When you create a family, you can choose either free or premium emblems to represent your family. Once chosen, a family’s emblem can be changed by a leader by going into the Info section of the Families Lobby and selecting "Edit Details". Emblems belong to the family that purchases them. If you purchase premium emblems for your family then leave the family, those emblems will remain with your old family.
