Birth During Marriage as Conclusive Proof of Legitimacy under Section 116 of the Bharatiya Sakshya Adhiniyam, 2023, and DNA Testing

Section 116 is one of only two provisions in the Adhiniyam that declare a fact to be conclusive proof, and it was drafted in 1872 to protect children from the consequences of a label the law could not otherwise prevent. It has since collided with a technology that can answer the question it forecloses. Thirty years of decisions have worked out the relationship between the legal fiction and the scientific fact, and the Supreme Court settled it in 2026.

1. The Provision

Section 116 corresponds to Section 112 of the Indian Evidence Act and is carried forward in identical terms.

Four elements make up the foundational fact, and the presumption does not arise unless each is established.

1. A valid marriage between the mother and the man in question. Where the marriage is void or is not proved, the section has no application at all.
2. Birth during the continuance of that marriage, or within two hundred and eighty days after its dissolution.
3. Where the birth is after dissolution, that the mother remained unmarried during that period.
4. The absence of the escape clause — that it cannot be shown that the parties had no access to each other at any time when the child could have been begotten.

2. What Conclusive Proof Means Here

The second direction is what distinguishes conclusive proof from every other grade of presumption. A 'shall presume' provision yields to disproof; a conclusive-proof provision forbids the disproof from being offered. The party against whom it operates is not merely likely to fail — he is not permitted to try.

The Adhiniyam uses the expression in two places only — Section 35, on judgments in probate, matrimonial, admiralty and insolvency jurisdiction, and Section 116.

3. The Meaning of Access

Everything therefore depends on what 'access' means, and the answer has been settled for ninety years.

The consequence is a heavy burden and a deliberate one. A husband who says the child is not his must prove that he and his wife had no opportunity of intercourse at any material time — because they were separated by distance, because he was in custody or abroad, because of illness or physical incapacity, or because of some other circumstance excluding the possibility.

It is not enough to prove that the parties were living apart, or that the marriage had broken down, or that the wife was in a relationship with another man. Each of those is consistent with the continued existence of an opportunity, and the section requires its absence.

Nor is it enough to establish that intercourse did not in fact occur. The Privy Council's formulation is precise: what is in issue is the opportunity, not the act, and evidence about what the parties did or did not do is beside the point if the opportunity existed.

4. Why the Section Exists

The provision is frequently described as a relic, and understanding its purpose explains why the courts have been reluctant to dilute it.

It protects the child. The section is not principally about the husband's obligations or the wife's conduct. It is about the status of a person who had no part in either, and who would otherwise carry the consequences of a finding made in litigation between others. Illegitimacy in 1872 carried consequences in succession, in social standing and in the child's whole prospects, and it carries consequences still.

It reflects a legislative choice. The section prefers social stability and the protection of the child over biological accuracy. That was a conscious choice made at a time when biological accuracy was unobtainable, and the legislature has retained it in the Adhiniyam at a time when it is obtainable — which is itself significant.

It prevents a particular kind of litigation. Without the section, paternity would be open to challenge in every proceeding in which maintenance, succession or custody arose, and a child's status would never be secure.

5. The Collision with DNA

DNA profiling can establish or exclude paternity with a degree of certainty the section was never designed to confront, and the resulting tension has produced a line of decisions running over three decades.

5.1 The early position — primacy to the presumption

The position was applied consistently for two decades. In Banarsi Dass v. Teeku Dutta, (2005) 4 SCC 449, the Court reiterated that a DNA test is not to be directed as a matter of routine and that a roving enquiry is not permissible. In Sharda v. Dharmpal, (2003) 4 SCC 493, the Court held that a matrimonial court has the power to order a medical examination without violating Article 21, but that the power is exercised only on a strong prima facie case and sufficient material, and that refusal attracts an adverse inference.

5.2 The turn — science over legal fiction

The decision drew a distinction that has governed ever since, and that reconciles what would otherwise be an irreconcilable line of authority: the question whether to order a test and the question what to do with a test already conducted are different, and they are answered differently.

