In traditional relationships, there is such a thing as marital presumption. This presumption means that with children born into a marriage, a legal parent-child relationship is recognized between the children and their mothers’ husbands regardless of the existence of any biological relationship between the two. This same presumption does not exist for children of same-sex marriages.
Beyond denying certain financial and health benefits to children of same-sex marriage, the lack of this presumption could prove disruptive to the child’s family life as well. In traditional marriages, if something were to happen to a child’s biological mother, the father would still be considered a legal parent. That is not the case in same-sex marriages where the non-biological parent has no marital presumption. Adoption is not always the answer either since a number of states fail to recognize adoptions by same-sex spouses.
