If you are involved in a pending divorce case and have just learned that your estranged wife is pregnant by another man, this discovery is genuinely significant and can meaningfully affect your ongoing proceedings, and understanding exactly how to properly incorporate this development is important, drawing on the same principles discussed in relation to a husband discovering his wife's pregnancy by another man shortly after filing.

If your original divorce petition was filed on a different ground, such as cruelty or desertion, this discovery of pregnancy resulting from a relationship with another man provides powerful and specific evidence supporting adultery as an additional ground under Section 13(1)(i) of the Hindu Marriage Act, 1955, and your advocate can file an application to amend your existing petition to formally incorporate this new evidence and ground.

This pregnancy, given that it could only have resulted from sexual relations with someone other than yourself, particularly given your estrangement, represents genuinely powerful and difficult-to-dispute circumstantial evidence supporting your adultery claim, considerably stronger and more concrete than many other forms of circumstantial evidence typically relied upon in these cases, such as messages or witness testimony alone.

If paternity is genuinely in question or disputed by any party, it is worth understanding that DNA testing can provide conclusive scientific evidence establishing whether the child is biologically yours, and if you have genuine reason to believe, given your estrangement and the timeline involved, that this child is not yours, it is essential to have this properly and formally established through your divorce proceedings, both to strengthen your adultery-based ground and to protect yourself from any future ambiguity regarding legal or financial obligations toward a child that is not biologically yours.

It is genuinely important to understand the specific legal presumption relevant here: under the Bharatiya Sakshya Adhiniyam, 2023 (BSA), which replaced the corresponding provision under the old Evidence Act, there exists a presumption of legitimacy for a child born during a subsisting marriage, or within a specific period thereafter, but this presumption is specifically rebuttable where non-access between the spouses, meaning the genuine absence of opportunity for sexual relations between them during the relevant period, can be properly established, which your estrangement and separation would likely support.

If this discovery occurs while your divorce is still pending and not yet finalised, it is worth ensuring the resolution of this specific paternity question, and its proper incorporation as additional evidence for your adultery ground, is addressed before the final decree is passed, since resolving this now, within your existing proceedings, is considerably more straightforward than attempting to address it separately after your divorce has already concluded.

If this discovery has caused you significant additional emotional distress beyond what was already reflected in your original grounds for divorce, this can also be relevant to strengthening any cruelty claim you may have made, and, separately, to considerations regarding maintenance and alimony given your wife's conduct, since "the conduct of the parties" is specifically relevant to these financial determinations under Section 25 of the Hindu Marriage Act.

If you have concerns about being deemed legally responsible for supporting this child once born, given that this child is not biologically yours, it is essential to have your advocate properly and formally document this paternity question within your divorce proceedings, ensuring there is a clear, judicially recognised record establishing that you bear no legal obligation toward a child conceived through your wife's relationship with another man during your estrangement.
