"Payment under a maintenance order or Child Support Agency assessment" are considered as reasonable expenses. In my situation my monthly payments to the mother of my child are not formal with regards any Orders and don't involve the CSA but I do have records going back quite a while of monthly standing order's being made to the mother of my son. I'm not on his birth certificate and we were not married, do you think the OR will query this?
Maybe I could take my boy for a day out at the High Court? Or the OR can interview him, he's definitly my son
