A calm, structured overview before any case-specific decision.

Understand the issue

Start with facts, documents and the correct legal route

The Supreme Court of India decriminalized adultery in 2018 (Joseph Shine v. Union of India), meaning it is no longer a criminal offense. However, adultery remains a very potent civil ground for seeking a contested divorce. Furthermore, proving that a spouse is 'living in adultery' acts as a complete bar to them claiming maintenance.

Your rights

A spouse has the right to file for divorce on the ground that the other party has had voluntary sexual intercourse with any person other than their spouse after the solemnization of the marriage. A husband also has the right to refuse maintenance if he can prove the wife is living in adultery.

Assessment

Situations that change the legal response

No two matters follow exactly the same route. Identify where your facts fit before acting.

01

Seeking a contested divorce based on the infidelity of the spouse.

02

Defending against a maintenance claim by establishing that the claimant is 'living in adultery'.

03

Using evidence of an adulterous relationship to argue against granting child custody to the errant spouse.

Strategic approach

Preparation before reaction

Proving adultery in a court of law is notoriously difficult because direct evidence is rarely available. The courts rely on 'preponderance of probabilities' based on circumstantial evidence. The strategy involves establishing an 'opportunity' and an 'inclination' to commit adultery.

Court journey

How the process usually develops

A clear sequence helps you prepare for each stage without losing sight of the objective.

1

Evidence Gathering

Collecting circumstantial evidence such as hotel receipts, travel records, photographs, and witness testimonies.

2

Filing the Petition

Drafting the divorce petition specifically pleading adultery, ensuring the third party (adulterer) is usually made a co-respondent.

3

Proving the Case

Presenting the chain of circumstances to the judge to establish both inclination and opportunity beyond reasonable doubt for civil standards.

4

Maintenance Defense

Using the same evidence to file an application to deny or cancel maintenance under Section 125(4) CrPC.

Preparation checklist

Documents and evidence to organise

Preserve originals, maintain a dated chronology and avoid altering electronic material.

Share sensitive material only through an appropriate confidential channel.
Hotel bills, flight tickets, or travel itineraries showing the spouse and the third party traveling or staying together.
Photographs, videos, or CCTV footage establishing a close, romantic relationship.
Call Detail Records (CDRs) showing an unusual frequency and timing of calls (subject to privacy laws).
Testimony of private investigators or independent witnesses.
