first marriage is valid.
it should be dissolved legally by competent court by issuing divorce decree.
the deed of divorce is having no value. it does not dissolve first marriage.
second marriage is no marriage in the eyes of law as it happened without dissolving first marriage.
so the first marriage still subsists in the eyes of law.
second marriage is void. so divorce is not applicable to 2nd marriage.
u may file petition u/s 11 of HMA, 1955 to get second marriage declared void by court.
if u apply for divorce for 2 nd marriage, ur divorce petition will not be maintainable.
