NRP hiding income from CSA

I must have been lucky my ex is self-employed and did give the correct figures to the csa. But would only agree to pay it if it was payed direct to my daughter. Which I agreed to. But he is now appealing as he says he looks after our daughter as much as I do.

He has only seen her four times since November and only then when he was asked to.

My ex is currently being investigated by CSA criminal compliance...and it's a long slow process...I'm not getting call backs as promised and he's laughing in my face and about to fly off on (another) holiday...I live in the hope that one day they'll nab him and I can take the kids away.
I mean, seriously, how can someone earing £104 get a mortgage for a 6 bed exec house????...come on CSA pull your finger out!...PLEASE!!

My ex had a CSA Committal Hearing just over a week ago (has paid nothing for the 4 children in over 7 years). Criminal Compliance got involved 18 months ago, they got a Liability Order for the arrears a year ago.
He's self-employed and told the CSA he was earning £4,500 pa but the Tax Office said he was declaring £9,500 so this has been the figure used by the CSA to vary the assessment.
With self emp NRP's, the CSA have an uphill struggle, as do the RP's trying to cope.
