A corporation or body corporate is an individual or a group of people, such as an association or company, that has been authorized by the state to act as a single entity (a legal entity recognized by private and public law as "born out of statute"; a legal person in a legal context) and recognized as such in law for certain purposes. Early incorporated entities were established by charter (i.e., by an ad hoc act granted by a monarch or passed by a parliament or legislature). Most jurisdictions now allow the creation of new corporations through registration. Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered based on two aspects: whether they can issue stock, or whether they are formed to make a profit. Depending on the number of owners, a corporation can be classified as aggregate (the subject of this article) or sole (a legal entity consisting of a single incorporated office occupied by a single natural person).
Registered corporations have a legal personality recognized by local authorities and their shares are owned by shareholders, whose liability is generally limited to their investment. One of the attractive early advantages corporations offered to their investors, compared to earlier business entities like sole proprietorships and joint partnerships, was limited liability. Limited liability separates control of a company from ownership and means that a passive shareholder in a corporation will not be personally liable either for contractually agreed obligations of the corporation, or for torts (involuntary harms) committed by the corporation against a third party (acts done by the controllers of the corporation).
