Professional associations and regulation

Mandatory licensing and membership in professional organizations

In some jurisdictions, either the judiciary or the Ministry of Justice directly supervises the admission, licensing, and regulation of lawyers.

Other jurisdictions, by statute, tradition, or court order, have granted such powers to a professional association which all lawyers must belong to. In the U.S., such associations are known as mandatory, integrated, or unified bar associations. In the Commonwealth of Nations, similar organizations are known as Inns of Court, bar councils or law societies. In civil law countries, comparable organizations are known as Orders of Advocates, Chambers of Advocates, Colleges of Advocates, Faculties of Advocates, or similar names. Generally, a nonmember caught practicing law may be liable for the crime of unauthorized practice of law.

In common law countries with divided legal professions, barristers traditionally belong to the bar council (or an Inn of Court) and solicitors belong to the law society. In the English-speaking world, the largest mandatory professional association of lawyers is the State Bar of California, with 200,000 members.

Some countries admit and regulate lawyers at the national level, so that a lawyer, once licensed, can argue cases in any court in the land. This is common in small countries like New Zealand, Japan, and Belgium. Others, especially those with federal governments, tend to regulate lawyers at the state or provincial level; this is the case in the United States, Canada, Australia, and Switzerland, to name a few. Brazil is the most well-known federal government that regulates lawyers at the national level.

Some countries, like Italy, regulate lawyers at the regional level, and a few, like Belgium, even regulate them at the local level (that is, they are licensed and regulated by the local equivalent of bar associations but can advocate in courts nationwide). In Germany, lawyers are admitted to regional bars and may appear for clients before all courts nationwide with the exception of the Federal Court of Justice of Germany (Bundesgerichthof or BGH); oddly, securing admission to the BGH's bar limits a lawyer's practice solely to the supreme federal courts and the Federal Constitutional Court of Germany.

Generally, geographic limitations can be troublesome for a lawyer who discovers that his client's cause requires him to litigate in a court beyond the normal geographic scope of his license. Although most courts have special pro hac vice rules for such occasions, the lawyer will still have to deal with a different set of professional responsibility rules, as well as the possibility of other differences in substantive and procedural law.

Some countries grant licenses to non-resident lawyers, who may then appear regularly on behalf of foreign clients. Others require all lawyers to live in the jurisdiction or to even hold national citizenship as a prerequisite for receiving a license to practice. But the trend in industrialized countries since the 1970s has been to abolish citizenship and residency restrictions. For example, the Supreme Court of Canada struck down a citizenship requirement on equality rights grounds in 1989, and similarly, American citizenship and residency requirements were struck down as unconstitutional by the U.S. Supreme Court in 1973 and 1985, respectively. The European Court of Justice made similar decisions in 1974 and 1977 striking down citizenship restrictions in Belgium and France.
