A complete first file package helps an appraiser identify the open issues quickly.
Start with the assignment role, claim number, loss location, property type, date of loss, known deadlines, and current claim status. Then include the latest estimate, any prior estimates, labeled photos, reports, invoices, diagrams, and correspondence that explains the disputed items.
The most helpful summary is short and specific: what is agreed, what remains disputed, and what decision or next step is needed.
If the file may need an umpire, include both appraisers’ positions and any existing appraisal materials. If the file needs a claim review, include the documents that show how the current scope and pricing were developed.
