South Dakota courts determine child custody based on the best interest of the child standard, with judges evaluating parental fitness, each parent's ability to provide for the child's physical and emotional needs, and willingness to facilitate contact with the other parent. Under SDCL § 25-5-7.1, joint legal custody means both parents retain full parental rights and must confer on major decisions affecting the child's welfare. The state's mandatory 60-day waiting period under SDCL § 25-4-34 applies to all divorce proceedings, and both parents must complete a court-approved parenting education course within 60 days of filing per Supreme Court Rule 22-09.

Types of Child Custody in South Dakota
South Dakota recognizes two distinct forms of custody: legal custody (decision-making authority) and physical custody (where the child resides). Under SDCL § 25-5-7.1, joint legal custody requires both parents to participate in major decisions affecting their children's welfare, including education, healthcare, and religious upbringing. Courts may award sole legal custody to one parent when cooperation proves impossible or when one parent demonstrates unfitness.
Physical custody determines the child's primary residence and daily care arrangements. South Dakota law does not presume that joint physical custody serves children's best interests, unlike some states. When one parent requests joint physical custody, the court must evaluate specific factors under SDCL § 25-4A-24 before making a determination. Approximately 80% of South Dakota custody cases result in one parent receiving primary physical custody with the other parent receiving parenting time.
Legal Custody Options
Sole legal custody grants one parent exclusive authority over major decisions. Joint legal custody, more common in South Dakota, requires both parents to collaborate on significant choices affecting their children. Courts favor joint legal custody when parents demonstrate the ability to communicate effectively and make decisions together, even if they cannot agree on physical custody arrangements.
Physical Custody Arrangements
Primary physical custody places the child with one parent for the majority of time, while the other parent receives scheduled parenting time. Shared physical custody divides the child's time more equally between households, though South Dakota courts do not automatically presume this arrangement benefits children. The court evaluates each family's circumstances individually.
Best Interest of the Child Standard in South Dakota
South Dakota courts apply the best interest of the child standard when making all custody determinations, though the state does not codify a specific list of factors like many other jurisdictions. Under SDCL § 25-4-45, judges have broad discretion to evaluate each family's unique circumstances. The South Dakota Supreme Court has established guiding principles that trial courts follow, focusing on parental fitness and capacity to provide for children's temporal, mental, and moral welfare.
When determining fitness, courts examine each parent's mental and physical health, capacity to provide for the child's physical and emotional needs, willingness to provide frequent and meaningful contact with the other parent, and ability to serve as a role model for responsible adulthood. A parent's history of domestic violence creates a rebuttable presumption against that parent in custody proceedings.
Factors for Joint Physical Custody Requests
When either parent requests joint physical custody, SDCL § 25-4A-24 requires courts to consider additional specific factors:
- Whether each parent is a suitable physical custodian
- Whether each parent has an appropriate dwelling
- Whether the child's psychological and emotional needs require active contact with both parents
- Whether one parent has denied the child contact with the other parent without just cause
- Whether parents can demonstrate mutual respect and effective communication
- Whether the arrangement accords with the child's wishes (considering age and maturity)
- Whether either parent has intentionally alienated the child from the other parent
- Whether either parent falsely alleged abuse to influence the custody determination
- Whether each parent can provide protection, food, clothing, medical care, and other basic needs
- Whether either parent is guilty of misconduct that may harm the child
Child's Preference in Custody Decisions
Under SDCL § 25-4-45, South Dakota courts may consider a child's custody preference if the child demonstrates sufficient age and maturity to express an intelligent preference. The statute does not specify a minimum age, leaving judges to evaluate each child's individual capacity. Generally, children aged 12 and older receive more weight for their stated preferences, though judges consider preferences of younger children who demonstrate maturity.
South Dakota Parenting Time Guidelines
The South Dakota Supreme Court established statewide parenting time guidelines that serve as the default custody arrangement when parents cannot agree on a parenting plan. Under SDCL § 25-4A-9, these guidelines become a court order once one party serves divorce or custody papers, unless parents create their own agreed-upon parenting plan. The guidelines provide age-appropriate schedules designed to maintain meaningful relationships between children and both parents.
