Residency requirement:
At least one spouse must have been a resident of Kentucky for a minimum of 180 days (approximately six months) immediately before filing for divorce (KRS §403.140). Military members stationed in Kentucky on active duty also satisfy this requirement. You must file in the county where either spouse currently resides.
Filing fee:
$113–$250
Waiting period:
Kentucky uses the Income Shares Model to calculate child support under KRS §403.212. Both parents' gross incomes are combined and applied to a statutory child support table based on the number of children. The total obligation is then divided proportionally based on each parent's share of the combined income, with adjustments for health insurance, childcare costs, and parenting time credits under KRS §403.2121.

Kentucky parents can modify child support orders when a material change in circumstances results in at least a 10% difference in the calculated support amount under KRS 403.213. The modification threshold decreased from 15% to 10% effective July 1, 2025, making child support modification in Kentucky more accessible for families experiencing income changes, job loss, or shifts in custody arrangements. Filing a motion to modify costs $40 to $80 depending on the county, and parents can also request a free administrative review through the Kentucky Child Support Enforcement office every three years.

Understanding Child Support Modification in Kentucky

Child support modification in Kentucky requires proving a material change in circumstances that is both substantial and continuing under KRS 403.213. Kentucky courts presume a material change exists when the recalculated support amount differs by at least 10% from the current court order. This 10% threshold applies to both increases and decreases in child support, meaning either parent can file for modification when circumstances change significantly.

Kentucky uses the Income Shares Model under KRS 403.212 to calculate child support obligations. Both parents' gross monthly incomes are combined and applied to a statutory table based on the number of children. The total obligation is divided proportionally based on each parent's share of combined income. Kentucky's statutory table covers combined adjusted gross incomes from $650 to $30,000 per month, with the upper limit increased from $15,000 effective July 1, 2025.

The Kentucky Legislature enacted significant changes to child support laws effective July 1, 2025. The modification threshold dropped from 15% to 10%, making it easier for parents to adjust support when circumstances change. The maximum combined income covered by guidelines doubled from $15,000 to $30,000 per month. These changes affect all new modification requests filed after July 1, 2025, and reflect Kentucky's commitment to modernizing child support calculations.

Grounds for Modifying Child Support in Kentucky

Kentucky courts grant child support modifications when parents demonstrate a substantial and continuing change in circumstances under KRS 403.213. The change must result in at least a 10% difference between the current order and the recalculated guideline amount. Courts evaluate each modification request based on documented evidence of changed circumstances.

Income Changes That Qualify for Modification

Job loss constitutes a material change in circumstances under Kentucky law. Parents who lose employment involuntarily should file a Motion to Modify Child Support immediately after termination and provide documentation proving the job loss was not voluntary. Courts may impute income to parents who voluntarily quit jobs or reduce hours to avoid support obligations.

Significant salary increases or decreases can trigger modification eligibility. A parent receiving a 25% pay raise or experiencing a 30% income reduction would likely meet the 10% threshold for modifying the support amount. Self-employed parents must document income changes through profit-and-loss statements, tax returns, and bank records.

Disability or serious illness affecting earning capacity qualifies as a substantial change. Parents must provide medical documentation establishing the condition, its expected duration, and its impact on their ability to work. Social Security Disability benefits replace earned income in the child support calculation.

Changes in the Child's Circumstances

Increased medical expenses not covered by insurance can justify modification. If a child develops a chronic condition requiring $500 per month in out-of-pocket costs, either parent can request modification to address these additional expenses. Courts consider both recurring medical costs and one-time major expenses.

Educational needs may warrant support adjustments. Private school tuition, special education services, or learning disability accommodations can constitute changed circumstances. Kentucky courts evaluate whether additional educational expenses are reasonable and necessary for the child's development.

Changes in custody or parenting time arrangements affect child support calculations. If parenting time shifts from 80/20 to 60/40, the support obligation changes under Kentucky's shared parenting adjustment formula. Parents with at least 88 overnights per year qualify for a parenting time credit ranging from 15% to 50% of the base obligation.

Other Qualifying Changes

Remarkriage of either parent does not automatically justify modification. However, a new spouse's income may affect the parent's ability to pay or need for support indirectly. Courts cannot directly include step-parent income in child support calculations but may consider household expenses.

Birth of additional children to either parent can constitute a material change. Kentucky courts balance obligations to all children, though existing support orders for prior children receive priority. The paying parent must document support obligations to subsequent children.

