Federal Act
on Swiss Citizenship
(Swiss Citizenship Act, SCA)

¹ If a minor Swiss cit­izen is ad­op­ted by a for­eign na­tion­al, he or she loses Swiss cit­izen­ship on ad­op­tion if he or she ac­quires the na­tion­al­ity of the ad­opt­ive par­ent thereby or already holds that na­tion­al­ity.

² Swiss cit­izen­ship is not lost if fi­li­ation with a Swiss par­ent is es­tab­lished on ad­op­tion or such fi­li­ation re­mains fol­low­ing ad­op­tion.

³ If ad­op­tion is an­nulled, loss of Swiss cit­izen­ship is deemed not to have taken place.
