This site has said from its first page that the answer depends on the country. This quiz proves it in ten questions: marriage, divorce, inheritance, unmarried couples, spouse visas. The statements concern precise, checkable rules, not impressions.
After each answer the correction arrives with a link to the page that establishes it. Be aware that these rules change — every page carries its verification date.

The third is treating a foreign document as automatically valid at home: registration is almost always required.
