I've recently left my partner and have a just turned 18 year old ds and nearly 14 year old dd. We still get child benefit for both children presently as ds is still at college. Dd is staying half the week at mine and half the week at her dad's, except in the holidays when she's predominantly with me. Ex is taking half of the child benefit. My problem with this is 1. Ds isn't even staying there so he's providing nothing for him and my DD is saying she doesn't want to stay there as there's no food (probably meaning snacks), she doesn't shower there as he's not brought a slip mat and he hasn't even brought her a hairbrush which I told him she needed to keep at his. Didnt even get them an Easter egg which is no surprise as it's been down to me for the past 18 years. He also has the cheek to say he'll transfer my half to me, like it's his money. Is he mugging me off?
