You cannot take your passport with you immediately after submitting your application, as it is produced at the Federal Printing Office in Berlin. If the passport is needed earlier, an express passport can be applied for.
If a trip abroad is planned immediately after the marriage or the establishment of a civil partnership, a new passport can be applied for before the marriage or the establishment of the civil partnership; in any case, it will only be issued after the marriage or the establishment of the civil partnership and once the documents supporting the name have been submitted.
When applying for the documents, suitable documents from the registry office for the marriage are required.
