I'm not any kind of lawyer, but I've been dealing with these processes here on VJ and elsewhere for just over 20 years.
Further to the OP. Key to this process, is the ability to read carefully, interpret literally, and to then answer and respond accurately. Your confusion is from not interpreting literally. There are no questions or answers involving where marriages or divorces may later have been "registered". The questions and documentation are for where the things occurred. While there are substitute documents that can be used in some isolated situations, none of them come from a country where the event being documented did not occur.
