Explain the essentials of partnership and distinguish it from joint Hindu family business.

Partnership, as Section 4 of the Indian Partnership Act, 1932 tells us, is "the relation between persons who have agreed to share the profits of a business carried on by all or any of them acting for all," and this single sentence conceals within it every essential that distinguishes a true partnership from a joint Hindu family business carrying on trade under the guidance of its karta.

The Essentials Drawn from Section 4

The definition, on close reading, resolves into three necessary elements, as the Supreme Court explained in CIT v. G. Parthasarthy Naidu: there must be persons who agree, a business carried on by all of them or by any of them acting for all, and an agreement to carry on that business and share its profits. It is worth walking through each in turn, because it is precisely on these essentials that partnership parts ways with the joint Hindu family.

Plurality of persons and a genuine agreement. At least two persons must come together, and their coming together must rest on contract, not on any other legal relation. Section 5 states this expressly: the relation of partnership arises from contract and not from status, and in particular, members of a Hindu undivided family carrying on a family business as such are not partners in that business merely by virtue of belonging to the family. The commentary explains the underlying logic — where a person becomes entitled to a share in family business merely because he was born or adopted into the family, that entitlement is a "family quasi-partnership created by operation of law," not a partnership born of contract. It follows that a firm as such, and equally a Hindu undivided family as such, cannot be a "person" capable of entering into partnership; the Supreme Court in Rashiklal & Co. v. CIT held that Section 4 speaks only of individuals, so that even where a karta or coparcener joins a partnership, he does so in his individual capacity, and his rights and obligations are governed by the Partnership Act, not by Hindu law.

Carrying on of a business. The agreement must relate to a business, broadly defined under Section 2(b) to include every trade, occupation and profession. Mere co-ownership of property, without more, is not business — a point Explanation 1 to Section 6 makes explicit, and one illustrated by the classical example of two co-owners of a house who simply divide rent between themselves; they are not partners because letting a house passively is not carrying on a business, though if they jointly ran it as a hotel for profit, they would become partners in that venture.

Agreement to share profits, and mutual agency. The business must be conducted with the object of sharing its profits, and — crucially — it must be carried on by all the partners or by any of them acting as agent for the rest. This mutual agency requirement is what the House of Lords tested in the celebrated case of Cox v. Hickman, where creditors supervising a debtor's business to recoup their dues from profits were held not to be partners, because the business was not being carried on on their behalf; the true test of partnership, Lord Wensleydale observed, is not mere participation in profits but whether the relation of principal and agent exists between the person taking profits and the person actually carrying on the business. Section 6 codifies this composite, fact-sensitive inquiry, directing that "regard shall be had to the real relation between the parties, as shown by all relevant facts taken together" — no single fact, including profit-sharing, being treated as conclusive.

Distinguishing Partnership from Joint Hindu Family Business

Having laid down these essentials, the commentary on Section 5 draws out five sharp points of difference between a partnership and a joint Hindu family carrying on business, and each difference traces directly back to the essentials just discussed.

The Bombay High Court's decision in Sakrabhai v. Maganlal is cited in the commentary as authority for two of these points — that a coparcener's liability is confined to his share of the joint family estate, and that within the family business all effective powers of management rest with the karta rather than being distributed through mutual agency among the members. Similarly, Samalbhai v. Someshwar is cited for the proposition that a coparcener, unlike a partner, cannot sue for an account of past profits and losses, precisely because his rights flow from status within the family rather than from a bargain struck between principals and agents. The Calcutta High Court decision in Udai Chand v. Than Singh reinforces the point at a structural level: two joint Hindu families cannot, as families, unite to form a partnership, though their respective managing members may certainly become partners in their individual capacities, each still owing separate duties to his own family.

Illustrations Testing the Essentials

The distinction becomes concrete once tested against recurring fact patterns that the commentary sets out under Sections 4 and 6. Where A and B jointly purchase 100 bales of cotton agreeing to sell them for their joint account, they are partners in respect of that cotton, since a business is genuinely being carried on for shared profit; but if they merely purchase the cotton agreeing to divide it between themselves, no business exists and they are not partners at all. Equally, where two doctors formed a partnership merely to treat patients jointly, that arrangement was treated as a business for partnership purposes, showing that "business" need not be commercial in the conventional sense.

By contrast, the family setting illustrates the opposite pole. Where a manager of a joint Hindu family enters into a contract of partnership with outsiders on behalf of the family business, that act alone does not make the other family members partners in the resulting firm — a principle affirmed by the Privy Council in Pichappa Chettiar v. Chockalingam Chettiar and by the Madras High Court in Gangayya v. Venkatramiah. This is entirely consistent with the essential requirement of an actual agreement between persons: the other family members never contracted with the outside party at all: their relationship to the family business rests on birth-status, not on any bargain of mutual agency that Section 4 demands.

Why the Distinction Matters in Practice

The practical stakes of this distinction are considerable, and they flow directly from the essentials examined above. Because a partnership is a creature of mutual agency and contract, every partner's personal estate remains exposed to the firm's creditors, and the death or insolvency of any partner can, absent a contrary agreement, bring the firm itself to an end under Sections 42 and 44. A coparcener in a joint family business enjoys no such personal exposure beyond his share, and the family business survives his death untouched, because it was never founded on the contractual, agency-based relationship that Section 4 requires. The Supreme Court's observation in Girdharbhai v. Saiyed Mohd. Kadri captures the underlying spirit of the entire inquiry: whether a genuine partnership exists is always a question to be answered by looking at the real relation between the parties as disclosed by all the facts taken together, precisely as Section 6 commands, rather than by resting on labels, family ties, or superficial arrangements for sharing income.
