Arkansas law allows either parent to petition for child support modification when a material change in circumstances occurs, specifically when either parent's gross income changes by 20% or more, or by at least $100 per month, under Ark. Code Ann. § 9-14-107. The modification process costs between $80 and $165 depending on whether you file through the Office of Child Support Enforcement (OCSE) or directly with circuit court, and typically takes 30 to 60 days for uncontested cases or 4 to 9 months for contested matters. Arkansas courts use the Income Shares Model under Administrative Order No. 10, effective July 1, 2020, which calculates support based on both parents' combined gross monthly incomes.

What Qualifies as a Material Change in Circumstances
Arkansas law defines a material change in circumstances as any 20% or greater change in either parent's gross income, or an income shift of $100 or more per month, which automatically qualifies you to petition for child support modification under Ark. Code Ann. § 9-14-107. The Arkansas Office of Child Support Enforcement must file a modification motion within 30 days of being notified of such a qualifying change. Additionally, if the difference between your current support order and the amount calculated under the current Family Support Chart constitutes a significant inconsistency, this also qualifies as grounds for modification.
Common qualifying circumstances include:
- Job loss, layoff, or significant reduction in work hours
- Substantial salary increase or promotion
- Disability that affects earning capacity
- Incarceration for 180 days or more (treated as involuntary unemployment under Act 904 of 2019)
- Significant change in the child's needs, such as medical expenses or educational costs
- Change in custody or parenting time arrangements exceeding 141 overnights annually
- Birth of additional children creating new support obligations
- Remarriage affecting household income or expenses
The 36-month automatic review provision allows either parent to request a modification review through OCSE every three years regardless of whether income has changed by the 20% threshold, providing a built-in opportunity to ensure support amounts remain appropriate as children grow.
How Arkansas Calculates Child Support Under the Income Shares Model
Arkansas calculates child support using the Income Shares Model established in Administrative Order No. 10, which the Arkansas Supreme Court adopted effective July 1, 2020, replacing the previous payor-income-only method. Under this model, the court combines both parents' adjusted gross monthly incomes and references the Family Support Chart to determine the basic child support obligation, then divides that obligation proportionally based on each parent's percentage of the combined income.
The calculation process follows these steps:
- Determine each parent's gross monthly income from all sources
- Subtract allowable deductions (taxes, mandatory retirement, existing support obligations)
- Calculate the combined adjusted gross income
- Look up the basic support obligation on the Family Support Chart based on combined income and number of children
- Divide the obligation proportionally between parents based on income percentages
- Add pro-rata shares of health insurance, childcare, and extraordinary medical expenses exceeding $250 annually
For example, if Parent A earns $4,000 monthly and Parent B earns $6,000 monthly, the combined income is $10,000. Parent A contributes 40% and Parent B contributes 60%. If the Family Support Chart shows a basic obligation of $1,200 for one child at $10,000 combined income, Parent A would owe $480 (40%) and Parent B would owe $720 (60%). The non-custodial parent typically pays their share directly to the custodial parent.
The Family Support Chart covers combined incomes up to $30,000 per month, with courts exercising discretion for higher incomes. The minimum support obligation is $125 per month, and parents earning less than $900 monthly gross income receive a self-support reserve adjustment based on federal poverty guidelines multiplied by Arkansas's price parity index.
Filing for Child Support Modification Through OCSE
The Arkansas Office of Child Support Enforcement (OCSE) provides a streamlined, lower-cost option for modifying child support, charging an $80 initiation fee compared to $165 for direct circuit court filing. OCSE operates 26 field offices across Arkansas and can be reached at 501-371-5349 or toll-free at 877-731-3071. When you request a modification through OCSE, the agency conducts a preliminary review before initiating legal proceedings to determine whether your circumstances meet the statutory threshold.
To file through OCSE:
- Contact your local OCSE field office or register at www.childsupport.arkansas.gov through MyCase
- Request a formal review of your child support order
- Provide documentation of your income change (pay stubs, tax returns, termination notice, disability determination)
- OCSE will calculate the proposed new support amount using the Family Support Chart
- If modification is appropriate, OCSE files the motion with the court within 30 days
- Both parents receive notice of the hearing date
- A judge must sign any modification for it to become effective
OCSE charges additional fees based on case resolution: $100 for out-of-court settlements, $150 for in-court settlements without trial, and $250 for cases requiring a trial hearing. The agency also charges a 13% administrative fee (capped at $18 monthly) for each month they process a child support payment on your account.
Filing for Modification Directly Through Circuit Court
Filing directly with circuit court costs $165 for paper filing or $185 for electronic filing under Ark. Code § 21-6-403, plus an additional $25-$50 for service of process depending on whether you use the sheriff's office or a private process server. You must file your modification petition with the same circuit court that issued your original child support order, and the modification becomes effective as of the date you serve the other parent with your file-marked motion.
