Hawaii follows the Uniform Probate Code, which makes estate administration more flexible than in many states — but the islands have their own rules on estate tax, small estate thresholds, and Medicaid recovery that families need to understand. This guide covers the six areas where Hawaii law most affects what you need to do after a death.
Hawaii's UPC-based probate process is more streamlined than many states, but the $100,000 small estate threshold and the state estate tax deserve close attention early on.
- If the gross Hawaii estate is $100,000 or less, personal property can be collected with a simple affidavit — but real property requires a different path.
- Hawaii is one of the few states with both a state estate tax and spousal portability of the exemption.
- Beneficiary designations and living trusts keep assets out of probate — and out of reach of Med-QUEST recovery.
Probate
Probate & Small Estate Rules in Hawaii
Hawaii probate is filed in the Circuit Court of the circuit where the deceased lived. Hawaii is divided into four counties — each corresponding to a circuit: First Circuit (Oahu/Honolulu), Second Circuit (Maui, Molokai, Lanai), Third Circuit (Hawaii Island), and Fifth Circuit (Kauai). There is no Fourth Circuit.
Hawaii adopted the Uniform Probate Code (UPC), which allows informal administration for most uncontested estates. Under informal administration, the personal representative acts without regular court supervision — reducing both cost and court appearances compared to non-UPC states. Formal supervised administration is available when disputes arise or when a beneficiary or creditor requests it.
The small estate affidavit (HRS § 560:3-1201) is available to collect personal property when the gross value of the decedent's Hawaii estate is $100,000 or less; motor vehicles can be transferred this way regardless of value. There is no waiting period — the successor presents the affidavit with a death certificate. The affidavit is signed under oath by the successor, presented to the holder of the property (such as a bank), and does not require court filing. Real property is not covered — Hawaii does not allow real estate to be transferred by small estate affidavit. For estates with property in Hawaii worth $100,000 or less, the court can instead authorize the clerk of the court to administer the estate (HRS § 560:3-1205); a transfer-on-death deed signed before death also avoids probate for real property.
The creditor claim period in Hawaii is 4 months from the date of first publication of notice to creditors (or 60 days after written notice to a known creditor, if later). If no notice is published or served, claims are barred 18 months after death (HRS § 560:3-803). Personal representatives should publish notice promptly to start this clock. Typical Hawaii probate timelines run 6 to 12 months for uncontested estates under informal UPC administration.

Wills
Will Signing Requirements in Hawaii
A valid Hawaii will requires the signature of the testator plus two witnesses, each of whom signs within a reasonable time after watching the testator sign or acknowledge the will (HRS § 560:2-502). Notarization is not required for a standard witnessed will in Hawaii, though a self-proving affidavit — signed by the testator and witnesses before a notary — is available and recommended. A self-proving will is admitted to probate without requiring witnesses to appear in court, which is a practical advantage when witnesses may be unavailable years later.
Hawaii also recognizes holographic wills under HRS § 560:2-502. A holographic will is valid if the signature and material portions are in the testator's own handwriting — no witnesses are required. While legally valid, holographic wills are more frequently challenged in court and harder to administer. A properly witnessed and self-proved will is always preferable.
If no valid will exists, Hawaii's intestate succession law (HRS § 560:2-102) governs how assets are distributed. Under the UPC intestate rules, a surviving spouse's share depends on whether the deceased had children from prior relationships. If all surviving children are also children of the surviving spouse (and the spouse has no other descendants), the spouse inherits the entire estate. If the deceased had children from another relationship, the spouse receives the first $220,000 plus half the balance; the children share the rest. If the children are all shared but the spouse has children from another relationship, the spouse receives the first $330,000 plus half. With no descendants but a surviving parent, the spouse receives the first $400,000 plus three-quarters (amounts updated in 2023).
