The basic rule
Whose name is on the agreement decides who’s liable:
- A debt in your sole name — only you are liable.
- A debt in your partner’s sole name — only they are liable. You are not, even if you’re married, in a civil partnership or living together.
- A joint debt — you’re both liable, and under “joint and several liability” each of you can be chased for the whole amount.
Being a couple does not merge your debts. Marriage doesn’t make you responsible for your spouse’s individual credit cards, loans or overdrafts.
