Absent father is an EU citizen as he moved out of the UK 10 years ago. It's covered under REMO, but I'm not sure where to start. There's no court order in place, the maintenance was calculated by the CSA 12 years ago but it wasn't collected by them, ds's father transferred it to an account for ds every month until May this year, when he stopped paying. It's not been assessed to see if it's the correct amount, he's in a managerial job but now has 2 other children. Do I need to get a court order before I apply for a REMO? 
Thank you.
