Shared Custody Child Support in Arkansas
The Arkansas Chart assumes the payor has the children fewer than 141 nights a year. When parents share approximately equal time, the court deducts the smaller parent’s share of the basic obligation from the larger and decides what adjustment to make for expenses; between 141 nights and equal time, any adjustment is discretionary.
The 141-overnight assumption
The Chart assumes the payor has the children overnight fewer than 141 nights a year. The Order presumes a traditional visitation schedule is less than 141 nights while a liberal schedule is usually more than 141 (Section II). Above that line the guidelines change.
Approximately equal time: the offset
When the parents share approximately equal time, they complete the Worksheet and Affidavit of Financial Means, and the court determines the basic obligation by deducting the smaller parent’s obligation from the larger in Part II of the Worksheet. For additional child-rearing expenses, the court refers to Line 10 to decide what adjustment, if any, to make to the basic obligation (Section V.2). The court’s online calculator adds the payor’s share of the expenses minus the amount the payor pays.
A worked example
The same parents as in how the Chart works, with approximately equal time: the payor (higher income) earns $4,200 and pays $150 for insurance, the payee earns $2,800 and pays $400 for child care.
| Item | Amount |
|---|---|
| Payor / payee gross income | $4,200 / $2,800 |
| Basic obligation, 2 children (Line 4) | $1,274 |
| Shares of the basic obligation (Line 5) | $764.40 / $509.60 |
| Offset: larger share minus smaller share | $254.80 |
| Expenses: insurance $150 (payor) + child care $400 (payee) | $550 |
| Payor's share of expenses (Line 10) | $330.00 |
| Adjustment: payor’s share minus the $150 the payor pays | $180.00 |
| Presumed order, rounded down | $434 |
With the children living mostly with the payee, the same facts produce $944. The Arkansas child support calculator runs both when you switch to “Approximately equal time.”
Time between equal and the 141-night line
When the parents do not share approximately equal time but each has the children at least 141 overnights a year, they still complete the Worksheet, and the court may consider the time with the payor as a basis for adjusting the amount. In deciding whether to give an additional credit, the court considers any disparity in the parents’ incomes, giving more weight to disparities under 20%, and which parent pays most of the non-duplicated fixed expenses such as routine clothing, extracurricular activities and school supplies. The adjustment is discretionary and based on overnights or overnight equivalents under a court order, so no formula is shown here.
Split custody
When each parent has sole custody of one or more of the children, a Worksheet is completed for each arrangement, each parent’s obligation is based on the children in the other household, and the larger obligation is offset by the smaller (Section V.3).
If a parent does not use the time
The Order states that a deviation can be considered when the payor has more than 141 overnights with the children. The court decides whether the worksheet-based offset is appropriate and may deviate after considering the deviation factors and the child’s best interest.
Frequently asked questions
How does Arkansas calculate child support for equal parenting time?
The court deducts the smaller parent's share of the basic obligation from the larger, then refers to the share of additional expenses to decide what adjustment, if any, to make.
What is the 141-night rule in Arkansas child support?
The Chart assumes the payor has the children overnight fewer than 141 nights a year. A payor with more may qualify for the shared custody adjustment, which the court applies at its discretion unless the time is approximately equal.
Does equal time mean no child support in Arkansas?
No. The higher-income parent can still pay the difference between the two shares of the basic obligation, adjusted for expenses.
Does Arkansas have a formula for 141 to 182 overnights?
No. When each parent has at least 141 overnights but the time is not approximately equal, the court may consider the time with the payor as a basis for an adjustment, weighing income disparity and non-duplicated fixed expenses.
What is split custody in Arkansas?
Each parent has sole custody of one or more of the children. A worksheet is done for each arrangement and the smaller obligation is offset against the larger.
