My soon to be ex-husband want to take our children off forward health 100% and put them on his insurance through united health care as primary and my forward health from the state as secondary,how do I make sure he will then be incharge of any and every health cost while they are in his care since I do not agree with this change? I'm a stay at home mom of 2,live with my boyfriend who supports myself my 2 kids and himself plus bills... currently I am not getting child support yet still waiting on that. Our placement/custody will be 50/50 joint(every other week)
