Most lawyers specializing in litigation belong to litigation law associations, and you can use this fact to your advantage as a way to track down potential attorneys. Litigation law associations are usually available on a state level, though some large cities have them too. Check the Internet for ones in your area.

A tried-and-tested way to do so is to consult with friends and family who have been in similar situations, as to ask for their opinions on the lawyers they used.
