South Dakota divorcing spouses face a unique legal landscape where one wrong move can cost thousands of dollars, jeopardize custody outcomes, or trigger contempt-of-court charges. The state's automatic temporary restraining order under SDCL 25-4-33.1 activates the moment divorce papers are served, restricting both parties from transferring assets, canceling insurance, or removing children from the state. With South Dakota's all-property equitable distribution system under SDCL 25-4-44, where judges can divide premarital, inherited, and marital assets alike, understanding what not to do during divorce in South Dakota is just as important as knowing what to do.

Here are the 10 biggest divorce mistakes South Dakota residents must avoid, each grounded in specific state statutes and court procedures.
1. Never Hide, Transfer, or Dissipate Marital Assets
South Dakota's automatic temporary restraining order under SDCL 25-4-33.1 prohibits both spouses from transferring, encumbering, concealing, or dissipating any marital assets from the moment divorce papers are served until the final decree is entered. Violating the ATRO can result in contempt of court charges, financial sanctions, and an unfavorable property division outcome.
South Dakota is an all-property equitable distribution state under SDCL 25-4-44, meaning courts can divide property belonging to either or both spouses, regardless of title or when it was acquired. This includes premarital assets, inherited property, and gifts. Attempting to hide assets in this legal framework is particularly risky because courts have broad authority to trace and recover concealed property. South Dakota judges consider each spouse's contribution to the accumulation of property, the duration of the marriage, the ages and health of both parties, and each party's earning capacity when dividing assets. Spouses who attempt to move money to relatives, open secret accounts, or undervalue business interests often face penalties that far exceed whatever they tried to protect. The ATRO specifically allows only expenditures made in the usual course of business or for necessities of life.
2. Do Not Violate the Automatic Temporary Restraining Order
South Dakota's ATRO under SDCL 25-4-33.1 contains five specific prohibitions that take effect automatically upon service of the divorce summons. Both parties are restrained from making extraordinary expenditures, canceling insurance coverage, molesting or disturbing the peace of the other party, and removing minor children from South Dakota, in addition to the asset-protection provisions.
The ATRO provisions must be printed directly on the divorce summons itself, so claiming ignorance is not a viable defense. Common violations include canceling a spouse's health insurance, removing the other spouse from auto insurance policies, closing joint credit cards, and taking children on out-of-state trips without consent. Each violation can result in a contempt finding, which carries potential jail time and fines in South Dakota circuit courts. One of the most common divorce mistakes in South Dakota is failing to read and understand the ATRO restrictions printed on the summons. Either party may petition the court to modify specific ATRO provisions, but unilateral action without court approval risks severe consequences.
3. Never Use Children as Leverage in Custody Disputes
South Dakota courts determine child custody based on the best interests of the child with respect to the child's temporal, mental, and moral welfare under SDCL 25-4-45. Parents who use children as bargaining chips, attempt parental alienation, or restrict the other parent's access without court authorization consistently receive unfavorable custody outcomes.
For joint physical custody determinations under SDCL 25-4A-24, South Dakota courts evaluate five specific statutory factors: whether each parent is a suitable physical custodian, whether each parent has appropriate dwelling, whether the child's psychological development will suffer without active contact with both parents, whether one parent has denied continuing contact without just cause, and whether parents can demonstrate mutual respect and effective communication. Denying visitation, badmouthing the other parent in front of children, or coaching children to express custody preferences are among the most damaging divorce mistakes a South Dakota parent can make. Courts also consider any history of domestic violence, and South Dakota law creates a presumption against awarding custody to an abusive parent.
| Custody Factor | What Courts Evaluate | Impact of Violation |
|---|---|---|
| Parental fitness | Mental and physical health of each parent | Negative custody determination |
| Cooperation (SDCL 25-4A-24) | Willingness to facilitate contact with other parent | May lose joint custody eligibility |
| Child's preference | Child of sufficient age to form intelligent preference | Court may interview child directly |
| Domestic violence | Any past convictions or abuse history | Presumption against custody |
| Stability | Appropriate dwelling, consistent routine | Relocation triggers additional scrutiny |
4. Do Not Make Major Financial Decisions Without Legal Counsel
South Dakota's equitable distribution framework under SDCL 25-4-44 gives judges broad discretion to divide all property, making premature financial decisions one of the costliest common divorce errors. Selling real estate, cashing out retirement accounts, taking on new debt, or making large purchases during a pending divorce can dramatically alter the equitable distribution analysis.
