Key legal question
Whether flat expense allowances must be added to the debtor's income when calculating the attachable wage portion.
Extracted holding
Flat expense allowances are to be added to the debtor's income; the parties' label of part of the remuneration as expenses does not bind the enforcement office.
Extracted reasoning
Such allowances may partly conceal salary payments, and the employment parties may not indirectly determine the attachable wage quota. The enforcement authority must look to the actual economic value received.
