Me and partner have seperated ( I didn't want to) and she wanted me to move out of our home which I didn't want to but moved back to my mothers (only had the house 1yr) we have joint mortgage and 3 children. I work full time, partner works cash in hand so no payslips etc. She is going to be getting universal credits and says she can afford the mortgage. I now pay nothing towards the house as i am not living there. The car is in my name but she has it for school runs etc so,I have told her I am not paying for the car I am not using. We have agreed a few for child maintenance. I want to sell the house so I can use my share of equity to move on, she won't entertain that for at least 6months which I don't want to wait that long. I can't get a mortgage with my name on the joint mortgage, I can't take my name off our mortgage as she has no proof she can afford the payments. I need to know what rights I have. Also child support is based on gross wage not take home. Once I get a new place be rent or mortgage do I deduct the cost incl bills from my wages to work out new child support fee?
