Estate planning for blended families: What are your options for property?

Blended families are increasingly common and they come in all forms. Whether you’re in a second relationship with children from a previous marriage, you share stepchildren with your partner, or you’ve both brought assets into a new family dynamic, one thing is clear:

Estate planning for blended families is more complex, especially when it comes to property.

As experienced estate lawyers in Victoria, we understand the sensitive balancing act of protecting your partner while also ensuring children from a previous relationship are not left out. Backed by our family law team, we provide complete support for blended families navigating property and inheritance decisions.

Here’s a breakdown of the key property-related estate planning options available to blended families and what to consider when choosing the right one for you.

The core challenge: Balancing competing interests

At the heart of estate planning in a blended family is a simple, yet emotionally charged question:

How do I make sure my partner has a home to live in, but my children ultimately inherit what I’ve built?

Without a clear and legally sound plan, this can lead to:

• Disputes between stepchildren and surviving spouses
• Unexpected outcomes under intestacy laws
• Costly litigation that reduces the value of your estate
• Hurt feelings or broken relationships

The good news is there are several tools and strategies available to ensure fairness, clarity, and peace of mind.

Option 1: Life interest or right to reside in the family home

This option allows you to:

• Leave your property to your children, but firstly allow your partner to live in the home for life (or a set period)
• After the life interest or right to reside ends (for example, upon death, leaving the property or remarriage), the property passes to your children

This strikes a balance between providing security for your partner while protecting the inheritance for your children.

Good for:

• Couples who want to preserve the family home for children from a previous relationship
• Avoiding forced sales while the surviving partner is still living

Consider:

• Maintenance costs, council rates, and who is responsible for upkeep
• Whether a right to reside should end if the partner remarries or enters a new relationship

Option 2: Owning property as tenants in common

Many couples assume they own their home as joint tenants, which means the property automatically passes to the surviving partner when one dies.

But for blended families, tenants in common may be a better option. It allows you to:

• Own a defined percentage of the property (e.g. 50%)
• Leave your share to someone other than your partner – such as your children, via your Will

This gives you flexibility and control over your portion of the home.

Good for:

• Preserving inheritance rights of children
• Couples with unequal contributions to the property

Consider:

• Whether the surviving partner can afford to stay in the home
• Whether you’ll combine this with a life interest or right to reside arrangement

Option 3: Mutual Wills agreements

A Mutual Wills Agreement is a legally binding promise between partners not to change their Will after one has died.

It’s used where:

• Each partner wants to leave their estate to the other initially, but
• They want to ensure children from both sides ultimately receive a share
• They’re concerned the surviving partner might later change their Will

Good for:

• Protecting intentions after the first partner dies
• Providing peace of mind in second marriages

Consider:

• They’re hard to undo – even if circumstances change
• They may cause tension or limit flexibility
• A mutual Will might still be challenged in Court on various grounds

Option 4: Using a Testamentary Trust

A Testamentary Trust is a trust created by your Will that can provide:

• Asset protection
• Tax-effective income distribution
• A flexible way to manage gifts to children or dependents

For blended families, testamentary trusts can be especially useful where:

• You want to provide some inheritance now and some later
• You want to delay inheritance until children reach a certain age
• You want to protect vulnerable beneficiaries (e.g. a child with a disability)

Good for:

• Larger estates or complex family arrangements
• Protecting assets from bankruptcy or relationship breakdowns

Consider:

• These trusts require careful drafting and a suitable trustee
• Ongoing administration after your death

Why proper advice matters

In blended families, a “simple Will” often won’t cut it. Even the best intentions can fall apart without a proper legal structure in place.

That’s why it’s essential to get advice from a lawyer who understands the modern realities of family dynamics, and who can tailor an estate plan to:

• Avoid conflict
• Respect your wishes
• Protect your partner and your children
• Keep things efficient and clear

There’s no one-size-fits-all solution. The right estate plan depends on:
