162.623—What will BIA do if a tenant holds over after the expiration or cancellation of a lease?
If a tenant remains in possession after the expiration or cancellation of a lease, we will treat the unauthorized use as a trespass. Unless we have reason to believe that the tenant is engaged in negotiations with the Indian landowners to obtain a new lease, we will take action to recover possession on behalf of the Indian landowners, and pursue any additional remedies available under applicable law.