Emancipation of one child in a multi-child order triggers automatic recalculation. When a child turns 18 (or 19 if still in high school), the support amount must be adjusted for the remaining children. Parents should file for modification rather than simply reducing payments.

How to File for Child Support Modification in Kentucky

Filing for child support modification in Kentucky requires submitting a Motion to Modify Child Support to the Circuit Court in the county where the original order was entered. The process involves gathering documentation, completing court forms, paying filing fees, serving the other parent, and attending a court hearing. Most modification cases resolve within 60 to 90 days from filing.

Step 1: Gather Required Documentation

Parents requesting modification must compile comprehensive financial documentation. Required documents include the last three months of pay stubs, the two most recent federal tax returns with all schedules, W-2 forms, bank statements showing current balances, and proof of any other income sources. Self-employed parents need profit-and-loss statements, business tax returns, and 1099 forms.

Document the specific change in circumstances that justifies modification. For job loss, obtain termination letters, unemployment benefit statements, and evidence of job search efforts. For medical changes, gather doctor's statements, diagnosis documentation, and itemized medical bills. For custody changes, collect calendars showing actual parenting time and any informal agreements about schedule modifications.

Step 2: Complete Court Forms

Kentucky requires specific forms for child support modification. Form AOC-795 (Petition for Relief, Modification or Termination) serves as the primary motion document. Parents must also complete a current Child Support Worksheet using the Kentucky child support guidelines under KRS 403.212 and a Financial Disclosure Form documenting all income and expenses.

Download forms from the Kentucky Court of Justice website at kycourts.gov or obtain copies from your local Circuit Court Clerk's office. Complete all forms accurately and legibly. Include only the last four digits of Social Security numbers and financial account numbers for privacy protection.

Step 3: File the Motion and Pay Fees

File your completed motion with the Circuit Court Clerk in the county where the original child support order was entered. The filing fee ranges from $40 to $80 depending on the county. As of March 2026, verify the exact amount with your local clerk before filing.

Kentucky offers fee waivers through Form AOC-205 for parents who cannot afford filing costs. Individuals earning less than $30,120 annually or couples earning less than $40,880 (below 200% of federal poverty guidelines) may qualify. Parents receiving SNAP, Medicaid, or SSI benefits typically qualify automatically for fee waivers.

Electronic filing is available through KYeCourts, the Kentucky Court of Justice's online filing system. Create a user account to file electronically and receive case updates. Alternatively, file conventional paper documents at the clerk's window during business hours.

Step 4: Serve the Other Parent

After filing, you must serve the other parent with notice of the modification motion. Kentucky requires service at least 10 days before any scheduled hearing date. Service methods include personal service by the sheriff or a private process server, certified mail with return receipt requested, or acceptance of service signed by the other parent.

Obtain proof of service documentation and file it with the court. The case cannot proceed without proper service. If you cannot locate the other parent, Kentucky allows service by publication in a newspaper of general circulation, though this process adds several weeks to the timeline.

Step 5: Attend the Hearing

The court schedules a hearing where both parents present evidence supporting their positions. Bring original copies of all documentation, including pay stubs, tax returns, and medical records. Prepare a clear explanation of how circumstances have changed and how those changes affect the child support calculation.

Judges evaluate whether the evidence supports a material change in circumstances under KRS 403.213. If the recalculated amount differs by at least 10% from the current order, courts typically grant modification. The judge issues a new child support order reflecting the modified amount, which takes effect from the date of filing or the date of the hearing, depending on the court's decision.

Free Administrative Review Option

Kentucky Child Support Enforcement conducts administrative reviews of child support orders every three years upon request from either parent. These reviews compare existing orders to current guideline calculations and recommend modification if the threshold is met. The review process is free and does not require court filing or attorney fees.

How to Request an Administrative Review

Contact your assigned Child Support Enforcement caseworker in the regional office enforcing your order. Submit a written request identifying yourself, stating specifically what circumstances have changed, and requesting a case review. Include documentation supporting your request, such as pay stubs, tax returns, or proof of changed custody arrangements.

The Child Support Enforcement office, now under the Kentucky Office of Attorney General as of July 1, 2025, processes review requests and calculates updated support amounts using current guidelines. If the recalculated amount differs by at least 10% from the existing order, the office initiates modification proceedings.

