Joint Debt After Divorce in Australia: Who Pays What?

A court order can divide debts between you and your ex-spouse — but here's what many people don't understand until it's too late: the court order binds the two of you, not the bank. If your ex was ordered to pay the joint credit card balance and they default, the bank can and will pursue you for the full amount. Joint and several liability means the lender doesn't care about your family court arrangements.

How Joint Liability Works

When you sign a joint loan or credit card agreement, you each agree to be liable for the entire debt — not just your half. This is "joint and several" liability, and it survives divorce.

A Family Court order or Consent Orders can specify which party is responsible for each debt. This creates a legally enforceable obligation between the two of you. But the lender is not a party to those orders. If your ex defaults on a debt they were ordered to pay, the bank comes after both account holders. Your remedy is to pursue your ex-spouse for breach of the court order — a separate legal action that costs time and money.

Credit Cards: The Highest-Risk Category

Joint credit cards and secondary cardholder arrangements are the most dangerous post-divorce debt exposure:

• Joint credit cards: both cardholders are liable for the full balance. Either party can continue charging until the card is cancelled
• Secondary cardholder: the primary cardholder is liable for all charges, but the secondary cardholder has spending authority. Cancel the secondary card immediately upon separation

The safest approach is to:

1. Freeze the account — contact the card issuer and request no further transactions
2. Pay the balance in full using settlement proceeds if possible
3. Cancel the card entirely — not just remove one party
4. Get a zero-balance statement as written proof the account is closed

If the balance can't be paid in full immediately, transfer the debt to individual cards or personal loans in the name of whoever the court order assigns the debt to.

Mortgage and Home Loan Debt

If one party is keeping the family home, the mortgage needs to be refinanced into their sole name. Until that happens, both parties remain on the loan — and both remain liable.

The risks during the transition:

• The remaining party could miss payments, damaging both credit scores
• The outgoing party can't easily get a new mortgage while still on the old one (existing liability counts against borrowing capacity)
• Redraw facilities remain accessible to both parties unless explicitly frozen

Request the lender to convert any redraw facility to dual-authorisation while the refinance is being arranged.

Personal Loans, Car Loans, and Buy Now Pay Later

Joint personal loans follow the same joint-and-several rules as credit cards. The loan must be refinanced into one name or paid off.

Car loans in joint names: if one party is keeping the car, the loan should be refinanced into their name alone. If the car is registered in both names, update the registration through your state transport authority once the loan transfer is complete.

Buy Now Pay Later services (Afterpay, Zip Pay): these are typically in one person's name, but if linked to a joint bank account or shared credit card, they can create unexpected charges. Unlink shared payment methods.

Protecting Yourself During the Settlement Period

Between separation and the final property settlement, both parties are still exposed to joint debt risk. Take these steps immediately:

• Notify all joint lenders of the separation in writing
• Request account freezes or dual-signatory requirements
• Monitor your credit report — a free check through Equifax or Illion will show all accounts in your name, including ones you may have forgotten
• Document everything — if your ex adds to joint debt after separation, the court may consider this when dividing assets

Tax Implications of Debt Division

Debt assumed as part of a property settlement is not tax-deductible simply because you took it on during divorce. The deductibility depends on what the debt relates to:

• A mortgage on a rental property remains deductible against rental income
• A mortgage on your main residence is not deductible
• Credit card debt is generally not deductible regardless of how it was incurred

The NSW After-Divorce Checklist includes a debt tracking worksheet that lists every joint obligation, tracks which party is responsible under the orders, monitors payment status, and flags when accounts need to be formally closed or refinanced.
