Ex husband threw me and our daughter out of his home

Well were do i start? firstly my ex husband not only threw our daughter out but me also leaving us homeless but he took over my business which meant i was jobless too .After eventually getting a house and job i have now been diagnosed with a health issue which could mean i lose my job. I have taken the decision to use CSA as he has left me in debt and has not made ant contact with our daughter in the last 19 months.

CSA have ruled he has to make no payments as “He is paid in foreign currency”, however he works for a uk company and gets paid in English currency , has a bank account and pays uk taxes so what route can i use.If i go on benefits my daughter will loose out and he will have a whooping £75K per year to live on.This cant be right or fair.
