The Act mandates monogamy, meaning a marriage is valid only if neither party has a living spouse at the time of the marriage. This was a revolutionary change, as polygamy was a common practice before 1955. Attempting to marry while already married is a criminal offense under the Act, and such a marriage is void.

It lays down specific conditions for a valid Hindu marriage, including that both parties must be Hindus, of sound mind, not under the age of marriage (18 for females and 21 for males), and not within the degrees of prohibited relationship unless custom permits. This ensures that marriages are entered into willingly and with understanding.

The Act defines 'degrees of prohibited relationship' to prevent marriages between close relatives, such as brother-sister, uncle-niece, etc., unless a custom or usage governing the parties permits it. This provision is rooted in social norms and genetic considerations.

It provides for divorce on specific grounds, such as adultery, cruelty, desertion for at least two years, conversion to another religion, mental disorder, and venereal disease. The introduction of divorce as a legal right, rather than a social taboo, was a significant reform, empowering individuals, especially women, to exit unhappy or abusive marriages.

The Act also allows for judicial separation, where spouses can live separately without dissolving the marriage. This offers a cooling-off period or an alternative to divorce in cases where reconciliation might be possible or where a complete dissolution is not desired.

It deals with void and voidable marriages. A void marriage is considered a nullity from the beginning (e.g., bigamy, marriage within prohibited degrees). A voidable marriage is valid until annulled by a court (e.g., non-consummation, unsoundness of mind at the time of marriage). This distinction is crucial for determining legal rights and obligations.

Restitution of Conjugal Rights is a provision where a spouse who has withdrawn from the society of the other can seek a decree for the restoration of their right to the other's society. However, this has been a controversial provision, with some arguing it can be used coercively.

Maintenance and Alimony: While the Hindu Adoptions and Maintenance Act, 1956 deals more extensively with maintenance, the Hindu Marriage Act, 1955 also empowers courts to order maintenance pendente lite (during the proceedings) and permanent alimony for the wife or husband.

The Act applies to all persons who are Hindus, Buddhists, Jains, or Sikhs by religion, including those who have converted to or reconverted to these religions. This broad applicability ensures uniformity across a significant portion of the Indian population.

The Act has been amended over time. For instance, an amendment in 1976 made adultery a ground for divorce and also introduced divorce by mutual consent. This mutual consent divorce provision, requiring a minimum one year separation period, was a progressive step towards recognizing the autonomy of individuals in ending a marriage.

The Supreme Court, in cases like the Shayara Bano case (though primarily about instant triple talaq under Muslim Personal Law), has touched upon the broader debate of Uniform Civil Code, highlighting the need for gender justice and equality, which the Hindu Marriage Act, 1955, has sought to address for Hindus.

A common exam trap is confusing the minimum age of marriage with the age of consent. The Act specifies 18 for females and 21 for males as the minimum age for marriage, which is different from the age of consent for sexual activity under the Indian Penal Code.
