Ok, I deal with things like this all the time. You don't say whether it's your given name or your surname that has changed or how it came to be changed but I'll give you a few scenarios.
You will need to find the church where you were baptized. They hold the register in which your baptism was recorded and they are the only ones who can change it.
1) Adoption: If you were adopted you can take your adoption papers to the church and they will change the register to record the adoption. Usually it's an entry like this: Adopted as John Doe by Frank Doe & Mary Smith with the date and the file #. Then a new Certificate of Baptism is issued in the new name. Should you require a certificate later it will always be issued with the new name and the new parents.
2) Legal name change: Take your birth certificate to the church and request that your baptismal record reflect the name change. They'll copy your birth certificate with its number etc. and issue a new certificate.
In neither case is the record altered; a notation is simply added to the original record in the same way your Confirmation & Marriage is noted if/when they are celebrated.
I am an Indian Catholic.
]My Baptism Certificate is recorded as "Arockia Antony Arul Mathan"
*]All my other legal documents has name as "Mathan MP" where MP is the initials that we follow in our country (Educational Certificates/Passport/Financial documents)
*]As my Baptism Certificate is recorded with the full name "Arockia Antony Arul Mathan*", my marriage certificate also carries the same name
Now if I have to apply for a passport for my wife there would be confusion in the name. However in India, Marriage Certificate provided by the Church is not legal for applying a passport. Nevertheless, I do not want to keep this confusion going on for ever. Please let me know how do I go about this.
