I'll add that in Estonia you can also get married and divorce entirely online with a few clicks. No need to show up anywhere, no need to wait for a long time. More and more countries in EU are getting easier in that sense - Malta has many online-everything facilities, Ireland as well. The big countries such as France, Spain, Italy seem to suffer from corruption and bureaucracy, but smaller countries tend to do a lot better - Scandinavia, Baltic countries, etc. Though of course in most places you have to become a resident, or at the very least be a EU national, as only Estonia has e-residency, as far as I know.
