Questão jurídica principal
Whether the late paternity challenge was admissible under Art. 256c ZGB despite expiry of the five-year period.
Decisão extraída
The delay was excused by important reasons; the challenge had to be admitted.
Fundamentação extraída
A party need not sue before having sufficient grounds for a paternity challenge. Mere earlier uncertainty without serious indications does not necessarily require immediate action; once certainty is obtained, the claim must be filed with all possible speed. The father acted promptly after receiving the DNA result.
