My fiancé and I are both British, but (as is clear) not yet married. We had our first child here in November. Ideally, we would like to register his birth with the British Consulate before leaving in June to live in the UK again. We are aware that this is not necessary and we could either wait until we are back or apply for a British passport directly. (He already has his Brazilian passport). However, we'd like to do it. We understand that, in order to have my fiancé named as the father on the consular birth cert, we need to make a paternity declaration at 'the nearest consulate'. After researching this (including trying to call them and speaking to someone) I am still unclear about whether this can be done in SP (at a 'Swearing an oath or affidavit' appointment) before sending all our documents off to Rio. Does anyone have any experience of this? Thank you
