The amount of child support depends on a variety of factors which are set forth in child support guidelines within the Ohio Revised Code. Child support is determined using a formula taking into consideration the number of children you have, the income of the parties, the parenting arrangement, medical care costs, daycare costs, who receives the tax dependency exemption(s) and various other factors. Therefore, the amount of child support can vary considerably. Deviations from the child support guidelines are allowed under certain circumstances. In most cases, child support is paid until the child turns 18, unless the child is still in high school, in which case child support terminates at age 19. Children with certain disabilities may receive child support past their 19th birthday.
