A Hindu marriage is a solemn union governed by statutory conditions that ensure consent, capacity, and propriety of the match. The Hindu Marriage Act, 1955 establishes that no valid Hindu marriage can be solemnized unless both parties satisfy four foundational requirements simultaneously: first, neither party must have a living spouse at the time of marriage; second, both must be of sound mind capable of giving informed consent; third, both must have attained the prescribed marriageable age (18 for females, 21 for males as per current law); and fourth, they must not be within prohibited degrees of relationship—meaning they cannot be sapindas or within the circle of persons whom custom forbids from intermarrying, unless a valid custom or usage permits such a union. These elements operate as cumulative conditions, not alternatives. If even one fails, the marriage is void from its inception. Consider how they interact: a marriage between two competent adults of legal age is still void if one is already married, because the bigamy rule operates independent of all other factors. Similarly, two unmarried persons of legal age cannot marry if one lacks sound mind, regardless of their willingness or the absence of impediment on grounds of relationship. The degrees of prohibited relationship are not absolute; they yield to established custom or usage—this creates a flexibility that prevents the Act from becoming unduly rigid, yet this flexibility itself requires proof of valid custom, not mere assertion. The interplay is thus one of strict conjunction: all elements must align for validity. The consequences of breach are severe and irreversible. A marriage contracted in violation of any condition is void ab initio—meaning it is treated as if it never existed in law. This has cascading effects: property rights between the parties are not those of spouses but of strangers; children born of such a union, however, retain legitimacy in most circumstances; a surviving "spouse" has no succession rights as a widow or widower; and claims for maintenance based on a void marriage are generally not available unless the marriage was entered in good faith by at least one party, in which case limited remedies may apply. The remedies available are primarily through a declaration of nullity sought in court; the onus of proving fulfillment of conditions rests on whoever asserts the marriage is valid. Defences are rare—they amount essentially to proving that each condition was satisfied—but good faith entry into a void marriage can mitigate harshness in matters of maintenance and legitimacy of issue. Within the broader framework of Hindu personal law, these conditions represent the modern codification of ancient principles found in classical Hindu jurisprudence, adapted for contemporary society. They sit in close relation to the doctrine of consent—while consent alone does not make a marriage valid, its absence (from unsoundness of mind) prevents validity. They also relate intimately to the law of nullity and divorce; while divorce dissolves a valid marriage, a declaration of nullity addresses a void marriage that never had legal existence. The conditions distinguish Hindu law from certain personal laws where marriages may be valid despite impediments but are voidable rather than void. Understanding these conditions is essential because they anchor the entire edifice of rights and obligations that flow from marriage in Hindu personal law. CLAT examiners frequently distort this principle in specific ways to test deeper understanding. A common trap is presenting a marriage between two unmarried persons of legal age and sound mind who are not within prohibited degrees, but omitting one critical detail—for instance, one party was previously married and the divorce decree was issued only orally without formal registration—and asking whether the marriage is valid. The examinee must recognize that even informal knowledge of a previous marriage creates an impediment. Another distortion involves reversing the burden: the question may state facts suggesting invalidity and ask "what must the plaintiff prove to establish the marriage is void?" rather than "what must the defendant prove to show it is valid?" A third trap conflates the conditions for a valid marriage with grounds for divorce or judicial separation, leading students to think that disaffection or cruelty after marriage renders it void rather than merely voidable or grounds for relief. Examiners also exploit the custom exception by presenting elaborate factual scenarios where custom is asserted but never actually proved in evidence, then ask whether the marriage is valid—the answer requires recognizing that assertion of custom is insufficient without substantive proof. Finally, a scope-creep distractor may introduce elements from the law of ceremonies and rituals, asking whether the absence of specific rituals makes a marriage void, when in fact the conditions statute is agnostic to ceremonial form—only substantive conditions matter.
