Marrying a Russian or Ukrainian partner in Switzerland

Russia and Ukraine apply the Hague Convention: all civil status certificates must be apostilled, then translated using the exact spelling in the passport.

Russia: documents
Duplicate birth certificate (свидетельство о рождении, marked «ПОВТОРНОЕ») from the ZAGS, proof of residence, passport
Russia: single status
According to the Swiss embassy, no certificate of single status is required
Russia: divorce
Duplicate divorce certificate and decree
Ukraine: documents
Duplicate birth certificate (свідоцтво про народження), notarised declaration of civil status, certificate of residence
Ukraine: divorce
Register extract (витяг) showing the name before the previous marriage, decree with the date it became final
Apostille
Required on all civil status certificates

Common pitfalls

Names must be transliterated exactly as in the international passport. Allow more than 12 weeks if the procedure goes through the Swiss embassy in Moscow. For people from Ukrainian territories outside government control, alternative solutions exist.
