Types of Evidence Required for Insurance Claim Complaints
Strong evidence directly refutes insurer reasons like "experimental" treatments or policy exclusions. In 2023, 37% out-of-network health claims were denied--arm yourself accordingly.
Photographic and Video Proof
Timestamped photos/videos are unimpeachable for property/auto claims. Use apps like PHOTO iD for cloud-stored, tagged images compliant with audits. Dashcam/security footage proves liability (e.g., green light entry). Act fast--security overwrites in 24-72 hours; send preservation letters.
Mini Case: Homeowner's video inspection during COVID showed extensive damage; adjuster lowballed at $200k, overturned via independent appraisal at $350k.
Witness Statements
Include full name, address, contact, date. State facts: "I did not hear a turn signal" not "Driver didn't signal." Avoid "I think" to maintain credibility. Eyewitnesses validate liability in auto disputes.
How-To: Witness saw speed/conditions; notarize for weight.
Medical Records and Expert Reports
Critical for health/property claims linking incident to damages. Include FCEs (objective work capacity tests) and physician letters refuting denials. Personal statements detail daily impacts.
Example: Unum disability denial overturned with FCE proving inability to work.
Receipts, Invoices, and Timeline Documentation
Prove costs and sequence. Log dates of incident, reports, adjuster contacts to fight bad faith delays.
Digital Evidence
Admissible if authentic (eIDAS eSignatures, chain-of-custody). Caution: Social media can undermine claims. Use certified emails.
