A joint credit card is one of the most immediate financial risks after separation. Unlike a joint savings account, it carries ongoing liability: if your ex-spouse keeps using the card after you split, you're still on the hook for the debt. Australian banks don't release one party from a joint credit card simply because a relationship has ended. You need to act, and act quickly.
Understanding joint liability on a credit card
When two people open a joint credit card, both names appear as primary cardholders. The bank treats each holder as fully liable for the entire balance, not just half. This means a creditor can pursue either of you for the full debt regardless of who made the purchases. Separation doesn't change that arrangement in the eyes of the bank.
It's worth distinguishing a joint card from a supplementary card. A supplementary cardholder is an additional user on the primary holder's account. The primary holder carries the legal obligation. If you're the primary holder and your spouse was a supplementary user, removing them is simpler. If the account is genuinely joint, closing or converting it requires both parties to engage with the lender.
Your first steps after separation
The priority is stopping new debt from accumulating before you've worked out the financial split. Take these steps as soon as possible after separation.
- Contact the bank immediately. Notify your lender that you've separated and request a freeze on new purchases, or ask for the supplementary card to be cancelled if your spouse was only an additional user.
- Request a transaction statement. Get a full statement covering at least the past 6 months so you have a clear picture of the balance and who made which purchases.
- Pay down or clear the balance. Most banks won't close a joint account while a balance remains. If you can pay the card to zero, you remove the risk of ongoing interest and simplify the closing process.
- Do not close the account unilaterally without advice. In some circumstances, closing a joint credit card prematurely can affect both parties' credit files and complicate a formal property settlement.
How to handle the existing balance
This is where it gets complicated. The balance on the card at separation is a shared liability, but who actually owes what depends on the circumstances. If the debt was run up jointly during the relationship for household expenses, it's likely to be treated as a shared liability in any property settlement. If one party ran up significant personal charges after separation, a family law court may take that into account.
Rockwell Family Law Services recommends documenting the balance at the date of separation clearly, ideally with a bank statement dated that day or as close to it as possible. This becomes useful evidence if the split of liabilities is later disputed.
On the question of how to split debts fairly when separating, the general principle under Australian family law is that liabilities form part of the asset pool alongside assets. The court looks at the total picture rather than assigning specific debts to specific people.
Options for resolving the joint credit card
There are three practical paths depending on your situation.
Pay it off and close it. If the balance is manageable, the cleanest option is for both parties to agree on who pays it down, clear the balance, and then contact the bank to close the account. Get written confirmation from the bank that the account is closed and the liability discharged.
Transfer the balance to one person. One party can apply for a new individual credit card and transfer the joint balance to it, effectively taking on sole responsibility for that debt. The joint account is then cleared and closed. The bank will run a credit check on the individual applying for the transfer, so this depends on that person's standalone credit profile.
Refinance into a personal loan. If the balance is large, converting it to a personal loan in one party's name can freeze the interest rate and give a clear repayment schedule. This removes the revolving credit risk of a card and gives both parties certainty.

What to do if your ex-spouse won't cooperate
This is a real and common problem. Banks generally require both account holders to consent to account changes on a joint credit card. If your ex won't engage, your options narrow but don't disappear.
First, contact the bank and explain the situation. Ask specifically whether they offer a unilateral hardship or separation process. Some lenders have internal policies for separated couples that allow one party to freeze the account pending resolution. It's not a legal right, but it's worth asking.
Second, seek legal advice. A family lawyer can send a formal letter to your ex-spouse outlining that any new charges incurred after separation may be treated as their sole liability in proceedings. This doesn't bind the bank, but it can change behaviour. It also creates a paper trail if the matter goes to court.
Third, if your ex-spouse continues to use the card and the debt is growing, you may need to apply to the Federal Circuit and Family Court of Australia for interim orders to protect your financial position.
The effect on your credit file
A joint credit card appears on both parties' credit files. If the account falls into arrears, both credit scores take a hit regardless of who stopped making payments. This is why protecting your credit during separation isn't just about your own accounts. Joint accounts you might have forgotten about can still damage your financial standing.
Check your credit report through Equifax Australia or another licensed credit reporting body after separation to see every account listed in your name. You may find joint accounts you weren't fully aware of, particularly if your spouse managed the household finances.
How the credit card debt fits into a property settlement
Any joint credit card balance at the date of separation is typically included in the liability pool during a property settlement. It reduces the net asset pool available for division. If one party has already paid down the joint card using their own funds after separation, they may be entitled to a credit for that contribution in the final settlement figures.
Keep all receipts and bank records showing who paid the balance and when. These records matter in negotiations and, if necessary, in court. Your family lawyer will use them to argue for an adjustment in your favour.