Hawaii also recognizes the UPC elective share provisions (HRS § 560:2-202). A surviving spouse who receives less under the will than the elective share amount may elect to take a percentage of the augmented estate instead. The share is 50% of the marital-property portion of the augmented estate, and that portion grows with the length of the marriage (HRS § 560:2-203) — so the share runs from 1.5% for a marriage of under a year up to 50% for long marriages, with a $90,000 minimum supplemental amount in some cases. The election must be filed within nine months of death or six months after probate opens, whichever is later.
Advance Directive
Hawaii Advance Health Care Directive
Hawaii uses a combined form called the Hawaii Advance Health Care Directive (AHCD), authorized under HRS Chapter 327E. The form covers both healthcare agent appointment (who makes decisions if you cannot) and treatment preferences (what care you do or do not want). A single document handles what some states split into a separate durable power of attorney for healthcare and a living will.
To be valid, the Hawaii AHCD must be signed by the principal and either two witnesses or a notary public. The designated healthcare agent, the principal's healthcare provider, and a provider's employee cannot be witnesses, and at least one witness must not be a relative by blood, marriage, or adoption or someone who would inherit from the principal (HRS § 327E-3).
Hawaii also recognizes POLST (Physician Orders for Life-Sustaining Treatment) orders. A POLST is a physician-signed medical order governing immediate treatment decisions — it is distinct from the AHCD and can coexist with it. The POLST governs what paramedics and emergency personnel do; the AHCD governs longer-term healthcare decisions and names the agent who can make them.
If you are settling an estate and the deceased had an AHCD on file at a hospital or care facility, request a copy for your records. Facilities are required to honor a valid AHCD, and the document may be relevant if any end-of-life care costs are being reviewed for Medicaid recovery purposes.
Estate Tax
Hawaii State Estate Tax
Hawaii is one of a small number of states that imposes its own estate tax, separate from the federal estate tax. The Hawaii estate tax applies to estates with a taxable value above $5.49 million (confirm the current threshold with the Hawaii Department of Taxation, as the legislature may adjust it). Estates below this threshold owe no Hawaii estate tax, regardless of what federal tax may apply.
Hawaii's estate tax uses graduated rates ranging from 10% to 20% of the taxable estate. The Hawaii estate tax return — Form M-6 — is filed with the Hawaii Department of Taxation, not the probate court. The return is due nine months after the date of death, with a six-month extension available on request. The tax must be paid, or a payment plan arranged, before the estate can be fully closed.
Hawaii also allows a unified credit that offsets the estate tax liability. Estates with assets primarily in real property, a family farm, or a closely held business should consult a Hawaii estate attorney, as special use valuation elections and other planning tools may significantly reduce the taxable amount.
The federal estate tax exemption (currently $15 million per person) is separate from and higher than Hawaii's threshold. Some estates owe Hawaii estate tax but no federal estate tax. Personal representatives should plan accordingly and not assume the federal filing threshold governs the state obligation.
Vehicle Transfer
Transferring a Vehicle After Death in Hawaii
Vehicle registration and title in Hawaii is handled at the county level — each county's DMV office (City and County of Honolulu, Maui County, Hawaii County, Kauai County) processes title transfers. Procedures are largely similar across counties, but confirm with the relevant office before submitting paperwork.
A small estate affidavit can be used to transfer a vehicle without opening probate. The successor presents the affidavit, a certified copy of the death certificate, and the vehicle title to the county DMV. There is no waiting period, and a vehicle can be transferred by affidavit regardless of its value (HRS § 560:3-1201).
For estates that go through formal probate, the personal representative uses Letters Testamentary (issued by the Circuit Court) to authorize the title transfer. The DMV will require Letters Testamentary, a certified death certificate, and the existing title before issuing a new title in the heir's name.
Vehicles held in joint tenancy with right of survivorship pass directly to the surviving joint owner upon presentation of a death certificate — no probate or affidavit required. Similarly, vehicles held in a living trust transfer to the successor trustee without court involvement, which is one of the practical advantages of a revocable trust in Hawaii.
