I have my birth certificate given by local municipal office. It is dated the same year as my birth year but by municipal record my parents name is not in full like their passports. It has their first name and last name as initial. Do I need any affidavit for this? If required where can i get the format of the affidavit? In my wife's BC. Everything is good except its dated 2012 much later to her birth year. Any affidavit required for this and where can i get the format?
