1. Core Principle of Fault-Based Separation

To obtain relief, the petitioner must prove:

• A legally recognized matrimonial offence
• That the offence was committed by the respondent spouse
• That it caused breakdown of marital relations
• That the petitioner is innocent or not equally at fault

Common Fault Grounds:

• Cruelty (physical or mental)
• Adultery/extra-marital relations
• Desertion (continuous abandonment)
• Conversion to another religion
• Mental disorder/unsoundness of mind
• Venereal disease or communicable disease
• Presumption of death (in some cases)

2. Major Grounds Explained

(A) Cruelty

Cruelty includes physical violence and mental harassment.

It is one of the most widely invoked grounds today.

Key Case Laws:

1. Shobha Rani v. Madhukar Reddi (1988)

The Supreme Court held that cruelty can be mental or physical, and dowry demands causing mental trauma amount to cruelty.

2. V. Bhagat v. D. Bhagat (1994)

The Court ruled that false, scandalous allegations in pleadings and public humiliation constitute mental cruelty.

(B) Adultery

Adultery refers to voluntary sexual intercourse outside marriage.

3. Dastane v. Dastane (1975)

The Supreme Court emphasized that matrimonial offences must be proven on a preponderance of probabilities, not beyond reasonable doubt.

Note:

After the Joseph Shine judgment (2018), adultery is no longer a criminal offence in India but remains a valid civil ground for divorce.

(C) Desertion

Desertion means permanent abandonment of one spouse by another without reasonable cause.

4. Bipin Chandra Jaisinghbhai Shah v. Prabhavati (1957)

The Court held that desertion requires:

• Factum of separation
• Intention to permanently end cohabitation (animus deserendi)

(D) Irretrievable Breakdown (Judicially Recognized Concept)

Though not explicitly a statutory fault ground, courts have used it in extreme cases.

5. Naveen Kohli v. Neelu Kohli (2006)

The Supreme Court strongly recommended introducing irretrievable breakdown of marriage as a divorce ground, emphasizing that forcing couples to stay in dead marriages causes injustice.

6. Samar Ghosh v. Jaya Ghosh (2007)

The Court laid down illustrative guidelines for mental cruelty, including sustained unjustified emotional abuse.

(E) Conversion to Another Religion

A spouse converting to another religion may give the other spouse grounds for divorce under personal laws.

Courts require proof that conversion has actually occurred and affected marital obligations.

(F) Mental Disorder

Severe mental illness making cohabitation unreasonable can also be a ground.

Courts require:

• Medical evidence
• Proof of severity affecting marital life

3. Important Principles from Case Law Development

7. Lachman Utamchand Kirpalani v. Meena (1964)

The Court clarified that in desertion cases, intention is more important than physical separation.

8. K. Srinivas Rao v. D.A. Deepa (2013)

The Supreme Court held that false criminal complaints and sustained harassment amount to mental cruelty.

9. Raj Talreja v. Kavita Talreja (2017)

The Court reiterated that false allegations and misuse of legal proceedings constitute cruelty.

4. Burden of Proof in Fault-Based Separation

• Burden lies on the petitioner
• Standard: preponderance of probabilities
• Not criminal standard (beyond reasonable doubt)

5. Criticism of Fault-Based System

• Encourages blame and hostility
• Leads to false allegations
• Difficult to prove in private marital matters
• Prolongs litigation and emotional trauma

6. Modern Shift

Courts are increasingly moving toward:

• “Irretrievable breakdown” reasoning
• Mutual consent divorce preference
• Reduced emphasis on fault attribution

Conclusion

Fault-based separation is rooted in the idea that one spouse must be “guilty” of marital wrongdoing before dissolution of marriage is granted. However, modern judicial trends, especially in India, show a gradual shift toward practical, no-fault-based dissolution principles to reduce litigation stress and preserve dignity of parties.
