How to File for Divorce in South Dakota When Your Spouse Won't Sign

If your spouse refuses to sign the Admission of Service or won't cooperate with the divorce at all, you can still get divorced in South Dakota — you just can't use the cheapest, fastest path. The process shifts from voluntary admission to personal service by a sheriff or process server, and if your spouse never files an Answer within 30 days, you proceed through the default judgment track. It takes longer, costs more, and requires a brief court hearing, but your spouse cannot block you from getting divorced by simply refusing to participate.

Here's the critical distinction most resources miss: your spouse refusing to sign the Admission of Service is not the same as contesting the divorce. They're refusing to acknowledge receipt of papers — a procedural step — not objecting to the divorce itself. The fix is switching service methods. If they also fail to file a formal Answer with the court within 30 days of being served, you proceed to default. A formal Answer that disputes the divorce terms — whether the no-fault grounds, parenting time, property, or debts — can make the case contested.

The Three Paths Based on What Your Spouse Does

Path 1: Spouse Ignores the Admission of Service (Most Common)

You send or deliver the Summons, Complaint, and Admission of Service form (UJS-315 or UJS-317) to your spouse. Under SDCL § 15-6-4(i), they have 20 days to sign and return the Admission. If 20 days pass with no response:

What to do next: Arrange personal service through the county sheriff's office or a private process server. The statutory sheriff fee is $50 plus mileage (typically $10–$12 additional). A private process server may charge $50–$75 depending on location and difficulty of locating the defendant.

Important: Under SDCL § 15-6-4(i), if the defendant had no good cause for failing to return the signed Admission, the court can order them to pay the costs of personal service. Keep your mailing records and the unsigned Admission form as evidence.

Path 2: Spouse Can't Be Found

If your spouse has moved without leaving a forwarding address or is actively evading service, you can petition for service by publication:

1. Document your search efforts in a sworn affidavit of due diligence (calls, emails, checking with relatives, forwarding address requests)
2. File the affidavit with the court and request an Order for Service by Publication
3. The court designates a legal newspaper in the county where the action was filed
4. The summons must run once per week for four consecutive weeks (28 days)
5. Service is complete on the 28th day after first publication

Publication costs typically run $100–$250 depending on the county and newspaper. After publication service is complete, the defendant gets 30 days to respond. If they don't, you proceed to default.

Key limitation: With service by publication, the court generally cannot rule on spousal support or divide out-of-state assets. If your spouse has assets outside South Dakota, you may need to pursue those through separate proceedings in the relevant state.

Path 3: Spouse Files an Answer and Contests the Divorce Terms

This is the path where your divorce can become genuinely contested. Under SDCL § 25-4-17.2, a South Dakota court cannot grant a no-fault divorce based on irreconcilable differences unless both spouses consent in writing or the defendant fails to make a general appearance. If your spouse files an Answer and explicitly refuses to consent to no-fault grounds, you have two options:

1. Negotiate consent: Many defendants object initially but agree to no-fault terms once they understand the alternative is a trial. Mediation can help.
2. Prove fault grounds: You must amend your Complaint and prove one of six statutory fault-based grounds — adultery, extreme cruelty, willful desertion (1+ year), willful neglect (1+ year), habitual intemperance (1+ year), or felony conviction. This typically requires an attorney.

Most uncooperative spouses fall into Path 1 or 2, not Path 3. Passive non-cooperation (ignoring papers, refusing to engage) actually makes your path easier through default judgment — not harder.

The Default Judgment Process Step by Step

Once the 30-day Answer window expires without a response, and the 60-day waiting period has elapsed (counted from the day after service, not the day you filed):

1. Prepare the default packet: Statement of Default (UJS-321A or UJS-323A for cases with children), Application for Judgment and Decree of Divorce Default (UJS-321B or UJS-323B), and Statement of Mailing (UJS-321D or UJS-323D)
2. Verify military status: Under the Servicemembers Civil Relief Act, you must run a Department of Defense database check and submit a Statement of Military Status (UJS-306) confirming the defendant is not on active duty
3. Schedule the hearing: Contact the Clerk of Courts to schedule a brief default hearing — these are usually 10–15 minutes
4. Attend and testify: You'll need to appear in person. The judge will ask standard questions: your name, how long you've lived in South Dakota, the date of marriage, whether the marriage is irretrievably broken, and whether you're asking the court to approve the terms in your proposed decree
5. Bring your proposed decree: Have the Default Judgment and Decree of Divorce (UJS-322A or UJS-322B) drafted and ready for the judge's signature

Who This Is For

• Filers whose spouse is passively uncooperative — ignoring paperwork, refusing to engage, but not actively contesting the divorce
• People whose spouse has moved out of state or can't be located
• Self-represented filers who want to understand the full uncooperative-spouse path before paying a sheriff or process server
• Anyone who assumed their spouse's refusal to sign meant they couldn't get divorced

Who This Is NOT For

• People facing active opposition from a spouse who has hired an attorney and filed an Answer contesting the divorce — that's a contested case requiring legal representation
• Situations involving domestic violence or protective orders — these need immediate legal help, not a self-help filing process
• Spouses who simply haven't responded yet — wait the full 20 days for the Admission of Service before escalating

Common Timeline for the Uncooperative-Spouse Path

Total time from filing to final decree: roughly 3–4 months if everything goes smoothly. Compare this to the cooperative path (where your spouse signs the Admission immediately), which typically takes about 2.5–3 months.

The Cost Difference

The cooperative path costs $97 (filing fee) plus postage. The uncooperative-spouse path adds sheriff service ($50–$62) or a private process server ($50–$75). If your spouse can't be found, publication adds $100–$250. These costs can be waived if the court approves your indigency petition (UJS-022).

Even at the high end — $97 filing + $250 publication — the total self-represented cost is well under $400. That compares to $2,000–$5,000 for an attorney-handled uncontested divorce and $10,000–$50,000+ for a contested case with full representation.

Frequently Asked Questions

Can my spouse stop me from getting divorced by refusing to sign anything?

No. In South Dakota, your spouse cannot prevent a divorce by refusing to participate. If they ignore the Admission of Service, you serve them through a sheriff or process server. If they ignore the served papers, you proceed through default judgment. A formal Answer that contests the divorce terms can make the case contested; if the Answer objects to the no-fault grounds, you may need to negotiate consent or pursue a fault-based ground.

How long does a South Dakota default divorce take?

From the date of personal service, the 30-day Answer window and the 60-day mandatory waiting period run concurrently; the day of service is not counted. The earliest you can file for default judgment is after 60 days have elapsed from service. Hearing scheduling adds time, so typical default timelines are about 60–75 days from service.

Do I have to go to court for a default divorce in South Dakota?

Yes. Unlike a stipulated divorce where both parties can finalize entirely on paperwork, a default divorce requires the plaintiff to attend a brief hearing. The hearing is typically 10–15 minutes, and you'll testify about your residency, the marriage, and the terms you're asking the court to approve.

What if my spouse is in the military?

The Servicemembers Civil Relief Act protects active-duty military members from default judgments. Before proceeding with default, you must verify your spouse's military status through the Department of Defense database and file a Statement of Military Status (UJS-306). If your spouse is on active duty and the SCRA's conditions are met, the court must appoint an attorney before entering default judgment and must grant a stay of at least 90 days.

Can I get child support through a default divorce?

Yes. If you have children and your spouse doesn't respond, you can request child support in your proposed default decree. The court will review your child support calculation worksheet and, if the amount follows the state guidelines, typically approve it. The judge may adjust the amount at the hearing if the documentation is insufficient.
