(PILA)

1 The Swiss au­thor­it­ies at the child’s place of birth or ha­bitu­al res­id­ence, as well as those of the dom­i­cile or the place of ori­gin of the moth­er or the fath­er, have jur­is­dic­tion to re­ceive the ac­know­ledg­ment of a child.

2 When an ac­know­ledg­ment takes place in ju­di­cial pro­ceed­ings in which the par­ent-child re­la­tion­ship is leg­ally rel­ev­ant, the judge seized with the law­suit may also re­ceive the ac­know­ledg­ment.

3 The courts that have jur­is­dic­tion to hear an ac­tion to de­clare or con­test a par­ent-child re­la­tion­ship (Art. 66 and 67) also have jur­is­dic­tion to rule on a chal­lenge of an ac­know­ledg­ment.
