Section 9G.6 - When patents issued1. Patents shall not be issued for any lands belonging to the state, except upon the certificate of the person or officer specially charged with the custody of the patents, setting forth the appraised value per acre, the name of the person to whom sold, the date of sale, the price per acre, the amount paid, the name of the person making final payment, and the name of the person who is entitled to the patent. If a person is entitled to a patent due to an assignment from the original purchaser, the certificate shall set forth fully the assignment and shall be filed and preserved in the land office.2. Whenever the governor is satisfied that the purchase price has been paid by the person to whom the sale has been made and that a patent has not been issued to the purchaser, a patent shall be issued, signed by the governor and secretary of state and recorded by the secretary of state. The passage of seventy-five years from the date of sale without issuance of a patent shall be conclusive proof that the purchase price has been paid.
