If you are under 18 years of age, you must have your biological or adoptive parent or court-appointed legal guardian sign your application to obtain a driving privilege, such as the Driver License/ID Card Application (Form 735-173). If your parents are divorced, either parent or a legal guardian may sign your application, regardless of who has custody. If a legal guardian signs, DMV must see the court document granting them guardianship.
If you are under 18 and married, you are not required to obtain a parent or legal guardian's signature. Instead, you must present documentation showing that you are married.
If you are emancipated, you must present a copy of the judgment or decree of emancipation issued by the juvenile court. A parent or legal guardian's signature is not required.
