The main reason behind passing the Special Marriage Act, 1954 was to provide a special form of marriage for the people of India and all Indian nationals in foreign countries, irrespective of the religion or faith followed by either party. The Act originated from a piece of legislation proposed during the late 19th century.

In 1872 Act III, 1872 was enacted but later it was found inadequate for certain desired reforms, and Parliament enacted a new legislation. Henry Sumner Maine first introduced Act III of 1872, which would permit any dissenters to marry whomever they chose under a new civil marriage law. In the final wording, the law sought to legitimate marriages for those willing to renounce their profession of faith altogether ("I do not profess the Hindu, Christian, Jewish, etc. religion"). Overall, the response from local governments and administrators was that they were unanimously opposed to Maine’s Bill and believed the legislation encouraged marriages based on lust, which would inevitably lead to immorality.

The Special Marriage Act, 1954 replaced the old Act III, 1872. The new enactment has 3 major objectives:

1. To provide a special form of marriage in certain cases,
2. to provide for registration of certain marriages and,
3. to provide for divorce.

Discrepancies between Hindu law and the Special Marriage Act, 1954

Over a period of time, the Judiciary has noticed certain discrepancies caused by the parallel regimes of Hindu law and the Special Marriage Act, 1954. Most recently, in February 2008, the High Court issued notices to the State Governments of Punjab and Haryana seeking to destroy a few conflicting provisions in the Hindu Marriage Act (1955) and the Special Marriage Act, 1954. One of the conflicting provisions highlighted by the High Court was that under the Special Marriage Act, 1954, a marriage solemnized was void if either of the parties to the marriage had not attained the requisite age, but such a marriage solemnized under the Hindu Marriage Act would not be void (though punishable under the Child Marriage Restraint Act). Likewise, after attaining puberty, if a marriage is contract under the Muslim Law then such marriage is also valid and liable to be registered. If any dispute arises regarding the validity of marriage then the registration is the strongest source to prove that the marriage is valid .
