Quick answer: No, Hawaii co-personal representatives don't automatically each collect their own full compensation with a combined total that grows by headcount. Co-personal representatives must agree on the division of the reasonable compensation available under HRS § 560:3-719, and the court will not increase the total simply because more than one personal representative served. Estimate the underlying reasonable range first with the Hawaii executor fee calculator.
One reasonable total, not one per person
The trustee exclusion doesn't change with headcount
If co-personal representatives can't agree, the court steps in
Because Hawaii's statute sets no default formula for splitting compensation between co-personal representatives, a disagreement over the division would go to the probate court, which would look at what each person actually contributed to the administration when deciding how to allocate the single reasonable total.
Self-determined fee review likely works the same way, per person
Real coordination costs, same as anywhere
Co-personal representatives in Hawaii share fiduciary duties, and disagreements about pace, priorities, or how to divide tasks can slow administration or invite disputes — a practical consideration independent of how compensation eventually gets divided.
Worked example
Two siblings serve as co-personal representatives of a Hawaii estate. One handles the bulk of the administrative work; the other contributes occasionally. A sole personal representative doing all the work might reasonably bill 40 hours at $40/hr, or $1,600.
| Co-personal representative | Hours | Rate | Compensation |
|---|---|---|---|
| Sibling A (primary administrator) | 32 hrs | $40/hr | $1,280 |
| Sibling B (occasional support) | 8 hrs | $40/hr | $320 |
Each figure reflects that person's own share of the single agreed-upon reasonable compensation, combining to roughly the same total a sole personal representative's full administration would have reasonably cost.
