Is there an age limit for adult adoption in Hawaii?

Hawaii's adult adoption law does not set an upper age limit or an age-gap condition. It says "Any person may be adopted under this chapter" (HRS § 578-1), as long as the adult adoptee gives written consent. There is also no relationship or disability condition for the adoptee.

What the law does say about age:

• The person being adopted: They must be an adult who gives written consent. No maximum age appears in the Hawaii provisions.
• The person adopting: HRS § 578-1 allows petitions from "any unmarried adult person, person married to the legal birthing parent or non-birthing parent of a minor child, or married couple jointly." It does not state a numeric age for the adopting adult, so ask the Family Court clerk in your county to confirm that number.
• Age gap: No age-gap rule appears in the sections reviewed. If your situation involves a close age difference, the Family Court clerk or an attorney can tell you how the court views it.
• Existing legal relationship: The person adopting must not already stand in a legal parent-child relationship with the adoptee.

Consent:

• The adult adoptee must consent in writing.
• If the adoptee is married, the spouse's written consent is also needed.
• The adoptee's parents' consent is not required (HRS § 578-2(c)(1)(J)).
• Hawaii's child consent age of 10 applies to minors, so it does not come into play when the adoptee is an adult.

How the process works:

• Court: Your petition goes to the Family Court of the circuit. Venue is where the petitioner(s) live or are in military service, or where the adoptee lives or was born.
• Residency: There is no separate residency requirement.
• Investigation: The court must notify the Director of Human Services and allow time for an investigation and report (HRS § 578-8(a)). The court may waive this by written order if the adoptee's best interests require it (HRS § 578-8(b)).
• Hearing: A hearing is required. The petitioners, any legal parent married to a petitioner, and any adoptee whose consent is required must appear personally unless the court expressly excuses them.
• Timeline: Adult adoptions in Hawaii run about 4-8 weeks.
