Support obligation of each parent

The monthly support obligation of each parent is automatically calculated by multiplying the total combined child support costs from line 8 by each parent's proportionate share of the combined adjusted monthly gross income from line 4.

COMMENT: A court or administrative agency may, but is not required to, order each parent to pay his or her support obligation (line 9), less any additional child rearing costs paid directly by him or her (line 7), to a third party who is, or has been, awarded physical custody of the children who are subject of this proceeding.
