The Special Marriage Act of 1954 provides a framework for marriage between two individuals in India regardless of religion. Key provisions include allowing those of sound mind over 18/21 to marry without religious restrictions, a notice and objection period overseen by a Marriage Officer, and a process for solemnizing the marriage that includes declarations and certificates. The Act also establishes grounds for void, voidable, and dissolved marriages as well as judicial separation and divorce, with succession governed by the Indian Succession Act of 1925.
