While it’s not the only requirement, the injury needs to have been someone else’s fault, and caused by their negligence. Physically visible injuries are not necessary for a personal injury claim; attacks of defamation, emotional distress, or the expectation of harm would all be grounds for filing a personal injury lawsuit against that person. Another thing to consider is whether the injury created compensatory damages, such as medical expenses and bills or lost wages. If all of these things are true, then you have a personal injury case. It is recommended that you speak with one of our skilled Los Angeles injury lawyers immediately.
