Corporate law (also „company“ or „corporations“ law) is the practice or study of how shareholders, directors, employees, creditors, and other stakeholders such as consumers, the community, and the environment interact with one another.

Corporate law is a part of a broader companies law (or law of business associations). Other types of business associations can include partnerships (in the UK governed by the Partnership Act 1890), or trusts (like a pension fund), or companies limited by guarantee (like some community organizations or charities).

Under law, corporations of all sizes have separate legal personality, with limited or unlimited liability for its shareholders. They control the company through a board of directors which, in turn, typically delegates control of the corporation’s day-to-day operations to a full-time executive.
