Hi I don't know if I am in the right place. I was wondering how I go about having my fathers name put onto my birth certicate. He was in the american airforce and went back to the us just before I was born. My mother put fathers name as unknown. My sister, born two years before me has his name on hers. Unfortunately, he has now died. How can I legally get his name on the certificate?
Do I have to get a dna test and my sister have one too... would anyone else be able to do the dna a test? What about his brother if my sister won't have it done??

I seriously doubt that you can do it after all these years. Why would you want to? What country?

I was born and live in the UK.
I would like his name on the certificate because he was my father, why wouldn't I want it on there? Just because my mother decided against it, I don't see why I can't have it changed. I am heavily into genealogy and think it should be there, I know how awkward things are when tracing records when you don't have the relevant information.

There are very few circumstances where a birth certificate can be changed. This is because a birth certificate is an historical record, which was correct when the birth was registered.

Apparently you would have to contact the official in England, Scotland, Wales, Northern Ireland, or wherever you were born, for further details.

How recent was his death ?
