Please could someone give some advice regarding what would happen in the following situation
A and B want to divorce. They have been together 12 years and married for 8 years. They have one child together aged 12. B has an adult child from a previous relationship who has not lived with her since the child was 14. A earns a reasonable salary, works overtime and pays for the mortgage and all of the bills including a car on finance. B has only ever worked a few hours a week since way before they got together. There is little equity in the house, perhaps a few thousand. How would the finances work in this situation? Would A have to maintain B and child in the family house, and still be able to live somewhere else himself, especially as B cannot afford to pay for much in the way of associated bills, let alone any mortgage.
