Will requirements in Hawaii
Hawaii will not accept a handwritten will made here, but it does accept one that was valid where it was executed — a meaningful distinction in a state where many residents arrive from elsewhere.
Hawaii's most useful rule is about wills made somewhere else. A handwritten will executed in Hawaii is not valid here — but a holographic will that was validly executed in a state that recognises them will be accepted. For a state where a large share of residents arrive mid-life from the mainland, that distinction does real work.
Otherwise Hawaii follows the Uniform Probate Code closely. Two witnesses or a notarized acknowledgment, no penalty for a beneficiary who signs as a witness, and self-proving affidavits available.
Who can make a will in Hawaii
At a glance
18 or older, and of sound mind
Hawaii requires you to be at least 18 and of sound mind at the time of signing. Capacity asks whether you understood the general nature of your property, who would naturally inherit, and what you were signing.
Witness requirements
How many witnesses
Two witnesses, or a notarized acknowledgment
HRS § 560:2-505
No purge — the gift survives
A witness who inherits under the will does not lose the gift
Hawaii requires two witnesses, or accepts a will acknowledged before a notary as an alternative to witnessing.
On interested witnesses Hawaii follows the Uniform Probate Code: signing as a witness does not invalidate the will or forfeit the gift. Two disinterested witnesses remain the safer choice against an undue-influence claim.
Whatever Hawaii allows, the safe practice is the same everywhere: use two disinterested witnesses who inherit nothing under the will.
Notarization and self-proving affidavits
At a glance
Notarization is not required for validity; a self-proving affidavit is available, and a notarized acknowledgment can substitute for witnesses
A Hawaii will does not need a notary to be valid, but notarization serves two purposes: it can substitute for witnesses, and on a witnessed will it produces a self-proving affidavit.
The affidavit matters especially in Hawaii, where witnesses may relocate to the mainland and become genuinely difficult for an executor to reach. Removing the need to find them later is worth the small effort at signing.
Handwritten (holographic) wills
At a glance
Not valid if made in Hawaii; recognized only if the will was valid where it was executed
Hawaii does not recognise holographic wills executed here. Writing a will by hand in Hawaii, without witnesses, does not produce a valid will.
But Hawaii will honour a holographic will that was valid where it was executed. Someone who wrote a valid handwritten will while living in California or Arizona, then moved to Hawaii, may find it recognised.
The safer course is still to execute a fresh, properly witnessed Hawaii will after you move. Relying on the out-of-state exception means your executor must prove where the will was made and that it satisfied that state's law — a burden you can avoid entirely.
Small estate procedure
At a glance
Hawaii offers a simplified small-estate process below a statutory threshold
Confirm this with the Hawaii State Judiciary probate resources or the circuit court.
Hawaii allows small estates to be handled through a simplified procedure rather than full probate, subject to a statutory limit and a waiting period.
Confirm the current figure with the Hawaii State Judiciary before assuming an estate qualifies. Note also that Hawaii real property frequently pushes estates past small-estate limits even when other assets are modest.
Community property or common law
At a glance
Common law (separate property) state
Hawaii is a common law property state. Ownership follows title rather than being automatically split between spouses because property was acquired during the marriage.
Hawaii provides an elective share for surviving spouses, and it also recognises reciprocal beneficiary relationships, which can affect inheritance rights. That is a Hawaii-specific status worth raising with an attorney if it applies to you.
Advance directives and powers of attorney
At a glance
Statutory advance health-care directive under the Uniform Health-Care Decisions Act; Hawaii follows the Uniform Power of Attorney Act
Hawaii's advance health care directive follows the Uniform Health-Care Decisions Act, combining an appointment of a health-care agent with your treatment instructions in a single document.
For financial matters Hawaii has adopted the Uniform Power of Attorney Act, so its statutory form is broadly consistent with other UPOAA states — helpful for residents who keep accounts on the mainland.
Frequently asked about Hawaii wills
- I have a handwritten will from the mainland. Is it valid in Hawaii?
- Possibly. Hawaii does not recognise holographic wills executed in Hawaii, but it will accept one that was validly executed in a state that does recognise them — such as California, Arizona, or Texas. The practical difficulty is that your executor has to prove where it was made and that it met that state's requirements. Executing a fresh, properly witnessed Hawaii will removes that burden entirely.
- Can I write my own will by hand in Hawaii?
- Not as a valid will. A handwritten, unwitnessed will executed in Hawaii is not recognised. You need two witnesses, or a will acknowledged before a notary — Hawaii accepts notarization as an alternative to witnessing. A handwritten document without either has no effect here.
- Do I need witnesses if my Hawaii will is notarized?
- No. Hawaii accepts a notarized acknowledgment as an alternative to two witnesses. Many people still use both, since a witnessed will with a self-proving affidavit is the most straightforward for an executor to admit to probate, particularly if your witnesses have since moved away.
- Does a beneficiary lose their gift by witnessing my Hawaii will?
- No. Hawaii follows the Uniform Probate Code, so an interested witness neither invalidates the will nor forfeits their inheritance. Using two disinterested witnesses is still better practice, because it removes an easy argument for anyone contesting the will on undue-influence grounds.
This is not legal advice
This page is general information about Hawaii law, not legal advice, and reading it does not create an attorney-client relationship. Statutes change, courts interpret them differently, and the right answer depends on facts this page cannot know. Legacy Suite is not a law firm — before you sign or rely on anything, consult an attorney licensed in Hawaii.
