From the Billings Gazette:
The Crow Tribe recently signed an innovative agreement with Montana and the federal government that will make it easier for banks to offer secured loans on the reservation. Essentially, it provides for seizure of personal property used as collateral when a loan is in default. (It does not apply to land held in trust for the tribe or its members.)
In 2004, the Crow Tribe adopted The Crow Finance Protection and Procedures Act, which makes it possible for banks to foreclose on trust property within the reservation. The catch is that at the foreclosure sale, the land can be sold only to the Crow Tribe or to a member of the tribe. If no eligible bidder can meet the price, the lender gets the beneficial title to the property but must continue to try to sell it to a qualified Crow buyer.
Differences in state and tribal law do come with some complications, but they aren’t barriers, said Mike Eakin, who works in the Billings office of Montana Legal Services.
