Are loan agreements between family members legally binding in Queensland?

A loan between family members — whether between parents and adult children, siblings, or other relatives — is as legally enforceable as any commercial loan, provided the basic requirements of contract law are met. The family relationship does not diminish the legal obligation; however, it does create a practical challenge: courts will scrutinise whether the transfer of money was truly a loan or simply a gift.

When Is a Family Loan Legally Binding?

For a family loan to be enforceable, three elements of contract law must be present:

1. Offer and Acceptance: One party must offer to lend money and the other must accept those terms.
2. Consideration: Money is transferred in exchange for a promise to repay — this satisfies the consideration requirement.
3. Intention to Create Legal Relations: This is the critical element in family lending. Courts apply a presumption that transfers within a family context are gifts, not loans. You must rebut this presumption by demonstrating a genuine shared intention that the money would be repaid.

A written loan agreement directly establishes the intention to create legal relations. Without one, you are relying on circumstantial evidence to rebut the gift presumption — a significantly harder evidentiary position.

The Gift Presumption Problem

Queensland courts recognise a common law presumption that money transferred between closely related family members — particularly from parent to child — is a gift rather than a loan. If the borrower later claims the money was a gift, the burden shifts to the lender to disprove that claim on the balance of probabilities (that is, to show it is more likely than not that the transfer was a loan).

Evidence commonly used to rebut the gift presumption includes:

• A written loan agreement or deed signed by both parties
• Bank transfer descriptions that reference “loan,” “to be repaid,” or similar
• Text messages or emails in which the borrower acknowledges the debt or discusses repayment
• Proof of partial repayments, which strongly implies acknowledgment of a debt
• Witness statements from anyone present when the loan was agreed

Practical Risks Unique to Family Lending

Several features of family lending create risks that do not arise in commercial lending:

Repayment terms are often vague. Many family loans are made “on demand” with no fixed repayment date. This is legally valid but can cause problems if the lender delays asking for repayment, since the Limitation of Actions Act 1974 (Qld) provides that a debt becomes statute-barred six years after it falls due. If the loan was “on demand” and no demand was ever made, the six-year period may not have started running — but this depends on the precise circumstances.

Security is rarely taken. A family lender almost never registers a security interest against the borrower’s property. If the borrower becomes insolvent, the family lender becomes an unsecured creditor and is unlikely to recover anything unless they registered a PPSR interest against the borrower’s vehicle or other personal property, or took a mortgage or caveat over real property.

Relationship dynamics delay legal action. Family relationships often cause lenders to delay making formal demands, gathering evidence, or commencing proceedings. Each year of delay is a year in which evidence becomes harder to locate and the limitation period runs.

How to Protect a Family Loan

The steps are simple but frequently overlooked:

1. Get it in writing before the money moves. Even a one-page signed loan agreement covering the amount, date, repayment terms, and interest (if any) is sufficient.
2. Confirm by text or email. If a written agreement is not practicable, at minimum send a confirming message immediately after the transfer: “As agreed, I have transferred $X to you as a loan to be repaid by [date].” Ask them to confirm. Their reply is contemporaneous written evidence.
3. Keep bank records. Retain your bank statements showing the transfer and ensure the reference description clearly identifies the transaction as a loan.
4. Consider PPSR registration. If the borrower owns a vehicle, register a PPSR security interest against the VIN for around $7.40. This protects you if they sell the car or become insolvent.
5. Act promptly on any default. Do not allow the borrower to ignore the debt for years. Send a formal letter of demand and commence proceedings if necessary within the six-year limitation period.
