Quick answer: the ordinary 5-6% realtor commission applies as usual, plus a reasonable personal representative fee with no fixed percentage, on top of a flat $100 filing fee. See how this plays out for your own numbers in the Hawaii probate real estate sale calculator.
Reasonable compensation for both roles
A wide range, depending on complexity
Attorney fees typically run $3,000 to $6,000 for informal probate, and $6,000 to $15,000 or more for formal, contested, or estate-tax-involved cases — a meaningful jump once a case leaves the simplest track.
One flat filing fee, regardless of track
The court filing fee is a flat $100 for both informal and formal proceedings, with publication costs typically adding $150 to $400 — a modest, predictable starting cost either way.
The state estate tax is the real cost driver for larger estates
Estates exceeding roughly $5.49 million (2026) face Hawaii's own state estate tax at rates of 10% to 20% on the excess, on top of any federal estate tax owed — a genuinely significant additional cost that most other states never impose.
A local probate attorney can review your estate — many offer a free consultation.
The §560:3-719 reasonableness standard and the $100 filing fee apply the same way across all of Hawaii's judicial circuits.
