How to prove a false promise of marriage in India

A "false promise of marriage" is not the same as a breakup. Under Indian law, it becomes a crime only when a person promises marriage without intending to keep that promise, and uses it to obtain consent for sex. Courts look for two things: whether the promise was false from the start and whether that promise directly caused the consent. If both are proven, the case can attract serious offences under the new criminal code (BNS).

What is the law on false promise of marriage?

1. BNS Section 69: sexual intercourse by deceitful means
   India's Bharatiya Nyaya Sanhita (BNS) creates a specific offence when someone has sexual intercourse "by deceitful means" or by making a promise to marry with no intention of fulfilling it. Punishment can extend up to 10 years' imprisonment and fine. This covers deceptive sex that does not amount to rape.
2. Consent under a "misconception of fact"
   Consent isn't valid if it is obtained by fear or a misconception of fact. The BNS retains this principle from the IPC (earlier Section 90). It is the doctrinal base courts use in promise-to-marry cases.
3. Rape provisions (when consent is vitiated)
   If the court finds the consent was vitiated by a false promise of marriage, the act may amount to rape under BNS Section 63, with punishment set out in Section 64.
4. Cheating and related offences
   Depending on facts, "cheating" under BNS Section 318 may also be invoked, since the definition covers deception causing harm to body, mind, reputation or property. Separately, BNS Section 81 punishes deceitfully inducing a belief of lawful marriage.

What is the crime of false promise?

The Supreme Court has drawn a clear line: a breach of a genuine promise is not a crime; a false promise made in bad faith from the beginning can vitiate consent. Courts require proof that (a) the promise was false when made and (b) the promise directly led to the sexual act. This test has been repeated in recent rulings and remains the controlling standard.

Courts also warn against criminalizing ordinary relationship failures. In cases like Deepak Gulati and Dhruvaram Sonar, the Court declined to treat consensual relationships as rape when the record showed no initial deceit.

How to prove a promise to marry (and that it was false)

Use a clean, chronological case file. The goal is to show intent to deceive at the start and a direct nexus between the promise and consent.

1. Capture the promise and the timeline
   • Screenshots of chats, emails, texts where marriage is promised before intimacy.
   • Call logs and messages that show repeated assurances tied to requests for sex.
   • A dated timeline linking each promise to later sexual acts.
   • These help establish the "direct nexus" courts require.
2. Show bad faith from the beginning
   • Prior subsisting marriage, concealed identity, or fake engagement rituals.
   • Immediate refusals to meet families or fix dates despite repeated promises.
   • Contradictory conduct right after sex (blocking, threats, sudden disappearance).
   • If he suppressed identity or staged a sham "marriage," Section 81 BNS may apply.
3. Corroborate with surrounding evidence
   • Witness statements from friends, relatives, or colleagues who heard the promises.
   • Photos, travel records, or bank transfers tied to wedding planning claims.
   • Medical records in case of pregnancy or procedures, if relevant.
   • Corroboration strengthens the inference that consent flowed from the deceit, not from a normal relationship.
4. Document continued deception
   • If promises continued over months while marriage was never intended, collect each instance. Courts distinguish a long, genuine relationship that later failed from a sustained pattern of deceit.
5. Choose the right legal box
   • If consent was vitiated, police may invoke BNS 63/64 (rape).
   • If the facts show deceptive sex not amounting to rape, BNS 69 fits.
   • If lies caused broader harm (reputation, financial), BNS 318 (cheating) may be added.
   • If a fake marriage belief was created, BNS 81 is relevant.

Practical steps if you plan to file

• Write a crisp narrative with dates, places, and the first promise. Attach your evidence list.
• File an FIR at the local police station or via state e-FIR where available. Mention the applicable BNS sections that fit your facts.
• Preserve digital evidence in original format and backups.
• Avoid public posts that can be used against you; share details only with counsel.
• Seek legal advice early. Promise-to-marry cases turn on intent and timing, and the Supreme Court's standard is strict.

Defences courts often accept (so you can prepare)

• The promise was genuine at the start, but the relationship later broke down.
• The complainant's consent did not flow from the promise, but from a consensual relationship.
• Records show steps toward marriage (meeting families, arranging venues) inconsistent with initial deceit.

Why careful documentation matters

The new code (BNS) retains the consent doctrine and adds Section 69 to address deceitful sexual conduct. But the Pramod Suryabhan Pawar test still governs. Prosecutors must show a false promise made in bad faith and a direct link to the consent. Your best tool is a well-organized record that proves both.
