Me and my ex bought the house in 2008. I had 2 boys with him and a daughter from a previous. We got our deposit from keyworkers he was a policeman and I paid all solicitors fees and furniture for the house. In 2013 he lost his job in the police and due to lies we split. I stayed in house with my 3 children taking over all bills. He didn't pay maintenance until 2 years ago. This is still not frequent. My new partner and I would like to buy a house together and need to sell my property. My ex has stated he wants half the house. Is this correct? When we split he took out a loan in both our names without my consent and has failed to pay this for the past 4 years and I know have a charge over the property. Can anyone please advise if 50/50 is correct. Thank you
