15 Pa.C.S. § 505

Where any corporation governed by this part or created or intended to be created or governed by any statute supplied or repealed by this part has, in good faith, extended its territory or term of existence, changed its name, merged, consolidated or otherwise altered or amended its charter or articles under any statute supplied or repealed by this part but without the actual recording of a document or documents evidencing the corporate action in the office of any recorder of deeds, as provided in such statutes then in force, and a record of the corporate action is on file in the office of the clerk of any court of this Commonwealth or in the Department of State, the corporate action shall nevertheless be deemed and taken to be valid for all purposes, regardless of the omission to record the document or documents as heretofore required by such statutes, and every such corporate action shall be deemed and taken to have been effected upon the filing of the corporate action in the office of the clerk of any court or in the department, or upon the approval of the action, if required, by a court, or by the Governor, Secretary of the Commonwealth or other officer performing corresponding functions with respect to corporate affairs, whichever event has last occurred.