Uncontested divorces in South Dakota typically cost between $2,000 and $5,000, while contested divorces range from $10,000 to $25,000 or more depending on complexity. The filing fee itself is only $50, making legal counsel the primary cost factor. Yet attempting to save money by making financial decisions without an attorney often costs far more in the long run. South Dakota courts consider the income-producing capacity of each party's assets, meaning that liquidating investments or retirement accounts during proceedings can permanently reduce the marital estate's value and trigger tax penalties of 10% or more for early withdrawals. The 60-day mandatory waiting period under South Dakota law provides time to consult with financial advisors and attorneys before making irreversible decisions.
5. Never Post About Your Divorce on Social Media
South Dakota courts regularly admit social media posts as evidence in divorce proceedings, and a single ill-advised Facebook, Instagram, or TikTok post can undermine custody arguments, disprove financial disclosures, or contradict sworn testimony. Posts showing expensive purchases contradict claims of financial hardship, while photos of excessive partying can affect custody determinations under SDCL 25-4-45.
Digital evidence is particularly problematic in South Dakota because of the state's all-property division model under SDCL 25-4-44. A post showing a new car, vacation, or luxury purchase during divorce proceedings gives opposing counsel evidence of undisclosed income or asset dissipation. Even deleted posts can be recovered through discovery requests. South Dakota attorneys routinely advise clients to suspend all social media activity during divorce proceedings. This extends to dating apps, which can provide evidence of adultery as a fault ground under SDCL 25-4-2(1). Understanding what not to do during divorce in South Dakota starts with recognizing that anything posted online can and likely will be presented in court.
6. Do Not Ignore Court Orders or Filing Deadlines
South Dakota circuit courts impose strict deadlines for responding to divorce petitions, filing financial disclosures, and complying with temporary orders. The respondent typically has 30 days to answer the divorce complaint after service. Failure to respond results in a default judgment, which under SDCL 25-4-17.2 allows the court to grant the divorce on irreconcilable differences without the defaulting spouse's consent.
South Dakota is one of only two states (alongside Mississippi) where a no-fault divorce cannot be granted over one spouse's active objection under SDCL 25-4-17.2. Irreconcilable differences require either mutual consent or the respondent's default. This means that ignoring court papers has an especially severe consequence in South Dakota: it effectively consents to no-fault grounds that could otherwise be contested. Beyond default judgments, failing to comply with discovery requests, court-ordered evaluations, or temporary support orders can result in contempt charges, sanctions, and adverse inferences. South Dakota courts may also award attorney fees to the complying spouse when the other party causes unnecessary delay.
7. Never Refuse to Disclose Financial Information
Full financial disclosure is mandatory in South Dakota divorce proceedings, and courts require both parties to provide complete documentation of income, assets, debts, and expenses. Hiding financial information violates the ATRO under SDCL 25-4-33.1 and can result in the court reopening the property division even after the divorce is finalized.
Because South Dakota applies all-property equitable distribution under SDCL 25-4-44, judges need a complete financial picture to make fair division determinations. This includes bank statements, tax returns (typically 3 to 5 years), business valuations, retirement account statements, real estate appraisals, and documentation of all debts. South Dakota courts consider seven primary factors when dividing property: the duration of the marriage, the value of property, the ages of the parties, their health, their competency to earn a living, each party's contribution to accumulation of property, and the income-producing capacity of each party's assets. Incomplete or inaccurate financial disclosures prevent the court from properly weighing these factors and consistently result in sanctions, adverse credibility findings, and unfavorable property awards.
