It depends on the state you live in and the age of the child.
In general, child support is paid by absent parents.
If you do not live with the child or directly support them you do.
if the child is special needs and has to live with a parent yes otherwise no
If you have an order, you must pay child support.
It is based on where the cs order has been filed. Child Support orders should be filed in the state where the child lives with the custodial parent.
In general, child support obligations are imposed on absent parents.
when a person has a child it is mandatory that they pay child support no matter where they live

You have to pay child support for any of your children that does not live with you. So if you have 3 kids that live with you and one kid that lives with your ex you would be responsible for paying child support for the one child that lives with your ex. However, you only have to pay, legally, when a court has ordered you to. If your ex is paying child support for the three kids that live with you a court could order a reduction in child support that he/she has to pay to you instead of you having to pay child support to him/her.
