’ve been paying CSA for near on 19 years, Only ever missed one payment due to the CSA incorrectly calculating my payments, This was sorted pretty quickly (less than a month) a DEO was set up which was fine, everybody was getting paid, nobody had any issues, Then when the CSA shut my case they suddenly sent me a bill for £12k….with the reason “This is the amount of arrears that you built up under your child support agency case during a period when the parent with care in your case was receiving income support or income based jobseekers. When this happened, we transferrred the money owed to the secretary of state, rather than the parent with care, this was becasue the parent with care was paid benefit during that period”…….I’m abit confused to say the least
