My son is in a committed relationship with the mother of 3 children from previous marriages. He has no children. They would like to marry; however, 2 of 3 children receive Medicaid for health reasons (1 mental, the other physical). If they married, son's insurance wouldn't nearly cover their medical needs. They want to marry and vow their lives together forever before God though, but not get the state involved. Is there a way to do this?
