If you believe surveillance video captured footage of your accident, inform your car accident attorney as soon as possible. Software often overwrites these videos in a short time, and your attorney will need to file a motion in court to ensure that this video evidence is secure and available to use when building your case. Your lawyer can also ask neighboring businesses and residents if they had surveillance cameras at the time of the accident. Again, if you locate individuals or entities with video evidence, let your attorney know so they can obtain and preserve the evidence as soon as possible.
