One of my new clients just came to me to file a motion to increase child support as the number has not been adjusted in over a decade.  As a result, she has been missing out on thousands of dollars per year as the number is off by anywhere from 50% to 75%.  In addition, she never sought any contribution for medical expenses which is even more money that she has left on the table.  Lucky, we may be able to get some of that back.  But since there is no retroactive child support increase, she will still lose a ton of money.  Moral of the story:  act now!
