Going through a separation or divorce can be stressful and often means your financial situation is affected.
Any joint debts you have with your partner will have 'joint and several liability'. This means that, if your partner cant make payment to the debt, you will need to repay the full amount.
If you dont have any joint debts you can get a notice of disassociation. This removes any financial link with your ex-partner on your credit file. To do this you need to contact one of the credit reference agencies who can remove this link.
