The distinguishing features of a corporation are (1) in order to be a corporation, a business enterprise must obtain a charter from the government. (A "charter" is a legal document that gives the corporation the right to exist and conduct business. Other types of business enterprises, such as sole proprietorship and a partnership, do not require a charter.); and (2) a corporation is considered to be a separate legal entity, and possesses rights and responsibilities which are distinct from those of its stockholders (owners).
