N.D. Cent. Code § 32-19-26: Actual receipt of notice always sufficient

In any case, service of the notice before foreclosure is sufficient if it actually was received by the title owner or by the personal representative of the owner's estate. A United States post-office registry return receipt showing that the envelope containing the notice has been delivered to the record title owner or to the personal representative of the owner's estate, or to the agent of either, is prima facie evidence that the owner or the owner's administrator or executor received the same.
