No durational residency in South Dakota — being a resident when you file is enough — then 60 days running from completed service, not from filing. South Dakota does grant legal separation.
South Dakota divorce follows the same state-run pattern as most of the country, but two features shape almost every negotiation: courts here can divide all property either spouse owns, not just what was built up during the marriage, and every case runs into a mandatory 60-day wait before it can be finalized.
| Residency requirement | Either spouse must be a South Dakota resident (or a servicemember stationed in the state) at the time of filing — there is no minimum length of residency required (SDCL 25-4-30). |
|---|---|
| Grounds | One no-fault ground (irreconcilable differences) or six fault-based grounds: adultery, extreme cruelty, willful desertion, willful neglect, habitual intemperance, or conviction of a felony (SDCL 25-4-2). |
| Waiting period | 60 days — but not from filing. SDCL §25-4-34 runs the clock from completed service of the summons and complaint on the other spouse, so the date you file does not start it. If service is delayed, the 60 days is delayed with it. |
| Legal separation | South Dakota does grant legal separation. It settles the same questions a divorce settles — support, parenting and, depending on the case, property — but leaves the marriage in place, so neither spouse can remarry without a divorce. |
| If you were never married | South Dakota does not create common-law marriage, and living together gives neither partner property or support rights. Claims rest on agreements between you. A common-law marriage validly formed in a state that does create them is generally still recognised. |
| Where you file | The Complaint is filed with the Clerk of Courts at the Circuit Court in the county where either spouse resides. |
| Filing fee | Payable when you file your opening divorce document. Set by regulation and revised from time to time. Filing fees are set by the court and change without notice: check the current schedule on the court's own website before you file, and ask about a fee waiver if the cost is a barrier. |
| Starting forms | UJS-309 (Summons) and UJS-310 (Complaint) for divorce without minor children, or UJS-311/UJS-312 with minor children — plus UJS-232 (Case Filing Statement) and UJS-023 (Financial Statement). UJS-307A is the plaintiff's checklist. |
| Simplified option | Yes — an uncontested case can proceed as a 'Stipulated Divorce' once both spouses sign a UJS-324 Stipulation and Settlement Agreement, avoiding a contested trial. Note: South Dakota abolished new common-law marriages after July 1, 1959, but recognizes common-law marriages validly formed in another state — separation alone has no independent legal status; only divorce ends the marriage. |

Most states start property division by sorting assets into 'marital' (divided) and 'separate' (usually kept by the original owner) — things like an inheritance, a gift, or a house owned before the wedding. South Dakota is one of the few states that doesn't automatically draw that line. Under South Dakota's equitable distribution law, courts generally have authority to divide all property owned by either spouse, regardless of when or how it was acquired, weighing factors like the length of the marriage, each spouse's age and health, and each spouse's contributions. That doesn't mean a separately-owned asset will necessarily be split — judges routinely award such property back to the original owner — but nothing is automatically off the table the way it is in many neighboring states. If a letter from the other side asserts that an asset is simply 'not part of this,' that's a position to note carefully, not a settled fact.
South Dakota also builds in a fixed pause: state law generally requires a waiting period of around 60 days from when the case is filed and served before a divorce can be finalized, even if both spouses agree on everything. That period is often when the real back-and-forth happens — offers, counteroffers, and document requests tend to cluster in this window, which is exactly when it's easiest to lose track of who proposed what.
Divorce cases are filed and heard in South Dakota's Circuit Courts, organized under the state's Unified Judicial System across several judicial circuits. Confirm the correct circuit and any local filing procedures with the clerk of courts or a local family law attorney, since practice can vary somewhat by circuit.
Because South Dakota courts can look at all property either spouse holds, thorough documentation matters even more than in states with a strict separate-property carve-out. Start collecting: several years of tax returns; recent pay statements; statements for every bank, retirement, and investment account; property tax records and mortgage statements for any real estate; vehicle titles; and business records if either spouse is self-employed or owns a company. If you're bringing an asset into the marriage that you'd like the court to consider separately — a pre-marriage account, an inheritance, a gift — pull together the paper trail showing its origin and history now, since that documentation carries real weight in an all-property state.
Save every letter, email, and text exchanged with the other party or their lawyer from the start. In a state with a built-in 60-day window, that correspondence often ends up being the clearest record of what was actually offered, when, and what deadlines were attached — details that are easy to misremember once several letters have arrived.
Child support in South Dakota is calculated using the state's child support guidelines, which weigh both parents' incomes and the parenting time arrangement. Custody and parenting time decisions are made under a best-interests-of-the-child standard, and South Dakota courts generally look favorably on parenting proposals that are specific — schedules, holidays, transportation, decision-making — rather than vague. If a letter proposes a particular custody or support arrangement, note the specifics rather than the general tone; the details are what a lawyer or mediator will need later.
