North Dakota Century Code Title 20.1. Game, Fish, Predators, and Boating § 20.1-03-42. Guiding on prohibited lands

A person may not act as a hunting guide or hunting outfitter on land the person knows is owned by the state unless the appropriate state agency permits or authorizes the guiding or outfitting, on private land enrolled by the department for purposes of hunting, on land in which the department pays in lieu of taxes, on federal lands without being authorized or permitted as required by the appropriate federal agency, or on private lands posted against hunting or trespassing without first informing and obtaining permission from the landowner to conduct guiding or outfitting on the land.   If the landowner did not grant the permission in writing, there is a presumption that the permission did not exist.
