Thank you for your question
My name is Clare
I shall do my best to hep you but I need some further information first
How old are the children
Yes of course
How much are the arrears?
Yes it is the form that you can feel in which allows the Court to set the "protected income" rate
You can find it here
The court will then identify what the protected income level should be - and only your earnings above that line are at risk
To actually attack the basis on which the money is being taken you will still have to go through the CSA appeal process.
Please ask if you need further details
