A lawyer friend of mine has devoted herself to the service of humanity. Her special area i

s called "public interest law". Many other lawyers represent only clients who can pay high fees. All lawyers have had expressive and highly specialized training, and they work long, difficult hours for the money they earn. But what happens to people who need legal help and can not afford to pay these lawyers' fee？

Public interest lawyers fill this need. Patricia, like other public interest lawyers, earns a salary much below what some lawyers can earn. Because she is willing to take less money, her clients have the help they need, even if they can pay nothing at all.

Some clients need legal help because stores have cheated them with faulty merchandise. Others are in unsafe apartments, or are threatened with eviction (being driven) and have no place to go. Their cases are all called " civil" cases. Still others are accused of criminal acts, and seek those public interest lawyers who handle "criminal" cases. These are just a few of the many situations in which the men and women who are public interest lawyers serve to extend justice throughout society.
