Every year, thousands of Australian parents hand money to an adult child for a home deposit, a business, or a renovation, and almost none of them write it down. Then the child’s relationship ends, and the money is suddenly on the table. Protecting assets from de facto claims is not about hiding wealth or being cynical about your child’s partner. It is about making sure a court can see, years later, exactly what the money was: a loan to be repaid, or a gift that has now become part of a divisible asset pool.
Under the Family Law Act 1975, de facto couples have substantially the same property rights as married couples in every state and territory except Western Australia, which runs its own regime under the Family Court Act 1997 (WA). If your family money is undocumented, it is exposed.
Key Takeaways
- De facto partners can apply for a property settlement under the Family Law Act 1975, and the court divides a single pool of all assets and liabilities held by either party.
- An undocumented family advance is usually treated as a gift or a contribution, not a debt, which means half of it can effectively walk out the door.
- A properly documented parental loan, signed before the money moves and secured where possible, is the single most effective protection available to most families.
- Australia has no gift tax and no inheritance tax, so there is no tax penalty in documenting money as a loan rather than a gift.
- If the money is a loan, you cannot sign a lender’s gift letter or statutory declaration saying it is non-repayable. Doing so is fraud.
What happens to family money when a de facto relationship ends?
When a de facto relationship breaks down, the court identifies every asset and liability held by either party, assesses each person’s financial and non-financial contributions, considers future needs, and then decides what division is just and equitable. Family money sitting inside the couple’s home, without documentation, is simply part of that pool.
The four-step process courts apply looks like this:
- Identify the pool — all property, superannuation and debts of both parties, wherever held.
- Assess contributions — financial, non-financial, homemaking and parenting, including gifts from one side’s parents.
- Consider future needs — age, health, earning capacity, care of children.
- Test the outcome — is the result just and equitable in all the circumstances?
A gift from your parents is usually credited to you as a contribution on your side of the ledger. That helps, but it is a discretionary adjustment, not a dollar-for-dollar return. A genuine, provable loan is different: it comes off the top as a liability of the pool before anything is divided. That distinction is the whole ballgame in a family loan property settlement.
Does a documented parental loan really hold up in court?
Yes, but only if it looks like a real commercial arrangement rather than a document created after the relationship soured. Courts are openly sceptical of parental loans that surface for the first time during a property settlement. The evidence must show a genuine obligation to repay that existed from day one, and that both parties knew about it.
Our experience across the agreements Australians create is that the failures are almost always evidentiary, not legal. What a court looks for:
- A written agreement signed before the funds are advanced, naming both the child and the partner where both benefit.
- Clear repayment terms — either a schedule, or a demand clause, plus whether interest applies.
- A paper trail — bank transfers matching the agreement, and any repayments actually made.
- Security — a registered mortgage or a caveat over the property is far stronger than an unsecured promise.
- Consistent conduct — nobody described it as a gift in emails, loan applications or to the lender.
There is a trap that catches families every year. Debts can become statute-barred after a limitation period set by each state or territory’s limitation legislation, and a loan repayable “on demand” may start that clock running from the date of the advance. If your only enforcement mechanism has expired, the court may treat the money as a gift regardless of the paperwork. Check the current limitation period in your jurisdiction and diarise a review well before it lapses. A well-drafted family loan agreement should address this directly.
How do lender rules affect a deposit that is really a loan?
This is where families get into serious trouble. Australian lenders require a statutory declaration or gift letter confirming that a gifted deposit is non-repayable, and they typically want the funds genuinely saved or seasoned in the account. If the money is actually a loan, that declaration is false, and signing it is fraud.
The practical consequences of getting this wrong:
- A loan disclosed to the lender is assessed as a liability, reducing borrowing capacity and sometimes reducing the approved amount to the point the purchase fails.
- An undisclosed loan discovered later can trigger default, immediate repayment demands and referral for fraud.
- Some lenders will simply refuse a repayable family contribution as an acceptable deposit source, regardless of serviceability.
There is a real tension here: the structure that best protects the family money in a separation is the same structure that a lender may refuse. The answer is to have the conversation with a broker before the funds move, not after. Options include a loan with repayments deferred and formally acknowledged by the lender, a second mortgage, or a genuine gift paired with other protections. Never resolve the tension by mischaracterising the money on a declaration. If you are weighing this up, our guide to a Bank of Mum and Dad contract works through the trade-offs.
