Section 50 Evidence Act: Opinion on Relationship and BSA Section 44

When a court must decide whether two people are related, the conduct of family members and others with special knowledge can be relevant evidence. The current rule is Section 44 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA), corresponding to Section 50 of the Indian Evidence Act, 1872.

Current legal position: The BSA came into force on 1 July 2024. Section 44 preserves the essential rule on opinions expressed by conduct, but updates the statutory references in the marriage-related proviso. The repeal-and-savings provision in BSA Section 170 must be considered for proceedings pending at commencement.

Section 44 BSA 2023: Opinion on relationship, when relevant

Under Section 44, when a court has to form an opinion about the relationship between two persons, an opinion expressed by conduct is a relevant fact if it comes from a family member or another person having special means of knowledge about that relationship.

Marriage-related statutory limitation

The proviso specifies that this kind of opinion, standing alone, is not sufficient to prove a marriage in proceedings under the Divorce Act, 1869, or in prosecutions under Sections 82 and 84 of the Bharatiya Nyaya Sanhita, 2023.

Thus, the law distinguishes between evidence being relevant and that evidence being sufficient to establish a legally contested marriage.

Section 50 of the Indian Evidence Act, 1872

Former Section 50 stated that, when the court had to decide the relationship of one person to another, the opinion expressed by conduct of a person with special means of knowledge, whether a family member or otherwise, was a relevant fact.

Its proviso did not allow such opinion alone to prove a marriage in proceedings under the Indian Divorce Act, 1869, or prosecutions under Sections 494, 495, 497 or 498 of the Indian Penal Code, 1860. Those references reflect the historical text; the current BSA proviso refers instead to the Divorce Act and BNS Sections 82 and 84. The former IPC Section 497 was also struck down as unconstitutional in 2018.

What makes an opinion about a relationship relevant?

  1. A relationship is in issue: for example, marriage, parentage or another familial connection.
  2. The witness has special knowledge: such as close family association, repeated dealings or long-standing observation of family life.
  3. The opinion is shown through conduct: for example, consistent treatment of two persons as spouses or of a child as a family member.
  4. The court evaluates its weight: the conduct is relevant, but its reliability and sufficiency depend on the evidence and the issue to be proved.

Statutory illustrations explained

Illustration (a): Husband and wife

The question is whether A and B were married. The fact that their friends ordinarily received and treated them as husband and wife is relevant. Such social treatment is evidence of a perceived marital relationship, but does not by itself override the special statutory proviso where proof of marriage is required.

Illustration (b): Parent and child

The question is whether A was the legitimate son of B. The fact that family members consistently treated A as B's legitimate son is relevant. The court may assess the duration, consistency and circumstances of that conduct along with other admissible evidence.

Practical examples of conduct-based relationship evidence

  • Relatives consistently introduce a couple as spouses at family events and in dealings with neighbours.
  • A family has for years treated a child as the son or daughter of a particular person.
  • People who have regularly participated in family occasions can explain the conduct they personally observed.
  • Family correspondence, civil records and other admissible materials may corroborate or contradict conduct-based testimony, subject to the applicable rules of proof.

Merely repeating family rumours or asserting an unsupported conclusion is different from describing conduct that demonstrates special knowledge. The court considers the source, opportunity to observe and credibility of the witness.

Relevance is not conclusive proof

QuestionLegal significance
Can family conduct be considered?Yes, when it meets Section 44 BSA's requirements.
Must the witness be related by blood?No. A non-family witness may qualify if they have special means of knowledge.
Does social recognition alone always establish a valid marriage?No. The proviso expressly limits its sufficiency in specified proceedings.
Can the court consider other evidence?Yes. Documentary and oral evidence is assessed under the applicable rules.

Frequently asked questions

Which provision replaces Section 50 of the Evidence Act?

Section 44 of the Bharatiya Sakshya Adhiniyam, 2023, is the corresponding provision under the new evidence law.

Is the opinion of a family member admissible?

It can be relevant if the person has special means of knowledge and the opinion about the relationship is expressed by conduct. The court determines its evidentiary weight.

Can treating two people as husband and wife conclusively prove marriage?

No. Such conduct can be relevant, but Section 44 expressly states that it is insufficient on its own in the specified divorce proceedings and BNS prosecutions.
