IN THE MATTER OF THE GUARDIANSHIP OF I.W. AND T.E.

SCWC-XX-XXXXXXX

CERTIORARI TO THE INTERMEDIATE COURT OF APPEALS (CAAP-XX-XXXXXXX; CASE NOS. 5GD151000035 and 5GD151000036 (consolidated))

JUNE 16, 2026

DEVENS, C.J., McKENNA, EDDINS, AND GINOZA, JJ., AND CIRCUIT JUDGE MORIKONE, ASSIGNED BY REASON OF VACANCY

OPINION OF THE COURT BY EDDINS, J.

I.

The right of a parent to raise their child is a fundamental liberty at the heart of our state’s constitutional tradition. This case explores the status of that interest when a parent consents to guardianship.

The right remains intact.

We hold two things.

First, the rebuttable presumption that a fit parent acts in the best interest of their child extends to guardianship proceedings. Consenting to a guardian’s care is not a waiver. The presumption endures despite that consent.

Second, before a family court may set that presumption aside, the due process and privacy protections in article I, sections 5 and 6 of the Hawaiʻi Constitution require clear and convincing evidence of unfitness.

We affirm the Intermediate Court of Appeals (ICA) in result. The ICA identified the correct standard. But we anchor the standard in the Hawaiʻi Constitution.

Two further points. Clear and convincing evidence governs fitness. The preponderance of the evidence standard governs the best interest analysis under Hawaiʻi Revised Statutes (HRS) § 560:5-210(b) (2018) and HRS § 571-46 (2018). And the parental presumption is not a conclusive rule that makes guardianship terminable at will. It is a substantial, but rebuttable, preference that must inform the family court’s assessment of the child’s best interest.

We return the case to the family court for a fitness determination under the correct standard.

II.

A. Factual Background This is a contested guardianship over two children. Now

teenagers, they have lived with their grandparents for nearly a decade. The grandparents seek to keep and expand their role. The mother wants to end it.

Toby and Izzy are the biological children of Mother and Father. (Pseudonyms are used for the minors.) Mother and Father were never married. They broke up when Mother was six months pregnant with their second child, Izzy.

Toby is now sixteen. Izzy is thirteen.

Grandmother is Mother’s mother.

In January 2016, when Toby was five and Izzy was two, Mother and Father consented to appoint Grandmother and her husband, Grandfather, as unlimited co-guardians for them. The guardianship petitions filed by Grandmother and Grandfather (Guardians) stated that “Mother requests assignment of guardianship to petitioners because of inability to care for the [children] due to personal, emotional and financial issues.”

Mother testified that she was then unemployed, on food stamps, without stable housing, and not “in the best position . . . to meet [the children’s] needs and to care for them.” She viewed the arrangement as temporary.

Over four years later, in March 2020, Mother and her boyfriend filed petitions to terminate the children’s guardianships.

Within two months, Grandmother and Grandfather moved the family court to relocate the children from Kauaʻi to Oregon, citing Grandmother’s loss of work during the COVID-19 pandemic. After mediation, the parties stipulated in July 2020 that Grandfather would resign as co-guardian; Grandmother would continue as a limited guardian; and the children would move to Oregon and live with her during the school year, subject to Mother’s custodial time during breaks. The guardianship termination petitions went no further.

Since the move, Toby has been diagnosed with autism and ADHD, and receives specialized school services. Both children began receiving therapy in Kauaʻi, then continued services in Oregon. Caring for the children’s emotional and special needs, and Mother’s ability to manage that care, became a focal point of the fitness dispute that followed.

In December 2021, Grandmother moved to undo the 2020 stipulation, reinstating Grandfather as co-guardian and restoring the guardianship to unlimited.

Then, in February 2022, Mother and her boyfriend filed joint petitions to terminate the guardianships for both children. The boyfriend’s standing to participate in the family court proceedings as an “interested party” was challenged in circuit court, but Guardians later withdrew the motion. At the ICA, Guardians unsuccessfully attempted to strike the

boyfriend’s briefing. The Guardians have not renewed their objections here, and we do not address them.

Father does not seek custody. He supports continuing the guardianship.

1. Family Court Decision The family court held four days of hearings on the termination petition and motion to modify the guardianship.

In January 2023, the family court granted Grandmother’s motion to undo the 2020 stipulation. It denied the petitions for termination of the children’s guardianships.

The family court applied HRS § 560:5-210(b) to the termination question. It invoked the parental presumption from In re Guardianship of Jane Doe, subject to rebuttal. See In re Guardianship of Doe, 93 Hawaiʻi 374, 385, 4 P.3d 508, 519 (App. 2000).

The court assessed Mother’s fitness under the preponderance of the evidence standard. See In re Guardianship of Doe, 106 Hawaiʻi 75, 78, 101 P.3d 684, 687 (App. 2004) (applying a preponderance of the evidence standard to fitness in guardianship proceedings). It found her unfit. The court grounded that determination on Mother’s “limited involvement with her children and her demonstrated lack of knowledge or ability to take into account [the children’s] emotional and special needs.”

The court found that Mother did not “demonstrate an understanding of [Izzy’s] emotional needs nor [Toby’s] special needs relating to his ADHD and [a]utism diagnos[e]s.” The court-appointed guardian ad litem testified that Mother was unable to parent the children. And Mother, the court found, “made little to no attempt to show that it is in the children’s best interest to have the guardianship terminated.” She relied solely on the parental presumption. Because Mother was not fit, the court concluded, the presumption was rebutted.

The family court then reviewed the HRS § 571-46 best interest factors. It concluded that Grandmother and Grandfather’s unlimited guardianship served the best interest of the children.

Mother and her boyfriend appealed.

2. ICA Memorandum Opinion The ICA held that the family court applied the wrong standard of proof when it found Mother unfit to parent Toby and Izzy. In its formulation, “the court may override parental consent in a proceeding to appoint a guardian or to terminate a guardianship created by parental consent only if it finds by clear and convincing evidence that the parent is unfit, i.e., is unwilling or unable to exercise their parental rights.” (Emphasis added.) Matter of Guardianship of I.W., No. CAAP-23- 0000356, 2025 WL 3215249, at *15 (Haw. App. Nov. 18, 2025).

The ICA identified HRS § 560:5-210 as the operative statute for termination and other post-appointment proceedings. It authorizes “any order that is in the best interest of the ward.”

The court then turned to its earlier decision in In re Guardianship of Doe, 106 Hawaiʻi at 78, 101 P.3d at 687, which held that the preponderance standard governs parental fitness when appointing a guardian. The statute at issue was HRS § 560:5-204 (2018), which covers the initial appointment of guardians. Id.
