for an uncontested divorce can i file it myself in pa?

You can always file documents in court yourself.  The reason people hire attorneys is to simplify the process.  You will be held accountable to the same rules an attorney is so familiarize yourself with the local rules on service and filing fees.  Most counties offer a divorce packet and you can check with the legal library at the courthouse.  The packet will provide you the necessary forms and paperwork to file with the prothonotary.  Generally, the court charges between 400 and 500 for a divorce.  The process usually takes 3 - 4 months to complete.
