Freind has been divorced one year
Lives in Scotland so law slightly different to England
Divorce agreement says he will pay " 1200 a month or csa ,whatever the greater "
However a year later he is struggling and has calculated based on number of nights dc with him over last year he should by csa calculation be paying 800 and another night a month it would be 600'
His XW works and earns well and receives tax credits and child benefits and received entire marital wealth and pension ( he concedes he was rather over generous in his haste to get away from a very unhappy marriage .) her income is actually higher than his .
What can he do to reduce this amount ( he would prefer to pay more directly for his DC e.g move them to private secondary school education , pay for extra tuition or holidays, museum trips which they don't seem to receive with their dm
Can he just reduce or is there a Legal procedure applying directly to court and is it Costly ?
His ex is not the sort of person he could reason or negotiate with .
