Gender Reassignment

An individual born in Illinois, with an existing Illinois birth certificate, may submit an Application for Gender Reassignment to the Department requesting to have the gender changed on his or her own birth certificate after undergoing an operation(s) having the effect of reflecting, enhancing, changing, reassigning or otherwise affecting gender.

Every individual must complete the Affidavit for a New Birth Certificate After Completion of Gender Reassignment in its entirety and have it notarized. The applicant must be of legal age (or the parent/co-parent or guardian if not of legal age) to complete the form.

For individuals who have had an operation(s) in the United States, the Affidavit by Physician After Completion of Gender Reassignment must be completed by the physician who performed the operation(s). This form must be completed in its entirety and notarized.

For individuals who have had an operation(s) outside of the United States, the Affidavit by Physician Verifying Completion of Gender Reassignment Operation must be completed by an examining physician duly licensed to practice medicine in the United States. This form also can be used if the physician who performed the operation is no longer practicing, is unavailable or his/her license has been revoked or expired. This form must be completed in its entirety and notarized.

For individuals seeking to have their name changed, a certified copy of the Court Order of Legal Name Change also must be submitted to the Division of Vital Records.
