Questione giuridica chiave
When did the one-year paternity-challenge period begin to run?
Decisione estratta
It began in June 2008, when the wife disclosed that a third person had been with her at conception and that the child might not be the husband's.
Motivazione estratta
For the second alternative of Art. 256c(1) ZGB, knowledge of a third party's intercourse at conception is sufficient; certainty of non-paternity is not required.
