A lawyer is a person learned in the law and a person licensed to practice law. Law is the system of rules of conduct established by the sovereign government of a society to correct wrongs, maintain stability, and deliver justice. 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 retain lawyers to perform legal services. The role of the lawyer varies significantly across legal jurisdictions. Often, lawyers brief a court in writing on the issues in a case before the issues can be orally argued. They may have to perform extensive research into relevant facts and law while drafting legal papers and preparing for oral argument. Lawyers are always free to form voluntary associations of their own, apart from any licensing or mandatory membership that may be required by the laws of their jurisdiction. Like their mandatory counterparts, such organizations may exist at all geographic levels.

Practice of Law

In its most general sense, the practice of law involves giving legal advice to clients, drafting legal documents for clients, and representing clients in legal negotiations and court proceedings such as lawsuits, and is applied to the professional services of a lawyer or attorney at law, barrister, solicitor, or civil law notary. However, there is a substantial amount of overlap between the practice of law and various other professions where clients are represented by agents. These professions include real estate, banking, accounting, and insurance. Moreover, a growing number of legal document assistants LDAs are offering services which have traditionally been offered only by lawyers and their employee paralegals. Many documents may now be created by computer-assisted drafting libraries, where the clients are asked a series of questions posed by the software in order to construct the legal documents.

In the United States, the practice of law is conditioned upon admission to practice of law, and specifically admission to the bar of a particular state or other territorial jurisdiction. The American Bar Association and the American Law Institute are among the organizations that are concerned with the interests of lawyers as a profession and the promulgation of uniform standards of professionalism and ethics, but regulation of the practice of law is left to the individual states, and their definitions vary.

In the United States, the rules of professional conduct generally prohibit an attorney from assisting a non-attorney from engaging in the unauthorized practice of law. An attorney therefore may not partner with or split fees with a non-attorney in the performance of any sort of legal work. Furthermore, an attorney may not employ a disbarred or suspended attorney in a legal practice where former clients of the disbarred or suspended attorney will be represented.
