Former DHS Secretary and ex-Governor Kristi Noem intends to divorce Bryon Noem after 34 years of marriage, her mother Corinne Arnold told the Daily Mail, reporting a Sioux Falls attorney was hired months ago. In South Dakota, a marriage this long triggers equitable division of all marital property and strong spousal-support eligibility under S.D. Codified Laws § 25-4-45.1.

As reported by TMZ and The Advocate, the divorce remains unconfirmed by either spouse, and no paperwork has surfaced in South Dakota court records as of July 2026. This commentary addresses the general South Dakota family-law questions the news raises — not the private strategy of anyone involved.
Why this matters legally
A 34-year marriage is the single biggest legal factor in a South Dakota divorce, because marriage length directly drives both property division and spousal support. South Dakota is an equitable-distribution state, meaning courts divide marital property fairly — not automatically 50/50 — under SDCL § 25-4-45.1. After three-plus decades, courts typically treat nearly everything acquired during the marriage as marital property subject to division, regardless of whose name is on the title.
Marriage duration also expands spousal-support exposure. South Dakota courts consider the length of the marriage, each spouse's earning capacity, age, health, and the standard of living established during the marriage. A 34-year union sits at the far end of that spectrum, where long-term or even indefinite support becomes a realistic outcome. The reported months-long head start on hiring counsel underscores a practical truth: in long marriages, the financial preparation matters as much as the filing itself. Learn how the divorce process unfolds step by step.
How South Dakota law handles this
South Dakota grants divorce on both no-fault and fault grounds, and either path leads to the same property and support analysis. Under SDCL § 25-4-2, recognized grounds include irreconcilable differences (the no-fault route) as well as fault grounds such as adultery, extreme cruelty, willful desertion, and habitual intemperance. Fault does not control property division mathematically, but South Dakota courts may weigh a spouse's conduct as one factor in reaching an equitable result.
Residency is the threshold gatekeeper. Under SDCL § 25-4-30, the plaintiff must be a South Dakota resident at the time the action is commenced and must maintain residency until the divorce is final. Unlike many states, South Dakota imposes no fixed durational waiting period before filing for a resident — a filing can proceed once residency and grounds are established, though SDCL § 25-4-34 sets a 60-day waiting period after service before a decree can be entered. Review the general residency requirements that apply before any South Dakota filing.
On property, South Dakota courts have broad discretion. The statute directs judges to make an equitable division of property owned by the parties, considering the equity and circumstances of each spouse. In a 34-year marriage, factors that typically dominate include the value of the marital estate, each spouse's contribution (including homemaking and career support), the parties' ages and health, and their respective income and earning capacity. Retirement accounts, pensions, and appreciation accumulated across decades are squarely in play, and often require a Qualified Domestic Relations Order to divide. Understanding equitable distribution is central to reading any long-marriage outcome.
Spousal support in South Dakota is governed by SDCL § 25-4-41, which authorizes the court to order maintenance from either spouse to the other. There is no rigid formula; instead, courts weigh the length of the marriage, the parties' earning capacities, financial condition, age and health, and the standard of living during the marriage. Because support orders can later change with circumstances, any award may be revisited — see how spousal support modification works when incomes shift.
Practical takeaways
-
Confirm residency before filing. Under SDCL § 25-4-30, you must be a South Dakota resident when the action begins and remain one until the decree issues — establish this first.
-
Inventory the full marital estate early. In a decades-long marriage, gather documentation on homes, retirement accounts, pensions, business interests, and investments now; equitable division under SDCL § 25-4-45.1 turns on complete financial disclosure.
-
Assess spousal-support exposure realistically. With a 34-year marriage, run the numbers on both paying and receiving maintenance under SDCL § 25-4-41, factoring in earning capacity and the marital standard of living.
-
Budget for the timeline and cost. Expect at least a 60-day post-service waiting period under SDCL § 25-4-34; estimate expenses with our divorce cost estimator and map the phases with the South Dakota divorce timeline tool.
-
Plan the sequence, not just the filing. As the reported early attorney retention illustrates, long-marriage divorces reward preparation; build a personalized divorce roadmap before anyone files.
