Child support is just a computer program. You put the data in and it tells you what the number is. It goes by how much you make and how much time you have the child for overnight visits.
One thing that affects child support is, let’s say, father sees the kid three days a week but he is only seeing him from after school until 8:00 at night. That won’t affect the child support formula in his favor at all because that’s not an overnight visit. In most situations you might have a parent that sees the children very often and they’re very involved.
If they don’t have that many overnights visits, the formula somewhat works against them. There’s not much that you can do about it unless you can negotiate some relief based upon your particular circumstances.
