I have been divorced for 6 years. I pay child maintenance and spouse maintenance under a segal order. No problem with paying child maintenance but the ex is now working and earns £40,000 per annum. When the order was set she was not working. Now she has the extra income what would my chances of succeeding if I take her to court to vary. She is still in the former matrimonial home and we have a mesher order whereby I get my 25% back when youngest is 18.
