Divorced in 2022, 3 kids all with SEN, fully diagnosed, EHCP etc. Eldest was flunking in y10 and his school also does weekly boarding so he suggested boarding for y11. His father tried to block it because he didn’t agree with private education - except it’s not private, it’s state - and said he wouldn’t pay the boarding fees so I’m paying them myself. Son absolutely loves it, is thriving and his grades have rocketed. He wants to stay in for 6th form and ex has said that he won’t try and block it but in no way should he be liable for the cost. So I’m covering it all. Is there anything I can do other than just suck it up and pay? He earns three times what I do, and hardly sees the kids anyway. He pays CMS at CMS rates (which he keeps artificially low by taking his bonus as shares) and we have nominal spousal maintenance. He’s also an arse.
