Question juridique clé
Whether the child had a relevant need for support and whether Aargau had to reimburse Zurich for emergency support costs under the ZUG.
Solution extraite
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.
Motifs extraits
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.
