The citizenship of minors and persons declared insane is determined by the parents, guardians, or officials of the law enforcement or health care authorities. The identity card acquired together with the citizenship is a basic identification document, a certificate of birth, and nationality, ethnic and cultural affiliation, a source of information on biogenetic traits, as well as an indication of the possession of inalienable individual rights.
