I am in a very difficult situation with my ex partner, please excuse the long post. We have three boys. We separated in 2015, having bought a home together in 2003, and our second home in 2008. We have a joint mortgage. He refused to leave the family home and our relationship was awful, so after two years of living separately under the same roof I left and was rehoused by the council. Kids were then 8, 6. and 4. He has never compensated me for my share in the house, or paid any child support. He has taken the boys every Saturday-Sunday (about 24 hours) each week and more in holiday time etc.
Recently he has met someone else and he has dropped out of our weekend arrangement. He sometimes takes the children on a Sunday afternoon. He cuts off my calls when I ring at the weekend and ignores texts. Looking after the kids overnight would interfere with his sex life I guess. I have not heard from him for three weeks.
I still retain keys to our home, and frankly I am not very happy where I am now - it's quite a dodgy estate and I don't much relish the thought of bringing my sons up there, now they are getting older. My eldest has additional needs and is quite vulnerable. The house is very small compared to the house I left. My name is still on the mortgage and title of the old house.
I am very angry with my ex, I will admit that, and this may be driven by absolute rage - I find his behaviour reprehensible and I have nothing but contempt for him. I would very much like my home back (if he is not going to provide any overnight care for the kids, why does he need it?) but aware that the legal battle will be costly. Am I entitled to take my house back and eject him, given how unreasonably he has behaved? He has paid the mortgage for the past 7 years, but previously I paid it, and he owes a fortune in unpaid maintenance. Legally does he have any right to remain in the family home? I really do need proper legal advice on this, but any thoughts would be welcome.
