Short answer: only if they're on the application. If you apply on your own, the lender checks your credit file, not your partner's. If you apply jointly, both credit files are checked and both of you are fully responsible for the loan. Your partner can still affect a sole application through your shared household budget, though.
Sole application
- Only your credit file is checked.
- Only your income counts towards affordability.
- But you'll be asked about your household, and lenders may consider how expenses are shared. If you split rent and bills, that can help. If you support a partner who has no income, that's factored in too.
Joint application
- Both credit files are checked. A default, recent missed payments or insolvency on either file can affect the outcome.
- Both incomes count, which can increase how much you can borrow.
- You're both jointly and severally liable. The lender can pursue either of you for the full amount, even if you separate.
Which is better?
| Situation | Often better |
|---|---|
| Your credit is good, your partner's has issues, and your income covers the loan | Sole application |
| Both credit files are clean and you need both incomes to afford it | Joint application |
| Your credit has issues and your partner's is strong | Possibly your partner applying alone, if they genuinely want the car and the debt in their name |
Does being in a relationship link our credit files?
No. Australian credit files are individual. You only become linked through joint credit, such as a joint loan or joint account. Checking your own credit report is free, and it's worth both of you doing it before applying.
Be honest on the application
Lenders ask about dependants, shared expenses and your partner's income for good reason. Leaving things out to look better on paper can lead to a loan you can't comfortably afford, and it can be treated as misrepresentation.
