Rapper 50 Cent is back in court for a child support modification hearing. He currently pays approximately $25,000.00 per month to the mother of his ten year old son. Perhaps you are wondering what 10 year old needs that kind of money to meet his expenses. Child support is determined based on the incomes of the parents of the child. This is due to the presumption that parents who earn more, then spend more on their children. The use of child support guidelines sets up the presumption for the correct amount of child support. This number takes into account not only direct costs such as food, clothing and daycare costs, but also the fact that the parent has higher housing and transportation costs than a single person would. Both parents are obligated to support their child, regardless of whether they have custody or are having visitation.
