The document discusses void marriages under the Hindu Marriage Act of 1955. It defines a void marriage as one that contravenes sections 5(i), 5(iv), or 5(v) of the Act. Section 5(i) prohibits a marriage if either party already has a living spouse. Section 5(iv) prohibits a marriage within a degree of prohibited relationship, unless permitted by custom. Section 5(v) prohibits a marriage between sapindas, or close kin, unless permitted by custom. A marriage that violates any of these conditions can be declared void by court decree under section 11 of the Act.
