A record owner's attempt to tender payment to the county treasurer for all taxes due upon the property complied with this section's requiring that all such taxes be "paid" by a person seeking to challenge a tax deed and gave the record owner standing to assert a claim seeking to set aside the tax deed, though the record owner's attempted tender took place outside of the statutory redemption period; the record owner attempted tender within the redemption period set forth in a public notice by the holder of the tax deed, and the treasurer refused to accept the tender because the tax deed had already issued. Adair Holdings v. Johnson, 304 Neb. 720, 936 N.W.2d 517 (2020).
