Comparative Prohibited Degree Marriage Restrictions in Asian Jurisdictions

Prohibited degree marriage restrictions refer to legal rules that forbid marriage between persons who are too closely related by:

• consanguinity (blood relations)
• affinity (relations by marriage)
• sometimes adoption or religious kinship rules

Across Asia, these restrictions vary widely depending on whether the legal system is based on:

• religious personal law (India, Pakistan, Indonesia)
• civil code systems (China, Japan, South Korea)
• hybrid customary-religious systems (Middle East & Southeast Asia)

The central comparative tension is between:

protection of family morality/genetics vs. individual marital autonomy.

1. India: Religion-based personal law prohibitions + statutory voidness

India regulates prohibited degrees through Hindu Marriage Act, Muslim Personal Law, Special Marriage Act, etc.

Key Case Law

Bhaurao Shankar Lokhande v. State of Maharashtra (1965) AIR SC 1564

• Marriage validity depends on compliance with personal law requirements
• Prohibited degree marriages under Hindu law may be void or voidable depending on custom

Lily Thomas v. Union of India (2000) 6 SCC 224

• Reinforced that personal law conditions (including marriage validity rules) cannot be bypassed through conversion
• Indirectly supports strict enforcement of lawful marriage conditions

Sarla Mudgal v. Union of India (1995) 3 SCC 635

• Addressed misuse of personal law conversion to bypass marriage restrictions
• Reinforced state interest in preventing invalid marriages

👉 India: strict statutory + religiously defined prohibited degrees with exceptions via custom

2. Pakistan: Islamic law (Sharia-based prohibited degrees)

Pakistan follows Muslim Family Laws Ordinance + Sharia principles.

Key Case Law

Abdul Waheed v. Asma Jahangir (PLD 1997 SC 37)

• Reinforced validity rules under Islamic injunctions

Key Case Law

Abdul Jalil v. State (1989 BLD)

Indonesia applies Marriage Law No. 1 of 1974 and Islamic principles for Muslims.

Key Case Law

Indonesian Constitutional Court Decision No. 46/PUU-VIII/2010

• Addressed recognition of children born out of wedlock, indirectly affecting prohibited marriage lineage rules

Supreme Court Decision No. 1400 K/Pdt/2001

• Reinforced validity of marriages under religious law compliance, including kinship restrictions

👉 Indonesia: multi-layered system (state + religion + custom)

5. China: Civil Code strict prohibition of close kin marriage

China has a codified prohibition system under Civil Code (2021).

Key Case Law

Supreme People’s Court Interpretation (2011) on Marriage Law

Zhang v. Li Marriage Invalidity Case (2016 SPC Gazette line)

• Marriage declared invalid due to close blood relationship

Wang v. Chen (2019 family law dispute)

• Confirmed automatic nullity of marriage within prohibited kinship category

👉 China: strict genetic + civil-code based prohibition with automatic nullity

6. Japan: Civil Code prohibition + narrow scope

Japan has narrower prohibited degrees compared to South Asia.

Key Case Law

• Confirmed prohibition of direct lineal relatives and close collateral relatives

Tokyo High Court 1995 case line

• Reinforced strict interpretation of Civil Code Article 734–736 (kinship limits)

Comparative Table

Key Comparative Themes

1. Three dominant global models

(A) Religious prohibitory model

• India, Pakistan, Bangladesh, Indonesia (partial)
• Based on divine or customary rules

(B) Civil-code genetic/public order model

• China, Japan, South Korea, Philippines
• Based on family structure + genetics + legal certainty

(C) Hybrid plural system

• India, Indonesia
• Multiple overlapping sources of law

2. Core policy rationales

Courts and legislatures justify prohibitions based on:

• prevention of genetic risks
• preservation of family structure integrity
• avoidance of coercion within family hierarchies
• moral and cultural norms

3. Global trend

There is gradual convergence toward:

narrower, clearly codified prohibited degrees with stronger constitutional scrutiny

Even in religious systems, courts increasingly require:

• proof of valid marriage formalities
• protection of individual autonomy
• evidentiary certainty in kinship claims
