Estate Planning for Blended Families

Why Blended Families Need Special Attention

Blended families — where one or both partners have children from previous relationships — face unique estate planning challenges. Without careful planning, your assets may not end up with the people you intend. The interaction between wills, superannuation death benefits, life insurance, and family provision claims can be complex. A standard will may not adequately protect both your current partner and your children from a previous relationship.

Wills and Testamentary Trusts

A well-drafted will is essential for blended families. Consider using a testamentary trust in your will — this allows your assets to be held in trust for your children while providing your current partner with income from the trust during their lifetime. This protects the capital for your children while supporting your partner. Without this structure, if you leave everything to your partner and they later update their own will, your children may receive nothing.

Superannuation and Binding Death Benefit Nominations

Superannuation does not automatically pass according to your will — it is paid to your beneficiaries according to your super fund's rules and any binding death benefit nomination (BDBN) you have in place. For blended families, a lapsing BDBN that is not renewed every three years could mean your super goes to unintended recipients. A non-lapsing BDBN can provide certainty. Consider splitting your super death benefits between your partner and your children to ensure both are provided for.

Life Insurance Ownership

Life insurance can be structured to ensure specific beneficiaries receive the payout directly. Holding life insurance inside super can complicate beneficiary distribution because super law restricts who can receive death benefits. Consider holding some life insurance outside super in your personal name, with a specific beneficiary nominated. This ensures the payout goes exactly where you intend, regardless of super laws.

What to Check in Your Advice Document

If you are in a blended family and receiving financial advice, your SOA, ROA, or CAR should address your estate planning needs specifically. It should discuss wills, testamentary trusts, BDBNs, and insurance ownership structures. Generic estate planning advice that does not consider the blended family dynamic may leave your estate exposed to legal challenges.

Why Blended Families Need Special Planning

Blended families — where one or both partners have children from previous relationships — face unique estate planning challenges. Without careful planning, the default legal rules for distributing assets when you die may not reflect your wishes. For example, if you die without a valid will (intestate), your estate is distributed according to a statutory formula that may not adequately provide for your current partner and children from a previous relationship simultaneously.

The core tension in blended family estate planning is balancing provision for your current partner with preserving assets for your children (from this and any previous relationship). A common approach is a "life interest" arrangement where your partner can use assets (such as the family home) during their lifetime, with the assets then passing to your children. However, this requires careful structuring to ensure both the partner's needs and the children's inheritance are protected.

Superannuation and Binding Death Benefit Nominations

Superannuation is often the largest asset in a person's estate, but it does not automatically pass according to your will. Super is held by the trustee of the super fund and is paid to your "dependents" (as defined under super law) or your legal personal representative (the executor of your will). Without a valid binding death benefit nomination (BDBN), the super fund trustee has discretion over who receives the death benefit.

A BDBN is a legally binding direction to your super fund about who should receive your death benefit. In blended families, a BDBN is essential to ensure your super goes to your intended beneficiaries, for example, to your current partner and children from a previous relationship in specified proportions. BDBNs typically need to be renewed every 3 years (for some funds) and must be witnessed correctly. A non-binding nomination provides guidance but the trustee retains discretion.

Testamentary Trusts and Asset Protection

A testamentary trust is a trust created by your will that comes into effect when you die. It offers significant advantages for blended families: the trustee of the testamentary trust can distribute income to beneficiaries in a tax-effective way (children under 18 can receive up to $18,200 per year tax-free), assets in the trust are protected from the beneficiaries' creditors and from claims by former spouses in family law proceedings, and the trust can continue for up to 80 years, providing long-term asset management.

For blended families, testamentary trusts can be particularly valuable for providing for minor children from a previous relationship. Instead of leaving assets directly to a minor (which requires a court-appointed trustee until age 18), a testamentary trust with a trusted adult as trustee ensures the assets are managed properly until the child reaches a specified age (such as 25 or 30).

Frequently Asked Questions

What happens if I die without a will in a blended family?
If you die intestate (without a will), the Succession Act of your state or territory determines who inherits your estate. The default rules generally favour your spouse and children, but the distribution may not reflect your wishes for a blended family. For example, your spouse may receive the entire estate, leaving nothing for your children from a previous relationship. Having a valid will is essential.

Can my ex-spouse claim my super after I die?
An ex-spouse is generally not entitled to your super death benefit unless they were financially dependent on you at the time of your death, or you had a binding financial agreement or court order that specifies super entitlements. A valid BDBN naming your current partner and children can help ensure your ex-spouse does not receive your super.

How often should I update my estate plan?
Review your estate plan whenever there is a significant life event: marriage, separation, divorce, birth of a child, death of a beneficiary, change in financial circumstances, or change in super laws. For blended families, annual reviews are recommended given the complexity of the arrangements and the potential for family circumstances to change.

What is a "life interest" and how does it work?
A life interest allows your partner to use an asset (such as the family home) for the rest of their life, after which the asset passes to your children or other beneficiaries. This can be structured through your will or a testamentary trust. The life interest ensures your partner is accommodated without disinheriting your children. However, life interests can create complexity if the partner wants to sell the home or move.
