Quick answer: No, Idaho co-personal representatives don't automatically each collect their own full compensation with a combined total that grows by headcount. Idaho Code § 15-3-719 contains no separate provision for multiple personal representatives — the same "reasonable compensation" standard governs, and the value of each co-personal representative's actual hours determines what they're individually owed. Estimate the underlying reasonable range first with the Idaho executor fee calculator.
No statutory split, because there's no statutory schedule to split
The reported hourly rate is about hours worked, not headcount
Because the roughly $25/hr non-professional figure reported by a practicing Idaho attorney reflects what's reasonable for actual work performed, it would logically apply to each co-personal representative's own documented hours — not get inflated because more than one person is serving. Two co-personal representatives splitting the same workload wouldn't reasonably expect double the total pay for the same underlying administration.
Excessive-compensation review likely works the same way
Each co-personal representative's work is assessed on its own
Because reasonableness under § 15-3-719 turns on the value of services actually rendered, a court dividing compensation among co-personal representatives (in a contested case) would naturally look at what each person individually contributed — not an automatic even split, and not a separate full fee multiplied by however many people are serving.
Real coordination costs, same as anywhere
Co-personal representatives in Idaho 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 assessed.
Worked example
Two siblings serve as co-personal representatives of an Idaho 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 a reported $25/hr non-professional rate, or $1,000.
| Co-personal representative | Hours | Rate | Compensation |
|---|---|---|---|
| Sibling A (primary administrator) | 32 hrs | $25/hr | $800 |
| Sibling B (occasional support) | 8 hrs | $25/hr | $200 |
Each figure reflects that person's own reasonable compensation for their own time, combining to roughly the same total a sole personal representative's full administration would have reasonably cost.
