Child Support stems from the legal right of every child to be taken care of and provided for by the very persons that brought them into this world. It is a right that belongs to the child and the child alone. This right does not belong to either of the parents to disregard or waive even if they wanted to. Tennessee uses the income shares model to determine what child support should be ordered in each specific case. Child support is determined by factors that include the income of both parents, the number of days a child spends with each parent, and the expenses paid by each parent for the child which includes child care, health care, and extracurricular activities.
