Kernrechtsfrage
Whether the appellant's set-off declaration was sufficiently specific to be effective
Extrahierter Entscheid
No. The declaration was unclear because, although the appellant identified his total fee claim and the respondents' claims, he failed to specify how the overall counterclaim was allocated against the three separate claims.
Extrahierte Begründung
A set-off declaration is an unilateral, recipient-facing declaration that must clearly identify both the claim to be extinguished and the counterclaim. With several claimants and an overall counterclaim exceeding the combined claims, the debtor had to indicate against which respondent the remaining balance was being set off. Without that specification, the declaration was ineffective.
