Yes. South Dakota offers two ways for spouses to stay married while living apart under court orders: a legal separation, which SDCL 25-4-17.2 lets the court decree when it finds irreconcilable differences, and an action for separate maintenance under SDCL 25-4-40, which can rest on any ground for divorce.
Information last verified on 2026-10-08. This article has not been reviewed by a licensed lawyer.
Jurisdiction scope: This article covers legal separation and separate maintenance under South Dakota law, SDCL chapter 25-4 (Divorce and Separate Maintenance) and SDCL 25-2-13 on separation agreements. It does not cover support amounts, property division in a separation decree, court forms, or other states' law. For divorce grounds and procedure, see South Dakota divorce laws.
Can you get legally separated in South Dakota?
Yes. Chapter 25-4 of the South Dakota Codified Laws is titled "Divorce and Separate Maintenance," and it provides two routes.
| Legal separation | Separate maintenance | |
|---|---|---|
| Statute | SDCL 25-4-17.2 | SDCL 25-4-40 |
| Ground | Irreconcilable differences that have caused the irremediable breakdown of the marriage | "Any grounds which would be grounds for divorce" |
| Consent | Both spouses must consent on the irreconcilable-differences ground, unless one has not made a general appearance | This page does not cover whether the 25-4-17.2 consent rule applies to separate maintenance on the irreconcilable-differences ground |
| What the court can award | A decree of separation; if the case is continued for a possible reconciliation (up to 30 days), interim orders on support, custody, attorney fees and property preservation | Temporary alimony, suit money, and permanent support for a spouse and the children |
Legal separation under SDCL 25-4-17.2
The key sentence of SDCL 25-4-17.2 reads:
"If from the evidence at the hearing, the court finds that there are irreconcilable differences, which have caused the irremediable breakdown of the marriage, it shall order the dissolution of the marriage or a legal separation."
Under the same section, the court may not decree a legal separation or a divorce on the irreconcilable-differences ground without the consent of both parties, unless one party has not made a general appearance.
If it appears there is a reasonable possibility of reconciliation, section 25-4-17.2 requires the court to continue the case for up to thirty days. During that continuance:
"the court may enter any order for the support and maintenance of the parties, the custody, support, maintenance, and education of the minor children of the marriage, attorney fees, and for the preservation of the property of the parties."
Afterward, "At any time after the termination of the thirty-day period, either party may move for the dissolution of the marriage or a legal separation, and the court may enter its judgment decreeing the dissolution or separation."
Separate maintenance under SDCL 25-4-40
Separate maintenance is the other route. SDCL 25-4-40 provides:

"An action for separate maintenance may be maintained without request for divorce, upon any grounds which would be grounds for divorce, and in such cases the court shall have power to award temporary alimony, suit money, and permanent support for a spouse and the children of the parties, or any of them, by the other spouse."
SDCL 25-4-2 lists seven grounds for divorce, each of which can also support separate maintenance under 25-4-40: "(1) Adultery; (2) Extreme cruelty; (3) Willful desertion; (4) Willful neglect; (5) Habitual intemperance; (6) Conviction of felony; (7) Irreconcilable differences."
A related rule covers a divorce case that fails. Under SDCL 25-4-39, "Though judgment of divorce is denied, the court may in an action for divorce provide for maintenance of a spouse and the children of the parties, or any of them, by the other spouse."
Residency, waiting period and the automatic restraining order
Residency. SDCL 25-4-30 provides: "The plaintiff in an action for divorce or separate maintenance must, at the time the action is commenced, be a resident of this state, or be stationed in this state while a member of the armed services." The plaintiff need not keep that residence afterward to receive the decree. The section ties residency to the day the case begins and does not state a minimum period.
Sixty-day wait. Under SDCL 25-4-34, "An action for divorce or separate maintenance shall not be heard, tried, or determined by the court until at least sixty days have elapsed from the completed service of the plaintiff's summons and complaint." During that period the court may issue orders under 25-4-38 and 25-4-45.
Automatic restraining order. SDCL 25-4-33.1 provides that, upon the filing of a summons and complaint for divorce or separate maintenance and personal service, a temporary restraining order is in effect against both parties. It restrains both spouses from "transferring, encumbering, concealing, or in any way dissipating or disposing of any marital assets, without the written consent of the other party or an order of the court, except as may be necessary in the usual course of business or for the necessities of life," and requires notice of and an accounting for extraordinary expenditures. It also bars molesting or disturbing the other spouse, removing a minor child from the state without written consent or a court order, and most changes to insurance coverage. It lasts until the final decree, dismissal, or further court order.
What a separation does and does not do
You stay married. SDCL 25-4-1 provides that "Marriage is dissolved only: (1) By the death of one of the parties; or (2) By the judgment of a court of competent jurisdiction decreeing a divorce of the parties." Section 25-4-17.2 itself treats "dissolution" and "legal separation" as different outcomes.
Property is less clear. The equitable division statute, SDCL 25-4-44, begins "When a divorce is granted." This page does not cover whether or how a South Dakota court divides property in a legal separation or separate maintenance decree; ask a South Dakota lawyer. During the 25-4-17.2 continuance, the court may enter orders "for the preservation of the property of the parties."
Inheritance. Under SDCL 29A-2-802, "A decree of separation that does not terminate the status of husband and wife is not a divorce" for purposes of that section, which says who is not a surviving spouse. SDCL 29A-2-804 says the same for its rule that a divorce revokes gifts to a former spouse in a will or beneficiary designation. Under 29A-2-213(d), unless it provides otherwise, a complete property settlement made after or in anticipation of separation waives each spouse's elective share, homestead allowance, exempt property and family allowance and renounces benefits that would otherwise pass by intestate succession or under a will signed before the settlement.
For support amounts, see South Dakota alimony laws. For custody, see South Dakota child custody laws.
Separation agreements
Spouses do not need a court case to agree on a separation. SDCL 25-2-13 provides that they "may agree in writing to an immediate separation and may make provision for the support of either of them and of their children during such separation. The mutual consent of the parties is sufficient consideration for such separation agreement."
Moving from separation to divorce
Within a 25-4-17.2 case, either spouse may move for dissolution of the marriage after the thirty-day period, and the court may enter its judgment decreeing the dissolution or separation. This page does not cover a procedure for converting a final legal separation or separate maintenance decree into a divorce later.

South Dakota's list of divorce grounds in 25-4-2 does not include living apart for a set period. A spouse who later wants a divorce relies on one of the seven grounds in 25-4-2, or on the separate discretionary ground in 25-4-18 for a spouse's incurable chronic mania or dementia lasting five years or more while under court-ordered confinement.
Court forms
This page does not cover court forms for legal separation or separate maintenance in South Dakota. The clerk of court can explain how to start a case.
