Many young Australians are struggling to get a foot on the property ladder due to high deposit requirements and lending criteria. We speak to a lot of parents who are looking for a way to help their kids and serving as a guarantor can help bridge the gap. It is not, however, risk-free. This article will help you understand what it means to be a guarantor, how it works, and what the financial and legal risks are. It can be a wonderful thing to do for your children, helping them on the path to homeownership and security, but if done without expert legal oversight and a complete understanding on both sides, it can be financially detrimental to the guarantor.

What does it mean to be a guarantor?
Acting as a guarantor means taking on a legal commitment to support your child’s home loan. Essentially, if your child is unable to meet their mortgage repayments, you could be required to cover part or all the outstanding loan. This isn’t just a promise, it’s a formal agreement with the lender, backed by law, that carries real financial consequences.
There are different types of guarantees to suit various circumstances:
- Full Guarantee: This type of guarantee covers the entire loan. If your child defaults, the lender can pursue you for the full amount owed, including interest, fees, and legal costs. While this provides the bank with maximum security, it also exposes you to the highest level of risk.
- Limited Guarantee: A limited guarantee restricts your liability to a specific portion of the loan, often tied to the deposit or a set monetary amount. This approach gives parents a way to help without putting their entire financial situation at risk.
It’s also important to understand the difference between guaranteeing the deposit versus the whole loan. Guaranteeing just the deposit means your responsibility is capped at that initial contribution, whereas guaranteeing the entire mortgage could leave you liable for the full property value if repayments stop.
Being a guarantor is legally binding. Signing a guarantee creates a formal contract with the lender, enforceable in court. It isn’t something you can casually back out of, and it will appear on your credit record, potentially affecting your borrowing capacity. For this reason, legal advice is essential before agreeing to become a guarantor, to ensure you fully understand the implications and risks involved.
QLD guarantor home loan, how it works in practice
The process of a parent acting as a parent guarantor in Queensland might sound complicated, but in practice, it usually follows well-trodden steps. Imagine a young couple or single person ready to buy their first home but struggling to meet the lender’s deposit requirements. They apply for a home loan, providing their income, expenses, and credit history as usual.
When the lender reviews the application, they might see that the borrower falls short of the required deposit or that their income is too low to qualify for the full loan. At this point, the lender may suggest involving a guarantor, typically parents, to provide additional security. This doesn’t automatically mean the parent will cover the loan, but it gives the bank legal assurance that part of the mortgage is backed by someone with more financial stability.
Parents can then agree to guarantee either part of the mortgage or just the deposit portion. For example, if a property requires a 20% deposit and the child can only provide 10%, the parent might guarantee the remaining 10% of the property’s value. In some cases, parents may choose to provide a limited guarantee covering only a portion of the loan, reducing their financial exposure.
From the lender’s perspective, having a guarantor reduces their risk. It allows them to approve a larger loan or extend credit that the borrower might not otherwise qualify for. Essentially, the guarantor acts as a safety net, giving the borrower access to homeownership while providing the bank with additional security.
For instance, on a $600,000 property, a 20% deposit equals $120,000. If the child can provide $60,000, the parent might guarantee the remaining $60,000. This arrangement helps the borrower secure the property while limiting the parent’s liability to the agreed portion.
By understanding the practical steps and financial mechanics, parents can make informed decisions before committing to this type of guarantee. Being a guarantor for a child’s loan carries significant financial risk. If the child defaults, parents can be held fully liable for the debt, which can have serious consequences for personal finances.
Acting as a guarantor can also impact your credit rating and borrowing capacity. Even if your child meets their repayments, the lender may treat the guarantee as an existing liability, potentially limiting your ability to obtain credit for yourself.
There’s also the potential for family tensions. Financial problems can create stress and strain relationships, particularly if repayments become difficult or legal action is required.
The legal side can be complex. As a guarantor, you take on joint liability, meaning the bank can enforce repayment directly against you. It’s important to understand that once you sign, the arrangement is not reversible without the lender’s consent.

Protecting yourself as a mortgage guarantor Queensland
Before signing as a guarantor, it is essential to seek legal advice. A qualified lawyer can explain your rights and obligations, outline the risks involved, and help you understand the full implications of the guarantee. This step is crucial to avoid costly mistakes or unforeseen liabilities.
One way to limit your financial exposure is through a limited guarantee. This sets a cap on the amount you could be called on to repay, helping you manage the risk and protect your personal assets. Your lawyer can guide you on whether this option is available and suitable for your circumstances.
It is also important to review your child’s financial situation carefully. Assess their income, budgeting, and the loan’s affordability to understand whether the arrangement is realistic. Being informed about their capacity to meet repayments can reduce the likelihood of future problems.
Consider protective strategies for your own assets. Options such as equity release or other forms of asset protection can provide an extra layer of security, ensuring that your personal finances are safeguarded in the event of a default.
Finally, documenting family arrangements can help prevent misunderstandings. Setting out expectations and responsibilities clearly in writing, even informally, can reduce conflict and provide a reference point if disagreements arise. While these measures do not remove your legal obligations, they help create clarity and protect relationships within the family.
By taking these steps, seeking legal advice, limiting exposure, reviewing finances, protecting assets, and documenting arrangements, you can support your child while minimising the risks to yourself. Acting carefully and proactively is key to being a responsible guarantor.
Alternatives to acting as a Queensland first home guarantor
If you’re concerned about the risks of acting as a guarantor, there are several alternatives that can help your child get into the property market. One common option is a gifted deposit, where you provide funds upfront to help cover the deposit without taking on ongoing liability for the loan.
Another approach is a shared equity arrangement, where you contribute to the property purchase in exchange for a share of the ownership. This can reduce the loan amount required and spread the financial risk more evenly.
Co-borrowing, or taking out a joint loan, is another option. While this can help your child secure a mortgage, it comes with its own risks: both parties are fully responsible for repayments, and any missed payments can affect everyone’s credit rating.
Finally, consider government schemes such as the First Home Loan Deposit Scheme or other state and federal incentives. These programs can reduce the deposit required or provide financial support, helping first-home buyers enter the market without requiring a family guarantee.
By exploring these alternatives, parents can support their children’s property goals while limiting personal financial exposure and avoiding the complexities of a guarantor arrangement.

Final words on being a guarantor
Becoming a Queensland property purchase guarantor can help a loved one into home ownership, but it also carries serious obligations and risks. Always seek independent legal and financial advice first, and consider alternatives and protections, such as capped (limited) guarantees, before you commit. This is a personal decision that balances supporting family with safeguarding your own financial security; take the time to weigh both the emotional and financial stakes.
