Quick answer: No, Massachusetts co-personal representatives don't automatically each collect their own full compensation with a combined total that grows by headcount. M.G.L. c.190B, § 3-719 contains no separate provision for multiple personal representatives — the same "reasonable compensation" standard and the McMahon v. Krapf factors govern, and the value of each co-personal representative's actual services determines what they're individually owed. Estimate the underlying reasonable range first with the Massachusetts executor fee calculator.
No statutory split, because there's no statutory schedule to split
Each co-personal representative's work gets its own McMahon v. Krapf analysis
Because reasonableness under § 3-719 turns on the McMahon v. Krapf factors — size of the estate, marketable nature of the assets, factual and legal complexity, time reasonably required, skill and ability employed, customary pay for similar work, and results accomplished — a court dividing compensation among co-personal representatives would naturally look at what each person individually contributed to those factors, not an automatic even split, and not a separate full fee multiplied by however many people are serving.
Misconduct by one doesn't necessarily cost the other
Real coordination costs, same as anywhere
Co-personal representatives in Massachusetts 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 Massachusetts 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 McMahon v. Krapf-reasonable compensation for their own time, combining to roughly the same total a sole personal representative's full administration would have reasonably cost.
