With housing affordability becoming increasingly challenging, it’s common for parents to step in and help their children purchase a home or improve their financial position. While this support is usually given with the best of intentions, problems can arise later, especially when a relationship breaks down and there is no clear record of whether the money was a gift or a loan.
The good news? Most disputes can be avoided with a few simple steps taken before the money is transferred.
Why disputes occur
Parents and couples often shy away from discussing formal arrangements because:
- It feels uncomfortable
- They trust each other
- They don’t want to “make it weird”
- They assume the relationship will never end
But when things go wrong, unclear informal arrangements often become the most contentious and expensive issues in a separation.

Five practical steps to avoid future disputes
1. Put it in writing…the right way
A lawyer‑drafted loan agreement is the simplest and strongest way to avoid confusion about intention. A proper agreement should clearly detail:
- The amount provided;
- Who the borrowers are;
- Repayment terms;
- Interest payable (even if nominal);
- Consequences if the relationship ends.
2. Keep records of repayments
Repayments, even irregular or small, help show that a genuine loan existed. Evidence might include:
- Bank transfers;
- Receipts;
- Text messages acknowledging repayment;
- References to repayments in financial documents.
This shows the arrangement was not purely informal.
3. Consider registering security
If parents truly intend the money to be repaid, taking security is one of the strongest indicators. Options can include:
- Lodging a caveat on the title;
- Registering a mortgage;
- Creating a PPSR registration.
These steps signal a clear expectation of repayment and protect parents’ interests if the relationship breaks down.
4. Seek legal advice before funds change hands
A short discussion with a lawyer can save families thousands later. Lawyers can:
- Prepare a loan agreement;
- Draft a statutory declaration;
- Advise whether a binding financial agreement (BFA) is suitable;
- Guide parents on protecting their position.
Most disputes arise simply because the conversation never happened.

Where prenups (binding financial agreement) can help
A simple and often-overlooked way to avoid these disputes is through a Financial Agreement or commonly referred to as a “prenup”.
A Financial Agreement can clearly set out:
- Whether parental money is a gift or loan;
- What happens to the funds if the relationship ends;
- How contributions from parents will be treated;
- How assets are divided on separation.
This can provide certainty for both partners and protect parents who want to help but don’t want their contribution lost in a separation. Having this clarity upfront prevents many of the arguments that arise years later when memories differ and documentation is missing.
Why these steps matter
We regularly see situations where:
- Parents step in to help with a deposit;
- No document is created;
- Years later, after separation, everyone remembers things differently.
Not only does this increase stress, but it can also greatly increase the legal costs required to resolve the dispute.
Taking simple steps early can avoid these outcomes entirely.
Conclusion
Parental financial assistance is a generous and important way many families support each other. Without clear planning, it can become a source of conflict if a relationship breaks down. By documenting intentions, keeping records, taking security where appropriate, and considering a Binding Financial Agreement, families can protect themselves and avoid unnecessary disputes.
