Here’s a site for the U.S. military on how to get married in Germany, Denmark and Switzerland. I presume it dates back to the times when more Americans were here. I remember the Danes offered a weekend marriage package, included in which I believe were translations at lower cost than in Germany. (I’m not sure where Switzerland fits in – oh, I see, U.S. NATO personnel in Basel, as they call it). The materials include the apostille text.
