The Pennsylvania UCC3AP Financing Statement Amendment Additional Party (National) is a document that is used to add a party to a UCC3AP Financing Statement. This document is used when an additional party is needed to add or release a security interest on the financing statement and is filed with the Pennsylvania Secretary of State. There are two types of Additional Party Amendments: an Additional Debtor Amendment, which adds a debtor to the financing statement, and an Additional Secured Party Amendment, which adds a secured party to the financing statement. Both of these are filed in the National UCC Database.
