Kernrechtsfrage
Whether the supervisory authority could estimate the debtor's garnishable income rather than rely on his declared salary
Extrahierter Entscheid
Yes. The authority may investigate the debtor's real economic situation and estimate income from relevant indices when the declared salary appears implausible.
Extrahierte Begründung
The office must not merely record declarations but must inquire into assets and income sources, including economic ownership. Where the debtor's status or declarations are not credible, the authority may rely on available indicators and, if necessary, on an estimate, especially when the debtor occupies a role comparable to an independent earner.
