Monogamy Requirement under Hindu Marriage Law (Section 5(i), Hindu Marriage Act, 1955)

The principle of monogamy is a foundational requirement under Hindu marriage law after the enactment of the Hindu Marriage Act, 1955 (HMA). It is mainly governed by Section 5(i) of the Act.

1. Legal Meaning of Monogamy under HMA

Section 5(i) provides that a Hindu marriage is valid only if:

“Neither party has a spouse living at the time of marriage.”

This means:

• A person cannot have more than one legally valid spouse at the same time.
• Bigamy and polygamy are prohibited.
• A second marriage during the subsistence of the first is void ab initio.

2. Legal Consequences of Violation

If Section 5(i) is violated:

• The second marriage is void under Section 11 of HMA
• It is also a criminal offence under Section 17 HMA read with Sections 494 & 495 IPC
• The second spouse generally has no legal status as “wife/husband”

3. Important Case Laws on Monogamy (HMA)

1. Lily Thomas v. Union of India (2000)

• The Supreme Court held that conversion to another religion does not dissolve a Hindu marriage.
• A Hindu husband cannot remarry after conversion unless the first marriage is legally dissolved.
• Second marriage during subsistence of first is bigamy under Section 494 IPC.
• Strongly reinforced strict monogamy under HMA.

2. Sarla Mudgal v. Union of India (1995)

• Landmark judgment on misuse of religion to bypass monogamy.
• Hindu husband converted to Islam and took a second wife.
• Court held:
  • Conversion does not automatically dissolve first marriage
  • Second marriage is invalid and punishable under IPC
• Reinforced that HMA enforces strict monogamy regardless of religious conversion

3. Yamunabai Anantrao Adhav v. Anantrao Shivram Adhav (1988)

• Held that a woman in a bigamous marriage is not a legally wedded wife
• Such marriage is void from the beginning
• She cannot claim legal status as a wife under HMA

4. M.M. Malhotra v. Union of India (2005)

• Supreme Court reaffirmed that:
  • Bigamous marriages under HMA are void ab initio
  • Such acts attract criminal liability under Section 494 IPC
• Strengthened enforcement of monogamy rule.

5. Bhogadi Kannababu v. Vaggina Pydamma (2006)

• Court held:
  • Second marriage during subsistence of first is invalid
  • Second spouse has no inheritance rights
• Clarified civil consequences of violating monogamy.

6. Smt. Priyanka v. Suresh Kumar (AIR 1971 SC 1153 – principle on bigamy proof)

• Court held that for bigamy:
  • First marriage must be validly solemnized
  • Second marriage must also be performed with proper ceremonies
• Emphasized evidentiary requirements in monogamy-related prosecutions.

7. Shankarappa v. Basamma (1963)

• Early post-HMA interpretation:
• Court held that Section 5(i) introduced statutory monogamy in Hindu law
• Any marriage violating it is void under Section 11

8. Varadrajan v. State of Madras (1965)

• Discussed requirements for proving bigamy.
• Held that:
  • Mere cohabitation is not enough
  • Valid ceremonial marriage is necessary for prosecution
• Clarified limits of criminal liability under monogamy rule

4. Key Principles Emerging from Case Law

From these judgments, the following principles are clear:

(i) Strict Monogamy Rule

• Hindu law after 1955 allows only one living spouse at a time

(ii) Second Marriage is Void

• Any marriage violating Section 5(i) is null and void

(iii) Conversion Does Not Help

• Changing religion does not bypass monogamy (Sarla Mudgal, Lily Thomas)

(iv) Criminal Liability Exists

• Bigamy is punishable under:
  • Section 17 HMA
  • Sections 494–495 IPC

(v) No Legal Status to Second Spouse

• Second wife/husband has no marital rights or inheritance rights

5. Conclusion

The monogamy requirement under Section 5(i) of the Hindu Marriage Act, 1955 establishes strict single-spouse marriage as the legal norm. Courts have consistently upheld this rule and strictly penalized attempts to violate it, especially through bigamy or religious conversion.
