I am not sure if this would work for you, but if you get health insurance through your company you can check to see if they participate in the Domestic Partner Program, even though you are married and are not domestic partner ***** you may be able to get the son on your insurance. Some companies participate and some don't so it is through your HR you would need to check. As far as the dead beat Dad not providing court ordered support you may want to consider legally changing the boys name to yours and that way he is legally your son without going through and entire adoption process, my stepdad did that to us when we were kids. I don't know what state you live in but you can check into what we have here like healthy NY or Family/Child Health Plus that is Government funded, it is fully comprehensive and very inexpensive. Good Luck with the insurance and I hope your step son has good health in his future
