My daughter was born in Germany 1982 her mother and did not marry however I am on her birth certificate. Her mother later married and my daughter was adopted by her husband taking his name, 19 years later my daughter found out by accident she was adopted. this led her to changing her name, but not back to her mothers name, but to taking my name as per her birth certificate, subsequently she also had a daughter who was born with my name. the German system being that a child would take the mothers name. I am delighted to say all is rosy in the garden, and my daughter would like to apply for dual nationality. The previous post although give an insight to things are somewhat dated, can anyone offer any help or advice ? many thanks in anticipation.
