Keep an index with document dates and sources. Preserve originals and prepare the records; send requested materials according to the firm's instructions after initial review.

Commercial losses require a broader proof file
A residential property claim often focuses on repair cost and loss of use. A commercial claim may involve repair cost, tenant disruption, rent loss, business interruption, extra expense, financing pressure, code upgrades, equipment, build-out, access, and project delay.
Because the claim affects an asset and an income stream, the proof file needs to be broader.
Preserve the policy file and the repair file
Save the policy, declarations page, endorsements, claim correspondence, carrier estimate, payment history, reservation letters, denial letters, adjuster notes if available, and communications with the insurer.
Save contractor estimates, bids, invoices, mitigation records, engineering reports, architect notes, permits, code correspondence, schedules, change orders, photos, videos, and expert reports.
Do not separate tenant, accounting, and timeline proof
Commercial owners should preserve leases, rent rolls, tenant communications, abatements, concessions, vacancy records, default notices, relocation communications, and property-management records, along with profit-and-loss statements, tax returns, general ledgers, bank deposits, payroll records, sales reports, invoices, and prior-year comparisons.
A single timeline connecting the date of loss, inspections, mitigation, insurer positions, payments, repair decisions, permits, tenant impacts, and reopening can make the broader claim much easier to understand.
