Minnesota Statutes Lands and Minerals (Ch. 92-94) § 92.29. Land patents

The commissioner of natural resources shall sign and issue in the name of the state and under the seal of the state a patent for the land described in any certificate of sale when the principal and interest specified in the certificate of sale and all delinquent taxes due on the land have been paid. The patent shall be issued to the purchaser named in the certificate of sale, or the purchaser's successor in interest by execution, judicial, mortgage or tax sale, or the assignee, vendee, heir or devisee of the purchaser, as shown by a properly certified abstract of title or other evidence if the purchaser's successor is a person other than the purchaser named in the certificate of sale. If the certificate of sale has become lost or destroyed, an affidavit stating that fact or a certified copy of the certificate must be submitted by the applicant for a patent. When total payment is made within 90 days of the sale, the commissioner shall sign and issue, in the name of the state and under the seal of the state, a patent for the land sold.
