Section 69 applies where sexual relations are induced by deception, such as a false promise of marriage made with no intention to marry at the reveal time. In your case, the key facts work in your favour:
• The marriage actually took place with free consent of both parties after the pre-marital intimacy.
• There was no penetrative sexual intercourse before marriage, as you have clearly stated.
• The intimacy (kissing/hickey) was mutual and consensual, not induced by fraud or misrepresentation.
• You did not abandon the marriage; instead, you went ahead and married her, which strongly negates any allegation that intimacy was obtained by a false promise.
• The marital dispute arose after marriage, due to her continued emotional involvement with another person.
Courts have consistently held (even under the earlier IPC Section 376 jurisprudence) that where marriage actually takes place, allegations of “promise to marry” based deception generally do not survive, unless it is shown that the marriage itself was a sham or fraud ab initio. From your narration, there is no such indication.
As regards your divorce petition, you have filed it on the ground of cruelty, citing emotional infidelity, lack of emotional commitment, and concealment of material facts. That is a civil matrimonial dispute, and merely alleging in the divorce pleadings that she married “without interest” does not automatically translate into criminal liability for you.
Can she still attempt to file a complaint? Practically, yes—anyone can file a complaint. But for it to sustain:
• She would have to prove intentional deception at the time of intimacy, and
• That the intimacy was solely because of a false promise of marriage, and
• That you never intended to marry her, which is contradicted by the fact that you did marry her.
The absence of Snapchat chats does not harm you. In criminal law, the burden is on the complainant, not the accused. Your strongest defence is the undisputed fact of marriage, followed by her own post-marriage conduct.
As a precautionary strategy:
• Preserve all evidence of her post-engagement and post-marriage chats indicating emotional infidelity and lack of commitment.
• Avoid confrontational communication.
• If you apprehend a false criminal case, you may consider anticipatory bail as a preventive step if any complaint is filed.
• Your divorce case itself establishes that the breakdown was due to her conduct, not yours.
In summary, Section 69 BNS is unlikely to apply to you on these facts, and no other cognizable offence is automatically attracted merely because the marriage has failed. Your legal position is defensible, and the marriage itself is your strongest shield against any “false promise” allegation.
