All lawyers who do personal injury work offer free initial consolations to potential clients. The purpose of the free consultation, from the lawyer’s perspective, is to gather information about the client and what happened to them in order to assess whether its a good case. The lawyer basically wants to evaluate whether the client has a viable claim that they can get compensation for.
The function of the initial consultation for the client is to provide an opportunity to get an expert legal opinion on the validity of their claims. It also gives them an opportunity to meet and get to know the attorney and decide whether or not to retain them or find someone else.
