This bill establishes a legal framework for counties in Iowa to secede from the state by adopting an ordinance. Once an ordinance is enacted, the county will no longer be considered a political subdivision of Iowa, and its residents will not be subject to Iowa's laws or Constitution. However, any state-owned property within the seceding county will remain under the ownership and control of the state of Iowa. The ordinance must have an effective date of at least one year after its adoption.

Additionally, the bill stipulates that a county seeking to secede must obtain approval from the federal government and either another state to join or federal approval to become its own state or territory. This requirement ensures that the process of secession is regulated and contingent upon higher governmental authority.
