i have one dc. her dad gives some money regularly but i don't think it is enough, and every time i ask him to contribute towards something for example sports clubs or school uniform, he gets annoyed and says the maintenance is enough. I don't want to cause hassle, but i was wondering if the child maintenance service can do a check for me without him knowing? To check his wages and how much he should be giving? if it is a lot more, then i would think about going through them, if not then i would just leave it. he won't tell me how much he earns. thanks!
