Kristi Noem and Bryon Noem pictured together before their 2026 divorce filing.
Kristi Noem has filed for divorce from her husband, Bryon Noem, after 34 years of marriage. The former South Dakota governor and former Department of Homeland Security secretary filed the paperwork on Sept. 28 in Hamlin County, South Dakota, where the couple has deep family and personal ties.
The filing marks a significant change for a couple who have been together since their school years and raised three children. Court records list irreconcilable differences as the stated grounds for the divorce.
Kristi Noem Files Divorce Papers in South Dakota
Noem filed the divorce case in Hamlin County, the South Dakota community where she and Bryon Noem grew up and later built their family.
The couple married in 1992 after meeting at Hamlin High School. Their marriage continued through Noem’s rise from a South Dakota farmer and rancher to a state legislator, member of Congress and governor, followed by her move into the federal government.
The divorce filing does not publicly identify a specific event as the reason the marriage ended. Instead, irreconcilable differences are listed as the legal grounds.
As of Sept. 29, attorneys representing Kristi and Bryon Noem had not publicly provided a detailed statement about the case.
The Couple Has Three Adult Children
Kristi and Bryon Noem share three children: daughters Kassidy and Kennedy and son Booker.
Their daughters have also started families of their own, making Kristi and Bryon grandparents. For many years, Bryon’s role was largely centered around their family and his own professional work while Kristi’s political career increasingly placed the family in the public eye.
Bryon grew up in Hamlin County and attended Hamlin High School, where he met Kristi Arnold, who would later become governor of South Dakota.
After college, Bryon worked as a basketball coach and spent time working on his family’s farm. He later moved into sales and eventually operated a crop insurance business near Castlewood, South Dakota.
Bryon Noem Faced Public Scrutiny Earlier This Year
The divorce filing comes after months of intense public attention surrounding Bryon Noem.
Earlier in 2026, The Daily Mail published photographs and messages that it said were connected to Bryon’s participation in online fetish forums. The reports described alleged private conversations and activity involving a fetish community.
The allegations received widespread media attention because of Kristi Noem’s prominent political position and the couple’s long public history together.
Reports also alleged that Bryon had spent substantial amounts of money in online chatrooms associated with a fetish known as “bimbofication,” which involves exaggerated feminine imagery and role-playing.
Those details came from media reporting about private material and should be distinguished from facts established through the divorce proceedings. The divorce filing itself cites irreconcilable differences and does not state that the reported online activity was the legal reason for the separation.
Kristi Noem’s Representative Said She Was Blindsided
When reports about Bryon’s alleged online activity surfaced in March, a representative for Kristi Noem said she had been blindsided by the revelations.
The representative also said Noem was devastated by the reports and asked for privacy.
The public attention surrounding the allegations added another personal controversy to a period when Noem was already facing major changes in her political career.
The subsequent divorce filing now formally confirms that the marriage is moving into the legal separation process.
Noem’s Mother Had Previously Spoken About the Divorce
The possibility of a divorce had been publicly discussed before the court paperwork was filed.
In July, Kristi Noem’s mother, Corinne Arnold, told The Daily Mail that Kristi and Bryon were divorcing. At the time, however, no divorce papers had yet been filed.
Arnold said she felt badly about the situation and indicated that the decision had already become known within the family.
The Sept. 28 court filing now provides the formal legal record behind those earlier reports.
Kristi Noem’s Political Career Has Changed Dramatically
The divorce comes during a period of major transition in Noem’s professional life.
Noem entered politics in 2006 after winning a seat in the South Dakota House of Representatives. In 2010, she won election to the U.S. House, where she represented South Dakota for several terms.
She later ran for governor and won South Dakota’s gubernatorial election in 2018, taking office in 2019. She won reelection in 2022.
Her national profile increased further after Donald Trump selected her to lead the Department of Homeland Security in his second administration.
Noem’s time at DHS became the subject of significant political and media attention before she left the position in 2026. She was subsequently assigned to a different federal role involving the Shield of the Americas initiative.
Bryon Noem Maintained a Lower Public Profile
While Kristi Noem became a nationally recognized political figure, Bryon generally remained outside the center of political life.
He supported his wife’s career while maintaining his own professional interests in South Dakota. His background in agriculture, coaching and crop insurance remained separate from the increasingly national focus surrounding Kristi’s political work.
The couple nevertheless appeared together at public events during Noem’s years in elected office and in Washington.
Their relationship was therefore familiar to many South Dakota voters and political observers, even though details of their private life were generally limited.
Other Personal Allegations Surrounding Noem Remain Separate
The reporting around the Noems’ marriage has also included allegations involving Kristi Noem and Corey Lewandowski, a political adviser who worked with her during her time in the Trump administration.
Both Noem and Lewandowski have denied reports of an extramarital romantic relationship.
During a congressional hearing earlier this year, Noem was questioned about the allegations and dismissed the questions as “tabloid garbage.”
Those claims are separate from the divorce filing and should not be presented as an established explanation for the end of Noem’s marriage.
The court filing itself cites irreconcilable differences without providing a more specific explanation.
What the Divorce Filing Means Going Forward
The Sept. 28 filing begins the formal divorce process, but it does not by itself resolve issues that could arise during the case.
Future court filings could provide information about property, financial matters or other aspects of the separation. Until those details become part of the public record, speculation about the couple’s private arrangements remains just that.
For now, the confirmed details are straightforward: Kristi Noem filed for divorce from Bryon Noem in Hamlin County after 34 years of marriage, and the petition cites irreconcilable differences.
A Marriage That Spanned Noem’s Rise in Politics
Kristi and Bryon Noem’s marriage began long before Kristi entered public office.
They met as teenagers in South Dakota, married in 1992 and raised three children together. Over the following decades, Kristi’s career took her from agriculture and state politics to Congress, the South Dakota governor’s mansion and eventually the federal government.
The divorce filing now brings that chapter of their personal lives into a formal legal process.
More details may emerge as the case progresses, but the current public record does not establish a specific cause beyond the irreconcilable differences cited in the filing.
