I’ve recently married and set my appointment for name change. I have a question, I was born a different name that I currently legally have now. It was a last name change so that I could have my dad’s last name. I was around 10 years old. I have no legal documentation of the name I was born under whatsoever. I am unable to ascertain from my parents if they have any of that information. All of my current documents have my current name on them. How big of an issue will this be for me when I go into my appointment? Has anyone dealt with a previous name change before marriage? Should I try and request vital records to see if they have any records of my birth name before my appointment?
