ND is pretty liberal about recording documents. Whether you record an affidavit of nonpayment or a declaration of lease forfeiture for nonpayment they should record it either way. A simple phone call to the county recorder’s office you are going to record it in would probably provide the document title they would prefer. I think they are nonjudgmental as long as you leave them enough space in the margin for their barcode and enough space for the seal. Of course you need the legal mineral descriptions so they can index it properly.
