Key takeaways
- You are generally only responsible for debts in your own name or ones you took out jointly. Marriage alone does not make you liable for your partner's sole-name credit debts.
- With a joint debt, each of you can be asked to repay the whole amount, not just half. This is called joint and several liability.
- Separation or divorce does not end a joint debt, and an agreement between you and your ex does not bind the lender.
- Household bills such as council tax can be different, because you may be liable if you lived in the property.
- Joint borrowing links your credit files, and this link can continue after a split until it is formally removed.
Money worries often involve more than one person, and one of the most common questions is whether you are responsible for a partner's debts. The answer depends on whose name is on the debt. Debts in your partner's sole name are generally not yours, but debts you took out together can be recovered from either of you in full, even after you split up. This guide explains how joint debts work, what happens if your partner cannot pay or you separate, how your credit file is affected and where to get free help. It covers England and Wales, and the rules can differ in Scotland and Northern Ireland.
What counts as a joint debt
A joint debt is one you took out together, usually under a credit agreement that you both signed. Joint loans, joint overdrafts and joint mortgages are the typical examples. Citizens Advice calls the legal arrangement joint and several liability, and it means each of you has agreed to be responsible for the whole debt, not just a share.
That is the rule that catches people out. If you and your partner borrowed £10,000 together, the lender can ask either of you for the full £10,000. It does not have to split the bill, and it can choose the person it finds easiest to collect from.
Debts in your partner's name only
If a debt is only in your partner's name, you are generally not responsible for it. National Debtline puts it plainly: where a debt is in your husband or wife's sole name, you are not liable to pay it. Experian makes the same point, saying that marriage alone does not make you liable for your partner's debts, and that a person is generally only responsible for their own debts.
There are exceptions. If you act as a guarantor for someone's debt, you can be asked to pay if they do not. And household bills work differently. If you lived in a property while arrears built up, you may be liable for bills such as council tax or energy, even if only your partner's name is on the account. Experian notes that you can be pursued for council tax arrears if you are over 18 and lived in the property when the debt arose.
What lenders can do with a joint debt
Because each of you is liable for the whole amount, a lender can pursue either of you, or both. That can happen even if one of you ran up most of the debt, or even if the other person did not know how much was owed. Lenders do not usually take into account who spent the money.
If your partner is made bankrupt, they stop being liable for the joint debts, but you do not. Citizens Advice says you will still be liable for the full amounts and creditors could pursue you for payment. This is one reason it is worth getting advice early, before problems get worse. If you and your partner are both struggling, see our guide to a joint IVA.
After a separation or divorce
A separation or divorce ends the relationship, but it does not end a joint debt. National Debtline says a divorce only ends the marriage and does not end the financial connection, and that you stay liable for a joint credit debt in the same way as your ex-partner.
Agreements and court orders between you and your ex do not change this for credit debts. National Debtline says a financial order does not change who is liable for a debt. Even if your ex agrees to repay a joint debt, you would still be liable, and the creditor can ask you for repayments as well. Joint household bills, such as council tax and energy, also remain a joint responsibility for the period you lived there together.
How joint debts affect your credit file
Sharing a credit account links your credit reports. Experian says that when you apply for shared credit you become financially associated, and lenders may look at your partner's history when you apply for credit. The link does not itself change your credit score, but poorly managed joint accounts can lower both of your scores.
National Debtline says the financial connection continues even when you are divorced or separated, and that missed payments on a joint account appear on both people's files. You can ask the credit reference agencies to remove the link, known as a notice of disassociation, once you no longer share any financial products. Removing a joint debt from your file is only possible once the account is closed, repaid or one name is removed. See our guide to how credit scores work.
If you did not know about a debt or did not sign
If a debt was taken out in your name without your knowledge, you may be able to dispute it. Citizens Advice says you will need to be able to show that you did not sign the credit agreement. Contact the creditor straight away, put your dispute in writing and get free advice.
What to do if you share debts and cannot keep up
The earlier you act, the more options you have. These steps help whether you are still together or have split up.
- List every debt, and mark which are in your name only, which are your partner's and which are joint.
- Tell creditors early if you cannot keep up payments, and ask them to hold the account while you get advice.
- Look after priority debts first, such as rent or mortgage, council tax and energy. Our guide to priority and non-priority debts explains the difference.
- Get free, independent advice from StepChange, National Debtline or Citizens Advice. See our list of debt helplines.
- Do not take on new borrowing to cover old debts without advice, as it can make things worse.
