That info is on another thread and it is different depending on what your circumstances are (are you divorced? is she divorced? kids from either etc).

The cost of getting married in Germany...QUOTE (kato @ Nov 21 2007, 10:16 pm)

"Die Anmeldung kann fruestens 6 Monate vor der erplanten Eheschliessung erfolgen."
It means that from the date of the OK from the high court, you have 6 months to get married or you will have to apply again (thereby wasting around 100€ to do so).
In the end, it cost us around 100€ to apply for the marriage "license" and then the high court charged us 240€ (which is based on how much money you make - it can cost between 10€ and 310€.
The Standesamt told us that the approval from the high courst can take from 3 - 6 weeks. Our came back in 10 days. I am American and my boyfriend is German. I don't know why it was so quickly approved.
