Getting a divorce in South Dakota starts with one requirement most states make harder: you only need to be a resident of the state on the day you file. There is no six-month or one-year waiting clock before you can start the case. The court filing fee is $97, your spouse must be formally served with the papers, and no judge can finalize the divorce until at least 60 days after that service is complete. Everything else — how property is split, how custody is set, how long support lasts — depends on your facts and whether you and your spouse agree.
Who Can File and on What Grounds
You can file as soon as you are a South Dakota resident. Military members stationed in the state can also file, even if their legal residence is elsewhere.1South Dakota Legislature. South Dakota Codified Law 25-4-30 – Residence Requirements for Divorce or Separate Maintenance
South Dakota recognizes seven grounds for divorce. The no-fault option is irreconcilable differences, and it is by far the most common. You do not need to prove anyone did anything wrong. The six fault grounds are adultery, extreme cruelty, willful desertion, willful neglect, habitual intemperance, and conviction of a felony.2South Dakota Legislature. South Dakota Codified Law 25-4-2 – Grounds for Divorce You can file on irreconcilable differences alone or combine it with a fault ground. If your spouse contests the fault ground, the court will hold a hearing where you have to prove it with evidence.3South Dakota Unified Judicial System.

Forms, Filing, and Serving Your Spouse
The South Dakota Unified Judicial System publishes the forms online, and the Clerk of Courts in any county has paper copies. You will need a Summons, a Complaint for Divorce, and a Financial Statement.4South Dakota Unified Judicial System. Divorce Without Children Forms A separate set of forms exists for divorces involving minor children.5South Dakota Unified Judicial System. Divorce With Children Forms
Most of your preparation time will go into the Financial Statement. It asks for every asset you hold individually and jointly, including bank accounts, retirement accounts, and real estate, along with income documentation and monthly expenses. Pull pay stubs, tax returns, and account statements together before you start the form. It saves repeat trips to the courthouse.
Filing the Summons and Complaint with the Clerk of Courts costs $97.6South Dakota Unified Judicial System. Guide to Filing Fees and Court Costs – Civil Filings Only After filing, your spouse has to be formally notified through service of process. The sheriff’s office or a private process server handles this most often, delivering the papers in person. Any credible person over 18 who is not involved in the case can also serve them. If your spouse is cooperative, they can sign an Admission of Service form instead, which avoids hiring a server altogether.7South Dakota Unified Judicial System. Starting a Court Action If your spouse cannot be located after a genuine search, you can ask the court to allow service by publication in a newspaper.
The 60-Day Waiting Period
Once service is complete, state law prohibits the court from hearing, trying, or deciding the case for 60 days.8South Dakota Legislature. South Dakota Codified Law 25-4-34 – Waiting Period Before Trial of Divorce and Separate Maintenance Actions Even a fully agreed divorce cannot be finalized sooner.
The 60 days are useful, though. The court can issue temporary orders during that window: temporary spousal support so the lower-earning spouse can cover living expenses or legal fees,9South Dakota Legislature. South Dakota Codified Law 25-4-38 – Alimony Pending Action temporary custody arrangements that reflect each parent’s existing involvement with the child,10South Dakota Legislature. South Dakota Codified Law 25-4A-13 – Temporary Custody Orders and orders protecting property while the case is pending. If your case is contested, expect the real timeline to run several months beyond the 60-day minimum.
Dividing Property
South Dakota is an equitable-division state. The court can divide all property belonging to either or both spouses, no matter whose name is on the title.11South Dakota Legislature. South Dakota Codified Law 25-4-44 – Division of Property Between Parties Equitable means fair, not necessarily equal. A 50/50 split is not required.
Judges have broad discretion, and South Dakota courts weigh factors like the length of the marriage, each spouse’s age and health, each spouse’s contribution to the marital estate (including homemaking), earning capacity, and the value of property each person brought in. A long marriage with a stay-at-home parent produces a very different outcome than a short marriage between two working professionals.
Spousal Support
The court can order one spouse to pay support to the other for life or for a shorter term, considering the circumstances of both parties.12South Dakota Legislature. South Dakota Codified Law 25-4-41 – Allowance for Support When Divorce Granted In practice, the court looks at earning capacity, the marital standard of living, and whether the receiving spouse needs time or training to become self-supporting. Most awards in South Dakota are rehabilitative — long enough to let the receiving spouse rebuild earning power, not permanent. Support orders can be modified later if circumstances change significantly, and if the receiving spouse has a sizeable separate estate, the court may decline to order support at all.
Custody, Parenting Plans, and Child Support
Custody decisions in South Dakota turn on the best interests of the child, with attention to the child’s emotional, mental, and moral welfare. Neither parent has an automatic priority. A child who is old enough to express a thoughtful preference may be heard, but no preference is binding.13South Dakota Legislature. South Dakota Codified Law 25-4-45 – Child Custody Provisions
When you file a divorce involving children, you must also file and serve the South Dakota Supreme Court’s standard parenting guidelines. These become a court order automatically once service is complete, and they cover noncustodial parenting time, weekends, holidays, birthdays, and summer schedules.14South Dakota Legislature. South Dakota Codified Law 25-4A-11 – Filing and Service of Standard Guidelines If both parents agree on something different, they can submit a signed written plan for court approval, which then replaces the standard guidelines.
