Stateless persons, homeless foreigners or foreign refugees with habitual residence in Germany can submit an application to a German registry office for subsequent certification of the marriage after a marriage abroad.
The marriage must have been validly concluded in the country in which you got married. German law must not stand in the way of the marriage.
You can also have your marriage subsequently certified if you both do not have German citizenship and were married in Germany before an authorised person of a government of the state to which one of you belongs.
You are entitled to apply:

• The spouses
• If both spouses are deceased, their parents and children

The registry office of your place of residence or the place where you last lived or the place of your habitual residence is responsible for the subsequent certification. If the registry office does not have jurisdiction, the registry office I in Berlin will notarise the marriage.
