Relocation and Inter-Island Custody Travel in Hawaii

Hawaii's geography makes custody logistics fundamentally different from mainland states. When parents live on different islands — Oahu and Maui, the Big Island and Kauai — every custody exchange involves flights, advance planning, and costs that add up fast. And when a parent wants to relocate, whether to another island or out of state, the existing custody arrangement may need to be rebuilt from scratch.

Inter-Island Custody: The Logistics

When co-parents live on separate islands, the parenting plan must address specifics that mainland plans never deal with:

Who accompanies the child on flights: For younger children, your plan should specify whether a parent or approved escort accompanies the child and which parent handles each leg of the trip.

Unaccompanied minor age threshold: Airlines have their own unaccompanied-minor policies. Your parenting plan should specify the age at which the child can fly alone, consistent with the current carrier's rules and route.

Flight notification requirements: Require the traveling parent to provide flight details (airline, flight number, arrival time) at least 48–72 hours before travel. This prevents last-minute changes that disrupt the receiving parent's schedule.

Cost allocation: Inter-island tickets and escort costs can add materially to each exchange. Common splits include 50/50, proportional to income, or the traveling parent bears the cost of their own ticket while the receiving parent covers the child's.

Backup plans: Flights get canceled. Weather delays happen. Your plan should address what happens when a flight is canceled — who absorbs the cost of rebooking, how does it affect the parenting schedule, and is there a makeup provision.

Relocation Rules

Hawaii law requires advance written notice before either parent moves with the child: at least 60 days for an inter-island move and 90 days for an out-of-state relocation. The notice must include:

• The new address
• The reason for the move
• A proposed revised parenting schedule

Moving without the other parent's written consent or a court order is prohibited. A parent who relocates unilaterally risks an enforcement action and a request to modify custody.

How Courts Evaluate Relocation Requests

When a parent petitions to relocate with the child, the court weighs the move against the sixteen best-interest factors under HRS § 571-46(b). Key considerations include:

The reason for the move: A job opportunity, returning to a family support network, or pursuing education carries more weight than moving without a clear purpose. Courts are skeptical of moves that appear designed to distance the child from the other parent.

The impact on the child's relationship with the non-moving parent: If the move will make regular in-person contact impractical, the court considers whether technology (video calls, phone access) and extended summer or holiday visits can maintain the relationship.

The child's ties to the current community: School enrollment, friendships, extracurricular activities, extended family connections, and medical providers all factor in. A child deeply rooted in their current community has stronger arguments for staying.

Family violence: A victim-parent who relocates or is absent from the family home to escape family violence cannot be penalized for doing so. The safety and well-being of the child and victim-parent are primary, and HRS § 571-46(a)(9) creates a rebuttable presumption against placing the child in sole custody, joint legal custody, or joint physical custody with the perpetrator.

Drafting Relocation Clauses in Your Parenting Plan

Even if you have no plans to move, your parenting plan should include relocation provisions. Life changes — job transfers, family emergencies, new relationships — can make a move necessary years after the divorce.

Strong relocation clauses address:

• Written notice requirements (timeline and content)
• The right of the non-moving parent to object and petition the court
• Temporary schedule modifications during the transition period
• How travel costs shift if one parent moves farther away
• Communication technology requirements to maintain the child's relationship with the distant parent

The Financial Reality

Inter-island custody is expensive. A parent on Oahu with a child on Maui may spend hundreds per round trip, with exchanges every week or two. Regular exchanges can total thousands per year in travel alone, on top of maintaining two island households in one of the country's highest cost-of-living states.

Build these costs into your negotiations. The Hawaii Child Custody & Parenting Plan Guide includes inter-island travel templates with clauses for flight logistics, cost-sharing, and notification protocols designed specifically for Hawaii's island-to-island custody reality.
