150 Mile Relocation Rule in Iowa Custody Cases

The 150-Mile Threshold Triggers a Formal Process

Under Iowa Code § 598.21D, a parent who proposes to relocate the child's primary residence more than 150 miles from the current home must provide advance written notice to the other parent. The statute uses a 150-mile threshold. Moves within that radius — even if they cross county lines — do not trigger the formal statutory notice requirement, though they can still be grounds for a custody modification if they make the existing parenting schedule unworkable.

This 150-mile rule applies to qualifying in-state and out-of-state moves. A move such as Des Moines to Dubuque (approximately 190 miles) exceeds the threshold.

What the Notice Must Include

The relocating parent must provide advance written notice. The notice should address:

• The proposed new address or general area
• The reason for the move (job transfer, family support, remarriage, etc.)
• A proposed revised parenting schedule that accounts for the increased distance
• A date the move is planned to occur

Give the other parent advance notice well before the planned move, and check the current order and court instructions for the timing requirements that apply to your case. Springing a relocation on the other parent with a week's notice will not go over well with a judge.

The Non-Moving Parent Can Object

After receiving notice, the non-moving parent can file an objection with the court, requesting that the move be blocked or that custody be modified. This triggers a hearing where the relocating parent bears the burden of proving the move serves the child's best interests.

The court evaluates several factors:

The reason for the relocation. A legitimate job opportunity, proximity to family support, or remarriage carries more weight than a desire for a change of scenery. Courts are skeptical of moves that appear designed to interfere with the other parent's relationship.

Impact on the child's relationship with both parents. The core question: can the child maintain meaningful, regular contact with the non-moving parent after the move? The greater the distance, the harder this becomes — and the more creative the proposed schedule needs to be.

The child's ties to the current community. School enrollment, friendships, extracurricular activities, extended family relationships, and medical providers all factor in. Uprooting a child with deep community ties requires stronger justification.

The feasibility of a modified schedule. A parent proposing a 300-mile move needs to offer a realistic alternative parenting schedule — longer summer blocks, alternating school breaks, regular video communication. Simply saying "we'll figure it out" is insufficient.

The child's preference. For older children, the court may consider the child's wishes, weighted by age and maturity.

Moves Under 150 Miles Still Matter

The 150-mile rule is a statutory trigger for the formal notice process, not a safe harbor. A parent who moves 100 miles away — far enough to change school districts and make midweek transitions impossible — can still face a custody modification petition from the other parent.

The difference is procedural: moves under 150 miles do not require the formal advance notice under § 598.21D, but the other parent can still file a modification petition arguing that the move constitutes a substantial change in circumstances that makes the existing order unworkable.

What Happens If You Move Without Notice

Relocating without providing the required notice can affect how the court evaluates the relocation, custody, and parenting schedule. The other parent can ask the court to modify the arrangement if the move makes the existing schedule unworkable.

Even if you believe the move is clearly in the child's best interests, follow the notice process. Bypassing it can damage your credibility with the court.

Plan the Parenting Schedule Before the Move

If you are the moving parent, the strongest thing you can do is present a detailed, workable modified parenting schedule alongside your relocation notice. Show the court exactly how the child will maintain regular contact with the other parent — extended summer time, alternating holidays, weekend visits during school breaks, daily video calls.
