South Dakota Custody Schedule Examples: Alternating Weeks, 2-2-3, and More

Why the Schedule Model Matters

The custody schedule you choose shapes your child's daily life — and your child support obligation. South Dakota's 180-night threshold for joint physical custody under SDCL § 25-4A-21 also matters under the shared-parenting child support cross-credit in SDCL § 25-7-6.27. The difference between a 50/50 schedule and a 65/35 schedule isn't just about time with your child. It determines which child support formula applies.

Here are the standard schedule models used in South Dakota, with the practical tradeoffs for each.

Alternating Weeks (Week-On, Week-Off)

The child spends 7 consecutive days with one parent, then 7 with the other. Exchanges typically happen on Friday after school.

Overnight split: 182.5 nights each — well above the 180-night shared custody threshold.

Best for: School-age children in low-conflict households. The schedule is simple, predictable, and requires only one exchange per week.

Watch out for: This doesn't work for children under 5. A full week away from either parent is too long for toddlers and preschoolers who need frequent contact to maintain secure attachment. It also requires a basic level of cooperation — if one parent uses the child's week to undermine the other parent's relationship, the long stretches make that damage worse.

2-2-3 Rotation

Two days with Parent A, two days with Parent B, then a three-day weekend with Parent A. The pattern reverses the following week — so both parents get alternating weekends.

Overnight split: 182.5 nights each.

Best for: Toddlers and preschoolers (ages 2–5) who benefit from frequent contact with both parents. The child never goes more than 3 days without seeing each parent.

Watch out for: The constant transitions — three or four exchanges per week — demand highly cooperative co-parents. If exchanges are tense, this schedule puts the child in the middle of conflict several times a week. It also doesn't work well for teenagers, who find the constant back-and-forth disruptive to their social lives and homework routines.

2-2-5-5 Rotation

Parent A always has Monday and Tuesday nights. Parent B always has Wednesday and Thursday nights. The Friday-through-Sunday weekend alternates, creating consistent 5-day blocks with each parent.

Overnight split: Roughly 182 nights each.

Best for: School-age children (6–12). The fixed weekday assignments simplify school logistics — the same parent always handles Monday/Tuesday homework, the same parent always manages Wednesday/Thursday activities. Teachers know which parent to contact on which days.

Watch out for: A 5-day stretch is too long for infants and toddlers. And this schedule fails completely if parents live more than about 30 miles apart — the midweek transitions become impractical when each involves a long drive to school.

4-3 Schedule

Four consecutive days with one parent (typically Monday through Thursday), then three with the other (Friday through Sunday).

Overnight split: 156 nights for the weekend parent, 209 for the weekday parent.

Best for: Families where one parent works weekends or when the parents want to separate school-week structure from weekend flexibility. The child has a stable school-week base with one parent.

Watch out for: The weekend parent only gets 156 overnights — well below the 180-night threshold. That means this schedule doesn't qualify as joint physical custody for child support purposes. The weekday parent is treated as the primary custodian, and support is calculated under the standard formula rather than the shared parenting cross-credit.

The Default UJS-302 Schedule

If parents don't agree on a custom schedule and neither objects to the standard guidelines within 10 days, the UJS-302 default kicks in: alternating weekends (Friday 3:15 PM to Monday 8:00 AM) plus a midweek Wednesday overnight.

Overnight split: Approximately 130–140 nights for the noncustodial parent.

Best for: This serves as a floor — a minimum level of parenting time that protects the noncustodial parent's relationship with the child. It works as a starting point when one parent's work schedule limits weekday availability.

Watch out for: This schedule doesn't come close to the 180-night threshold. The noncustodial parent will pay standard child support without the shared parenting cross-credit. If you want more time, you need to propose an alternative in your parenting plan.

Infant and Toddler Modifications

South Dakota's 2026 updated parenting guidelines (effective July 1, 2026) expand overnight provisions for infants and toddlers. For infants and toddlers, shorter, more frequent visits can help maintain bonding with both parents. The guidelines extend the minimum visit length from 18 to 24 hours for specific age groups.

A step-up plan — starting with shorter, more frequent visits and gradually adding overnights as the child grows — is a common approach for very young children. For children ages 2–5, a 2-2-3 rotation can provide frequent contact. By school age, alternating weeks may become practical.

Choosing the Right Schedule

The right schedule depends on your child's age, the geographic distance between homes, each parent's work schedule, and the level of conflict between co-parents. The South Dakota Child Custody & Parenting Plan Guide includes a schedule comparison worksheet that helps you evaluate each model against your family's specific circumstances — including the overnight count and its impact on child support.
