Key legal question
Whether the father's duty to support his adult son under Art. 277(2) ZGB remained reasonable despite the absence of any personal relationship.
Extracted holding
Yes. The father intentionally prevented any parent-child relationship from birth, so the son's later lack of contact could not make support unreasonable.
Extracted reasoning
Art. 277(2) ZGB turns on overall circumstances. A parent's prolonged, deliberate refusal to build a relationship with the child and disregard of the child's welfare can justify continued support after majority; the son could reasonably expect rejection and was not obliged to keep trying to establish contact.
