Requesting FB page name change, which document is best?

Hello,

I'm willing to request my Facebook page name that has 8K likes.. My category is entertainer, I am changing category so that I can request change.

However, I don't know what document to submit, I mean which one is the best and what else do I need to mention?
Basically, currently page only has my first name and last is something else, I want to change it to my full name.

I'd appreciate if anyone can help me out regarding this, pm me if so..

Regards
