Thanks for all your replies, I ended up having a very similar experience to Ben's.
Another couple questiona if you don't mind: I've already gotten my high school records+diploma, social security, and license changed. I know I still need to change my university records for next year, my insurance, and my CDIB(I'm native). I don't have any other bills really as I'm 18 and jobless. However, would anyone mind posting a list of things that do need to be changed, I'm rather afraid I'll miss something.
Also, I'm going to college in August and I won't be taking a car. In order to change my insurance, I'd have to tell my mother I changed my name since she pays everything. Considering I'll be moving so soon, I don't really want the stress of telling her right now. Is it imperative I move my insurance over?
I've applied for all college scholarships so far in my legal name as well. If I receive any aid, will I need to contact the granting agency of the name change before they try to send it to my uni account-I'm not sure if the financial aid office at my school would deal with that or not.
Thanks again.
