Ok so longish story. Husband and I bought a house 10 years ago in joint names. It was a shared equity property where you have to pay the 25% back after 10 years. The marriage didn’t last and I asked him to leave after 2 years. He did and I stayed in the house with our then toddler. He paid maintenance and I paid the mortgage payments but could only afford the interest only mortgage. I meant to change it to a repayment mortgage but couldn’t afford it so now 10 years later i’ve still only paid the interest. The house is only worth the price of the mortgage and the builders now want their 25% which I don’t have! We haven’t divorced because exH agreed he didn’t want to force me and our child out of the house as the bank wouldn’t agree to take him off the mortgage. 2 years ago my new partner moved in. My ex has been pestering me for years to start paying some capital but I just can’t afford to, even with my new partner living with us. He pays for shopping here and there etc but doesn’t earn much himself. ExH is now getting difficult and saying the house needs sorting. He says he shouldn’t have to pay half the 25% the builders want because he only lived here for 2 years and I haven’t paid anything except the interest even though I said I would (just couldn’t afford to!) but I think he should have to as his name is on the mortgage. He wants to file for divorce now and says if we don’t come to an agreement on the debt it will end up costing a fortune in legal fees which of course I don’t want! Any ideas where I stand here and whether I’m wrong to ask him for half of this money?
Thank you
