Joint Custody in Arkansas: What Parents Need to Know About Act 604

Since Act 604 took effect in 2021, Arkansas courts start every initial custody case with a clear default: joint custody is presumed to be in your child's best interest. That is a significant shift from the old framework, where judges had broad discretion to award primary custody to one parent without a specific statutory presumption pushing them toward equal time.

Here is what joint custody actually means in Arkansas, how the presumption works, and the situations where a court will deviate from it.

What Joint Custody Means Under Arkansas Law

Arkansas distinguishes between two separate dimensions of custody. Legal custody is the authority to make major decisions about healthcare, education, and religious upbringing. Physical custody is the residential placement — where the child actually lives day to day.

Joint custody covers both. Under Arkansas Code Annotated § 9-13-101, joint custody means an "approximate and reasonable equal division of time" between parents, plus shared decision-making on major issues. It does not require a mathematically identical 50/50 split. A 60/40 or even 55/45 arrangement can qualify as joint physical custody, as long as both parents maintain meaningful residential time.

How the Act 604 Presumption Works

Before Act 604, joint custody was merely "favored." Judges could order it or not, based on their reading of the best-interest factors. Now, the statute creates a rebuttable presumption that joint custody is best for the child. A parent who wants sole custody must overcome that presumption with clear and convincing evidence — a high legal standard that requires testimony and documentation producing a firm conviction in the judge's mind.

The presumption can be rebutted under specific conditions:

• Domestic abuse or sex offender status triggers a counter-presumption against shared placement
• Voluntary agreement — both parents agree to a different arrangement
• One parent doesn't request custody at all
• Willful conflict — if a parent deliberately creates conflict to sabotage joint custody, the court may award sole custody to the cooperative parent

One critical detail: Act 604 applies only to initial custody determinations. It does not retroactively change orders entered before July 2021. Parents with pre-2021 orders who want to shift to joint custody still need to file a modification and prove a material change in circumstances.

What 50/50 Parenting Time Looks Like in Practice

Families in Arkansas use several common schedules to divide time roughly equally:

Week-on/week-off works best for school-age children when parents live in the same school district. The child alternates full weeks, typically switching on Friday or Sunday. The main drawback: younger children may struggle with seven consecutive days away from either parent.

2-2-3 rotation gives each parent two weekdays plus alternating weekends, so neither parent goes more than three days without seeing the child. It creates more transitions but works well for toddlers and preschoolers who need frequent contact with both parents.

Both schedules generate roughly 182 overnights per parent — well above the 141-overnight threshold under Administrative Order No. 10 that activates the shared-custody child support offset.

How Joint Custody Affects Child Support

A common misconception: equal custody time eliminates child support. It does not. Under AO10's Income Shares model, child support is calculated by combining both parents' gross monthly incomes and looking up the Basic Child Support Obligation on the state chart. When the arrangement hits 141+ overnights, the court applies the offset method — calculating each parent's obligation as if they were the non-custodial parent, then subtracting the lower from the higher. The higher-earning parent pays the difference.

Even in a perfectly equal 50/50 schedule, the parent earning more will usually owe some child support. The amount depends on the income gap, not the time split alone.

Joint Legal Custody Decision-Making

When parents share legal custody, neither can make unilateral decisions about the child's education, medical treatment, or religious upbringing. Both must collaborate and reach consensus. If they cannot agree, the dispute goes to mediation or back to court — which is why a parenting plan with a clear dispute-resolution clause matters.

Some parents negotiate a hybrid: joint legal custody with one parent designated as the tiebreaker on specific categories (for example, one parent decides education questions while the other decides healthcare). Arkansas courts will approve these arrangements as long as the plan is detailed and serves the child's interests.

Building a Parenting Plan That Supports Joint Custody

Arkansas judges reject vague parenting plans. A joint custody plan needs specific provisions for the weekly residential schedule, holiday and vacation rotations, transportation and exchange logistics, communication rules, and a dispute-resolution mechanism. Counties in Northwest Arkansas — particularly Benton and Washington — maintain their own standard visitation schedules with distinct pickup times and summer blocks, so a plan needs to align with local expectations.

The Arkansas Child Custody and Parenting Plan Guide walks through each of these decisions step by step, including county-specific schedule comparisons and the AO10 child support calculation, so you can draft a plan that fits the Act 604 framework before your mediation session or court date.
