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

¹ A minor child of un­known par­ent­age who is found in Switzer­land ac­quires cit­izen­ship of the can­ton in which he or she was aban­doned, and thus ac­quires Swiss cit­izen­ship.

² The can­ton de­cides where the child holds com­mun­al cit­izen­ship.

³ Cit­izen­ship ac­quired in this way lapses if it is es­tab­lished who the par­ents of the child are, provided the child is still a minor and will not be­come state­less.
