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.
- Personal property under $100,000 can often avoid probate entirely 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 for personal property with a gross value under $100,000, usable 30 days after death. 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 real property passing to a surviving spouse or single heir, a Petition for Summary Administration or a TOD (transfer-on-death) deed may be the right path instead.
The creditor claim period in Hawaii is 4 months from the date of first publication of notice to creditors. 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 adult witnesses who sign in each other's presence, consistent with 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 must be entirely in the testator's own handwriting and signed by the testator — 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, the spouse typically inherits the entire estate. If the deceased had children from a prior relationship, the spouse receives the first $225,000 plus half the balance; the children share the rest.
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 percentage scales with the length of the marriage, from 3% (one year) to 50% (fifteen or more years). 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. Witnesses cannot be the designated healthcare agent. Witnesses also should not be the principal's healthcare provider or a person who would inherit from the principal under a will or by intestate succession — their testimony could be called into question if the directive is ever challenged.
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 over $13 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.
For small estates under the $100,000 threshold, 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. The affidavit must be signed at least 30 days after the date of death.
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 limited to the probate estate — assets that must pass through Circuit Court. Assets that pass outside probate are not subject to Med-QUEST recovery. 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.
Recovery is waived (not just delayed) 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 for personal property with a gross value under $100,000, usable 30 days after death under HRS § 560:3-1201. Real property is not covered — real estate must go through formal probate, a summary administration petition, 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 will must be entirely handwritten by the testator and signed — 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 ranges from 3% to 50% 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. Recovery is waived while a surviving spouse, minor child, 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.
