Iowa Code § 9G.11
In cases where lands have been granted to the state of Iowa by Act of Congress, and certified lists of lands inuring under the grant have been made to the state by the commissioner of the general land office, as required by Act of Congress, and such lands have been granted, by Act of the general assembly, to any person or company, and such person or company shall have complied with and fulfilled the conditions of the grant, the secretary of state is hereby authorized to prepare, on the application of such person or company, or on the application of a party claiming title to any land through such person or company, a list or lists of lands situated in each county inuring to such applicant, from the lists certified by the commissioner of the general land office, as aforesaid, which shall be signed by the governor of the state, and attested by the secretary of state, with the state seal, and then be certified to by the secretary to be true and correct copies of the lists made to this state, and deliver them to such applicant, who is hereby authorized to have them recorded in the proper county, and when so recorded they shall be notice to all persons the same as deeds now are, and shall be evidence of title in such grantee, or the grantee's assigns, to the lands therein described, under the grant of Congress by which the lands were certified to the state, so far as the certified lists made by the commissioner aforesaid conferred title to the state; but where lands embraced in such lists are not of the character embraced by such Acts of Congress or the Acts of the general assembly of the state, and are not intended to be granted thereby, the lists, so far as these lands are concerned, shall be void; but lands in litigation shall not be included in such lists until the actions are determined and such lands adjudged to be the property of the company; nor shall the secretary include, in any of the lists so certified to the state, lands which have been adjudicated by the proper courts to belong to any other grant, or adjudicated to belong to any county or individual under the swampland grant, or any homestead or pre-emption settlement; nor shall said certificate so issued confer any right or title as against any person or company having any vested right, either legal or equitable, to any of the lands so certified.
