Iowa Code § 9G.10: Quitclaim deeds.

Whenever the governor is satisfied by proper record evidence that any tract of land which may have been deeded by virtue of any donation or sale to the state is not the land intended to have been described, and that an error has been committed in making out the transfers, in order that such error may be corrected, the governor is authorized to quitclaim the same to the proper owner thereof, and to receive a deed or deeds for the lands intended to have been deeded to the state originally.
