A corporation is defined as a legal entity or structure created under the authority of the laws of a state, consisting of a person or group of persons who become shareholders. The entity’s existence is considered separate and distinct from that of its members.
Like a real person, a corporation can enter into contracts, sue and be sued, pay taxes separately from its owners, and do the other things necessary to conduct business. Since a corporation is an entity in its own right, it is liable for its own debts and obligations. As a result, providing that corporate formalities are followed, the corporation’s owners (the shareholders) enjoy limited liability, and are legally shielded from the corporation’s liabilities and debts.
The existence of a corporation is not dependent upon who the owners or investors are at any one time. Once formed, a corporation continues to exist as a separate entity, even when shareholders die or sell their shares. A corporation continues to exist until the shareholders decide to dissolve it or merge it with another business.
Corporations are subject to the laws of the state of incorporation, and to the laws of any other state in which the corporation conducts business. Corporations may thus be subject to the laws of more than one state. All states have corporation statutes that set forth the ground rules as to how corporations are formed and maintained. 
Nature of Corporations
A corporation, or body politic, or body incorporate, is a collection of many; individuals united in one body, under a special denomination, having perpetual succession under an artificial form, and vested by the policy of the law with a capacity of acting in several respects as an individual, particularly of taking and granting property, contracting obligations and of suing and being sued; of enjoying privileges and immunities in common and of exercising a variety of political rights, more or less extensive, according to the design of its institution or the powers conferred upon it, either at the time of its creation or at any subsequent period of its existence.
In the case of Dartmouth College against Woodward, 4 Wheat. Rep. 626, Chief Justice Marshall describes a corporation to be ‘an artificial being, invisible, intangible, and existing only in contemplation of law. Being the mere creature of law,’ continues the judge, ‘it possesses only those properties which the charter of its creation confers upon it, either expressly or as incidental to its very existence. These are such as are supposed best calculated to effect the object for which it was created. Among the most important are immortality, and if the expression may be allowed, individuality properties by which a perpetual succession of many persons are considered, as the same, and may act as the single individual, They enable a corporation to manage its own affairs, and to hold property without the perplexing intricacies, the hazardous and endless necessity of perpetual conveyance for the purpose of transmitting it from hand to hand. It is chiefly for the purpose of clothing bodies of men, in succession, with these qualities and capacities, that corporations were invented, and are in use.’
The words corporation and incorporation are frequently confounded, particularly in the old books. The distinction between them is, however, obvious; the one is the institution itself, the other the act by which the institution is created.
Corporations are divided into public and private.
Public corporations, which are also called political and sometimes municipal corporations, are those which have for their object the government of a portion of the state and although in such case it involves some private interests, yet, as it is endowed with a portion of political power, the term public has been deemed appropriate.
Another class of public corporations are those which are founded for public, not for political or municipal purposes, and the whole interest in which belongs to the government. The Bank of Philadelphia for example, if the whole stock belonged exclusively to the government, would be a public corporation; but inasmuch as there are other owners of the stock, it is a private corporation. 
Defining Features of a Corporation
A corporation has four defining characteristics that differentiate it from other business structures. It provides limited liability to its owner or owners, a feature not found in proprietorships and general partnerships. Its lifespan – unlike that of a limited liability company – is limitless. It is further defined by a centralized management and the capacity of its owners to feely transfer interests to others.
Limited Liability: Unlike proprietorship and partnership, a corporation is recognized as a separate and distinct entity from its owners. Its legal and financial obligations are of its own and are not the same with that of its owners. The owners are exposed to financial risks to the corporation only to the extent of their investment. In case a corporation goes bankrupt, creditors can only call on the company’s assets and not that of its owners. If it is sued, the suit is against the organization or the office of those responsible for it and not against the owner.
Indefinite Life: As a corporation is considered independent of its owners, its life does not depend on the ownership of a particular business entity or individual. Its owners could change as often as it wants, but the business continues until all of them agree to dissolve the company or merge it with another. Due to its unlimited lifespan, it is able to accumulate capital through the years to be used for future investments.
Transferability of Interest: A for-profit corporation is owned by people who have bought shares or interest in the company. Shareholders can sell their ownership or interest in it by selling their stocks. If there are no stockholders, the organization is a non-stock corporation, which may or may not operate for profit.
Centralized Management: A corporation usually has a board of directors elected by shareholders. The board makes important decisions for the company, hires officers, and sets company policies.

Certificate of incorporation
A certificate of incorporation is a legal document relating to the formation of a company or corporation. It is a license to form a corporation issued by state government. Its precise meaning depends upon the legal system in which it is used, but the two primary meanings are:
In English and Commonwealth legal systems, a certificate of incorporation is usually a simple certificate issued by the relevant government registry as confirmation of the due incorporation and valid existence of the company.
In other common law legal systems, the certificate of incorporation has less legal significance, although it has been held by the House of Lords in Cotman v Brougham  AC 514 that because the issue a certificate of incorporation is conclusive evidence of the formation of a company, the issuance of the certificate overrides any irregularities which may have occurred during the formation of the company.

A corporation enjoys the laws of the sovereign country just like a citizen, and often like any citizen, it has the choice of not following the laws, rather exercise it for its own good. Unlike a citizen, a corporation is harder to catch owing to their vast amount of resources. Because their existence is completely entangled in legal terminology, it is much harder to prove their crimes, although they can be spotted.
As a legal and individual entity, a corporation is subjected to a broad spectrum of laws as governed by the sovereign laws, and these laws have to be implemented properly for the corporation to abide by the power of laws.
