Bloodlines and the Law: Understanding Consanguinity in Succession
Lineal vs Collateral: How Degrees of Kinship Are Counted
Equal Treatment of Maternal, Paternal, and Half-Blood Relations
By Vishwas Kumar
New Delhi: April 16, 2026:
The law of succession has always been deeply intertwined with the concept of family, kinship, and bloodlines. The provisions outlined in the sections deal with consanguinity—the legal recognition of relationships by blood—and how these relationships determine inheritance rights. These rules are part of a framework that ensures clarity in succession, particularly in cases of intestacy (when a person dies without leaving a will).
In matters concerning consumer rights and service deficiency, the judiciary has consistently emphasized accountability and timely performance of obligations. A significant illustration of this principle can be seen in the landmark ruling of Crystal Developers vs. Smt. Asha Lata Ghosh (Dead) Through LRs , where the Court examined issues related to delay, deficiency in service, and consumer protection rights. This judgment serves as an essential precedent for understanding how courts interpret contractual obligations and protect consumer interests in real estate and service-related disputes.
Historical Scope and Application
Section 23 establishes the scope of application. It clarifies that these provisions do not apply to wills or intestacies occurring before January 1, 1866, nor to succession involving Hindus, Muslims, Buddhists, Sikhs, Jains, or Parsis. This exclusion reflects the pluralistic legal system in India, where personal laws govern succession for different religious communities. The provisions apply primarily to those not covered by personal laws, ensuring uniformity for others.
Defining Consanguinity
Section 24 defines kindred or consanguinity as the relationship between persons descended from the same ancestor. This broad definition sets the stage for distinguishing between two types of consanguinity: lineal and collateral.
Lineal Consanguinity
Section 25 explains lineal consanguinity as direct descent—either ascending (child to parent, grandparent, great-grandparent) or descending (parent to child, grandchild, great-grandchild). Each generation constitutes a degree. For example:
- A father and son are related in the first degree.
- A grandfather and grandson are related in the second degree.
- A great-grandfather and great-grandson are related in the third degree.
This precise computation ensures that inheritance rights are distributed according to closeness of bloodline.
Collateral Consanguinity
Section 26 introduces collateral consanguinity, which refers to relations who share a common ancestor but are not directly descended from one another. Examples include siblings, cousins, uncles, and nephews. The law requires counting degrees by moving upward to the common ancestor and then downward to the relative. This method ensures fairness and consistency in determining who qualifies as next of kin.
Equal Treatment of Relations
Section 27 is particularly progressive. It eliminates distinctions between:
- Relations through the father or mother.
- Full-blood and half-blood relations.
- Children born before or after the death of the deceased, provided they are born alive.
This provision reflects a principle of equality, ensuring that inheritance rights are not diminished by gendered lineage, half-blood status, or timing of birth.
Computing Degrees of Kindred
Section 28 outlines the mode of computation, supported by a table of kindred. Illustrations clarify how degrees are counted:
- A person and his first cousin are related in the fourth degree.
- A great-nephew and a first cousin are equally in the fourth degree.
- A grandson of a cousin-german and a grandson of a great-uncle are both in the sixth degree.
These examples highlight the precision required in succession law, preventing disputes over who stands closer in kinship.
Analytical Significance
The legal framework of consanguinity serves several purposes:
- Clarity in Succession: By defining degrees of kinship, the law minimizes ambiguity in inheritance disputes.
- Equality: Section 27 ensures that maternal and paternal lines, half-blood relations, and posthumous children are treated equally.
- Historical Context: The exclusion of certain communities reflects India’s plural legal system, balancing uniform civil law with personal religious laws.
- Practical Application: The computation of degrees provides a systematic method for courts to resolve succession cases.
In essence, these provisions codify the principle that inheritance should follow bloodlines in a structured, equitable manner, ensuring that property passes to those most closely related to the deceased.

