Questione giuridica chiave
Whether the cantonal decision on child-support contributions was arbitrary because it allegedly miscalculated the father's expenses and breached his minimum vital
Decisione estratta
No. After correcting the calculation error, the father still had sufficient disposable income to pay the ordered support without infringing his minimum vital.
Motivazione estratta
For modest means, the debtor's minimum vital is protected, but child support must also respect equal treatment among children. The corrected disposable income still covered the support for the two younger children and left funds for the older child.
