In Virginia, child support is calculated based upon statutory guidelines. There is a presumption that the support figure calculated utilizing the guidelines is correct. However, if a judge deems it appropriate, and upon consideration of a list of specific statutory factors, a deviation from the guidelines may be ordered. In some cases, taking into account the child's needs and other financial settlement arrangements, the parties may elect to set a support figure that they feel is appropriate, pending a judge's approval. Childcare costs, health insurance costs and the amount of time the child will spend with each party is taken into account in the guideline calculations, as well as in any deviation. Child support continues until the child turns 18, is emancipated or, if still attending high school and residing with a parent, when he or she turns 19. Additionally, a parent may contract to support a child who is over the age of 18 or not a full time high school student in special circumstances.
