Trust and Fee are two statuses of land. Fee land is also called Deeded land. This is the typical land status in the United States. Anyone can own fee land. Trust land is held in trust by the United States for federally recognized tribes (tribal trust land) and citizens of tribes (allotted trust land). Only tribes and their citizens can own trust land.

Wingsprings is allotted trust land. There are no property taxes on trust land. Trust land cannot be used as collatoral to borrow money. Trust land is under the jurisdiction of the tribe and the federal government. Bennett County and the state of South Dakota provide no services on trust land, and therefore incur no expenses related to providing services.
