Family relationships are lived, not filed. A person may be a spouse, sibling, or parent in every practical sense long before any document confirms it — and often no formal record ever exists. Section 44 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA) recognises that reality by making the opinion of family members and others with special means of knowledge, expressed by their conduct, relevant on the question of relationship. It is one of the more sensitively drafted provisions in the opinion-evidence cluster of Chapter II.
44. Opinion on relationship, when relevant. When the Court has to form an opinion as to the relationship of one person to another, the opinion, expressed by conduct, as to the existence of such relationship, of any person who, as a member of the family or otherwise, has special means of knowledge on the subject, is a relevant fact:
Provided that such opinion shall not be sufficient to prove a marriage in proceedings under the Divorce Act, 1869, or in prosecution under sections 82 and 84 of the Bharatiya Nyaya Sanhita, 2023.
Illustrations.
(a) The question is, whether A and B were married. The fact that they were usually received and treated by their friends as husband and wife, is relevant.
(b) The question is, whether A was the legitimate son of B. The fact that A was always treated as such by members of the family, is relevant.
Section 44 corresponds to Section 50 of the Indian Evidence Act, 1872 (IEA). The BPRD BSA-to-IEA correspondence table records "No change" in the section's operative substance. The only textual update is in the proviso: the reference to the IPC has been replaced with the corresponding BNS sections (Sections 82 and 84 of the Bharatiya Nyaya Sanhita, 2023).
Opinion expressed by conduct
The section departs from the ordinary understanding of "opinion" in an important way. It admits opinion "expressed by conduct" — that is, not a witness's articulated conclusion but the pattern of behaviour by which they have treated the persons concerned. If members of a family have consistently treated A as B's legitimate son, that pattern is itself the "opinion" the section makes relevant. The Court is not being asked what the family thinks in a philosophical sense; it is being told how the family has actually behaved, and it may infer relationship from that behaviour.
This choice is deliberate. Direct testimony that "X is Y's son" is often unhelpful because it merely restates the conclusion. Evidence that they have been treated as such for years — spoken to as father and son, included in family functions, referred to in correspondence, or brought into the household — is more probative because it is verifiable and less easily fabricated.
Who can express the opinion
The section admits opinion from any person who, "as a member of the family or otherwise," has special means of knowledge on the subject. Family members are the obvious class, but the phrase "or otherwise" widens the field. Long-time neighbours, family servants, close family friends, and others whose position gives them consistent, unusual access to how the persons in question have been treated may all qualify. The test is not blood tie but genuine insight.
The proviso: two situations where this opinion is not enough
The proviso is a real limit, not a formality. Even where Section 44 admits opinion-by-conduct as relevant, that opinion is not sufficient by itself to prove a marriage in two specific settings: proceedings under the Divorce Act, 1869, and prosecutions under Sections 82 and 84 of the BNS, 2023. Section 82 BNS is the offence of marrying again during the lifetime of a husband or wife (bigamy), and Section 84 BNS deals with cohabitation caused by a man deceitfully inducing a belief of lawful marriage. In both settings, marriage itself is the fact that fixes criminal or matrimonial liability, and the law requires stricter proof — typically direct evidence of the marriage ceremony and its essential rites.
| Proceeding | Section 44 opinion-by-conduct? |
|---|---|
| Civil suit turning on relationship (succession, maintenance) | Relevant and can be sufficient with corroboration |
| Marriage proceedings under the Divorce Act, 1869 | Relevant, but not sufficient to prove marriage |
| Prosecution under BNS Sections 82 or 84 | Relevant, but not sufficient to prove marriage |
The illustrations at work
The two illustrations show the section's typical application. In (a), the fact that A and B were usually received and treated by their friends as husband and wife is relevant to whether they were married — the opinion of the friends, expressed by their conduct in receiving and treating the couple, is admissible on the marriage question. In (b), the fact that A was always treated as B's legitimate son by members of the family is relevant to the legitimacy question — again, opinion by conduct rather than by declaration. Both illustrations turn on collective, observable patterns of treatment rather than on any single act.
The one drafting update
The substantive test in Section 44 is unchanged from Section 50 IEA. The BSA's only edit is a modernisation of the criminal-law references: the proviso now points to Sections 82 and 84 of the BNS, 2023, replacing the corresponding IPC references (which were Sections 494 and 495 of the IPC — the offences of bigamy and of concealment of a former marriage). Since the BSA works alongside the BNS, that update was necessary; it did not change the substantive limit on the section's use in marriage prosecutions.
Key Takeaways
- Opinion by conduct is relevant: where relationship is in question, how family members and others with special means of knowledge have treated the persons concerned is a relevant fact.
- Wide class of speakers: not only family members — anyone with genuine special means of knowledge.
- Two proviso limits: such opinion is not sufficient to prove marriage in Divorce Act proceedings or BNS Section 82/84 prosecutions.
- BNS reference update: the proviso's IPC references are replaced by BNS Sections 82 and 84 — substantively the same limit.
- Illustrations: reception as husband and wife; treatment as legitimate son.
Conclusion
Section 44 gives Indian evidence law one of its most human-scaled rules. Recognising that relationships are lived rather than certified, it lets the pattern of how people have actually been treated stand as evidence of what they are to each other. The rule is bounded by a proviso that reserves stricter proof for marriage in defined criminal and matrimonial settings, and its structural anchor — Section 50 of the 1872 Act — remains intact. Only the offence references have moved from the IPC to the BNS. In every other respect, the section continues to work as it has for generations, letting families and their long-time observers speak, through their conduct, to relationships the paperwork may never have recorded. Read alongside Section 45, it also makes the underlying pattern — the specific acts of treatment on which the opinion rests — admissible as the "grounds" of the opinion, so the court hears not only that A was treated as B's son but the concrete instances in which that treatment took place.
