Question juridique clé
Whether the child support advance had to be granted retroactively from the first letter of August 2016 or only from submission of the complete application in January 2018.
Solution extraite
The relevant application was filed only when the completed questionnaire was submitted; the authority therefore correctly started the advance only prospectively from November 2017.
Motifs extraits
A mere informal letter was not yet a request within the meaning of the procedure. The authority needed the completed questionnaire and supporting documents to examine entitlement. The delay in returning the questionnaire could not be shifted to the authority, and reliance on good faith failed.
