Does anyone know if I can challenge child maintanance my ex is paying for our child, 4yo. He is angry man, so trying to punish me for split etc. He is paying minimum 260£ as per gov, he is living at his parents for free. I pay for school clubs because working full time , all expenses like petrol, driving to school and back etc etc he only takes his kid maybe once a week, not even for a night. Can I challenge it? I don't want to waste my money , going courts etc if I can't get anything more that 260£. Any ideas? Anyone in the same situation?
