My ex (not married) left me in a joint home, in a real mess, so bad the house was deemed not safe for 2 kids to live in. and stopped paying half the mortgage and just 16 p/w maintenance for 2 Children.
I met someone new he helped me make the house safe, but still not in a position i could sell it to get away from my ex. I got InTouch with my ex and told him my new partner was willing to help me with the house but wasn't happy to knowing his name was on the mortgage, my agreed he didn't want any of the profits from the sale if my partner want to help me. after 5 years my partner has invested time and money to help me renovate the property my ex now wants half.
