Adultery is no longer a criminal offence in India, but it remains a statutory ground for dissolution of a Hindu marriage. The distinction is fundamental. In Joseph Shine v. Union of India, the Supreme Court invalidated the former criminal offence of adultery under Section 497 IPC; it did not erase adultery from matrimonial law. Section 13(1)(i) of the Hindu Marriage Act, 1955 continues to permit either spouse to seek divorce where the other spouse, after solemnisation of the marriage, has had voluntary sexual intercourse with a person other than his or her spouse.
This guide explains the present law, what must actually be pleaded and proved, the role of circumstantial and electronic evidence, the effect of condonation, privacy concerns, Family Court procedure and the distinction between suspicion, emotional intimacy and legally provable adultery.
What Section 13(1)(i) of the Hindu Marriage Act says
The statutory ground is precise. The petitioner must establish that, after solemnisation of the marriage, the respondent had voluntary sexual intercourse with a person other than the spouse. The provision is gender-neutral: husband and wife stand on the same statutory footing.
The current text can be checked on India Code — Section 13, Hindu Marriage Act.
Adultery is not a criminal offence, but remains a matrimonial wrong
The constitutional decision in Joseph Shine v. Union of India struck down the penal offence of adultery. The result is that an adulterous relationship cannot, merely because it is adulterous, lead to prosecution under the former Section 497 IPC. Matrimonial consequences are different. Divorce, judicial separation and other civil consequences continue to be governed by the personal law statute and the facts proved before the matrimonial court.
Accordingly, a divorce petition should not plead adultery as though it were a criminal charge. It should plead the statutory matrimonial ingredients and the material facts supporting them.
What must be proved?
A petitioner ordinarily needs to establish four propositions: a valid subsisting marriage; conduct occurring after solemnisation; voluntary sexual intercourse of the respondent with a third person; and absence of a statutory bar that defeats relief. The Family Court decides the matrimonial issue on the civil standard applicable to such proceedings, not the criminal standard of proof beyond reasonable doubt.
Direct evidence is rare: circumstantial evidence matters
Adultery ordinarily occurs in private. Courts therefore do not insist upon impossible direct eyewitness proof in every case. A coherent chain of circumstances may be relevant. Depending upon authenticity and context, this may include hotel or travel records, prolonged unexplained cohabitation, admissions, messages showing an intimate relationship, photographs or videos, financial records, witness testimony, pregnancy or parentage evidence where legally relevant, and other conduct from which the court can legitimately draw an inference.
But opportunity alone is not automatically proof. Nor is friendship, frequent communication, a photograph, a late-night call or social-media interaction necessarily sufficient. The evidence must be evaluated cumulatively and in its factual setting.
Electronic evidence: WhatsApp, email, photographs and location data
Modern matrimonial litigation frequently depends upon digital material. Screenshots, chats, emails, photographs, cloud records, call records and device data can be important, but admissibility and authenticity cannot be treated casually. The party relying on electronic records should preserve the original source wherever possible, avoid editing or selective extraction, retain metadata and comply with the applicable law governing proof of electronic records.
Illegally obtained or privacy-invasive material can create separate evidentiary and legal issues. A matrimonial dispute does not confer an unrestricted licence to hack accounts, impersonate a spouse, install spyware or unlawfully intercept communications.
Can WhatsApp chats alone prove adultery?
Sometimes chats may contain an express admission or, read with other circumstances, materially support the case. In other cases they prove only affection, familiarity or suspicion. The court will consider authorship, authenticity, completeness, context and corroboration. A cropped screenshot without source information is substantially weaker than a properly preserved record supported by surrounding evidence.
Emotional affair versus adultery under Section 13(1)(i)
Section 13(1)(i) is framed around voluntary sexual intercourse. An emotional relationship, flirtation or inappropriate intimacy does not automatically satisfy that statutory ingredient. Depending on its nature and effect, however, conduct falling short of proved adultery may sometimes be relevant to a separately pleaded ground such as matrimonial cruelty. The grounds should not be conflated.
For the separate cruelty framework, see our guide on divorce on the ground of cruelty under Section 13(1)(ia).
Should the alleged third person be named?
Pleadings should contain material facts necessary to disclose the cause of action, but matrimonial allegations should not become a vehicle for scandalous or unnecessary publication. Whether the alleged third person must or should be joined depends upon the applicable procedural rules, relief claimed and facts of the case. Counsel should check the relevant High Court matrimonial rules and Family Court practice before filing.
The petition should state dates, places and circumstances with as much legitimate particularity as the available evidence permits. Vague pleading such as “the respondent is having an affair” is materially weaker than a pleaded factual chronology.
Condonation can defeat relief
Section 23 of the Hindu Marriage Act requires the court, before granting relief, to consider statutory bars including condonation in cases where it is relevant. Condonation is more than merely learning of an allegation; the factual question generally concerns forgiveness and restoration of the marital relationship. Subsequent conduct may also affect whether the earlier wrong remains condoned.
A petitioner who discovered the conduct, consciously resumed marital life and later relies upon the same episode must therefore address the subsequent chronology candidly.
Collusion and taking advantage of one’s own wrong
Section 23 also requires the court to examine whether the proceeding is collusive and, where applicable, whether the petitioner is taking advantage of his or her own wrong. Matrimonial decrees are not granted merely because both sides leave an allegation undefended. The court retains a statutory duty to be satisfied that a ground for relief exists.
Where is an adultery divorce petition filed?
