can anyone offer any advice. My partner and his ex are currently divorcing they have 2 children the youngest is 11. My partner is paying child maintenance and half the mortgage on the FMH where is estranged wife lives with the children. His ex says she can no longer afford to pay her half of the mortgage but says that she cannot be forced to sell the house until the youngest child reaches 16, she has told my partner that they must jointly remortgage to reduce the monthly payments, i don't believe she can force him to do this, i believe she has run up debts herself that she wishes to pay off in the remortgage as she no longer afford to pay them
