Distinguish between Mitakshara coparcenary and Dayabhaga coparcenary.

The Mitakshara and Dayabhaga schools represent two fundamentally different philosophical approaches to the nature of family, property, and the bond between the individual and the ancestral estate. As the Supreme Court rightly observed in Commissioner of Wealth Tax v. Bishwanath Chatterjee (AIR 1976 SC 1492), while the essence of a Mitakshara coparcenary is unity of ownership, the essence of a Dayabhaga coparcenary is unity of possession — and this single distinction radiates outward into virtually every aspect of the two systems.

Geographical Application

The Mitakshara school, as expounded by Vijnaneshwara in his commentary on the Yajnavalkya Smriti, prevails across almost all of India — covering the states of Andhra Pradesh, Karnataka, Tamil Nadu, Maharashtra, Gujarat, Rajasthan, Uttar Pradesh, Punjab, and others. The Dayabhaga school, founded by Jimutavahana, operates primarily in Bengal and parts of Bihar and Orissa. This geographical divide is not merely academic — it has governed property law, succession, and family rights of millions of Hindus for centuries.

Foundation and Commencement

The most fundamental difference between the two schools lies in the event that triggers the formation of a coparcenary. Under Mitakshara, the birth of a son is the starting point of the coparcenary. The moment a son is born to a man who holds ancestral property, a coparcenary springs into existence between them by the pure operation of law. Under Dayabhaga, on the other hand, the death of the father is the starting point. So long as the father lives, he is the sole and absolute owner of his property — ancestral and self-acquired alike — and the sons have no interest whatsoever in it during his lifetime. It is only when the father dies leaving two or more sons that a coparcenary first comes into being. Consequently, under Dayabhaga, there can never be a coparcenary between a father and his sons, or between a grandfather and his grandsons — only between brothers, uncles and nephews, or cousins who inherit together.

Right by Birth vs. Right by Succession

This is perhaps the most consequential distinction of all. Under Mitakshara, the son acquires an interest in the coparcenary property by birth — an interest that arises the very instant he is born, without any act of the parties and indeed even before birth, at the stage of conception. This interest is described in the texts as apratibandha daya — unobstructed heritage — because the existence of the father is no obstruction to its accrual. The son is a co-owner with his father from the moment he enters the world.

Under Dayabhaga, no such right exists. All heritage is sapratibandha daya — obstructed heritage — because the right to inherit arises only when the owner dies. The sons have, during their father's lifetime, nothing more than a spes successionis, a bare chance of succession contingent on surviving the father. Dayabhaga does not recognize the concept of unobstructed heritage at all. The implication is profound: a Dayabhaga father can sell, gift, mortgage, or will away his property — ancestral or self-acquired — in any manner he pleases during his lifetime, and the sons are powerless to object. A Mitakshara father, by contrast, cannot alienate the ancestral property arbitrarily because the sons already have a vested interest in it by birth, and their presence acts as a legal restraint on his powers of alienation.

Nature of Interest: Fluctuating vs. Fixed

In a Mitakshara coparcenary, since every coparcener takes by birth, the interest of each coparcener is fluctuating and uncertain — it expands when a coparcener dies and contracts when a new one is born — and no one can claim a definite fractional share until an actual partition is demanded. In a Dayabhaga coparcenary, since the coparcenary is formed only on the father's death, each son immediately takes a fixed, defined, and determinate share in the property. If the father dies leaving three sons, each son at once becomes the owner of an ascertained one-third, and that share does not fluctuate with births or deaths in the family.

Doctrine of Survivorship

One of the most significant practical consequences flows from the above distinction. Under Mitakshara, when a coparcener dies, his undivided interest passes to the surviving coparceners by the doctrine of survivorship (jus accrescendi). He leaves nothing for his heirs — his wife, daughters, and female dependants receive no share from the coparcenary by way of inheritance, only maintenance. This classical position has been substantially modified by Section 6 of the Hindu Succession Act, 1956, as amended in 2005.

Under Dayabhaga, the doctrine of survivorship has no application whatsoever. Since every coparcener holds a defined share, that share, on his death, passes by succession to his heirs — his widow, daughters, and others in the order of inheritance. This is why, under Dayabhaga, a widow or daughter of a deceased coparcener could step into his shoes and become a coparcener alongside the surviving brothers of the deceased — a result that was altogether impossible under classical Mitakshara law, where no female could ever be a coparcener with male members.

Position of Females

Under classical Mitakshara, no female could be a coparcener under any circumstances. A wife, a widow, a mother — none of them could hold the status of a coparcener. The Hindu Succession (Amendment) Act, 2005 has changed this by conferring coparcenary rights upon daughters by birth.

Under Dayabhaga, since property devolves by succession and each coparcener's share passes to his heirs, a widow or daughter could become a coparcener by representing the share of the deceased coparcener. Thus a Dayabhaga coparcenary could consist of both males and females. However, a coparcenary under Dayabhaga could not start with females — if a man died leaving only female heirs, they succeeded to the property but did not constitute a coparcenary.

Powers of Alienation

Since the interest of a Mitakshara coparcener is an undivided, fluctuating interest, a Mitakshara coparcener generally cannot alienate his undivided share by way of sale, mortgage, or gift without the consent of the other coparceners — subject to the exception in Bombay, Madras, and Madhya Pradesh which permit such voluntary alienation.

Under Dayabhaga, since every coparcener is the owner of a fixed, defined share, a Dayabhaga coparcener has absolute power of alienation over his share. He may sell it, mortgage it, gift it, or dispose of it by will, in exactly the same manner as he deals with his separate property. A purchaser at a court sale of a Dayabhaga coparcener's share is accordingly entitled to be put into physical possession of that share immediately, which is not the position under Mitakshara.

Meaning of Partition

The word "partition" carries a different meaning under the two schools. Under Mitakshara, since ownership is joint, partition consists in the severance of joint ownership — a declaration of intention to separate that immediately crystallizes the fluctuating interest into a fixed share, even if the property is not yet physically divided. The two stages — severance of status and actual division by metes and bounds — are separate events, and the first suffices to end the coparcenary.

Under Dayabhaga, since the coparceners already hold defined shares, there is no such thing as a severance of status. Partition means only the actual physical division of the property by metes and bounds — splitting up joint possession and assigning specific portions to each coparcener. A mere declaration of intention to separate does not constitute partition under this school.

The Karta and Accountability

Both schools recognize the institution of the Karta, and his powers of alienation for legal necessity and benefit of estate are substantially similar under both. However, there is one notable distinction in accountability. Under the Dayabhaga school, the Karta is required to render full accounts at any time a coparcener demands them, since every coparcener is already the owner of a defined share. Under Mitakshara, the Karta is not so obliged; he need render accounts only in three specific situations — charges of fraud, conduct of a business requiring accounts, and when a coparcener demands a partition.

The two systems, in sum, represent contrasting visions of the family and property. Mitakshara embeds the individual into the corporate body of the coparcenary from the moment of birth, making his interest derivative of and subordinate to the collective ownership — an inheritance of both land and spiritual obligation. Dayabhaga, by contrast, treats property as something that passes only when an owner dies, giving every heir a distinct and individual stake from the moment of succession. As Mulla aptly summarizes, a member of a Dayabhaga joint family holds his share in quasi-severalty, while a Mitakshara coparcener holds only an undivided interest in the whole.
