South Dakota grants no-fault divorces on the ground of irreconcilable differences, but only when both spouses agree or the defendant fails to appear. The plaintiff must be a South Dakota resident at the time of filing, and there is no minimum residency duration required before you can file. No separation period is required.
Grounds for divorce in South Dakota
South Dakota law lists seven grounds for divorce under SDCL 25-4-2. The no-fault ground is irreconcilable differences, meaning the marriage has broken down to the point that it cannot be repaired. Unlike most states, South Dakota's irreconcilable-differences ground carries an important limitation: it is only available when both spouses consent to the divorce, or when the defendant spouse fails to appear after being properly served.
If your spouse contests the divorce and refuses to consent, you cannot use irreconcilable differences as your ground. In that situation, you must prove one of the fault grounds listed in SDCL 25-4-2: adultery, extreme cruelty, willful desertion, willful neglect, habitual intemperance (alcohol or substance abuse), or conviction of a felony. Three of those are not available right away. Under SDCL 25-4-17, willful desertion, willful neglect, and habitual intemperance must each have continued for one year before any of them becomes a ground for divorce, so a spouse who cannot get consent may have to wait out that year before filing on one of them. This mutual-consent requirement makes South Dakota one of a small number of states where a contested, unilateral no-fault divorce is not available.
Fault grounds require evidence. Extreme cruelty covers physical or mental abuse that makes continued cohabitation unsafe or unreasonable. Willful desertion means one spouse intentionally abandoned the other without justification, and the abandonment must have run a full year before it supports a divorce. A Circuit Court judge weighs the evidence on any contested fault ground. If your spouse will not agree to the divorce, get a free case evaluation from a South Dakota family lawyer on which fault ground you can prove (attorney advertising).
The seven causes in SDCL 25-4-2 are not quite the whole list. SDCL 25-4-18 adds a separate discretionary ground: where a spouse has had incurable, chronic mania or dementia for five years or more while confined by order of a court of record or of the Board of Mental Illness, the court may grant a divorce. That ground uses archaic language, is rarely invoked, and leaves the decision to the judge.
Residency requirement
To file for divorce in South Dakota, the plaintiff must be a resident of the state at the time the action is commenced. South Dakota imposes no minimum prior duration, so you do not need to have lived in the state for six months or a year before filing. You simply need to be a resident when you file the petition.
The residency requirement is notably permissive compared to most states, which commonly require six months or longer. Military service members stationed in South Dakota may also satisfy the residency requirement. Divorce cases are filed and heard in the Circuit Court for the county where the plaintiff resides.
Waiting period and separation
These two concepts are frequently confused. South Dakota has a waiting period but no separation requirement. The 60-day waiting period under SDCL 25-4-34 begins after the defendant spouse has been properly served with the divorce papers. No hearing may be held, and no final judgment may be entered, until those 60 days have passed.
The waiting period is a cooling-off clock. It does not require you to live apart from your spouse during those 60 days. You may remain in the same household if you choose. The clock simply prevents the court from finalizing the divorce too quickly.
A separation requirement is a different thing entirely: it would require you to live physically apart from your spouse for a set period before you could even file, or before the court could grant the divorce. South Dakota imposes no such requirement. You can file at any time, and the only delay built into the process is the 60-day post-service wait.
How property is divided
South Dakota is an equitable distribution state. When spouses cannot agree on how to divide property, the Circuit Court divides marital property in a manner that is fair and equitable under all the circumstances, which is not necessarily a 50/50 split. The court weighs factors such as the length of the marriage, each spouse's economic circumstances, contributions to the marital estate, and any other relevant factors.
Equitable distribution applies only to marital property, meaning assets and debts acquired during the marriage. Separate property, which includes assets owned before the marriage, inheritances, and gifts received by one spouse, generally stays with that spouse. However, if separate property has been commingled with marital assets or if the other spouse contributed to its growth, a court may reconsider how to classify it.
South Dakota is not one of the nine community-property states. Community-property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin) split marital assets roughly 50/50 by default. South Dakota's equitable-distribution standard gives judges more discretion.
Alimony, custody, and child support
Divorce proceedings in South Dakota can include decisions about spousal support (alimony), child custody, and child support. These issues are often resolved in the same case as the divorce itself, either through a negotiated settlement or a court ruling. Courts have broad discretion to award alimony based on factors like the length of the marriage, each spouse's earning capacity, and the standard of living during the marriage.
Child custody in South Dakota is governed by the best-interests-of-the-child standard. Courts consider factors including each parent's relationship with the child, stability, and the child's own preferences if the child is of sufficient maturity. Joint custody is common when both parents are able and willing to cooperate.
