My partner has just admitted to being in 5k in debt. It was not spent on the house or towards household bills just purely on himself and has acquired 3 ccj?s on joint Water and gas bills (the only bills he pays out of his account) so that means I now have 3 ccj?s on my file. I have agreed to get 5k on the mortgage but would like something drawing up by a solicitor to say if we split up he will have to pay that 5k back to me, does this sound fair?
