My wife's ex husband has their 2 children living with him and she has been paying maintenance (not via csa) paying him by cheque every month.In sept 2009 she became a fulltime student however she also works 1 day every weekend with a monthly net income of max £400. Her ex is demanding £120 per month threatening that if he doesn't get it he will contact the benefits office / csa who according to him will take my wages into account.my son from my previous marraige lives with us and my wifes kids stay over every week at least 1 night. My question: is my wife's student bursary taken into account as well as my wages ??
