He wanted a DNA test to prove his wife's child wasn't his. The court said no.

He claimed his wife's child wasn't his—but never actually denied paternity. So when he asked for a DNA test, the judge said: not so fast.

The man stood before the Kerala High Court with a single request: order a DNA test. He believed the child his wife was raising was not his. But he had never said those words aloud—not to her, not to the Family Court, not in any legal document. He had only hinted. The court had one question to answer: Can a man demand a DNA test just because he suspects—even when he never once said, directly, "I am not the father"?

The answer, delivered in Sujith Kumar S. v. Vunaya V.S., was a firm no. And in that refusal, the court drew a line that every family lawyer, every spouse contemplating a paternity challenge, and every judge handling maintenance disputes needs to understand.

When the husband stopped paying

The case began in a Family Court. A wife sought maintenance—financial support—for her child. The husband responded with an unusual defence. He did not deny paternity outright. Instead, he argued that his wife suffered from mental illness, and therefore, he claimed, they had "no occasion for sexual intercourse" due to that illness—the exact phrasing from his petition. The husband's affidavit, typed on yellow legal paper, contained no direct denial. It circled the question, raised a doubt, but never landed on a clear statement: "I am not the father."

He did not say: "I am not the father." He said: "Given her condition, it is unlikely." Then he asked the court to order a DNA test to settle the question.

The Family Court refused. The husband appealed to the Kerala High Court.

Why "suspicion" is not enough

The High Court examined the husband's petition closely. What it found was telling: the husband had never, at any point, specifically denied paternity. He had not alleged that his wife had been unfaithful. He had not named another man. He had simply raised a doubt—and then asked science to resolve it. The child's birth certificate lay on the judge's desk, a quiet document that the husband never directly challenged.

The court held that this was not enough. A DNA test, the bench observed, is not a "device to clear suspicion." It is a tool with a specific legal purpose: to rebut the "conclusive proof" under Section 112 of the Evidence Act—a legal rule that says a child born during a valid marriage is conclusively presumed to be the husband's child. To trigger that rebuttal, a husband must do more than hint. He must make a clear, categorical denial of paternity—and back it with some basis.

The court relied on Aparna Ajinkya Firodia and reiterated that DNA tests or any other scientific test should be allowed "only in rare and exceptional cases of deserving nature, when it becomes indispensable to resolve the controversy." The core logic was that the DNA test is intended to rebut the 'conclusive proof' under Section 112 of the Evidence Act, but it is "not a device to clear suspicion, regarding paternity."

What the Supreme Court had already said

The Kerala High Court relied heavily on two Supreme Court precedents. The first was Aparna Ajinkya Firodia, where the Supreme Court held that DNA tests should be allowed "only in rare and exceptional cases of deserving nature, when it becomes indispensable to resolve the controversy."

The second was Dipanwita Roy v. Ronobroto Roy, which set the bar even higher. In that case, the Supreme Court said that a direction to conduct a DNA test should be avoided if possible, because the legitimacy of a child should not be put to peril. But it carved out a narrow exception: if a husband makes "clear and categorical assertions" alleging infidelity, names the alleged father, and can prove that it would be "impossible" for him to substantiate his case without a DNA test—then the test may be justified.

The husband in Sujith Kumar met none of these conditions. He had not named anyone. He had not alleged infidelity. He had only raised a suspicion based on his wife's medical condition—the mental illness that he claimed made sexual intercourse impossible. The court found that the husband did not deny access to his wife at any point and did not make a consistent case denying the child's paternity.

When the test would be justified: the Dipanwita Roy standard

To understand the court's logic, consider the standard set by Dipanwita Roy. In that case, the Supreme Court considered a husband who had made specific, named allegations of infidelity against his wife. The husband in Dipanwita Roy had asserted that his wife had an affair with a named individual, and that he had no access to her during the relevant period. The Supreme Court held that in such a situation—where the husband makes "clear and categorical assertions" and names the alleged father—a DNA test may be justified because it would otherwise be "impossible" for the husband to substantiate his case.

Now compare that to the husband in Sujith Kumar. His petition said: "My wife suffers from mental illness. We had no occasion for sexual intercourse. Please order a DNA test." No name. No allegation of infidelity. No direct denial. The court saw this for what it was: a fishing expedition, not a genuine dispute.

In the courtroom, the wife's lawyer held up a single sheet—the maintenance petition—and read the husband's response aloud. The words were careful, evasive. They raised a doubt but never committed to a denial. The judge noted the absence of any specific assertion.

The Family Court's reasoning

The Family Court, which first heard the case, had already considered the facts carefully. It found that the husband did not deny access to his wife at any point during the marriage. The court also noted that the husband did not make a consistent case denying the child's paternity. Instead, his petition was a moving target—first hinting at doubt, then asking for a test, but never landing on a clear denial. The Family Court applied the same principle that the High Court would later affirm: a DNA test is not a device to clear suspicion.

The Family Court's file, now before the High Court, contained the husband's original petition. The pages were thin, the arguments sparse. There was no affidavit from any witness. No medical report beyond the husband's own assertion about his wife's mental illness. The entire case rested on a doubt—and a request to have science resolve it.

The child's interest comes first

Underlying the court's reasoning was a deeper principle: the welfare of the child. The legitimacy of a child—the legal status of being born to married parents—carries significant social and legal consequences. A DNA test, even if it confirms paternity, can still stigmatise the child and destabilise the family unit. The court made clear that a husband cannot use a DNA test as a fishing expedition. If he wants to challenge paternity, he must first state his case clearly, on the record, with specificity. Only then does the court consider whether the exceptional step of a DNA test is warranted.

The court held that in the "absence of specific denial of paternity of the child, DNA tests cannot be resorted to for clearing a suspicion regarding a child's paternity." The husband's application to conduct a DNA test was dismissed.

THE PLAY: Before filing a paternity challenge, ensure your client has made a specific, categorical denial of paternity on the record—suspicion, without more, will not move the court.

The line between doubt and denial

The Kerala High Court's judgment is a reminder that the law does not treat paternity as a question of scientific curiosity. It treats it as a question of legal status, with profound consequences for the child. A husband who suspects must first commit to a position. He cannot ask the court to test his doubt into certainty.

The husband's application was dismissed. The child's legitimacy remained intact. And the law held its ground: a DNA test is for rare and exceptional cases—not for clearing a shadow of suspicion.
