The term “custody” is often confused with the amount of time a parent spends with a child. Parents can have joint custody of child with only one parent having possession of the child most of the time. Likewise, a parent can have sole custody of a child and have possession of the child for the same amount of time as the other parent. In Illinois, legal custody concerns decision-making power. Who is going to make the major decisions in the child’s life: one parent alone or both parents together?
