Firstly, Sorry if this has been posted in the wrong area, New to this. Can anybody confirm that the CSA can only take into account your NET pay and not any Specialist Pay you receive? My last calculation did not take these into account but I have spoken to others who have said that their SP has been included? When I made initial contact with the CSA they said it didn't. But we all know what these places can be like, one person says one thing and then when you phone back the next person says different. If anyone knows of a link on the old tinternet that lays down the rules on what is taken into account I would greatly appreciate it.
