To be able to do so, you should conduct your own background researches and determine whether a specific law firm is for real or not. You can checkout websites and forums about the law firms that you are considering, and try to analyze the information that you can get from these. Once you have analyzed them, you can now move on into making a preliminary decision. With the preliminary decision, you can try contacting the federal defense lawyer from the law firms that are on your short list. Ask questions and try to determine from their answers whether they are sincere or not.

When you are able to communicate with some of the people on your short list, it is not easier for you to pinpoint who are just there for business and who are there with the sincerest intentions to help. Use your research in making the right choice.
