(2)  Where the parties to such marriage are related        within the degrees of consanguinity prohibited by section        1304(e) (relating to restrictions on issuance of license).            (3)  Where either party to such marriage was incapable of        consenting by reason of insanity or serious mental disorder        or otherwise lacked capacity to consent or did not intend to        consent to the marriage.            (4)  Where either party to a purported common-law        marriage was under 18 years of age.        (b)  Procedures.--In all cases of marriages which are void,     the marriage may be annulled as set forth in section 3303     (relating to annulment of void and voidable marriages) or its     invalidity may be declared in any collateral proceeding.
