Child Support is calculated based upon each parent’s gross income and on the percentage of time that each child is spent with the other parent among other things.  The formula does not consider the time spent in day care or school as time spent with a parent.   So, if the child is in day care all day or school and then spends 5 nights out of 7nights a week at their grandparent’s home then is the parent receiving the child support payments really supporting the children? or is it the grandparent that is supporting the children?  Why don’t we just rename child support as spousal maintenance and then just call it a day!
