Child support may be ordered to be paid by one parent to another when one is a non-custodial parent and the other is a custodial parent. Similarly, child support may also be ordered to be paid by one parent to another when both parents are custodial parents (joint or shared custody) and they share the child-raising responsibilities. In some cases, a parent with sole custody of his or her children may even be ordered to pay child support to the non-custodial parent to support the children while they are in the care of that parent.
