A compact was signed on November 16, 2001, between the Cheyenne River Sioux Tribe and the South Dakota Secretary of State. This compact allows the Cheyenne River Sioux Tribe to partner with and use the Secretary of State's uniform commercial code filing system.
This compact provides the ability for tribal members to have their collateral perfected, making loans more available from lending institutions and ultimately helping create business and industrial development on the reservation.
