The Union County Courthouse will be closed on Monday, September 5th for the Labor Day Holiday
Union County, created in 1862, organized in 1862, was originally named Cole County for Austin Cole, who was a member of the first Territorial Legislature. Two years later, the boundaries were rearranged and the name changed to Union because of sentiment for the Union side of the civil war. The county seat is located in Elk Point, and it also includes the communities of Alcester, Beresford, Dakota Dunes, Jefferson, & North Sioux City. We have a population of just under 15,000 people. The county is bordered by Iowa and the Big Sioux River on it’s Eastern side & Nebraska and the Missouri River on it’s Southern side. Interstate 29 runs through the county from North to South.
