Quick answer: No, Connecticut co-fiduciaries don't split a fee according to any set formula — because there's no fee statute in Connecticut at all, there's no numbered multi-fiduciary subsection either. The Probate Court applies the same Hayward v. Plant reasonableness standard and Rule 39.2 nine-factor task statement to what each co-fiduciary actually contributed.

What a Probate Court would likely weigh
Because Rule 39.2's factors include the responsibilities involved, the character of work required, and the time required, a Connecticut probate judge reviewing co-fiduciary compensation would naturally look at how the administrative work was actually divided between the people serving — not an automatic even split, and not a separate full award for each person regardless of their actual contribution.
Real coordination costs, same as anywhere
Co-fiduciaries in Connecticut 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 approved.
Worked example
Two siblings serve as co-fiduciaries of a Connecticut estate. One handles the bulk of the administrative work; the other contributes occasionally. A sole fiduciary doing all the work might reasonably bill 40 hours at $40/hr, or $1,600.
| Co-fiduciary | 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 documented contribution against the Rule 39.2 factors, combining to roughly the same total a sole fiduciary's full administration would have reasonably cost.
