Guarantor Default on Your Credit File — Can It Be Removed?

Quick Answer: Yes — a guarantor default can be removed from your credit file if the credit provider failed to follow the correct process under the Privacy Act 1988, most commonly by not sending a valid Section 21D notice to the guarantor's current address before listing. Australian Credit Solutions has successfully challenged guarantor defaults on accepted cases where notice was defective, the amount was wrong, or the debt had already been paid. Outcomes depend on individual case assessment.

Being a guarantor felt like the right thing to do — helping a family member or partner get the loan they needed. Now there's a default on your credit file for a debt that wasn't even yours to start with, and lenders are turning you down. That's exactly the kind of situation our team sees regularly.

The good news: guarantor defaults are frequently listed incorrectly. The legal requirements that apply to the borrower apply equally to you, and a missed step on the creditor's part can be legitimate grounds for removal.

What Is a Guarantor Default, and How Does It End Up on Your Credit File?

A guarantor default is a negative listing recorded on the guarantor's own credit file — not just the borrower's — when a guaranteed loan falls into default. Under the Privacy Act 1988 (Cth), Part IIIA, credit providers may report a default against any person who is a "consumer" for credit reporting purposes, and guarantors are treated as consumers in relation to the guaranteed facility.

So if you guaranteed your sibling's personal loan or your adult child's car finance, and they stopped making repayments, the lender can — and often does — list the default on your credit file as well as theirs. Equifax, Experian and illion each receive these reports. The listing sits on your file for five years from the date it was recorded, regardless of whether the underlying debt has since been repaid.

What many guarantors don't realise is that the credit provider must follow an identical procedural process for the guarantor as it does for the borrower. Skip a step on notice, address, timing or amount — and the listing becomes challengeable. That distinction matters enormously for anyone in this situation.

Understanding what is on your file starts with reading how credit files work — it explains exactly what credit providers can report and on what timeline.

Does the Creditor Have to Notify You Before Listing a Guarantor Default?

Yes — before listing a default on a guarantor's credit file, a credit provider must send a Section 21D notice under the Privacy Act 1988 (Cth) directly to the guarantor at their current or last known address, at least 14 days before the listing is made. The Privacy (Credit Reporting) Code 2025, which commenced on 25 March 2025, reinforces this requirement.

A Section 21D notice must:

• Be sent to you personally — not just to the borrower or the loan security address,
• Go to your last known residential address, which the credit provider must take reasonable steps to update, and
• Allow at least 14 days before the default is recorded on your file.

The most common failure point is that the creditor sends the Section 21D notice to the borrower's address — or to the address associated with the loan account — rather than to the guarantor's separate home address. If you never received that notice, or if it was sent somewhere the lender knew was outdated, that is a procedural defect.

A defective or missing Section 21D notice is the single most common basis for removing a default, whether you are the borrower or the guarantor. For a full explanation of how this works across all default types, see our guide on defaults listed without proper notice.

Your full rights under the credit reporting framework are also set out in the Privacy Act credit repair guide.

What Are the Grounds for Removing a Guarantor Default?

Under the Privacy Act 1988, a default listing must be accurate, complete, and the result of a procedurally correct process. For a guarantor, the grounds for challenging the listing include:

A correctly listed default — one where every procedural step was followed, the amount is accurate, and valid notice was given — cannot be removed by anyone, including us. We say that plainly because it matters: ACS accepts cases only where there are genuine grounds, which is why we carry a 98% success rate on accepted cases. The number reflects selectivity at intake, not a guarantee on any specific listing.

If you are unsure whether the amount on your file is correct, our guide on defaults listed for the wrong amount explains how amount-based disputes work.

How Long Does a Guarantor Default Stay on Your Credit File?

A default listing — whether you are the borrower or the guarantor — is retained for five years from the date it was recorded, under the standard retention periods in the Privacy Act 1988. The OAIC (Office of the Australian Information Commissioner) oversees the credit reporting framework and confirms these timeframes on its website.

Paying the debt after a default has been listed does not remove it or shorten the five-year retention period. A paid default is updated to reflect "paid" status, but the listing itself remains until the retention period expires — unless the listing is successfully disputed and found to be incorrect, or the credit provider voluntarily agrees to remove it.

If the guarantee was given more than five years ago, the default may have already dropped off your file. You can get a free copy of your credit file from each of Equifax, Experian and illion once per year — you are entitled to this under the Privacy Act 1988, and it costs nothing. Check the listing date carefully: that is the clock that determines when the five years runs out.

How Do You Dispute a Guarantor Default?

Disputing a guarantor default in Australia follows two clear paths: a free DIY route through the credit reporting body at no cost, and a lawyer-led route through Australian Credit Solutions (ASIC ACL 532003) when the creditor resists.

The DIY path (free, and worth starting here):

1. Pull your credit files from Equifax, Experian and illion. Each may hold different information — check all three.
2. Identify the default: who listed it, the date, the amount, and whether there is a "paid" notation.
3. Lodge a formal dispute directly with the credit reporting body that holds the listing. Under the Privacy Act 1988, the bureau must investigate and refer your dispute to the credit provider within 30 days.
4. If the credit provider rejects your dispute, escalate through their internal dispute resolution process, then to an external dispute resolution scheme for an independent ruling.

MoneySmart (moneysmart.gov.au) has plain-English guidance on disputing credit file errors. The OAIC also publishes its own consumer fact sheets on credit reporting rights.

If you are also managing the underlying debt and facing financial difficulty, the National Debt Helpline (1800 007 007) provides free financial counselling and can help you think through your options before you take any formal steps.

