Home › Hawaii Estate Planning › Last Will and Testament
Hawaii’s intestacy statute is the only one in the country written for a “surviving spouse or reciprocal beneficiary.” That registered status — created by Hawaii in 1997 for two adults legally barred from marrying each other — still carries full intestate inheritance rights. Hawaii also raised every intestacy dollar figure in 2023, and its amounts are now the highest in the nation: up to $400,000 off the top. Handwritten wills are valid with no witnesses. And Hawaii’s estate tax reaches 20%, the highest top state estate tax rate in the country. Every rule below cites the Hawaii Revised Statutes.
Most Hawaii adults can finish a legally valid will in under an hour.
Two witnesses, a signature, and clear wishes — that’s the whole requirement. An online service like Trust & Will prepares a Hawaii-specific will with the witness pages ready to sign.

Hawaii Will Requirements (2026)
| Requirement | Hawaii rule | Statute |
|---|---|---|
| In writing | Required — Hawaii’s own e-signature law expressly excludes wills | §§ 560:2-502(a)(1), 489E-3(b)(1) |
| Signed | By you, or in your name by another individual in your conscious presence and at your direction | § 560:2-502(a)(2) |
| Witnessed | At least two individuals, each signing within a reasonable time after witnessing your signing or your acknowledgment — they need not be together | § 560:2-502(a)(3) |
| Notarized | Not required for validity — the notary appears only in the optional self-proving affidavit | § 560:2-504 |
Hawaii follows the modern Uniform Probate Code. No publication requirement, no requirement that the witnesses be present together, and a reasonable-time window for their signatures.
Who can make a will: 18 or older and of sound mind (§ 560:2-501).
Handwritten Wills Are Valid in Hawaii
Section 560:2-502(b): a will that does not comply with the witnessed-will requirements is valid as a holographic will, whether or not witnessed, if the signature and material portions of the document are in the testator’s handwriting. No date is required.
And § 560:2-502(c) adds the generous evidentiary rule: intent that the document constitute your will can be established by extrinsic evidence, including, for holographic wills, portions of the document that are not in your handwriting. A preprinted form with the operative terms written in by hand can qualify — the opposite of the rule in “wholly in your own handwriting” states.
Hawaii also has the Uniform Probate Code’s harmless-error provision at § 560:2-503, so a document that fails the formalities may still be admitted on clear and convincing evidence of what you intended. Between holographic wills, a reasonable-time witness rule and harmless error, Hawaii is among the more forgiving states on form.
Electronic Wills Are Not Valid in Hawaii
Hawaii has not adopted the Uniform Electronic Wills Act. Section 560:2-502 lists its exceptions — §§ 560:2-503, 560:2-506 and 560:2-513 — and none is electronic. Hawaii’s Uniform Electronic Transactions Act then carves wills out from the other direction:
“This chapter does not apply to a transaction to the extent it is governed by: (1) A law governing the creation and execution of wills, codicils, or testamentary trusts…” — Haw. Rev. Stat. § 489E-3(b)(1)
An online service can prepare your Hawaii will — that is what these services do. The signing still happens on paper, in front of two witnesses.
Reciprocal Beneficiaries: a Hawaii-Only Status That Still Inherits
Look at the caption of Hawaii’s intestacy statute: “Share of spouse or reciprocal beneficiary.” Every operative clause repeats the phrase. No other state’s intestacy statute is drafted this way.
Hawaii created reciprocal beneficiary registration in 1997 for two adults who are legally prohibited from marrying each other. Same-sex couples were the original occasion, and marriage equality has since removed that group from the category — but the status was never limited to them and it remains available. Two siblings, or an adult child and a parent, cannot marry, and can register as reciprocal beneficiaries.
The consequence for this page is direct: a registered reciprocal beneficiary takes the same intestate share as a spouse under § 560:2-102. If you are registered, the table below describes what your reciprocal beneficiary inherits if you die without a will — and if you are not registered and want a sibling or parent to inherit, a will is the tool, not the assumption.
Dying Without a Will in Hawaii: the Highest Dollar Figures in the Country
Act 158 of 2023 raised all three of Hawaii’s preferential amounts. They are now the largest of any state:
| Your situation | What your spouse or reciprocal beneficiary receives |
|---|---|
| No descendant and no parent survive you | The entire intestate estate (§ 560:2-102(1)(A)) |
| All your descendants are theirs, and they have no others | The entire intestate estate (§ 560:2-102(1)(B)) |
| No descendant, but a parent survives | First $400,000 + 3/4 of the balance (§ 560:2-102(2)) |
| All your descendants are shared, but they have other descendants | First $330,000 + 1/2 of the balance (§ 560:2-102(3)) |
| You have a descendant who isn’t theirs | First $220,000 + 1/2 of the balance (§ 560:2-102(4)) |
Hawaii is the most protective state in this comparison. Even in the hardest case — you have a child from an earlier relationship — the survivor still takes $220,000 off the top plus half the balance. New Hampshire gives $100,000 in that scenario; Maine and Nebraska give nothing off the top at all.
That generosity has a limit worth naming: against Hawaii property values, $330,000 plus half of a house is still not the house. A will that leaves the home outright is the difference between your spouse owning it and your spouse co-owning it with your children.
Hawaii’s Estate Tax Reaches 20% — the Highest State Rate in the Nation
Hawaii has an estate tax under HRS chapter 236E, and its rate schedule is the steepest of any state. Under § 236E-8(b), the tax on the Hawaii net taxable estate — that is, the amount after the applicable exclusion is subtracted — runs:
| Hawaii net taxable estate | Tax |
|---|---|
| $1,000,000 or less | 10.0% |
| Over $1,000,000 to $2,000,000 | $100,000 + 11.0% of the excess |
| Over $2,000,000 to $3,000,000 | $210,000 + 12% of the excess |
| Over $3,000,000 to $4,000,000 | $330,000 + 13% of the excess |
| Over $4,000,000 to $5,000,000 | $460,000 + 14% of the excess |
| Over $5,000,000 to $10,000,000 | $600,000 + 15.7% of the excess |
| Over $10,000,000 | $1,385,000 + 20% of the excess |
On the exclusion amount, we are going to be careful rather than tidy. Section 236E-6 does not state a single figure. It defines the applicable exclusion as equal to the federal applicable exclusion amount; or the exemption equivalent of the unified credit reduced by the decedent’s taxable gifts; or the exemption equivalent of the unified credit “as set forth for the decedent in chapter 11 of the Internal Revenue Code as amended as of December 21, 2017, as if the decedent died on December 31, 2017” — a frozen 2017 figure. For nonresidents the exclusion is prorated by the ratio of Hawaii property to the federal gross estate.
Because the statute gives alternative computations rather than one number, you will see different Hawaii exclusion figures quoted in different places, and we are not going to pick one and present it as settled. If your estate is anywhere near the range where this matters, the number should come from the Hawaii Department of Taxation or a Hawaii attorney working from your actual federal return — not from a table on a website. What is clean and quotable is the rate schedule above, and the 20% top rate.

