Jefferson County, Kentucky Child
Support Estimator

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

Jefferson County ranks 1st by population among 120 Kentucky 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.

Jefferson County's larger population can mean higher case volume, more specialized family-law practitioners, and more formal local procedures for child support hearings.

Jefferson County District Court is located at 600 W Jefferson St, Louisville KY 40202. The clerk can be reached at (502) 595-4481.

Check the court website for current child support forms, hearing procedures, and filing instructions. Electronic filing may be available for eligible family-law filings.

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. Kentucky's calculator model is Income Shares.

Governing authority: Ky. Rev.

Stat. § 403.212.

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 KRS § 403.212 using both parents' combined monthly adjusted gross income and the Kentucky Child Support Guidelines Table (revised 2022).

The table covers combined monthly adjusted gross income up to $15,000; above that, the court awards support in its discretion. Adjusted gross income deducts pre-existing child support orders, alimony paid to the other parent, and mandatory union dues.

Parenting time adjustment: a credit applies when the non-custodial parent exercises 40%+ of overnight time. Child care and health insurance costs are added proportionally.

Minimum support order: $60/month. Administered by the Kentucky Child Support Division within the Cabinet for Health and Family Services (CHFS) at chfs.ky.gov/childsupport.

Statute: KRS §§ 403.211–403.213.

Run the calculator with monthly or weekly income figures that match the official Kentucky 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 Jefferson 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 Kentucky 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, Kentucky 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 Jefferson 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 Kentucky Custody Time Calculator to model overnights, then compare support with the Kentucky Alimony Calculator and Kentucky Divorce Cost Estimator.
