Or the French make car (Renault), you purchased in a Serbian speaking nation comes with instruction manuals in Italian.
But we recently attended a wedding here, and the differences to what we've experienced in America were quite interesting. First, religious leaders do not have the legal authority to marry people. Neither Orthodox or Catholic priests, Protestant pastors or Muslim Imams can formally join two people in the bonds of matrimony. A couple wishing to wed must go to the special government office created for that purpose.
The bride and groom get one attendant/witness each, called the kuma and kum respectively (this is also the title "godmother" and "godfather"). The official reads out the Montenegrin "laws of marriage" which include that the husband and wife are equal, and they must agree on where to live but are independent in choosing where they work. They promise to abide by these rules, "take" one another as spouse, exchange rings, kiss, and sign the marriage register.
