Types of Custody in South Dakota
South Dakota recognizes several types of custody arrangements:
| Type | Description |
|---|---|
| Legal Custody | The right to make major decisions about the child’s education, healthcare, and religious upbringing. |
| Physical Custody | Where the child primarily lives on a day-to-day basis. |
| Joint Custody | Both parents share legal custody, physical custody, or both. |
| Sole Custody | One parent has exclusive legal or physical custody. |
Joint custody presumption: NO. South Dakota has no statutory presumption favoring joint custody — neither joint legal nor joint physical custody is presumed. However, if either parent requests joint physical custody, the court must consider granting it under SDCL § 25-4A-24 by evaluating a list of 17 enumerated factors. A parent’s opposition to joint physical custody is not determinative in itself, but only one factor for the court to consider. The court’s determination is based on the best interests of the child standard, not a default presumption.
South Dakota Best Interest of the Child Standard
The best interests of the child standard is the primary framework South Dakota courts use for all custody decisions. This standard considers what arrangement will best serve the child’s physical, emotional, and developmental needs.
South Dakota courts evaluate these best interest factors when making custody decisions:
- South Dakota courts determine custody based on the child’s “temporal
- mental
- and moral welfare” under SDCL § 25-4-45. The court evaluates: (1) The capacity and disposition of each parent to provide the child with protection
- food
- clothing
- medical care
- and other basic needs; (2) The ability of each parent to give the child love
- affection
- guidance
- education
- and religious upbringing (if applicable); (3) The willingness of each parent to maturely encourage and provide frequent
- meaningful contact with the other parent; (4) The commitment of each parent to prepare the child for responsible adulthood while also providing a fulfilling childhood; (5) The ability of each parent to model good parenting
- being a loving spouse
- and responsible citizenship. For contested joint physical custody requests
- SDCL § 25-4A-24 adds 17 specific factors: (1) Whether each parent is a suitable physical custodian; (2) Whether each parent has appropriate dwelling; (3) Whether the child’s psychological/emotional needs will suffer without active contact with both parents; (4) Whether one parent denied the child continuing contact with the other parent without just cause; (5) Whether parents can show mutual respect and effectively communicate regarding the child’s needs; (6) The extent to which both parents actively care for the child; (7) Whether each parent can support the other parent’s relationship with the child (including assessment of parental conflict); (8) Whether the arrangement accords with the child’s wishes or the child has strong opposition; (9) Whether a parent has intentionally alienated or interfered with the other parent’s relationship; (10) Whether one or both parents oppose joint physical custody; (11) [Reserved/renumbered]; (12) Whether the safety of the child
- other children
- or the other parent will be jeopardized; (13) Whether a parent allows a registered sex offender unsupervised access to the child; (14) Whether a parent has falsely alleged abuse to influence the custody determination (per § 25-4-45.8); (15) Whether a parent is physically and mentally capable of providing temporal
- mental
- and moral wellness; (16) Whether a parent has the capacity to provide protection
- food
- clothing
- medical care; (17) Whether a parent is willing and capable to provide love
- affection
- guidance
- and education.
Child’s preference: In South Dakota, a child’s custody preference may be considered when the child reaches No specific age. Under SDCL § 25-4-45, “if the child is of a sufficient age to form an intelligent preference, the court may consider that preference in determining the question.” The statute does not set a minimum age threshold — judges evaluate each child’s individual age and maturity. In practice, courts generally give more weight to preferences of children aged 12 and older, though younger children who demonstrate sufficient maturity may also have their preferences considered.. The weight given to the child’s preference increases with age and maturity. The court considers the child’s reasoning and whether the preference is influenced by a parent.
South Dakota Parenting Plans
South Dakota requires parents to submit a parenting plan as part of custody proceedings. A South Dakota parenting plan must include at minimum: (1) A statement declaring the type of custody the parents shall have (sole or joint, legal and physical); (2) A designation of the child’s primary residence; (3) A detailed child visitation/parenting time schedule specifying regular time, holidays, and vacations with each parent; (4) A statement delegating parental rights, responsibilities, and decision-making authority (education, healthcare, religious upbringing); (5) A method for revising the parenting plan in the future; (6) A method for dispute resolution. For shared parenting arrangements (180+ nights with each parent), the plan must also address how duties, responsibilities, and expenses are shared in proportion to incomes.
Key elements of an effective parenting plan:
- Regular residential schedule (weekdays, weekends, overnights)
- Holiday and school vacation rotation
- Transportation arrangements and pickup/drop-off logistics
- Decision-making authority (education, healthcare, extracurriculars)
- Communication methods between parents and between parent and child
- Dispute resolution process (mediation before court)
- Right of first refusal when a parent is unavailable
South Dakota Custody Relocation Rules
Under SDCL § 25-5A-29.1, a custodial parent must provide written notice of any intended relocation if the move is more than 50 miles from the other parent or out of state. Notice must be sent by certified mail or admission of service to the other legal parent at least 45 days before the intended move. The notice must state: (1) Where the parent will be relocating; (2) Why the relocation is in the best interest of the child; (3) A proposed visitation plan for the other parent. The noncustodial parent may object by filing a formal objection with the court within 30 days of receiving the notice. If no objection is filed within 30 days, the custodial parent may proceed. Exceptions to the notice requirement exist if: the move brings the child closer to the other parent; the move is within the child’s current school district; there is a valid restraining order protecting the parent or child from the noncustodial parent; or the noncustodial parent has been convicted within the last 12 months of violating a restraining order, criminal assault, child abuse, or another domestic violence crime.

