Joint Tenancy vs Tenants in Common: The Hidden Trap That Cost One Melbourne Family $340K
Last month, we sat across from Rebecca, a Toorak mother whose husband had died six months earlier. She was confused, angry, and heartbroken — not just about losing Michael, but about discovering that their property ownership structure had effectively disinherited his two children from his first marriage. Their $1.8 million family home, held as joint tenants, passed entirely to Rebecca by operation of law. Michael's carefully crafted will, which left his children a 40% share of the property, was completely irrelevant.
This is the hidden trap in joint tenancy vs tenants in common estate planning that catches hundreds of Victorian families every year. The way you hold property title determines who gets what when you die — regardless of what your will says.
How Joint Tenancy Overrides Your Will
Most married couples in Victoria hold their family home as joint tenants without understanding what this actually means. They assume it's just a technical detail their conveyancer sorted out years ago.
Here's what that actually means in practice: when one joint tenant dies, their share automatically passes to the surviving joint tenant(s). This happens by operation of law under the Property Law Act 1958 (Vic), and your will cannot change it.
Take Rebecca and Michael's situation. Despite Michael's will clearly stating his intention to leave his children a share of the family home, the joint tenancy structure meant Rebecca inherited 100% of the property automatically. The will was powerless to override this.
"But we made wills specifically to provide for his kids," Rebecca told us, holding back tears. "How is this possible?"
It's possible because property law operates independently of succession law. The right of survivorship in joint tenancy is absolute.
The Alternative: Tenants in Common
Tenants in common ownership works differently. Each owner holds a distinct share of the property — it could be 50/50, 60/40, or any other split. When a tenant in common dies, their share forms part of their estate and passes according to their will.
If Michael and Rebecca had held their property as tenants in common, Michael's 50% share would have passed according to his will. His children would have received their intended inheritance, and Rebecca would have kept her 50%.
The legal difference seems minor, but the practical consequences are enormous.
When Joint Tenancy Makes Sense
We're not anti-joint tenancy. For many couples, it's exactly the right choice. Joint tenancy works well when:
- Both partners want the survivor to inherit everything
- There are no children from previous relationships
- The couple has similar asset levels and earning capacity
- They want to avoid probate on the property
Consider Sarah and Tom, a Camberwell couple we worked with last year. Both had never been married before, they had two young children together, and their $950K property was their main asset. Joint tenancy made perfect sense — whoever survived would need the full value of the home to care for their children.
But for blended families, joint tenancy can create devastating unintended consequences.
The Blended Family Trap
Blended families need to think differently about property ownership. In 2026, over 35% of Victorian marriages involve at least one partner who has been married before, yet most still default to joint tenancy without considering the implications.
Here's another scenario we see regularly: David, a carpenter from Essendon, married Helen five years ago. David has a 19-year-old daughter, Emma, from his first marriage. Helen has no children. Their modest $680K home is held as joint tenants.
David assumes his will, which leaves Emma 25% of his estate, will provide for his daughter. But if David dies first, Helen inherits the entire property automatically. Emma gets nothing from the main family asset.
This isn't about Helen being greedy or uncaring — she may genuinely want to provide for Emma. But life gets complicated. What if Helen remarries? What if she develops dementia and needs expensive care? What if she simply forgets David's verbal promises about providing for Emma?
We've seen these situations play out dozens of times. The surviving spouse almost always has good intentions initially, but circumstances change.
The Tax Trap Most People Miss
Here's where most families get blindsided: the tax implications of changing property ownership structures. This is exactly why our team integrates legal and financial expertise — the tax consequences can be enormous.
Converting from joint tenancy to tenants in common can trigger capital gains tax and stamp duty implications. In Victoria, any transfer of property interest — even between spouses — needs careful tax planning.
For example, if Rebecca and Michael had tried to convert their joint tenancy to tenants in common after their property had appreciated significantly, they might have faced unexpected tax consequences. The timing and method of any ownership restructure matters enormously.
This is where stamp duty on inherited property in Victoria can create additional complexity, particularly when beneficiaries need to restructure ownership after death.
How to Make the Change
If you currently hold property as joint tenants and want to change to tenants in common, you'll need to "sever" the joint tenancy. This involves:
- Preparing a Notice of Severance under section 88 of the Property Law Act 1958 (Vic)
- Registering the severance with Land Use Victoria
- Updating your wills to reflect the new ownership structure
- Considering any tax implications of the change
The process isn't complex, but it needs to be done correctly. We've seen DIY attempts that created more problems than they solved.
Beyond Property: The Bigger Estate Planning Picture
Property ownership is just one piece of your estate planning puzzle. Many clients come to us focused solely on their will, not realising that how they hold assets often matters more than what their will says.
Your superannuation, for instance, operates under completely different rules. Most people assume their super automatically follows their will, but it doesn't. Binding death benefit nominations can override your will entirely.
This is why we always recommend starting with a comprehensive estate planning review. Understanding how all your assets pass to beneficiaries — through wills, survivorship, nominations, or trusts — gives you the full picture.
Our estate planning checklist covers all seven critical areas that most families miss, including property ownership structures, superannuation nominations, and powers of attorney.
The Business Owner Complication
If you own a business or investment properties, the joint tenancy vs tenants in common decision becomes even more complex. Business assets, family trusts, and multiple properties all interact with your estate plan in different ways.
We worked with a Richmond couple last year who held their family home as joint tenants but their three investment properties as tenants in common. Their estate plan had to account for both ownership structures, plus the husband's share in a plumbing business.
The complexity multiplied when they wanted to ensure the wife could continue living in the family home while still providing for his adult children from his previous marriage. The solution involved restructuring some properties and setting up testamentary trusts, but it required careful coordination between property law, tax planning, and estate planning.
What We Wish Every Family Understood
The biggest mistake we see families make is treating property ownership as a set-and-forget decision. They choose joint tenancy or tenants in common when they buy their first property together, then never revisit the decision as their family circumstances change.
But life evolves. You have children, get remarried, accumulate wealth, start businesses, or inherit assets. Your property ownership structure should evolve with your circumstances.
Regular will updates are crucial, but reviewing your property ownership structures is equally important. We recommend families review both every three to five years, or after major life events.
Don't Let Property Law Override Your Wishes
Rebecca's story didn't have to end the way it did. If Michael had understood how joint tenancy worked, he could have restructured their property ownership to align with his estate planning goals. His children could have received their intended inheritance, and Rebecca could still have had security in the family home.
Instead, a well-intentioned estate plan was derailed by a property ownership structure that nobody properly explained to them.
The law won't bend to accommodate your good intentions. But with proper planning, you can structure your affairs so the law works in your family's favour, not against it.
