Step 1. Talk to the lawyer. The easiest way to learn how many cases a lawyer wins or loses is to talk to them. Some attorneys keep this kind of information and can tell you their history, white others may not. All lawyers will be able to tell you, in general, what their history is.
Many attorneys work locally, especially those who practice family law, civil law or criminal defense law. You can ask the attorney in what jurisdiction or courthouse most of their cases are heard, and then contact the state judicial offices or go to their websites.
