South Dakota courts decide child custody based on the best interests of the child under SDCL 25-4-45 and Chapter 25-4A. The state uses standard terms: legal custody (decision-making authority) and physical custody (where the child lives). South Dakota has no presumption of joint physical custody; SDCL 25-4A-26 expressly says so.
How does South Dakota decide child custody?
South Dakota courts apply the best interests of the child standard to every custody determination. The controlling statutes are SDCL 25-4-45 and Chapter 25-4A. Circuit courts in the county where the child resides handle custody cases. Judges weigh the child's physical and emotional welfare, each parent's fitness, the stability each home provides, and any history of domestic violence or abuse. Because South Dakota general custody factors come largely from case law rather than a single enumerated list, the court has broad discretion to consider everything relevant to the child's welfare. The goal in every case is to craft an arrangement that serves the child, not the preferences of either parent.
Types of custody in South Dakota
South Dakota recognizes two types of custody: legal and physical. Legal custody is the authority to make major decisions about the child's upbringing, including choices about education, medical care, and religious instruction. Physical custody refers to where the child physically lives and the day-to-day parenting schedule.
Both types can be awarded solely to one parent or jointly between both parents. When joint legal custody is awarded, both parents share decision-making authority even if the child primarily lives with one parent. When joint physical custody is awarded, the child spends substantial time in both homes. Sole physical custody with visitation for the other parent remains a common outcome when parents live far apart or have a history of conflict that makes frequent exchanges difficult.
Does South Dakota presume joint or 50/50 custody?
South Dakota does NOT presume joint physical custody. SDCL 25-4A-26 explicitly states that no presumption of joint physical custody exists. This means neither parent starts with a legal advantage simply by asking for 50/50 time.
When a parent requests joint physical custody, the court must consider the request seriously and evaluate the statutory factors in SDCL 25-4A-24. However, the burden falls on the requesting parent to demonstrate that joint physical custody serves the child's best interests given the specific circumstances of the family. A 50/50 schedule is an available outcome, but it is not the starting point.
This is a meaningful distinction from states like Kentucky, Arkansas, or Florida, where equal parenting time is presumed. South Dakota's approach keeps the child's individual circumstances at the center of every case.
The best interests factors South Dakota courts weigh
For general custody decisions, South Dakota courts draw on case law to identify relevant factors. When a parent specifically requests joint physical custody, SDCL 25-4A-24 directs courts to consider 23 statutory factors, covering everything from each parent's suitability and ability to provide a stable home to safety, geographic proximity, and each parent's willingness to support the other parent's relationship with the child:
- Whether each parent is a suitable physical custodian for the child.
- Whether each parent has an appropriate dwelling to support physical custody.
- Whether the child's psychological and emotional development would suffer without active contact with both parents.
- Whether one parent has denied the other parent continuing contact with the child without just cause.
- Whether the parents can communicate and show mutual respect regarding the child's needs, including their general agreement on day-to-day child-rearing.
- The extent to which each parent actively cares for the child.
- Whether each parent supports the other parent's relationship with the child.
- Whether joint physical custody accords with the child's wishes, considering the child's age, maturity, and reasons for any objection.
- Whether a parent has intentionally alienated or interfered with the other parent's relationship with the child.
- Whether one or both parents oppose joint physical custody, though opposition alone is not determinative.
- The geographic proximity of the parents.
- Whether joint physical custody would jeopardize the safety of the child, other children, or the other parent.
- Whether a parent has allowed a registered sex offender custody, control, or unsupervised access to the child.
- Whether a parent has falsely alleged, or alleged without good cause, that the child or a sibling was abused or neglected.
- Whether a parent is physically and mentally capable of providing for the child's wellness.
- Whether a parent can provide the child's basic needs, including food, clothing, and medical care.
- Whether a parent is willing and able to provide love, affection, guidance, and religious or moral education.
- Whether a parent is committed to preparing the child for responsible adulthood and a fulfilling childhood.
- Whether a parent models what it means to be a good parent, spouse, and responsible citizen.
- Whether a parent provides a stable home environment, including relationships with stepparents, siblings, and extended family.
- The child's adjustment to home, school, and community.
- Whether breaking the child's closer attachment to one parent would harm the child.
- Whether a parent has engaged in misconduct that could harm the child.
These 23 factors apply in addition to the traditional best-interests factors South Dakota courts already weigh in every custody case. Several factors deal directly with domestic violence, sex-offender access, and false abuse allegations, so safety plays a central role whenever joint physical custody is contested. The court may also consider the child's reasonable preference when the child is mature enough to express one (factor 8), though no statute sets a fixed age at which the child's choice becomes controlling.
Relocation: moving with your child
South Dakota has a dedicated statutory framework for parental relocation. Under SDCL 25-4A-17 through 25-4A-19, a parent who wants to move in a way that would materially affect the custody or visitation arrangement must follow the statutory relocation procedures.
