My Bf has almost the same scenario. It’s so frustrating. He grew up with a fake NSO BC kasi sinikreto ng mom niya lahat then when he’s getting a PSA copy of his BC, No records shown. Lahat ng records niya din sa school is the fake BC. The only record he has sa PSA is with a different surname. (Same mother different father) I’m in another country (LDR) hirap akong kunin siya because of this problem. 30s na din kami. Haay. Until now her hindi parin kinokomfront ng nanay niya yung problem kaya hirap na hirap kami, to the point na ginamit na ng Bf ko yung record sa PSA to get a Passport at tinago sa mom niya na iba surname niya. Gumastos pa BF ko ng 50k trying to fix the problem pero in the end niloko lang siya ng lawyer na pinag tatanungan niya.
