CHAPTER IV: CONSEQUENCES OF MARRIAGE UNDER THIS ACT
Section 21A: Special Provision In Certain Cases
Bare Act
21A Special provision in certain cases - Where the marriage is solemnized under this Act of any person who professes the Hindu, Buddhist, Sikh or Jaina religion with a person who professes the Hindu, Buddhist, Sikh or Jaina religion, section 19 and section 21 shall not apply and so much of section 20 as creates a disability shall also not apply.
Simplified Act
Simplified Explanation of Section 21A - Special Marriage Act, 1954:
If two people who both follow Hinduism, Buddhism, Sikhism, or Jainism get married under this law, certain rules (specifically section 19 and section 21) do not apply to them. Also, any part of section 20 that might prevent them from doing something is not applicable either.
Explanation using examples
Imagine Ravi, a Hindu man, decides to marry Priya, a Sikh woman. They choose to get married under The Special Marriage Act, 1954, which allows for inter-religious marriages. According to Section 21A of this Act, because both Ravi and Priya belong to religions that are specified in the Act (Hindu and Sikh respectively), certain provisions that normally apply to marriages under this Act are not applicable to them.
For instance, Section 19 deals with the legitimacy of children from certain marriages and Section 21 deals with penalties for making false declarations in connection with the requirements for marriage under this Act. Section 20 imposes disabilities in certain cases. However, because both individuals are from the religions mentioned in Section 21A, these sections (19, 21, and part of 20) do not apply to their marriage. This means that their marriage is free from the disabilities and penalties that might otherwise affect couples not covered by Section 21A.
