Johnson County Courthouse — Iowa City
417 S Clinton St, Iowa City. All custody, support, paternity, adoption, guardianship, juvenile, and CINA cases for Coralville residents are filed and heard at the Johnson County Courthouse — there is no separate family court building. Juvenile matters often run on a separate calendar.
What "family law" covers in Iowa
- Child custody — legal custody and physical care, post-divorce and never-married parents
- Child support — establishment, enforcement, modification
- Paternity — establishing the legal father of a child
- Modifications — changing custody, support, or visitation when circumstances change

- Guardianship & conservatorship — over minors, or over adults who can no longer manage their own affairs
- Juvenile delinquency — when a minor is charged with what would be a crime
- CINA — Child in Need of Assistance — when the state alleges a child is being abused, neglected, or otherwise at risk
- Termination of parental rights (TPR) — by consent (relinquishment) or involuntarily
- Grandparent and third-party visitation — limited in Iowa

Iowa's "best interest of the child" standard
Every custody decision is governed by what serves the best interest of the child. The factors are codified at Iowa Code 598.41 and include:
- Whether each parent would be a suitable custodian
- Whether psychological and emotional needs and development will suffer due to lack of contact with both parents
- Whether the parents can communicate about the child
- Whether both parents have actively cared for the child before and after separation
- Whether each parent supports the child's relationship with the other parent
- Whether the custody arrangement is in accord with the child's wishes (more weight as the child gets older)
- Whether one or both parents agree or oppose joint custody
- The geographic proximity of the parents
- Whether the safety of the child, other children, or the other parent will be jeopardized — including any history of domestic abuse
Legal custody vs. physical care
Iowa distinguishes two concepts that other states often blur:
Legal custody
Legal custody is decision-making authority — schools, medical care, religion, major life choices. Iowa strongly favors joint legal custody, and grants it unless one parent is unfit or there's a history of abuse. Joint legal custody is the default outcome in nearly every case.
Physical care
Physical care is where the child lives day-to-day. Options:
- Sole physical care with one parent (the other gets visitation)
- Joint (shared) physical care — roughly 50/50 time
- Split physical care — siblings divided between parents (rare; disfavored)
Iowa courts have moved steadily toward shared physical care when both parents are fit and live near each other. But it's not automatic. The court still asks whether shared care fits this child and this set of parents.
Child support — the Iowa Guidelines
Iowa uses an income shares model. The court estimates what the parents would have spent on the child if they were still together, and divides that amount between them in proportion to their incomes. The math is set out in the Iowa Child Support Guidelines, available on the Iowa Judicial Branch website.
| Input | What's counted |
|---|---|
| Gross income | Wages, self-employment, bonuses, regular overtime, certain benefits |
| Deductions | Taxes, FICA, mandatory retirement, health insurance for the child, prior-order support |
| Net monthly income | Used in the guideline chart |
| Parenting time credit | Adjustments for extraordinary visitation or shared care |
| Health insurance & childcare | Allocated by income share |
The guideline result is presumed correct. A judge can deviate only on findings that the guideline amount would be unjust or inappropriate. Self-employment income gets scrutinized more carefully.
Modification — substantial change in circumstances
Custody, physical care, and child support orders can be modified after the decree, but you must show a substantial change in circumstances that was not contemplated when the prior order was entered. Common grounds:
- A parent's relocation
- A significant change in either parent's income (typically a deviation of 50% or more for support; less for some cases)
- A child's evolving needs (school, medical, special needs)
- A parent's remarriage, household changes, or new partner of concern
- The child's preference (more weight with age and maturity)
- A pattern of denied visitation or failure to co-parent
Modification of custody is harder than modification of support — Iowa courts disfavor disrupting a child's settled arrangement absent a strong showing.
Paternity
For never-married parents, paternity has to be legally established before the court can order custody, visitation, or support. Two routes:
- Voluntary acknowledgment — both parents sign an Iowa Paternity Affidavit, often at the hospital. Carries the force of a court order.
- Court-ordered paternity action — filed by either parent or by the Child Support Recovery Unit. Genetic testing if disputed.
Once paternity is established, the court can address custody, physical care, visitation, and support in the same case.
Adoption
Three common Iowa adoption paths:
- Step-parent adoption — usually the most straightforward; biological parent's rights must be terminated (by consent or by court finding).
- Agency or private adoption — through a licensed Iowa adoption agency. Home study required.
- International adoption — overlays federal law (Hague Convention countries) and Iowa procedures. Slower; more expensive.
All Iowa adoptions require a home study (with limited exceptions for step-parents) and a court hearing finalizing the adoption.
Guardianship & conservatorship
A guardianship over a minor or incapacitated adult is appointment of someone to make personal decisions for them. A conservatorship covers finances. Iowa updated its guardianship and conservatorship code in 2019 — courts now look for the least restrictive alternative (powers of attorney, supported decision-making) before imposing one.
Juvenile court & CINA
When the Iowa Department of Health and Human Services (formerly DHS) believes a child is being abused, neglected, or otherwise at risk, it can file a Child in Need of Assistance (CINA) petition in juvenile court. CINA cases can lead to in-home services, foster care, and ultimately termination of parental rights. Get a lawyer immediately if HHS contacts you about your children — public defenders are appointed for indigent parents in CINA and TPR cases.
Separately, juvenile court handles delinquency proceedings when a minor is alleged to have committed an act that would be a crime if committed by an adult.
Grandparent visitation
Domestic violence & protective orders
If you are being threatened or harmed by a household member, you can petition for a Civil Protective Order (Chapter 236). Temporary ex parte orders can be issued the same day. A full hearing follows within about two weeks. Violation of a protective order is a criminal offense. Iowa Legal Aid and the Domestic Violence Intervention Program (DVIP) based in Iowa City both assist Coralville-area survivors.

FAQ — Iowa family law
What does "best interest of the child" really mean?
It's a balancing of statutory factors in Iowa Code 598.41 — stability, communication between parents, each parent's history of caregiving, geography, the child's wishes, safety, and more. There's no formula; the judge weighs the factors based on the evidence.
At what age can my child decide which parent to live with?
Never, technically. There's no age at which a child's preference controls. But Iowa judges give increasing weight to the child's reasoned preference as the child gets older — typically meaningful around age 12–14, and substantial in the late teens.
Is Iowa a "50/50 custody" state?
Joint legal custody is the default. Joint physical care (roughly 50/50 time) is increasingly common but not automatic — the court applies the best-interest test and looks at the parents' ability to cooperate, geography, and the child's needs.
Can I move out of state with my kids?
If you have sole physical care, a long-distance move of typically 150 miles or more requires giving the other parent 30 days' notice and may justify a custody modification. The non-moving parent can ask the court to block the move or modify physical care.
What if the other parent stops paying support?
Contact the Iowa Child Support Recovery Unit (CSRU). They can issue income withholding orders, intercept tax refunds, suspend licenses, and refer the case for contempt. You don't need a lawyer to use CSRU services, though contempt actions often involve one.
