43 U.S.C. § 128 — Division or change of boundaries; continuance of business of original district

When existing land districts are divided to create new ones, or when the President changes district boundaries, all business already underway in the original district continues without interruption or change. This continues until the offices for the new districts are officially opened, as publicly announced under the direction of the Secretary of the Interior. Any public land sale or other disposal that was properly made at a land office is confirmed as valid, even if that land was later made part of a different district by an Act of Congress or an action of the President — as long as the sale does not conflict with an earlier, valid right to the land.
