There are lots of sites on the Web where you can pay for what, if you knew where to go, would be free. Two links for you: if the matter is pending before, or never proceeded past, the magistrate level go to http://ujsportal.pacourts.us/DocketSheets/MDJ.aspx
If you are interested in seeing what occured/is occurring in Common Pleas Court then this is what you want: http://ujsportal.pacourts.us/docketsheets/cp.aspx
You can obtain Pennsylvania criminal dockets from the Pa UJS web portal: http://ujsportal.pacourts.us/ . These are not the actual dockets kept by the clerk of courts or Magisterial Disrtict Judge's offices. If you want the actual case file contents and documents for court records you do have to pay a copying fee.
