The law in plain words
Under Iowa Code 598.41, custody orders aim for "the maximum continuing physical and emotional contact with both parents." The exception is where contact would likely cause harm.
Wondering who usually ends up with custody? Our page on the chances of getting full custody in Iowa explains what the figures can and cannot show.
Legal custody and physical care
Iowa uses these terms, defined in section 598.1.
- Joint legal custody: both parents share decisions about medical care, education, activities and religion. Neither has greater rights.
- Physical care: the right to keep the child's home and handle routine daily care.
- Joint physical care: both parents keep homes, share parenting time and routine care.
The court's self-help pages say joint legal custody "does not necessarily mean" equal time. Many people say "primary physical care" for the parent the child mostly lives with.
Both parents can see the child's medical, school and police records, unless the decree says otherwise.
Is Iowa a 50/50 state?
No. Iowa has no presumption of equal time or joint physical care. The Iowa Supreme Court said so in In re Marriage of Hansen (2007).
- Joint legal custody: if either parent asks, the court must consider it. To refuse it, the judge needs strong, clear proof that it is unreasonable.
- Joint physical care: once joint legal custody is awarded, the court may award joint physical care if either parent asks. To refuse it, the judge must give specific written findings.
In 2025, the House passed a bill to strengthen joint physical care, and the Senate passed one requiring it in temporary orders. Neither became law.
The 11 custody factors
Section 598.41(3) lists factors the court must consider:
- whether each parent would be a suitable custodian
- whether the child would suffer without active contact with both parents
- whether the parents can communicate about the child's needs
- whether both parents actively cared for the child before and since the separation
- whether each parent can support the other's relationship with the child
- the child's wishes, or strong opposition, given their age and maturity
- whether either parent agrees with, or opposes, joint custody
- how close the parents live to each other
- whether joint custody or unsupervised visits would put anyone at risk
- any history of domestic abuse
- whether a parent knowingly let a registered sex offender have access to the child
The Iowa Supreme Court calls this a nonexclusive list. Judges can weigh other facts too.
How judges decide joint physical care
In Hansen, the Supreme Court named four key factors for joint physical care:
- Stability and continuity of care: who has done the hands-on care. Time after separation should roughly track that history.
- Communication and respect: whether the parents can talk and treat each other with respect.
- Conflict: how much the parents fight.
- Daily matters: whether they generally agree on routines.
The court said there is "no iron clad formula." If joint physical care is refused, continuity and past caregiving carry considerable weight in choosing the main parent.
Your child's wishes
Iowa sets no age at which a child decides. The child's wishes, or strong opposition, are one factor, weighed by age and maturity.
The court can appoint a guardian ad litem, an attorney for the child or a custody investigator. A guardian ad litem interviews the child in person if their age is appropriate.
The court can also ask a child to take part in mediation, if that seems advisable.
Mothers' and fathers' rights
In a divorce, neither parent starts ahead. In Hansen, the Supreme Court said courts "must avoid gender bias." There is no preference for mothers over fathers.
Unmarried parents start differently, as the next section explains.
If you were never married
Under Iowa Code 600B.40, an unmarried mother has sole custody if paternity has not been acknowledged. That lasts unless a court orders otherwise.
Once paternity is established, the father can ask for custody or visitation. The same rules as divorce apply, including the 11 factors and the parenting course.
- Paternity affidavit: once filed and registered, it has the same effect as a court judgment of paternity.
- Changing your mind: either signer can cancel it within 60 days, or before a court order about the child if sooner.
- After that: overturning it needs a genetic test excluding the father. It also needs proof of fraud, threats or pressure, or a serious mistake about the facts.
The statute does not say who has custody after an acknowledgment but before any court order. Self-represented parents use the court's Form 401, the Petition for Custody and Visitation (Parents not Married).
Domestic abuse
If a court finds a history of domestic abuse, the law starts from the assumption that joint custody should not be ordered. The abusive parent can try to disprove it. If they cannot, it outweighs every other factor.
- Evidence: protective orders, police called to the scene, arrests and convictions can all show a history.
- Leaving home: once abuse is found, a parent who moved or left out of fear of abuse will not have that held against them.
- Physical care: in Hansen, the court said untreated battering creates a presumption against joint physical care too.
- Mediation: a parent who applies and shows a history of abuse must be excused from court-ordered mediation.
Domestic abuse covers an assault between parents of the same child, whether or not they married or lived together.
Emergency and temporary orders
- Temporary custody in a divorce: the court must decide temporary custody if a parent asks. At least five days' notice and a hearing are required.
- Unmarried parents: once paternity is established, the court may make a temporary custody order.
