Public-place injury: what evidence should I collect straight away?

If you are injured in a shop, venue, footpath, car park or other public/shared place, preserve evidence as early as you safely can: photos or video of the hazard and surrounding area, the exact location, witness details, incident-report information, medical records, receipts and evidence of lost income. Conditions can change quickly, so early evidence can be important. Guide: https://getinstantlaw.com/public-place-injuries
