Questione giuridica chiave
Whether the daughter's reform appeal was admissible despite her not being a party below and having authorized the mother to act for her.
Decisione estratta
The daughter's appeal was inadmissible; the mother could still pursue the maintenance claim for the post-majority period because the daughter approved the requested amounts, but the daughter herself lacked standing to file a reform appeal.
Motivazione estratta
Prozessstandschaft continues for post-majority child support only with the adult child's consent, yet a person who was not a party in the cantonal proceedings lacks standing to appeal in reform.