- No same-day order in a custody case: the divorce and paternity chapters have no custody order without notice.
- Domestic abuse: a temporary protective order can be issued without the other parent present, on good cause. It can include temporary custody or visitation.
- The hearing: must be held 5 to 15 days after the case starts.
- After hours: a judge can issue emergency relief that lasts 72 hours. Since July 1, 2026, a police officer can file it for a victim.
A final protective order lasts up to a year and can be extended. It is free to file.
Moving with your child
Under Iowa Code 598.21D, a move of 150 miles or more may count as a substantial change. This applies when the parent with physical care, or sole legal custody, moves. Distance is measured from the child's home when custody was ordered.
If it does, the court must change the order to preserve the child's relationship with the other parent as nearly as possible. That can mean longer summer and school-break visits, scheduled calls and shared travel.
The statute sets no notice rule. Check your own order, which may require notice.
In Frederici (1983), the Supreme Court said that, between the parents, the parent with physical care has the final say on where the child lives. The other parent can still ask the court to change the order. In that case, a 700-mile move was not enough, alone, to change physical care.
Changing custody
To change custody, the parent asking must prove two things:
- a substantial change in circumstances since the decree, which the court did not expect and which is more or less permanent
- that they have a superior ability to meet the child's needs
The courts call this a "heavy burden." In Harris (2016), shared physical care that did not work as planned justified naming a main caregiver.
If a parent willfully disobeys a custody order, the court can find contempt. Remedies include make-up time, neutral exchange sites or a change of custody.
The parenting course and mediation
- Parenting course: required in every case about custody or visitation, including unmarried parents and modifications. It must be taken within 45 days of service.
- No final order without it: the court cannot enter a final decree until the course is done, unless it is waived.
- Cost: each parent arranges and pays for their own course, such as Children in the Middle.
- Mediation: the court may order it. Iowa's districts must run mediation or a settlement conference in family cases where at least one parent has a lawyer.
- Safety: a parent who applies and shows a history of domestic abuse must be excused from mediation.
Mediation is offered on a sliding fee scale for parents who cannot afford it.
How to file for custody in Iowa
Custody cases are filed in Iowa District Court. Iowa must usually be the child's home state for six months.
- Choose your county. For a divorce, it is where either spouse lives. For unmarried parents, it is the father's county, or where the mother or child lives.
- Use the court's forms. Self-represented parents must use the Iowa Court Rules chapter 17 forms. Unmarried parents start with Form 401.
- File electronically through Iowa eFile, unless the court allows paper.
- Serve the other parent, then take the parenting course within 45 days.
A divorce usually cannot be granted until 90 days after service, unless a judge shortens the wait for an emergency. The Iowa Judicial Branch court forms page lists every form.
How much does it cost to file for custody in Iowa?
Iowa's filing fees rose on July 1, 2026.
| Filing | Fee |
|---|---|
| Custody petition for unmarried parents | $215 |
| Divorce | $285 |
| Other Chapter 598 petitions, such as modifying a divorce decree | $130 |
| Domestic abuse protective order | Free |
If you cannot afford the fees, file an Application to Defer Costs. The court can let you proceed without paying first, though costs may be charged later.
What changed in 2025 and 2026
Iowa's main custody section, 598.41, has not changed since 2019. In 2021, courts gained power to appoint child advocates in cases between unmarried parents.
- July 1, 2026: filing fees rose, and a new law allows family law arbitration with safeguards for children.
- July 1, 2026: police can file after-hours emergency protective order petitions for victims.
- July 1, 2025: courts can no longer order parents to pay for college.
- Bills that failed: stronger joint physical care rules, temporary joint physical care, and adding coercive control to domestic abuse.

Is Iowa a 50/50 custody state?
No. Iowa presumes no equal time and no joint physical care. Joint legal custody is strongly favored, unless there is a history of domestic abuse.
Who has custody if the parents are not married in Iowa?
If paternity has not been acknowledged, the mother has sole custody until a court orders otherwise. A father can ask for custody once paternity is established.
What is joint physical care in Iowa?
Both parents keep homes and share parenting time and routine care. The statute sets no exact split, and the court's self-help pages describe it as equal and regular care.
At what age can a child choose which parent to live with in Iowa?
No age lets a child choose. The child's wishes are one factor, weighed by age and maturity.
How much does it cost to file for custody in Iowa?
Since July 1, 2026, a custody petition for unmarried parents costs $215, and a divorce $285. You can ask to defer the fees.
Can I move with my child in Iowa?
If the parent with physical care moves the child 150 miles or more, it may count as a substantial change. The court must then protect the child's bond with the other parent.
