Law is a discipline that deals with the customs, rules and practices that people recognise as binding on them. It aims to give people the ability to exercise control over their own lives.
Several different branches of law are found in many societies, each of which has its own unique set of laws. These laws may deal with contracts, property, or other issues that affect individuals’ rights and responsibilities.
Contract law regulates the way people exchange goods and services, such as a bus ticket or trading options on a stock market. It also covers the legal rights and obligations of individuals, including their right to privacy, and to be treated equally by others.
Property law, which deals with people’s possessions, varies widely across countries. It covers all kinds of property, from real estate to personal possessions and intangible items such as bank accounts.
It is a field of academic study that draws on a number of disciplines. It is distinguished from empirical science in that it is prescriptive rather than descriptive, and from social science in that it is governed by norms.
The practice of law involves lawyers who advise and represent clients in court. Lawyers are usually members of a bar association or other independent regulating body such as a law society or a law firm, and are required to adhere to a specific legal code in order to maintain their professional identity.
They are often required to pass a qualifying exam, and are generally constituted in office by a legal form of appointment (being admitted to the bar). In some jurisdictions they are entitled to a title of respect such as Esquire or Doctor of Laws.
In the United States, lawyers must earn a law degree to be admitted to practice, or be certified as a specialist in a particular area of law. This is usually achieved through passing a qualifying examination or an approved course of studies.
A law degree typically includes a combination of theoretical and practical training. Some law schools also provide internships for students who want to gain hands-on experience before they enter practice.
The practice of law is governed by statutes, rules of the Supreme Court, and other statutory authorities. These laws define the basic functions of courts and other agencies of government, as well as procedures for deciding disputes between individuals or groups.
These laws are also used to impose and enforce coercive regulations. In the United States, for example, laws protect citizens from discrimination, and regulate public behavior and activities such as censorship.
They also help to ensure that the public is served with a fair and impartial process in all cases. This is a crucial feature of the rule of law.
Besides the laws of the individual country, law also regulates interactions between nations. For example, a nation’s foreign policy is shaped by its legal system, as well as its economics and politics.
Law can serve a wide range of purposes in society, from keeping the peace and maintaining the status quo to preserving individual rights, protecting minorities against majorities, promoting social justice, and providing for orderly social change. Some legal systems do a better job of serving these purposes than others.
