I would like to seek legal advice about my surname.
I have been using my father's last name throughout my life. However, just last year when I was retrieving some documents required for my wedding, I found out that the surname indicated in my birth certificate was totally different from my father's last name. Aside from that, the father's name stated there was also totally different. The other contents were correct. I was thinking that I was given another person's birth certificate, so I tried to return it. I contested that it wasn't mine. But according to NSO, it was probably mine because most of the contents are correct, particularly my first name, my mother's maiden name and my date of birth. They told me that it is impossible for my mother to give birth twice on the same day.
Is there any possibility that I can change my surname? If so, what are the steps to legally execute this?
Thank you very much
