How is child maintenance affected by cash benefits and company cars ?

Dont go through the CSA. They are useless. They dont need to know anything they are only there to advise. I settled outside of them with my ex. Explain to your wife the amount you take home after tax, car etc and deduct from that, thats if you are on amicable terms. Its 15% of your earnings after tax you need to give, but if this an issue, than talk to your ex. �700 quid is too high if you ask me.
