The Hawaii Intermediate Court of Appeals has upheld a family court's decision regarding custody and support orders in the case of M.F. v. C.T. This ruling affects the custody arrangement of two children, determining that their primary physical custody will remain with M.F. The decision is significant as it highlights the court's approach to custody disputes and the standards of evidence required in such cases.

The case began when M.F. and C.T. entered a legal dispute over the custody of their two children. After voluntarily establishing paternity, M.F. filed a petition for custody, visitation, and support orders. The family court held a trial in February 2025, where it awarded joint legal custody to both parents but granted primary physical custody to M.F. C.T. appealed the decision, raising several points of error regarding the family court's findings.

In its ruling, the court noted that the family court had considerable discretion in making custody decisions. The court reviewed the trial's proceedings and the arguments presented by both parties. C.T., who represented himself, raised seven points of error, claiming that the family court made mistakes in its findings regarding educational stability, medical management, and the conduct of the Child Custody Investigation Unit (CIU).

On August 31, 2026, the Intermediate Court of Appeals, led by Presiding Judge Keith K. Hiraoka, along with Associate Judges Kimberly T. Guidry and Daniel M. Gluck, affirmed the family court's decision. The court stated, "The family court possesses wide discretion in making its decisions and those decisions will not be set aside unless there is a manifest abuse of discretion." This ruling underscores the importance of providing adequate evidence when appealing a family court decision.

The court found that C.T. failed to include necessary trial transcripts in his appeal, which made it difficult to review his claims. C.T. argued that the CIU did not record critical interviews, which he believed violated his due process rights. However, the court noted that he did not raise this objection during the trial and therefore could not rely on it in his appeal. The court emphasized that the burden of proof lies with the appellant to demonstrate errors in the record.

Additionally, the court reviewed C.T.'s claims regarding educational stability and medical management. C.T. contended that M.F. did not provide a stable educational environment for the children, citing chronic absenteeism. However, the court found that C.T. did not provide sufficient evidence to support his assertion, and the family court's findings regarding educational stability were upheld.

Furthermore, C.T. challenged the family court's conclusion that M.F. managed the children's medical care. The court found that C.T. did not identify any errors in the family court's findings and that the evidence supported the conclusion that M.F. took the children to their medical appointments.

In addressing C.T.'s concerns about the CIU's investigation, the court ruled that he did not demonstrate bias or error in the investigation process. C.T. claimed that the CIU relied on speculative testimony, but he failed to provide sufficient evidence or references to support this assertion.

The ruling in M.F. v. C.T. has implications for future custody cases in Hawaii. It reinforces the necessity for parties to present a well-supported case in family court and the importance of following procedural rules when appealing decisions. The court's affirmation of the family court's findings sets a precedent for similar cases, emphasizing that the burden of proof lies with the appellant to demonstrate any alleged errors.

Looking ahead, C.T. may consider further legal options, including the possibility of appealing to the Hawaii Supreme Court. However, details on whether he will pursue this route were not available in the court filing. The outcome of this case will likely influence how parents approach custody disputes and the importance of thorough documentation and evidence in legal proceedings.
