The marriage between persons within prohibited degrees is declared null and void by operation of law. In respect of such a null and void marriage, an option has been left to the parties to the marriage to initiate proceedings for a declaration being made under Section 24 of the Special Marriage Act, 1954. Even in the absence of the declaration by the Court, the marriage would continue to be void in the eyes of law.
Section 25 of the Special Marriage Act provides for a decree of nullity being made in respect of voidable marriage and for the purpose it has been provided that the Court shall not grant such a decree unless the proceedings are initiated within one year from the date of the marriage.
