Why Investigation Matters

A strong personal injury case begins with a thorough investigation. The value of your claim — and whether it succeeds at all — depends heavily on the evidence gathered. Attorneys often begin investigating before even meeting the client, acting quickly to preserve time-sensitive evidence.

Evidence Gathering

  • Accident scene photographs and video (including surveillance footage, which may be overwritten quickly)
  • Police and incident reports
  • Vehicle damage assessments
  • Electronic data (EDR/black box data from vehicles, GPS records)
  • Cell phone records (for distracted driving cases)
  • Social media monitoring of the defendant

Witness Investigation

Attorneys identify and interview witnesses early — memories fade and witnesses become unavailable over time. Witness statements are documented formally. In litigation, witnesses may be deposed. Expert witnesses are retained as needed: accident reconstruction experts, medical experts, engineering experts.

Records Investigation

  • Medical records subpoenas and review
  • Employment records for lost wage claims
  • Prior incident reports at the same location (for premises liability)
  • Corporate maintenance records (for commercial truck or equipment cases)
  • Prior claims or lawsuits against the same defendant

Preservation Letters

Attorneys send litigation hold or preservation letters early in the process, demanding that defendants preserve all relevant evidence — documents, surveillance footage, vehicle data, maintenance records. Failure to preserve evidence after a preservation demand can result in sanctions against the defendant.
