Any legal name advice?

If you want suggestions about how to fix the spelling on your birth certificate, you'll have to tell us what state you were born in. By the way, California allows common law name changes, and if you have been spelling your name with an e on the end all your life, and you are an adult, then you have already carried out a common law name change. Ask the DMV how to doent the common law name change. I hope you are successful, DMVs around the country routinely defy the law by refusing to recognize common law name changes.
