However, the apostille has nothing to do with the language of the document, but is an authentification of the document and its signatures, replacing the extensive legalisation process.
So, yes, I think you need the apostille on your marriage certificate.
Yes as I will be making two separate booking for the flights our checked-in luggage will not go through to our connecting flight to Dublin at Madrid airport, so we would have to passthrough immigration to collect them & check them in on our flight to Dublin.
Only my wife requires a Schengen visa, both our kids have like myself British passports so won't be subject to immigration control in Madrid.
Our marriage certificate that my wife recently submitted for her Irish visa has an apostille stamp on the back of it, but is dated from March 2113 (as I think Spain like Peru only accepts documents dated within a certain timespan, Ireland has no date restrictions that why we used that one) & it also has pages of the English translation we had done for the Irish embassy to understand & accept it attached to it, so not too sure if she could use that one?
