When clients come to us for estate planning, one of the most common sources of confusion is the Binding Death Benefit Nomination, or BDBN. Many people assume that their superannuation works just like their Will. They think they can leave their super to whoever they choose, only to discover that the law imposes strict limits on who can receive these benefits.
Firstly, what is a Binding Death Benefit Nomination?
A BDBN is a formal direction you give to the trustee of your superannuation fund. It tells them who should receive your death benefit when you die. The word “binding” is important here. A non-binding nomination can be considered by the trustee but ultimately ignored. A properly executed binding nomination is different. It requires the trustee to pay your death benefit to the people you have nominated.
When we refer to the trustee of your superannuation fund, we mean the entity that controls and manages the fund. For most Australians in large industry or retail funds, the trustee is a company appointed to run that fund. Examples include Australian Super and REST. You will never meet them personally. They are responsible for investing your money and handling administration. They also ultimately decide who gets your super when you die. If you have a self-managed superannuation fund, the trustees are typically you and perhaps other family members. That is a different arrangement altogether. For most people, the trustee is simply the company behind your super fund. A BDBN is your way of telling that company exactly where your death benefit must go.
Importantly, your superannuation does not automatically form part of your estate. The trustee of your super fund holds your benefits on trust, and when you die, they have a legal obligation to decide who receives those benefits. A BDBN gives you control over that decision rather than leaving it to the trustee’s discretion.
The Legal Framework
The authority for BDBNs comes from the Superannuation Industry (Supervision) Act 1993 (Cth) (“SIS Act”). Section 59(1A) of the SIS Regulations gives effect to these nominations, but the critical provisions are found in sections 10 and 10A of the Act itself. These sections define who qualifies as a dependant for superannuation purposes. This is where clients sometimes get a surprise.
Who Can You Actually Nominate?
Under the SIS Act, you can only nominate people who fall into very specific categories. Section 10 defines a dependant as your spouse, your child, or any person with whom you have an interdependency relationship.
Section 10A goes on to explain what constitutes an interdependency relationship, which requires that two people have a close personal relationship, live together, and one or each provides the other with financial support and domestic support and care.
The Act also allows you to nominate your legal personal representative, which means your estate. In plain English, your legal personal representative is the person who administers your estate when you die. If you have a Will, this is your executor. If you die without a Will, the court appoints an administrator to do this job. When you nominate your legal personal representative on a BDBN, you are directing the super fund trustee to pay your death benefit to whoever is handling your estate. That person then distributes the money according to your Will, or if you have no Will, according to the intestacy laws.
Let me give you a practical example. Take Leanne, for example. After her husband died, Leanne’s mother Margaret moved in to help raise the grandchildren. Years later, Leanne wants to provide for Margaret through her superannuation, so she completes a BDBN nominating her mother as the beneficiary. The problem is that Margaret is neither Leanne’s spouse nor her child. For the nomination to work, Margaret must qualify under an interdependency relationship as defined in section 10A of the Act.
Whether Margaret qualifies depends entirely on the actual circumstances of their arrangement.
Scenario one
Margaret has lived in Leanne’s home for the past eight years. Leanne pays for all household expenses and Margaret has no other income. Margaret does the cooking, manages the children’s school runs, and looks after the home while Leanne works full time. This arrangement almost certainly satisfies the interdependency relationship test. They share a residence, Leanne provides complete financial support, and Margaret provides substantial domestic support and care in return.
Scenario two
Margaret lives in her own unit across town. Leanne visits most weekends and occasionally takes her mother to medical appointments. Margaret sometimes babysits when Leanne needs help. Despite their close bond and mutual affection, this would likely not meet the legal definition. They do not live together, and the occasional assistance they provide each other likely falls well short of the financial and domestic support the Act requires.
Nominating your spouse or your child is straightforward because those relationships are legally defined and easy to prove. Interdependency relationships are far less clear-cut. The Act does not set out a precise threshold, and each case turns on its particular facts. If you are relying on an interdependency relationship to support a BDBN, you need to be satisfied that all four criteria are genuinely met, not just assumed.
The same applies to siblings, friends, charities, or anyone else who does not fit within the statutory definition of spouse, child, or someone with whom you have an interdependency relationship. The law is strict about this, and good intentions or moral obligations count for nothing if the legal criteria are not met.
What Happens When a Nomination Fails?
When a BDBN fails because the nominated person does not qualify as a dependant, or because the nomination was not properly executed, the trustee must exercise their discretion to determine who receives the death benefit. In many cases, particularly where there are no dependants, the benefit will be paid to your estate.
Payment to your estate means your superannuation will be distributed according to your Will. If you have no Will, the intestacy rules will apply instead. This can create problems. Your estate may face additional tax or delayed distribution. It may also face claims from creditors. These issues would not have arisen if the benefit had been paid directly to a dependant.
Prescribed Forms and Formalities
Most major superannuation funds have their own prescribed BDBN forms. They strongly recommend that members use these forms rather than creating their own documents. Australian Super, for instance, provides a specific BDBN form on its website. It includes detailed instructions about how to complete it correctly.
These forms exist for good reason. BDBNs have strict formal requirements. They must be signed and dated by you in the presence of two witnesses who are both over 18 and not nominated as beneficiaries. The witnesses must also sign the document. If these formalities are not followed exactly, the nomination may be invalid.
Many funds impose a three-year expiry on BDBNs in accordance with regulation 6.17A of the SIS Regulations. If you made a binding nomination five years ago and have not renewed it, there is a real risk it has lapsed and is no longer valid. Some funds do offer non-lapsing nominations that remain in effect until revoked, but you need to check your fund’s rules and the type of nomination you made.
Why This Matters for Your Estate Plan
The restrictive nature of BDBNs means that superannuation needs careful consideration in your overall estate plan. For many Australians, superannuation represents one of their largest assets, sometimes exceeding the value of the family home. Getting it wrong can undermine your entire estate plan.
If you want your superannuation to go to someone who is not a dependant under the SIS Act, you have one option. You must nominate your legal personal representative. This directs the benefit to your estate. You can then deal with the distribution in your Will. This may not be the most tax-effective strategy, but it may be necessary to achieve your wishes.
Getting It Right
The first step is understanding who qualifies as your dependant under the legislation. Your spouse and children will almost always qualify. Parents, siblings, and other relatives generally will not unless you have established an interdependency relationship with them.
Next, check with your super fund about their requirements. Obtain the current prescribed form and follow the instructions exactly. Make sure your witnesses are independent and that everyone signs and dates the document properly.
Finally, review your BDBN regularly, particularly after major life events like marriage, divorce, or the birth of children. Even if your fund does not require renewal every three years, circumstances change and your nomination should reflect your current intentions.