Child support is calculated using South Dakota's income shares guidelines, which factor in both parents' incomes and the number of children. Estimate your payment with our South Dakota child support calculator.

How to file for divorce in South Dakota
Step 1: Confirm residency. Verify that you are a South Dakota resident at the time you plan to file. No minimum prior duration is required.
Step 2: Choose the correct ground. If both spouses agree, file on irreconcilable differences. If your spouse will not consent and is likely to contest, you must identify a fault ground you can prove (adultery, extreme cruelty, desertion, neglect, habitual intemperance, or felony conviction). Check the timing before you file: SDCL 25-4-17 requires that desertion, neglect, and habitual intemperance each have continued for one year first.
Step 3: File the petition. Submit a Complaint for Divorce (or Petition for Divorce) in the Circuit Court for the county where you reside. You will also file a summons and any required financial disclosure forms. The clerk will assign a case number.
Step 4: Serve your spouse. The defendant must be formally served with the summons and complaint. Service may be by personal delivery, an officer, or another court-approved method. The 60-day waiting period begins once proper service is completed.
Step 5: Await the response. Your spouse has a set time (generally 30 days) to file an answer or response. If they do not respond, you may proceed by default, which is one scenario where irreconcilable differences becomes available even without active consent.
Step 6: Exchange financial disclosures. Both parties must disclose assets, debts, income, and expenses. This information forms the basis for property-division and support negotiations or rulings.
Step 7: Settle or go to trial. If you and your spouse reach full agreement on all issues (property, support, custody, child support), you can submit a stipulated agreement and request a final decree. If issues remain disputed, the court holds hearings or a trial and issues rulings.
Step 8: Obtain the final decree. Once the 60-day waiting period has expired and all issues are resolved, the Circuit Court judge signs the Decree of Divorce. The marriage is legally ended on the date of the decree.

Frequently Asked Questions
How long does it take to get a divorce in South Dakota?
The minimum is about 60 days from the date your spouse is served, because SDCL 25-4-34 bars any hearing or final judgment before that period expires. An uncontested divorce where both spouses agree on all terms can often be finalized within a few months. Contested cases involving disputed property or custody can take a year or more.
How much does a divorce cost in South Dakota?
The court filing fee is fixed by statute and is the same in every South Dakota county: $25 to file a civil case for jury or court trial (SDCL 16-2-29), a $50 divorce filing fee (SDCL 16-2-45), and a $40 unified judicial system court automation surcharge (SDCL 16-2-39), for a total of $115. Serving your spouse costs extra. If you hire an attorney, costs depend on whether the case is contested. An uncontested divorce with an attorney may cost a few thousand dollars in legal fees; a heavily contested case can cost significantly more. Self-represented (pro se) parties pay only court filing and service fees.
Do I need a reason to divorce in South Dakota?
Yes, but the standard is low if both spouses agree. If you and your spouse both consent, irreconcilable differences is sufficient and no fault needs to be shown. If your spouse contests the divorce and will not agree, you must prove one of the statutory fault grounds, such as adultery, extreme cruelty, desertion, neglect, habitual intemperance, or felony conviction. Three of those carry a waiting requirement: under SDCL 25-4-17, desertion, neglect, and habitual intemperance must each have continued for one year before they can be used.
Is South Dakota a community property state?
No. South Dakota is an equitable distribution state. Courts divide marital property fairly under the circumstances, which is not necessarily an equal 50/50 split. Only nine states use the community-property system: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.
How long do I have to be separated to divorce in South Dakota?
South Dakota has no separation requirement. You do not need to live apart from your spouse for any period before filing or before the court can grant the divorce. The only built-in delay is the 60-day waiting period after service of process.
Can I get divorced without my spouse agreeing in South Dakota?
Not on the irreconcilable-differences ground. That ground is only available when both spouses consent, or when the defendant defaults by failing to appear. If your spouse actively contests the divorce, you must prove one of the fault grounds listed in SDCL 25-4-2, such as extreme cruelty or adultery.
Do I have to live in South Dakota to file for divorce?
You must be a South Dakota resident at the time you file. However, there is no minimum prior residency duration; you do not need to have lived in the state for six months or any other set period before filing, as long as you are domiciled there when you commence the action.
Updates
Added the one-year continuity requirement that South Dakota law imposes on desertion, neglect, and habitual intemperance as divorce grounds, corrected the filing-fee answer to reflect the $115 fee set uniformly by statute rather than varying by county, and noted the separate discretionary ground under SDCL 25-4-18.
