The country clerk said I could go by what I want as far as a last name on my marriage certificate but whatever the person that marries me puts on it, that will legally need my name. Can I add a middle name since I currently don't have one? Will that be legal?
No, you cannot just add a name. A name change requires a court order.
The opinion that I express should not be considered to be legal advice that can be relied on. It is based only on the limited amount of information provided rather than doing a thorough review of all of the important information that is required to give accurate legal advice. You should consult with an attorney that has extensive background in the area of the law that your are inquiring about.
When you get married you can legally change your name, but it needs to be changing your name to the last name of your spouse, or hyphenating your names, or something very directly related to your marriage. You could keep your maiden name as a middle name if you didn't have a middle name before. But in order to pick a new or different name, you would need to file with the court for a legal name change.
