Imagine being denied a car loan because of a wrong default on your credit report — one that belongs to someone else entirely. It sounds impossible, but “mixed file” errors are more common than most Australians realise. Credit bureaus handle millions of records, and when they mix them up, it’s your financial future that pays the price.

How Someone Else’s Debt Ends Up on Your File

Credit reporting bodies like Equifax, Illion, and Experian match records using personal identifiers — name, date of birth, and address. But when two people share a similar name, a family address, or a common surname, the system can merge their records incorrectly.

We’ve seen a man denied finance because of a default belonging to his father — same surname, same address from years ago, completely different person. The bureau didn’t catch the error. The creditor didn’t verify it. And the innocent party was left explaining a debt he’d never heard of.

Common causes of mixed file errors include:

• Defaults belonging to a family member with a similar name
• Debts from a previous tenant at your address
• Records confused due to common Australian surnames
• Simple data entry errors by the credit bureau

The System Is Supposed to Be Accurate

Under the Privacy Act 1988 and the Credit Reporting Code, credit reporting bodies have a legal obligation to ensure the information on your file is accurate, up-to-date, and complete. The Office of the Australian Information Commissioner (OAIC) oversees compliance with these rules.

When a bureau allows someone else’s default to sit on your file, they’re potentially breaching their obligations. And when nobody checks, that mistake can linger for years — silently destroying your borrowing capacity.

Don’t Ignore It — Challenge It

Many people see a default on their file that doesn’t look right but assume nothing can be done. Others don’t even check their credit report until they’re knocked back for a loan. By then, the damage is already done.

As a law firm operating since 2009, MyCRA Lawyers has the legal tools to force credit bureaus and creditors to verify their records. We can issue demands under the Privacy Act, access discovery tools to obtain documentation, and hold the bureau accountable when their data is wrong. Our 91.6% audited success rate reflects how often these errors go uncorrected — until someone challenges them.

Don’t let someone else’s mistake cost you your financial future. Check your credit report, look for anything that doesn’t belong to you, and get expert legal help to have it investigated and removed.