The court has authority to restrain a move that would be prejudicial to the child's welfare. If the relocating parent proceeds without following the procedures, the move can be treated as a material change in circumstances that justifies modifying the custody order. The non-relocating parent can file an objection, and the court will hold a hearing and apply the best-interests standard. Relocation over a significant distance frequently reopens custody entirely because the logistics of the existing parenting schedule may no longer be workable.
Changing a custody order (modification)
An existing South Dakota custody order can be modified only if there has been a material or significant change in circumstances since the order was entered, and if the proposed modification serves the best interests of the child. SDCL 25-4-45 gives the court ongoing authority to modify a custody order guided by the child's best interests; the material-change requirement itself comes from South Dakota case law applying that statute.
The requirement for a changed circumstance protects children from repeated, destabilizing litigation. Minor disputes or normal changes in a child's routine generally do not meet the threshold. Courts look for meaningful changes such as a parent's remarriage, relocation, a serious deterioration in one parent's ability to care for the child, or demonstrated endangerment. Once a material change is established, the court conducts a full best-interests analysis before entering a new order.
South Dakota's child support calculations are linked to the parenting-time schedule, so a custody modification often affects support obligations as well. See South Dakota's child support laws for details: South Dakota Child Support Laws.
If you are facing a custody case in South Dakota
If you are entering or responding to a custody action in South Dakota, several practical steps can strengthen your position:
Start by drafting a detailed proposed parenting plan that outlines a realistic physical custody schedule, a division of legal decision-making authority, and a clear process for handling disagreements. Judges appreciate parents who have thought through logistics rather than simply demanding maximum time.
Document your involvement in the child's life. School pick-ups, medical appointments, activities, and daily caregiving all go to the SDCL 25-4A-24 suitability factor. Courts want to see that each parent has an active, ongoing relationship with the child.
Keep the focus on the child's needs, not on grievances about the other parent. Disparaging the other parent in court or in front of the child reflects poorly and can cut against a joint-custody request, since the ability to communicate and respect the other parent's relationship is an explicit statutory factor.
Consider mediation before going to a full trial. South Dakota circuit courts may refer contested custody cases to mediation. Reaching a negotiated agreement gives both parents more control over the outcome than leaving the decision entirely to a judge.
For any disputed custody matter, consulting a licensed family-law attorney in South Dakota is the most important step. The best-interests standard gives courts wide discretion, and the right strategy depends heavily on the specific facts of your family.

Frequently Asked Questions
How is child custody determined in South Dakota?
South Dakota courts decide custody based on the best interests of the child. The court considers each parent's suitability, the child's adjustment to home and school, each parent's relationship with the child, any history of abuse, and the ability of the parents to cooperate. The controlling statutes are SDCL 25-4-45 and Chapter 25-4A.
Does South Dakota favor the mother in custody cases?
No. South Dakota family-law statutes are gender-neutral. Courts may not prefer a parent based on sex. The old tender-years doctrine that favored mothers has been abolished. Both parents start on equal legal footing, and the decision turns entirely on the best interests of the child.
Is South Dakota a 50/50 custody state?
No. SDCL 25-4A-26 expressly states that there is no presumption of joint physical custody in South Dakota. A court must consider a request for joint physical custody and apply the 23 statutory factors in SDCL 25-4A-24, but equal parenting time is not automatic or presumed.
At what age can a child choose which parent to live with in South Dakota?
South Dakota law does not set a fixed age at which a child's preference becomes controlling. Courts may consider the child's reasonable preference as one factor in the best-interests analysis, with more weight given to older and more mature children. A judge retains full discretion to make the final custody determination regardless of the child's stated preference.
How do I change a custody order in South Dakota?
To modify an existing custody order you must show a material or significant change in circumstances since the order was entered, a standard South Dakota case law has developed under SDCL 25-4-45's authority to modify custody, and then demonstrate that the proposed change serves the best interests of the child. Routine changes in routine generally do not qualify; examples that may qualify include relocation, remarriage, or a serious change in a parent's fitness.
Can a parent move away with the child in South Dakota?
A parent who wants to relocate in a way that would materially affect the custody arrangement must follow the statutory relocation procedures under SDCL 25-4A-17 to 25-4A-19. The other parent may object, and the court can restrain a move that would be prejudicial to the child's welfare. Moving without following these procedures can be treated as a material change in circumstances.
What is the difference between legal and physical custody in South Dakota?
Legal custody is the right to make major decisions about the child's education, healthcare, and religious upbringing. Physical custody refers to where the child lives and the day-to-day parenting schedule. Both can be sole (one parent) or joint (shared between both parents), and courts may award different arrangements for each type.

Updates
Corrected the count of SDCL 25-4A-24's joint-physical-custody factors from 5 to the statute's actual 23, added the missing factors (including safety, sex-offender-access, and false-abuse-allegation factors) across the meta description, key takeaways, body, and FAQ, and clarified that the 'material or significant change' modification standard comes from South Dakota case law applying SDCL 25-4-45 rather than the statute's own text.
