Corporate law (also known as business law or enterprise law or sometimes company law) is the body of law governing the rights, relations, and conduct of persons, companies, organizations and businesses. It refers to the legal practice relating to, or the theory of corporations. Corporate law often describes the law relating to matters which derive directly from the life-cycle of a corporation. It thus encompasses the formation, funding, governance, and death of a corporation.

While the minute nature of corporate governance as personified by share ownership, capital market, and business culture rules differ, similar legal characteristics – and legal problems – exist across many jurisdictions. Corporate law regulates how corporations, investors, shareholders, directors, employees, creditors, and other stakeholders such as consumers, the community, and the environment interact with one another.Whilst the term company or business law is colloquially used interchangeably with corporate law, business law often refers to wider concepts of commercial law, that is, the law relating to commercial or business related activities. In some cases, this may include matters relating to corporate governance or financial law. When used as a substitute for corporate law, business law means the law relating to the business corporation(or business enterprises), i.e. capital raising (through equity or debt), company formation, registration, etc.
