Have you ever used any other name? Name change document


I am stuck on this question. I changed my birth name years ago and my all legal and educational docs are on my new name. I am not using my old name anywhere. So do I have to say ‘Yes’ or I can choose ‘No’.

If yes, then would LOE and an affidavit be enough? Some people have said that if old name is not on any document then I don’t have to choose ‘Yes’.
