My girlfriend has a son from her previous boyfriend. Her son's name is rey anthony, 1 year old, already registered (has birth certificate already). We want to remove and replace "rey" since it's her ex-boyfriend's name. We already asked our city's municipal office on what to do and searched the internet. Found out that it falls under RA 9048 and we need:
1. Certified machine copy of the certificate containing the alleged erroneous entry or entries -this is the NSO birth certificate right?
2. Not less than 2 public or private documents upon which the correction shall be based -only baptismal certificate and medical records can be acquired at this time since he's only 1 year old. The problem is that the church asks for the birth certificate (which contains the alleged erroneous entry) before baptizing anyone. So the baptismal certificate will still have "rey" as his name.
Her son is known as "Anthony" by everyone so it would not create confusion and/or change his identity at all if we remove and replace "rey" since only my girlfriend, her mother and I knows about his other name.
If you may, could you please tell me the best possible way on removing and replacing "rey" as his other name.
Thank you very much in advance!
