Contact the clerk of the court at your local courthouse and ask for the "petition for name change" packet - the papers you need to complete and file are included along with easy to follow step-by-step instructions to complete them. As you are an adult you will not need the permission of anyone to change your name - you will simply need to follow the instructions provided and file the papers, pay the filing fee and it will go from there. The packet will provide you with a more detailed outline of the actual steps/timeline you are going to need to follow. If the clerk of the court is unable to help you can also purchase these papers at any one of the thousands of "legal form" stores that are in the yellow pages and many have paralegals on staff to complete them for you (for a fee of course) so that you will be sure it is done properly.
