Hawaii Adopts 2017 Uniform Parentage Act (Act 298): What Changes January 2026
Hawaii Act 298, effective January 2026, modernizes the state's parentage laws with gender-neutral language, expanded voluntary acknowledgment rights for same-sex couples, and a comprehensive assisted reproduction framework. If you're a Hawaii parent navigating parentage issues—or planning to become one through assisted reproduction or surrogacy—here's what you need to know.
Key Facts: Act 298 Overview
| Aspect | Before Act 298 | After January 2026 |
|---|---|---|
| Statutory language | Gender-specific ("mother"/"father") | Gender-neutral ("parent"/"person who gave birth") |
| Same-sex couples | Required stepparent adoption for non-biological parent | Voluntary acknowledgment at hospital—same as different-sex couples |
| Surrogacy | Fragmented case law, uncertain process | Statutory framework with pre-birth orders |
| Gamete donation | Limited protections | Clear donor/intended parent distinctions |
| Pre-birth orders | Not available | Available for gestational surrogacy |
What Act 298 Actually Changes
1. Gender-Neutral Parentage Language
Act 298 eliminates gender-specific terminology like "mother" and "father" from Hawaii's parentage statutes, replacing them with "parent" and "person who gave birth."
Why this matters: Same-sex couples no longer face additional legal hurdles based on gendered statutory language. Both intended parents can establish parentage through the same mechanisms regardless of their sex or the sex of their partner.
2. Streamlined Parentage for Same-Sex Couples
Before Act 298, a same-sex couple using assisted reproduction typically required stepparent adoption for the non-biological parent—a process costing $1,500-$3,000 and taking 6-12 months.
Under the new law: Both intended parents can be listed on the birth certificate immediately through voluntary acknowledgment of parentage (VAP) signed at the hospital, identical to how different-sex married couples establish parentage.
What this means for Hawaii families: If you're a same-sex couple having a child through assisted reproduction, you can both establish legal parentage at birth without adoption proceedings.
3. Statutory Surrogacy Framework
Act 298 creates clear pathways for surrogacy agreements and gamete donation arrangements, previously governed by fragmented case law.
Pre-birth parentage orders: Hawaii courts can now issue orders establishing intended parents' rights before the child is born when using a gestational surrogate. The birth certificate lists the intended parents—not the surrogate—from day one.
What this means: If you're pursuing surrogacy in Hawaii, you can obtain legal parentage before birth, eliminating uncertainty during the newborn period.
4. Gamete Donor Protections
The new law provides statutory protection for gamete donors who do not intend to parent, preventing donors from being forced into unwanted parental obligations or financial support responsibilities.
What this means: If you donate sperm, eggs, or embryos through proper channels and don't intend to parent, you won't face unexpected custody claims or child support obligations.
Practical Steps for Hawaii Parents
If You're a Same-Sex Couple Planning a Child:
-
Understand your parentage options. Act 298 lets both parents establish parentage through voluntary acknowledgment at the hospital—no adoption required if you meet the statutory requirements.
-
Document your intent before conception. While voluntary acknowledgment is now available, written agreements specifying intended parentage provide additional protection.
-
Complete the VAP at the hospital. Both parents can sign the voluntary acknowledgment form, establishing full legal parentage for both immediately.
If You're Pursuing Surrogacy in Hawaii:
-
Work with a Hawaii reproductive law attorney. The new framework provides clear pathways but requires proper documentation.
-
Execute a compliant surrogacy agreement. Act 298 specifies requirements for valid surrogacy agreements. Ensure yours meets these standards.
-
Obtain a pre-birth parentage order. This directs the hospital to list intended parents on the original birth certificate, avoiding post-birth adoption proceedings.
If You're a Non-Biological Parent Without Legal Recognition:
-
Evaluate your pathway. If you've been co-parenting, you may be able to establish parentage through holding out as a parent under the new framework, or through confirmatory adoption.
-
Gather documentation. Collect evidence of your parental relationship—photographs, school records, medical authorization forms, financial support documentation.
-
Consult an attorney about your options. The best pathway depends on your specific circumstances.
If You're Considering Gamete Donation:
-
Go through proper medical channels. Act 298 protects donors who provide gametes through licensed physicians with appropriate documentation.
-
Execute written agreements before donation. Specify that you don't intend to be a parent, and ensure the intended parents' intent is documented.
-
Understand the protections. Properly documented gamete donation protects you from unexpected parental obligations.
Frequently Asked Questions
Can both same-sex parents be on the birth certificate now?
Yes. Under Act 298, same-sex parents can both be listed on the birth certificate through voluntary acknowledgment of parentage signed at the hospital. This eliminates the previous requirement for stepparent adoption to establish the non-biological parent's rights.
What is a pre-birth parentage order?
A pre-birth parentage order is issued by the court before a child is born in a surrogacy arrangement. It directs the hospital to list the intended parents—not the surrogate—on the original birth certificate. The intended parents are recognized as legal parents from the moment of birth, with no adoption required.
Does Act 298 affect existing parentage relationships?
No. Parentage relationships established before January 2026 remain valid. Couples who completed stepparent adoption before Act 298 have permanent parentage status. The new law provides additional pathways but doesn't disturb existing legal relationships.
How do surrogacy agreements work under Act 298?
Act 298 establishes requirements for valid surrogacy agreements, including:
- Written agreement executed before embryo transfer
- Clear identification of intended parents
- Surrogate's consent to the arrangement
- Court approval for pre-birth parentage orders
Working with a reproductive law attorney ensures your agreement meets all statutory requirements.
What protections do gamete donors have?
Under Act 298, a person who provides sperm, eggs, or embryos for assisted reproduction through a licensed physician is not a parent unless a written agreement designates them as a parent. This protects donors from:
- Unwanted custody claims by intended parents
- Child support obligations
- Unexpected parental rights or responsibilities
What if I'm moving to Hawaii from another state?
Hawaii will recognize valid parentage judgments from other states under the Full Faith and Credit Clause. If you have a parentage order from another jurisdiction and move to Hawaii, register it with the Hawaii court to ensure smooth recognition if disputes arise later.
Does Act 298 change custody rights?
Act 298 strengthens custody rights for non-biological parents who establish legal parentage. Once parentage is established—whether through voluntary acknowledgment, court order, or other statutory pathway—Hawaii courts apply the same custody standards regardless of biological connection.
