The consequence of non-registration of a marriage under section 8 of the Hindu Marriage Act, 1955, is:

Section 8 of the Hindu Marriage Act, 1955 lets State Governments make rules for registering Hindu marriages; under section 8(2) they may make registration compulsory and provide a fine for contravention. Section 8(5) says the validity of a Hindu marriage is not affected by the omission to register it, so the "Marriage is valid but calls for imposition of penalty". Non-registration does not make the marriage void or voidable.
