I wonder how they would verify that with foreigners, especially those with a history of poor record-keeping. I surmise that there must be at least a couple of countries where a marriage certificate is nothing more than a plain sheet of copy paper with something along the lines of "I hereby declare that X and Y are married" in their local legalese.

Although I can't help but snicker at the image of a bunch of poor cops desperately trying to memorize marriage certificates from around the world.
