Family loan agreements are becoming increasingly common in Australia, particularly where parents help children buy property, support a family business, or provide financial assistance during difficult times.
While these arrangements are often made with trust and goodwill, problems often arise when these matters are handled too casually and expectations are not clearly documented. For example, a parent may loan their child a lump sum towards their first home deposit but, without clear terms being established, estate disputes may arise regarding whether or not the funds are explicitly a loan or a gift.
A family loan agreement documents these terms and helps you and your family avoid these serious legal and relationship issues. This guide explains how family loan agreements work, why they matter, and the key actions to take to protect everyone involved.
A family loan agreement is a written legal document that sets out the terms of a loan between family members. It confirms that money provided is a loan, not a gift, and clearly explains how and when it must be repaid.
This agreement can include details such as the amount, repayment schedule, interest terms (if any), and the consequences if a default occurs. Unlike verbal promises, a written agreement helps prove the transaction’s intent, especially in estate matters or tax audits.

Family loans that are not documented often result in problems later, particularly when circumstances change.
Common risks include disputes over whether the money was a loan or a gift, disagreement about repayment terms, complications during divorce or separation, issues when a lender or borrower passes away, and conflict between siblings or beneficiaries in an estate.

Family Loan Agreements are commonly used by parents lending money to children or grandchildren, families assisting with first home purchases, relatives funding renovations or investments, families supporting business start-ups, and executors or beneficiaries dealing with loans within an estate.
While not every small financial favour requires documentation, a family loan agreement should be considered if:
Furthermore, if money is being lent with an expectation of repayment, legal advice is strongly recommended, especially within families, to avoid the escalation of disputes in future.
Without a properly documented family loan agreement, known as an informal family loan, disputes can often arise over:
Many family disputes do not start with bad intentions; they start with assumptions. Having the conversation early, with professional guidance, is often far easier than trying to resolve issues later.
A properly drafted family loan agreement clarifies expectations upfront, reduces emotional and financial stress later, protects family relationships, provides certainty if circumstances change, and avoids costly disputes and legal action.

Family loan agreements are often entered into with trust and good intentions, but good intentions alone are often not enough when circumstances change. Relationship breakdowns, financial pressure, or estate disputes can quickly turn an informal arrangement into a costly and emotional issue.
Putting a clear, properly drafted family loan agreement in place is not about creating distance – it is about protecting relationships, providing certainty, and avoiding misunderstandings down the track. When expectations are documented upfront, families are far more likely to avoid conflict later.
At Argon Law, we regularly assist individuals and families with tailored family loan agreements that are practical, legally sound, and aligned with broader considerations such as property ownership, estate planning, and asset protection.
We can help you:
Whether you are lending money, borrowing from family, or reviewing an existing arrangement, obtaining the right legal advice early can save significant stress, expense, and conflict later.
If you’re considering a family loan or want to ensure an existing arrangement is properly documented, Argon Law can guide you through the process with clarity and confidence.
A. Trust is important, but circumstances change. A loan agreement helps preserve trust by setting clear expectations upfront and reducing the risk of misunderstandings or conflict later.
A. No. Money provided to a family member is not automatically a gift, but there is a legal presumption that a transfer of funds from parent to child is a gift unless there is a clear agreement to the contrary. However, if there is no written family loan agreement, it can be difficult to prove that the money was intended to be repaid. A properly drafted agreement helps clearly establish whether funds are a loan or a gift and defeats the presumption of Advancement.
A. The key difference is repayment. A loan involves an expectation that the money will be repaid, whereas a gift does not. Without clear documentation, it can be difficult to prove whether money was intended as a loan or a gift, particularly in estate or relationship disputes.
A. While verbal agreements can sometimes be legally enforceable, they are hard to prove and often lead to disputes. A written family loan agreement provides clarity, certainty, and stronger legal protection for everyone involved.
A. A well-drafted family loan agreement typically covers the loan amount and purpose, repayment terms, interest (if any), security, and what happens if circumstances change.
A. Yes. Family loans can be interest-free if that reflects the parties’ intentions. Even where no interest is charged, it is still important to document the arrangement, so expectations are clear and enforceable. However, charging interest may be appropriate in some situations, particularly where tax, asset protection, or fairness between beneficiaries is a concern. Legal and financial advice can help determine the best approach.
A. This depends on the terms of the agreement. A family loan agreement can set out what happens if repayments are missed, including whether repayment periods can be extended or whether the lender can take further action. Addressing this upfront avoids uncertainty and conflict later.
A. Yes. In some cases, a family loan can be secured against property or another asset, particularly where large sums are involved. Secured loans offer additional protection but require careful legal drafting.
A. A family loan does not automatically disappear on death. It may form part of the deceased’s estate, either as a debt owed to the estate or a liability that must be repaid. Clear documentation helps ensure the loan is dealt with properly and reduces disputes between beneficiaries.
A. Yes. Family loan agreements can usually be varied if circumstances change, provided all parties agree. Any changes should be documented in writing to avoid confusion or disputes.
A. Yes. Courts can and do enforce family loan agreements, provided they are properly drafted and show a clear intention to create a loan. Well-documented agreements offer significantly stronger protection.
A. Generic templates may not address important issues such as property purchases, estate planning or family law risks. A tailored agreement provides greater certainty and better reflects your specific situation.
