Parents often want to help their children financially, especially when it comes to buying a first home or covering major expenses. With property prices what they are, the “Bank of Mum and Dad” has become one of the country’s biggest informal lenders but generosity without paperwork is exactly where family disputes tend to start.
A bank of mum and dad loan agreement can make this help safe and fair for everyone involved. Without clear terms, these loans can cause stress, disputes, or even legal battles later on.
Having a written bank of mum and dad loan agreement gives both parents and children peace of mind, ensuring the money is treated properly and the relationship stays strong. Seeking legal guidance from our family law team before lending money to family members can help protect your financial interests and avoid future disputes.
What Is a Bank of Mum and Dad Loan Agreement and Why Is It Important?
A bank of mum and dad loan agreement is a legal document that sets out the details of money lent from parents to their children. It explains how much money is being loaned, when it should be paid back, and any interest or conditions attached.
This type of agreement is important because it prevents misunderstandings. If the money is just handed over without paperwork, it might later be seen as a gift rather than a loan.
In fact, there’s a general legal presumption that money passed from a parent to a child is a gift unless it’s clearly documented otherwise, meaning the paperwork isn’t just a formality, it’s often what determines whether the money is ever seen again.
This can create problems during separation, divorce, or disputes with other family members. A formal bank of mum and dad loan agreement helps everyone know exactly where they stand.
How Can a Bank of Mum and Dad Loan Agreement Protect Parents and Children?
A written bank of mum and dad loan agreement protects both sides by putting the loan terms in writing.
For parents, it provides reassurance that their money is treated as a loan and not forgotten. It also makes clear how and when repayments should be made. If the child separates from their partner, the agreement can show that the money is still owed to the parents rather than being counted as part of a couple’s shared assets.
Courts generally look for a written agreement, evidence of repayments, and whether any security was taken before accepting that an advance was truly a loan.
For children, the agreement avoids uncertainty and ensures there is no confusion about what is expected of them. It can also help show banks and lenders that the financial help has been properly structured.
In this way, a bank of mum and dad loan agreement protects the family relationship as well as the finances. Understanding how a de facto or married partner’s claim over a property you own can play out can help families structure these loans more effectively from the outset.
The “Gift Letter” Trap
Many parents run into trouble when a bank asks them to sign a gift letter (sometimes called a gifting certificate or statutory declaration) as part of their child’s home loan application. Banks often require this because it’s simpler for their lending assessment than recognising a second loan sitting behind their own mortgage.
The problem is that signing a gift letter is a declaration that the money is non-repayable. If the child’s relationship later breaks down, that signed letter can be used against the parents, and a genuinely intended loan can be treated as a gift in family law proceedings, leaving the parents with no legal standing to recover their money. This scenario is entirely avoidable with the right advice and the right documents in place before any money changes hands.
What Key Terms Should Be Included in a Bank of Mum and Dad Loan Agreement?
When drafting a bank of mum and dad loan agreement, certain details should always be included. These may vary depending on the situation, but some common terms are:
- Loan amount – the exact sum being borrowed.
- Repayment terms – how the money will be repaid, whether in instalments or in a lump sum.
- Timeframe – the period over which the loan is to be repaid, including a specific maturity date and any provision for extension.
- Interest – whether the loan will carry interest, and if so, how it will be calculated. Many family loans are structured as interest-free with repayment only due on sale of the property, so the terms need to say so explicitly.
- Security – whether the loan is secured against property or other assets, such as a registered mortgage or caveat.
- Default provisions – what happens if the borrower cannot repay on time.
- What happens on sale, refinance, separation, or death of either party – so there’s no ambiguity if circumstances change.
- Whether the loan is made personally or via a family trust or company – which carries its own tax consequences (see below).
Having these terms clearly written helps avoid confusion. It also shows that the bank of mum and dad loan agreement is a serious arrangement, not just a casual understanding.