8. Do Not Move Out of State with Your Children
South Dakota's ATRO under SDCL 25-4-33.1 specifically prohibits removing any minor child from the state during pending divorce proceedings without written consent from the other parent or a court order. Violating this provision is one of the most serious divorce mistakes a parent can make in South Dakota, potentially resulting in contempt charges and an immediate change in custody arrangements.
Even after the divorce is finalized, South Dakota courts retain jurisdiction over custody modifications and relocation disputes. A parent seeking to relocate with children must demonstrate that the move serves the children's best interests under SDCL 25-4-45. Courts evaluate whether the relocation would impair the non-relocating parent's ability to maintain a meaningful relationship with the children. South Dakota's 66 counties span a large geographic area, and even in-state moves of significant distance may trigger judicial review. Parents who relocate without court approval risk losing primary custody, being ordered to return the children, and bearing the full cost of the other parent's attorney fees incurred to enforce the custody order.
9. Never Agree to an Unfair Settlement Under Pressure
South Dakota's mandatory 60-day waiting period exists partly to prevent hasty decisions, yet many divorcing spouses agree to unfair settlements because they want the process to end quickly. The filing fee in South Dakota is only $50, but the financial consequences of an inequitable settlement can last decades, especially regarding retirement assets, real estate, and spousal support obligations under SDCL 25-4-41.
South Dakota courts have broad discretion to award alimony for the life of the receiving spouse or for a shorter period as deemed just under SDCL 25-4-41. The informal guideline of approximately 1 year of alimony per 3 years of marriage means that a 15-year marriage could result in 5 years of support payments. Fault in causing the divorce is a relevant factor in South Dakota alimony determinations, unlike many other states. Accepting an unfair property split to avoid an alimony obligation, or vice versa, without understanding the full financial picture is among the biggest divorce mistakes South Dakota residents make. Courts generally will not modify property division after the divorce is final, making it critical to negotiate carefully before signing any settlement agreement. Marriages under 5 years in South Dakota rarely result in alimony awards except in exceptional circumstances.
10. Do Not Represent Yourself in a Contested Divorce Without Understanding the Consequences
South Dakota offers free self-help divorce forms through the Unified Judicial System at ujs.sd.gov, and the state's $50 filing fee is among the lowest in the nation. However, pro se representation in a contested divorce involving children, significant assets, or complex property often leads to outcomes that cost far more than attorney fees would have.
South Dakota's seven fault-based grounds for divorce under SDCL 25-4-2 create strategic complexity that unrepresented parties rarely navigate effectively. The state's unique requirement that no-fault divorce on irreconcilable differences requires either mutual consent or default under SDCL 25-4-17.2 means that a contested case may require proving fault grounds such as adultery, extreme cruelty, willful desertion, willful neglect, habitual intemperance, or conviction of a felony. South Dakota's all-property division framework means that premarital assets, inheritances, and gifts are all subject to division, requiring sophisticated legal analysis. The State Bar of South Dakota offers lawyer referral services at findalawyerinsd.com, and the UJS Legal Form Help Line at 1-855-784-0004 provides guidance on procedural requirements. Fee waivers are available for indigent filers through Form UJS-022.
What Happens If You Make These Divorce Mistakes in South Dakota?
South Dakota circuit courts have broad remedial authority when a spouse violates court orders, conceals assets, or acts in bad faith during divorce proceedings. Consequences include contempt of court (carrying potential jail time and fines), adverse property division adjustments, modified custody arrangements, awards of attorney fees to the non-violating spouse, and sanctions for discovery abuse. Under the ATRO provisions of SDCL 25-4-33.1, the court may also issue additional protective orders and modify existing restraints based on either party's petition.
The financial stakes in South Dakota divorces are significant because the all-property framework under SDCL 25-4-44 means courts can reallocate virtually any asset either spouse owns. A judge who discovers hidden assets or ATRO violations may shift the property division significantly in favor of the compliant spouse. Understanding what not to do during divorce in South Dakota helps protect your legal rights, financial interests, and relationship with your children throughout the 60-day minimum waiting period and beyond.
