Frequently Asked Questions

Probate in Hawaii uses reasonable compensation for attorney fees, typically 2.3-3.6% of the estate value — about $28,731 all-in on a $500,000 estate. Estates under $100,000 may qualify for Affidavit for Collection of Personal Property.

Simple estates in Hawaii typically take 6-9 months through probate. Complex or contested estates can take 1-3 years. A revocable trust avoids probate entirely.

Hawaii has adopted the Uniform Trust Code and does not require witnesses for trust execution. Notarization is not required for validity, though many financial institutions require notarized trust documents. The successor trustee can publish Hawaii's optional creditor notice to shorten the claim window to 4 months; without it, the settlor's creditors have up to 18 months to bring a claim.

Hawaii offers remote online notarization (RON) for estate planning documents and transfer-on-death deeds to pass real estate without probate. These tools, combined with revocable trusts and beneficiary designations, provide multiple ways to transfer assets without probate.

A healthcare power of attorney in Hawaii requires 2 witnesses or notarization to be valid. A financial power of attorney requires no witnesses or notarization. A financial power of attorney is durable by default, so it stays in effect if you become incapacitated.

In Hawaii, the executor must file an inventory of the estate's assets within 90 days of appointment. A revocable trust skips the court-supervised inventory entirely, so a trustee distributes assets without filing one.

In Hawaii, divorce automatically revokes a beneficiary designation that names a former spouse on covered accounts, so the asset does not pass to the ex-spouse unless the designation is renewed after the divorce.

Estate Planning in Hawaii

Estate planning in Hawaii is shaped by remote online notarization and transfer-on-death deeds. The choice between a will and a revocable trust depends on which of those features changes the cost or process for your situation, not on any single rule.

Probate in Hawaii runs attorney fees on a reasonable-compensation standard, typically 2.3-3.6% of the estate value, with room to negotiate. A simple estate typically closes in 6-9 months, and the 4-month creditor-claim window sets the floor. Estates under $100K can use the Affidavit for Collection of Personal Property and avoid full probate administration. The Affidavit for Collection of Personal Property is presented directly to the bank, employer, or other holder of the property — it is not filed with a court.

For a revocable trust, Hawaii does not require witnesses for trust execution. Notarization isn't required for validity, though banks and title companies typically expect a notarized trust before they'll work with it. Hawaii has adopted the Uniform Trust Code, so trust administration follows the same baseline rules used in most states.

Hawaii offers transfer-on-death deeds, which move real estate to a named beneficiary at death without probate and remote online notarization for estate documents, so signing can happen over secure video. Combined with beneficiary designations on retirement accounts and payable-on-death registrations, these can move significant value outside probate without setting up a trust.
