I live in Palm Beach County, Floridia. I'm 66 years old & have used a middle name for the past 50 years on all my documents....bank accounts, charge cards, home deed, bills etc. I recently found out there is no middle name on my birth certificate. How can I make the middle name I've used all these years as my legal name? Is it very involved and expensive? How do I go about it by myself since I can't afford attorney fees because I live on a fixed income and can't afford the hourly rates that an attorney would charge. Thanks so much in advance for your time and help.
