Hello - the response below is correct, but I will take it a little further. I work for the State Judicial System and have for the past 7 yrs in domestic law. As a basic understanding (without me giving you legal advise) child support is modifiable when you can show a 10% change in the original amount - so say the original amount was $200 - the moving party would only have to show that either party's financial circumstances had changed or parenting time had changed to warrant a $20 change in child support (up or down). The most important thing in this case is to file a response to the motion so that the Court knows that you are objecting to the increase - that way they can't do it without your imput and/or a court hearing. You can go to the following website http://www.courts.state.co.us/chs/court/forms/domestic/al... to get forms and instructions on how to proceed with this case. I would also suggest that you contact the Child Support Enforcement Unit up in Jeff Co. for further instruction. If you are getting nowhere at that end and the process is too confusing/frustrating then I would suggeset you get an attorney or contact the Colorado Legal Service office for their class offerings or free legal advise night (3rd thursday of the month from 7-9pm - sorry can't remember the number). Good luck!
