Superannuation death benefit disputes have been on a quiet upward trend for several years. The combination of rising super balances, more complex family structures, and tighter expectations on trustee discretion has produced a steady stream of contested decisions. The first half of 2026 has continued the trajectory and produced some specific developments worth incorporating into estate planning advice.

This is a working read on where the field sits and what’s worth factoring into client conversations now.

The volume picture

The Australian Financial Complaints Authority data for the past year shows super death benefit complaints continuing to climb. The headline volume isn’t dramatic in absolute terms but the year-on-year increase is real and consistent. The SCT-era predecessor body and AFCA both saw similar trajectories. The pattern is structural, not a blip.

The complaints break down across familiar categories. Disputes between adult children and second spouses about who should receive the benefit. Disputes between separated partners and the deceased’s estate. Disputes about whether a binding death benefit nomination was valid. Disputes about the trustee’s exercise of discretion when the nomination was non-binding or absent.

The categories haven’t changed dramatically over the past five years. The volumes have.

What the recent decisions show

A handful of AFCA determinations through late 2025 and into early 2026 have been worth noting for estate planners.

Several decisions have firmed the expectation that trustees give meaningful weight to documented evidence of the deceased’s wishes when exercising discretion in the absence of a binding nomination. The “look at the nomination form, look at the will, exercise discretion” pattern of older trustee practice is being pushed toward “consider all available evidence of the deceased’s intentions and document the reasoning carefully.”

This sounds like a small change but the implications are real. Trustees who issue determinations with thin reasoning are being challenged successfully on procedural grounds. The expectation of considered, documented decision-making has tightened.

A separate stream of decisions has continued to address the validity of binding death benefit nominations. The technical requirements for validity — proper witnessing, proper renewal, proper specification of beneficiaries — continue to trip up nominations made without legal advice. The advice to clients to have the nomination prepared with the same care as a will is more important than it used to be.

The interaction with family law has been a notable theme. Several decisions have addressed the position of separated but not divorced spouses, of de facto partnerships of contested duration, and of complex blended family arrangements. The trustees’ job in these situations is genuinely difficult and the decisions reflect that.

The blended family pressure

The single largest driver of the increased volume of disputes is the changing demographic profile of the deceased members. More members are dying with second or third partnerships. More members have adult children from earlier relationships and step-children from current ones. More members have complex family arrangements that don’t map cleanly onto the dependant categories the legislation contemplates.

The trustees are being asked to navigate disputes that the legislative framework wasn’t really designed for. The decisions look reasonable case by case but the cumulative effect is that the outcomes are less predictable than they were when family structures were simpler.

For estate planners, the implication is that the binding nomination has become more important than the older “let the trustee work it out” approach. A clear, valid, current binding nomination is the most reliable way to direct a death benefit. The discretion-based approach increasingly produces outcomes that families weren’t expecting.

What clients are getting wrong

The estate planning conversations I’ve been having through 2025-26 keep surfacing the same client misunderstandings.

Many clients believe their will controls their super. It doesn’t, except where the trustee directs the benefit to the estate, which itself is a discretionary outcome unless specifically nominated. Clients who put detailed super provisions in their will are often surprised that those provisions don’t have direct legal effect.

Many clients believe their nomination is binding when it isn’t. The non-lapsing binding nominations need to be made on the specific form the fund requires, properly witnessed, and validly renewed if not non-lapsing. A nomination that doesn’t meet the technical requirements is treated as non-binding regardless of what the client intended.

Many clients haven’t updated their nominations after major life events. Marriages, divorces, separations, deaths of nominated beneficiaries, births of new dependants — all of these should trigger a review of the nomination. Most clients don’t do this proactively.

Many clients don’t understand the dependant test. The benefit can only be paid directly to dependants or the estate. Adult children are not necessarily dependants for super law purposes. Friends, charities, and unrelated parties can only receive the benefit through the estate.

These misunderstandings are not new. They have become more consequential as super balances have grown and family structures have become more complex.

What’s working in 2026 estate planning

The estate planning practitioners doing this well in 2026 are taking specific approaches.

Comprehensive nomination reviews as a standard part of the estate planning engagement, not as an afterthought. The nomination is treated as a separate and critical document, with its own renewal cycle and review schedule.

Clear documentation of the client’s intentions in case the nomination later becomes contested or invalid. A well-documented file of the client’s stated wishes can support a trustee’s discretionary decision in the direction the client intended.

Coordination with the broader estate plan. The will, the nomination, the family agreement, the binding financial agreement — these need to work together. Disputes often arise because they don’t.

Education of the client about what super is, how it differs from estate assets, and why the nomination matters. The clients who understand this are far less likely to leave a problematic situation behind.

Working with the right superannuation funds where flexibility allows. Not all funds support all nomination types. Clients with complex estate plans sometimes benefit from being in funds that support reversionary pensions, child pension nominations, and other specific structures.

What to watch

Several things are worth watching through the rest of 2026.

The AFCA approach to discretion challenges will probably continue to firm. Trustees that want to avoid being overturned on review need to invest in the quality of their decision-making and documentation.

The legislative response, if any, to the structural pressure on the dependant test. Various reform proposals have been floated; none have moved meaningfully through the parliamentary process. That could change.

The interaction between super death benefits and the various forms of digital and crypto assets that increasingly form part of estates. The current legal framework doesn’t handle these cleanly.

The continued evolution of family structures and the pressure that puts on trustee discretion frameworks designed for an earlier demographic reality.

The super death benefit area has moved from a routine estate planning checkbox to a substantive estate planning issue in its own right. The clients who get good advice and follow it are well protected. The clients who don’t are leaving messes for their families that didn’t need to happen.