The lawyer-led path (when the DIY route stalls or you want professional handling from the start):

If the credit provider or bureau refuses to correct the listing after a formal dispute — or if you want the matter assessed and handled by a lawyer with authority to push back — that is where default removal services become relevant.

Australian Credit Solutions is ASIC-licensed (ACL 532003) and operates under the Privacy Act 1988 with a lawyer's authority to correspond with creditors, prepare formal dispute submissions, and escalate through external dispute resolution where needed. We assess each case at no cost before committing to it. If there are no genuine grounds, we tell you so upfront rather than taking a case we cannot reasonably win.

Representative Example (Details Changed for Privacy)

The situation: Jasmina guaranteed her brother's personal loan in 2023. He stopped making repayments in mid-2024. In early 2026, Jasmina discovered a default on her Equifax file when she was declined for a home loan — it was the first she had heard of any problem with the loan.

The process: ACS reviewed Jasmina's credit file and the creditor's notice records. The Section 21D notice had been sent to her brother's address — not to Jasmina's residential address, which the lender had on file from her original guarantee application. The notice was procedurally defective for the guarantor.

The outcome: The listing was disputed on notice grounds and successfully removed within 45 days. Jasmina subsequently obtained home loan pre-approval. Individual results vary and depend entirely on the specific facts of each case.

Frequently Asked Questions

Can a lender put a default on my credit file if I was only the guarantor, not the borrower? Yes — under the Privacy Act 1988 (Cth), Part IIIA, credit providers can report defaults against guarantors as well as borrowers. Australian Credit Solutions regularly sees guarantor defaults listed by banks, finance companies and consumer lenders. However, the creditor must follow identical procedural steps for the guarantor as for the borrower, including issuing a valid Section 21D notice to the guarantor separately.

Does the bank have to send me a notice before listing a guarantor default on my credit file? Yes — a credit provider must send a Section 21D notice to the guarantor personally, to their current or last known address, at least 14 days before listing the default under the Privacy (Credit Reporting) Code 2025 (commenced 25 March 2025). If that notice was not sent, sent to the wrong address, or sent less than 14 days before listing, the default may be challengeable on procedural grounds.

What if I never knew the borrower had stopped paying? This is one of the most common grounds Australian Credit Solutions investigates. If the Section 21D notice was sent to the borrower's address rather than yours — or to an address the lender knew was no longer current — that is a procedural defect under the Privacy Act 1988. It may be sufficient grounds to have the guarantor default removed, subject to individual assessment.

How long does a guarantor default stay on my credit file in Australia? A guarantor default stays on your credit file for five years from the date it was listed, under the standard retention periods in the Privacy Act 1988, as confirmed by the OAIC. Paying the underlying debt does not remove the listing or shorten the five-year period — it only updates the listing's status to "paid."

Can a guarantor default stop me getting a home loan or car loan? Yes — an active default on your credit file, even as a guarantor, is a significant negative listing and most mainstream lenders will decline an application. Some specialist lenders consider applications with paid defaults in limited circumstances, but terms are typically more restrictive. If the listing is successfully removed, you may qualify for mainstream lending again. See our guide on how long after a default is removed you can get a home loan.

Can I get a guarantor default removed myself for free? Yes — you can dispute the listing directly with the credit reporting body (Equifax, Experian or illion) at no cost. They must refer your dispute to the credit provider and investigate within 30 days under the Privacy Act 1988. If the creditor disputes your claim, you can escalate to an external dispute resolution scheme. MoneySmart's website explains the steps in plain English.

What if the amount listed on the guarantor default is wrong? An incorrect amount is a separate ground for correction under the Privacy Act 1988. The amount listed must accurately reflect the outstanding balance at the time the default was recorded. If the debt was partially settled before listing, or if the amount includes fees that should not have been included, that may constitute an inaccuracy — distinct from the notice issue. See our guide on defaults listed for the wrong amount.

What is a Section 21D notice and why does it matter for guarantors? A Section 21D notice is the formal default notice a credit provider must issue before listing a default on any credit file, including a guarantor's. It must be sent to the individual personally — not just to the borrower — at their current or last known address. A missing or misdirected Section 21D notice is the most common basis on which Australian Credit Solutions successfully challenges guarantor defaults. More detail is in our Section 21D notice guide.

Does ACS handle guarantor default cases? Yes — Australian Credit Solutions (ASIC ACL 532003) assesses guarantor default cases under the same framework as borrower defaults. If there are valid grounds under the Privacy Act 1988 — most commonly a defective Section 21D notice, an incorrect amount, or a paid debt still listed — we pursue removal through the appropriate channels. Our 98% success rate applies to accepted cases only; we do not take cases where we cannot identify genuine grounds.

Can a correctly listed guarantor default ever be removed? No — if every procedural requirement was satisfied, the amount is accurate, and the guarantor received valid notice at their correct address, the listing is lawful and cannot be removed by anyone. ACS makes this clear at the free assessment stage. If you have a listing you believe was made correctly but want certainty, our guide on incorrect defaults on your credit file explains the distinction between an unlawful listing and a correctly made one.

What to Do Next

Start with your credit file. Get a free copy from Equifax, Experian and illion, find the guarantor default, and check three things: when it was listed, what amount is shown, and whether you received a Section 21D notice at your home address before it was listed. If you never got that notice, or if the amount looks wrong, those are concrete grounds to pursue.

If the DIY dispute path does not resolve it, or you want a lawyer to read the file and assess the case before you invest more time, book a free credit assessment with Australian Credit Solutions. We review the file, identify the grounds (if any), and give you a straight answer — at no cost and no obligation to proceed.
