Obtain the PC-901 application form from either your local Probate Court or online using the following link: http://www.jud2.ct.gov/webforms/default.htm#PROBATE and scrolling down to the appropriate form. Minors should obtain the PC-900 form.
Fill out the form. You will need to include the name on your birth certificate, the name you want it changed to, your birthdate and place of birth, your social security number, your address, and the reason you want to change your name.
Sign the form and submit it along with a check for $49 to your local probate courthouse by mailing it or delivering it in person. A judge will review your application and grant you the name change as long as he or she deems it is not for the purpose of facilitating illegal activity.
