Who is responsible for paying child support?

Typically, the parent that has the greater income is responsible for paying child support (assuming the party earns significantly more income than the custodial parent), while the custodial parent receives the support on behalf of the child. There are instances where the custodial parent makes significantly more income than the other parent, and in those situations, the custodial parent may have to (depending on the custody time share) pay child support to the other parent.