What a Will Costs in Hawaii
| Route | Typical cost | What you get |
|---|---|---|
| Handwritten | $0 | Valid if the signature and material portions are in your hand — no date needed, but the most-contested format |
| Online service | $199 individual / $299 couple | Hawaii-specific will with witness pages, done in about an hour |
| Hawaii attorney | Flat fees vary — Honolulu runs above the neighbor islands | Custom drafting and counsel, including estate-tax planning and mainland property |
Online pricing verified against Trust & Will’s published rates (August 2026). The Hawaii State Bar Association publishes no fee survey, so we quote no attorney figures we can’t source.

Two Hawaii-specific cautions. If you own property on the mainland as well as in Hawaii, a will alone means probate in more than one state — the classic case for a trust. And if you hold Hawaiian home lands, succession is governed by its own rules and is not a form-fillable question.
What a Hawaii Will Does Not Do
1. A will does not avoid probate. Hawaii probate is a circuit court process on the public record. For the comparison, see what a living trust costs in Hawaii and our guide to avoiding probate.
2. A will does not reduce the Hawaii estate tax. The tax applies with or without one, and at a 20% top rate it is worth planning around if your estate is in range. That planning happens in a trust.
3. A will does not cover incapacity, and does not override beneficiary designations. Pair it with a durable power of attorney and an advance health-care directive — see the five documents every family needs — and keep your beneficiary forms current.
Will vs. Trust for Hawaii Families
Every Hawaii adult needs a will. Hawaii’s intestacy defaults are the most generous in the country, which makes it tempting to do nothing — but generous is not the same as correct. A $330,000 setaside plus half the balance still leaves your spouse co-owning the family home with your children, and no default rule names a guardian for those children.
Hawaii is also one of the states where the trust question has a real numerical component: a 20% top estate tax rate, and the multi-state probate problem that comes with owning mainland property.

FAQ
Does a will have to be notarized in Hawaii?
No. Validity takes your signature and two witnesses, each signing within a reasonable time after witnessing your signing or acknowledgment (§ 560:2-502). The notary appears only in the optional self-proving affidavit (§ 560:2-504).
Are handwritten wills legal in Hawaii?
Yes, with no witnesses, if the signature and material portions are in your handwriting (§ 560:2-502(b)). No date is required, and under § 560:2-502(c) even printed portions of the document can help prove you intended it as your will.
Can I make an electronic will in Hawaii?
No. Hawaii has not adopted the Uniform Electronic Wills Act, and § 489E-3(b)(1) removes wills, codicils and testamentary trusts from the scope of Hawaii’s Uniform Electronic Transactions Act.
Do reciprocal beneficiaries inherit in Hawaii?
Yes. Hawaii’s intestacy statute is captioned “Share of spouse or reciprocal beneficiary” and gives a registered reciprocal beneficiary the same intestate share as a spouse (§ 560:2-102). Reciprocal beneficiary registration is open to two adults who are legally prohibited from marrying each other — two siblings, or an adult child and a parent, for example.
What happens if I die without a will in Hawaii?
Your spouse or reciprocal beneficiary takes the entire estate if you leave no descendant and no parent, or if all your descendants are theirs and they have no others. Otherwise: $400,000 plus three-quarters if a parent survives and you have no descendants; $330,000 plus half if they have outside children; $220,000 plus half if you do (§ 560:2-102). Those amounts were raised by Act 158 of 2023 and are the highest in the country.
Does Hawaii have an estate tax?
Yes, and its top rate is 20% — the highest state estate tax rate in the country — applying above a $10,000,000 Hawaii net taxable estate, with rates starting at 10% (§ 236E-8). The exclusion amount is defined by formula rather than a flat figure in § 236E-6, so check the current number with the Department of Taxation rather than relying on a published table.
