The U.S. Court of Appeals for the Ninth Circuit has held that a bankruptcy trustee could not avoid an unauthorized sale of real estate to a bona fide purchaser— although the proceeds of the sale did belong to the estate.

The court ruled that an unauthorized postpetition transfer of real property in California could be avoided only if the buyer had actual knowledge of a bankruptcy filing, or if the trustee recorded the transfer of title to the property from the debtor to the estate in the land records of the applicable county, In re Tippett, 542 F.3d 684 (9th Cir. 2008).