Age-Based Parenting Time Schedules
The South Dakota Parenting Guidelines establish different schedules based on children's developmental stages:
| Age Group | Parenting Time Schedule |
|---|---|
| 0-6 months | Three 2-hour visits per week + one 6-hour weekend day |
| 6-18 months | Three 3-hour visits per week + one 6-hour weekend day |
| 18-36 months | Up to three visits per week on predictable schedule |
| 3-5 years | Transition toward overnight visits |
| 5+ years | Friday 3:15 PM to Monday 8 AM + Wednesday overnight |
For school-age children (5 and older), the standard schedule provides substantial parenting time including weekend periods from Friday afternoon through Monday morning, plus a midweek overnight on Wednesdays. Holiday schedules alternate major holidays between parents, and summer vacation typically allows for extended parenting time blocks.
Communication and Technology Provisions
The South Dakota Parenting Guidelines guarantee each parent at least three phone calls per week with the child when the child is in the other parent's care. Parents cannot take a child's cell phone away simply to deny communication with the other parent, though reasonable restrictions on cell phone use remain permissible. Both parents are entitled to usernames and passwords for all minor children's social media accounts.
Parenting Education Course Requirement
South Dakota requires all parties in custody or parenting time proceedings to complete a court-approved parenting education course within 60 days of service of the summons and complaint. This requirement became effective September 1, 2022, under Supreme Court Rule 22-09. The course must be at least four hours and cover the effects of separation or divorce on children, co-parenting skills, children's needs and coping techniques, conflict resolution options, and parental financial responsibilities.
No final decree or custody order can be entered until both parties submit certificates of completion from an approved provider. The South Dakota Unified Judicial System maintains the exclusive list of approved course providers at ujs.sd.gov. Courses from non-approved providers are not accepted. Exceptions apply for protection order proceedings and termination of parental rights cases.
Waivers and Extensions
Courts may waive or delay the parenting education requirement only for good cause. Good cause includes default by one party or completion of an approved course within the past five years. Each parent bears responsibility for arranging participation and paying course fees, which typically range from $50 to $150 depending on the provider.
Mediation Requirements in South Dakota Custody Cases
South Dakota mandates mediation in all custody disputes unless mediation is not readily available or the court determines it inappropriate under the circumstances. Under SDCL § 25-4-57, when parents cannot agree on a parenting plan, the court may order mediation before scheduling a contested custody hearing. If mediation fails, SDCL § 25-4-62 provides that the court will set a hearing and make custody and parenting time determinations.
Courts cannot order mediation in cases involving domestic violence, child abuse, substance abuse, or other circumstances making mediation inappropriate. Mediation costs are typically shared between the parties. Successful mediation allows parents to craft customized parenting plans that better suit their family's needs than standard guidelines.
Custody for Unmarried Parents in South Dakota
Under SDCL § 25-5-10, when parents are unmarried, the mother is considered the sole custodian until paternity is established and the matter is brought before the court. This legal presumption means unmarried fathers must take affirmative steps to establish their parental rights through paternity proceedings. Once paternity is established, fathers have equal rights to seek custody.
Unmarried fathers can establish paternity through voluntary acknowledgment signed by both parents at the hospital or later, or through court proceedings. South Dakota courts apply the same best interest standard to custody determinations for children of unmarried parents as they do for children of divorcing parents. Mothers and fathers are equally entitled to seek and be awarded custody regardless of marital status.
Modifying Child Custody Orders in South Dakota
Once a final custody order is in place, either parent may request modification by demonstrating a substantial change in circumstances since the original order was issued. Courts evaluate whether the changed circumstances warrant revisiting custody arrangements based on the child's best interests. The burden of proof rests with the parent seeking modification to establish that changed circumstances justify altering the existing order.
Common grounds for custody modification include relocation of a parent, significant changes in a parent's work schedule, changes in a child's needs as they age, remarriage or new household members, and evidence of parental misconduct or unfitness that emerged after the original order. Courts do not modify custody orders simply because one parent believes they could do a better job.
Relocation Notice Requirements
Under SDCL § 25-4A-17, a custodial parent must provide 45 days written notice before relocating with the children. The notice under SDCL § 25-4A-18 must include the relocating parent's proposed parenting time plan for the non-relocating parent. When both parents reside in the same community at separation and one parent later moves away, the court may impose travel costs on the relocating parent necessary to facilitate the children's continued relationship with the other parent.
Exceptions to Relocation Notice
No relocation notice is required when the move brings the child closer to the other parent, the move is within the child's current school district boundaries, a valid restraining order protects the custodial parent or child from the non-custodial parent, or the non-custodial parent has been convicted within the past 12 months of restraining order violations, criminal assault, child abuse, or domestic violence against the custodial parent or child.
