And also the Standesamt replied on me with that message:
Guten Tag !
Wenn die Ehe bereits geschlossen wurde, müsste diese beim Bürgeramt registriert werden.
Dazu sollte eine Heiratsurkunde im Original mit einer Apostille und Übersetzung vorgelegt werden.
Mit freundlichem Gruß
Standesbeamter
In translation:
Good day !
If the marriage has already been concluded, it would have to be registered at the Citizen's Office.
For this purpose, a marriage certificate should be presented in the original with an apostille and translation.
With kind regards
Registrar
Therefore, I think it would be good if you write an e-mail to Kyiv and try to get the marriage certificate would that be an option? By future husband you mean that you haven't get married yet? Or that you haven't registert your marriage yet?
We are happy to continue to be there for you, feel free to keep us informed
with kind regards
Saskia
