The official page does not state the application office, required documents or fees, nor whether nationality acquired by marriage passes to children (a common third-party claim that this route is not transmissible to children is unverified). Confirm the submission procedure, documents, fees and child-transmission rule with the Directorate of Judicial Services before publishing them.
