My mother married my step father in 1945 when I was still a baby. I grew up using his name all through school and all, and when I went to join the Navy (in 1964) I signed a form to keep my accustomed same name for my enlistment. I still use the same name, and it’s never been a problem.
Until now. I lost my birth certificate a long time ago, and recently applied to get a copy. Problem is, I need to sign the form before a notary and they won’t (of course) notarize that I am who I say I am, the person who’s name appears on the certificate, without proof of legal name change. I’ll need the cert to get a passport, etc.
The Navy people said, as I vaguely remember, that the proceedure was pretty common and that it was legal.
Question is, how can I get this proof from the Navy, or whoever holds it?
BTW; he was a great dad. 
Peace,

I went through this with my wife; besides taking my name when we married she also had a name change (through a judge) when she was a minor and we had to get a certified copy of that, too.
I don’t know why you would have a problem with a notary. If your birth name is “manfred” and the name you go by is “mangeorge” then why can’t the paper you have notarized say something like:
Not a lawyer, not your lawyer, not legal advice, etc. etc. Would be helpful to know what state/county, perhaps - they all seem to have different rules, like these.
Good point, Bug.
I’ll go to our notary this morning and ask. The horses mouth, as they say.
