Prohibited Degrees of Relationship in Marriage

Introduction

The concept of prohibited degrees of relationship refers to certain close familial relationships within which marriage is legally forbidden. The primary objective of these restrictions is to prevent incestuous unions, protect family structure, preserve social morality, and reduce the risk of genetic disorders among offspring. Under Indian family law, especially the Hindu Marriage Act, 1955, marriages between persons falling within prohibited degrees are generally void unless a valid custom or usage permits such marriages.

Statutory Framework

Under the Hindu Marriage Act, 1955

Section 5(iv) provides that a valid Hindu marriage can be solemnized only if the parties are not within the degrees of prohibited relationship, unless a recognized custom permits such a marriage.

Section 3(g) defines persons within prohibited degrees of relationship. Two persons are within prohibited degrees if:

1. One is a lineal ascendant of the other.
2. One was the spouse of the other's lineal ascendant or descendant.
3. One was the spouse of the other's brother, uncle, or granduncle.
4. They are related as:
   • Brother and sister,
   • Uncle and niece,
   • Aunt and nephew,
   • Children of two brothers,
   • Children of two sisters,
   • Children of a brother and a sister. 

The law includes relationships by:

• Full blood,
• Half blood,
• Uterine blood,
• Adoption,
• Illegitimate as well as legitimate relationships. 

Meaning and Scope

The prohibition extends beyond direct blood relations and includes certain affinity relationships created through marriage. Thus, a person cannot marry:

• His or her parent or grandparent.
• Brother or sister.
• Uncle or aunt.
• Nephew or niece.
• First cousins where covered by the statutory prohibition.
• Adoptive relatives within the prohibited category. 

Rationale Behind the Prohibition

1. Prevention of Incest

The law seeks to prohibit incestuous relationships that may disrupt family order and social morality.

2. Protection of Genetic Health

Marriages between close relatives increase the likelihood of hereditary disorders being transmitted to children.

3. Preservation of Family Structure

The prohibition maintains clear family roles and relationships.

4. Social Policy

The legislature considers such restrictions necessary for maintaining social welfare and public morality.

Exception: Custom and Usage

A marriage otherwise prohibited may be valid if a custom governing both parties permits such a union. The custom must be:

• Ancient,
• Certain,
• Continuous,
• Reasonable,
• Not opposed to public policy.

The burden of proving the custom lies on the party relying upon it.

Effect of Violation

A marriage solemnized within prohibited degrees, without the protection of a valid custom, is generally void under Hindu law. Parties may also attract statutory penalties prescribed under the Act.

Important Case Laws

1. Lila Gupta v. Laxmi Narain

The Supreme Court observed that the Act prescribes certain mandatory conditions for marriage, including the prohibition against marriages within prohibited degrees unless validated by custom.

Significance

The judgment clarified the nature and importance of statutory conditions governing Hindu marriages.

2. Thakur Gokal Chand v. Parvin Kumari

Facts

The dispute concerned recognition of customary practices.

Held

The Court held that a custom must be ancient, certain, continuous, and reasonable before it can override the general law.

Significance

This case remains a leading authority regarding proof of customs permitting marriages otherwise prohibited by law.

3. Neetu Grover v. Union of India

Facts

The petitioner challenged the constitutional validity of the prohibition on Sapinda and closely related marriages under the Hindu Marriage Act.

Held

The Delhi High Court upheld the constitutional validity of the statutory prohibition.

Significance

The Court recognized the legislative objective of preventing marriages among close relatives while preserving the exception for proven customs.

4. Rajesh Kumar v. State

Facts

The court examined the validity of a marriage in light of statutory requirements under the Hindu Marriage Act.

Held

The Court reiterated that parties must not fall within prohibited degrees of relationship unless protected by a recognized custom.

Significance

The decision reaffirmed the mandatory nature of Section 5(iv).

5. Delhi High Court Sapinda Marriage Legitimacy Case

Facts

The dispute involved a child born from a marriage alleged to be within a Sapinda relationship.

Held

The Court examined whether a valid custom permitting such marriage had been established.

Significance

The judgment emphasized that customs permitting marriages within prohibited relationships must be strictly proved through convincing evidence.

6. Indra Sarma v. V.K.V. Sarma

Facts

Although primarily concerning relationships in the nature of marriage, the Court discussed statutory conditions governing valid marriages under the Hindu Marriage Act.

Held

The Court reiterated that parties to a valid marriage must not be within prohibited degrees of relationship unless permitted by custom.

Significance

The case reinforced the continuing importance of statutory marriage conditions under Hindu law.

Comparative Position under the Special Marriage Act, 1954

The Special Marriage Act also prohibits marriages between persons within specified prohibited degrees of relationship. However, where a custom governing at least one party permits such a marriage, the restriction may be relaxed in accordance with statutory provisions.

Conclusion

The doctrine of prohibited degrees of relationship is a fundamental component of Indian marriage law. It prevents marriages between closely related persons, thereby preserving family integrity, social order, and genetic health. The Hindu Marriage Act, 1955 and the Special Marriage Act, 1954 both recognize these restrictions while allowing limited exceptions based on well-established customs. Judicial decisions have consistently upheld these provisions and have required strict proof whenever a party seeks exemption through customary practices. The doctrine thus represents a balance between statutory regulation and respect for legitimate community customs.
