Quick answer: No, South Dakota co-personal representatives don't each collect a separate tiered commission with a combined total that grows by headcount. SDCL § 29A-3-719(c) computes the default commission on the estate's personal property, not on a per-person basis — so the single computed amount applies to the administration as a whole, however many people serve. Estimate the underlying default schedule first with the South Dakota executor fee calculator.
One computation, because the base is the estate, not the person
The seven reasonable-compensation factors point toward individual assessment
When subsection (a)'s reasonable-compensation standard applies instead of the tiered schedule — for example, when a will sets compensation and no renunciation is filed — several of its seven factors are inherently about the individual: the time and labor involved, the preclusion of other employment, and the person's experience, reputation, diligence, and ability can't sensibly be applied to a group as a single unit. A court weighing these for co-personal representatives would naturally look at what each individual actually contributed.
Real property compensation would likely follow the same logic
Real coordination costs, same as anywhere
Co-personal representatives in South Dakota 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 South Dakota estate with $500,000 in personal property, producing a $12,585 commission under § 29A-3-719(c) for a sole personal representative.
| Co-personal representative | Share of work | Illustrative compensation |
|---|---|---|
| Sibling A (primary administrator) | 80% | $10,068 |
| Sibling B (occasional support) | 20% | $2,517 |
Illustrative only — South Dakota's statute doesn't specify how to split the computed amount between co-personal representatives; the court decides based on each person's actual contribution, up to the combined $12,585 total.
