Is it illegal for my parents to take me off their health insurance if I'm living with them....?

I'm 18 and a sophomore in college. I moved in with my mother and step-father a year ago and he still refuses to put me on his health insurance. My current health insurance expires when I turn 19 and I can't afford to buy my own or to buy my school's health insurance. Is it illegal for my step father to refuse to put me on his health insurance if I am a full time student and passing all of my courses?

He can keep you in his insurance as long as you are in college.Offer to pay your portion of his health cost premium if he is that gosh darn cheap.And no, it's not illegal for a parent to remove a child from insurance./

No. If your mother and father are divorced and the divorce court judge ordered your mother to provide health insurance until a certain age, then she is bound by that. If there is no court order or your father died while married to your mother, then she is not required to provide you with anything after you turn 18. Either way, your stepfather is not required to provide you with anything, at any age. This includes a place to live. They do not have to let you live with them. This raises another point. Since you are 18, you could live alone and might qualify for medicaid as a person living alone with no money or job. However, if you cannot afford health insurance, then you also cannot afford a place to live alone. So forget that idea.

It is perfectly legal. They are not required to provide your insurance coverage.
