Me and my ex share our child equally, half the time each. He pays for some things, like our child’s weekly swimming sessions, I pay for others, like dinner money. So this part is equal but I would say I do most of the organising for things. Example, I will organise our child’s school trips like filling in the forms and he will give me half the money. This has worked but recently I have got fed up of having to message him asking for half of the money for things all the time, so I put in an application for child maintenance. I didn’t realise this at the time but he is on a very large salary and the money it says he owes is hundreds a month, way more than when he was just paying half of things. He is saying he is going to argue this with them as we share our child equally, and according to him, in these sorts of equal cases he doesn’t need to pay any maintenance. He said he will take it to court if he has to. He’s also said I might have to pay any money back if the child maintenance service agrees with him.
AIBU to expect him to pay the maintenance and is he correct in that he won’t need to pay any maintenance in our situation?
