Thank you Cookie. Like i said last night, all advice is taken onboard, whether it be what i want/need to know or not.
(oh, i have the misfortune of being married to a cretin who did indeed put himself out of work to avoid child maintenance with his previous ex-wife while we were together. Don''t think she knows to this day he works Tbh. No contact at all)
You wouldn''t be able to go for CSA back payments. The CSA will only deal with payments from application. I do agree with Cookie though if he refuses to give you the additional £150 you are better off going through the CSA. Give him the choice but the ultimately the decision to make a CSA application is yours.
Do not be frightened by his scare tactics he could put himself out of work whether paying the mortgage or the CSA. His attitude to me says he is hiding something. Why is he so keen to avoid the CSA?
