(E) Unless the parcel previously was redeemed pursuant to section
5721.25 or
5721.38 of the Revised Code, upon the filing of the entry of confirmation of sale, or an order to transfer the parcel under sections
323.65 to
323.79 of the Revised Code, the title to the parcel is incontestable in the purchaser and is free and clear of all liens and encumbrances, except a federal tax lien, notice of which lien is properly filed in accordance with section
317.09 of the Revised Code prior to the date that a foreclosure proceeding is instituted pursuant to section
5721.37 of the Revised Code, and which lien was foreclosed in accordance with
28 U.S.C.A. 2410(c), and except for the easements and covenants of record running with the land or lots that were created prior to the time the taxes or installments of assessments, for the nonpayment of which a tax certificate was issued and the parcel sold at foreclosure, became due and payable.
The title shall not be invalid because of any irregularity, informality, or omission of any proceedings under this chapter or in any processes of taxation, if such irregularity, informality, or omission does not abrogate the provision for notice to holders of title, lien, or mortgage to, or other interests in, such foreclosed parcels, as prescribed in this chapter.
