Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
Is he able to ocntact his ex at all?
If they were able to speak then they could both agree to setting one debt off against the other - the CSA will not do it but with a joint approach it would be possible.
As things stand all your son can do is offer instalment payments if the money is actually due.
One option would be to offer £100 a month from October - then the money that he receives via the CSA can go straight back there.
Not ideal I know but sadly the best that can be done
Please ask if you need further details
