Joint Debt and Credit Cards After Divorce in the UK

A divorce order does not split your debts. Even if your Consent Order says your ex-spouse should pay half the overdraft, the bank does not care. Joint and several liability means the bank can pursue either of you for 100% of the debt — and they will chase whoever is easier to collect from.

Here is how joint debt actually works after divorce and what you can do about it.

Joint and Several Liability Explained

When two people take out a joint debt — a joint bank overdraft, a joint personal loan, or a joint mortgage — both become fully liable for the entire amount. Not 50% each. The full 100%.

If your ex-spouse stops paying their "half," the creditor can demand the full balance from you. If you refuse, they can pursue legal action, register a County Court Judgment against you, and damage your credit record. Your Consent Order is a private agreement between you and your ex-spouse — the bank is not a party to it.

This means that dividing debts in a financial settlement only determines who should pay. It does not determine who the bank can chase. The only way to end your joint liability is to close or restructure the debt.

Credit Cards: There Is No Such Thing as a Joint Credit Card

This is a point of confusion. In the UK, credit cards are always held by a single primary cardholder. A second card issued to a spouse is an "additional cardholder" or "authorised user" — not a joint account holder.

The primary cardholder is 100% liable for all spending on the account, including everything the additional cardholder spent. The additional cardholder has zero liability to the credit card company.

What to Do

If you are the primary cardholder:

1. Contact the card issuer immediately
2. Request cancellation of the additional card
3. Remove your ex-spouse as an authorised user
4. Pay down or transfer the balance — it is entirely your debt

If you are the additional cardholder:

1. Stop using the card — any spending increases the primary holder's debt
2. Request removal as an authorised user
3. Understand that you have no legal obligation to pay the balance, even if you made the purchases (though your Consent Order may require you to contribute)

Joint Loans and Overdrafts

Joint personal loans cannot be split. They must either be:

• Paid off in full using savings, asset sale proceeds, or other funds from the settlement
• Refinanced into one name — the person keeping the debt applies to the lender for a sole-name loan to replace the joint one. The lender will run a fresh credit check and affordability assessment.

Until the joint loan is paid off or refinanced, both parties remain liable. If one party defaults, it damages both credit records.

Joint Mortgage

The joint mortgage is usually the largest joint debt. Even if one spouse has moved out, both remain fully liable for every payment. A missed payment damages both credit records.

Three routes to resolve it:

1. Sell the property and use proceeds to clear the mortgage
2. Transfer of Equity — one spouse takes sole ownership and refinances the mortgage into their name alone
3. Mesher Order — defer the sale until a trigger event (children turning 18, for example), with both names remaining on the mortgage

Protecting Your Credit Record

Contact the credit reference agencies (Experian, Equifax, TransUnion) and file a "Notice of Disassociation" once joint debts are closed or restructured. This breaks the financial link between your credit file and your ex-spouse's, preventing their future financial behaviour from affecting your credit score.

The Wales Post-Divorce Checklist includes a joint debt tracker covering every type of shared liability — bank accounts, credit cards, overdrafts, loans, and mortgages — with step-by-step instructions for closing or restructuring each one.
