The Illinois Order for Name Change (adult) is a legal document used to legally change the name of an adult living in the state of Illinois. This process is commonly used by individuals to change their name after marriage, divorce, or for any other reason. The Order for Name Change (adult) must be filed in the circuit court of the county where the petitioner (person requesting the name change) resides. The petitioner must also submit the Order for Name Change to the Illinois Department of Public Health's Vital Records Office. There are two types of Illinois Order for Name Change (adult): Standard and Joint. The Standard Order for Name Change is used when the petitioner is changing their name on their own. The Joint Order for Name Change is used when two or more adults are changing their names at the same time, such as a married couple. The petitioner must provide proof of identity and proof of residence to the court, and a filing fee must be paid. Once the Order for Name Change is filed, the court will issue an Order for Name Change, and it must be published in the newspaper. After the Order has been published, a hearing is held and the court will issue a final Order for Name Change. Once the Order has been issued, the petitioner must take the final Order for Name Change to the Vital Records Office to update their records.
