I have been billed half of private schooling fees for two kids by Child Support Agency and the money supposedly goes to my ex for paying half of the private school fees for the children. Based on CSA's assessment, my ex and I should pay 50/50 of the school fees. Child Support Agency charges me the half and my ex is responsible for pay the full fees to the school. The school contacted me lately and advised that the children's school fees are in arrears as my ex is not paying. I have suggested to the school that I have paid my half to my ex via CSA. The school's answer is they do not care of the arrangement between the parents, they just want to recover the fees. I have tried to contact Child Support Agency and they have told me there's nothing they can do. If my ex doesn't pay her half of the school fees or don't even pay any school fees with the money I paid for kids' education, what can I do? (The school is threatening to take legal action on me). My income is much higher than my ex's, but I'm paying maximum child support for two kids plus a decent amount of spousal maintenance for the ex, with other liabilities. The bills all together have put a heavy weight on me. Any suggestions?