Legal separation is available in South Dakota. It is a court proceeding, and in most respects it runs like a divorce: the court can settle support, parenting arrangements and, depending on the case, the division of property, and the resulting order binds both spouses.
What it does not do is end the marriage. People choose it for a range of reasons — health coverage, religious conviction, immigration status, or simply not being ready — and it leaves the door open to reconciling without starting over.
Two consequences follow. Neither spouse can remarry unless they later obtain a divorce, and modifying the order generally takes the court's approval rather than a private agreement between you. If you expect to divorce eventually, ask what converting the separation into a divorce involves here before you start.
South Dakota does not create common-law marriage. There is no number of years of living together that turns into a marriage here, and none of the divorce machinery on this page applies to a couple who never married — no property division, no spousal support, no residency requirement to satisfy, because there is nothing to dissolve.
What unmarried partners have instead are ordinary civil claims: whatever you agreed between yourselves, in writing or by clear conduct, and claims over property you actually hold jointly. These are argued like any other contract or property dispute rather than as family-law entitlements, and they turn on what can be proved.
One qualification runs the other way and matters. A common-law marriage validly formed in a state that does create them — Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas or Utah — is generally recognised elsewhere. A couple who met that state's test while living there, and later moved here, are married, and separating means divorcing. Children are unaffected either way: custody and child support are decided on the same basis whether or not the parents married.
1) Build your financial picture broadly — remember that in South Dakota, even property you consider 'yours alone' may come into the conversation, so document its origin now rather than later. 2) Get at least one consultation with a local family law attorney early; South Dakota's rules on all-property division and residency can be nuanced enough that general information isn't a substitute for local advice. 3) Expect the 60-day statutory wait and use it productively — it's a natural checkpoint for gathering documents and reviewing offers rather than reacting to them immediately. 4) Confirm current residency and filing requirements with the circuit court clerk, since these can vary by circumstance. 5) Track every date any letter sets, and keep the letters themselves — with an all-property rule and a fixed waiting period both in play, the sequence of who said what and when tends to matter more here than in many other states.
You (or your spouse) must be a South Dakota resident at filing, with no minimum time required. Decide whether you'll file on the no-fault ground of irreconcilable differences or a fault-based ground under SDCL 25-4-2.
Collect details on marriage date, separation, finances, property, debts, and — if applicable — children, since these feed into the Complaint and Financial Statement.
Fill out the Summons and Complaint (UJS-309/UJS-310 without minor children, or UJS-311/UJS-312 with minor children), plus the Case Filing Statement (UJS-232) and Financial Statement (UJS-023). The UJS-307A checklist walks through the full packet.
Submit your forms to the Clerk of Courts in the county where you or your spouse live, and pay the filing fee. If you can't afford it, file UJS-022 to request a fee waiver.
Have the Summons and Complaint formally served on your spouse (the defendant) by someone other than yourself, then file proof of service with the court.
South Dakota requires at least 60 days between filing and the final decree, even in uncontested cases, so use this time to finish paperwork or negotiate terms.
If you and your spouse agree on property, debts, support, and (if applicable) custody, sign a Stipulation and Settlement Agreement (UJS-324). If not, the case proceeds toward a contested hearing before a judge.
Prepare Findings of Fact, Conclusions of Law, and a Judgment and Decree of Divorce (e.g., UJS-326A) reflecting the agreement or the court's rulings, for the judge's signature.
Once the judge signs the Judgment and Decree, your divorce is final; keep certified copies for updating your name, accounts, and records.
No. South Dakota courts generally have authority to consider all property owned by either spouse, but division is equitable, not automatically equal — judges weigh factors like the length of the marriage and each spouse's contributions and circumstances. Confirm how this applies to your situation with a local family law attorney.
South Dakota law generally requires a waiting period of around 60 days from filing and service before a decree can be finalized, even in agreed cases. Confirm current timelines and any exceptions with the circuit court or a local attorney.
Not automatically. Because South Dakota courts can generally consider all property either spouse owns, pre-marriage assets aren't guaranteed to be excluded the way they might be in other states, though courts often still award such property to its original owner. Documenting the asset's origin helps regardless of outcome.
A legal separation in South Dakota settles much of what a divorce settles — support, parenting and, depending on the case, property — and the order binds both spouses. The difference is that it does not end the marriage, so neither spouse can remarry without later obtaining a divorce. People use it for health coverage, religious reasons, immigration status, or because they are not ready to divorce. Changing the order generally requires the court's approval.
No. South Dakota does not create common-law marriage, and living together for any length of time gives neither partner property division nor spousal support. Unmarried partners rely instead on agreements between themselves and on claims over jointly held property, argued as ordinary civil matters. One important exception: a common-law marriage validly formed in a state that does create them — such as Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas or Utah — is generally recognised here, so that couple would need a divorce. Custody and child support apply regardless of marriage.
