In 2026, the “Australian Dream” has shifted. For many families, buying a separate home for aging parents or adult children is no longer financially viable. Instead, we are seeing a boom in Multi-Generational Living—specifically, parents funding the construction of a Granny Flat or extension on their child’s property.
It seems like the perfect solution: the parents get to downsize close to family, and the children get an increase in their property value. But without a Granny Flat Agreement or formal loan structure, this “win-win” can turn into a financial nightmare.
The “Fixture” Fallacy
The single biggest misconception is ownership. Parents often believe that because they paid for the Granny Flat, they own it.
The Legal Reality: In Australia, whatever is attached to the land belongs to the land. As soon as that Granny Flat is built on your child’s title, it legally becomes their asset, not yours.
This creates two massive risks:
- The Divorce Disaster: If your child and their partner separate, the Family Court views the entire property (including your Granny Flat) as an asset of the marriage. Your $200,000 contribution could be split with your child’s ex-partner, leaving you with no home and half your capital gone. Read more about protecting assets from divorce here.
- The Centrelink Trap: If you transfer money to build the flat without a formal Granny Flat Agreement, Centrelink may view this as a Gift. This could trigger the “Deprivation Rules,” reducing your Age Pension entitlements for five years because you gave away assets exceeding the gifting limit. Learn how to avoid the Centrelink gifting trap.
Loan vs. Life Interest: How to Protect Yourself
To stop your money from disappearing, you generally have two structural options. Both require formal documentation.
1. The Formal Granny Flat Interest (For Centrelink)
A Granny Flat Agreement (or Interest) is a specific legal arrangement recognised by Centrelink. It involves transferring assets (money) in exchange for a guaranteed “right of residence” for life.
- The Pro: If structured correctly, the money you spend is not counted as a gift for Centrelink testing.
- The Con: It can be complex to set up and requires a specific deed to be drafted.
2. The Formal Family Loan (The Asset Protector)
For many families, a simpler and more flexible option is to treat the construction cost as a Secured Loan.
- How it works: You lend the $200,000 to your child to pay for the build. You sign a formal loan agreement (using a platform like Chipkie) and potentially register a caveat over the property title.
- The Result: The money is now a liability of the child.
- Divorce Shield: If they divorce, the loan must be repaid to you before the remaining assets are split. The ex-partner cannot claim your $200,000.
- Flexibility: If the property is sold later, the loan is simply repaid to you.
Why a “Handshake” is Financial Suicide
Many families avoid paperwork because “we trust each other.” But trust doesn’t stop a divorce, a bankruptcy, or a family feud.
If you are paying for a renovation on a property you do not own, you are essentially donating your life savings to your child’s future legal disputes. A verbal agreement is worthless in these scenarios. You need a paper trail that proves exactly what the money was for and that it is owed back to you or grants you a legal right to be there.
