We are a German-Vietnamese couple with a daughter, but we aren't legally married. Now we would like to declare fatherhood so that our daughter can get a German passport. A government office told us that this can only be done if we are married. Still, I have trouble accepting this answer as definite. How can it be that all kids of unmarried couples will be denied a father? Or is this possibly a rule applying only to foreigners?
Does anyone have information about this?
