My mother and father have been legally separated for more than a years
now and my dad lives with his then "other woman". since my parents
parted ways, that woman has been using my dad's surname in ALL her
IMPORTANT documents. She would never admit that they ever got married (WE GOT THEIR MARRIAGE CONTRACT FROM NSO), as far as we all know, they can never marry because legal separation only physically separates husband and wife but the marriage bonds can never be severed. Can my mom file the case if my father and his mistress married in virac catanduanes while their residence here in manila? February 1990 po cla kinasal sa virac, pero 1987 pa po cla d2 residence sa manila. What's the jurisdiction?

Meron pong contact ang mother and father ko kahit na separate sila. Actually my sister and I ay pumupunta sa house ng mistress nila. But, we didn't know that their married na pala already. Since 1990 pa... Nag separate sila since 1987 according to my mother. But, my father cheated to my mom matagal na! Because while my christening, my father went to the hospital cause his mistress giving birth...that's december 23, 1984. My Birthday is August 10, 1984.
Thanks. Pls. Help me.
