Among the individuals affected by divorce are the parents of the divorcing persons. Their role must be seen through three perspectives: that of the older persons themselves, that of the divorcing couple, and that of the children of the divorcing couple. A dozen grandparent-of-divorce settings are outlined and their implications discussed. Significant variables include which parent has custody, subsequent remarriage and the new grandparental relationships that are established, and the perceptions of the grandchildren of their new family relationships.
