Types of Custody in Iowa

Iowa recognizes several types of custody arrangements:

Joint custody presumption: YES — Iowa has a strong statutory preference favoring joint custody. Under Iowa Code § 598.41(2)(a), upon the application of either parent, the court SHALL consider granting joint custody. If the court does NOT grant joint custody when requested, the court must cite “clear and convincing evidence” pursuant to the factors in subsection 3 that joint custody is unreasonable and not in the best interest of the child to the extent that the legal custodial relationship between the child and a parent should be severed. EXCEPTION: If the court finds a history of domestic abuse exists, there is a rebuttable presumption AGAINST awarding joint custody. (Iowa Code § 598.41(2)(b), § 598.41(3)(j))

Iowa Best Interest of the Child Standard

The best interests of the child standard is the primary framework Iowa courts use for all custody decisions. This standard considers what arrangement will best serve the child’s physical, emotional, and developmental needs.

Iowa courts evaluate these best interest factors when making custody decisions:

• Iowa Code § 598.41(3) requires the court to consider the following factors in determining what custody arrangement is in the best interest of the minor child: (a) Whether each parent would be a suitable custodian for the child. (b) Whether the psychological and emotional needs and development of the child will suffer due to lack of active contact with and attention from both parents. (c) Whether the parents can communicate with each other regarding the child’s needs. (d) Whether both parents have actively cared for the child before and since the separation. (e) Whether each parent can support the other parent’s relationship with the child. (f) Whether the custody arrangement is in accord with the child’s wishes or whether the child has strong opposition
• taking into consideration the child’s age and maturity. (g) Whether one or both of the parents agree or are opposed to joint custody. (h) The geographic proximity of the parents. (i) Whether the safety of the child
• other children
• or the other parent will be jeopardized by the awarding of joint custody or by unsupervised or unrestricted visitation. (j) Whether a history of domestic abuse
• as defined in section 236.2
• exists. Additionally
• under § 598.41(1)(c)
• the court shall consider the denial by one parent of the child’s opportunity for maximum continuing contact with the other parent
• without just cause
• as a significant factor in determining the proper custody arrangement. (Iowa Code § 598.41(3))

Child’s preference: In Iowa, a child’s custody preference may be considered when the child reaches No specific age. Iowa does not set a minimum age at which a child may express a custody preference. Under Iowa Code § 598.41(3)(f), the court considers “whether the custody arrangement is in accord with the child’s wishes or whether the child has strong opposition, taking into consideration the child’s age and maturity.” The weight given to the child’s preference depends on the individual child’s maturity and judgment as assessed by the court. A child’s preference is entitled to less weight in a modification proceeding than in an initial custody determination.. The weight given to the child’s preference increases with age and maturity. The court considers the child’s reasoning and whether the preference is influenced by a parent.

Iowa Parenting Plans

Iowa requires parents to submit a parenting plan as part of custody proceedings. An Iowa parenting plan must address: (1) Physical custody and parenting time schedule — where the child lives and the number of overnights for each parent; (2) Legal custody — which parent is responsible for major decisions (education, medical, religious, extracurricular); (3) Holiday, vacation, and school break schedules; (4) How parents will resolve major changes or disagreements affecting the child; (5) How the plan will adapt as the child’s age and developmental needs change; (6) Communication arrangements between the child and each parent. (Iowa Court Rules Form 229; iowacourts.gov self-representation guide)

Key elements of an effective parenting plan:

• Regular residential schedule (weekdays, weekends, overnights)
• Holiday and school vacation rotation
• Transportation arrangements and pickup/drop-off logistics
• Decision-making authority (education, healthcare, extracurriculars)
• Communication methods between parents and between parent and child
• Dispute resolution process (mediation before court)
• Right of first refusal when a parent is unavailable

Iowa Custody Relocation Rules

Under Iowa Code § 598.21D, if a parent awarded joint legal custody and physical care (or sole legal custody) relocates the residence of the minor child to a location 150 miles or more from the child’s residence at the time custody was awarded, the court may consider this a substantial change in circumstances. The relocating parent must provide written notice to the other parent at least 60 days before the intended move. If the court determines the relocation constitutes a substantial change in circumstances, it shall modify the custody order to, at a minimum, preserve as nearly as possible the existing relationship between the child and the nonrelocating parent. Modified orders may include extended visitation during summer/school breaks and scheduled telephone contact. (Iowa Code § 598.21D)

Notice requirement: The relocating parent must provide 60 days advance written notice required before a parent relocates the child’s residence 150 miles or more from the residence at the time custody was awarded. (Iowa Code § 598.21D) days advance written notice to the other parent.

The court evaluates whether the move serves the child’s best interests, considering the reason for the move, the impact on the child’s relationship with the non-moving parent, and whether a modified visitation schedule can preserve that relationship.

Modifying Iowa Custody Orders

Iowa uses a “substantial change in circumstances” standard for modifying custody orders. Under Iowa Code § 598.21C, the court may modify orders when a substantial change in circumstances exists. Factors considered include: changes in employment, earning capacity, income, or resources; receipt of inheritance, pension, or gift; changes in medical expenses; changes in the number or needs of dependents; changes in physical, mental, or emotional health of a party; changes in residence; remarriage; possible support by another person; changes in the physical, emotional, or educational needs of the child; contempt of existing court orders; and entry of a dispositional or permanency order in juvenile court. For custody-specific modifications, the petition is made pursuant to § 598.41 (for joint/sole custody changes) and Chapter 598B (UCCJEA jurisdictional rules). Relocation of 150+ miles under § 598.21D may also constitute a substantial change. (Iowa Code § 598.21C, § 598.21D, § 598.41)

Common modification triggers: parent relocation, change in child’s needs, substance abuse, domestic violence, parent’s work schedule change, child reaching an age where preferences are considered, or one parent consistently violating the existing order.

