Who Is Going To Fight For My Daughters Rights

My daughter is 15 years old. I originally filed for child support in 1997. I have helped the absent parent by waiving/excusing child support arrears so that he could better himself.

I filed for a Request for Modification in August of 2009. Neither the absent parent nor myself live in the state the order was originated. When I originally filed my request the caseworker told me that I could file the case in the original state or the state I or the absent parent lived in. I requested to continue the case in the original state because it has been there all this time. The case was continued by the caseworker and the supervisor reviewed and sent the documents to the attorney. Here it is a year later and the attorney says that request cannot be completed because neither parent lives in that jurisdiction. The problem I am having is that, that is the only jurisdiction I've every filed my claim with. I have not lived in that state for about 10 years and the absent parent over 5 years. I don't understand how they can process my request and then at the end tell me that they cannot continue because we no longer live in that jurisdiction. How can this happen?

I don't know what to do. Why should my daughter have to suffer because they made a mistake? Is it my job to know their job? If this had been told in the beginning I would be more understanding but to basically approve the request and then a year later deny it, how can this happen?
