A corollary of the rule of law is the existence of a legal profession sufficiently autonomous to be able to invoke the authority of the independent judiciary; the right to assistance of an advocate in a court proceeding emanates from this corollary—in England the function of barrister or advocate is distinguished from legal counselor (solicitor). As the European Court of Human Rights has stated, the law should be adequately accessible to everyone and people should be able to foresee how the law affects them.
In order to maintain professionalism, the practice of law is typically overseen by either a government or independent regulating body such as a bar association, bar council or law society. Modern lawyers achieve distinct professional identity through specified legal procedures (e.g. successfully passing a qualifying examination), are required by law to have a special qualification (a legal education earning the student a Bachelor of Laws, a Bachelor of Civil Law or a Juris Doctor degree), and are constituted in office by legal forms of appointment (being admitted to the bar). Most Muslim countries have developed similar rules about legal education and the legal profession, but some still allow lawyers with training in traditional Islamic law to practice law before personal status law courts. In China and other developing countries there are not sufficient professionally-trained people to staff the existing judicial systems, and, accordingly, formal standards are more relaxed.
Once accredited, a lawyer will often work in a law firm, in a chambers as a sole practitioner, in a government post or in a private corporation as an internal counsel. In addition a lawyer may become a legal researcher who provides on-demand legal research through a library, a commercial service or through freelance work. Many people trained in law put their skills to use outside the legal field entirely.
Significant to the practice of law in the common law tradition is the legal research to determine the current state of the law. This usually entails exploring case-law reports, legal periodicals and legislation. Law practice also involves drafting documents such as court pleadings, persuasive briefs, contracts, or wills and trusts. Negotiation and dispute resolution skills (including ADR techniques) are also important to legal practice, depending on the field.
