It's been about seven years so this may be outdated, I had to talk to the family court clerk and file the paperwork. They then set the date to go in front of the judge and back then they also did the putting the name change in the publication, but I think that has since changed.

On Greene county circuit Clerk's website under the name change section, they list their number, I would call them for the most up-to-date info on the process.
