed at the time of death is itself a contestable factual issue, underscoring the importance of presenting evidence of the relationship carefully and comprehensively.

In Bailey v Palombo [2020] NSWSC 1209, the court's analysis included how property that passes outside the estate — including jointly held assets — is relevant to the broader financial picture, which is similarly relevant when a trustee is assessing what each claimant has already received or will receive from the deceased's affairs.
