Supersize Your Super: Why a Binding Death Benefit Nomination Matters

November 3, 2026

What is a binding death benefit nomination?

A BDBN is a direction made by you to your superannuation fund specifying how your superannuation death benefit should be paid upon your death.

If you have a valid BDBN in place, the trustee is generally required to follow your direction and distribute the death benefit accordingly.

What happens if I don’t have a binding death benefit nomination?

Superannuation is held on trust by the trustee of the fund for your benefit, meaning it does not automatically form part of your estate.

If there is no valid BDBN in place, the trustee will typically decide who receives your death benefit. Depending on the circumstances, the benefit may be paid to your spouse, children, another dependent, or your estate.

Importantly, the terms of your Will only govern the distribution of your superannuation death benefit if the benefit is paid to your estate.

Particular care should be taken where blended families, stepchildren, former spouses, or complex family circumstances exist. Without appropriate planning, the distribution of your superannuation may not reflect your intentions.

Wait…There’s tax on my super?

Many people are surprised to learn that superannuation death benefits can have different tax consequences depending on who receives them.

For this reason, a carefully considered nomination can form an important part of effective estate and tax planning. Benefits paid to a spouse, minor child or other tax dependent may receive favourable tax treatment, while tax liabilities can arise where benefits are paid to an estate or certain non-dependent beneficiaries.

Validity Matters

A BDBN is only effective if it is valid.

While nominations can be challenged, disputes commonly focus on whether the BDBN was properly executed and complied with the requirements of the superannuation fund and relevant legislation.

Depending on the fund’s rules, a valid nomination may require:

• specific forms to be used;
• the nomination to be signed and dated correctly;
• independent witnesses;
• proper lodgment with the fund; and
• eligible beneficiaries to be nominated.

Even minor errors can result in a BDBN being declared invalid, leaving the trustee to decide who receives the benefit. For this reason, it is important to ensure any nomination complies with the specific requirements of your superannuation fund.

Review Your Nomination Regularly

Marriage, divorce, the birth of children, changes in financial dependency, amendments to superannuation fund rules, and changes to your estate plan can all affect whether your nomination remains appropriate and effective.

Some superannuation funds require binding nominations to be renewed periodically, often every three years, while others allow non-lapsing nominations. Regular reviews help ensure your nomination remains valid and aligned with your intentions.

Yes, we can help with that

For many of us, our superannuation and life insurance benefits will form a significant portion of our estates. Yet without a valid binding death benefit nomination, there is no guarantee those benefits will be distributed as intended.

A well-considered nomination, coordinated with your Will and broader estate plan, can provide certainty for your loved ones and help minimise delays, disputes, and unintended outcomes.
