One child graduating in June of 2013, the other in June of 2016. Last modification occurred in November of 2008. Support has always been granished from my wages. I have no desire to modify due to expense and the fact that it is all over in three plus years. However, since it is garnished from my wages, how do I notify the court when my youngest graduates and do I need to present proof ( such as her highschool diploma certification/birth certificates) of both girls’ graduation/age at that time?
