Hello @Zichako,
a very complex question as far as I can see, I did some inqueries, e.g. ****://tinyurl.***/nx698op and ****://tinyurl.***/mfntoht (both sources in German language).
Ask a special lawyer for marriage law for advice.
The European Judicial Network: states the following:
"Where should I lodge my application (petition) for divorce/legal separation/marriage annulment? Which formalities must be respected and which documents should I attach to my application?
The application for the dissolution/annulment of marriage should be made at the family court of the district in which both or one of the parties reside. The application must comply with Model 1 of Procedural Regulations of the Supreme Court of 1990. Proof of postage of the notification sent to the competent bishop or proof of receipt of a registered letter relating to the notification by the competent bishop, as well as the parties' marriage certificate should be submitted along with the application as evidence."

Maybe the consular department of the cyrpus embassy in Germany can help you:
