2. Essentials of a Valid Hindu Marriage — The Five Conditions Under Section 5

Section 5 of the Hindu Marriage Act, 1955 is the single most-tested provision in this unit, because almost every other topic in family law eventually loops back to it — void marriages, voidable marriages, bigamy, even succession disputes turn on whether a marriage actually satisfied these five conditions in the first place. The trap most students fall into is treating all five conditions as equally serious. They are not — and knowing exactly which violation voids a marriage, which merely makes it voidable, and which does neither is what separates a strong answer from a shaky one.

The Problem This Topic Solves

A marriage can go wrong in several different ways — one party might already be married, one party might lack the mental capacity to consent, one party might be underage, or the couple might be too closely related. Section 5 does not treat these failures identically, and the Act's own later sections (11, 12, and 18) attach completely different consequences to each. This post works through all five conditions and, more importantly, what actually happens when each one is broken.

The Five Conditions Under Section 5

For a Hindu marriage to be validly solemnised, Section 5 requires that, at the time of the marriage:

1. Neither party has a spouse living — the monogamy condition.
2. Neither party is incapable of giving valid consent due to unsoundness of mind, or suffers from a mental disorder making them unfit for marriage and procreation, or is subject to recurrent attacks of insanity.
3. The bridegroom has completed the age of twenty-one years and the bride the age of eighteen years.
4. The parties are not within the degrees of prohibited relationship, unless their custom or usage permits it.
5. The parties are not sapindas of each other, unless their custom or usage permits it.

Condition 1 — Monogamy (Section 5(i))

Neither the bride nor the groom may have a living spouse at the time of the marriage. This single condition converted Hindu marriage from a system that historically tolerated polygamy into a strictly monogamous one. A marriage solemnised in breach of this condition is void from the very beginning under Section 11 — it never legally existed at all, and neither party needs a court decree to treat it as non-existent, though obtaining one is still advisable for clarity on record.

Condition 2 — Mental Capacity (Section 5(ii))

Both parties must be capable of giving valid consent and fit for marriage. This condition actually covers three distinct situations: complete incapacity to consent due to unsoundness of mind, a mental disorder serious enough to make someone unfit for marriage and raising children (even if they can technically consent), and recurring attacks of insanity. Unlike the monogamy condition, a breach here does not make the marriage void — it only makes it voidable at the option of the party affected, under Section 12(1)(b).

Condition 3 — Age of the Parties (Section 5(iii))

The bridegroom must have completed twenty-one years and the bride eighteen years at the time of marriage. This is where students most often go wrong: violating the age condition does not make the marriage void, and it does not make it voidable either. The Act's only response to an under-age marriage is a criminal penalty under Section 18 for whoever solemnised or participated in arranging it — the marriage itself remains fully valid and binding on both spouses.

Conditions 4 & 5 — Prohibited Relationship and Sapinda Relationship

"Degrees of prohibited relationship" are defined in Section 3(g) — broadly, close blood relations, certain relations by half or uterine blood, and specified relations by marriage (such as a person and their spouse's sibling). "Sapinda relationship" is defined in Section 3(f) and extends, through the mother's line up to the third generation and the father's line up to the fifth generation (counting upwards from the person in each case, inclusive of the person themselves as the first generation), covering common ancestry that Hindu law treats as too close for marriage. Both conditions carry an important escape clause: if a genuine custom or usage governing either party actually permits such a marriage, the marriage remains valid despite the relationship — this is why marriages between certain close relatives are recognised as valid in some South Indian communities where such custom is proved. Where no such custom applies, a marriage in breach of either condition is void under Section 11.

Comparing the Five Conditions

• Section 5 lists five conditions: monogamy, mental capacity, age, prohibited relationship, and sapinda relationship.
• Breach of Section 5(i), (iv), or (v) makes the marriage void under Section 11.
• Breach of Section 5(ii) makes the marriage only voidable, under Section 12(1)(b).
• Breach of the age condition, Section 5(iii), does not affect the marriage's validity at all — it only triggers a penalty under Section 18.

• Prohibited relationship and sapinda relationship are both statutorily defined — in Sections 3(g) and 3(f) respectively — and both allow a valid custom to override the general prohibition.
• The full mechanics of void and voidable marriages (Sections 11 and 12) are covered in a later post in this unit.

A Practical Example

A 20-year-old groom marries an 18-year-old bride with full ceremonies performed. The marriage violates Section 5(iii), since the groom has not completed 21 years. Is the marriage void? No — it remains a fully valid marriage. The only legal consequence is that whoever solemnised the marriage, and possibly the groom's parents if they procured it, may be liable to punishment under Section 18. The couple's marital status itself is completely unaffected.

Quick Revision Points

• Five conditions under Section 5: no living spouse, mental capacity, age, prohibited relationship, sapinda relationship.
• Void on breach: Section 5(i), (iv), (v) — via Section 11.
• Voidable on breach: Section 5(ii) — via Section 12(1)(b).
• No effect on validity: Section 5(iii) age condition — only a Section 18 penalty.
• Custom can override the prohibited-relationship and sapinda-relationship bars, but not the other three conditions.
