Currently dds dad is paying £31.99 a week (£11 being towards his £1000 arrears) so it would be something like £21 if he had no arrears. I got my annual review at the end of march and it said his weekly income was £191 approx. Things he has said has got me questioning how much he really earns for example buying a new bumper for his car (could have saved up but he is not the type of person to do this) he recently slipped up and told me he worked 6 days a week and that he finished at 6pm (he was asking if he could pop in and see dd, i said no because he is covered in crap and oil) am i unreasonable in thinking £191 for 6 days work is ridiculous? When i calculated it all out (minimum wage is £6.70 for his age) he works roughly 10 hours a day, 6 days a week so he really should be getting £402 before tax. So using the csa calculator online we should be getting £48 a week not including arrears. Would it be unreasonable to ask him to be honest and to ask if the csa could do a recalculation with the new information from hmrc?
