I would like to know if I can change my son's family name in his baptismal certificate? He was basptized last Sept. 2004 and i made him used my family name instead of his father. I am not married to his dad but in his birth certificate, he is acknowledge to use his father's last name. Since then when my son started studying, I have let my son used his dad's last name. Now I am planning to transfer my son in a Catholic school but baptismal would conflict on his school records. What would be the process if there's any possibility to change my son's last name on his baptismal record.
