One of the most polarizing aspects of a child custody dispute in Arizona might have to do with a grandparent who wants custody of a child. This scenario can be for a multitude of reasons and is happening more frequently than ever. In some circumstances, the parents are not deemed fit to care for the children. In others, there is a personal issue for which the grandparent has to step in and care for the child. Sometimes, the biological parents are amenable to grandparent custody. Grandparents need to understand the facts when they're trying to exercise grandparent visitation or have custody outright.
