Public Record Search Tip... About Recorded Documents in Pennsylvania There are 67 counties, 67 recording offices and 134 UCC filing offices. Each county has two different recording offices. One is the Prothonotary - Pennsylvania’s term for "clerk" - who accepted UCC and tax lien filings until July 1, 2001. The other is the Recorder of Deeds who maintains real estate records. All federal and state tax liens on personal property and on real property are filed with the Prothonotary. Usually, tax liens on personal property are filed in the judgment index of the Prothonotary.