When to Use Administrative Review vs. Court Filing

Administrative review works best for straightforward modifications based on routine income changes. The process is free and does not require navigating court procedures. However, administrative review takes longer than direct court filing and may not address complex issues like disputed income or custody changes.

Direct court filing provides faster resolution for urgent situations like job loss or medical emergencies. Courts can issue temporary orders during modification proceedings, while administrative review cannot. Parents facing significant arrearages or enforcement issues should file directly with the court for comprehensive relief.

Timeline and What to Expect

Child support modification cases in Kentucky typically resolve within 60 to 90 days from filing to final order. The timeline varies based on court schedules, service of process challenges, and whether the modification is contested. Uncontested modifications where both parents agree can finalize in as few as 30 days.

StageTypical Timeline
Document gathering1-2 weeks
Filing and service1-3 weeks
Waiting for hearing date4-8 weeks
Hearing and orderSame day to 2 weeks
Total (contested)60-90 days
Total (uncontested)30-45 days

Temporary Orders During Modification

Parents experiencing emergency circumstances can request temporary modification orders while the full case proceeds. Courts may grant temporary relief for situations like sudden job loss, medical emergencies, or domestic violence. Temporary orders remain in effect until the final modification hearing.

Continue paying the current court-ordered amount until the court modifies the order. Unilaterally reducing payments creates arrearages that remain enforceable even after modification. Kentucky courts cannot retroactively forgive unpaid support, and arrearages accrue interest at 12% per year.

Effective Date of Modified Orders

Kentucky courts have discretion regarding when modified support amounts take effect. Modifications typically become effective on the date of filing the motion or the date of the hearing. Courts may backdate modifications to the filing date when the requesting parent demonstrates prompt action after circumstances changed.

New support amounts apply only to future payments. Courts cannot modify support for periods before the modification request was filed. This rule underscores the importance of filing promptly when circumstances change rather than waiting to accumulate arrearages or overpayments.

Costs Associated with Modification

The total cost of child support modification in Kentucky varies based on whether you hire an attorney and whether the modification is contested. Self-represented parents can complete simple modifications for $40 to $80 in filing fees. Contested modifications requiring attorney representation typically cost $1,500 to $5,000 in legal fees.

Cost CategoryAmount
Filing fee$40-$80
Service of process$25-$75
Attorney fees (simple modification)$500-$1,500
Attorney fees (contested)$1,500-$5,000
Court reporter (if requested)$100-$300
Expert witnesses (if needed)$500-$2,000

Fee Waiver Eligibility

Low-income parents can request filing fee waivers using Form AOC-205. Kentucky grants waivers for individuals earning below 200% of federal poverty guidelines. For 2026, single individuals earning less than $30,120 annually and couples earning less than $40,880 qualify. Recipients of SNAP, Medicaid, SSI, or TANF benefits qualify automatically upon showing proof of benefits.

When to Hire an Attorney

Consider hiring an attorney for contested modifications where the other parent disputes the change in circumstances. Attorneys provide value when cases involve disputed income (especially self-employment), allegations of hidden income or underemployment, complex custody arrangements, or high combined incomes above the guideline table.

Self-representation works well for uncontested modifications where both parents agree on the new amount. Kentucky courts provide self-help resources, and the forms are designed for completion without legal training. The Child Support Enforcement office can assist with calculations and paperwork.

Common Mistakes to Avoid

Parents seeking child support modification in Kentucky should avoid several common errors that delay resolution or result in denied petitions. Understanding these pitfalls helps ensure successful modification outcomes.

Stopping Payments Before Modification

Never reduce or stop child support payments without a court order. Arrearages continue accumulating at the full ordered amount until the court issues a modified order. Kentucky courts enforce arrearages for up to 15 years after the child reaches majority, and unpaid support accrues 12% annual interest under KRS 403.212.

Filing Without Sufficient Evidence

Courts deny modification requests lacking adequate documentation of changed circumstances. Provide concrete evidence including pay stubs, tax returns, medical records, or custody calendars. Conclusory statements like "my income decreased" without supporting documentation fail to meet the burden of proof.

Missing Deadlines

Respond promptly to court deadlines and hearing dates. Missing a hearing can result in default judgment against you. If you cannot attend a scheduled hearing, file a motion for continuance before the hearing date and provide good cause for the delay.

Waiting Too Long to File

Delaying modification requests prolongs financial hardship and allows arrearages or overpayments to accumulate. File promptly when circumstances change significantly. Courts cannot retroactively modify support for periods before your filing date.