5.3 The qualification

Two later decisions pulled back from the wider reading of Nandlal Badwaik.

In Aparna Ajinkya Firodia v. Ajinkya Arun Firodia, the Court cautioned against routinely ordering DNA tests, held that a report would not automatically dislodge the presumption in the absence of proof of non-access, and recognised the child's right to privacy as a consideration in its own right.

In Ivan Rathinam v. Milan Joseph, decided in 2025, the absolutist view was relaxed by calling for a balancing of interests — the harm from a possible stamp of illegitimacy on one side, and the interest of a person in knowing his biological parentage on the other.

5.4 The present position

6. The Two-Stage Position

The decisions are often presented as conflicting. They are not, once the two stages are separated, and the two-stage analysis is the practical answer to any question in this field.

The practical consequence is that Section 116 continues to operate in the great majority of cases, because in the great majority of cases no test is ordered. It is displaced only where a reliable report already exists — and the gateway to that situation is narrow, deliberately so.

7. Refusal to Undergo a Test

Where a court has ordered a test and a party refuses, the court does not compel him physically. It draws an inference.

Sharda v. Dharmpal, (2003) 4 SCC 493 held that if, despite an order, a person refuses to submit to a medical examination, the court is entitled to draw an adverse inference against him. The same approach was taken in Goutam Kundu, and it operates through Illustration (h) to Section 119, under which the court may presume that a man refusing to answer a question he is not compelled to answer would give an answer unfavourable to him.

This mechanism operates as effective compulsion in most cases while avoiding the difficulties that literal compulsion would present. It is also, in practice, how a great many such disputes are resolved without any test being conducted.

A separate line of authority deals with the husband's position where adultery is alleged. In Dipanwita Roy v. Ronobroto Roy, (2015) 1 SCC 365, the Supreme Court permitted a DNA test where the husband had alleged infidelity, holding that the wife could decline but that refusal would carry the consequence of an adverse inference on the issue she had put in contest.

8. What Section 116 Does Not Cover

Four limits are worth stating because the section is frequently invoked where it does not apply.

It requires a valid marriage. Where the marriage is void, or is not proved, the section has no application and paternity is established or disputed on ordinary evidence.

It establishes legitimacy, not paternity in every sense. The section declares the child to be the legitimate son of the husband. Questions of biological parentage arising outside that framework — in proceedings about inheritance from a third person, for instance — are not governed by it.

It operates only within the two hundred and eighty day window after dissolution, and only where the mother remained unmarried. Outside that, the ordinary rules apply.

It does not decide maintenance in every case. As Nikhat Parveen shows, where the presumption is displaced the obligation to maintain falls with it. But a child's right to maintenance may arise on other footings under other statutes, and the collapse of the presumption in one proceeding does not necessarily determine every question about the child's entitlements.

9. The Position Stated Shortly

1. Section 116 is one of only two conclusive-proof provisions in the Adhiniyam, the other being Section 35.
2. Four foundational elements — a valid marriage, birth during it or within 280 days of dissolution, the mother remaining unmarried, and the absence of proof of non-access.
3. Non-access prevents the presumption from arising; it is not a right of rebuttal, which is why evidence on the presumed fact was for so long shut out.
4. 'Access' means the opportunity for marital intercourse, not the act — Karapaya Servai — and proving that intercourse did not occur is not enough.
5. The section prefers the protection of the child over biological accuracy, and the legislature retained that choice in 2023.
6. A test will rarely be ordered — a strong prima facie case is required, the child's privacy is a consideration, and the interests must be balanced.
7. A court-directed, unchallenged DNA report on the record prevails over Section 116 — Nikhat Parveen, following Nandlal Badwaik — but this is not an endorsement of routine testing.
8. Refusal to undergo an ordered test attracts an adverse inference rather than physical compulsion.
