Ohio law dictates that the biological parent of a child, an adoptive parent or a parent who has acknowledged paternity on the birth certificate of a child has to pay child support, according to DivorceNet. This is addition to Ohio law's mandated parent duty of support on married people.
Ohio law states that there is an obligation to continue child support until the child reaches the age of 18 or become emancipated, says DivorceNet. A parent may also have a duty to pay child support beyond the age of 18 if the child has a mental or physical disability and cannot support himself.
When courts are ordering or modifying support, they must use a specific worksheet established by the Ohio Supreme Court. The guidelines are assumed to be the correct amount paid unless the court finds that the amount is unjust, is not appropriate or is not in the best interest of the child, explains DivorceNet.
Ohio law allows support to be modified if there is a material change of circumstances with either the parent or the child. The court must decide if that change actually exists and how to determine the new amount of support to be ordered, states DivorceNet.
