I am looking for help .
I'm filling in the Form AN for the naturalisation application.
Section 1.5 - State your name as it appears on your passport.
Surname/family name
Other names
On my german ID it shows my surname but also right underneath my
birth name which caused already confusion.
Do I leave the birth name away and just put my family name in there ?
But my ID shows the birth name underneath

I appreciate any help . Thanks
