The Special Marriage Act of 1954 allows people in India to have civil marriages regardless of religion or faith. It provides a legal framework for inter-caste and inter-religious marriages through a process of registration and notice. Under the Act, a marriage officer can solemnize marriages after a 30-day notice period if no objections are filed. The Act also covers divorce on grounds like cruelty, adultery or desertion. It promotes gender equality and non-discrimination by allowing people from different religions and castes to marry.