Mediation and Parenting Education
In any custody or visitation dispute, the court is required to order mediation and split the cost between the parents. Exceptions apply for cases involving a domestic abuse conviction, an assault conviction against a household member, a documented history of domestic abuse, or situations the court finds inappropriate for mediation.15South Dakota Legislature. South Dakota Codified Law 25-4-56 – Mediation in Custody or Visitation Disputes Mediation does not remove the judge’s final authority; it gives you a chance to reach an agreement first.
Both parents in a case involving custody or parenting time must also complete a court-approved education course about how divorce affects children, within 60 days of the summons and complaint being served.16South Dakota Legislature. South Dakota Codified Law 25-4A-32 – Parenting Education Put this deadline on your calendar the day you are served.
How Child Support Is Calculated
South Dakota uses an income-shares model. The court combines both parents’ monthly net incomes, looks up the total support obligation on a standardized schedule based on the number of children, and divides that obligation proportionally. The noncustodial parent’s share becomes the ordered amount.17South Dakota Legislature. South Dakota Codified Law 25-7-6.2 – Support Obligation Schedule
The schedule is a starting point. Either parent can ask the court to deviate based on a child’s special medical or educational needs, financial hardship, or a parent’s voluntary unemployment. If the total support obligation exceeds 50 percent of the paying parent’s monthly net income, hardship is presumed, though the other parent can try to rebut that presumption.18South Dakota Legislature. South Dakota Codified Law 25-7-6.10 – Deviation from Support Obligation Schedule Payments are often processed through the Division of Child Support within the South Dakota Department of Social Services, which also helps establish orders and enforce them when a parent falls behind.19South Dakota Department of Social Services.

Retirement Accounts, Health Insurance, and Other Loose Ends
Several financial consequences of divorce sit outside the decree itself but need to be handled before or just after it is signed.
Retirement Accounts and QDROs
Splitting a 401(k) or pension requires a Qualified Domestic Relations Order. Federal law normally prohibits assigning someone else’s retirement benefits to another person, and a QDRO is the specific exception for divorce, child support, and alimony.20Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits The order has to be issued by a state court and must name both the plan participant and the person receiving the benefit, name each plan involved, state the dollar amount or percentage awarded, and state the time period covered. If any of those pieces are missing, the plan cannot honor it.21U.S. Department of Labor. QDROs Chapter 1 – Qualified Domestic Relations Orders An Overview IRAs do not require a QDRO, but they still need a specific transfer process to avoid tax penalties.
Health Insurance Through COBRA
If you are covered under your spouse’s employer-sponsored health plan, divorce is a qualifying event under federal COBRA law. You can continue the same coverage for up to 36 months after the divorce is finalized, provided the employer has 20 or more employees.22Office of the Law Revision Counsel. 29 U.S. Code 1163 – Qualifying Event You pay the full premium plus a 2 percent administrative fee. You must notify the plan administrator within 60 days of the decree becoming final, and once the administrator sends election paperwork, you have 60 more days to elect coverage. Miss either deadline and you can lose the right permanently.
Social Security and the 10-Year Rule
If your marriage lasted at least 10 years, you may be eligible for Social Security benefits based on your former spouse’s earnings record. You must be at least 62, currently unmarried, and your ex must be eligible for retirement or disability benefits; if your ex has not yet filed, you must also have been divorced at least two years.23Office of the Law Revision Counsel. 42 USC 402 – Old-Age and Survivors Insurance Benefit Payments At full retirement age the benefit can reach 50 percent of your ex’s primary insurance amount. Claiming on your ex’s record does not reduce their benefits and does not require their permission. A marriage that ends at nine years and eleven months leaves both spouses permanently ineligible, so if you are close to the 10-year mark, the timing of the filing deserves real thought.
Federal Taxes
Your filing status for the whole tax year depends on your marital status on December 31. If your divorce is final by that date, you file as single or, if eligible, head of household, not jointly.24Internal Revenue Service. Filing Taxes After Divorce or Separation For parents, the custodial parent (the one the child lived with for more nights) generally claims the child, but the custodial parent can release the claim using IRS Form 8332, letting the other parent take the child tax credit for one year or multiple years.25Internal Revenue Service. Form 8332 – Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent If you negotiate this, spell out in the decree which parent claims which child and in what years.
Restoring a Former Name
The court can restore a maiden name or any name you legally used before the marriage as part of the decree. Request it in your complaint, or either party can ask before the decree is signed.26South Dakota Legislature. South Dakota Codified Law 25-4-47 – Restoration of Former Name The decree itself then serves as the legal document you present to update your driver’s license, Social Security card, and other identification, which is much simpler than filing a separate name-change case later.
