Question juridique clé
Whether the cantonal surveillance authority adequately reasoned its decision excluding the maintenance payment from the debtor's minimum subsistence.
Solution extraite
The decision was sufficiently reasoned; the debtor could understand and challenge it effectively.
Motifs extraits
The authority stated the decisive reason: a payment made on the basis of a moral duty is only included in the minimum subsistence in very exceptional circumstances, which were not implicitly or explicitly established here.
