My son from my first marriage carries a birth certificate with 1 st fathers surname, we got divorced and court has granted me the custody of my son. I got married again and with adoption deed and paper advertisements we got Name changed . After inquiring with customer care of PSK, i was told that the name on the passport would be as birth certificate and fathers name would be the same in birth certificate. As there is no existence of the person whose name written on birth certificate in my sons life. I would want his passport with new credentials. Pls advice.
