IF I MARRIED TWICE IN THE PHILIPPINES,DOES THE TWO MARRIAGES RECORDED IN NSO?

Yes... The two marriages if recorded properly in the city or municipality will absolutely appear in NSO. If your lawful spouse is still living in your initial marriage with no annulment, then you are legally responsible of the second marriage for BIGAMY (male). Your spouse in hypothetically second marriage can be charged for ADULTERY (female) also. Marrying twice or more (POLYGAMY) is considered Criminal Case by Law.