Special Circumstances in Iowa Custody

Domestic violence: Domestic violence has a significant impact on custody decisions in Iowa. Under Iowa Code § 598.41(3)(j), the court must consider whether a history of domestic abuse exists. If a history of domestic abuse is found, there is a REBUTTABLE PRESUMPTION AGAINST awarding joint custody (§ 598.41(2)(b)). An unrebutted finding of domestic abuse history outweighs consideration of ANY other factor in subsection 3 when determining custody. In determining whether a history of domestic abuse exists, the court considers: commencement of a Chapter 236 action, issuance of a protective order or court order/consent agreement under § 236.5, issuance of an emergency order under § 236.6, holding a parent in contempt under § 664A.7, response of a peace officer to alleged domestic abuse or arrest of a parent, or a conviction for domestic abuse assault under § 708.2A. Additionally, if a parent who is a domestic abuse victim relocates or is absent from the home based on fear of or actual acts/threats of domestic abuse, the court SHALL NOT consider that relocation or absence as a factor against that parent in awarding custody or visitation (§ 598.41(3)(j)). (Iowa Code § 598.41)

Grandparent visitation: YES, but limited. Under Iowa Code Chapter 600C (§ 600C.1), grandparents and great-grandparents may petition for visitation ONLY when the parent who is the child of the grandparent (or grandchild of the great-grandparent) is deceased. The court may grant visitation only if ALL of the following are met: (1) visitation is in the child’s best interest, AND (2) the grandparent/great-grandparent had a “substantial relationship” with the child before filing — demonstrated by the child having lived with them for at least 6 months, the grandparent having financially supported the child for at least 6 months, or the child having visited frequently (including occasional overnights) for at least 1 year. Best interest factors include: prior interaction and interrelationships with parents/siblings compared to the grandparent relationship; geographic distance; available time including work/school schedules; and the child’s age. A grandparent may not petition more than once every 2 years absent good cause. (Iowa Code § 600C.1)

Unmarried parents: Under Iowa Code § 600B.40, the mother of a child born out of wedlock whose paternity has not been acknowledged and who has not been adopted has SOLE CUSTODY by default, unless the court orders otherwise. The father MUST establish paternity before gaining custody or visitation rights. Paternity can be established by: (1) Voluntary Paternity Affidavit — both parents sign an affidavit (typically at the hospital after birth or through the Iowa Department of Public Health), which establishes the father’s legal rights and responsibilities without going to court; (2) Judicial process — the court may order blood or genetic testing of the child, mother, and alleged father (Iowa Code Chapter 600B). Once paternity is established, the father gains legal custody rights and visitation rights and may petition the court for custody or physical care. Custody determinations for unmarried parents follow the same best interest factors as for married parents under § 598.41. (Iowa Code § 600B.40, Chapter 600B)

Guardian ad litem: YES. Under Iowa Code § 598.12, the court may appoint a guardian ad litem (GAL) to represent the best interests of the minor child in custody proceedings. The GAL must be a practicing attorney. GAL duties include: conducting an initial in-person interview with the child (if age-appropriate), interviewing each parent or guardian, visiting the child’s home and any prospective home, and interviewing any person providing medical, mental health, social, educational, or other services to the child prior to any court-ordered hearing. The same person cannot serve as both the child’s attorney and as GAL. The court may also order an investigation by an appropriate agency regarding home conditions, parenting capabilities, and other matters pertinent to best interests; the investigation report is submitted to the court and available to both parties. (Iowa Code § 598.12)

Additional Iowa rules: (1) MAXIMUM CONTACT PRINCIPLE: Iowa law strongly emphasizes that custody arrangements should give the child the opportunity for “maximum continuing physical and emotional contact with both parents” and encourage parents to share rights and responsibilities — unless physical harm or significant emotional harm is likely (§ 598.41(1)(a)). (2) DENIAL OF CONTACT AS SIGNIFICANT FACTOR: The court shall consider one parent’s denial of the child’s opportunity for maximum continuing contact with the other parent, without just cause, as a “significant factor” in determining custody (§ 598.41(1)(c)). This means a parent who obstructs the other parent’s relationship may be disfavored. (3) CLEAR AND CONVINCING EVIDENCE TO DENY JOINT CUSTODY: If either parent requests joint custody and the court denies it, the court must cite clear and convincing evidence — a higher standard than the typical preponderance standard — that joint custody is unreasonable (§ 598.41(2)(a)). (4) 90-DAY WAITING PERIOD: Iowa requires a 90-day waiting period from the date of filing before a divorce can be finalized. (5) DOMESTIC ABUSE VICTIM PROTECTION: A victim-parent’s relocation or absence from the home due to fear of domestic abuse cannot be used against them in custody determinations (§ 598.41(3)(j)). (6) JOINT PHYSICAL CARE NOT PRESUMED: While Iowa favors joint legal custody, there is no statutory presumption favoring joint physical care (equal parenting time); the court awards physical care based on best interests.
