Court System Overview
Circuit Court
South Dakota handles child custody, visitation, and support matters through the Circuit Court system. The state is divided into seven judicial circuits, each with one or more circuit court judges who hear family law cases. Custody and visitation disputes are governed primarily by SDCL Chapter 25-4A (Uniform Child Custody Jurisdiction) and SDCL Chapter 25-5 (Parent and Child). Divorce proceedings that include custody determinations are filed under SDCL Chapter 25-4. South Dakota does not have a separate family court division; circuit court judges handle the full range of civil matters, including domestic relations cases.
Legal Custody
Legal custody in South Dakota refers to the right and responsibility to make major decisions concerning the child's upbringing, including education, healthcare, and religious training. Courts may award joint legal custody, where both parents share decision-making authority, or sole legal custody, where one parent has exclusive authority to make major decisions. Under SDCL 25-5-7.1, the court considers the best interests of the child when allocating legal custody.
Physical Custody
Physical custody determines where the child resides on a day-to-day basis. Courts may award sole physical custody to one parent, with the other parent receiving visitation rights, or joint physical custody where the child spends substantial time with both parents. South Dakota law does not mandate a specific schedule for joint physical custody, and the court tailors arrangements to the child's best interests under SDCL 25-5-7.1.
Presumption
South Dakota does not have a statutory presumption in favor of joint or sole custody. The court must determine custody based on the best interests of the child, without preference for either parent based on gender. Under SDCL 25-5-7.1, the court considers all relevant factors, and either parent may be awarded any form of custody. There is no presumption that joint custody is in the child's best interests, nor is there a presumption against it.
Best Interest Factors
SDCL 25-4A-609 and SDCL 25-5-7.1
The court evaluates the following factors when determining custody arrangements. Each factor represents an area where documented evidence can make a difference.
- 1 The quality of the child's relationship with each parent and the capacity of each parent to provide for the child's emotional, physical, and developmental needs (SDCL 25-4A-609)
- 2 The wishes of the child, considering the child's age and maturity sufficient to express a reasonable preference
- 3 The stability of each proposed living arrangement and the desirability of maintaining continuity in the child's environment
- 4 The mental and physical health of all individuals involved, including any history of substance abuse
- 5 The willingness and ability of each parent to facilitate and encourage a close and continuing relationship between the child and the other parent
- 6 Any history of domestic violence, abuse, or neglect by either parent, as defined under SDCL 25-10
- 7 The proximity of the parents' homes and the practical considerations of the proposed parenting schedule
- 8 Each parent's past performance of parenting responsibilities, including involvement in the child's education, healthcare, and daily routines
Note: South Dakota courts apply the best interests of the child standard without a rigid statutory checklist. The factors considered are drawn from SDCL 25-4A-609 and case law, including Fuerstenberg v. Fuerstenberg and similar decisions. The court has broad discretion to weigh any factor it deems relevant. Domestic violence findings are given serious weight, and a parent's history of abuse can substantially affect custody outcomes. The court may also appoint a guardian ad litem to investigate and make recommendations regarding the child's best interests.
Every factor above is something you can document.
Evidexi helps you track evidence for each factor your court considers.
Documentation the Court Expects
South Dakota courts expect organized, factual evidence directly tied to the best interest factors. Financial affidavits are required in cases involving child support calculations under SDCL 25-7-6.2. Parents should maintain detailed records of their involvement in the child's daily care, education, and medical needs. Documentation of domestic violence or substance abuse, if applicable, should include police reports, medical records, and protective order filings.

Filing Process
Step by Step
- 1 Determine jurisdiction: the custody action should be filed in the Circuit Court of the county where the child has resided for at least six consecutive months under the UCCJEA (SDCL 25-4A-201)
- 2 Obtain the required forms from the South Dakota Unified Judicial System website or the circuit court clerk's office in your county
- 3 Complete the Complaint for Custody (or, if filing as part of a divorce, the Complaint for Divorce including custody provisions) and the UCCJEA Affidavit disclosing the child's addresses and prior custody proceedings
- 4 File the complaint with the Clerk of Courts and pay the applicable filing fee; if you cannot afford the fee, file a Petition to Proceed In Forma Pauperis requesting a fee waiver
- 5 Serve the other parent with a copy of the complaint and summons through personal service by the county sheriff, a private process server, or as otherwise permitted under SDCL 15-6-4
- 6 The respondent has 30 days after service to file an answer or response
- 7 Attend any court-ordered mediation, settlement conference, or pretrial hearing as scheduled by the court
- 8 If the case is not resolved by agreement, attend the custody trial where both parties present testimony and evidence; the judge will issue a custody order based on the best interests of the child
Required Forms
Typical Timeline
Uncontested custody cases where both parties agree on a parenting arrangement may be resolved in 2 to 4 months. Contested cases typically take 6 to 12 months or longer, depending on the circuit, the complexity of the issues, and whether custody evaluations or guardian ad litem investigations are ordered. Temporary custody orders can be obtained on an expedited basis if immediate relief is needed.
Self-Represented (Pro Se) Notes
South Dakota allows self-representation in custody cases. The South Dakota Unified Judicial System (UJS) website at ujs.sd.gov provides forms, filing instructions, and procedural guides. Court clerks can provide forms and general procedural information but cannot give legal advice. Pro se litigants are held to the same rules and deadlines as attorneys. East River Legal Services and Dakota Plains Legal Services offer free legal assistance to qualifying individuals.

Modifying a Custody Order
What Counts as a Material Change
To modify a custody order in South Dakota, the parent seeking modification must demonstrate a substantial and material change in circumstances that has occurred since the entry of the existing order. The change must affect the child's welfare and must not have been contemplated at the time of the original order. Common grounds include a parent's relocation, significant changes in a parent's living situation, substance abuse, domestic violence, or material changes in the child's needs.
How to File for Modification
File a Motion to Modify Custody in the circuit court that issued the original order or in the court with current jurisdiction under the UCCJEA. The other parent must be properly served with the motion. The court first determines whether a substantial change in circumstances has occurred. If the threshold is met, the court conducts a full best interest analysis. The court may order mediation before scheduling a hearing on the modification.
Building Your Case Over Time
Document the specific changes in circumstances that have occurred since the last order was entered. Provide evidence such as school records, medical records, police reports, communication logs, and declarations from witnesses with direct knowledge. Evidence should clearly demonstrate how the current arrangement no longer serves the child's best interests and why the proposed modification is necessary.
Modifications require a documented trail of change.

Key Deadlines & Tips
Deadlines to Know

- The respondent has 30 days after service of the complaint to file an answer under the South Dakota Rules of Civil Procedure

Practice Tips for South Dakota
South Dakota courts value stability and continuity for children. If you are the primary caregiver, document your consistent involvement in the child's daily routines, school activities, and healthcare.
Keep detailed, organized records of all parenting exchanges, including dates, times, and any issues that arise. Timestamped documentation is persuasive in South Dakota custody hearings.
If domestic violence is a factor, obtain a protection order under SDCL 25-10 and provide thorough documentation to the court. A history of domestic abuse is given significant weight in custody determinations.
South Dakota does not require mandatory mediation in all custody cases, but many circuits strongly encourage it. Approaching mediation in good faith and with a reasonable proposed parenting plan can lead to faster, less adversarial outcomes.
Be prepared to demonstrate your willingness to support the child's relationship with the other parent. Courts closely evaluate each parent's ability to foster cooperation and shared parenting.
