Deed Poll Records

I was wondering if I have a unilateral act to change my name, would there be a new record on the register of births of myself with my new name?

No, you must change your birth certificate.

Im not sure!

what the guy said above ^^^^^^

But I want to change my name too

No, it would not change the birth certificate. In general, you get a Deed Poll instead of changing your birth certificate.
