How to File a Petition to Modify Custody in Arkansas

To file a petition to modify custody in Arkansas, you reopen the original case in the circuit court that issued your current order, file a petition and sworn affidavit explaining what has changed, pay a $50 filing fee, and formally serve the other parent. Before the judge will even consider changing custody, you have to prove two things: that a material change in circumstances has occurred since the last order, and that the change you’re asking for serves your child’s best interest.¹

What You Have to Prove

Arkansas treats custody modification as a two-step analysis. Step one is the material change in circumstances. Step two is the best interest of the child. If you can’t clear step one, the court never reaches step two, and this is where most petitions fail.¹

The statute doesn’t catalog every qualifying situation, but Arkansas case law recognizes things like a parent’s relocation, a major schedule change, the onset of substance abuse, or one parent repeatedly blocking the other’s access to the child. Smaller changes can also combine into something significant enough to justify revisiting custody. The statute specifically addresses one scenario: if a parent deliberately creates conflict to undermine a joint custody arrangement and the court cannot craft an order to reduce that conflict, the court may treat the behavior as a material change and award primary custody to the other parent.¹

Best interest is the second gate. Judges weigh the child’s need for stability, each parent’s ability to meet the child’s physical and emotional needs, and which parent is more likely to encourage the child’s ongoing relationship with the other parent. A child who is old enough and mature enough to express a meaningful preference may be heard on that too. Where there is evidence of a pattern of domestic abuse by one parent, Arkansas law creates a rebuttable presumption that placing the child with the abusive parent is not in the child’s best interest, shifting the burden to that parent to overcome it.¹

Documents and Information to Gather First

Before you draft anything, pull together what you’ll need:

The case number and date of the original custody order. The modification is filed inside that existing case.
Full legal names, dates of birth, and current addresses for both parents and every child covered by the order.
Evidence of the change you’re claiming: pay stubs for income changes, police reports, school or medical records, communications showing denied visitation, anything concrete that supports your account.

You will file two documents: a petition to modify custody and a sworn affidavit laying out the specific facts that justify your request. Be concrete. “The other parent moved 200 miles away and the child has missed 30 days of school” carries weight; “circumstances have changed” does not. The Arkansas Judiciary posts standard court forms at arcourts.gov, and your local circuit clerk can tell you whether your county requires anything additional.

Where to File and What It Costs

File your petition and affidavit with the circuit clerk in the county where the original order was issued. Because you’re reopening an existing case rather than starting a new one, the statutory filing fee is $50.² Some counties add small state-authorized surcharges, so confirm the exact amount with the clerk before you go.

If you can’t afford the fee, you can ask the court to waive it by filing a motion to proceed in forma pauperis under Rule 72 of the Arkansas Rules of Civil Procedure. The judge reviews your financial situation and, if satisfied you cannot pay, allows the case to proceed without the fee.²

Serving the Other Parent

Once the clerk files your petition, the other parent must receive formal notice. Arkansas allows several methods:

Sheriff’s service, where the sheriff or a deputy in the other parent’s county delivers the papers in person.
An appointed process server, which the court can authorize for any person at least 18 years old.
Certified mail with restricted delivery and return receipt requested, addressed to the other parent by name. If delivery is refused, you must follow up with first-class mail and a notice that the case will proceed and a default judgment may be entered.

Costs vary. Sheriff’s fees differ by county, private process servers typically run from $40 to over $100 depending on how hard the other parent is to find, and certified mail is the cheapest route. File the proof of service with the court as soon as it’s complete. The case cannot move forward without it.

What Happens After the Other Parent Is Served

The other parent generally has 30 days from service to file a written response. An agreement moves things quickly. A disagreement produces an answer and sets the case on a contested track. Silence doesn’t hand you a win automatically, but the court may proceed without the other parent’s input.

Arkansas circuit courts have authority to order parents into mediation before holding a full hearing on custody or visitation.³ A neutral mediator helps both sides negotiate; any agreement you reach can be submitted for the judge’s approval, which is faster and cheaper than trial. If mediation fails, the case moves toward a hearing. A party can ask the court to dispense with mediation for good cause, such as a history of domestic violence.

While everything is pending, the judge can enter temporary orders governing where the child lives, visitation, and support. These stay in place until the final ruling. If the child is in immediate danger, raise it with the court as early as possible, because courts have broad discretion to fashion protective temporary relief.

The Hearing

If the parents don’t settle, the judge sets a hearing. Both sides present evidence, call witnesses, and argue. Your burden at the hearing is the same two-step: material change in circumstances, then best interest. Bring organized exhibits and witnesses who can speak to the facts in your affidavit.

In some cases the judge will appoint an attorney ad litem to represent the child’s interests. A circuit judge may do this whenever it would help resolve the case and protect the child’s rights.⁴ The ad litem may interview the child, speak with teachers and doctors, review records, and participate in the hearing. Their recommendation carries weight with the judge but is not binding.

There is no fixed timeline. An uncontested case can wrap up within a few weeks of filing. A contested case can take several months once you factor in scheduling, discovery, mediation, and court availability. Responding promptly to every court deadline is the single most effective thing you can do to keep the case moving.

If an Out-of-State Order or Move Is Involved

Arkansas has adopted the Uniform Child-Custody Jurisdiction and Enforcement Act, which decides which state’s courts can modify a custody order. An Arkansas court generally cannot modify an order issued by another state unless Arkansas now has jurisdiction to make an initial custody determination and either the original state gives up jurisdiction or all parties have left it.⁵ The reverse also holds: if the Arkansas court issued the original order and you still live here, Arkansas typically keeps exclusive jurisdiction to modify it even after the other parent leaves. If everyone has left Arkansas, you’ll usually need to file in the child’s new home state. Sorting jurisdiction out first saves months of wasted work.

Enforcing the New Order

A modified custody order is enforceable the moment the judge signs it. If the other parent refuses to comply, the usual remedy is a motion for contempt. A parent found in contempt may face fines, makeup visitation for the other parent, mandatory counseling, or jail time in serious or repeated cases. If the other parent has moved out of state, the UCCJEA lets you register the Arkansas order in that state and ask its courts to enforce it.⁵

Practical Cautions

Filing without a lawyer is possible, and plenty of Arkansas parents do it. Contested cases involving domestic violence, relocation, or complex finances benefit from counsel. Family law attorneys in Arkansas typically charge between $150 and $400 per hour and usually ask for a retainer up front. Arkansas Legal Aid and similar organizations may be able to help if you can’t afford private representation.

A few things consistently derail petitions: filing in the wrong county, leaving the original case number off the paperwork, delaying service, and showing up to a hearing with disorganized evidence. A custody modification is a lawsuit with real procedural rules, and the court will expect you to follow them whether or not you have an attorney.
