Does anyone share residence of their kids with an ex? I have 3 with my ex-d. When we divorced we agreed 'amicably' (but no court order) to share residence ie have them half each. As we (then) earned a similar amount we agreed to share costs too. Now I have a new baby and a new partner and ex is being an arse. Sometimes he only has them 8pm to 8am (ie when they are asleep) and when I complain he says he wants half my child benefit and half the tax credit (which is now nothing due to overpayment). I have now contacted the CSA to try and get him to pay something/anything formally and regualarly.