OF CONSANGUINITY
23. Application of Part. — Nothing in this Part shall apply to any will made or intestacy occurring before the first day of January, 1866, or to intestate or testamentary succession to the property of any Hindu, Muhammadan, Buddhist, Sikh, Jaina or Parsi.
24. Kindred or consanguinity. — Kindred or consanguinity is the connection or relation of persons descended from the same stock or common ancestor.
25. Lineal consanguinity. —
(1) Lineal consanguinity is that which subsists between two persons, one of whom is descended in a direct line from the other, as between a man and his father, grandfather and great-grandfather and so upwards in the direct ascending line; or between a man and his son, grandson, great-grandson and so downwards in the direct descending line.
(2) Every generation constitutes a degree, either ascending or descending.
(3) A person’s father is related to him in the first degree and so likewise is his son; his grandfather and grandson in the second degree; his great-grandfather and great-grandson in the third degree and so on.
26. Collateral consanguinity. —
(1) Collateral consanguinity is that which subsists between two persons who are decsended from the same stock or ancestor, but neither of whom is descended in a direct line from the other.
(2) For the purpose of ascertaining in what degree of kindred any collateral relative stands to a person deceased, it is necessary to reckon upwards from the person deceased to the common stock and then downwards to the collateral relative, a degree being allowed for each person, both ascending and descending.
27. Persons held for purpose of succession to be similarly related to deceased. — For the purpose of succession, there is no distinction—
(a) between those who are related to a person deceased through his father and those who are related to him through his mother; or
(b) between those who are related to a person deceased by the full blood and those who are related to him by the half blood; or
(c) between those who were actually born in the lifetime of a person deceased and those who at the date of his death were only conceived in the womb, but who have been subsequently born alive.
28. Mode of computing of degrees of kindred. - Degrees of kindred are computed in the manner set forth in the table of kindred set out in Schedule I.
Illustrations
(i) The person whose relatives are to be reckoned and his cousin-german, or first cousin, are, as shown in the table, related in the fourth degree; there being one degree of ascent to the father and another to the common ancestor, the grandfather; and from him one of descent to the uncle and another to the cousin-german, making in all four degrees.
(ii) A grandson of the brother and a son of the uncle, i.e., a great-nephew and a cousin-german, are in equal degree, being each four degrees removed.
(iii) A grandson of a cousin-german is in the same degree as the grandson of a great-uncle, for they are both in the sixth degree of kindred.
FAQ: Consanguinity and Succession
Q1. What is consanguinity in law?
Consanguinity refers to the relationship between persons descended from the same ancestor. It determines who qualifies as kin for inheritance purposes.
Q2. What is the difference between lineal and collateral consanguinity?
- Lineal consanguinity: Direct descent (parent-child, grandparent-grandchild).
- Collateral consanguinity: Relations from the same ancestor but not directly descended (siblings, cousins, uncles).
Q3. How are degrees of kinship calculated?
Each generation counts as one degree. For collateral relatives, count upward to the common ancestor and then downward to the relative.
Q4. Does it matter if a relation is through the mother or father?
No. The law treats maternal and paternal relations equally.
Q5. Are half-blood relatives treated differently?
No. Half-blood relatives have the same rights as full-blood relatives in succession.
Q6. What about children conceived but not yet born at the time of death?
If born alive after the death of the deceased, they are treated as equally related for succession purposes.
Q7. Why are certain communities excluded from these provisions?
Hindus, Muslims, Buddhists, Sikhs, Jains, and Parsis follow their own personal succession laws. These provisions apply to others not governed by personal laws.
Q8. What is the significance of the table of kindred?
It provides a standardized method to compute degrees of kinship, ensuring consistency in inheritance disputes.
FINAL NOTE:
This framework of consanguinity is a cornerstone of succession law, balancing clarity, equality, and tradition. It ensures that inheritance follows a rational path through bloodlines, minimizing disputes and reinforcing fairness in property distribution.
