Law is the set of rules that regulate behavior in a social or governmental organization. These rules are usually created by legislators and enforced by courts. It is an intangible but important concept that has been variously described as a science and an art of justice.

The law is a system of rules that governs the conduct of people and institutions, often based on common beliefs and principles. Generally, it is applied evenly and fairly and ensures rights and protection of individuals as well as property and contract.

Generally, there are two types of legal systems: civil and common law. The first is influenced by ancient and medieval sources, and is used in Europe and America, while the latter has more modern sources and is used in Asia and Africa.

A third type of law is religious law, based on scriptures. This is used in countries where religion and state are not separate entities, such as China and some African states.

Law includes the law of contracts, torts, property, immigration and nationality, and eminent domain. It also covers the rules of evidence, procedure in court and bankruptcy.

A lawyer is a person who provides legal advice and services to clients on issues involving the law. They are professionals who are licensed by the government to practice and have special qualifications such as a law degree, a legal qualification or a Bar Professional Training Course.
