Former DHS Secretary Kristi Noem plans to divorce her husband Bryon after 34 years of marriage, her 77-year-old mother told the Daily Mail, saying Noem retained a lawyer in late spring 2026. No divorce petition has appeared in South Dakota court records yet, and neither spouse has confirmed the split — making this a textbook 'gray divorce' still in its pre-filing stage, where South Dakota's fault-and-no-fault hybrid grounds and long-marriage property rules will control the outcome.
The report, first published by TMZ citing the Daily Mail's interview with Noem's mother, follows a scandal over Bryon Noem's alleged private conduct. Because nothing has been filed, everything below is general South Dakota law — not commentary on the Noems' specific strategy, which no attorney can responsibly assess from press reports alone.

Why this matters legally
A 34-year marriage triggers South Dakota's most robust property-division and spousal-support analysis, because length of marriage is a controlling factor courts weigh most heavily in longer unions. South Dakota is an equitable-distribution state, not a community-property state — meaning the court divides the marital estate fairly, which after three-plus decades usually means close to evenly, but not automatically 50/50.
Gray divorce — the term for splits among spouses over 50 — carries higher financial stakes than divorces of younger couples. According to research popularized by Bowling Green State University, the divorce rate for Americans over 50 roughly doubled between 1990 and 2010 and has stayed elevated since. After 34 years, the marital estate typically includes retirement accounts, pensions, real property, and commingled assets accumulated over decades, all of which South Dakota courts treat as marital property subject to division regardless of whose name is on the title.
South Dakota also remains one of the states that allows both fault and no-fault grounds. That distinction matters because a spouse can choose the cleaner no-fault path or plead a fault ground, and the choice can affect tone, timeline, and occasionally the property and support analysis.
How South Dakota law handles this
South Dakota recognizes both fault-based and no-fault divorce under S.D. Codified Laws § 25-4-2. The statutory grounds include adultery, extreme cruelty, willful desertion, willful neglect, habitual intemperance, conviction of a felony, and irreconcilable differences. That last ground — irreconcilable differences under S.D. Codified Laws § 25-4-17.1 — is South Dakota's no-fault option, and it is the path most modern divorces take because it avoids litigating blame. You can read more about how the no-fault divorce process works before deciding which ground fits.
Residency is the threshold requirement. To file for divorce in South Dakota, the filing spouse must be a resident of the state at the time the action is commenced and must remain a resident until the decree is entered, per S.D. Codified Laws § 25-4-30. South Dakota has no fixed months-long waiting period for residency like some states, but courts do require genuine, current residency — an important detail for high-profile spouses who split time across states. Review the general residency requirements rules if your living situation is unsettled.
On property, South Dakota courts divide the marital estate equitably under S.D. Codified Laws § 25-4-44, considering the duration of the marriage, each spouse's age and health, earning capacity, contributions to the marital property, and the value of the estate. After a 34-year marriage, courts rarely draw sharp lines between 'his' and 'her' assets. Spousal support (alimony) is available under S.D. Codified Laws § 25-4-41, which lets a court order either spouse to support the other for a suitable period, weighing the same long-marriage factors. Because retirement assets dominate most gray-divorce estates, dividing pensions and 401(k)s through a qualified domestic relations order becomes central.

Practical takeaways
Even though nothing has been filed in the Noem matter, the situation illustrates steps any long-married spouse should consider before a South Dakota divorce:
-
Confirm residency first. Verify that you meet S.D. Codified Laws § 25-4-30 residency before filing — jurisdiction is the first thing an opposing party will challenge, especially where a spouse has moved for work.
-
Inventory the full marital estate. After 34 years, assets are deeply commingled. Document retirement accounts, real property, business interests, and debts, because South Dakota divides all marital property equitably under S.D. Codified Laws § 25-4-44.
-
Decide fault versus no-fault deliberately. Irreconcilable differences under S.D. Codified Laws § 25-4-17.1 keeps a case cleaner, but a fault ground remains available — talk through the trade-offs with counsel before choosing.
-
Plan for retirement division. Gray divorces hinge on pensions and 401(k)s. A qualified domestic relations order is usually required to split these without triggering taxes and penalties, so raise it early.
-
Map your next steps. Build a personalized divorce roadmap to see the sequence of decisions, then, if the estate is complex, find a divorce attorney who handles high-asset South Dakota cases.
Because circumstances change — including whether a spousal-support award should later be revisited — long-married couples should also understand how a spousal support modification works after the decree, and how the broader divorce process unfolds in South Dakota from filing to final judgment.
