Hello @Kikia
Nice to hear from you again!
Unfortunately I'm not an expert on this topic and there are a lot of factors that play a role during divorce that also affect the duration of the procedure. Please check out this (admittedly) very broad answer that I gave to a similar question here on Wefugees:

In general you have to be patient when you have to deal with bureaucracy in Germany.
Best regards,
Thorgen
