Before you start looking for really good lawyers, you must know that lawyers have specific specializations. This means that not all lawyers are good at every facet of the law. Some lawyers are good at transactional stuff like helping you with wills but aren't as good in the litigation process (the actual courtroom presentation). Some lawyers can be good at negotiations and yet they fail at helping you sue companies for job discriminations and such. The best thing that you can do, then, is to know which kind of lawyer (or lawyers, if you can afford them) you're going to hire so that they can help you with a specific problem. Get educated with the various kinds of attorneys by going online and researching what sort will fit your case.

Background Check
Double Check
If you think that you're satisfied with enough of the information, don't just jump in and hire the person just yet. You need to do a double check on his or her credentials and scrutinize for specific things that may hurt your case. It might not be likely, but when it comes to your legal issues, there's no such thing as being too careful. Request to have the names of his or her past clients so you can contact them yourself and ask what the experience was like. Don't hesitate to do this because these are your legal rights you're talking about. It's always a good idea to have insight and outside perspective as to what kind of person you're going to work with.
So there you have it. Those are the basics on how to check the credentials of a lawyer. As a final tip on how to check for their credentials, make notes of what kind of professional associations the person is associated with as well as organizations he or she's involved in so you'll know if the person is just right for your case. All credentials must be checked and rechecked so you can absolutely assure yourself that this is exactly the kind of person you want to represent and advice you in court.