Medicaid Recovery
Hawaii Med-QUEST Estate Recovery
Hawaii's Medicaid program — called Med-QUEST, administered by the Department of Human Services (DHS) — has the right to recover long-term care costs from the estate of a deceased Medicaid recipient who was age 55 or older at the time benefits were received. Recovery applies to nursing facility services, home- and community-based waiver services, and related hospital and prescription drug costs paid by Med-QUEST.
Recovery is generally described as focused on the probate estate — assets that must pass through Circuit Court. Assets that pass outside probate are often outside Med-QUEST recovery, but confirm with the Department of Human Services before relying on that. This includes assets held in a revocable living trust, accounts with named beneficiaries (such as life insurance, retirement accounts, and payable-on-death bank accounts), jointly held property with right of survivorship, and real property subject to a valid transfer-on-death deed.
Under Hawaii law, DHS files a claim only if there is no surviving spouse, or surviving child who is under 21, blind, or disabled (HRS 346-37). A claim is not filed while any of the following is alive:
- A surviving spouse
- A child under age 21
- A blind or permanently disabled child of any age
Before distributing any estate assets, the personal representative should notify DHS of the death and request a determination of any Med-QUEST claim. Distributing assets before resolving a valid Med-QUEST claim can expose the personal representative to personal liability for the amount distributed. DHS has the right to file a claim in the probate proceeding, and that claim must be addressed before the estate closes.
Families who believe a Med-QUEST recovery claim creates an undue hardship — particularly where the home was the deceased's primary asset and a surviving family member continues to live there — can request a hardship waiver from DHS. Hawaii has hardship waiver procedures, though approval is not guaranteed.

Frequently Asked Questions
What is the small estate threshold in Hawaii?
Hawaii allows a small estate affidavit to collect personal property when the gross Hawaii estate is $100,000 or less (vehicles regardless of value), with no waiting period, under HRS § 560:3-1201. Real property is not covered — real estate must go through probate, clerk administration of a small estate (HRS § 560:3-1205), or another transfer path such as a living trust or TOD deed.
Does Hawaii have a state estate tax?
Yes. Hawaii imposes a state estate tax on estates valued above $5.49 million. Rates range from 10% to 20%. Hawaii is unusual in that it allows portability of the state exemption — a surviving spouse can elect to use the deceased spouse's unused Hawaii exemption by filing a timely Form M-6, even if no tax is owed. Missing the filing deadline forfeits this benefit permanently.
Are holographic wills valid in Hawaii?
Yes. Hawaii recognizes holographic wills under HRS § 560:2-502. The signature and material portions must be in the testator's own handwriting — no witnesses are required. However, holographic wills are more frequently challenged in court and harder for executors to administer. A witnessed, notarized, self-proved will is always the better option.
Does a surviving spouse have an elective share right in Hawaii?
Yes. Under HRS § 560:2-202, a surviving spouse may elect to take a share of the augmented estate instead of accepting what the will provides. The share runs from 1.5% to 50% of the augmented estate depending on the length of the marriage. The election must be filed within nine months of death or six months after probate opens, whichever is later.
Does Hawaii recover Medicaid costs from estates?
Yes. Hawaii Med-QUEST recovers long-term care costs from the probate estate of recipients age 55 or older. Assets passing outside probate — living trusts, beneficiary designations, joint tenancy — are not subject to recovery. A claim is not filed while a surviving spouse, child under 21, or blind or disabled child is alive. Notify DHS before distributing any estate assets.
How long does probate take in Hawaii?
Hawaii probate typically takes 6 to 12 months for uncontested estates under informal UPC administration. The creditor claim period is 4 months from first publication of notice. Contested estates or those involving the Hawaii estate tax can take longer. Hawaii's UPC framework allows the personal representative to act without regular court supervision, which speeds up the process compared to non-UPC states.
