Meaning and Definition of a Joint Stock Company

A joint stock company is one of the most important forms of business organisation in the modern economy, especially where a business needs very large amounts of capital that a single owner or a small group of partners cannot supply on their own. Unlike a sole proprietorship or a partnership, a joint stock company is not identified with the individuals who own it. In the eyes of law it is treated as a distinct "person" of its own, separate from the members who have invested in it.

The Companies Act, 2013 is the principal law governing companies in India today, and it defines a "company" in Section 2(20) as a company incorporated under this Act or under any of the earlier Companies Acts. In practical terms this means a company comes into existence only when it is registered ("incorporated") with the Registrar of Companies (ROC) in the manner the Act lays down. A business does not become a company merely because it is large, or because many people have put money into it — it must go through the formal legal process of incorporation.

Company-law writers commonly describe a joint stock company as an artificial person, invisible and intangible, existing only in the eyes of law, brought into being by a process of law, having a perpetual succession and (traditionally) a common seal, with its capital divided into small, transferable units called shares, and its members enjoying limited liability. Each of these ideas — artificial person, created by law, perpetual succession, limited liability, transferable shares — is examined as a separate feature in the next section.

A note on how this fits with what CBSE/NCERT students study. Tamil Nadu's Higher Secondary Commerce syllabus studies the joint stock company on the same statutory foundation — the Companies Act, 2013 — that CBSE/NCERT Business Studies students also study when they learn about "company" as a form of business organisation. The underlying legal principles (separate legal personality, limited liability, incorporation by registration) are common to company law right across India; only the way the two syllabi sequence and present the topic differs.
