My ex and I have been discussing a possible future arrangement where we take care of the kids (DS10 and DS4) one week on, one week off, I.e. a 50/50 split in childcare. Currently they are with me 4 nights and my ex 3 nights every week. He pays £200 a month in maintenance for our two sons and I pay for clothes, shoes, uniform, school dinners, school trips, and most after school activities. I receive about £660 in child tax credit/working tax credit. My ex says he should be entitled to half of all my benefits if we do an equal share of childcare. I have got used to receiving this income and I am reluctant to share it out especially when I pay for most of the kids' things. Who do you think is right here? Thanks
