LAST NAME OF THE CHILD
To amend the last name of a child requires the application, and a state of Illinois affidavit and certificate of correction, and the fee. If the child's last name is misspelled and that child has the same last name as a parent listed on the birth record, a copy of that parent's birth record is required. In some situations, a copy of the parents' marriage record or an older sibling's birth record also can be used. The document submitted must have been created prior to the birth of the child. If the original handwritten worksheet from the hospital of birth supports the requested amendment, a copy of this document can be submitted as proof. The hospital can send this document directly to this office.
If a Voluntary Acknowledgment of Paternity form, administrative order of paternity or court order of paternity has been completed, you can, within one year, make one change to the child's name. THIS IS ONE YEAR FROM THE DATE THE VOLUNTARY ACKNOWLEDGMENT OF PATERNITY WAS SIGNED OR PUBLIC AID OR THE COURTS ESTABLISHED PATERNITY. IT IS NOT ONE YEAR FROM THE DATE THIS OFFICE COMPLETED THE CHANGES ON THE BIRTH RECORD. The application for correction, state of Illinois affidavit and certificate of correction, and fee are required. Both parents must complete the affidavit. If either parent is not willing or unavailable to complete the affidavit, then a court order of legal name change is required.
If a court order of non-paternity was previously submitted to this office, then a court order of legal name change is required to change the child's name