Enforcement of Custody Orders
Both parents have legal obligations to follow custody and parenting time orders. A parent who fails to comply with court orders risks being found in contempt of court. Under SDCL § 25-4A-5, multiple or aggravating violations may result in custody modification. South Dakota courts take interference with parenting time seriously and may adjust custody arrangements when one parent consistently denies the other parent their court-ordered time with children.
Missed parenting time due to events beyond either parent's control, such as illness, should result in mutually agreeable makeup time arranged as quickly as feasible. Each parent must timely advise the other when a scheduled visit cannot occur. Unreasonable accumulation of missed visits may trigger enforcement proceedings or modification requests.
Costs of Child Custody Cases in South Dakota
The filing fee for divorce or custody cases in South Dakota ranges from $95 to $120 depending on the county, including a base filing fee of approximately $50, a $40 automation surcharge, and a $7 law library fee. As of March 2026, verify exact fees with your local Clerk of Courts office. Process server fees add approximately $50-$75 for personal service by the county sheriff or private process server.
Attorney Fees and Total Costs
South Dakota family law attorneys charge an average of $200-$300 per hour, with the statewide average at $252 per hour. Uncontested custody cases where parents agree on a parenting plan through mediation typically cost $2,500 to $7,500 in total attorney fees. Contested custody cases involving disputes over parenting time, allegations of abuse, or relocation issues often cost $15,000 to $20,000 or more.
Divorces involving children cost approximately 50% more than divorces without children. Survey data indicates South Dakota divorces with minor children average $16,300 in total costs, including $13,800 in attorney fees. Custody evaluations, guardian ad litem appointments, and expert witnesses can add thousands of additional dollars to contested cases.
Fee Waivers for Low-Income Parents
Parents who cannot afford filing fees may request a waiver using Form UJS-305 (Motion and Order to Waive Filing Fee and Service of Process Fee) along with a Financial Affidavit demonstrating financial hardship. The waiver covers court filing fees and service of process fees but does not cover mediation costs, parenting course fees, or attorney fees.
Domestic Violence and Custody in South Dakota
When a parent has committed domestic violence, South Dakota law creates a rebuttable presumption against reunification therapy being in the child's best interest. Courts evaluate domestic violence history as a significant factor in custody determinations, and a pattern of domestic abuse weighs heavily against awarding custody or unsupervised parenting time to the abusive parent.
Victims of domestic violence may obtain protection orders through circuit court, which can include temporary custody provisions pending formal custody proceedings. Courts cannot order mediation in cases involving domestic violence, recognizing the power imbalances that make mediation inappropriate and potentially dangerous for abuse victims.
South Dakota's Unique Residency Requirements
South Dakota has the most lenient divorce residency requirement in the United States. Under SDCL § 25-4-30, the filing party must be a South Dakota resident or active-duty military stationed in South Dakota at the time of filing, but no minimum duration of residency is required. Theoretically, a person could establish residency in South Dakota and file for divorce the same day. The filing party need not maintain South Dakota residence during the divorce proceedings to receive a final decree.
This unique residency provision makes South Dakota a destination for some individuals seeking quick divorces, though the 60-day mandatory waiting period under SDCL § 25-4-34 still applies. Custody jurisdiction typically requires the child to have resided in South Dakota for at least six months under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA).

How do I modify a custody order in South Dakota?
Custody modifications require demonstrating a substantial change in circumstances since the original order under SDCL § 25-4-45. Common grounds include parental relocation, changes in work schedules, children's evolving needs, and evidence of parental misconduct. File a motion to modify with the court that issued the original order and provide evidence supporting the requested changes.
What notice must I give before relocating with my children?
Under SDCL § 25-4A-17, custodial parents must provide 45 days written notice before relocating with children. The notice must include a proposed parenting time plan for the non-relocating parent. Exceptions apply when moving closer to the other parent, moving within the current school district, or when a protective order is in place.
Do unmarried fathers have custody rights in South Dakota?
Yes, but unmarried fathers must first establish paternity. Under SDCL § 25-5-10, mothers are presumed sole custodians until paternity is established through voluntary acknowledgment or court proceedings. Once paternity is established, fathers have equal rights to seek custody, and courts apply the same best interest standard regardless of the parents' marital status.

Violating custody orders may result in contempt of court findings. Under SDCL § 25-4A-5, multiple or aggravating violations can lead to custody modification. Document all violations and file a motion for contempt or modification with the court. Courts take parenting time interference seriously and may adjust custody arrangements when one parent consistently denies court-ordered time.
