Traditionally, Alberta child custody arrangements were classified as Joint custody, where both parents make decisions about the children together. Shared custody where parents split time with the children equally. Split custody where some children live mostly with one parent and other children live mostly with the other parent. Sole custody where the children live primarily with one parent who has a right to make all major decisions regarding the child. However, recent changes to national and provincial divorce laws have changed the language used to describe Alberta child custody arrangements.