Also note the social security angle. Centrelink’s gifting rules allow $10,000 per financial year, capped at $30,000 over five financial years, before the excess is counted as a deprived asset for five years. This is a means-testing rule for payments such as the Age Pension, not a tax rule. Australia has no gift tax and no inheritance tax, as confirmed by the Australian Taxation Office, so documenting money as a loan carries no tax penalty.
What other tools actually protect family assets?
A documented loan is the foundation, but it is rarely the whole answer. Binding financial agreements, careful title structuring and disciplined record-keeping each do different work, and none of them is bulletproof on its own.
| Tool | What it does | Main weakness |
|---|---|---|
| Documented parental loan | Creates a liability that comes off the pool before division | Fails if undocumented, stale, or contradicted by conduct |
| Binding financial agreement | Lets a couple contract out of the court’s property jurisdiction | Can be set aside for non-disclosure, duress or defective legal advice |
| Tenancy in common | Records unequal shares and avoids automatic survivorship | Title share does not bind the family court’s discretion |
| Family trust | Separates legal and beneficial ownership | Can be treated as property or a financial resource of a party |
A binding financial agreement under Part VIIIAB of the Family Law Act 1975 can be made before, during or after a de facto relationship. Each party must receive independent legal advice and be given a signed statement confirming it. Skip that step and the agreement is vulnerable. Full and frank disclosure of assets is equally critical.
On trusts, be realistic. The High Court’s decision in Kennon v Spry established that assets held in a family trust can be brought into the pool where a party effectively controls them. Structure alone does not defeat a claim.
What should you do before the money leaves your account?
Take these steps in order, and take them before the transfer, not after. Retrospective paperwork is the single weakest form of evidence in a property settlement.
- Decide honestly whether this is a loan or a gift, and say the same thing to everyone, including the lender.
- Put it in writing with repayment terms, interest (or a clear statement that none applies), and signatures from both members of the couple.
- Register security where the money relates to property — a second mortgage or caveat lodged with the state land titles office.
- Transfer by bank transfer with a clear reference, never cash.
- Tell the mortgage broker the truth about the source and repayability of the funds.
- Review annually so the debt does not go stale, and keep all correspondence.
- Get advice from a family lawyer if a binding financial agreement is on the table. ASIC MoneySmart has useful background on lending money to family.
What else do people ask about protecting family money in a de facto split?
These are the questions we see most often from parents and adult children weighing up how to structure family financial support before a relationship becomes serious.
When does a relationship become de facto in Australia?
A couple is de facto when they live together on a genuine domestic basis without being married or related. Courts weigh the length of the relationship, shared finances, children and public reputation. There is a minimum period, plus alternative pathways involving a child or substantial contributions. Confirm the current criteria in the Family Law Act 1975.
Is there a time limit to bring a de facto property claim?
Yes. A strict limitation period runs from the date of separation, after which a party needs the court’s permission to apply. Western Australian de facto couples are governed by separate state legislation. Because the period is short and jurisdiction-specific, check the current deadline with a family lawyer as soon as a relationship ends.
Can a loan agreement be signed after the money was transferred?
It can, and it is better than nothing, but its weight is significantly reduced. Courts scrutinise agreements created after a relationship shows strain and may find the advance was always intended as a gift. Sign before the funds move, and keep contemporaneous emails or messages showing repayment was expected from the outset.
Does a written loan agreement guarantee the money is repaid?
No. It creates an enforceable obligation and strong evidence, but recovery still depends on the borrower having assets, the debt not being statute-barred, and any security being properly registered. Enforcement may require court action. Documentation dramatically improves your position without ever being an absolute guarantee.
Where should you start?
Protecting assets from de facto claims comes down to one unglamorous discipline: write it down before the money moves, and describe it the same way to your child, their partner, the lender and, if it ever comes to it, the court. Families who do this rarely end up in a dispute. Families who rely on a handshake and a shared understanding routinely do.
If you are about to advance money to an adult child, create a properly documented family loan agreement before the funds leave your account — it takes minutes, and it is the difference between a recoverable debt and a contribution to someone else’s property settlement.
