These research notes look at the differing ways in which the basis for including a criterion regarding children's opinions in disputed custody and visitation processes, in the US as compared with Sweden, impacts on the role and place that children's opinions and wishes will have on the process. Sweden's rationale for including children's contributions to decisions made regarding them has as its underlying basis the idea of a right which arises from a moral obligation toward children as represented in the United Nations Convention on the Rights of the Child. In the US, the inclusion of the criterion which allows for the weighting of children's opinions regarding decisions made about them arises from a legal basis which sorts action into what is acceptable and unacceptable adult behavior toward children. The notes were generated from a larger study comparing Swedish and US custody and visitation disputes between two parents. (Contains 10 notes.)
