Quick answer: Arizona doesn't work like states with a percentage-of-estate commission, so there's no single pool for co-personal representatives to divide. Because A.R.S. § 14-3719 ties compensation to each person's own actual, reasonable hours, each co-personal representative is separately entitled to reasonable compensation for the work they personally performed — evaluated on their own hours, skill, and rate, not a percentage split of one total. Estimate one person's share first with the Arizona executor fee calculator.
Why there's no pool to split
One real limit: no double-billing the same event
Unequal contributions are normal, and expected
Because each co-personal representative's compensation tracks their own actual hours, it's entirely ordinary for one to end up with meaningfully more than the other — there's no assumption of an even split the way there might be with a percentage pool. A co-personal representative who did the bulk of the paperwork, asset marshaling, and court filings should reasonably bill more hours than one who mainly co-signed documents.
This differs from percentage-based states
In Georgia, North Carolina, and Ohio, the statute (or court practice) sizes one commission for the estate and then apportions it among co-executors by services rendered. Arizona skips that step entirely — there's no total to apportion, because compensation was never a percentage of the estate to begin with. The practical result is similar (more work generally means more pay), but the mechanism is different: division of a shared pool versus independent evaluation of each person's own hours.
Worked example
Two siblings serve as co-personal representatives of an Arizona estate. One handles most of the administrative work; the other contributes occasionally.
| Co-personal representative | Hours | Rate | Compensation |
|---|---|---|---|
| Sibling A (primary administrator) | 60 hrs | $40/hr | $2,400 |
| Sibling B (occasional support) | 10 hrs | $40/hr | $400 |
Each figure is independently reasonable compensation for that person's own hours — there's no combined "total pool" being split 6-to-1; both amounts are simply what each sibling separately earned.
