If a German national has married outside Germany and the marriage is valid under German law, the spouses can have the marriage registered in the German marriage register in order to obtain a German marriage certificate.
The spouses do not need to apply jointly; either spouse can apply for registration. However, if you would like during the registration to make a declaration of marrried name, both spouses must attend the appointment in person.
This information also applies to same-sex civil partnerships accordingly.
If you would like to apply for registration of your marriage in the German marriage register (with or without a declaration of married name), the necessary documents must be sent to the Embassy or Consulate General as simple copies (NO ORIGINALS!) before booking an appointment.
Depending on the case more documents may become necessary and be requested at a later stage by the registry office.
In particular, German translations of documents (including documents in English) may be required at a later stage. Occasionally apostilles are also required on foreign documents. You can find information on how to get your British documents issued with apostilles here.
Fees will be payable to the registry office in Germany for registration of a marriage registered abroad and for issue of the German marriage certificates. These fees are subject to the law of the federal state in which the registry office is located and may also vary according to the case. The fee will probably be between 80 and 120 euros.
Usually the registry office will send a request for payment of the fees before beginning to process the application. Fees payable to the registry office cannot be paid through the German Embassy or Consulate; they must be paid direct to the registry office (by bank transfer from the UK or through relatives or friends in Germany).
The processing times for registering a marriage differ from one registry office to another, but can be long. If neither of the spouses/ civil partners has ever been resident in Germany, the processing time will be at least two to three years. The Embassy and Consulate are unable to influence processing times in Germany and also cannot predict how long the procedure will take.
