A very solid approach is to talk to friends and trusted persons in your community who have experienced a similar problem you face to get ideas about lawyers. Ask them who their lawyers were and how they rated the lawyer.
Lawyer referral services are another source of information. Many quality lawyer referral services exist to help you sort through all the basics about the lawyer. Those with the highest ratings that are offered can be a good place to start your specific search.
The best way to decide is by talking to the lawyer. The insight into the lawyer's approach can help you decide if the lawyer is right for you. Whether the lawyer is willing to spend a few hours to be your advisor may show you the lawyer will be aggressive in your case later on. Finally, don't make up your mind about hiring a lawyer until you've met him or her.
