Hawaii Will Requirements at a Glance
Here are the exact rules for making a valid will in Hawaii:
| Minimum age to make a will | 18 |
| Witnesses required | 2 |
| Notarization required | NO — notarization is not required to make a Hawaii will legally valid. However, a notary is needed if the testator and witnesses choose to sign a self-proving affidavit under HRS 560:2-504, which speeds up probate by eliminating the need for witnesses to testify in court. |
| Handwritten (holographic) will allowed | YES with conditions — Hawaii recognizes holographic (handwritten) wills under HRS 560:2-502(b). A holographic will is valid without witnesses if the signature and material portions of the document are in the testator’s own handwriting. Typed or printed material provisions will not satisfy this requirement. |
| Self-proving affidavit available | YES — under HRS 560:2-504, a will may be made self-proving at the time of execution or at any later date. The testator and both witnesses must sign sworn affidavits before a notary public (or other officer authorized to administer oaths). A self-proving will is accepted by the court without requiring witness testimony, which may simplify and speed up probate. |
| Statutory will form | NO — Hawaii does not provide an official statutory fill-in-the-blank will form in its probate code. The Hawaii State Judiciary self-help portal offers general guidance and court forms for probate proceedings, but not a standardized will template. You may wish to check with the Hawaii courts self-help center or consult a licensed Hawaii attorney. |
What a Hawaii Will Does (and Doesn’t Do)
In Hawaii, a valid will may name a personal representative (executor) to manage the estate through probate, name a guardian for minor children, direct how probate assets are distributed among beneficiaries, create testamentary trusts, make specific gifts of property or cash, and designate alternate beneficiaries if a primary beneficiary predeceases the testator.
What a Hawaii will does NOT control: A Hawaii will does not control assets that pass outside of probate. These include life insurance proceeds with a named beneficiary, retirement accounts (401k, IRA) with a named beneficiary, payable-on-death (POD) or transfer-on-death (TOD) accounts, property held in joint tenancy with right of survivorship, assets held in a living trust, and property held as tenants by the entirety between spouses.
These assets pass directly to the named beneficiary or surviving co-owner regardless of what the will says.
Oral wills in Hawaii: NO — Hawaii’s Uniform Probate Code (HRS Chapter 560) requires a will to be “in writing” under HRS 560:2-502. Hawaii does not have a statute authorizing oral (nuncupative) wills. All valid wills must be written documents — either formally witnessed or holographic.
How to Update or Revoke a Hawaii Will
Under HRS 560:2-507, a Hawaii will may be updated by executing a codicil (a written amendment signed and witnessed with the same formalities as the original will) or revoked entirely by (1) executing a subsequent will that expressly revokes the prior will or is inconsistent with it, or (2) performing a revocatory act on the will such as burning, tearing, canceling, obliterating, or destroying it, with the intent to revoke.

Another person may perform the revocatory act if done in the testator’s conscious presence and at the testator’s direction.
Other Hawaii will-making rules: Hawaii recognizes reciprocal beneficiary relationships in its probate code. Under HRS 560:2-804, divorce, annulment, or termination of a reciprocal beneficiary relationship automatically revokes will provisions in favor of the former spouse or former reciprocal beneficiary, unless the will expressly states otherwise. This is unique to Hawaii and reflects the state’s recognition of reciprocal beneficiaries alongside traditional marital relationships.
Additionally, Hawaii adopted a version of the Uniform Probate Code (HRS Chapter 560), which allows informal probate (a simplified, non-court-hearing process) for uncontested estates.
Hawaii also recognizes the harmless error doctrine under HRS 560:2-503, which allows a court to validate a document as a will even if it does not fully comply with execution formalities, as long as clear and convincing evidence shows the testator intended it to be their will.

Understanding Hawaii Estate Planning
Getting started with Hawaii estate planning is the single best gift you can give your family. A valid Hawaii will lets you decide who inherits, name an executor, and name a guardian for your children — instead of leaving it to a default state formula.
When people look into Hawaii estate planning, the real answer comes down to the state’s execution rules: your age, the number of witnesses, and whether you make it self-proving. If any part of Hawaii estate planning is unclear, your state court’s self-help center can point you to the official forms and resources.