Jurisdiction is governed by Section 19 HMA read with the Family Courts Act where a Family Court has been established. Depending on the statutory facts, jurisdiction may arise where the marriage was solemnised, where the respondent resides, where the parties last resided together, and in the additional situations expressly provided by Section 19. A wife also has the specific jurisdictional option recognised by Section 19(iiia), subject to the statutory text.
Can divorce be filed within one year of marriage?
Section 14 ordinarily bars presentation of a divorce petition before one year has elapsed from the date of marriage. The court may permit earlier presentation in the statutory exceptional circumstances. The existence of an adultery allegation does not by itself make Section 14 disappear; the petition and any application for leave must satisfy the governing provision.
Proceedings are in camera
Section 22 HMA protects the privacy of matrimonial proceedings by requiring them to be conducted in camera and restricting publication. This is especially important where allegations concern sexual conduct, intimate messages, photographs or third-party identities. Parties should avoid reproducing intimate material unnecessarily in public-facing documents.
Burden and standard of proof
The burden lies on the party asserting the matrimonial ground. The proceeding is civil in character. Courts assess whether the pleaded ground is established on the applicable civil standard through reliable evidence and legitimate inference. Seriousness of the allegation requires careful judicial scrutiny, but it does not convert the matrimonial petition into a criminal prosecution.
Evidence checklist for the petitioner
- Marriage certificate or other proof of marriage.
- Chronology identifying when suspicion arose and what was subsequently discovered.
- Original or properly preserved electronic records.
- Travel, hotel, residence or other records where lawfully available.
- Admissions in messages, pleadings, notices or testimony.
- Witnesses with first-hand knowledge rather than hearsay.
- Financial or transactional records that genuinely connect the relevant circumstances.
- Evidence addressing any allegation of condonation.
- Proof supporting territorial jurisdiction.
Defence strategy where adultery is falsely alleged
A respondent should force the petitioner to prove the statutory ingredient rather than answer insinuation with insinuation. The defence should test dates, authenticity, source and completeness of digital records, whether the alleged opportunity existed, whether the material identifies the respondent at all, whether innocent explanations fit the facts, and whether the pleading is specific enough to permit a fair answer.
False, reckless or humiliating allegations can themselves become relevant in the wider matrimonial dispute depending upon their nature, manner of publication and proof. A respondent may also seek appropriate relief under Section 23A where its statutory requirements are met.
Can adultery affect maintenance?
Maintenance questions are governed by the particular statute invoked and should not be reduced to a slogan that “adultery cancels maintenance.” Different provisions use different language and operate at different stages. Section 24 HMA concerns interim maintenance and litigation expenses; Section 25 concerns permanent alimony. Other maintenance regimes have their own statutory conditions. The court must apply the exact provision to proved facts.
For the broader maintenance framework, see maintenance under Section 144 BNSS / former Section 125 CrPC.
Can adultery affect child custody?
Child custody is not awarded as punishment for marital misconduct. The controlling consideration is the welfare of the child. An extramarital relationship may be relevant only to the extent that proved circumstances genuinely bear upon welfare, safety, stability or parenting. Moral condemnation cannot substitute for the welfare test.
Adultery and cruelty can be pleaded together
Where facts genuinely support both grounds, a petition may plead adultery under Section 13(1)(i) and cruelty under Section 13(1)(ia) as distinct grounds. This can matter where evidence establishes humiliating, deceptive or abusive conduct but falls short of proving voluntary sexual intercourse. Each ground should have its own material facts and evidentiary foundation.
What Joseph Shine actually changed
The constitutional ruling removed criminal punishment for consensual adultery and rejected the discriminatory architecture of former Section 497 IPC. It did not create a legal right to breach marital obligations without civil consequences. The Supreme Court itself recognised the distinction between criminalisation and adultery as a civil/matrimonial wrong.
Practical pleading structure
A properly prepared petition should ordinarily set out the marriage and status of parties, jurisdiction, relevant marital history, a date-wise account of the alleged conduct, particulars of the evidence relied upon, discovery of the conduct, subsequent cohabitation or separation, absence of collusion, explanation concerning condonation where necessary, connected proceedings, and precise relief. Documents should be indexed and electronic material preserved in an admissible form.
Frequently asked questions
Is adultery illegal in India in 2026?
It is not a standalone criminal offence merely because consensual adultery occurred. It remains a matrimonial ground for divorce under Section 13(1)(i) HMA and can have civil consequences.
Is one photograph enough to obtain divorce?
Not ordinarily by itself. The court evaluates what the photograph proves, its authenticity, context and the rest of the evidentiary chain.
Is a confession necessary?
No. A case may be proved through reliable circumstantial evidence, although a genuine admission can be important.
Can a spouse hack a phone to collect proof?
A matrimonial case does not authorise hacking, spyware, impersonation or other unlawful access. Evidence collection should remain within lawful bounds.
Can an emotional affair amount to adultery?
Not automatically under Section 13(1)(i), which uses the statutory ingredient of voluntary sexual intercourse. The same conduct may, on appropriate facts, be relevant to another matrimonial ground.
Can the court grant judicial separation instead of divorce?
Section 13A permits alternate relief of judicial separation in appropriate divorce proceedings, subject to the statutory exceptions and facts.
Key takeaways
Adultery remains a live and important divorce ground in India despite decriminalisation. The strongest cases are not built on surveillance, suspicion or moral accusation; they are built on precise pleading, lawful and authentic evidence, a coherent chronology and correct application of Sections 13, 14, 19, 22 and 23 HMA. The distinction between criminal law and matrimonial law after Joseph Shine should be stated accurately from the outset.