The circuit court filing process involves:
- Obtain the Petition to Modify Child Support form from your local circuit clerk or the Arkansas Judiciary website at arcourts.gov
- Complete the petition with current financial information, including a completed child support worksheet using Administrative Order No. 10 guidelines
- Attach supporting documentation (income verification, proof of changed circumstances)
- File the petition with the circuit clerk and pay the filing fee
- Serve the other parent through certified mail, sheriff service, or private process server
- Retain proof of service and copies of all documents
- Attend the scheduled hearing and present your evidence
- If the judge grants modification, the new order takes effect from the service date
Parents unable to afford filing fees may petition to proceed in forma pauperis. Automatic qualification applies to recipients of SSI, SNAP, TANF, or Medicaid, or those with household income at or below 125% of the federal poverty level (approximately $18,825 per year for a single person in 2026).
Timeline: How Long Does Modification Take
Uncontested child support modifications in Arkansas, where both parents agree on the new support amount, typically resolve within 30 to 60 days after filing, requiring only a judge's signature on an Agreed Order. Contested modifications involving disputes over income, parenting time, or additional expenses commonly take 4 to 9 months to resolve, though complex cases requiring depositions, expert testimony, or multiple court appearances may extend to 12 months or longer.
Key timeline factors:
| Case Type | Typical Duration | Factors Affecting Timeline |
|---|---|---|
| Agreed/Uncontested | 30-60 days | Court scheduling, judge availability |
| Contested (simple) | 4-6 months | Discovery period, single hearing |
| Contested (complex) | 6-12+ months | Expert witnesses, multiple hearings, appeals |
| OCSE-initiated | 30-90 days | Agency review, court scheduling |
The modification effective date is critical: Arkansas law specifies that modifications take effect as of the date of service on the other party of your file-marked motion, not the date of the court's final order. This means if you serve your motion in January but the court hearing occurs in May, the modified support amount applies retroactively to January.
Important warning: Never reduce your child support payments unilaterally based on changed circumstances without a court order. If you stop paying the ordered amount, you remain legally responsible for the full original amount, and arrearages will accumulate with potential enforcement consequences including wage garnishment, license suspension, and contempt of court.
Income Verification Requirements
Arkansas law requires both parents to provide income verification whenever the court orders child support and annually upon written request by certified mail from the other parent under the income disclosure provisions of the child support guidelines. Courts may order income verification through tax returns, pay stubs, W-2 forms, 1099 statements, business financial records, and bank statements. Self-employed parents must provide additional documentation including profit and loss statements, business tax returns, and evidence of business expenses.
Required documentation for modification petitions:
- Last three months of pay stubs or proof of income
- Previous year's federal and state tax returns with all schedules
- W-2 forms and 1099 statements
- Documentation of other income sources (rental income, dividends, retirement distributions)
- Proof of health insurance costs for the child
- Work-related childcare expense receipts
- Evidence of extraordinary medical expenses exceeding $250 annually
- Documentation supporting the claimed change (termination letter, disability determination, promotion notice)
If a parent fails to provide required income documentation, the court may impute income based on the parent's earning capacity, work history, education level, and local job market conditions. Voluntary underemployment or unemployment does not excuse a parent from support obligations, and courts will calculate support based on the income the parent could reasonably earn.
Special Circumstances: Incarceration and Disability
Arkansas treats incarceration as involuntary unemployment for child support purposes under Act 904 of 2019, codified at Ark. Code Ann. § 9-12-312(a) and § 9-14-106(a). Incarceration qualifying for this protection means a conviction resulting in confinement of at least 180 days in a local jail, state or federal correctional facility, or state psychiatric hospital, excluding credit for time served before sentencing. Incarcerated parents may petition for modification, and courts cannot impute income based on pre-incarceration earnings.
Disability affecting earning capacity also qualifies as grounds for modification. Parents receiving Social Security Disability Insurance (SSDI) may have derivative benefits paid to their children credited toward support obligations. The court will consider the extent of disability, prognosis for recovery, and any remaining earning capacity when calculating modified support amounts.
For both circumstances, the modification is not automatic. The affected parent must still file a petition demonstrating the changed circumstances and requesting adjustment. Support arrearages accumulated before filing the modification petition remain enforceable, even if circumstances later change dramatically.
Enforcing and Collecting Modified Support Orders
Once a court issues a modified child support order, Arkansas provides robust enforcement mechanisms through OCSE and the court system. Enforcement tools include income withholding orders requiring employers to deduct support from wages, interception of federal and state tax refunds, suspension of driver's licenses and professional licenses, passport denial for arrearages exceeding $2,500, credit bureau reporting, and contempt of court proceedings that may result in jail time.
