Hello guys, I am here again to ask you advice/help. Our son was baptised in Catholic Church at Mabolo Cebu. The problem is we just discovered his baptismal cert.that there was an error coz they put my surname when I was in single instead of my married surname...Is it possible to get a new baptismal cert.and tell them to correct the error?

Btw,our son got a place at St.Mary Catholic School. we just worried what if time will come they will question about our son baptismal cert.
Pls. help tnx!
