Dear KTM:
In a "normal" contested divorce, one side files a petition with supporting documents and, based on those documents, the Court enters a "Temporary Order" setting out the initial conditions of the separation such as visitation, spousal and child support, access to the former family home, etc. These documents are delivered to the other side who can then file a motion to modify the Temporary Order and produce their own documents. Usually there is a brief non-evidentiary hearing on the record and the Judge announces the results often with the comment that his or her order is meant to be "temporary" until the matter is settled or a further hearing. For example, the spousal and child support might be set during the December 15, 2012 hearing based on the higher income noncustodial parent's 2012 wage income year to date plus the annual Christmas bonus of 25% of that parent's annual salary sent out on December 25, 2012. Lo and behold, no December 25, 2012 bonus.
But going to Court is expensive and didn't the Judge say that this is all temporary so why not wait about 6 months until the full trial takes place. The Brown case might mean (remember that it is a new decision) that the Trial Judge can't go back in time in June of 2013 to change the child support Temporary Order of December 15, 2012 even though the evidence in the June 2013 trial clearly shows that no one got bonuses due to the company's financial conditions.
Being an attorney that sometimes has represented this higher income noncustodial parent, I can think several strategies but I would much rather be representing the lower income custodial parent in the June 2013 hearing. "TEMPORARY" CHILD SUPPORT ORDERS ARE NOT AS "TEMPORARY" AS YOU MIGHT THINK. Quite frankly they should be labeled: PRELIMINARY ORDERS (WITH NO POSSIBILITY OF CHANGING CHILD SUPPORT).
Good luck,
Dennis