Choosing the Right Security: Registered Mortgage vs Caveat
If real property is involved, parents generally have two main options for securing repayment:
- A registered mortgage offers the strongest protection. It ensures the loan must be repaid before the property can be sold or refinanced. If a bank already holds the first mortgage, parents can register a second mortgage, though they’ll rank behind the bank if the child defaults.
- A caveat puts other parties on notice of the parents’ interest in the property, but it offers weaker protection than a registered mortgage and can be more easily challenged or removed.
Rather than taking security over the property, some families instead use a simple deed of acknowledgement of debt, signed by the child (and sometimes their partner), confirming the loan and its terms. This can be a useful backup, though it typically offers less protection than registered security.
Why the Statute of Limitations Matters
Even a properly documented loan can become unenforceable over time. In most Australian states, there’s a limitation period (commonly six years) for recovering a simple contract debt. If years pass without any written acknowledgement of the loan, parents can lose their right to recover it entirely.
Even if everyone still agrees the debt exists. Building in periodic written acknowledgements of the debt is a simple way to keep the loan enforceable for as long as it’s outstanding.
Tax and Division 7A Considerations
If the funds are lent personally, any interest the parents charge is generally treated as taxable income. If the loan comes from a family company or trust rather than directly from the parents, Division 7A of the Income Tax Assessment Act 1936 imposes strict rules around minimum interest rates, maximum loan terms, and minimum yearly repayments. Getting this wrong can trigger deemed dividends and unexpected tax bills, so specialist tax advice alongside your family lawyer is essential whenever a business structure is involved.
What Risks Arise Without a Formal Bank of Mum and Dad Loan Agreement?
If there is no bank of mum and dad loan agreement, both parents and children face several risks.
Parents may struggle to prove that the money was a loan if the matter ends up in court. This could mean they lose their right to repayment. The money could also be treated as part of a child’s assets in a divorce settlement, leaving the parents with no way to claim it back.
Children may also face issues if the loan is not documented. Without clear terms, disagreements with parents may arise about how much is owed or when it should be repaid. This can damage family relationships.
A lack of a formal bank of mum and dad loan agreement can also create problems with banks, as lenders may not accept undocumented loans as part of a financial plan.
The Guarantor Trap
Some parents go a step further and act as guarantor on their child’s home loan rather than (or as well as) lending money directly. This can expose the parents’ own assets, including their home, if the child falls behind on repayments. Anyone considering a guarantor arrangement should get independent legal advice from our team specifically about the guarantee before signing anything, so they fully understand the extent of their exposure.
Estate Planning: What Happens If a Parent Dies Before the Loan Is Repaid?
It’s easy to overlook what happens to a family loan if a parent passes away while it’s still outstanding. Without an update to the parents’ will, an outstanding loan to one child can create real unfairness between siblings, or confusion for executors trying to wind up the estate. Reviewing your will alongside your loan agreement helps make sure the arrangement is treated fairly across the whole family and reduces the risk of disputes over the estate.
Alternatives to a Straight Loan
A loan agreement isn’t the only way to structure family financial support. Depending on the circumstances, families sometimes consider:
- Gifting the money outright, paired with a Binding Financial Agreement between the child and their partner, so the gift is protected if that relationship later ends, similar in spirit to the protections discussed in Can My Girlfriend Take Half My House in Australia?. Independent legal advice from separate lawyers is mandatory for both parties for such an agreement to be enforceable.
- Jointly purchasing the property, though this brings its own complications, including potential capital gains tax exposure and the parents being jointly liable for any bank finance.
The right structure depends heavily on individual circumstances, so it’s worth discussing your options with a family lawyer before any money is transferred.
Why Should You Seek Legal Advice Before Finalising a Bank of Mum and Dad Loan Agreement?
Creating a bank of mum and dad loan agreement is not just about writing down terms on paper. The agreement should be clear, enforceable, and fair to both sides.
By seeking legal advice, parents and children can ensure the agreement is tailored to their needs and reflects their intentions properly.

Protecting Families With Clear Agreements
Helping children financially is a generous and meaningful step for many parents. However, without a written plan, that help can lead to confusion and conflict.
A properly drafted bank of mum and dad loan agreement is one of the best ways to ensure money matters do not get in the way of family bonds. By setting clear terms, everyone knows what is expected, and parents and children alike can move forward with confidence.

FAQs
How to make a loan agreement legally binding?
For a family loan agreement to be legally binding and enforceable, it generally needs to be in writing, clearly identify the parties and the loan amount, set out the repayment terms and any interest, and be signed and dated by everyone involved. Verbal or “handshake” agreements can technically be enforceable in some circumstances, but they’re very difficult to prove and rarely stand up if a dispute reaches court. Where the loan is linked to a relationship or a property purchase, having each party obtain independent legal advice before signing and taking formal security such as a registered mortgage where real property is involved, further strengthens the agreement’s enforceability.
What are common mistakes in loan agreements?
Common mistakes include not putting the loan in writing, failing to clearly state the amount borrowed, leaving repayment dates or interest unclear, and not explaining what happens if repayments are missed. For family loans, it is also important to clearly establish that the money is a loan rather than a gift, particularly if the parties may later become involved in a family law or property settlement dispute.
How much notary for loan agreement?
This depends heavily on where you are and what the loan involves. In Australia, by contrast, a private family loan agreement generally doesn’t need to be notarised to be valid. What matters more is that it’s properly drafted, signed, and (where security is involved) registered with the relevant land titles office. If you’re unsure what formalities apply to your situation, it’s best to check with a family lawyer or conveyancer before signing.
How to make a simple loan agreement?
A simple family loan agreement should still cover the essentials: the names of the lender and borrower, the loan amount, whether interest applies and how it’s calculated, the repayment schedule or trigger for repayment (such as sale of a property), what happens if a payment is missed, and what happens if the parties’ circumstances change (separation, refinance, or death). Even a short, plain-language document covering these points is far better than no agreement at all, but for anything involving a house deposit, a guarantor arrangement, or funds from a company or trust, it’s worth having a family lawyer review or draft the agreement so it actually holds up if it’s ever tested.
