State the essential conditions of marriage among Hindus under the Hindu Marriage Act of 1955.

The essential conditions for a valid Hindu marriage are laid down primarily in section 5 of the Hindu Marriage Act, 1955, which must always be read alongside section 7 dealing with ceremonies. Together, these two provisions form the complete foundational framework of a valid Hindu marriage. What follows is a systematic examination of each condition, its legal effect, and the judicial interpretation it has received.

The Governing Provision: Section 5

Section 5 of the Act declares that a marriage may be solemnised between any two Hindus if the following conditions are fulfilled. It is important to understand at the outset that not all conditions carry equal legal weight — some violations render the marriage void ab initio, some render it merely voidable, while others only attract penal consequences without affecting validity at all.

Condition I: Monogamy (Section 5, Clause i)

The first and perhaps most absolute condition is that neither party must have a spouse living at the time of the marriage. This clause introduced strict monogamy into Hindu law — a radical departure from the pre-1955 position under which a Hindu male could take any number of wives.

The expression spouse here means a lawfully married husband or wife. Before a valid marriage can be solemnised, both parties must be either single, or divorced, or widowed. If, at the time of the performance of the marriage rites and ceremonies, either party had a subsisting marriage, the subsequent marriage is not merely irregular — it is void ab initio* under section 11, and no decree of court is needed to treat it as a nullity. Even the consent of the second spouse cannot validate such a union. The violation is also punishable under section 17, and is a criminal offence under sections 494–495 of the Indian Penal Code.

Condition II: Mental Capacity (Section 5, Clause ii)

The Act requires that at the time of marriage, neither party should be mentally incapacitated. This incapacity may arise in three ways. First, a party may be incapable of giving a valid consent to marriage in consequence of unsoundness of mind. Second, a party, though technically capable of consenting, may be suffering from a mental disorder of such a nature or extent as to make them unfit for marriage and the procreation of children. Third, a party may have been subject to recurrent attacks of insanity.

The word mental disorder is not defined in the Act itself. Courts have interpreted it in light of the Marriage Laws Amendment Act of 1976, which replaced the earlier crude language of "idiot or lunatic" with this more refined formulation. The standard, as articulated by the English courts and adopted in India, is whether the person is capable of living in a married state and of carrying out the ordinary duties and obligations of marriage.

A marriage in violation of this condition is voidable — not void — under section 12(1)(b). This means the marriage subsists until annulled by a court at the instance of the aggrieved party, and cannot be treated as a nullity without recourse to legal proceedings.

Condition III: Minimum Age (Section 5, Clause iii)

The Act prescribes that the bridegroom must have completed the age of 21 years and the bride the age of 18 years at the time of the marriage. These ages were progressively raised from their original positions of 18 and 15 years respectively by the Child Marriage Restraint Amendment Act, 1978.

This condition occupies a peculiarly anomalous position in the scheme of the Act. A marriage in violation of the age requirement is neither void nor voidable under sections 11 and 12 — both of which pointedly exclude clause (iii) from their operation. The legislature's deliberate omission reflects the social reality that imposing nullity upon child marriages would render a large number of girls, predominantly from lower strata of society, destitute and without legal protection. The contravention is, however, punishable under section 18, and now the Prohibition of Child Marriage Act, 2006 makes such marriages voidable at the option of the minor party.

Condition IV: No Prohibited Relationship (Section 5, Clause iv)

No marriage shall be valid if the parties are related to each other within the degrees of prohibited relationship, unless the custom or usage governing both of them permits such a marriage. Section 3(g) of the Act defines prohibited relationship to include: lineal ascendants and descendants; persons who were the spouse of a lineal ascendant or descendant; spouses of the brother, or of the father's or grandfather's brother; and siblings, uncle-niece and aunt-nephew relationships, and the children of siblings.

A marriage in contravention of this condition is void under section 11. The exception is significant — a custom or usage must govern both parties, must have been continuously and uniformly observed, must be certain and not opposed to public policy or abhorrent to decency and morality.

Condition V: No Sapinda Relationship (Section 5, Clause v)

Equally absolute is the bar against marriage between persons who are sapindas of each other. The sapinda relationship, as defined in section 3(f), extends on the paternal side to the fifth generation inclusive in the line of ascent, and on the maternal side to the third generation inclusive, tracing upward from the person concerned, who is counted as the first generation. Persons are sapindas of each other if one is a lineal ascendant of the other within those limits, or if they have a common lineal ascendant who falls within those limits with reference to each of them.

Like the prohibition of prohibited degrees of relationship, a marriage in violation of sapinda relationship is void under section 11, unless a custom or usage governing both the parties permits such a marriage. Courts have been consistent that any such custom must not be unreasonable or opposed to public policy, as affirmed in Balusami v. Balakrishna (AIR 1957 Mad 97).

The Ceremonial Requirement: Section 7

Over and above the conditions in section 5, a Hindu marriage must also be solemnised in accordance with the customary rites and ceremonies of either party. This is the subject of section 7, and it constitutes an independent condition of validity. A marriage not duly solemnised by the performance of essential ceremonies is, under the Act, no marriage at all.

Where the rites and ceremonies of either party include the saptapadi — the taking of seven steps by the bridegroom and the bride jointly before the sacred fire — that ceremony is mandatory, and the marriage becomes complete and binding only when the seventh step is taken. Where customary ceremonies of a community do not include the saptapadi (as among several Southern communities and tribal groups), those customary forms are fully sufficient, provided they have been continuously and uniformly observed, are certain, and are recognised as obligatory by the community.

The Scheme of Legal Consequences

A clear picture of the conditions and their legal effects is as follows:

It is thus apparent that the conditions in the Act are neither uniform in their severity nor random in their design. The three conditions whose violation makes a marriage absolutely void — bigamy, prohibited degrees of relationship, and sapinda relationship — represent barriers that the law treats as non-negotiable pillars of the institution. The condition of mental capacity, being placed in a more personal and protective domain, is left to the aggrieved party to invoke. The age condition, for socio-historical reasons, occupies the unusual position of a condition whose violation the law discourages but cannot bring itself to penalise with nullity. And the ceremonial requirement under section 7, standing apart from section 5 altogether, is the foundational threshold: without it, the question of any other condition does not even arise, for there is no marriage to examine.
