John and Sally were married in 1990. They had two kids, one in 1990 and one in 1996. John and Sally divorce in 2010. Neither asks for child support as they share custody and expenses. John has primary residency.
Two years pass. John remarries and has another baby in 2012. The oldest of John's children is not eligible for support, and the youngest is now living primarily with Sally. So NOW Sally files for child support.
John's state law has a multiple family application that is defensive in nature - meaning if the recipient seeks to increase support or change the order then subsequent children are considered in the amount the payor must pay.
Now what result should happen? For those who insist that first born children should not get "less" due to subsequent children, how do you handle this situation? The law is very clear, obviously. But since presumably you don't like it - how do you think it should be made "right" or "fair" in your opinion?