OCSE enforcement services:
- Automatic income withholding orders to employers
- Federal and state tax refund intercepts
- Unemployment benefit intercepts
- Workers' compensation intercepts
- Bank account levies
- Property liens
- Credit bureau reporting of arrearages
- License suspension referrals (driver's, professional, recreational)
- Federal parent locator services
- Interstate enforcement through UIFSA (Uniform Interstate Family Support Act)
All child support payments in Arkansas should be processed through the Arkansas Child Support Clearinghouse rather than paid directly between parents. The Clearinghouse maintains official payment records, calculates interest on arrearages, and provides payment history documentation. Contact the Clearinghouse at 501-683-7911 (Little Rock area) or 866-428-8382 (toll-free).
Working With an Attorney vs. Filing Pro Se
Arkansas permits parents to file child support modification petitions pro se (without an attorney), and OCSE provides assistance with the legal process at lower cost than private representation. However, contested modifications involving disputes over income calculation, imputed income, or significant arrearages often benefit from attorney representation. Arkansas family law attorneys typically charge $200-$400 per hour, with modification cases costing $1,500-$5,000 for contested matters.
Consider hiring an attorney when:
- The other parent disputes the income change or contests modification
- Complex income issues exist (self-employment, multiple income sources, stock options)
- Significant arrearages have accumulated requiring negotiation
- Custody or parenting time changes accompany the support modification
- The other parent has legal representation
- Interstate issues complicate enforcement or modification
Pro se filing may be appropriate when:
- Both parents agree on the modified amount
- Income changes are straightforward and well-documented
- No significant arrearages exist
- You qualify for OCSE assistance
- Legal aid services are available through Arkansas Law Help at arlawhelp.org
The Arkansas Access to Justice Commission provides resources for self-represented litigants, including form packets and instructions available through the Arkansas Judiciary website.
Frequently Asked Questions
How much does it cost to modify child support in Arkansas?
Filing a child support modification in Arkansas costs $80 through the Office of Child Support Enforcement or $165-$185 through circuit court, plus $25-$50 for service of process. Additional OCSE fees apply based on case resolution: $100 for out-of-court settlement, $150 for in-court settlement, or $250 for trial. As of March 2026, verify current fees with your local circuit clerk or OCSE office.
What qualifies as a material change for child support modification in Arkansas?
Arkansas law under Ark. Code Ann. § 9-14-107 defines a material change as any 20% or greater change in either parent's gross income, or a change of $100 or more per month. Job loss, promotion, disability, incarceration exceeding 180 days, and significant changes in the child's needs all qualify as material changes warranting modification review.
How long does a child support modification take in Arkansas?
Uncontested modifications where both parents agree typically resolve within 30-60 days. Contested modifications involving income disputes commonly take 4-9 months, with complex cases extending to 12 months or longer. The modification becomes effective from the date you serve the other parent with your file-marked motion, not the date of the court's final decision.
Can I reduce my child support payments without going to court in Arkansas?
No. Arkansas law requires all child support modifications to be signed by a judge. If you unilaterally reduce payments without a court order, you remain legally responsible for the full original amount, and arrearages will accumulate. Always file a modification petition before reducing payments, even if your income has significantly decreased.
How often can I request a child support modification in Arkansas?
You have an automatic right to request a review through OCSE every 36 months. You may request modification sooner whenever a material change occurs (20% income change or $100/month shift). There is no limit on how frequently you can petition for modification if genuine material changes occur.
Does Arkansas consider both parents' incomes for child support?
Yes. Since July 1, 2020, Arkansas uses the Income Shares Model under Administrative Order No. 10, which calculates support based on both parents' combined gross monthly incomes. The Family Support Chart determines the basic obligation, which is then divided proportionally based on each parent's percentage of combined income.
What is the minimum child support amount in Arkansas?
The minimum child support obligation in Arkansas is $125 per month. Parents earning less than $900 in gross monthly income receive a self-support reserve adjustment based on federal poverty guidelines. Courts cannot order support below this minimum except in extraordinary circumstances.
Can incarcerated parents modify child support in Arkansas?
Yes. Under Act 904 of 2019, Arkansas treats incarceration of 180 days or more as involuntary unemployment for child support purposes. Incarcerated parents may petition for modification, and courts cannot impute pre-incarceration income. However, modification is not automatic and requires filing a petition with the court.
When does child support end in Arkansas?
Child support in Arkansas terminates when the child turns 18 or graduates from high school, whichever occurs later, but not past age 19. Arkansas does not require parents to pay for college expenses. Support may continue past these ages for children with disabilities who cannot support themselves.
Where do I file for child support modification in Arkansas?
You must file your modification petition with the same circuit court that issued your original child support order. Alternatively, you can request modification through your local OCSE field office. Arkansas has 26 OCSE offices statewide; contact the Central Office at 501-371-5349 or 877-731-3071 to locate your servicing office.
