Questão jurídica principal
Whether adult-child support under Art. 277(2) CC was personally unreasonable because of the broken father-son relationship.
Decisão extraída
The support obligation was not personally unreasonable; the lack of contact was not attributable solely to the son.
Fundamentação extraída
The cantonal court had broad discretion. Although the son was not blameless, the estrangement was also caused by the mother, the father, and authorities. No exclusively culpable refusal by the son to maintain family ties was established.
