It's been about seven years so this may be outdated, I had to talk to the family court clerk and file the paperwork.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.

It's been a bit, but all I had to do was fill out the paperwork, go in front of a judge, pay the fee, and wait a bit for the required publications to run and then I got the court order saying it was official. It honestly was easier to get the name changed than it was to update everyone that needed it. I think I ended up needing like 5 official copies to send to various places.

My judge did ask why I was changing my name but did not have any issues that it was because I was trans, if that is anyone's concern. They do it to make sure you are not trying to hide from the law or bill collectors.

Here is the form for an adult name change.
