Brookings County, South Dakota Child
Support Estimator

South Dakota child support is calculated under statewide Income Shares guidelines, but the filing, review, and enforcement process is local. Parents in Brookings County use the same statewide formula as the rest of South Dakota, then work through the county family court or child support agency process for orders, modifications, and enforcement.

Brookings County ranks 5th by population among 66 South Dakota counties. That matters for scheduling, clerk procedures, local forms, and how quickly a support order or modification moves through the court calendar.

Use this page to estimate the guideline amount first, then verify filing steps with the local court before submitting paperwork.

Brookings County's smaller local court system may have fewer family-law hearing days, so parents should confirm filing windows, remote appearance rules, and document requirements before relying on an estimate.

Brookings County Circuit Court is located at 314 6th Ave, Brookings SD 57006. The clerk can be reached at (605) 688-4200.

Check the court website for current child support forms, hearing procedures, and filing instructions.

The core inputs are each parent's income, the number of children, health insurance premiums, work-related child care, existing support obligations, and parenting time. South Dakota's calculator model is Income Shares.

Governing authority: S.D. Codified Laws § 25-7-6.2; ARSD 25:10:04.

County location does not usually change the statewide formula, but it does determine where parents file, which clerk reviews paperwork, and which local judge or hearing officer applies the guidelines. Income Shares model under SDCL § 25-7-6.2 using both parents' combined monthly net income and the South Dakota Child Support Schedule of Basic Obligations.

Combined monthly net income up to $15,000 is scheduled; above that, the court applies a formula with discretion. Net income deducts federal and state income taxes at actual withholding, FICA, Medicare, mandatory union dues, and pre-existing child support orders.

Parenting time adjustment: obligors with 180+ overnights/year (49%+) may apply for a shared-custody formula. Child care and extraordinary medical costs allocated proportionally.

Minimum support: $50/month. Administered by the South Dakota Office of Child Support Enforcement within the Department of Social Services at dss.sd.gov/childsupport.

Statute: SDCL §§ 25-7-6.1 through 25-7-6.13.

Run the calculator with monthly or weekly income figures that match the official South Dakota worksheet. If a parent is self-employed, unemployed, or paid irregularly, gather tax returns, pay stubs, and proof of benefits before relying on the estimate.

Parenting time can affect child support because many states adjust the payment when the paying parent has substantial overnights. Enter the actual schedule, not the schedule you expect to negotiate later.

Parents in Brookings County should keep a written parenting-time calendar, school schedule, holiday rotation, and transportation plan. Those documents help the court compare the calculator estimate with the real custody arrangement.

If custody is still disputed, treat the estimate as a planning number. A final South Dakota child support order can change once the court sets income findings, parenting time, insurance credits, and child care allocations.

A child support estimate is not a court order. To change an existing order, a parent usually must file a modification request and show a qualifying change in income, custody, health insurance, child care costs, or another guideline factor.

For enforcement, South Dakota may use income withholding, payment records, tax refund interception, license actions, or contempt proceedings depending on the facts and the agency or court handling the case.

Before filing in Brookings County, compare your calculator result with the current order and collect proof for each input. Courts generally need documents, not estimates alone, before changing a support obligation.

Child support often intersects with custody, alimony, property division, and divorce costs. Use the South Dakota Custody Time Calculator to model overnights, then compare support with the South Dakota Alimony Calculator and South Dakota Divorce Cost Estimator.
