Wiki article on this topic: A lawyer or attorney is a person who practices law, as an advocate, attorney, attorney at law, barrister, barrister-at-law, bar-at-law, civil law notary, counsel, counselor, counsellor, counselor at law, solicitor, chartered legal executive, or public servant preparing, interpreting and applying law, but not as a paralegal or charter executive secretary. Working as a lawyer involves the practical application of abstract legal theories and knowledge to solve specific individualized problems, or to advance the interests of those who hire lawyers to perform legal services.
The role of the lawyer varies greatly across legal jurisdictions, and so it can be treated here in only the most general terms.
In practice, legal jurisdictions exercise their right to determine who is recognized as being a lawyer. As a result, the meaning of the term "lawyer" may vary from place to place. Some jurisdictions have two types of lawyers, barristers and solicitors, whilst others fuse the two. A barrister is a lawyer who specialises in higher court appearances. A solicitor is a lawyer who is trained to prepare cases and give advice on legal subjects and can represent people in lower courts. Both barristers and solicitors have gone through law school, completed the requisite practical training. However, in jurisdictions where there is a split-profession, only barristers are admitted as members of their respective bar association.
In most countries, particularly civil law countries, there has been a tradition of giving many legal tasks to a variety of civil law notaries, clerks, and scriveners. These countries do not have "lawyers" in the American sense, insofar as that term refers to a single type of general-purpose legal services provider; rather, their legal professions consist of a large number of different kinds of law-trained persons, known as jurists, some of whom are advocates who are licensed to practice in the courts. It is difficult to formulate accurate generalizations that cover all the countries with multiple legal professions, because each country has traditionally had its own peculiar method of dividing up legal work among all its different types of legal professionals.
