Lawyers may be divided into several types. Trial lawyer is one type. Office-practice lawyer is another. Office- practice is concerned with matters such as preparing documents， advising business， or settling estates. Many office-practice lawyers never participate in a lawsuit， but leave litigation to trial lawyers. General practitioners， especially in small communities， may handle every matter that is brought to office. House counsels are another large group of attorneys. They are employed by business to assist in the internal operations of the business by preventing and solving legal problems.
Lawyers play important roles in society. First of all， they are advisors. A lawyer's product is advice - advice on an infinite variety of subjects. Much of the advice is not on legal matters， but may involve business decisions or family affairs. Second， lawyers are advocates for their clients. Office lawyers negotiating a contract are advocates just as trial lawyers are；their advocacy is directed at other attorneys and their clients， rather than to judges and juries. Third， lawyers are negotiators of compromise. They seek to avoid the difficulties and expenses of litigation by finding a mutually satisfactory alternative.
To be a good advisor， advocate and negotiator， lawyers must be cultured. They must be able to appreciate the historical relevance of our fundamental freedoms and the role of law in our society. They must be keenly aware of the world in which they live， what is right about it and what is wrong， so that they can fulfil their role as instrument of change. They must be compassionate and sensitive to human problems and weaknesses， because the practice of law is a very personal matter.
Lawyers must be courageous and willing to represent unpopular causes， because the right to counsel exists as a necessity. They must be willing not only to defend such causes， but to defend the system that requires such representation.
