My ex feels he is being overcharged for child support by his previous partner. She set the child support on him when he lost his job. Now he has started a new job, they have started to take money directly from his salary, at a level which is significantly higher than he would have expected. They don't seem to take in account that he was out of work for almost a year. He isn't having any luck getting an explanation from them. Would they tell me why? He pays me for 2 children yet she gets double for 1 child.
