Assuming that Allegheny County is the proper jurisdiction, I have pasted below a link to the Allegheny County Family Division Court Manual. Section II-5 of the manual links to a Petition for Modification of a Custody Order. Click on the order, fill in the blanks, and file it with the court at 440 Ross Street in downtown Pittsburgh. Attach a copy of the original custody order. If you believe that your daughter is a flight risk, you may consider filing an Emergency Motion on that basis. Here is a link to the manual:
Go to the Family Courthouse at 440 Ross Street on a Tuesday or Thursday morning at 8 AM sharp, and an attorney or law student will help you complete the paperwork for free.
If money is tight for you, I provide my legal services on a sliding-scale basis according to each client's income. Feel free to call me. 412-389-5502.
Best of luck,
Allegheny County has a pro se assistance program, you can find out more about the program here: http://www.alleghenycourts.us/family/adult/pro_se_assistance.aspx If you do not qualify for the program because of your income, the custody forms are available for you to pick up at the courthouse.
If the case is in one of the surrounding counties you should contact your local courthouse to see if they have a pro se assistance program.
