Questão jurídica principal
Whether the enforcement office sufficiently clarified the debtor's income ex officio when determining attachable earnings.
Decisão extraída
No. The enforcement office had not adequately clarified the decisive factual circumstances and had to investigate the debtor's actual income more closely.
Fundamentação extraída
The enforcement authorities must determine the relevant facts ex officio, including in supervisory complaint proceedings. Requesting only a wage certificate was insufficient on the record.
