You just fell and were injured. Does that mean it was someone else’s fault?

I agree with Mr. Meyer’s answer. People often time think that because they were injured, there has to be someone else responsible for the injury. When you hire a competent personal injury lawyer or law firm, you usually get years of experience that will help you determine if you have a viable claim. Your post and follow up raise a lot of questions. The pothole was in the parking lot. Walmart may not own the parking lot, but they probably have some duty to maintain it or report dangerous conditions, such as potholes to the actual owner. Also, you need to document the dangerous condition of the pothole as soon as possible. A diligent property owner will have the pothole filled in and then you will have a hard time trying represent what the condition was when you fell. Also, you bring up the lighting issue. You will need to have a slip and fall expert look at the condition at about the same time of night as your incident and determine with a light meter whether the lighting was adequate at the time. Your ability to have the condition investigated adequately will increase when you retain a competent attorney. I suggest you do that and the attorney or firm will determine whether in their opinion if you have a meritorious case that you can purse against Walmart.