Notice requirement: The relocating parent must provide 45 days advance written notice required (by certified mail or admission of service). The noncustodial parent then has 30 days from receipt to file a formal objection with the court. days advance written notice to the other parent.
The court evaluates whether the move serves the child’s best interests, considering the reason for the move, the impact on the child’s relationship with the non-moving parent, and whether a modified visitation schedule can preserve that relationship.
Modifying South Dakota Custody Orders
South Dakota uses a “substantial change in circumstances” standard for modifying contested custody orders. The parent seeking modification bears the burden of proof and must demonstrate: (1) A substantial/significant change in circumstances since the last custody order was issued; and (2) That the proposed modification is in the best interests of the child. Examples of qualifying changes include a parent’s relocation, change in the child’s needs, or safety concerns. However, if the existing custody arrangement was based on the parents’ earlier agreement (not contested), a parent seeking modification does not necessarily need to prove a substantial change in circumstances — but must still show the new arrangement is necessary for the child’s best interests and welfare (SDCL § 25-4-45).
Common modification triggers: parent relocation, change in child’s needs, substance abuse, domestic violence, parent’s work schedule change, child reaching an age where preferences are considered, or one parent consistently violating the existing order.
Special Circumstances in South Dakota Custody
Domestic violence: Under SDCL § 25-4A-22 (and cross-referenced in § 25-4-45.5), if a parent has a conviction or established history of domestic abuse, or a conviction of causing the death of the other parent, there is a rebuttable presumption that awarding custody to the abusive parent is NOT in the best interest of the child. The abusive parent bears the burden of overcoming this presumption with evidence. A history of domestic abuse may be proven by “greater convincing force of the evidence” (a clear and convincing standard). The court may also require an abusive parent to successfully complete appropriate counseling before being permitted unsupervised parenting time. When domestic abuse is established and a continuing danger exists, all parenting time with the abusive parent must cease or be allowed only under supervision, depending on the circumstances.
Grandparent visitation: YES. Under SDCL § 25-4-52, a circuit court may grant grandparents (including great-grandparents) reasonable visitation rights with their grandchild, with or without petition by the grandparents, if: (1) The visitation is in the best interests of the grandchild; AND either (a) the visitation will not significantly interfere with the parent-child relationship, OR (b) the parent or custodian has denied or prevented the grandparent reasonable opportunity to visit the grandchild. Courts must also consider the reasons behind a parent’s objections to grandparent visitation. Under SDCL § 25-4-54, these visitation rights do not apply if the child has been placed for adoption with a person other than the child’s stepparent or grandparent. The South Dakota Supreme Court has upheld this statute as constitutional.
Unmarried parents: Under SDCL § 25-5-10, when a child is born to unmarried parents, the mother is presumed to have sole custody until paternity is legally established. The father’s name on the birth certificate alone does NOT establish paternity in South Dakota. Paternity can be established in two ways: (1) Voluntarily — both parents sign a paternity affidavit under oath, which can be done at the hospital/clinic at birth or later at the South Dakota Department of Social Services, Department of Health, or local Register of Deeds Office; (2) Involuntarily — either parent may initiate administrative or legal proceedings to establish paternity, which usually includes genetic (DNA) testing. Once paternity is established, the father has equal rights to seek custody. Courts apply the same best interest standard to custody determinations for children of unmarried parents as for children of divorcing parents. Mothers and fathers are equally entitled to seek and be awarded custody regardless of marital status. The South Dakota Parenting Guidelines (UJS Form 302) apply equally to paternity actions and divorce custody cases.
Guardian ad litem: YES. Under SDCL § 25-4-45.4, the court may appoint counsel for any child involved in any divorce or custody proceeding, particularly when the child is alleged to be neglected or abused. The court allocates the cost of the appointed counsel between the parents, guardian, or custodian of the child. The guardian ad litem or appointed attorney advocates for the best interests of the child, conducting investigations and making recommendations to the court. Appointment is at the court’s discretion and is most commonly ordered in high-conflict cases or cases involving allegations of abuse or neglect.
Additional South Dakota rules: (1) South Dakota has statewide Parenting Guidelines (UJS Form 302, revised October 2021) that automatically become a court order once custody papers are served, unless parents submit their own agreed plan (SDCL § 25-4A-9) — this automatic-default-order mechanism is relatively unique among states. (2) South Dakota has a mandatory 60-day waiting period for all divorce proceedings under SDCL § 25-4-34. (3) Shared parenting threshold: 180 nights per calendar year with each parent qualifies as shared parenting, which affects child support calculations (cross-credit based on nights). (4) Parental alienation is a specifically enumerated statutory factor — SDCL § 25-4A-24(9) explicitly addresses whether a parent has “intentionally alienated or interfered with the other parent’s relationship with the child.” (5) False abuse allegations factor — SDCL § 25-4-45.8 and § 25-4A-24(14) specifically penalize a parent who falsely alleges abuse to influence custody. (6) Sex offender access factor — § 25-4A-24(13) specifically addresses a parent allowing a registered sex offender access to the child. (7) South Dakota does not have a statutory presumption of equal (50/50) shared parenting despite legislative attempts to introduce one.
