After the petition is filed you must appear before the Judge who will ask you to testify under oath that you are not changing your name for an illegal or fraudulent purpose. If you are a minor under 18 years of age, or if you are requesting a name change for a minor child under 18, a birth certificate is required, as well as the approval of both biological parents. If both parents are not appearing at the hearing, an affidavit or sworn statement under penalty of perjury granting permission for the name change provided by the parent not present; that parents joinder in a sworn/verified petition can be used in place of the affidavit or sworn statement.
Name change hearings are held on the 1st and 3rd Mondays at 9:30 am if an interpreter is not needed. Names Changes requiring an interpreter are held on every first and third Tuesday of the month at 2:30 pm.
In order to be scheduled you must for the following:
Name change petitions must be filed in Superior Court when the person desiring a change of his or her name or that of his or her child or ward is a victim of domestic violence and the person seeks to have the name change file sealed due to reasonable fear for his or her safety or that of his or her child or ward. Upon granting the name change, the Superior Court will seal the file if the Court finds that the safety of the person seeking the name change or his or her child or ward warrants sealing the file. In all such cases, whether or not the name change petition is granted, there shall be no public access to any court record of the name change filing, proceeding, or order, unless the name change is granted but the file is not sealed.
