SMSF Will vs Binding Death Benefit Nomination (BDBN) for SMSFs

Writer: Grant AbbottGrant Abbott


A SMSF Will is a highly strategic and powerful legal document that forms part of the governing rules of an SMSF. It allows a member to dictate precisely how their superannuation death benefits are to be distributed upon their passing.


In contrast, a Binding Death Benefit Nomination (BDBN) is a traditional mechanism used by industry superannuation funds to direct the trustee to distribute death benefits in a specified manner.



Why is a SMSF Will Better than a BDBN?


  1. Legally Stronger and More Secure

    • Unlike a BDBN, which can expire after three years (unless the deed allows for non-lapsing nominations), a properly structured SMSF Will remains in force indefinitely.

    • A BDBN may not be followed if it does not meet strict legal requirements, whereas a SMSF Will, if properly drafted into the fund’s governing rules, becomes part of the trust deed and is enforceable​.

    • To date there has been no legal cases concerning SMSF Wills but more than 20, even High Court cases on BDBNs.


  2. Greater Strategic Flexibility

    • A SMSF Will allows for specific asset allocations, such as passing direct property or shares to beneficiaries rather than forcing the sale of assets to provide a lump sum​.

    • It enables members to structure their superannuation estate planning to provide income streams (pensions) to dependents, preserving wealth within the family.

    • BDBNs are generally locked down to passing specific percentages to the legal estate or death benefit dependant.


  3. Protection Against Family Provision Claims

    • Superannuation benefits do not automatically form part of an estate, meaning they are not subject to challenges under family provision laws.

    • A BDBN directs benefits but does not provide legal structuring to protect them from creditors or disgruntled family members.

    • A SMSF Will can include a Death Benefits Trust, providing asset protection from divorce settlements, bankruptcy, and litigation​.


  4. Tax Efficiency and Bloodline Protection

    • Death Benefit trusts within a SMSF Will can allow tax-effective income streaming to beneficiaries (particularly minors, who receive adult tax rates).

    • This ensures that superannuation remains within the bloodline and does not pass to ex-spouses, in-laws, or unintended parties​.


  5. Complete Control Over Death Benefit Payments

    • Trustees of SMSFs have significant discretion when dealing with death benefits. A BDBN merely directs the trustee, whereas a SMSF Will becomes part of the fund’s legal framework.

    • This control means members can implement auto-reversionary pensions, conditional payments, and staged distributions, ensuring dependents are financially secure over time​.


The Final Word: SMSF Will is the Clear Winner

A BDBN is outdated, restrictive, and prone to legal challenge.


A SMSF Will is a superior tool, providing:

Legal certainty

Strategic wealth distribution

Tax advantages

Bloodline protection

Asset protection from legal claims


Final Tip: If you have an SMSF, ensure your trust deed allows for a SMSF Will. If not, it's time for an upgrade to a modern LightYear Docs SMSF trust deed​. And if you would like legal support and help contact me grant@grantabbott.com
