Question on divorce. please help!!?

My husband and I have been married about a year and a half. We have been separated for 6 months now. I currently live in a different state than him. We own nothing jointly nor do we have children. I want to file for divorce. How do I go about doing that? Do I need a lawyer even-though we have nothing to fight over? Also, do not wish to recieve spouse support. Please help direct me in the right direction. Also, I was wondering if the "apply for divorce online" are legit?!? Please help. Thanks in advance. :-)
