Questione giuridica chiave
Whether the child had a relevant need for support and whether Aargau had to reimburse Zurich for emergency support costs under the ZUG.
Decisione estratta
The child was needy at least initially because no further necessary funds arrived in time; Aargau had to reimburse Zurich for the emergency support costs.
Motivazione estratta
Family-law maintenance claims count as own means only if they arrive in time. After January 2002 no further alimony covered the foster costs, so need existed and Aargau remained the competent residential canton for reimbursement.
