Going guarantor on a home loan in QLD: the risks before you say yes

Your kid’s found a place. The bank says they’ll lend – but only if Mum and Dad go guarantor. It feels like a no-brainer, right? You’re just helping out. Here’s the bit nobody spells out at the kitchen table: going guarantor isn’t a character reference. You’re putting your own home on the line. So before you sign anything, here’s what it actually means in Queensland – and how to protect yourself.

TLDR

• Going guarantor means you’re legally on the hook for someone else’s loan if they can’t pay – often with your own home as security.
• It’s not “a bit” of the loan. In most cases you guarantee the whole debt, plus interest and the bank’s costs.
• If the borrower defaults, the bank can come after you – and potentially sell your house to recover the money.
• Your own borrowing power takes a hit too, because lenders count the guarantee as a liability.
• Australian banks legally require guarantors to get independent legal advice before signing – and that’s a good thing, not a hoop.
• Empire Legal acts for the guarantor (never the bank), explains it in plain English, and signs off the certificate. Call 07 3088 7675.

What “going guarantor” actually means

When you go guarantor, you’re promising the lender that if the borrower stops paying, you’ll cover it. Simple in theory. The sting is in the detail.

Most guarantees are for the full loan amount, not a token slice. Many are “all monies” guarantees, which can cover future lending too, not just this one loan. And the vast majority are secured – meaning the bank registers a mortgage over your property as backup. If things go bad, that’s the asset they’ll look to.

People hear “guarantor” and picture vouching for someone. The law sees it very differently: you’re a backstop the bank can call on, with your house behind the promise.

The risks worth losing sleep over

You could lose your home. This is the big one. If the borrower defaults and there’s a mortgage over your place, the lender can ultimately force a sale to get their money back. It happens.

You’re liable for more than the loan. Default interest, legal costs, enforcement costs – they can all land on you.

It can wreck your own plans. Want to refinance, buy an investment, or downsize? Lenders treat your guarantee as a liability sitting against your name, which can shrink how much you can borrow.

It can strain the relationship. Money between family is delicate. If repayments stop, you’re not just out of pocket – you’re in an awkward spot with someone you love.

How to protect yourself before you sign

Get clear on the numbers. How much are you guaranteeing? Is it capped at a set figure, or open-ended? Can you guarantee only part of the loan (a “limited guarantee”) instead of the lot? Banks won’t always offer it, but it’s worth asking.

Understand the exit. When does the guarantee end? Often it stays in place until the loan is repaid or the borrower has enough equity to release you. Don’t assume it drops off in a year.

And get your own advice – from a solicitor acting for you, not the bank. Lenders require it anyway (more on that in our guide on why the bank makes you get independent legal advice). At Empire Legal we only ever act for one party, so when we advise a guarantor, we’re 100% in your corner – the same principle we apply to every matter, which you can read about in why we never act for both sides.

If the money is really a family loan dressed up as a guarantee, there may be a cleaner way to do it. Sometimes a proper loan agreement protects everyone better than a bank guarantee. We can talk you through both.

So, should you do it?

Plenty of guarantees work out perfectly fine – the borrower pays, the equity builds, the guarantee gets released, everyone’s happy. The point isn’t “never do it.” It’s “go in with your eyes open.” Know the worst case, make sure you could survive it, and get advice before you put pen to paper.

Frequently asked questions

What does going guarantor on a home loan mean? It means you legally promise the lender that you’ll repay the loan if the borrower can’t. In most cases you guarantee the full debt, and the bank takes a mortgage over your own property as security.

Can I lose my house by going guarantor? Yes. If your property is used as security and the borrower defaults, the lender can ultimately force a sale of your home to recover the debt. This is the single biggest risk of going guarantor.

Am I liable for the whole loan or just part of it? Usually the whole loan, plus interest and costs, unless you negotiate a limited guarantee capped at a set amount. Always check exactly what you’re guaranteeing before you sign.

Does going guarantor affect my own borrowing power? Yes. Lenders treat the guarantee as a liability against your name, which can reduce how much you’re able to borrow for your own purchases or refinancing.

When does a guarantee end? Typically when the loan is fully repaid, or when the borrower has built up enough equity for the lender to release you. It doesn’t automatically expire after a set period – you usually have to request release.

Do I need a solicitor to go guarantor? Yes. Australian lenders require guarantors to obtain independent legal advice before signing. Empire Legal provides that advice and signs the lender’s certificate – acting for you, not the bank.

Is a guarantee the same as a family loan? No. A guarantee backs someone else’s bank loan; a family loan is money you lend directly. Sometimes a documented loan agreement is a safer way to help family than going guarantor. We can advise on both.
