Appraisal Umpire
The neutral third party appointed to break a tie when the two party-appointed appraisers in an [[concept-appraisal-clause|appraisal clause]] proceeding can't agree on the amount of loss. The umpire's decision, combined with either appraiser's, becomes the final, binding award.
Why it matters
Umpire selection is where appraisal actually gets decided in practice. Each side's appraiser is expected to advocate somewhat for the side that appointed them, so the umpire is the only genuinely neutral decision-maker in the room.
On a real project
The two appraisers on a disputed claim each submit a list of umpire candidates, then a judge appoints one from the overlap, or by lot if there's no overlap at all, once it's clear the appraisers can't agree between themselves.
Who this matters most to
A Public Adjuster serving as a policyholder's appointed appraiser has a direct stake in who gets selected as umpire, since that person's number is what actually settles a deadlocked claim.
Where this goes wrong
Both sides' appraisers pick umpire candidates who lean toward the insurance industry's usual way of valuing claims, producing a "neutral" umpire who reliably sides with the carrier on close calls. A policyholder's attorney has to challenge the umpire selection process itself before the resulting appraisal award can be trusted as genuinely neutral.
