What evidence do I need for a personal injury claim?

Useful evidence may include police or incident reports, photographs and video, witness information, medical records and bills, prescription records, wage documents, insurance policies, repair estimates, and correspondence with insurers. A clear timeline of the event, symptoms, treatment, missed work, and day-to-day limitations can also help connect the injury to its practical consequences.
Evidence can disappear quickly. Vehicles may be repaired, surveillance footage overwritten, electronic data deleted, and witnesses harder to find. Preserve original files and physical items, avoid editing photographs, and share all potentially relevant material with counsel—including facts that may seem unfavorable—so the legal team can assess it properly.
